Case studies – ASB Sports Centre, Wellington
72 Kemp Street
The ASB Sports Centre features a Junckers Beech Unobat62 system timber sports floor imported from Denmark. The boards came pre-finished and the floor installation took fourteen weeks, using a team of up to seventeen men. Once installed the floor was line-marked for the different disciplines. Finally, a coat of polyurethane was applied to protect the line markings and provide a uniform finish.
One of the challenges of the project was to have the concrete slab ready for the sports floor. The timber sports floor could accommodate very little tolerance. However, it was laid on a large concrete slab with all the vagaries that go with concrete as a medium. Aardvark Concrete Services was tasked with laying this important foundation.
The building is naturally ventilated which is uncommon for such a large sports centre. In between the concrete panels that march around the exterior are full height glass louvres which are computer controlled. Two weather stations mounted around the site and multiple sensors within the building feed information back to the computer so it can determine which louvres should be open. There are also louvres in the roof trough to allow heat that rises to escape without the aid of fans.
Natural light also plays a big role. There are skylights over each of the trusses and sensors control the fluorescent lighting to only come on gradually when the natural illumination is not sufficient on its own.
The construction of the ASB Sports Centre included two noteworthy New Zealand firsts; it is the first project to use steel elliptical tapered columns and the first to use a Kalzip roof.
The Wellington ASB Sports Centre is an impressive engineering and architectural feat and the Aardvark team is proud to have played a part in its creation.
