We're thrilled that our Westland Milk Outfall Package 2 project was recognised at the recent CCNZ Hirepool Construction Excellence Awards held in Christchurch, New Zealand. The project received a high commendation in the projects over $5 million category.
As one of New Zealand’s most technically challenging projects comprising both marine and tunnelling, Westland Milk’s Outfall was a project dear to our heart. Located on the ‘wild’ west coast of the South Island, and subject to the region’s extreme and unpredictable coastal weather, we pulled out all stops to de-risk construction and increase certainty through a method that combined unique-in-NZ direct pipe (trenchless) expertise, and meticulous planning, practice and preparation.
Going trenchless was a key factor in minimising construction environmental impacts, enabling us to reduce the size and number of shafts required to install the pipe. Drawing on accumulated experience from McConnell Dowell’s delivery of all bar one of NZ’s outfalls, was also a key success factor – supporting us to make the tweaks in planning and process that resulted in completion of the 844 m tunnel drive ahead of programme!
