Welles Street - Atlas Quarter
The right foundations for a vibrant new community in Christchurch
With a vision to bring people back into central Christchurch following the 2010 and 2011 earthquakes, Fletcher Living agreed to a partnership with MBIE (Ministry for Building Innovation and Employment in New Zealand) to redevelop the old Atlas Foundry in Welles Street, close to Christchurch CBD, into a medium-density residential development.
Designed to be a vibrant new community, the redevelopment includes 191 new homes, a mix of apartments and terraced housing.
Early involvement was crucial to developing a cost-effective solution.
Challenging ground conditions necessitated a well-considered foundation solution, so Fletcher Living engaged Piletech and Brian Perry Civil during the tender phase to identify the right approach. This early involvement was crucial to developing a cost-effective solution. Piletech’s long-standing relationships in Christchurch also played a key role in the selection of the structural consultant to design the project, Aurecon.
Piletech undertook a range of multiple load tests for compression and tension, before recommending the final solution. The load tests not only provided surety of our design, but also vastly reduce the overall piling costs.
The solution chosen was installation of over 330 screw piles - split between 3 buildings, to depths of up to 29 metres. In total 4.2 km of pipe was installed. This pipe was filled with 190m3 of concrete and 2,514 metres of reinforcing was installed.
