CLIENT: ANZ
BUILDER: Bovis Lend Lease
PURPOSE AND SIZE: Commercial: 83,550 m²
COMPLETION DATE: end 2009
PROJECT DURATION: 12 Months
ACCESS FLOOR SYSTEM USED: Steel Cementitious 4.5kN Heavy Grade Load on an Ultrafix Stringerless Air Tight Understructure. System Code: SC-64-4.5-UF-AT
PROJECT SCOPE/SPECIFICATION: The ANZ project required an Air Tight access floor system with smoke and zone baffling. Due to the design of the mechanical units, the specification required each zone to be tested to comply with a controlled air leakage rate of 0.7277 l/s.m2 prior to the installation of floor coverings.
The project also required an Air Tight System that could be easily integrated with other services.
PROJECT FEATURES AND HIGHLIGHTS: –
A controlled air leakage rate was achieved. Each zone was tested and complied with an air leakage rate of:
a) 0.7277 l/s.m2 without floor coverings
b) 0.1386 l/s.m2 with floor coverings
The large floor plate, of up to and over 10,000m2, would have proved to be a challenge in terms of expansion and creep if it was not for our specially designed and patented pedestal head and panel. The panel has a special expansion cut out, and the pedestal head is fitted with an expansion gasket designed to keep the panels separated by 0.3mm at all times. This eliminates the panels clicking or rubbing up against each other during expansion.
The use of bridging stringers for services ensured penetrations in the ductwork were kept to a minimum. ASP staff coordinated with other services to ensure penetrations were correctly located and properly sealed.
