2016 – Wallace was engaged by Hawkins Construction to undertake the concrete works to the Wellington International Airport southern extension to the Main Terminal Building. It was a new and significant project for Wellington Airport and the first major work to the Main Terminal Building since its opening in 1999.
Wallace designed and built the formwork for around 80 Insitu concrete columns ranging from 500-500mm up to 800x800mm. A mixture of Insitu and 16T precast beams were installed over 2 levels and stitched together with hollowcore and Flatdeck for the floor structure.
As the Airport has to be able to load and unload planes until around 11:00pm a lot of the major floor construction was completed at night over the baggage handlers roadway. Also noisy works such as scabbling and drilling had to be undertaken in the early hours of the morning to not disrupt the 15000 passengers travelling through the airport each day.
There was also upgrades done to the southern gates 9,10 and 11, A new pedestrian walkway down to the Sounds Air access with Hammerheads, ramps etc and works to the Existing façade on the runway side to allow installation of the Huge trusses that were installed over top of the existing terminal building.
