Project Overview

Location: Westshore, Napier

Build type: Multi-unit residential (6 villas)

Developer: Oniram Investments Ltd

Lead Builder: TW Construction

A stepped residential development comprising six villas, designed with shared access and integrated lift infrastructure across the site.

Site Challenges

• Ground conditions included non-engineered fill and shallow groundwater, requiring ground improvement

• Need for consistency across multiple adjoining units

• Integration of lift pits into the slab without disrupting structural performance

• Repetition of units requiring a systemised, predictable approach

Technical Detail Overview

The QPOD system was designed as QPOD’s Raft Configuration to work in conjunction with a ground improvement build-up, including:

• excavation to approximately 0.6 m below ground level

• geofabric lining

• geogrid reinforcement

• compacted AP65 gravel or equivalent to achieve the required density.

The foundation plan also incorporated:

• 300 mm wide perimeter foundations

• multiple 250 mm step-downs

• integrated lift pit

Outcome

This project shows what the QPOD system does well at scale.

The result was a tidy, repeatable installation with integrated lift infrastructure, predictable slab geometry, and a foundation platform suited to the realities of Westshore ground conditions.
