The managing contractor for the project is a joint venture between John Holland (a national company) and Fairbrother (a Tasmanian company). They will build the facilities in conjunction with many subcontractors - mostly Tasmanian businesses.
Prison buildings will generally be made of a mix of reinforced concrete, pre-cast concrete panels and reinforced concrete block work, with Zincalume roofs.
The Wilfred Lopes Centre (SMHU) will be constructed of concrete block and brick walls on a concrete slab, with some internal studwork walls.
The existing part of the women's prison will retain the green roof. The rest of the roofs will be Zincalume.
The new buildings will be pre-cast concrete so the colour will be natural grey.
The secure mental health unit will have colour in the brickwork and a Colorbond fence.
The total cost of the new prisons and secure mental health unit is $89 million. This includes all of the project costs - planning, design and construction.
