Harrison Grierson was awarded ‘’Best Team Award’’ at the Auckland Property People Awards (run by The Property Company) for our work on the Auckland Zoo’s Southeast Asia Precinct Jungle Track. We partnered with Beca, NZ Strong, Jacobs, Ignite Architects, Studio Hanson Roberts and Stevens Lawson to work on the biggest and most ambitious project in the zoo’s 100-year history. Over six years, the precinct was transformed to emulate the natural environment of the animals, while preserving the integrity of the facility.

We were part of the team who won gold at the Auckland CCNZ HYNDS Construction Awards for work on the Mairangi Bay Pump Station. Our partners Pipeline & Civil Ltd helped us to create a pump station for the residents of Long Bay, Castor Bay, and Mairangi Bay in Tāmaki Makaurau to give them better drainage and was recognised by award judges for its sustainable design which reduced the need for too much excavation. The small site sure did bring about its challenges - and throw into the mix Covid - but the team came out on top and showcased their design skills and resilience. A great three-year project!
