2017 – Wallace completed the formwork and were the concrete subcontractor for Fletcher Construction at the 12000m2 Gateway Building at Victoria Universitys Kelburn campus. Wallace Building was engaged to undertake the enabling works to prepare for construction on two large sites. This involved Crane Bases for the 2 tower cranes and retaining works.
The Southern Zone was built literally into the side of a hill. Wallace constructed the suspended crane base early to allow construction of the 15m high anchored pile wall. 600mm dia piles were drilled into the ground to suit the existing topography and Wallace extended these piles up by forming 600mm columns up to 10m above the existing ground level. We also installed the 500m2 of timber lagging behind the columns to allow backfilling of Kelburn Parade
The Northern zone has been excavated approx. 6-9m deep into the existing carpark for construction of the large basement area which will eventually have the Culliford Drive over top of the basement roof. We installed the 200+ precast panels around the perimeter of the basement levels and the large shearwalls. Other work involved in the basement are the footings, panel stitches and insitu columns.
