Tarchitect, to redesign the <strong>Athens</strong> Olympic<br />
HE Organising Committee <strong>for</strong> the Olympic<br />
Games <strong>Athens</strong> <strong>2004</strong>, in a joint ef<strong>for</strong>t with the<br />
Ministry of Culture in Greece, chose Dr<br />
Santiago Calatrava, the renowned Spanish<br />
Sports Complex (OAKA) and to carry out a series of other<br />
architectural works in the city of <strong>Athens</strong>.<br />
Combining, within a modern context, the<br />
environment, history and culture of Greece, particularly<br />
the spirit of the Olympic movement, Dr Calatrava has<br />
created a work of art that has left a permanent mark on<br />
contemporary <strong>Athens</strong>.<br />
Perhaps the identity of both the <strong>2004</strong> Games and the<br />
city of <strong>Athens</strong> is best reflected in the design OAKA.<br />
Key features of Dr Calatrava’s design include the<br />
suspended arches which partially cover the Olympic<br />
Stadium, the Velodrome and the entrances leading to the<br />

OAKA area. A semicircle is created between the<br />
competition venues, providing the same cover <strong>for</strong> the<br />
sponsors’ hospitality venue, the restaurants and the shops<br />
at the Games.<br />
In the post-Olympic era, the same area can host major<br />
events and exhibitions.<br />
Further, the Tower of the Olympic Flame was placed<br />
in a central square, in such a way that it was visible from<br />
each and every competition venue.<br />
Dr Calatrava’s skill in bringing design and<br />
engineering elements together in an innovative and<br />
creative way is reflected in his design <strong>for</strong> the OAKA.<br />
The paved central axis (the boulevard) which runs<br />
from east to west, provides a direct connection to the<br />
various Olympic venues.<br />
Suspended arched roofs partially cover the Olympic<br />
Stadium (the location <strong>for</strong> the opening and closing<br />
ceremonies, track and field events and the men’s soccer<br />
final) and the entrances, and fully cover the Velodrome<br />
(the location <strong>for</strong> the indoor cycling events). At the Arcade,<br />
curved shell structured steel arches and top cladding<br />
provided shade <strong>for</strong> spectators while allowing sunlight<br />
in.<br />
Indigenous vegetation was planted inside and outside<br />
the OAKA, while decorative water pools with light blue<br />
surfaces illuminated at night, enhanced the natural,<br />
relaxed atmosphere of the Games.<br />

The Olympic Stadium<br />
In accordance with the architectural study per<strong>for</strong>med by<br />
Santiago Calatrava, the newly built roof partially covers<br />
the Olympic Stadium, mainly the terraces, over a total<br />
area of 25,000 sq m.<br />
The bearing construction is made of two double steel<br />
arcs which are positioned at the same height in pairs, and<br />
connected with extended cables. A system of diagonal<br />
connectors further strengthens the structure.<br />
The construction is completed with transverse girders<br />
which are connected to the lower arc and <strong>for</strong>m a grid on<br />
which polycarbonate was installed.<br />
The Velodrome<br />
The Olympic Velodrome is fully covered with a structure<br />
similar to the roof of the Olympic Stadium, with a steel<br />
bearing structure, the central zone of which is covered<br />
with solar controlling laminated glass and the rest with<br />
aluminium panels. The inner surface of the roof is lined<br />
with wooden panels.<br />
The Entrance Canopies<br />
The entrance canopies provided visitors with their first<br />
and final impressions of the complex. Spectators were<br />
able to clearly identify the Sports Complex OAKA by its<br />
glazed canopies which consist of steel structures<br />
supported by steel arches and topped with laminated<br />
glass.<br />
The Agora<br />
The Agora is a multi-purpose space which dominates the<br />
OAKA public areas, and comprises two main areas - the<br />
square and the arched promenade which provides shade<br />
<strong>for</strong> the public and at the same time, acts as a connective<br />
element between venues.<br />
The arched promenade consists of a series of steel<br />
arches, between which white wooden beams are placed.<br />
The roof provides shade and creates a pleasant<br />
atmosphere.<br />
The Wall of Nations<br />
The Wall of Nations is a huge sculptural creation made<br />
from steel tubes. These are motorised and can move in a<br />
wave-like manner. RnF<br />

A polycarbonate roof <strong>for</strong> the Olympic Stadium<br />
THE Olympic Stadium in <strong>Athens</strong>, named after Spyridon Louis, the Greek<br />
winner of the Marathon at the first modern Olympic Games in <strong>Athens</strong> in<br />
1896, was the venue of the Opening and Closing Ceremonies, all the track<br />
and field events and the men’s soccer final, at the <strong>2004</strong> Olympic Games.<br />
The roof of the arena, called the Calatrava Dome, can already claim three<br />
world records. It is not only the biggest stadium roof in the world, it is also<br />
the largest transparent roof ever built. Thirdly, it is the biggest roof ever to<br />
have been placed on top of a stadium after the stadium was completed.<br />
The roof sections are made of solid, highly transparent plastic sheets of<br />
MAKROLON polycarbonate from Bayer MaterialScience AG. The bluish<br />
shining panels provide <strong>for</strong> a friendly, open and bright atmosphere in the<br />
arena, and made it possible <strong>for</strong> the spectators to gaze up into the Greek<br />
summer sky.<br />
The roof is a dynamic suspension structure, defined by two metal arches,<br />
each 300 m long, with their apex rising to a height of 78 m. The arches span<br />
the stadium in the longitudinal direction and each carry a dome suspended<br />
on double-arch supports. In total, the roof structure weighs 17,000 tons,<br />
covers an area of nearly 25,000 sq m and can protect up to 75,000 spectators<br />
from direct sunshine and rain.<br />
Wire cables are connected to the two large metal arches, and it is to these<br />
that the 12 mm thick, nearly 5 m long and 1 m wide polycarbonate sheets<br />
are fixed. Sheets made of MAKROLON were chosen not only because of its<br />
high transparency but also on account of its lower weight when compared<br />
with that of glass. The sheets weigh just 14.4 kg/sq m. The favourable statics<br />
provided the architect with greater design scope.<br />
A special additive in the plastic kept the spectators cool despite the<br />
summer heat. This additive reflects the majority of the radiant heat from<br />
natural sunlight, but still allows the visible part of the light to pass through.<br />
As a result, the air mass in the stadium did not heat up as much. Another<br />
advantage of the plastic sheets, which have additionally been given a<br />
scratchproof finish, is their machinability. They can be sawed, drilled and<br />
cut without any problem. They do not break, which, together with their<br />
low weight, made handling during assembly much easier.<br />
Equally impressive was the procedure used <strong>for</strong> the construction of the<br />
stadium. So as not to interrupt the building work, the two halves of the<br />
roof were assembled separately next to the stadium. Once the main bulk of<br />
the work in the stadium had been concluded, the two 8,500 ton structures<br />
were each manoeuvred hydraulically on to the stadium on sliding blocks,<br />
using a special track-mounted system. Finally, the polycarbonate sheets were<br />
bolted into place. RnF<br />

<strong>Roof</strong>ing <strong>for</strong> the Stadium of<br />
Peace and Friendship<br />
THE Stadium of Peace and Friendship is located about<br />
25 km from the Olympic Village, in the Faliro Coastal<br />
Zone Olympic Complex, south of <strong>Athens</strong>.<br />
The venue <strong>for</strong> the volleyball matches at the <strong>2004</strong><br />
Olympic Games has a concave-shaped roof that offered<br />
protection to the approximately 14,000 spectators and<br />
players, from the extreme summer heat.<br />
Further, since the roof was supported solely by pillars<br />
at its perimeter, television viewers and spectators alike,<br />
were provided with an unobstructed view of the<br />
volleyball court.<br />
However, since the 35 m high stadium is located<br />
directly at the harbour, it is subject to the torrid heat in<br />
summer and the near-freezing temperatures in winter,<br />
varying wind strengths and salt-laden air.<br />
Sarnafil TS 77-15 - RAL 7040, a flexible polyolefin<br />
from Sarnafil, was used in the refurbishment of the<br />
existing roof, due to its special <strong>for</strong>mulation and the fact<br />
that it does not contain any plasticiser. The product has<br />
good chemical resistance, even at higher temperatures.<br />
These characteristics were decisive <strong>for</strong> the Greek<br />
contractors, since protection of the stadium needed to<br />
be long-term. Sarnafil-trained installers passed on<br />
expertise and knowledge to their Greek counterparts, a<br />
step that was crucial to the completion of the enormous<br />
installation. Together, they covered a surface as large as<br />
two soccer pitches.<br />
Sarnafil was also involved in building the<br />
Beach Volleyball Centre and other stadiums <strong>for</strong> the<br />
Games. RnF<br />

The use of stone in curtain walls<br />
[This is an edited excerpt from a publication produced by Internazionale Marmi e Macchine<br />
Carrara SpA (IMM). Well-known all over the world <strong>for</strong> the promotion of marble and other<br />
stone materials, IMM has, over the last few years, expanded its range of activities. The<br />
company’s objective is to acquaint people with the qualities of stone and all its possible uses].<br />
Introduction<br />
The use of thin stone in curtain wall systems<br />
is becoming more widespread in Europe.<br />
Aside from their traditional structural<br />
function, stone materials are now being recognized<br />
<strong>for</strong> characteristics which compare<br />
favourably with those of many other building<br />
materials used <strong>for</strong> cladding purposes.<br />
These include aesthetic qualities; the ability<br />
of the stone to act as a barrier to prevent<br />
atmospheric and polluting elements from<br />
entering the internal environment; the minimal<br />
requirement <strong>for</strong> maintenance or renovation;<br />
their capacity to increase the degree<br />
of internal com<strong>for</strong>t, thanks to the possibility<br />
of creating ventilated curtain wall systems;<br />
and their ability to provide greater<br />
sound reduction in lightweight cladding<br />
systems, due to the mass of the materials.<br />
In order to exploit the above characteristics<br />
and maintain adequate safety levels, especially<br />
in the use of thin stone <strong>for</strong> large<br />
buildings subjected to adverse environmental<br />
conditions, the important considerations<br />
include the correct choice of stone, the accurate<br />
design of stone fixing systems, and<br />
the accurate installation of stone.<br />
Criteria in the choice of stone<br />
<strong>for</strong> cladding<br />
As the use of stone <strong>for</strong> cladding purposes<br />
is a solution <strong>for</strong> the lifespan of the<br />
building, the choice of the stone should<br />
be on the basis of technical and design<br />
aspects. These apply both generally and<br />
in the specific case of curtain wall systems.<br />
Architectural and aesthetic factors will<br />
determine the initial selection of the stone.<br />
These are dependent upon the vein<br />
patterns and/or grains; the extensive<br />
colour spectra; the proposed cladding<br />
layout which divides units into various<br />
shapes and sizes; and the surface finishes<br />
which best enhance the inherent aesthetic<br />
qualities of the cladding.<br />
The main factors determining the ultimate<br />
choice of stone include the production<br />
technology available <strong>for</strong> processing stones,<br />
the chemical-physical properties of the<br />
stones and their suitability under the environmental<br />
conditions at the location of the<br />
project, the mechanical properties of the<br />
stones and whether they will enable the material<br />
to withstand the stresses caused by the<br />
load conditions and the fixing systems used,<br />
and the total cost of the cladding.<br />
Stone fixing systems<br />
After completing the theoretical and practical<br />
tests to assess the quality and chemicalphysical-mechanical<br />
properties of the stone<br />
materials selected, and after taking into account<br />
the architectural design of the cladding<br />
and the environmental and loading<br />
conditions, it is necessary to select the most<br />
suitable stone fixing system.<br />
This involves the study of the design and<br />
distribution of the various notches possible,<br />
to accommodate the mechanical fixing elements<br />
in the stone units.<br />
In addition to the mechanical aspects, the<br />
fixing system depends on the cladding construction.<br />
If the cladding system uses trussbacked<br />
panels, a decision must be made as<br />
to whether or not it is better to fix the back<br />
of the stone slabs or their edges to the truss,<br />
depending on whether the truss is prefabricated<br />
on a horizontal or vertical plane.<br />
If the prefabricated panels are to be transported<br />
or handled in a position that is different<br />
from their position on the building,<br />
the fixing system must be able to compensate<br />
<strong>for</strong> such handling, or extra fixing elements<br />
should be used <strong>for</strong> this purpose.<br />
The replacement of stone units, where<br />
necessary, is also a consideration. Last, but<br />
not least in the order of importance, is the<br />
cost of the fixing system.<br />
There are two main types of fixing systems<br />
- isostatic and hyperstatic. In the<br />
isostatic system, the stone units are fixed<br />
at very few points, such that it is sufficient<br />
to guarantee the statics. This is the classical<br />
system with four pins inserted into<br />
four holes positioned on two opposing<br />
sides of rectangular panels. Owing to inaccuracies<br />
in the manufacture and installation<br />
of the material, only three out of the<br />
four pins work at any one time, except<br />
when the stone elements and the main<br />
support structure undergo great de<strong>for</strong>mations.<br />
Under the hyperstatic system, the<br />
stone units are fixed to the main structure<br />
using numerous fixing points on the reverse<br />
side of the units, using continuous<br />
profiles fixed at the edges or by gluing the<br />
units to the back support, as in the application<br />
of very thin stone on to panels in a<br />
honeycomb structure.<br />
The main difference between the two<br />
types of fixing, lies in their static behaviour.<br />
In the isostatic system defined by ‘local fixing’,<br />
the design of the stone units and the<br />
metal fixing elements must take into account<br />
the fact that if a fixing point fails, then the<br />
stone unit may detach itself from the supporting<br />
structure and fail. This may require<br />
the use of thicker panels or even the application<br />
of a rein<strong>for</strong>cement to the reverse side<br />
of the panels, which comes into play if the<br />
panels break. This fixing system makes the<br />
stone units independent of the supporting<br />
structure which is de<strong>for</strong>med by the external<br />
<strong>for</strong>ces (loads, temperature variations and<br />
other differentials). On the other hand, in the<br />
hyperstatic system defined by ‘spread fixing’,<br />
where the stone panels are fixed at numerous<br />
points, it may be possible to prevent<br />
the panels from falling, if they break. This<br />
system permits the use of thinner panels but<br />
they could then become de<strong>for</strong>med in the<br />
same way as the supporting structure.<br />
Safety in the application of stone<br />
materials <strong>for</strong> cladding<br />
The use of stone materials <strong>for</strong> cladding<br />
purposes, from the point of view of safety,<br />
is partly determined by the static and dynamic<br />
loads applied, the consequent internal<br />
stress conditions, the reaction of<br />
stone materials to environmental conditions,<br />
and the mechanical resistance to<br />
stone, and partly determined by the professional<br />
expertise employed during the<br />
design of the fixing systems, the production<br />
processes used on the stone, and the<br />
installation of the materials.<br />
In order to maintain the necessary<br />
safety levels, while still respecting the<br />
project requirements, it is essential to bear<br />
in mind the factors directly concerning the<br />
stone material itself, the fixing system and<br />
the installation. The uncertainty regarding<br />
the loading conditions has practically been<br />
eliminated by the norms which impose<br />
much greater loads than those which occur<br />
in reality and by tests such as those<br />
conducted in the wind tunnel. The uncertainty<br />
regarding the internal stress of stone<br />
materials is minimised by very accurate<br />
structural analysis carried out with the aid<br />
of sophisticated computer programs.<br />
As the results of surveys carried out on<br />
a number of buildings in the US have<br />
shown, the main causes <strong>for</strong> the collapse of<br />
stone elements in curtain wall systems are<br />
not directy linked to the inherent mechanical<br />
properties of the stone. They are due,<br />
rather, to the corrosive agents present in the<br />
environment; the unsuitable design of the<br />
fixing systems (as a result of not fully taking<br />
into account the mechanical properties<br />
of the stone around the fixing points); the<br />
inexactness in the cutting of the stone elements,<br />
so great sometimes, that the resistance<br />
around the fixing points is reduced, as<br />
in the case of oversized holes to accommodate<br />
metal fixing pins with axes that do not<br />
respect the project guidelines; the technological<br />
processes which cause micro-cracks<br />
in the material, thereby weakening it; and<br />
inadequate installation by workers who do<br />
not possess the required skills.<br />
All these factors can be checked by<br />
closely examining the behaviour of the materials<br />
selected, in similar projects and under<br />
similar conditions, and by running a<br />
series of tests on the materials, both be<strong>for</strong>e<br />
the start of production and during production.<br />
These tests are even more important<br />
<strong>for</strong> new materials as it is necessary to verify<br />
their suitability and the limits <strong>for</strong> their application<br />
in curtain wall systems. An even<br />
more effective way of controlling such factors,<br />
is by carrying out quality control procedures,<br />
both at the production and installation<br />
stages, and developing the ‘fail-safe’or<br />
‘safe-life’ design criteria on the basis of the<br />
fixing system chosen.<br />
Fail-safe systems involve a high degree<br />
of hyperstaticity and prevent the total collapse<br />
of the stone elements in the event of<br />
breakage, by keeping them fixed to the support.<br />
Moreover, it is possible to discover and<br />
replace broken stone elements during normal<br />
maintenance operations (cleaning). In<br />
the case of safe-life systems that are mainly<br />
adopted in isostatic systems, the fixing systems<br />
are designed to exclude any breakage<br />
of the systems themselves or of the stone<br />
elements. This makes the cladding as longlasting<br />
as the building itself.<br />
Safety criteria<br />
Safety criteria in the use of curtain wall<br />
systems are of paramount importance if<br />
designers are to be convinced to use stone<br />
in preference to other materials. The absence<br />
of complete in<strong>for</strong>mation regarding<br />
the chemical-physical-mechanical properties<br />
of stone materials (available <strong>for</strong> industrial<br />
products) tends to dissuade many<br />
designers from specifying their use.<br />
Un<strong>for</strong>tunately there are no current<br />
laws to establish minimum safety standards<br />
on the basis of the data available regarding<br />
the behaviour of stone materials.<br />
There are no ‘resistance criteria’ <strong>for</strong><br />
stone materials, in order to calculate the<br />
ideal stress, or the breakage point, and to<br />
compare it to an allowable stress taken<br />
from the results of tests on the materials.<br />
What actually happens is that either<br />
the designer or whoever draws up the<br />
project specifications, or the technical adviser<br />
on the end-use, has to determine not<br />
only the ultimate stress but also the acceptable<br />
one. The result is that the same project<br />
conditions can generate a variety of different<br />
safety factors and analysis criteria,<br />
based on the results of the tests.<br />
One answer to this is the ‘stone safety<br />
criteria’. As far as resistance is concerned,<br />
to calculate the ultimate stress, reference<br />
is made to the Huber-Von Mises criterion,<br />
but in some cases involving shear stress,<br />
this proves to be unfavourable.<br />
For example, marble’s ultimate shear<br />
strength, when cut, can even be double its<br />
tensile stress, and so here, HV Mises’s<br />
theory could be replaced by Rankine’s or<br />
Mohr’s, both of which are more suitable<br />
<strong>for</strong> materials with limited plastic properties.<br />
As regards the definition of the permissible<br />
stress, reference is made to the<br />
normal distribution of probability, and in<br />
accordance with the current rule by which<br />
it is governed, the average value and the<br />
standard deviation are calculated, on the<br />
basis of the results of the tests referring to<br />
the resistance of the stone material. In this<br />
way, the k values are defined, depending<br />
on the stress fractile, the number of results<br />
available and the safety factor laid down<br />
by the project specifications. The safety<br />
factors which differ according to whether<br />
they refer to the overall resistance of the<br />
stone element or just to the resistance<br />
around the fixing points, are given a wide<br />
range of variability. They can however be<br />
given minimum values, close to those<br />
under existing regulations governing<br />
usual building materials, if quality control<br />
procedures are carried out during production<br />
and installation of the materials, and<br />
fixing systems are accurately designed.<br />
Design and execution aspects<br />
Curtain wall systems allow <strong>for</strong> the manufacture<br />
of prefabricated panels at the<br />
workshop. This has several advantages.<br />
It is possible to manufacture lightweight<br />
panels with a metal truss. This facilitates<br />
installation operations and the sizing<br />
of the perimeter structure of buildings,<br />
especially when they are high-rise buildings<br />
located in seismic areas. Production<br />
is more accurate as all the machines in the<br />
workshop can be made use of, in carrying<br />
out delicate operations such as the waterproof<br />
sealing of joints, and there is better<br />
quality control indoors.<br />
Manufacturing times are reduced and<br />
productivity is increased. The prefabricated<br />
panels can be made immediately after work<br />
on the main structure of the building has<br />
begun, and installed soon after, there<strong>for</strong>e<br />
anticipating the internal finishing operations.<br />
The assembly of the panels in the<br />
workshop as opposed to the building yard<br />
increases production, with the additional<br />
benefit that weather conditions do not affect<br />
the process.<br />

The above points lead to obvious economic<br />
advantages. There are other economic<br />
advantages to be gained from the fact that<br />
external scaffolding is not necessary, and less<br />
material management is required in the yard<br />
(less storage space, less handling, fewer installation<br />
workers required etc).<br />
Owing to the great progress made in the<br />
field of processing technology over the last<br />
20 years, stone materials can now be successfully<br />
used in prefabricated curtain wall<br />
systems, taking into account several design<br />
and execution aspects, including typology<br />
of panels to be used; de<strong>for</strong>mability of the<br />
support structure of the curtain wall system,<br />
based on the system used to fix the panels<br />
to the structure of the building; the prefabrication<br />
method used <strong>for</strong> the panels; the system<br />
used <strong>for</strong> fixing the stone to the panel<br />
structure; the construction tolerance with<br />
regard to the stone elements; accuracy in<br />
stone installation; and handling and transportation<br />
methods.<br />
The building technique <strong>for</strong> curtain wall<br />
systems allows <strong>for</strong> the production of very<br />
light, metallic support structures, necessary<br />
to satisfy the technical specifications of<br />
projects, which sometimes permit elastic<br />
de<strong>for</strong>mation of these structures over 1 / 250<br />
of the clear span of deflection. The very lightweight<br />
structures are generally flexible and<br />
the way they de<strong>for</strong>m, which also depends<br />
on the type of structure and the relative fixing<br />
system, is fundamental to the use of<br />
stone materials <strong>for</strong> cladding purposes.<br />
There are two basic curtain wall systems.<br />
In one, the panels are positioned vertically,<br />
from level to level, and are fixed directly on<br />
to the slab edges. In the other, the panels are<br />
arranged horizontally, from column to column,<br />
and are fixed vertically to the columns<br />
and horizontally to the columns and the<br />
floor slabs in between. The way in which<br />
the panels de<strong>for</strong>m, once they have been installed,<br />
is different in each case. In the first<br />
system, due to the action of the wind, the<br />
flexural de<strong>for</strong>mation of the mullions predominates,<br />
accompanied by differential vertical<br />
movements of one mullion compared<br />
to the adjacent ones, due to the flexure of<br />
the slabs in the vertical plane. In the second<br />
system, the flexural-torsional de<strong>for</strong>mation<br />
is more significant, due to the assymetrical<br />
distribution of the lateral fixing points.<br />
Consequently, the fixing elements can<br />
produce interaction between the panel structure<br />
and the stone elements whose flexuraltorsional<br />
rigidity, due to their size, is comparable<br />
to, if not greater than, that of the<br />
components of the metallic structure. This<br />
interaction can become so strong that it<br />
causes critical loading conditions at the<br />
stone’s fixing points.<br />
Two possible cases of this interaction are<br />
considered. The first is caused by the de<strong>for</strong>mation<br />
in a vertical direction of the frame<br />
on its plane, due to the fixing point between<br />
the frame and the slab and the flexure of the<br />
slab. The second arises from the flexural-torsional<br />
de<strong>for</strong>mation of the same frame subjected<br />
to the action of the wind.<br />
Significant stress states appear around<br />
the fixing points, whose tension values, analysing<br />
the second case, prove to be much<br />
higher than those obtained <strong>for</strong> the same<br />
stone slabs isostatically fixed to the frame.<br />
In addition, the use of stone <strong>for</strong> lightweight<br />
cladding with prefabricated panels,<br />
must take into account the prefabrication<br />
technique used, since as has already been<br />
explained previously, this determines the<br />
fixing system to adopt. Both methods are<br />
generally conditioned by the architectural<br />
design of the cladding, as sometimes, if this<br />
is particularly complicated, the stone panels<br />
cannot be positioned either horizontally<br />
or vertically, as desired.<br />
In some cases, panels can be installed<br />
only vertically because of the particular design.<br />
In the case considered, the cladding,<br />
composed of flat rectangular elements with<br />
a surface area of approximately 1.2 m and a<br />
30 mm thickness, was fixed, according to the<br />
spread fixing system on the lower and upper<br />
edges by means of metal profiles, to a<br />
sufficiently rigid frame. In this way, the<br />
frame does not show de<strong>for</strong>mation under<br />
loading conditions, to create interaction with<br />
the stone. In the case shown, cladding with<br />
a more elaborate design, was fixed using the<br />
local fixing system. It there<strong>for</strong>e determines<br />
the behaviour of the fixing points <strong>for</strong> the<br />
stone elements, to make it independent of<br />
the de<strong>for</strong>mation of the metallic support<br />
frame.<br />
The metallic frame is itself fairly flexible<br />
under the loading conditions, considering<br />
its great size, not only after the installation<br />
on the building, but also during handling,<br />
transport and lifting operations.<br />
In these building systems, the joints between<br />
the storeys, play an extremely important<br />
role, as they have to be sized to allow<br />
<strong>for</strong> the relative movements between the<br />
stone units, which are due to the elastic de<strong>for</strong>mation<br />
of the load-bearing structure and<br />
the thermal expansion of the individual<br />
units of the entire curtain wall. These joints<br />
must be both water- and air- tight and so<br />
must be sealed with a synthetic sealant<br />
which does not have an adverse effect on<br />
contact with the stone, and which has a low<br />
elasticity modulus so as not to overstrain the<br />
joint.<br />
The use of stone in prefabricated systems<br />
with metal structures requires the production<br />
of stone units to be extremely accurate<br />
given the mechanical nature of the main<br />
support frames, especially when these are<br />
composed of extruded metal pieces.<br />
This applies not only to the overall dimensions<br />
but also to the size and positioning<br />
of the notches which house the fixing<br />
elements. Finally, accurate installation is required<br />
together with effective quality control<br />
procedures. RnF<br />

FLUOROSET FP was applied as a protective coating on the Tauranga Yacht Club, New Zealand, in<br />
1991 and has proven to per<strong>for</strong>m under the aggressive marine environment in the coastal area.<br />
FLUOROSET FP is a thermosetting<br />
fluoropolymer (PVF3) powder coating<br />
designed specifically <strong>for</strong> prestigious and<br />
monumental architectural projects where<br />
long-term colour stability, remarkable gloss<br />
retention, high mar resistance, low grime<br />
pick-up, quality of coating finish and<br />
extension of life to first maintenance are top<br />
priorities. The easy-to-apply single-coat<br />
powder coating imparts good resistance to<br />
chemicals and solvents as well as mechanical<br />
properties and abrasion resistance.<br />
Manufactured by Orica Powder<br />
Coatings, a division of Orica Coatings,<br />
FLUOROSET FP has been developed as a<br />
high quality surface finish that offers longterm<br />
protection <strong>for</strong> steelworks and<br />
architectural aluminium works, which<br />
include window and door frames, panel<br />
cladding, extrusions, louvres, mullions,<br />
grilles, sunscreens, canopies and various<br />
other aluminium fittings, <strong>for</strong> commercial,<br />
residential, institutional and industrial<br />
buildings.<br />
It has been proven that FLUOROSET FP<br />
which was released in 1991, can retain its<br />
gloss and colour <strong>for</strong> many years in the severe<br />
tropical climates of Asia and under extreme<br />
UV exposure and coastal conditions as in<br />
Australia and New Zealand. FLUOROSET<br />
FP is <strong>for</strong>mulated using advanced<br />
fluoropolymer resin technology, and utilises<br />
high per<strong>for</strong>mance exterior durable<br />
pigments. This tough resilient and low<br />
maintenance coating is available in a range<br />
of aesthetic, made-to-order colours<br />
including metallic and pearlescent colours,<br />
from satin to semi-gloss finishes.<br />
FLUOROSET FP is factory-applied over<br />
a suitably pretreated aluminium substrate<br />
such as extrusions and panels. It can also be<br />
used on specially pre-primed steelworks.<br />
FLUOROSET FP uses no solvents in the<br />
manufacturing or coating process, thus<br />
contributing to environment-friendliness,<br />
and it does not pose a fire hazard.<br />
The thermosetting FLUOROSET FP<br />
powder coating is fully cross-linked during<br />
the curing process, thus resulting in a robust<br />
and hard-wearing surface coating that is<br />
suitable <strong>for</strong> use in high traffic zones such as<br />
building entrances and shopfront areas<br />
where PVF2/PVDF coating systems are<br />
often not used because of concerns of high<br />
mechanical damage. FLUOROSET FP gives<br />

FIRE safety is of fundamental importance in the<br />
design, management and operation of buildings,<br />
industrial plants and transportation systems.<br />
Regulations there<strong>for</strong>e require certain elements of the<br />
structure to be fire-resistant.<br />
With the increasing complexity of modern design<br />
and the need <strong>for</strong> greater space utilisation, designers<br />
and architects often have to make difficult<br />
compromises between design aspirations and<br />
regulatory constraints.<br />
FIRECUT FM-900 intumescent, mastic coating<br />
was developed to solve the problems relating to fire<br />
protection, whilst maintaining architectural<br />
freedom.<br />
As part of a complete intumescent system, FM-<br />
900 provides up to 2 hours of fire-resistance to<br />
structural steel with a smooth surface.<br />
When the temperature rises to 200º C, FM-900<br />
will begin to react and gradually <strong>for</strong>ms a cake-like<br />
char layer that is 100 times the initial volume. The<br />
char layer insulates against the conduction of heat,<br />
thereby protecting the steel structure.<br />
The features of FM-900 include good fireresistance,<br />
suitability <strong>for</strong> spray-on applications, ease<br />
of application, a smooth and pleasant appearance,<br />
avoidance of asbestos in its <strong>for</strong>mulation, and<br />
con<strong>for</strong>mance to international standards.<br />
With just 0.34 mm dry film thickness, FM-900 can<br />
meet the requirements of the 1 hour fire resistance<br />
rating, on a 3-sided beam.<br />
The wet film can reach 1000 microns without<br />
sagging. It is touch-dry in half an hour and harddry<br />
in 4 hours.<br />
The coating is fully cured in 7 days. The interval<br />
between coats is 4 hours by spray and 1 hour by<br />
spray and brush.<br />
After the complete application of the FM-900<br />
coating system, the surface becomes smooth and<br />
even. Further, various colours can be incorporated<br />
in the topcoat, thus combining fire-protection with<br />
aesthetics.<br />
FM-900 has been tested at Warrington Fire<br />

Focchi Singapore is involved in the Hillview Regency<br />
Condominium project. Overseas, the company<br />
participated in the construction of Brunei Mall in<br />
Brunei.<br />
For the A & A Work at Odeon Towers, the signage<br />
area uses Focchi’s spider-clamp glass system. The new<br />
podium uses the company’s proprietary Lingotto<br />
curtain wall system which has also been used in the<br />
Lingotto Exhibition Centre in Turin, Italy (designed by<br />
Renzo Piano), the Orange Telecom Centre in<br />
Darlington, UK, as well as the Mercedes Benz Centre<br />
in Rome, Italy.<br />
The Lingotto system’s main characteristic is its<br />
ability to achieve a clear height of 12 m without<br />
intermediate support, by using the bigger version of<br />
custom-made aluminium structural mullions. For<br />
Odeon Towers, the smaller Lingotto version has been<br />
used. Special aluminium castings provide the<br />
connection between the glazing and the support<br />
system. The glass is completely transparent, in order<br />
to allow the clearest view of the load-bearing structural<br />
details and the interior decor of the building. RnF<br />
Enquiry No: 10/117<br />
The new podium of Odeon Towers, Singapore (above right) uses<br />

Marble-like<br />
crystallised glass<br />
NEOPARIÉS crystallised glass was<br />
developed by Nippon Electric Glass Co<br />
Ltd after years of research. The<br />
manufacturing process involves a<br />
specialised glass crystallisation<br />
technique <strong>for</strong> producing needle-shaped<br />
crystals called wollastonite (CaO.SiO 2<br />
)<br />
which gives the glass a soft colour and a<br />
marble-like texture.<br />
Since its introduction into the market<br />
in 1974, Neopariés has received<br />
enthusiastic acceptance from architects,<br />
as a material <strong>for</strong> the exterior and interior<br />
walls of modern buildings.<br />
Neopariés is said to combine the<br />
lustre of marble, with greater hardness,<br />
lower weight, higher resistance to<br />
weathering, zero water absorption, and<br />
ease of <strong>for</strong>mation into curved panels. RnF<br />

A VIEW FROM MOUTH FABER LOOKING NORTH<br />
THE Urban Redevelopment Authority (URA) of Singapore<br />
is all set to implement plans to link up the Southern Ridges<br />
and enhance it as an attractive recreational place <strong>for</strong> both<br />
Singaporeans and tourists.<br />
It recently announced the designs selected <strong>for</strong> the two<br />
bridges, one at Henderson Crossing and the other at<br />
Alexandra Link. URA will also begin planning the construction<br />
of a foot-trail which will take pedestrians from the<br />
Harbour Front MRT station right up to the cable car station<br />
at Mount Faber. From there, the visitor can use the soon-tobe-constructed<br />
bridges to explore the hill parks or take a<br />
ride to Sentosa via cable car.<br />
By 2007, when the bridges and foot trail are completed,<br />
visitors will be able to explore the entire stretch of green<br />
from Mount Faber Park to Alexandra Park. The bridges will<br />
link the Southern Ridges to the islandwide network of connected<br />
parks, allowing more people to enjoy Singapore’s<br />
natural areas easily.<br />
The two schemes were selected by a six-member selection<br />
panel, comprising representatives from URA, National<br />
Parks Board and Building and Construction Authority.<br />
The Surface Bridge at Henderson Crossing, was the<br />
submission of RSP Architects Planners & Engineers (Pte)<br />
Ltd in collaboration with IJP Corporation Ltd (UK).<br />
The Mile-a-Minute Bridge and Walkway was the concept<br />
put <strong>for</strong>ward by LOOK Architects and ECAS-EJ Consultants<br />
Pte Ltd.<br />
The selected teams will be appointed as Project Consultants<br />
<strong>for</strong> the respective bridges.<br />
The Surface Bridge will be about 274 m long, 8 m wide<br />
and 36 m high above the road carriageway. It will offer an<br />
interesting sculptural <strong>for</strong>m which would be appreciated<br />
when walking on the bridge deck or when viewed from the<br />
parks and the road. The bridge will be made up of five undulating<br />
curved ribs <strong>for</strong>ming alcoves that alternately rise<br />
over and under the bridge deck. The curved ribs <strong>for</strong>ming<br />
alcoves will function as shelters with seats within. The<br />
bridge will not be enclosed and the views of the surroundings<br />
change as one moves along the curved bridge.<br />
The Mile-a-Minute Bridge will be about 90 m long, 4 m<br />
wide and 5.4 m high above the Alexandra Road carriageway.<br />
The meandering walkway from the bridge to Telok<br />
Blangah Hill Park will be about 2.3 km long and 2 m wide.<br />
The scheme used the metaphor of the “tile-a-minute” plant<br />
to conceptualise the design of the bridge and walkway. The<br />
bridge will relate to the topography and vegetation of the<br />
site. It will be designed to cater <strong>for</strong> mass events, with an<br />
elevated walkway <strong>for</strong> pedestrians and a ground trail <strong>for</strong><br />
cyclists. RnF<br />

<strong>Roof</strong>&<strong>Facade</strong> Asia<br />
Laminated glass interlayers <strong>for</strong><br />
demanding applications<br />
ROOF & FACADE ASIA met<br />
with Dr Luc De Temmerman, Senior<br />
Vice President and Chief Operating<br />
Officer, Solutia Inc, manufacturers of<br />
laminated glass interlayers, during<br />
a recent trip he made to Singapore,<br />
and asked him about the company’s<br />
business prospects, product<br />
offerings and projects.<br />
R&F Asia: Briefly, what is the Dr Luc De Temmerman.<br />
strategy that Solutia has adopted<br />
<strong>for</strong> the medium-term, regarding business and product<br />
application, on a worldwide basis?<br />
Dr Luc De Temmerman: Solutia’s Laminated Glazing<br />
Interlayers business is focused globally on maintaining<br />
its role as the most reliable partner and the most<br />
innovative product and process provider in the<br />
marketplace. In short, this means both laminators and<br />
glass companies, as well as architects and designers, have<br />
complete confidence that Solutia’s interlayers are the best<br />
available in the world. In addition, they can rely on<br />
Solutia to provide the next generation of products with<br />
the benefits and enhancements they seek, to solve<br />
problems or raise the bar in design and execution.<br />
Globally, we started with safety and security products.<br />
We have in the recent past, added products with improved<br />
aesthetics including colour, acoustics, and solar and<br />
hurricane protection benefits to our range. The solar control<br />
products have been developed, particularly <strong>for</strong> customers<br />
in Asia. And more innovations are on the way.<br />
R&F Asia: From the point of view of the demand <strong>for</strong><br />
Solutia’s products, which are the important markets in<br />
Asia?<br />
Dr Luc De Temmerman: As regards the Asia Pacific region, our<br />
focus is on increasing the penetration of PVB in emerging<br />
markets like India, ASEAN, and China, and we offer products<br />
with additional benefits <strong>for</strong> the developed markets like Japan<br />
and Australia.<br />
The Asia Pacific markets remain very important to Solutia’s<br />
overall business strategy. It is our fastest growing region. We<br />
predict laminated glass demand in Asia Pacific will be growing<br />
6.5% to 7.5% annually over the next 4 to 5 years. Most of the<br />
growth will be in China. With respect to our growth, the Asia<br />
Pacific region has been growing close to 15% per year.<br />
R&F Asia: In this region, what specific products find<br />
application, and <strong>for</strong> what types of buildings?<br />
Dr Luc De Temmerman: Globally speaking, our<br />
architectural products are used in many different types<br />
of applications.<br />
Safety and Security are the drivers <strong>for</strong> both emerging<br />
markets such as China and India and <strong>for</strong> developed<br />
markets such as Australia and Japan, and this is mostly<br />
code driven.<br />
In the past, we had seen very high growth rates in<br />
China <strong>for</strong> use in bullet proof glass <strong>for</strong> banks. Aesthetics<br />
is an additional need and we are seeing steady growth in<br />
demand <strong>for</strong> the colour interlayers of our Vanceva range.<br />
Our high-per<strong>for</strong>mance Hurricane interlayers have<br />
been in great demand in the US, due to code requirements<br />
which will hopefully be implemented in other parts of<br />
the world, including the Asia Pacific region.<br />
We have seen increasing emphasis <strong>for</strong> Energy<br />
Conservation/ Green technology in the developed<br />
markets with solar being a driver and <strong>for</strong> which we have<br />
developed our Vanceva advanced solar control range of<br />
PVB products.<br />
Further, with the industry focus on protecting people<br />
and property, we have seen strong interest in our Saflex<br />
and Vanceva interlayers <strong>for</strong> security applications.<br />
Most of our Saflex and Vanceva interlayers go into<br />
facades in the commercial segment of the market – in<br />
high-rise office buildings, shopping centres, restaurants,<br />
showrooms, and in entertainment complexes, museums,<br />
airports etc.<br />
R&F Asia: Please explain how the company’s<br />
‘debottlenecking’ ef<strong>for</strong>ts help to meet the needs of customers<br />
in Asia.<br />
Dr Luc De Temmerman: As a result of a seamless,<br />
collaborative ef<strong>for</strong>t between Solutia’s technology and<br />
manufacturing teams, the Laminated Glazing Interlayers<br />
business is now benefiting from its ongoing<br />
debottlenecking ef<strong>for</strong>t at plant sites worldwide. More<br />
importantly, the results are helping Solutia to provide<br />
better service to its customers.<br />
For Asia, this means our laminator partners benefit<br />
from increased overall supply, supply confidence, and<br />
greater product and process innovation as they grow and<br />
expand their product offerings in the region.<br />
One example of our ef<strong>for</strong>ts in Asia is the increased<br />
emphasis we have put on our Singapore Finishing Centre,<br />
which ensures supply security in the region. The<br />
efficiency of the SFC is a main reason that Solutia<br />
continues to improve its impressive 95% On Time<br />
Delivery rate and earn strong customer satisfaction<br />
ratings in that category.<br />
R&F Asia: What are some of the recent, interesting<br />
projects where Solutia products have been used?<br />
Dr Luc De Temmerman: We have been involved in almost<br />
all the major airport projects that have come up in the<br />
region – Changi Terminal 1 and Terminal 2, Shanghai<br />
Pudong Airport, Guangzhou Airport, Chong Quing<br />
Airport, and the upcoming New Bangkok Airport Project,<br />
and we hope to be involved in the new ones coming up,<br />
such as Beijing Airport and Changi Terminal 3.<br />
We have been involved in sports infrastructure, like<br />
the World Cup Football stadium in France, facilities <strong>for</strong><br />
the Sydney Olympics, facilities <strong>for</strong> the Winter Olympics<br />
in Salt Lake City and the Flemington Race course in<br />
Australia. The Futian Sports Centre coming up in<br />
Shenzhen, China, will use Vanceva to achieve the five<br />
colours of the Olympic rings.<br />
We have seen increasing use of colour in the Asia<br />

Pacific region. For East Century Park in Taipei, Vanceva<br />
color in 10 different colours was used. Other projects<br />
using Vanceva color are Dalian Commercial Centre in<br />
China, Black Pearl in Taipei, Cyber Port Project in Hong<br />
Kong, and Changi Village Hotel in Singapore.<br />
Internationally, Media Market in Holland and Maestro<br />
Nicolau Street in Barcelona are some projects which use<br />
Vanceva color interlayers <strong>for</strong> facades.<br />
Our Vanceva interlayers with enhanced solar benefits<br />
were used in the recently inaugurated Guangzhou<br />
Airport project. We are doing a number of exciting<br />
projects with solar interlayers in Australia, like the Philips<br />
Street project.<br />
Our metallic interlayers from our Vanceva range have<br />
been used in facades in Okinawa by leading Japanese<br />
architect Shin Takamatsu.<br />
A good example of a facade application, is the Palmas<br />
building in Mexico that used Vanceva metallic and<br />
Vanceva color.<br />
R&F Asia: In summary, what distinguishes Solutia as a<br />
company?<br />
Dr Luc De Temmerman: We would claim several features.<br />
Firstly, we invest to produce quality products <strong>for</strong><br />
laminators. Secondly, in terms of customer service, we<br />
ensure on-time delivery of the products that architects,<br />
designers, facade consultants and other specifiers want,<br />
at the right price and with the highest quality. Thirdly,<br />
we employ the right people to provide technical service<br />
to customers. We also look <strong>for</strong>ward to working creatively<br />
with customers, to bring out new products. They<br />
determine what they need. We are there to develop these<br />
products and develop the market with them. RnF<br />
