| Over
50,000m² of straight, curved and tapered convex curved
Kalzip aluminium standing seam sheets have been installed on
Dublin Airport’s impressive new Terminal 2 building, Pier E
and associated buildings. Arup and lead architects
Pascall+Watson specified a full acoustic Kalzip system for
T2 which was installed by Portuguese building envelope
project manager and contractor, Martifer. |

Kalzip’s technical team worked
very closely with Martifer and the project’s many demands
have put the two company’s capabilities to the test. A
combination of successful teamwork, thorough training, sheer
hard work and determination proved vital in providing a
number of creative solutions to various construction
challenges and in meeting the client’s needs. |
|
Martifer’s Hugo Camacho says,
“Although we looked at a number of building system
suppliers, Kalzip convinced us through a series of meetings
and presentations that they would deliver the best solution
for the building envelope. Kalzip simultaneously
demonstrated that they possess the necessary technical
design and commercial expertise to identify and overcome the
many structural, acoustic and thermal requirements posed by
this challenging building project.” |
|
One particularly difficult task
faced by the team was getting the decking to work
successfully in conjunction with the high load span
conditions. This was further complicated by the general span
of the steelwork which in some places exceeds 9 metres. The
intricate geometry of the steelwork and the extra loading of
the rainscreen system also had to be accommodated by the
Kalzip and the structural decking systems. |
|
Most of the 1.2mm thick Kalzip
sheets were roll formed onsite because it was more economic
and environmentally friendly. T2’s acoustic requirements
have been achieved using a shallow profiled fully perforated
Kalzip liner panel system complete with 50mm thick 60kg
density insulation to provide a ceiling that has been
installed by Martifer from below. |
|
The T2 building has two main
sections which sit astride the existing access road to
Terminal 1 - a Check-in area and a Departures / Arrivals
area that are connected via a link bridge. A rainscreen
system has been installed on the Kalzip sheets covering this
Check-in area and the tightly curved parts of the Arrival /
Departures area. Kalzip developed a special seam clip
enabling Martifer to achieve a suitably robust connection
between the Kalzip weather sheets and their rainscreen
support system. |
|
A central spine continues from
the main 3-storey curvilinear T2 building through to the 400
metre long Pier E that will provide boarding gates and
parking for up to 19 aircraft. PJ Hegarty & Sons are the
main contractor and Lynch Roofing Systems Ltd the Teamkal
contractor for Pier E. |
|
Due to be operational towards
the end of 2010, the new T2 development has been designed
and managed by a senior project team comprising Arup,
Pascall+Watson and Mace to meet the needs of both long-haul
and short-haul passengers and airlines. When fully
operational, T2 will be capable of comfortably handling up
to 15 million passengers per year. |
