CSC was contracted for the Albion Riverside project in Battersea to deploy operatives day and night to install 10,000 square meters of traditional fiber screed and bring the programme back on track after being contracted at a late stage.
The City of Toronto is in the final stages of detailed design for the new pedestrian / cycling bridge to be constructed over the Metrolinx Union Station Rail Corridor, from Douro Street to the western leg of Western Battery Road.

The document provides details about the construction of the O2 Arena in London, England. It was originally built to house the Millennium Experience exhibition under a large dome structure. The dome has a diameter of 320 meters and is constructed out of a PTFE-coated glass fiber fabric membrane supported by 72 tensioned steel stringer cables. Reinforced concrete was used at 24 anchor points around the dome to support the cable structure. The dome provides an open interior space under a lightweight tensile structure.

The document summarizes an industrial project in Sasolburg, South Africa to construct a building replicating a European design to house Sasol's process of making liquid fuel from gas. The project team included Sasol as developer and owner, with Walker Smith Architects, BKS, and Royal Haskoning as architect, structural engineer, and quantity surveyor. The main contractor was Haskoning International with Imbabala/Van Staden Engineering as steelwork contractor. The structure was built according to South African standards interpreting the original European design, going up in under three months using 555 tons of steel. Exacting quality, safety, and corrosion protection requirements were challenges in constructing this example of an industrial project.
The London Eye is a giant Ferris wheel situated on the banks of the River Thames in London. It is 443 feet tall and its wheel has a diameter of 394 feet, making it the tallest Ferris wheel in Europe. Over 3.5 million people visit the London Eye annually. It provides views of London from 135 meters high and each capsule can hold up to 25 people. The London Eye opened in 2000 and has since become a major tourist attraction in London.
The Kelpies are two large equine sculptures made of stainless steel that stand as a landmark in Scotland. Constructed by artist Andy Scott and engineers, each head used 150 tons of stainless steel and mild steel. They were a challenging project to design and fabricate due to their enormous size, with complex engineering and fabrication methods required. The Kelpies pay homage to Scotland's industrial history and were designed to withstand weathering for generations to come.
1. J
ames Miller certainly left his mark on Scotland. As an architect for the Caledonian Railway he
designed a number of Scottish stations, including those on the West Highland line. After setting
up his own practice in 1893, he designed various notable buildings in Glasgow including the
Royal Infirmary. Further afield, he devised the palatial interiors of the liner Lusitania, which was
sunk by a German submarine, and, in 1910, won the competition for the design of the London
headquarters of the Institution of Civil Engineers.
His output was prodigious and included
commissions for station designs from his
old employer, the Caledonian Railway. These
included the elaborate glazed curved canopies
of Wemyss Bay station and its walkway to the
pier, when the station was rebuilt in 1903 to
accommodate increasing numbers of paddle
steamer passengers. He also designed the 1906
extension to Glasgow Central and its hotel.
Miller’s extravaganza
It is therefore not surprising that Miller was
chosen to design the new station at Stirling that
opened in 1915. While there had been a station
at Stirling since 1848, as more lines opened,
operated by different companies, the station
proved inadequate. In 1889, the Caledonian
Railway and North British Railway agreed to
enlarge the station and sought powers for
additional land. Yet work on the new station,
which is essentially the current station, did not
start until 1914.
The new station was described as a “crow-
stepped gabled and crenelated façade to the
street that hides a low, spacious and beautiful
concourse, a miniature repeat of Miller’s
extravaganza at Wemyss Bay” when it opened
on New Year’s day in 1915.
In recent times, the station had
a profusion of flowers and
was judged to be the
best-presented station in Scotland in 1993.
This tradition has now been reinstated by
the Rotary Club of Scotland which recently
adopted the station as part of ScotRail’s
‘adopt a station’ scheme to encourage
community involvement. Since then, the
Rotary’s plants have brightened up the
station, although this was not helped by the
dirty glass above.
Polycarbonate replaces glass
A hundred years ago the only material
available to Miller to create his ‘extravaganza’
was glass. Today, six millimetre thick sheets
of Makrolon® lightweight, self-cleaning
polycarbonate provide a superior glazing
material which, when used with the Twinfix
Multi-Link Panel NF glazing system, is a non-
fragile panel that can be quickly installed. The
need for this was clear as an estimated one in
six of the glass roof panels had been cracked
as a result of vibration from freight trains and
there were concerns that a damaged panel
might fall onto one of the platforms below.

2. Although the Makrolon sheets used were a
Georgian-wired cast-effect polycarbonate which
is virtually unbreakable, Stirling City Council’s
planners were not convinced. Hence it took
two years for Network Rail to obtain planning
permission to re-glaze the Category A-listed
Stirling station.
One concern was that polycarbonate would
discolour over time and so would undermine
the “architectural integrity” of the station. This
was addressed by tests that demonstrated
polycarbonate would not discolour in the
short term and an agreement for ten-yearly
inspections, following which any discoloured
panes would be replaced.
The planners were also not prepared to accept
the use of Twinfix standard 70mm glazing bars
as the existing station bars were 50mm wide. To
address this issue, Twinfix designed a new glazing
bar and produced a ‘mock up’ using a 3D printer.
This was shown to the planners, to convince them
that this was acceptable, and was also used to
confirm the dimensional tolerances of a glazing
system incorporating the new 50mm bar.
Once planning permission had been received,
Story Contracting was able to start the roof works
last August. These included,
in addition to re-
glazing the 2,440 square metre roof, inspection,
repairs and painting of the supporting structure
as well as relining cast iron gutters and cleaning
downpipes, all at a total cost of £2.5 million. The
design and execution of this work was part of the
station framework contract which Network Rail
Scotland had awarded to
Story in 2014.
Story’s designer was Arup, which was primarily
concerned with the connection between the
steelwork and the glazing system. As the
polycarbonate sheets are much lighter than
glass, particular consideration had to be given to
wind uplift.
The glazing system, designed by Twinfix, was
quick to install as each panel interlocks to the
adjacent one.

3. Roof access
A recent innovation is the roof access hatches
(pirctured above). These form an integral part of
the glazing system and had been developed by
Twinfix in response to a request from Network Rail
that maintenance could be undertaken without the
need to gain access above the glazing. At Stirling,
174 such hatches were installed at 4.2 metre
centres from which gutter cleaning and other work
can be carried out using six-foot-long omnipoles.
Story’s rail director for Scotland, John
MacArthur, considers that Stirling’s historic
station is not only a high profile project, but also
one that presented some interesting challenges.
It had originally been thought that the cast iron
glazing in the round concourse area would be
one of them. However, once the panel sizes
were determined, it was found that they were
all the same size as the circular glazing was
geometrically perfect.
In contrast, there is a significant degree of
non-uniformity of the supporting steelwork over
the slightly curved platforms. This may have
been deformed due to wind loading over the
past hundred years but, whatever the reason,
the result was that a significant number of
glazing panels were of a non-standard size.
Hence Twinfix had a small installation team on
site which cut individual panels to the required
dimensions. John estimated that this was
necessary for 10 per cent of the panels.
The original steelwork was generally in good
condition and only required occasional localised
repairs before painting. John felt it had been
well maintained, perhaps as a result of Stirling
being a relatively small and high-profile station.
The paint used was a three-coat M24 epoxy
protective system applied over the existing lead
paint which had previously been prepared using
power tools.
The roofing work was undertaken from a fully
enclosed crash deck above the platforms. This
was erected during a night station closure using
rules of route possessions for work close to the
platform edge. In this way, the 46,000 passengers
who use the station each week were not affected
and there were no platform closures.
Maintaining sightlines
Stirling’s slightly curved platforms did,
however, present another problem as the crash
deck scaffolding hoardings could potentially
affect train despatch sightlines. In consultation
with ScotRail, this problem was resolved by
closing off the area underneath the crash deck
with heavy duty netting through which sight
lines could be maintained. It was therefore
possible to erect a larger area of crash deck than
would otherwise have been possible, greatly
improving productivity.
In this way, most of the work took place
both during the dayshift and in a high street
environment. However, possessions were
required for the re-lining of the gutters using
mobile elevating work platforms to work over
the dagger boards.
Story completed its Stirling station roof work
in June, two months ahead of schedule. John
MacArthur considers that the key reason for
this early finish was the use of a larger crash
deck than was originally planned, the result of
good collaboration between Story, Twinfix and
ScotRail’s station management team.
Above the city is Stirling’s castle and its
medieval town - one of Scotland’s great tourist
attractions. While it offers much for those with
an interest in architecture, they should also
venture below the castle to see the architectural
gem that is James Miller’s Stirling station. With
its new roof, and flowers from the Rotary, it is
certainly a sight worth seeing.

Twinfix is a family run business.
As experienced innovators they offer
a range of well-engineered glazing
products, many of which are fitted on
the roofs of Rail Stations and Depots.
The Multi-Link-Panel installed by Story Contracting
at Stirling Station in Scotland is an aluminium-framed,
modular rooflight system, designed with a unique fixing
method that results in incredibly quick installation times.
In order to drive efficiencies within their work in rail
Twinfix have utilised up-to-date 3D printing to aid
product innovation and development, employing this
new technology to view a 3D model of a revised
Multi-Link bar design for use in future rail applications.
For ease of specification the Multi-Link-Panel is available
as a BIM object for download in IFC and Revit formats
from the Twinfix website.
The Twinfix collaboration with Story Contracting on
Stirling Station is a great example of Twinfix Georgian
wired effect polycarbonate in their Multi-Link Non-Fragile
panel. The polycarbonate glazing looks the same as the
traditional Georgian wired glass but will not break.
The benefits of this system are:
• Safe in use: All Multi-Link-Panels pass the
ACR[M]001:2014 drop test, in accordance with
HSE recommendations, with a ‘B’ designation.
• The Twinfix Georgian wired grade solid
polycarbonate is particularly popular as it mimics
Georgian wired glass.
• Polycarbonate absorbs vibrations without
cracking, crazing or breaking.
• The aluminium framework can be powder coated
to a RAL colour to suit your project.
• The light weight of the finished product results
in less stress to the fabric of original buildings.
• Sleek in-line access hatches (developed at
the request of Network Rail) offer unobtrusive
and safe access through the glazing for
maintenance purposes.
• Factory manufactured rooflight panels means
no costly mistakes on site.
