Overview:

Urgent increased capacity was required in prisons across New Zealand. Isaac Construction completed works on Rolleston, Christchurch Women's and Men's Prisons in three phases.To deliver this project under extreme control and high security, Isaac ensured collaboration and clear communication remained our highest priority, as external interfacing works with building works were critical to ensuring on-time programme delivery. The scope of works included both perimeter and internal roads, and infrastructure with all works on all three prisons completed on time, to budget and to a very high standard, which our large Isaac team constantly strives.

Rolleston Prison

The goal of this project was to widen the prison's footprint to accommodate new buildings, and the scope of construction for all external civil works included site clearance, setting out, earthworks and construction of a new 2km perimeter security fence, with a 3m perimeter road either side of the fence, construction of site access, vehicle checkpoint, and staff and visitor car park facilities, telecommunication and security trenches, ducts and access chambers, and the installation of services for the new ancillary buildings to facilitate the development as part of PCP1D.Given the location and nature of this contract, it was delivered under extreme control and high security. Clear communication was paramount, as external interfacing works with building works were critical to ensuring on-time programme delivery.

Christchurch Woman’s Prison

In February 2019, Isaac established earthworks teams into the Christchurch Women’s Prison. The scope of works was very similar, except for the addition of two large car park extensions, which meant Kevin, Tony and the teams could continue to improve on their innovative and collaborative construction methodologies; by bringing in a couple of employees from our paving division, the team were able to achieve an average of 3000m2 of basecourse constructed per day using a machine controlled asphalt paver instead of a grade.

Christchurch Men’s Prison

The works a Christchurch Men’s Prison were tendered and won in March 2019 and works commenced in April. This project differed from the previous two, as the access road and ducting were inside the prison’s footprint. However, it also included a significant car park upgrade.
