Fletcher Construction on behalf of Precinct Properties
A Class Asbestos Removal Works
Commercial Bay has been established in the heart of Aucklands downtown. The initial stages of the project consisted of the demolition of the 3-5 floor Westfield mall to make way for a new shopping district, with the new PWC tower as its centre piece.
As part of these works the City Rail Link was extended from Britomart, straight through the basement of the commercial bay site.
ATL were engaged for the asbestos removal for the entire project, which was spread over two major stages, the first being the asbestos removal throughout the mall while the demolition was taking place, and the second was the removal of rope embedded in the external brickwork on the lower three floors of HSBC and ZURICH house. 98% of the works were completed under full friable conditions.
This project was completed in conjunction with the Demolition subcontractor and main contractor despite mate environmental and site challenges.
Scope of Work
Initial scope was drawn from surveys completed on the three structures. ATL were engaged for the entire asbestos works, which included:
Fiber cement Friable and non friable vinyl Asbestos containing membrane on external horizontal surfaces Gasket removal Duct putty removal Asbestos rope throughout the entire south building of the Westfield mall
On a project of this size and complexity, meeting deadlines is the most common challenge. This was no different in that respect, but we also had the added trials of finding asbestos in very strange places which were new to the scope. One such place was late in the demolition phase, where rope was used as a packer around a boiler flu. This in itself if fine, however the flu spanned from the basement, through the roof of level 4, and the rope was wound around in one continuous piece.
Another interesting addition to the scope which was uncovered during the soft strip was the discovery of rope running between every pillar, attached to the concrete subfloor. This meant we had to deal with around 10800m2 of floor space as full friable, while being held to the very tight demolition deadlines.
