Company: Firth Industries
The ASB Building on the North Wharf on Auckland’s ‘Tank Farm’ is the new home to 1100 ASB Bank staff and is the talk of the town.
“We have been involved in this building with the architects from the start which included significant technical input to create the black polished floor with Jason Torbet and his team from Polished Concrete Ltd who produced a magnificent finish,” says Bernice Cumming, Architectural Manager for Firth. “We were really pleased to see that Jason and his team won Best Commercial Floor at the recent Concrete Services Polished Concrete Awards knowing the work that went into getting the mixes and colour constancy right.”
When construction first began the designers wanted the concrete to have a high-grade, smooth finish for everything from the columns to the beams. Firth was able to work with the customer to develop a mix that proved to be exactly what the designers required.
When it came to the finishing touches to the building Fletchers (the building contractors) were after a polished floor, finished to a high spec, to highlight the wonderful features the building has on offer. A number of meetings were held over the design of the concrete and the methodology for the placement and polishing of the floor. “It wasn’t just about getting the concrete right,” says Rob McKinnon, Materials Manager – Northern for Firth. “It was about getting all the elements from all the parties right.”
Testing and trial mixes were carried out and test slabs put down. “The stockpiles of materials were ‘ring-fenced’ so as to ensure uniformity of product over the number of pours that would be required,” adds Rob.
The result is a spectacular floor that showcases the wonderful design elements of this building and is a credit to all that were involved in its construction.
