10 PavementsPavements are designed specifically for theexpected load conditions throughout thedesign life of the road. Pavement types varyfrom flexible pavements through semi-rigidto rigid concrete pavements.COWI designs pavements that meet therequirements of each specific load condition.We combine state-of-the-art methodology andexpertise to reach sustainable and cost-effectivesolutions. At the same time, we are dedicatedto the utilisation of available technology andmaterials, always observing environmentalrequirements.Paved areas may be subjected to a widevariety of loads. From rubber-tyre vehiclesmoving at high to moderate speeds, throughforklifts with solid wheels of high stiffness tostationary loads created by parked vehicles orstacked containers.Pavement repair in Zambia on the590 km Lusaka-Mongu road,traversing the Kafue National Park– the largest game reserve in AfricaServices• Surveys• Pavement condition studies• Pavement analysis and modelling• Pavement design- Flexible and semi-rigid pavements- Rigid pavements- Low-noise pavements- Special pavements, e.g. container terminals- Innovative pavements• Recycling• Material investigations for pavements• Material engineering for pavements• Pavement maintenanceCompaction machinery atwork on the Dar-Mlandiziroad, Tanzania• Environmental impact assessment (EIA)• Economic analysis• Quality management

16 Traffic terminalsCOWI has wide experience with ferry terminals,container terminals, bus and trainterminals, airport terminals, distributionterminals for land transport and parkingterminals. We have designed a large numberof such terminals in co-operation witharchitects and landscape architects.Private and public transportFerry harbours, large bus and train stations,and airport terminals are locations where theinterchange between private and public transporttakes place. It is important that the changecan take place rapidly and safely, and with theleast possible disruption for the passengers.Safe access, adequate parking facilities, logicallocation of ticketing facilities, short walkingdistances and easy-to-read time schedule informationare key words for the planning anddesign of terminals.Services• Master plans• Flow condition analyses• Demand modelling and simulation• Functional and detailed design• Compact terminal management• Real time information systems• Feasibility studiesBus terminal in Gladsaxe, Denmark.

20 TANZAM highway, TanzaniaIn 2005, COWI was awarded a contract forthe consulting services for the design and theconstruction supervision of an approximately218 km long section of TANZAM highwayThe TANZAM highway is approximately921 km long and is designated as Trunk RoadT1 in the Tanzanian road network. This majorhighway links the port of Dar es Salaam to theland-locked countries of Zambia, Malawi andthe Democratic Republic of Congo. The roadlinks important national and internationaltourist destinations located along the TAN-ZAM corridor, including Mikumi NationalPark, Udzungwa Mountain Forests and GamePark, and Ruaha National Park.The Government of Tanzania has obtainedfinancial support from Denmark, in the formof mixed credit financing, for part of theTANZAM highway rehabilitation programmecurrently under preparation. The road section,which receives high priority within the government’sroad rehabilitation programme, is a 225km road-section between Iyovi and Mafinga.Apart from a 7 km section, the road has notreceived major repairs since construction in1973, and the pavement is in urgent need ofrehabilitation.Phase I includes design review, detailedengineering design and tendering. Phase IIincludes supervision of construction work. Theproject also comprises environmental andsocial assessments.Phase I is expected to be completed in June2007 and Phase II in June 2011.Services• Detailed design• Design review• Tender assistance• Supervision• Traffic safety improvement• Environmental assessment• Social impact assessmentProject period2005 - 2011ClientTanzania National Roads AgencyTANROADS, Tanzania

22 Motorway Ring 3, DenmarkThe motorway Ring 3 project expands thefour-lane heavily trafficked ringroad aroundCopenhagen to a six-lane motorway. Themotorway passes through densely populatedsuburbs.During the construction period, the normaltraffic must be serviced by 4 lanes, except forshorter periods of time during weekends andevenings/nights. This requires extensiveplanning of:• Information to be provided to roadusers• The sequence of road works for lanes andsections• Detours• Construction works logistics• Temporary road marking and signalsDue to limited land area, the project will includeextensive use of retaining walls. Further-more, noise barriers shall be established alongthe total length of the project road.COWI’s services include geotechnicalinvestigations, preparation of an environmentalmanagement plan, inventory of adjacentfacilities, land acquisition, detailed design ofthe road section and a large number of gradeseparated interchanges, pedestrian bridges andunderpasses, retaining walls, noise barriers andscreens, road lighting and road furniture suchas signal signs and road marking.COWI is responsible for the master planningof construction works and contractor’s officesand facilities, utility relocation and trafficmanagement.COWI is preparing tender documents forfour contract packages and assisting the RoadDirectorate in the tendering process and thesupervision of construction works.Services• Advisory and expert assistance• Planning, studies andevaluation• Surveys and investigations• Design• Tendering and contracting• Construction supervision• Quality managementProject period2003 - ongoingClientDanish Road Directorate,Denmark
