Profit & loss statement 

Group sales grew by just under €1 million to €146.5 million (prior year €145.6 million). Expenditure 

increased by €0.4 million during the year under report to €133.6 million (prior year €133.2 million). 

The operating result increased by €0.8 million to €13.2 million, net income was €7.7 million. 

Balance sheet 

The transfer of the balance sheet profit of €7.2 million results – with subscribed capital, capital 

reserves and revenue reserves – in equity of €22.8 million. The equity ratio is 32 percent. 

The accruals for pensions, taxation and remuneration have increased by €4.7 million to €30.6 

million. On the other hand, liabilities, such as trade payables to suppliers and subcontractors 

and payments received on account of orders have fallen by €29.7 million to €17.3 million. 

This results in a balance sheet total for 2010 of €70.8 million (prior year €104.0 million). 

The reduction is largely attributable to the passing of the (German) Accounting Law Modernisation 

Act (BilMoG).

Report of the Supervisory Board 

During fiscal 2010, the Supervisory 

Board reviewed the management of the 

Aktiengesellschaft (stock corporation) 

by the Executive Board and constantly 

monitored business activities through 

written and oral reports of the Executive 

Board. 

The annual financial statement submitted 

by the Executive Board for fiscal 

2010 has been examined following 

accounting undertaken by Wirtschaftstreuhand 

GmbH. No causes for objection 

were found and the annual financial 

statement was certified as accurate 

without reservation. In keeping with 

this, examination of the annual financial 

statement by the Supervisory Board 

raises no cause for objection. 

The Supervisory Board approves the 

annual financial statement submitted by 

the Executive Board and it was thereby 

adopted on May 20, 2011. The Supervisory 

Board approves the management report.

Report of the Executive Board 

More profit through increased efficiency in 2010 – and a good outlook for 2011 

2010 result and outlook 

In 2010, group sales totaled €146.5 

million, slightly above prior year 

(€145.6 million). As a result of the 

focus on profitable activities, the 

operating result was increased by 

€0.8 million to €13.2 million. (prior 

year €12.4 million). This positive 

develop-ment in 2010 is partially the 

result of an improvement in the market 

situation, but above all attributable 

to a service range tailored to our 

national and international clientele. 

Executive Board and Partners (from left to right)

Dierk Mutschler 

Peter Tzeschlock 

International business now accounts 

for 30 percent of total sales, whereby 

project management continues to make 

up the lion’s share at nearly 80 percent. 

Engineering and Real Estate Management 

account for some 20 percent. The 

operating result was achieved by 1,125 

employees in 2010. 

For business year 2011, Drees & Sommer 

will again strive to achieve moderate 

growth while at the same time undertaking 

a project to further increase efficiency 

and quality. To achieve this aim, the 

Group intends to further extend its 

innovation lead and to expand networking 

of its wide-ranging competencies. 

Competent employees: Drees & Sommer 

vocational training concept 

Highly qualified employees are the 

foundation of our success, for which 

reason we have substantially increased 

our investment in vocational training. 

All operational employees are 

taught specific basic knowledge by 

their experienced colleagues in the 

Drees & Sommer ‘Vocational Training 

Academy’. We have created the 

‘Professional’ program, an E-learning 

platform that makes the expertise of 

experienced employees available to 

all employees in a clearly structured 

way. And for top managers we have the 

advanced ‘Excellence’ program.

Opportunities in the energy sector 

Long before the major nuclear crisis in 

Japan, Drees & Sommer had been 

engaging in reducing energy consumption 

and in alternative energy generation. 

The catastrophe in Japan will result in 

a huge increase in the urgency of this 

debate in 2011. The calls to simply 

switch off nuclear power plants cannot 

be treated seriously as long as there 

are no clear alternatives and there is 

no political consensus for their implementation. 

The basic components are 

clear in principle: 

– Reduction of energy consumption 

– Central electricity generation by wind 

and solar plants, and possibly by 

coal- and gas-fired power stations 

with carbon neutralization 

– Cables from wind farms and solar 

arrays to consumers 

– Establishment of storage capacity 

for generated current 

– Decentralized electricity generation 

Drees & Sommer is active both in the 

area of reducing the energy consumption 

of buildings (Green Building, DGNB) and 

Decisive action to save 

Urgent action required – 

reactive 

Speedy action 

Targeted action required – 

strategic 

of industrial plant, as well as in expanding 

the electricity grid (page 12). Also, 

research is being undertaken into the 

use of excess current to produce hydrogen 

and into the conversion of carbon 

emissions. 

Our consulting and management services 

are currently being optimized to cover 

the entire range of electricity generation, 

distribution and storage. 

Portfolio carbon management for CO2 

reduction 

In future, the energy efficiency of whole 

portfolios will have to be assessed – 

particularly in the area of residential 

construction. Drees & Sommer’s portfolio 

carbon management services offer 

a realizable strategy for the reduction 

of carbon emissions during property 

refurbishment. 

Optimizing established properties 

In the near future, established buildings 

will account for some 70 percent of 

construction work. For this reason we 

assume that optimization of established 

properties will continue to dominate the 

property industry over coming years. 

Drees & Sommer offers a comprehensive 

consulting package for property owners 

in this area: 

– Precise determination of life cycle costs, 

including rehabilitation measures 

– Property value analysis: Establishing 

the market value for various levels of 

rehabilitation over 10 years 

– Comparison of book value and market 

value 

Numerous clients already rely on 

Drees & Sommer competence in the 

area of technical construction and 

commercial property valuation and 

consulting (pages 26 to 47). 

High-rise competence 

The Group has numerous reference 

projects in the areas of high-rise 

construction and revitalization, with 

competence in project management 

as well as in Green Building design 

and general technology planning. The 

focus here is on optimal interaction 

between facade and building services 

with the aim of achieving economical

Selective action required – 

proactive 

solutions with the lowest possible 

energy consumption and the assessment 

of Green Building certification options 

(pages 26, 34 and 46). 

International competence in the 

pharmaceutical industry 

In 2010, Drees & Sommer has been 

supporting the B. Braun pharmaceutical 

group with its international expansion 

using its expertise in pharmaceutical 

industry properties. B. Braun has established 

or is planning new subsidiaries 

in Argentina, Brazil, Indonesia, Spain, 

Switzerland, Peru and Vietnam. One 

of the largest projects currently being 

managed is the new F. Hoffmann-La 

Roche headquarters building in Basel. 

When completed, it will be the highest 

building in Switzerland and will accommodate 

some 2,000 employees by the 

end of 2015 (pages 62 and 74). 

Health Care – a market of the future 

The demands on buildings in the 

health-care sector continue to increase. 

Off-the-shelf buildings are a thing of the 

past. Today, every new medical building 

and every clinic modernization is a 

unique and highly complex project. 

Architectural and engineering expertise 

is required in addition to medical knowledge. 

In a fiercely competitive environment, 

the combination of function and 

economy is of decisive importance to 

maintain operational leeway when later 

working under extreme cost pressure. 

Commercial properties 

An increasing number of commercial 

properties need to be refurbished in 

order to remain competitive in the 

marketplace. A current example is the 

revitalization of the Gerngross department 

store in Vienna (page 28). Vienna’s 

largest department store is moving with 

the times, presenting itself in restored 

glory following extensive renovation. 

Drees & Sommer successfully supported 

Gerngross CityCenter throughout the 

modernization project. 

Increasing efficiency: Process consulting 

Drees & Sommer process consulting is 

an interdisciplinary expertise covering 

the full range of services. The experts 

pursue a holistic consulting approach. 

All processes within a company or a 

project are exactly coordinated, so 

that processes interact seamlessly to 

enhance efficiency. As an example, 

Drees & Sommer experts are working 

on the establishment of a modern car 

factory for Fiat in Kragujevac, Serbia 

(page 40). 

Heading north: Drees & Sommer Nordic 

The establishment of Drees & Sommer 

Nordic in the Danish capital Copenhagen 

in 2010 aims at better penetration 

of Scandinavia and the Baltic states. 

Drees & Sommer has already established 

itself in this area with studies in connection 

with the Fehmarn Belt Bridge as 

well as with feasibility studies and due 

diligence projects. There is particularly 

strong potential in the public sector. 

The subsidiary also aims to acquire major 

orders particularly in the clinic sector.

That the ‘garage company’ founded in 

1970 would – within 40 years – become 

an enterprise with over 1,000 employees 

and more than 30 offices was not something 

the two founders Gerhard Drees 

and Hans Sommer were focusing on 

at the time. On September 16, 2010 the 

Drees & Sommer Group celebrated its 

40th anniversary with simultaneous 

client events at 14 German and international 

offices. This once again made it 

clear that the Drees & Sommer spirit is 

very much alive even after four decades. 

Since the company’s foundation it has 

Rino Woyczyk 

Jörg Zirlewagen 

Prof. Dr. Thomas Bohn 

handled approx. 10,000 projects with a 

construction volume of €95 billion. The 

ownership structure of Drees & Sommer AG 

(stock corporation) founded in 1992 

comprises eight non-active and 29 active 

shareholders – the so-called Partners – 

who manage the company today. The 

shareholders are organized as a consortium, 

which is represented by its chairperson 

in the Annual General Meeting. 

Three of the 29 active Partners – Peter 

Tzeschlock, Dierk Mutschler and Gabriele 

Walker-Rudolf – make up the Executive 

Board. Hans Sommer is Chair of the 

Supervisory Board and also a Partner. 

As Managing Directors, the remaining 

25 Partners are responsible for the 

operational sites and expert teams. 

1970s: Foundation phase 

At the beginning of the 1970s, 

Drees & Sommer was able to achieve 

much more exact scheduling using 

the new method of critical path analysis, 

allowing economic construction processes 

to be planned with confidence. 

This was supplemented by precise cost 

and budget planning using the cost 

element method, which has been set 

down in DIN 276 since the 1980s.

Even in this early phase, offices were 

established in Düsseldorf (1973), Munich 

and Cologne (1978) as well as project 

offices in Saudi Arabia and Qatar. 

1980s: Company organization 

The company’s lead in software-based 

schedule and cost planning led to significant 

growth in the 1980s. The engineers 

also started to look more closely at building 

operation, optimizing the so-called 

building utilization costs. This resulted in 

the facility management consulting service. 

Profitability consulting developed from 

increased sensitivity to energy costs. 

Partners (from left to right)

At the end of the 1980s, the company 

had grown to 180 employees. Organizational 

structures were created to do 

justice to continued growth and the 

increasing number of offices. 1988 

saw the introduction of a system – 

still in use today – where the Partners 

manage the individual offices as entrepreneurs 

based on enterprise-wide 

guidelines, naturally taking regional 

practices into account. At the same time, 

a bonus system was established for all 

employees and the Drees & Sommer 

Corporate Philosophy was developed, 

laying down the company’s core values 

Markus Weigold 

Hans-Peter Holler 

Hanns Ludwig Fiechtner 

and guidelines for client relations, 

internal collaboration, and employees’ 

personal responsibility. 

1990s: Accelerated growth 

During this period, Drees & Sommer 

undertook user consulting, coordination 

with authorities and the management 

of architectural competitions for ever 

more complex projects. Increasingly, the 

requirements of as yet unknown users 

and alternative use options had to be 

anticipated and integrated into planning. 

New services were created in the form 

of development management and project 

management for infrastructure measures. 

By the end of the 1990s, Drees & Sommer 

already had over 500 employees. 

The new century 

Since the turn of the century, international 

investors have increasingly replaced 

‘conventional’ principals. There was a 

huge increase in the use of the ROI 

approach and trade with huge property 

packages, triggering a boom in technical 

due diligence in 2007. Public private 

partner projects required the calculation 

of life cycle costs over the entire life of 

the building. At the same time sustain- 

Dr. Jürgen Laukemper 

Roland Huber 

ability became a key issue. As 

one of the first in the marketplace, 

Drees & Sommer developed comprehensive 

economical solutions for 

sustainable building, reduction of 

energy consumption, and energy 

optimization of established buildings. 

In this way, the company is undertaking 

pioneering work in the area of Green 

Building, including being a founding 

member of the German Sustainable 

Building Council (DGNB). 

Currently the focus is on the economical 

optimization of established properties, 

Martin Lutz 

Thomas Hofbauer 

Prof. Dr. Michael Bauer 

as increasingly principals and investors 

have to turn their attention to existing 

buildings and take steps to bring their 

properties in line with the current state 

of the art to enhance their marketability. 

For the future, Drees & Sommer is 

working on ‘industry-based solutions’, 

that is, processes, management and 

consulting services specifically tailored 

to the needs of individual industries.

PROJECT MANAGEMENT FOR OFFSHORE GRID CONNECTIONS 

Collection and safe transmission 

of offshore power 

Generating wind power on the open sea places the maximum demands on people, material 

and management. And the same challenges apply to low-loss transmission to consumers. 

Since 2010, as a member of a consortium, Drees & Sommer has been supporting the planning 

and realization of grid connections for wind farms in the North Sea. 

Legislators in Germany have recognized 

the potential of wind power, in particular 

of offshore wind farms. The German 

Federal Government’s energy concept 

provides for 35 percent of electricity 

consumption to be covered by renewable 

resources by 2020. Over the following 

decades, this share is to continue to rise, 

reaching 80 percent in 2050. 

Wind power will play a key role in the 

expansion of ‘renewables’ (see graphic 

on right). But there is only very limited 

space for wind farms on land and their 

profitability – even in elevated areas 

of the highlands or on the coast – is 

relatively limited. So what better than 

to go where wind and weather come 

together: on the open sea. 

Bringing the electricity of the future 

safely to the consumer 

Generating power off the coast is one 

thing. Getting it as safely as possibly to 

consumers on the mainland – and with 

minimum transmission loss – is quite 

another. The first challenge here is the 

transmission lines themselves, which 

are often up to 200 kilometers long and 

which, when transmitting alternating 

current, are not good conductors. For 

this reason, the current is converted into 

direct current on a floating converter 

platform. A relatively new technology 

called high-voltage direct current (HVDC) 

transmission then takes it from there to 

a transformer station on land, where it is 

converted back into three-phase current 

before being fed into the grid. This is a 

clear demonstration of how offshore wind 

power depends on a well-functioning 

infrastructure on land.

PROJECT MANAGEMENT FOR OFFSHORE GRID CONNECTIONS 

Wind, waves and weather: Even with a calm sea and sunshine, the project demands peak performance from all involved Cable laying from a special ship 

Specialists support specialists: 

mastering challenges together 

TenneT TSO GmbH – together with its 

Bayreuth-based sister company TenneT 

Offshore GmbH – has taken on the 

complex task of connecting the offshore 

systems to the German extra-high 

voltage grid. With some 750 employees, 

it is responsible for the operation, 

maintenance and further development 

of the transmission network at the 

voltage levels 220 kV and 380 kV. Even 

in geographical terms this is, literally, 

a very broad field. The network they 

manage ranges from the coast in the 

north to Bavaria in the south – and has 

a length of over 10,700 km. 

As the responsible network operator 

in the North Sea area, the company is 

legally required to establish and operate 

grid connections offshore wind farms. 

This includes wide-ranging tasks from 

concept development and planning to 

construction and operation of lines at 

sea and their connection to the grid on 

land. In the summer of 2010, TenneT 

got further support on board for these 

tasks. 

Together with its consortium partners, 

the specialists from Drees & Sommer 

have been supporting the customer by 

providing comprehensive project control 

services since September 2010. The 

consortium is focused on establishing 

four grid connections: BorWin2, DolWin1, 

HelWin1 and SylWin1, which are located 

75 and 160 kilometers off the eastern or 

northern Frisian coast – and together will 

collect, convert and transmit power from 

over 600 wind turbines. Together they 

will generate some 11.8 million megawatt 

hours per year and supply approx. three 

million homes with offshore power. 

Scheduling with an eye on the 

weather chart 

The consortium’s project control 

personnel are directly integrated into 

each project team. The joint goal of 

all involved is the control of the prime 

contractors commissioned and the 

successful establishment of the grid 

connection. The Drees & Sommer 

expert team for infrastructure management 

undertakes important tasks 

such as schedule management, cost 

planning & tracking, and risk management. 

In addition, the experts are 

responsible for contract and supplementary 

claim management, the so-called 

Change Request process, as well as for 

documentation of the projects. 

In view of the great challenges involved, 

proper management of risks, contracts 

and supplementary claims is of great 

importance. For example, special approval 

requirements have to be met for laying 

marine cable through the Wadden Sea 

National Park, as construction is only 

permitted there at certain times of the 

year. Nature is a constant – but sometimes 

very unpredictable – companion. 

The experts must take the weather risk 

into account and allow adequate time 

buffers when drawing up and tracking 

schedules, particularly for the construction 

of platforms and cable-laying at sea. 

In view of the offshore wind power 

project boom, the same applies to the 

limited availability of machines and other 

resources, such as cable-laying ships. 

Experience, expertise, manpower: 

nothing convinces like performance 

The clients were convinced above all by 

Drees & Sommer’s long-term experience 

with the control of major 

projects and demonstrated methodological 

competence. The high level 

of specialist qualifications of the 

company’s employees was also 

impressive. The fact that the entire 

consortium showed exceptional team 

spirit and motivation from day one 

was another positive. 

“The chemistry is right” – this has 

been demonstrated by first positive 

results. In an analysis undertaken 

immediately after starting work, 

Drees & Sommer was able to identify 

important potential for optimizing 

organization of the project.

REDEVELOPMENT OF A DISUSED INDUSTRIAL SITE 

Neighbourhood development: Bringing 

people and nature back into town 

Drees & Sommer is successfully supporting the client with the PHOENIX See (Lake PHOENIX) 

project in Dortmund, which involves the redevelopment of a former coal mine site. Efficient 

organization and preparation for one of Europe’s largest earth-moving projects is ensuring 

smooth progress, and an architectural fair has offered a diverse range of architectural styles. 

The fact that “times, they are a-changing” 

has always been evident between the 

Rhine, Lippe and Ruhr rivers, as industrial 

change has molded life in the region 

for centuries. This dynamic is particularly 

apparent in the south of Dortmund, 

where one of Europe‘s largest urban 

development projects is changing the 

face of the city. For 150 years and over 

many generations, the character of the 

district of Hörde was determined by 

heavy industry: In the mid-19th century, 

production and processing of steel 

began on the so-called Phoenix site. 

It was the decline of Germany‘s coal 

and steel industries in the 1970s that 

brought this to an end. The plant was 

closed in 2001 followed by the dismantling 

of equipment and a partial 

sale to China. 

Dortmund seizes the opportunity 

The City of Dortmund seized the opportunity 

by purchasing the site shortly 

before the turn of the century: The 100hectare 

disused site was bought back for 

the people. This gave new impetus to the 

idea of living and working in one place, 

a visionary concept that seemed to have 

been long lost. The inspiration generated 

by this idea can be seen in nearly every 

corner of the district. 

An artificial 25-hectare lake with a 

depth of up to four meters and several 

islands is being created on the site of 

the former Hermannshütte steel plant. 

The lake will be surrounded by 42 

hectares of residential and commercial 

properties, including some 900 homes 

for approximately 2,500 people. 

This will be supplemented by extensive 

parklands totaling about 11 hectares with 

the renatured Emscher River and Hörder 

Stream taking up about 13 hectares. 

The new living and working area will one 

day become part of the Emscher Landscape 

Park, and is an example of the 

‘green’ structural change taking place in 

the region formerly dominated by heavy 

industry. 

Coordination of the planning and 

approval processes 

Clearly the preparation and execution 

of such a fundamental change of use 

for an entire district is a mammoth task. 

Initially, it posed substantial problems 

for those responsible, namely the 

PHOENIX See Entwicklungsgesellschaft 

mbH and the Emscher River Association. 

A 25-hectare lake and extensive parklands will shape the future of the former PHOENIX West coal mine site 

This is where the Drees & Sommer 

infrastructure specialists came into the 

picture in November 2005. The expert 

team helped the principals to achieve 

their goals and to master the associated 

organizational challenges. Since then – 

as project controller – the company has 

been coordinating the activities of two 

principals, numerous authorities, funding 

institutions, planners, consultants, and 

numerous contractors, including about 

40 engineering firms and consultants. 

The construction-related tasks were 

almost as challenging. Following dismantling, 

demolition, remediation and 

safety work, the experts managed all 

foundation and hydraulic engineering 

tasks. At the same time, civil engineering 

works such as a weir system and bridges, 

and building construction projects – 

including a phosphate elimination 

plant to minimize the nutrient content 

of the waters – had to be undertaken. 

Another task was the construction of 

the complete infrastructure with roads, 

paths, squares and parklands. 

Site logistics for a lake larger than 

Hamburg’s Inner Alster 

Earthworks for the lake – which will 

one day be larger than Hamburg’s Inner 

Alster – resulted in huge quantities of 

excavated material: Over a million cubic 

meters of soil had to be transported to 

the correct location with over 300,000 

dump-truck trips. To do this, the 

Drees & Sommer expert team established 

the organizational parameters from 

the very beginning and undertook 

“Drees & Sommer provided us 

with outstanding support.”

comprehensive site logistics throughout 

the entire construction period. 

At peak periods, over 150 major pieces 

of equipment – such as excavators, 

bulldozers, rollers and all types of 

transport vehicles – were in operation 

on the extensive site. 

Timely completion of the demanding 

schedule is an important condition for 

the award of subsidies. Professional 

cost and subsidy management is 

required, as the project is being subsidized 

by the state of North Rhine-Westfalia, 

the German Federal Government 

and the EU. To guarantee the efficient 

application of funds, Drees & Sommer 

is also undertaking comprehensive 

supplementary claim management. 

Marketing and architectural fair 

The lake has been filling with water 

since autumn 2010, gradually giving 

an idea of the future shape of the huge 

site. With the support of established 

Drees & Sommer experts for development 

management, marketing of the 

new home sites is progressing apace 

in parallel with the visible progress of 

construction on the site. 

18 

In November 2009, Drees & Sommer 

organized an innovative architectural 

fair called “Building on Lake Phoenix” 

which received a great deal of attention 

from both the public and experts. Some 

50 architects – mostly from the region – 

presented designs for homes to be 

built on sites around the lake. Upmarket 

detached and duplex homes with 

striking architecture are to be built on 

a good 200 sites on the site’s southern 

slope. Nearly all homesites on this 

southern slope have already been sold, 

with construction to begin from mid 

2011. The remaining 140 sites on the 

southern shore will be marketed at a 

further architectural fair in 2011. 

The specialists hosted a creative workshop 

with architects and communications 

agencies for the planned 

commercial and service buildings on 

the southern and western shores of 

the lake. The event was an immediate 

success, with large areas sold to 

investors. So gradually, life is returning 

to the former industrial wasteland. 

Designs for commercial and service buildings on the 

lake were presented at a creative workshop at the same 

time as rapidly proceeding construction work

INFRASTRUCTURE PROJECT IN THE HEART OF EUROPE 

Pushing the envelope: 

Infrastructure management 

by Drees & Sommer 

Can you push a road tunnel 

under an existing railway 

track? The Drees & Sommer 

experts have proved that – 

with engineering expertise and 

professional management – 

nearly anything is possible. 

Road tunnel 

approx. 120 m 

Freeway tunnel 

approx. 750 m 

A well-developed transport infrastructure 

is essential in densely populated and 

economically powerful central Europe. 

For this reason, the Roads Department 

in Luxembourg (Administration des Ponts 

et Chaussées) is gradually expanding 

its freeway network and – as part of the 

extension of the A4 to France – is also 

providing access to the disused industrial 

site in Belval. 

The entire project involves a series of 

subprojects such as the rerouting of the 

national road, the laying of an oxygen 

pipeline, and the construction of a 

750-meter long freeway tunnel (Liaison 

Micheville) through Belval using a partial 

cut-and-cover process. A later project will 

link this tunnel to the freeway junction 

at Lankëlz. The key purpose of the tunnel 

is to direct cross-border traffic between 

Luxembourg and France away from the 

villages of Esch-sur-Alzette and Sanem. 

Push: A heavy load on strong shoulders 

A complex infrastructure project of this 

nature demands professional management, 

above all to ensure that budget 

and schedules are adhered to. With a 

long track record of experience in this 

area, Drees & Sommer convinced the 

government principal of its expertise and 

supported the entire project professionally 

from the beginning. In addition to 

specialist expertise, the experts were 

Tunnel jacking using the Autofonçage® technique, here with a 120 m road tunnel 

able to present a portfolio of successfully 

completed local projects. 

A special challenge for the project participants 

was the routing of the freeway 

under a key railway line. The process 

by which the necessary tunnel is ‘simply’ 

pushed under the tracks is known throughout 

Europe as Autofonçage® (tunnel 

jacking), but never before has it been 

undertaken with a weight of 20,000 

tonnes, equivalent to 16,000 mediumsize 

cars. 

The first step in the process is to dig a 

rough pit with stable sloping side walls. 

As the tunnel section is positioned, the 

sides of the pit are further excavated 

across the entire width of the structure to 

form vertical walls. As the structure slides 

into place, it immediately supports the 

vertical pit walls. This process is repeated 

for the entire insertion length – in this 

case 59 meters (see illustration above). 

The operation was a complete success: 

The tracks only had to be closed for some 

72 hours, after which the rail traffic could 

resume its schedule. 

Huge responsibility – from cost 

controlling to waste disposal 

Since 2006, Drees & Sommer has been 

responsible for project control and cost

MULTIPROJECT MANAGEMENT FOR 85 INDIVIDUAL PROJECTS 

Many thanks for the flowers: 

State Garden Festival open on schedule 

Drees & Sommer successfully undertook project control for the State Garden Festival in Hemer. 

Transformation of the development site of more than 30 hectares into the garden festival grounds 

was accompanied by extensive infrastructure measures. 

Up until October 2010, State Garden 

Festival visitors were able to enjoy flower 

beds, themed gardens and architectural 

highlights at the 300,000 square meter 

site in Hemer in North Germany’s 

Sauerland. What started with the motto 

“The magic of transformation” with the 

award of the festival to the City of Hemer 

in 2007 was successfully realized with 

the opening of the State Garden Festival 

in April 2010. 

Management of 85 individual projects 

Working in consortium with Herbstreit 

Landschaftsarchitekten (landscape 

architects), Drees & Sommer undertook 

project management for some 85 

individual projects. These included the 

installation of telecommunications 

systems, extensive road works, and the 

design and construction of open spaces 

and public squares. The principal – 

Landesgartenschau Hemer 2010 GmbH – 

together with the City of Hemer, also had 

numerous older buildings renovated for 

use as offices, public amenities, commercial 

and service premises. 

Extensive construction work was 

designed to strengthen the residential 

and urban center function of downtown 

Hemer, giving it a new character and 

profile. The concept for the State Garden 

Festival’s outdoor areas also had to take 

intended later use into account. Focal 

points were the new Cultural Quarter 

with a multipurpose hall, city terraces 

and a ‘Felsenpark’ (rock park) directly 

connected to the nature reserve. 

The experts had to work to a tight 

schedule of only 20 months. During the 

execution of the project, the City of 

Hemer awarded additional contracts to 

Drees & Sommer. 

Additional subprojects – initially 

outside the scope of the overall control 

contract – also added to increasing the 

scope of construction work and project 

control services from €36 to €51 million, 

albeit without any extension of the 

project duration: The opening date of 

April 17, 2010 was set in concrete.

Control of interfaces 

The coordination and control of interfaces 

to the individual projects was 

a special challenge for the project 

managers. In addition to project control, 

planning had to take the implementation 

of urban-development infrastructure 

measures into account: Many projects 

were undertaken in parallel and many 

had to be completed before other infrastructure 

measures could commence. 

For this reason, the project managers 

also controlled the execution of subprojects 

with the planners involved and 

the integration of development sites 

into the existing infrastructure. 

To allow active intervention to counter 

disruption of project execution, the per- 

tinent interfaces for all planning phases 

were identified and constantly updated. 

Drees & Sommer kept a daily close eye 

on schedules, costs and quality to ensure 

early detection and rectification of any 

critical situations. This comprehensive 

multiproject management ensured 

smooth execution of the overall project 

taking all parameters into account. 

Integration of military sites 

With many years of experience in the 

redevelopment of former military sites, 

Drees & Sommer was able to support the 

principal with all aspects of conversion. 

The integration of the old barrack site 

into the ‘Felsenmeer’ (Sea of Rocks) – 

a nature reserve declared in 1968 – 

was completed as planned, as the results 

of the soil analysis and additional 

feasibility studies gave the go-ahead 

for the next planning stages. 

Transparent interface coordination and 

detailed project communication meant 

that the principal had a comprehensive 

overview of the status of the individual 

projects at all times. Despite the unfavorable 

weather conditions in Winter 

2009/2010 and the resultant delays, 

Drees & Sommer was able to ensure the 

timely completion of this major project. 

The State Garden Festival far exceeded 

expectations: Instead of the anticipated 

500,000 visitors, 1,050,326 people 

made their way to Hemer, setting a new 

attendance record for a State Garden 

Festival.

CERTIFICATION AND MARKETING OF AN ESTABLISHED PROPERTY 

LEED Gold for Trianon 

On the Frankfurt property market, the name Trianon is a 

guarantee of quality. In future, it will also be associated with 

low operating costs, ecological sustainability and high user 

comfort. With the support of Drees & Sommer, the building 

has achieved LEED Gold Green Building certification, thus 

substantially strengthening its position on the market. 

A coherent overall concept is essential 

if you want to be a leading player in the 

market for commercial Green Buildings. 

For sustainability certification, the 

relationship between costs, consumption 

and needs of people working in the 

building have to be taken into account. 

This applies particularly to established 

properties for which adequate rating 

systems have only recently become available 

thanks to special criteria developed 

by popular Green Labels. A successful 

methodology requires a combination of 

careful analysis of the property and the 

selection of the right optimization measures. 

This requires long-term practical 

experience with this type of building 

as well as up-to-date theoretical knowledge 

about the current status of Green 

Building research. 

Innovative Green Building management 

by established experts 

The Trianon building is managed by 

argoneo, an asset management company 

active throughout Europe with numerous 

well-known properties in its portfolio. 

argoneo has set a clear goal for the 186- 

meter high Trianon in Frankfurt’s banking 

district: High tenant satisfaction is to 

be ensured for the future – and the 

building will continue to be marketed as 

an extremely attractive office address. 

As an innovation leader in the area 

of Green Building – with extensive 

experience in high-rise and established 

buildings – Drees & Sommer was able 

to win Trianon as a client. Since June 

2009, they have been jointly striving to 

achieve a Gold LEED for Existing Buildings 

rating. In 2011, Trianon will be the 

first established building in Germany 

to achieve the Gold rating of this special 

LEED variant developed for existing 

buildings. 

Assess, optimize, monitor 

The certification process began with 

a fundamental energy assessment 

of the property. This initial analysis 

was undertaken by an experienced 

Drees & Sommer expert team. Based 

on the results, a strategy for further 

action was developed. As part of this, 

Drees & Sommer is currently securing

During the actual preparatory phase for 

certification – which lasts approximately 

one year – the experts turn their attention 

to the optimization of building operation. 

To do this, they examine numerous processes 

in the Trianon, such as material 

flows with regard to the use of office 

materials or waste disposal. In order to 

be able to optimize effectively, the 

building’s energy consumption is being 

monitored with state-of-the-art tools. 

An energy pass – but above all a Goldrated 

LEED certificate – will help the 

Trianon to attract the level of attention 

a building of this calibre deserves. In 

particular, this will bring home the fact 

that the Trianon is a building which is a 

joy for operators and users alike.

RETAIL RENOVATION DURING FULL OPERATION 

Gerngross department store: 

comprehensive modernization 

for shopper magnet 

Vienna’s largest department store is moving with the times and, 

following extensive refurbishment, has been restored to its former glory. 

Drees & Sommer successfully accompanied the Gerngross CityCenter 

during this modernization project. 

Built in the 1960s, the current Gerngross 

building is located directly on Vienna’s 

largest shopping boulevard, the Mariahilfer 

Straße. As the tradition-steeped 

department store was no longer meeting 

modern requirements for profitability 

and functionality, the site owner DEKA 

Immobilien Investment GmbH decided 

to carry out extensive refurbishment. 

An architectural competition was held – 

and was won by the Graz-based firm 

LOVE architecture and urbanism. 

Drees & Sommer came on board in 

June 2008 and was commissioned 

to undertake project control. 

Optimization of existing property 

The interior was to be upgraded to 

improve the economic success of the 

department store by providing it with 

a contemporary image. As a result, 

the atrium was completely redesigned 

and building services equipment 

and elevators renewed. Thermal rehabilitation 

– including the installation of 

high-grade windows – contributed to the 

optimization of energy consumption. 

To prevent financial losses, the owner 

decided to undertake the reconstruction 

with the shopping center in full operation. 

The challenges for the project team 

involved providing access to the indi- 

vidual stores while at the same time 

ensuring the safety of customers 

and users and avoiding any negative 

impact on neighbouring infrastructure. 

Based on these complex parameters, 

Drees & Sommer developed a detailed 

construction process plan for each 

floor and construction phase. 

As a result of its contemporary image with a striking 

facade the tradition-steeped department store is once 

again a highlight on the Mariahilfer Straße 

28 29

RETAIL RENOVATION DURING FULL OPERATION 

The entire facade underwent thermal rehabilitation 

and has been technically modernized. Individual 

blocks in the interior give structure to the levels. 

Professional tenant management 

A maximum of four months was available 

for each floor for construction, 

including tenants moving out and back 

in. Drees and Sommer coordinated all 

measures closely with the center 

management, who represented the 

tenants’ interests, and with the general 

planner. In a masterful logistical achievement, 

existing tenants were moved to 

temporary space during remodeling. 

As part of the complete revitalization, 

the building was fitted with a new 

thermal facade, including the externally 

suspended metal facade. 

Another challenge was the inner-city 

location on Vienna’s largest shopping 

boulevard. The planning of a complete 

building site directly next to the subway 

and limited working hours that did 

not allow noisy night work, also had 

an impact on construction execution. 

Green Label certification by 


In addition to project control, 

Drees & Sommer also looked after 

technical tenant coordination and 

Green Building certification in accordance 

with the EU label. The client 

specifically wanted a sustainable 

approach, as this reflects not only 

market needs but also customer expectations. 

In addition to ecological and social 

considerations, certification was 

primarily aimed at profitability, for 

example through the reduction of 

building operating costs. Initially, a 

Green Building Quick Check for LEED, 

BREEAM and DGNB was carried out, 

with the decision finally being made 

in favor of EU Green Building certification 

and BREEAM.

SYSTEMATIC INVENTORY AND OPTIMIZATION OF PROPERTIES 

Experts develop 

action plan for 170 schools 

As part of an inventory of Stuttgart schools, Drees & Sommer inspected nearly 500 buildings. 

Based on the results, the specialists will define the necessary rehabilitation measures and 

develop an overarching strategy. The project received a large amount of media attention. 

An evaluation sheet helped with the prioritization of rehabilitation measures 

After detailed discussions, in early 2010 

the Stuttgart City Council agreed a €100 

million investment package for Stuttgart 

schools. This followed repeated complaints 

from students and teachers about 

the state of their classrooms, gymnasiums, 

and stairwells. 

The city looked for a suitable service 

provider to put the entire process of a 

broad-based upgrade of the property 

portfolio on a technically sound footing. 

Drees & Sommer was the successful 

bidder in a field of eleven responding to a 

public invitation to tender in spring 2010. 

The company was able to convince the 

council of its long-term experience in 

strategic property consulting and its 

expertise with structures and methods 

developed as a result. Other positives 

included competence in economic 

operation of buildings and the optimization 

of large property portfolios. 

Cataloging defects, evaluating and 

prioritizing countermeasures 

The majority of school buildings were 

built between 1950 and 1970. First up, 

the expert team had to physically inspect 

nearly 500 properties, systematically 

recording the state of the building fabric. 

In total, the experts carried out Quick 

Checks on nearly one million square 

meters of property, focusing not only on 

building defects, but also primarily on 

building services equipment deficiencies. 

Following the inventory, all information 

was evaluated and structured in a 

database. This information formed the 

basis for the development of a rehabilitation 

timetable. Taking growth plans 

for the individual schools into account, 

the timetable defined the relative 

urgency of rehabilitation measures. 

In this way, the timetable provided the 

City of Stuttgart with the basis for making 

decisions on necessary investments 

over coming years.

GREEN BUILDING CONCEPT AND CERTIFICATION FOR AN EXISTING HIGH-RISE 

Sustainable optimization of 

existing properties: 

a key element for top success 

In the 1990s the MesseTurm in Frankfurt’s Westend was the highest building in Europe. 

It is still a striking feature of the skyline today. And now the iconic high-rise will once again 

set standards for years to come with a holistic Green Building and energy efficiency concept 

developed by Drees & Sommer. A LEED certification is supporting the marketing of space 

for lease. 

The market for office space in Frankfurt 

is on the move. Particularly in upmarket 

property locations, landlords have to 

present solid arguments to convince 

potential tenants of their product. Users 

no longer accept ‘average’ for such key 

criteria as building operation costs (the 

so-called ‘second rent’), and well-being. 

GLL Real Estate Partners GmbH, the 

owner of the MesseTurm, was quick to 

realize this. The company was proactive, 

staying ahead of market trends: The 

257-meter MesseTurm – completed 

in 1991 – is to be future-proofed both 

economically and in terms of energy 

consumption by the year 2016. The 

desire for a suitable overall concept for 

energy optimization of the high-rise 

brought the company into contact with 

the specialists from Drees & Sommer. 

Inventory analysis, goal definition and 

concept development 

Drees & Sommer experts began with a 

detailed examination of the building. 

The results showed that optimization 

of the original planning could result in 

substantial energy savings. This required 

discarding the energy concept developed 

when the MesseTurm was built and the 

development of a totally new holistic 

approach. The relationship between 

individual factors impacting on energy 

“We want to work with 

Drees & Sommer to reduce 

the primary energy factor by 

40 percent by 2016.” 

Ingo Langner, GGM Gesellschaft für 

Gebäude-Managament mbh, Property Manager 

MesseTurm at EXPO Real 2010 

demand and the environmental quality 

in the rooms has to be considered in new 

ways. This applies to services including 

heating, ventilation and air conditioning 

of the building. 

By 2016, Drees & Sommer will achieve 

an optimum balance, maximizing user 

comfort while ensuring minimum energy 

consumption. At the same time, various 

building services equipment innovations 

will be introduced. The expert team is 

working with GLL Real Estate Partners 

GmbH and the MesseTurm operator GGM 

Gesellschaft für Gebäude-Management 

mbh, to develop a concept for the phased 

introduction of energy-related modernization 

tailored specifically to the building. 

The goal is to achieve a significant 

reduction of primary energy demand 

of 40 percent, thus also substantially 

reducing carbon emissions. To confirm 

and effectively communicate the economic 

and ecological efficiency of the 

MesseTurm, certification of the building 

with LEED Silver for Existing Buildings is 

planned for as early as 2011. 

Modernization in full operation 

The overall context of the project is highly 

demanding. Not only must government 

requirements such as smoke extraction 

and fire prevention regulations be taken 

into account. Optimization of an existing 

building – whilst allowing tenants to 

continue working undisturbed – is, so to 

speak, a master class in modernization. 

And this is no accident. By undertaking 

similar projects over past decades, 

the company knows what the market 

demands and has accumulated immense 

practical experience. The client benefits 

directly from this expertise: As an attractive 

location, Frankfurt’s iconic high-rise 

will continue to attract upmarket tenants.

PROJECT CONTROL FOR SPORTS FACILITIES 

Chiemgau-Arena on 

track for success thanks 

to professional project 

control 

Even before the starting gun, Drees & Sommer had won 

the race against time. Under extreme time pressure, 

the experts ensured that the traditional biathlon winter sports 

arena in Ruhpolding was once again fit for use as an 

international competition venue. A winner for the principal, 

athletes and winter sports fans. 

September 2008 was a time of celebration: 

The municipality of Ruhpolding 

in south-eastern Bavaria had just been 

awarded the rights to host the 2012 IBU 

Biathlon World Championship. It was 

clear to the organizers, however, that 

the old stadium would no longer meet 

the International Biathlon Union’s 

requirements for such an event. Not 

only was there not enough seating for 

spectators, but the competition facilities 

were also not in keeping with the current 

IBU guidelines. The stadium building, 

the entire infrastructure, the crosscountry 

trails and bridges as well as 

floodlighting and artificial snow ma- 

chines would have to be replaced or 

upgraded. 

Only a short time was available, as all 

work had to be completed by the end 

of 2010 – a period of only ten months. 

The commissioning date was set in 

concrete: mid-January 2011. The reason? 

The 2011 World Cup, a major international 

event highly popular with both 

the public and the media, was to be 

used as a dress rehearsal for the Biathlon 

World Championship in 2012, to the 

delight of fans the world over. Another 

requirement was strict adherence to 

the budget of €16.4 million. 

Successful dress rehearsal: In January 2011 

nearly 90,000 enthusiastic biathlon fans celebrated 

the 2011 World Cup with their stars in the Chiemgau- 

Arena.

PROJECT CONTROL FOR SPORTS FACILITIES 

Professional management enabled realization 

in record time: The Chiemgau-Arena was rendered 

fit for competitions within a few months 

An elegant concept from the start 

Right at the beginning of the project, 

the Ruhpolding Municipal Council commissioned 

Drees & Sommer to develop 

a master plan. In doing so, the client 

consciously chose a company with 

extensive experience in winter sports. 

For example, the project managers were 

able to demonstrate expertise from 

project control of the 2005 Nordic Ski 

World Cup in Oberstdorf. 

Now, as then, the experts were impressive 

in every respect. Together 

with the principal and users they were 

able to translate all requirements and 

wishes into an elegant overall concept. 

The proposed measures were coordinated 

with subsidy providers and 

approval authorities at an early stage, 

leading to optimal cost and schedule 

stability. 

One of the many unique features 

of Ruhpolding was the fact that the 

construction site was located in a 

water protection area, a landscape 

conservation area, a nature reserve, 

and a flora & fauna habitat. This meant 

that further close coordination with the 

appropriate regulatory authorities was 

of great importance. With the support 

of additional consultants and specialists, 

Drees & Sommer coordinated timely 

building approval involving a total of 

some 30 permits. An active on-site 

presence resulted in project managers 

quickly establishing a rapport with all 

parties involved. 

Professional project organization and 

control 

To complete all construction work in 

2010 and ensure completion in time 

for the 2011 World Championship, 

demolition began immediately after the 

last day of competition in March 2010. 

Drees & Sommer supported the Municipality 

of Ruhpolding with project leadhouse 

functions and project control 

services for all individual subprojects, 

delivering systematic project organization 

as well as schedule and cost 

planning. The professional control of the 

project team and construction processes 

ensured adherence both to the budget 

and to the ambitious schedule. After a 

construction period of only ten months, 

training and competition resumed at the 

Chiemgau-Arena as planned and the 

Master plan: Well planned is half built 

2011 World Cup was successfully hosted. 

The Chiemgau-Arena is now a shining 

example of environmental protection 

and operational cost savings: All new 

buildings obtain their heat energy via 

groundwater heat pumps. So bring 

on the Biathlon World Championship! 

Ruhpolding is very well prepared.

OPTIMAL CONSULTING ON FACTORY UPGRADE 

Fiat: High value-add through 

efficient production workflow 

Drees & Sommer is carrying out a project audit for a factory extension and the production 

launch for a new Fiat model in Kragujevac, Serbia. The factory – which dates back to the 1950s – 

is to be completely rehabilitated and modernized. The Fiat group is investing approximately 

one million Euros in car production at the new site. 

With its brands Fiat, Lancia, Alfa Romeo, 

Abarth and Maserati, Fiat Group Automobiles 

is one of the world’s top ten 

automobile manufacturers. It is currently 

undergoing structural change. On the 

one hand, its partnership with Chrysler 

should lead to synergy effects, while 

on the other hand the company plans 

to continue internationalization of its 

brands and expansion of production 

capacities in ‘low-cost countries’. In this 

context, from mid-2012 the successor 

Scope of audit management by Drees & Sommer 

model to the Fiat Idea will be manu-factured 

at the former Zastava plant in 

Kragujevac, Serbia, managed as a joint 

venture between the Serbian state and

modernized for the launch of the new 

model. 

Investment: One billion Euros

in comparison to other Fiat Group sites 

worldwide and are characterized by 

greater manufacturing content.

Project audit 

Drees & Sommer is supporting the 

project by carrying out a project audit. 

During the construction phase as well 

as during the development & integration 

of the production plant, all processes 

relevant to on-schedule, within-budget 

implementation to the required quality 

standards will be continuously monitored. 

Any deviations will be recorded, 

and any necessary countermeasures 

initiated. 

The immense size of the production 

halls – some of which are in a critical 

condition – has to be emphasized. As 

a result, substantial decontamination 

work has to be carried out in parallel to 

extensive remodeling and upgrading. 

At the same time, it must be ensured 

that production can continue unhindered 

while this work is carried out. 

Regular Reporting to client 

The key task of the Drees & Sommer 

project team is to identify risks in the 

project and to communicate these to 

the client. 

The Managing Director of Fiat Automobiles 

Serbia (FAS) and group management 

in Turin are kept informed about 

the current project status, any improvement 

measures implemented and the 

overall progress of the project in regular

MUSEUM REDEVELOPMENT 

Städel Museum, Frankfurt: Refurbishment 

and expansion in full operation 

For decades, the Städel Museum in Frankfurt has attracted art-lovers from all over 

the world. But the building has become cramped, with many exhibits hardly ever 

leaving the storeroom. A great deal of effort was put into finding a solution under 

the motto “Frankfurt builds the new Städel Museum”. Drees & Sommer is supporting 

the principal by acting as project controller. 

42 

Visualizations: © schneider+schumacher, Frankfurt am Main 

When Johann Friedrich Städel endowed 

his collection in 1815, he would never 

have dreamed that it would one day contain 

some 2,800 paintings, 600 sculptures, 

500 photographs and over 100,000 

drawings and prints. And he would perhaps 

have taken pride in the fact that – 

a good 200 years later – the museum 

needed its fourth extension. 

But Städel’s successors have taken 

action. In view of the acute shortage of 

space, the Städelsche Kunstinstitut 

(Städel Art Institute) is currently expanding 

the museum, which dates back to 

the 1870s. The project is being supported 

by companies, foundations, private 

donors and the public purse – to the tune 

of some €45 million. Of this, €14 million 

are being used for refurbishment of 

the existing museum and €31 million for 

the construction of the spectacular 

underground annex, the Garden Gallery. 

200 skylights are the trademark of 

the expanded Städel museum. Their impact 

is striking, both inside and out 

Project control in good hands 

At the explicit request of the principal, 

Drees & Sommer has been acting as 

project controller for the project since 

the end of 2008. For the managers 

responsible, the Städel Museum 

extension is one of the highlights of 

their careers. On the one hand, it is 

about nothing less than ensuring future 

generations access to an important 

cultural heritage. On the other, the 

experts are also stimulated by the 

project’s challenges. 

The strict budgetary constraint, the 

short construction period and the 

complex nature of the work – some of 

which has to be carried out with the 

museum in full operation – require total 

commitment. One of the major features 

of the project was high security for 

numerous world-famous exhibits. 

43

MUSEUM REDEVELOPMENT 

Sophisticated lighting and climate 

control 

The design by the architectural firm 

schneider+schumacher provides 

for the museum annex to be built 

under the existing Städel Museum 

gardens. The annex – illuminated by 

195 circular skylights – will generate 

2,500 square meters of exhibition 

space, primarily for contemporary art. 

The ceiling of the underground space 

curves gently, providing a unique 

spatial experience. And outside, this 

curvature turns the overlying lawn 

into a landscape. 

An integral element of the new rooms is 

a sophisticated lighting concept which 

allows a seamless transition from natural 

to artificial light, as well as an efficient 

state-of-the-art climate control system 

which includes geothermal, building 

component activation, and a humidification/dehumidification 

system that 

guarantees an appropriate climate for 

the artworks even when there are large 

numbers of visitors in the gallery. 

Clearly, a building site of this nature 

makes very special organizational, 

technical and logistical demands and 

requires professional oversight: 

The project controller’s tasks include 

management of the tender and contract 

award processes, contract management 

for planning and construction services, 

and interface definition. 

Coordinating multiple building sites 

To complete the construction project in the 

shortest possible time, Drees & Sommer 

divided it into ten staggered phases. For 

example, until March 2010, only external 

construction work was undertaken. Work 

monitored by the experts during this time 

included the installation of 300 drilled 

piles in the building pit. With the exception 

of the West Wing, the museum 

will be closed between March 2010 and 

November 2011 for work on the shell. 

In the summer of 2010, refurbishment 

of the neighbouring Städelschule school 

started with the school in full operation. 

In March 2011, Drees & Sommer handed 

over the building shell of the underground 

galleries. 

In the meantime, Frankfurt awaits the 

coming autumn with anticipation: From 

November 2011 to February 2012 the 

museum – which has been closed in the 

January 2011 saw completion of the breakthrough between the old and new buildings A dozen columns support the concrete roof of the Garden Gallery 

meantime – and the new Garden 

Gallery will open in stages and feature 

a completely new presentation of the 

collection.

COMPLETE REFURBISHMENT OF DEUTSCHE BANK TOWERS IN FRANKFURT 

Redefining ecological 

standards 

On February 24, 2011, the Deutsche Bank Towers were officially 

reopened after a three-year refurbishment period. The renovation 

of the towers is an innovative, sustainable and pioneering 

achievement which sets new standards for the refurbishment 

of buildings in the future. 

While retaining the external appearance 

of the Deutsche Bank’s twin towers – 

which have become a key landmark both 

of the city of Frankfurt and of Germany 

as a financial center – the existing facade 

was completely replaced by a new 

technically sophisticated, energy-saving 

facade structure. The Milan-based designer 

and architect Mario Bellini has 

transformed the interior with a creative, 

modern design concept. In particular, the 

building’s light-flooded entrance area with 

its space-filling sculptural sphere stands 

for transparency and openness. The use 

of modern energy-conserving technologies 

and pioneering engineering solutions has 

made it in one of the most eco-friendly 

high-rise buildings in the world. 

Sustainability and innovation have 

been recognized by the award of two 

internationally renowned Green 

Building certificates. The new Deutsche 

Bank towers have been awarded LEED 

Platinum for New Construction and 

Major Renovations and DGNB Gold for 

Complete Refurbishment of Office 

Buildings. Management and engineering 

specialists from Drees & Sommer – 

together with the Deutsche Bank 

planning and project team – had the 

exciting task of undertaking the ecological 

rehabilitation of an existing 

building. Together, the teams further 

optimized and developed established 

technical systems. In addition to this 

ongoing development and optimization, 

new standards were established for 

the rehabilitation of high-rise office 

buildings, and innovative workplace and 

spatial concepts were developed and 

implemented on site.

COMPLETE REFURBISHMENT OF DEUTSCHE BANK TOWERS IN FRANKFURT 

The space-filling sculptural sphere stands for transparency and openness 

Global player takes responsibility 

It all started as the result of a special 

assessment by building inspectors in 

2004. As fire prevention measures had 

to be upgraded, Drees & Sommer 

examined various refurbishment levels 

and scenarios. The Deutsche Bank 

then decided to opt to vacate the entire 

premises and to undertake full Green 

Building renovation. Additional goals 

were architectural remodeling of the 

interior and better integration into the 

urban environment. 

Overall concept results in savings 

across the board 

Optimum coordination of all individual 

measures such as the installation 

of over 2,000 parallel opening windows 

48 

in the facade, a ceiling heating and 

cooling system, and a custom-designed 

luminaire made it possible to achieve 

significant consumption savings – 

and resultant cost savings – in nearly 

all areas. 98 percent of all materials 

removed during the refurbishment were 

reused or recycled. 

Following the modernization, the two 

towers use 67 percent less energy for 

heating and cooling – the same amount 

of energy as used by 750 single-family 

homes. At the same time, the power 

consumption was cut by 55 percent and 

water consumption was reduced by 

74 percent. The water saving is achieved 

by a highly efficient water management 

system involving building-internal water 

recycling, rainwater harvesting and the 

use of water-conservation technologies. 

The complete package of measures 

also results in a considerable reduction 

of carbon emissions. Carbon emissions 

from building operations have been cut 

by 55 percent and the use of renewable 

energy sources for electricity means 

a further 34 percent reduction, thus 

achieving an 89 percent reduction in 

pollution overall. The saving is equivalent 

to taking 6,000 cars driving an average 

of 12,000 kilometers per year off the 

road. And on top of all this, there has 

been a substantial increase in efficiency 

and the number of workplaces has risen 

from 2,500 to 3,000 while at the same 

time enhancing the well-being of users. 

The renovation of the Deutsche Bank Towers has 

resulted in an innovative, sustainable and pioneering 

building which sets new standards for the refurbishment 

of buildings in the future 

Services made to measure 

In addition to providing familiar services 

such as Project management, Engineering 

and Green Building consulting, new 

services were developed and existing 

services adapted to the demands during 

the course of the project.

GENERAL CONSTRUCTION MANAGEMENT FOR NEW TEACHING AND RESEARCH CENTER 

Drees & Sommer is responsible for planning and implementing the Bildungscampus 

Heilbronn (Heilbronn Education Campus) on behalf of the Dieter Schwarz 

Foundation. After a construction period of just one and a half years over 1,000 

people will study and work there. This speedy completion was made possible by the 

highly efficient General Construction Management (GCM) implementation model. 

A single source for 

development, planning and 

construction management 

Knowledge is the raw material of the 

future. The acquisition and systematic 

expansion of knowledge are of increasing 

importance in global competition. In 

Germany, private organizations are 

joining state education facilities in 

successfully sharing the responsibility 

for teaching and research – as is the 

case with the Dieter Schwarz Stiftung 

(foundation), which has been promoting 

education, personal development and 

research since 1999. In order to promote 

interdisciplinary exchange between 

various disciplines and faculties, the 

foundation took a far-reaching step in 

2008 in deciding to establish a new 

facility in the center of Heilbronn that 

would – for the first time – bring teachers 

and students from state and private 

educational establishments together. 

This vision is currently taking shape: 

The so-called Bildungscampus Heilbronn. 

From 2011, the German Graduate School 

of Management and Law (GGS), the 

Heilbronn Campus of the Baden-Wuerttemberg 

Cooperative State University (DHBW), 

and the Academy for innovative Education 

and Management (AIM) will occupy 

four modern buildings there. 

Communication drives knowledge – 

the Heilbronn Education Campus offers 

the ideal setting for this 

“ … one-stop shopping for planning, 

all cast in the same mold: That 

obviously offers numerous benefits 

not only for architecture, but also 

for economy and, not least of all, 

scheduling.” 

Dr. Erhard Klotz, 

CEO, Dieter Schwarz Stiftung

GENERAL CONSTRUCTION MANAGEMENT FOR NEW TEACHING AND RESEARCH CENTER 

Experience in managing complex 

projects 

Given the scope of the project, the 

principal was looking for management 

experts who could not only provide 

competent consulting, but could also 

control the project professionally 

throughout the entire planning and 

implementation phase. It is no accident 

that Drees & Sommer was chosen. 

Even back in the 1990s, the company’s 

work on the Potsdamer Platz in Berlin 

demonstrated that it can swiftly and 

safely bring even highly complex major 

projects to a successful conclusion. 

The Dieter Schwarz Stiftung specifically 

chose this expertise for the Heilbronn 

Education Campus, commissioning 

Drees & Sommer to control all planning 

and construction processes. The 

company’s management and engineering 

experts are thus responsible for all 

specialist planning, tendering and construction 

management processes and, 

as a subset of this, for coordinating 

the interfaces to all parties involved, 

including architects, construction 

companies and public authorities. 

But Drees & Sommer laid the groundwork 

for a successful GCM project 

before contracts were even awarded: 

The experts have been supporting the 

Heilbronn Education Campus project 

since way back in 2007. 

A feasibility study and a detailed site 

analysis drew attention to the current 

construction site in the Mannheimer 

Strasse. As the next step the company 

managed the architectural competition 

for the buildings currently under 

construction. Even at this early stage, 

Drees & Sommer consulted the later 

users, ensuring that the new buildings 

would reflect their wishes and requirements. 

Whether building physics or Facility 

management – all have a common goal 

With its combined expertise, the 

Drees & Sommer Group drives the 

whole project using the same principle 

as the Heilbronn Education Campus 

itself: bringing various faculties together 

and using their interfaces to 

ensure that they mesh productively. 

With GCM, the company’s internal 

specialists’ role includes the entire 

web-supported project communication, 

user management, building physics, 

system planning, fitout, and equipment 

planning as well as facility management 

consulting. The latter ensures 

functional and economic operation of 

the three educational establishments 

for years to come – long after the first 

graduates of the Heilbronn Education 

Campus have their diplomas and 

degrees in the bag. 

Keeping a close eye on all key milestones and the 

ultimate goal: Construction process simulation for 

the months of April, July, September and December 

2010 and visualization of the completed campus.

PROJECT CONTROL AND PROFITABILITY CONSULTING FOR NEW CLINIC BUILDING 

New building with 

clinic in full operation 

To maintain its high level of patient care in the future, following on from 

the “New Western Annex”, Brandenburg City Clinic is building a 23,000 

square meter building with over 300 beds in the second stage of its new 

clinic construction program. Drees & Sommer undertook project control 

and provided the ProjectCommunicationSystem (PCS). 

Rich in tradition, the hospital offers 

patients state-of-the-art treatment – 

from laser eye operations to computeraided 

brain surgery. New buildings 

and processes have become necessary 

over recent years to ensure maintenance 

of this high level of care. 

The principal’s goal was a fundamental 

restructuring of the site. This not only 

involved improvements to building fabric, 

but also the consolidation of operational 

processes. The particular difficulty was 

that construction of the new buildings 

had to be undertaken with the clinic in 

full operation. A real challenge given 

the 22,000 in-patients treated each year. 

Project control and communication 

From 1998 to 2002, Drees & Sommer 

had already been commissioned to 

undertake project management for the 

first expansion phase. As a result of their 

positive experiences during the first 

phase, the principal was happy to turn 

to Drees & Sommer again, awarding the 

company the contract for the second 

phase. The company’s specialists have 

been commissioned to undertake project 

control and project communication. 

A temporary building was first constructed 

for the current ‘Eastern Annex’ phase. 

This accommodates the wards from the 

buildings that had to be demolished. Over 

the entire period of the project, highest 

priority is being given to safe patient care, 

which is only possible if all construction 

processes dovetail smoothly. 

Reduced investment costs 

Fast and reliable exchange of data and 

information is a decisive benefit. For 

the Eastern Annex, this was achieved 

efficiently using the Drees & Sommer 

proprietary online ProjectCommunication 

System. As an electronic data room, 

PCS stores all facts and documents 

related to decisions, making them 

immediately available to all project 

participants. 

The experts advised the principal competently 

in particular on public contract 

award, the control of planning processes, 

and cost optimization. In this way, the 

planning team under the guidance of 

Drees & Sommer achieved investment 

savings which – with the consent of 

subsidy providers – allowed additional 

services to be realized within the 

approved budget. This made a further 

contribution to optimal patient care. 

An energy-efficient block-type thermal 

power station is achieving further 

savings in operating costs. The new 

ward building is scheduled to be opened 

in summer 2011.

CONTROLLING FOR NEW SHOPPING CENTER IN LUDWIGSHAFEN 

Investor goals optimally met: 

Rhein-Galerie meets client’s 

highest expectations 

After only two years, the Rhein-Galerie in Ludwigshafen has been completed, with 

the development of a disused site opening up the inner city to the Rhine embankment. 

Drees & Sommer supported the construction project by providing controlling services 

during both the planning and construction phases. 

56 

At the beginning of 2006 the Ludwigshafen 

City Council decided to develop 

the entire site of the former customs port 

under the motto “Return to the Rhine”. 

A shopping center was to connect central 

Ludwigshafen with the Rhine embankment, 

at the same time enhancing the 

existing range of retail outlets. The 

disused site of the former customs port 

was purchased by shopping center 

specialist ECE. Construction was undertaken 

using a cooperation model 

with ECE responsible for planning and 

coordination and Züblin as the general 

contractor. 

Controlling the construction phase 

As early as the planning phase, Union 

Investment Real Estate GmbH secured 

95 percent of the Rhein-Galerie through 

a company acquisition, and thus took 

on the role of principal. Drees & Sommer 

supported the client during the purchase 

phase by providing technical due 

diligence for the project development, 

and – prior to the start of construction – 

was commissioned to undertake 

controlling during the construction 

phase. Given the many Union Investment 

Real Estate projects successfully 

concluded by Drees & Sommer, there 

was a sound basis for further trusting 

cooperation.

CONTROLLING FOR NEW SHOPPING CENTER IN LUDWIGSHAFEN 

Support during acceptance inspections 

At the client’s request, Drees & Sommer 

paid particular attention to the quality 

of construction and provided support 

during acceptance inspections. As a 

result of this controlling, the specialists 

secured the investor a high-quality 

property that was awarded the DGNB 

Gold preliminary certificate during 

execution. The Drees & Sommer expert 

team provided consultation on sustainability 

to the client in the lead-up to the 

project. 

The design of the Rhein-Galerie met high 

ecological standards with regard to the 

drinking water and wastewater concept. 

Meltwater and rainwater is fed directly 

into the Rhine, thus returning it to the 

natural water cycle. Not only were fixtures 

with excellent water-saving ratings 

selected for sanitary facilities, but the 

entire shopping center was planned 

using ecological and sustainable 

building materials to save energy and 

reduce carbon emissions. 

The Rhein-Galerie provides the Rhine 

embankment promenade with a city 

precinct that links to the city center 

through squares, food & beverage outlets 

and leisure activities. It offers 30,000 

square meters of retail space with 130 

shops on four levels with 1.2 kilometers 

of shopfront and parking for 1,400 

vehicles. The membrane roof – with an 

area of 25,000 square meters – is a 

particularly striking feature. At night it is 

illuminated with alternating white and 

blue light. A self-cleaning Teflon coating 

ensures that the fabric roof stays clean. 

Handover to a satisfied client 

Through regular site visits, meetings 

with the client and the prime contractor, 

examination of construction related 

information, and comprehensive consulting 

provided to the principal, 

Drees & Sommer made a substantial 

contribution to ensuring that the 

handover from ECE to Union Investment 

Real Estate GmbH was completed to 

the total satisfaction of all involved. 

To round out the success, the Rhein- 

Galerie Ludwigshafen opened on 

schedule at the end of September 2010. 

With its attractive architecture, the shopping center 

integrates harmoniously with the Rhine promenade 

Drees & Sommer supervised acceptance inspections 

and, through regular site visits, contributed to the 

success of the project

GREEN BUILDING CERTIFICATION FOR FOOD STORES 

Carbon emissions from the new generation of Lidl stores is about one third lower than previous types 

Lidl pilot store 

awarded DGNB Silver 

In 2009, the Lidl discount chain presented the concept for a new sustainable 

generation of stores. Drees & Sommer energy-conservation experts were involved 

in its design. The first store was opened the same year – and in 2010 it was 

awarded the German Sustainable Building Certificate (DGNB) with a Silver rating. 

The certification process was managed by Drees & Sommer. 

The development of sustainable 

buildings is also a trend in the retail 

trade. Pioneer in this area is the Lidl 

discount chain. Drees & Sommer 

energy management experts developed 

a concept for a new generation of stores 

that are ecologically sustainable in 

operation and demonstrably cut costs. 

Overall, the concept reduces carbon 

emissions from the new buildings by 

about one third compared to previous 

buildings. 

Lidl is successfully achieving economic 

goals with the new stores, 

as Drees & Sommer costed the 

measures in such a way that the 

investment would be particularly 

quickly amortized. Lidl has also 

been quick to roll out this new 

concept: By the end of 2010, 47 

new stores were built according 

to this design. A pilot store was 

opened in Hannover in November 

2009 and was awarded the DGNB 

Silver certificate at Expo Real.

Optimized architecture and a new 

technical concept 

The new Lidl stores have improved 

thermal insulation and a more compact 

structure. The main savings are made 

in the interior. The building services 

equipment concept combines a whole 

range of effective measures. Energy 

for heating, for example, is recovered 

from the waste heat from refrigerated 

displays. 

Underfloor heating provides more 

efficient heating of large areas, while 

advanced air conditioning systems 

use less energy than before, thanks to 

heat recovery. Lighting with fluorescent 

lamps and reflectors is also highly 

efficient. This all results in a greater 

feeling of well-being for both customers 

and employees – an intended sideeffect 

of the above measures.

But Lidl and the Drees & Sommer 

consultants are not resting on their 

laurels. 

They are planning the certification 

of a so-called prototype building 

specification. All buildings built in 

accordance with this master plan 

are then automatically awarded the 

DGNB Silver certificate. In this way, 

the energy-optimized “store of the 

future” will be systematically applied 

as the sustainability guideline for 

the company.

INTERNATIONAL PROJECT MANAGEMENT FOR PHARMACEUTICAL BUILDINGS 

The LIFT production building in Rubí, Spain 

Ensuring quality and economy 

for an international player 

Drees & Sommer is supporting numerous projects 

for B. Braun Melsungen AG as the company 

continues its international growth. Whether in Peru, 

Spain, Switzerland or at home in Germany, the 

success of these construction projects is secured 

with management expertise and the right tools. 

62 

B. Braun sets the highest standards 

for the production of pharmaceuticals 

and medical products in many countries. 

And the company expects the same top 

quality when it comes to the construction 

of its factory and production buildings. 

For this reason, B. Braun commissioned 

Drees & Sommer to undertake project 

management for numerous construction, 

remodeling and extension projects. The 

key goals are to achieve the same high 

standard at each site and to ensure that 

planning and implementation meet cost, 

schedule and quality goals. 

A team of pharmaceutical experts has 

been devoted to this demanding task for 

some time. The long-term client is professionally 

supported with high levels of 

commitment, dedication and enthusiasm 

almost round the clock worldwide. 

Peru: Cost and planning check, project 

controlling and reporting 

B. Braun is building a new industrial and 

production building with a gross floor 

area of some 10,400 square meters near 

the Peruvian capital, Lima. Following 

completion of execution planning, 

B. Braun commissioned Drees & Sommer 

to undertake a review of costs and 

planning in order to have the soundest 

possible basis for budgeting. 

The cooperation between Peru, Spain 

and Germany was a special feature of 

the project: Because of the distances 

involved, it could only take place by 

telephone and using digital media 

in Spanish and English. Despite difficult 

circumstances, the building was completed 

on schedule within the budget for 

which Drees & Sommer was responsible 

at the end of June 2010. 

Spain: Project management with PCS, 

reporting and schedule management 

Drees & Sommer supported the 

project for the construction of the annex 

to the modern LIFT industrial and 

production building in Rubí, Spain, 

from the beginning of the construction 

phase. During the course of the project, 

the experts worked with the Spanish 

project team and the general planner 

to optimize planning following several 

changes to the target budget. 

The experts got up to speed on the 

project by carrying out a complete review 

of costings, while at the same time 

integrating a complete project management 

system for the already started 

project. Since then, the experts have 

been monitoring and controlling organization, 

costs and schedules, as well 

as employing the web-based Project 

CommunicationSystem (PCS). As a 

result of excellent service delivery, 

Drees & Sommer was additionally 

commissioned to undertake construction 

schedule management for the entire 

project. 

The commitment of the specialists 

paid off: The first two production lines 

will start operation on schedule in 

spring 2011, with a third following at the 

beginning of 2012. Despite extremely 

tight costings with no reserves and the 

exacting schedule, the project has 

remained within budget. 

In Lima, Drees & Sommer 

is supporting B. Braun with 

the construction of a modern 

production building

PROJECT MANAGEMENT FOR ADVANCED MEDIA HEADQUARTERS 

New SWR building: 

Economical and functional 

Stuttgart is a city with steep roads 

and many steps. Short lines of communication 

can be a distinct advantage. 

Longer distances are more of a hindrance 

in the Stuttgart basin than elsewhere, 

particularly when time is of the essence. 

Organizations that, like SWR, are scattered 

across multiple sites and which 

depend on rapid travel either by car and 

on foot lose a lot of valuable time and 

resources. What can be done? 

Well equipped for the future 

After nearly half a century of operating 

in a production building in Park Berg and 

at numerous other sites spread across 

the city, SWR has been building a new 

headquarters next to the existing Funkhaus 

(broadcasting house) in the east 

of Stuttgart. Two key goals are to be 

achieved: Consolidating the formerly 

scattered personnel at one location and 

equipping them with state-of-the-art 

media technology. 

The building combines a range of 

facilities in an area of nearly 30,000 

square meters: 480 office workplaces, 

several editorial rooms, three television 

studios, a bi-medial studio for radio 

In the media industry, hardly anything 

is as important as speed and topicality. 

Südwestrundfunk (‘Southwest Broadcasting’, 

SWR) is adhering to this principle with 

the construction of its contemporary 

multipurpose office and production facility. 

Drees & Sommer has supported the project – 

which brings all SWR employees together 

at one location – from its inception. 

and television, and underground 

parking for 150 vehicles. Test operation 

is expected to begin in autumn 2011, 

allowing radio and television programs 

to be produced there from the beginning 

of 2012. The consolidation of various 

departments in one of the most modern 

media and production facilities in 

Germany results in numerous economic 

and functional benefits for the broadcaster’s 

operations. 

Feasibility study, architect selection 

and project control 

Drees & Sommer experts were involved 

in the project from the word go. Amongst 

other things, the expert team supported 

SWR by undertaking feasibility studies 

and, building on this foundation, with 

the architect selection process. 

Through its professional project control 

during both planning and construction, 

Drees & Sommer made a substantial 

contribution to ensuring that – despite 

difficult construction conditions and 

foundation issues – the project will be 

successfully completed in 2011. SWR 

can serve its listeners and viewers even 

better in the future and everyone will 

be walking “ON AIR”.

PROJECT MANAGEMENT FOR NEW OFFICE BUILDING 

ZVO headquarters – a building that 

benefits customers and employees alike 

Openness, customer proximity and functionality – these were features the 

Zweckverband Ostholstein (ZVO, Ostholstein utilities association) wanted for its 

new headquarters. With the assistance of Drees & Sommer, these requirements 

were realized in a new building at the new location in Sierksdorf. 

Whether customers or employees, 

people have always been the focus of 

ZVO’s work. This service provider in 

the supply & disposal industry with a 

history stretching back over 80 years 

now has some 250 employees. And its 

customers are people in the Ostholstein 

region of North Germany. 

Until recently, the huge distances on 

the coast resulted in long drives between 

locations. This not only threatened to 

jeopardize customer care, but the many 

trips undertaken by employees also led 

to unnecessary environmental pollution 

and increased costs. 

Friendly user-oriented new building: 

The functionality of the new ZVO headquarters 

is partially the result of well-thought-out 

operational zoning 

The new central headquarters has 

clear benefits 

The realization in 2006 that the 

situation had to be improved formed 

the basis for the development. Some 

four years later, the proud result stands 

in the Neustädter Bucht industrial 

park: the company’s modern, highly 

functional new headquarters. 

The complex on the new premises 

comprises two dovetailed elements. 

These accommodate rooms for various 

uses, including offices, laboratories, 

storerooms and workshops. All ZVO 

employees relocated here in 2010. The 

architecture is generous without being 

ostentatious. The interior is clearly 

thought through down to the last detail 

of office fitout – and it is immediately 

apparent that the building is designed 

to promote open communication.

PROJECT MANAGEMENT FOR NEW OFFICE BUILDING 

Sound support from site analysis to 

handover 

Drees & Sommer consulted with the 

principal right from the initial project 

idea. As part of the location optimization 

analysis, the managers first examined 

the profitability of the project with regard 

to investment, operational and labor 

costs. Then various realization options 

were weighed against each other, 

including, for example, the suitability of 

adopting a Public private partnership 

approach for the planned new building. 

Organization consulting cuts costs 

Even before the start of actual planning, 

Drees & Sommer organizational consultants 

were able to cut the investment 

cost by optimizing space requirements by 

20 percent through early energy 

management and Facility management 

consulting. The basis for this included 

the development of a flexible office 

concept with an open communication 

structure and minimal filing areas. 

At the same time, a digital document 

management system was introduced 

in close cooperation with the ZVO 

employees. 

During the implementation phase, 

Drees & Sommer managers focused 

primarily on adherence to cost, schedule 

and quality goals and smooth progress 

of construction. And they were successful: 

All key parameters were adhered 

to and on March 24, 2010 the building 

was handed over to the principal 

following several years of planning 

and construction. It is no accident that, 

until today, the ZVO is pleased with 

its new headquarters that combines 

economy, sustainability and a high 

degree of functionality. It is a reflection 

of the company’s philosophy and its 

future course.

PPP INVITATION TO TENDER AND MANAGEMENT FOR MULTIPURPOSE HALL 

ratiopharm arena: 

plan, build and operate 

Drees & Sommer is coordinating the construction of a new multipurpose hall in 

Neu-Ulm. Built using the Public Private Partnership (PPP) model, the experts 

supported the cities of Ulm and Neu-Ulm with the invitation to tender, planning, 

construction and operation, as well as the construction phase itself. 

For over twenty years, the cities had 

talked about having a joint function hall, 

and in 2009 the two councils decided – 

with an overwhelming majority – that 

the new multipurpose facility would be 

built on the Volksfestplatz (festival 

ground). As the result of a change in 

league requirements, the old Kuhberghalle 

was no longer suitable as a venue 

for basketball games. And in addition 

to ball games, the new venue is 

designed to host concerts, shows and 

cultural events for the whole of greater 

Ulm and Neu-Ulm. 

PPP consulting with detailed analysis 

Together with the two city councils, 

Drees & Sommer developed the idea 

for the construction of the hall using 

the Public Private Partnership (PPP) 

model. The building was realized in a 

cooperative venture between local 

government and a private partner. 

The parameters for the bidders were 

maximum construction costs totaling 

€20.1 million net for the arena, operation 

over a period of at least 20 years and 

a maximum operating cost subsidy of 

€545,000 per year from the cities. The 

Drees & Sommer experts carried out a 

market survey and undertook a neutral 

examination of requirements. This 

type of analysis of parameters shows 

whether and to what degree a PPP is 

actually suitable. The city councils 

of Ulm and Neu-Ulm attached great 

importance to ownership of the building 

and to being able to influence its 

operation. 

Construction work on the new arena 

started mid 2010. Drees & Sommer undertook 

project control during execution. 

Holistic support as project controller 

The Drees & Sommer team presented 

the interim and final results to various 

bodies and ensured that the milestone 

plan was within the agreed timeframe. 

At the end of 2009, the contract for the 

planning, construction and operation 

of the building for a period of at least 

20 years was awarded to the Max Bögl 

Group. The design for the building was 

developed by Architektur Concept. 

Construction work on the arena started 

in mid 2010, with Drees & Sommer 

undertaking project control throughout 

execution. Tracking of cost increases 

and cost cuts allowed additional features 

to be realized, sometimes at no extra 

cost. As a result of the PPP process, Max 

Bögl, as long-term operator of the facility, 

has a great interest in ensuring high-

Federal Basketball League’s three largest. It will 

also be used for cultural events. 

quality and functional implementation 

of the project. Strict implementation 

requirements – such as a passive house 

standard applying to several building 

components, connection to district 

heating, and the inclusion of a photovoltaic 

system will ensure operational 

and energy cost savings. 

Multipurpose hall for two cities 

The new multipurpose hall will accommodate 

up to 9,000 spectators and, once 

completed in December 2011, will be 

one of the German Federal Basketball 

League’s three largest venues. The cost 

for the project totals €27.6 million net. 

The building includes integrated theatre 

boxes, and the foyer and the business 

club can be used as separate venues. 

The German ratiopharm Ulm team – 

member of the Federal Basketball 

League – is anchor tenant of the hall. 

Until the official naming, the hall had the 

working title ‘Multipurpose Hall Ulm/ 

Neu-Ulm’, indicating the close cooperation 

between the two cities. As a long-term 

principal sponsor and name sponsor, 

the pharmaceutical company ratiopharm 

secured naming rights for the multipurpose 

hall. Since July 2010 it is now 

officially known as the ‘ratiopharm 

arena’, reflecting the close links between 

the club and the company. 

The opening is scheduled for December 6, 

2011. Thanks to the trusting cooperation 

and optimal consulting during the 

tendering process and project execution, 

Drees & Sommer has already been 

awarded follow-up projects in Ulm.

GENERAL PLANNING FOR A NEW HIGH-RISE 

“No worries” package 

for complex requirements 

F. Hoffmann-La Roche – a global player in pharmaceuticals – 

is consolidating its headquarters in Basel which – up to now – 

has been scattered across several locations in the city. 

A 178-meter office high-rise is being built based on plans 

developed by Herzog & de Meuron. Drees & Sommer has been 

commissioned to undertake general planning of what will be 

Switzerland’s highest building. 

With this striking building, Roche is 

identifying with its ‘home town’ of Basel. 

The building, shaped like a right-angled 

triangle, offers an auditorium, external 

terraces and communication zones 

on 41 levels, and accommodates some 

2,000 office workplaces. 

With the construction of the high-rise – 

known as Bau 1 (Building 1) – the 

world’s largest biotechnology company 

is investing in its employees while at the 

same time continuing the architectural 

tradition for its headquarters by erecting 

a building that is at once bold and 

functional. 

“We are delighted work on this 

exciting project can now start.” 

Matthias M. Baltisberger, 

Manager, Roche Basel 

74 75

GENERAL PLANNING FOR A NEW HIGH-RISE 

Improving workplace quality, 

minimizing land use 

Numerous compelling arguments spoke 

in favor of consolidating the Basel 

offices: Close proximity promotes 

communication – a factor of key importance 

to a research-oriented organization. 

And a modern new building allows for 

a pleasant working environment that 

motivates employees and promotes 

creativity. Added to which, it also makes 

more efficient use of space. Together 

with advanced building operation, this 

can save the company huge amounts 

over many years. 

Basel, on the other hand, benefits from 

a reduction in traffic in and through the 

city and at the same time – an important 

factor in Switzerland – it prevents further 

land use in the surrounding area. In 

addition, Basel’s image will clearly benefit 

from the addition of an iconic architectural 

attraction that will define the city’s future 

silhouette. 

Professional management of complexity 

The client required independent project 

management experts to manage the 

complexity of such an extensive construction 

project. But the experts were 

not only to have specialist know-how, 

but also to have sufficient personnel 

resources and a suitable range of tools 

at their disposal. Drees & Sommer had 

previously supported the principal 

successfully. With its general planning 

service, the company offers a “No 

worries” package to ensure the rapid, 

reliable and economical execution of all 

aspects of major construction projects. 

In addition to the conventional 

management services such as project 

organization, schedule & cost controlling, 

risk & quality management, 

requirements management, documentation 

management and reporting, 

general planning also covers the 

coordination and specialist management 

of all project participants. In 

addition, Drees & Sommer is undertaking 

planning of facade technology, building 

services equipment and structural 

design. 

As a ‘temporary construction department’, 

the professionals substantially 

reduced the burden on the principal. 

Following the successful meeting of key 

milestones in the planning process for 

the client in 2010, the City of Basel’s 

Building Inspectorate granted building 

approval in February 2011. The 

people of Basel as well as Roche and 

Drees & Sommer employees are all 

looking forward to the completion of 

this unique project.

PROJECT MANAGEMENT AND ON-SITE COMPETENCE FOR NEW FACTORY 

Major Mercedes-Benz project 

in Hungary on the home straight 

Mercedes-Benz is building a new €800 million factory in Kecskemét, Hungary. New-generation 

compact cars are scheduled to start rolling off the assembly line there from the beginning of 2012. 

Drees & Sommer supported the client during the planning phase and an expert team is now on 

site controlling the realization of this ambitious project. 

78 

A close relationship between Mercedes- 

Benz and Drees & Sommer experts, 

developed over many years, gave the 

client the confidence to award this 

contract in 2008. Drees & Sommer has 

a proven track record of expertise with 

numerous projects in the auto industry 

and years of experience in industrial 

construction. And with a regional office 

in Hungary, Drees & Sommer also has 

the required local expertise. The in-house 

Hungarian specialists are not only fully 

conversant with the special approval 

requirements in the country, but are 

also acting as qualified construction 

engineering interpreters for the duration 

of the project. 

Project management competence in 

Sindelfingen and Hungary 

The Drees & Sommer expert team 

has already provided support to the 

Mercedes-Benz team at its Sindelfingen 

plant. There, at a very early stage of 

the project in 2008, they worked with 

Mercedes-Benz factory planners to 

develop the layout of the new factory 

and to coordinate material flows with 

actual production flow, thus making a 

substantial contribution to advancing 

the planning. 

Since 2009 the Drees & Sommer 

experts for automobile and industrial 

construction have been supporting 

Mercedes-Benz employees with the 

construction of the new factory in 

Hungary. Having inhouse specialists 

on site has allowed optimum cooperation 

between Hungarian and 

German colleagues. In this way, 

Drees & Sommer has already helped 

with approvals, coordination with 

numerous public authorities, and prequalification 

of construction companies. 

Sophisticated industrial architecture under a shining 

star: the paint shop with body buffer and the central 

administrative building 

79

PROJECT MANAGEMENT AND ON-SITE COMPETENCE FOR NEW FACTORY 

Budget, schedule and quality requirements 

met 

The project parameters were demanding, 

including a tight schedule. As Hungary 

imposes mandatory quality standards, 

the entire complex also had to meet the 

requirements of sophisticated industrial 

architecture. This was achieved through 

the committed participation of the 

architects involved. 

The future production plant comprises 

a pressing plant, weld shop including 

logistics halls, a building for surface 

treatment (paintshop) with body buffer, 

and an assembly hall including logistics, 

and associated industrial parks for 

suppliers. A central building complete 

with outbuildings accommodates the 

administration employees. The construction 

site has a total area of approx. 

180 hectares, the entire site totals 

441 hectares. The gross floor area of 

the project totals more than 300,000 

square meters. The factory is designed 

for the production of more than 100,000 

units annually and will employ some 

2,500 people when completed. 

Preparations ensure timely completion 

Careful preparation of the construction 

site with sophisticated site logistics, 

detailed construction process simulation 

and strict time management were key 

requirements for completion in the 

construction period of 24 months 

(six months for preparatory measures 

such as land leveling and 18 months 

construction time). Drees & Sommer 

also supported the client by providing 

its ProjectCommunicationSystem (PCS) 

and CostMonitor (CoMo) tools. These 

two web-based tools allow the principal 

and all involved in the project to access 

current cost and schedule information 

at any time. 

Daily updates to information and close 

monitoring by Drees & Sommer will 

ensure that the installation of plant and 

equipment starts on schedule and that 

the planned Start of Production (SOP) is 

met. The first cars will leave the assembly 

line in Kecskemét in the first quarter of 

2012 to be handed over to their new 

owners.
