Our client, Classic Developments Limited, planned a terraced development for this site. This required a significant retaining wall, 4.5m high and 150m long, running along 13 separate boundaries. The viability of the entire subdivision depended on getting the design of this retaining structure exactly right, which kept the project team on their toes throughout.
Vitruvius was engaged to undertake the topographical survey and civil engineering design for the project. We worked closely with the geotechnical engineer to determine the correct offsets and boundaries, pinpointing precisely where the wall needed to be located. Poles were driven up to 12m deep into the ground, resulting in a highly stable site, with resource consent and development works approval subsequently granted by Tauranga City Council.
Providing drainage services through the wall was the next key challenge. Large manholes and drop structures were designed to allow stormwater and wastewater pipes to pass through from one side to the other.
Managing complex engineering challenges like this is what we do best. The completed project delivered a strong, well‑engineered solution that also integrates seamlessly into the surrounding landscape.
