Wainui Rd / Silverdale St Roundabout​

Wainui Road / SIverdale Street Roundabout​

We were contracted to build the roundabout and approaches; kerb and channel a 500mm granular pavement built to Transit B2 specification; construct a new 2.5m cycleway and complete drainage, subsoil drains, new utility services and minor earthworks

All Sediment and Erosion Control was completed to ARC TP90 requirements.

Project role: We were the main contractor and undertook all works with our own staff except pavement sealing which was subcontracted to Works Infrastructure.


Track Record: This was a high profile contract due to the proximity of new schools and the requirement to maintain the 5000 vehicles per day traffic flows at all times as the roundabout linked the exit roads to the Whangaparaoa intersection. The works included managing traffic from four directions and the Opie team were consistent in ensuring the traffic was able to keep moving at all times.

This work was completed after the Silverdale Parkway four-lane project was finished under a separate contract that was also completed successfully by our company.  We were also requested by Council to continue with an extension of the project which was completed successfully by our Company.
