Retaining Walls

We have strong capabilities in the delivery of challenging civil and structural construction works, including piling, retaining walls, bulk earthworks, installation of service ducts, concrete reinstatement and construction of concrete foundations and footpaths. Our partnerships also enable us to provide other high quality service offerings for a diverse range of projects.

Southern Corridor Noise and Retaining Walls

Traction Room entered a Joint Venture with Gameon2 Contractors to construct 600m of concrete noise and retaining walls as part of the SH1 Southern Corridor improvement project, between Takanini and Papakura.

The walls consisted of steel columns embedded in reinforced concrete piles, with pre-cast concrete panels placed in between. We performed the work with twice the rate of production of the other contractor on site building noise walls at the time.

A section of the works was directly below 220kV overhead cables and required a complex installation methodology as panels could not always be slid from the top down, but needed to be installed from the side and held while each post was bolted in place.

We completed the work on time and defect free. Traction Room took ownership of the contract management, site management and all concrete and structural steel work.
