Scope

Retaining & Stabilisation

Environment

Remote Coastal

Project Overview

Moore Construction delivered retaining wall works at Okiwi Bay, providing a robust solution to stabilise ground conditions in a remote coastal environment.

The project required careful planning and execution due to restricted access, challenging terrain, and logistical constraints associated with working in an isolated location.

Engineering Solution

An H-pile retaining wall system was selected to provide a durable and efficient solution for stabilising the site while allowing flexibility during installation.

The system incorporated driven or bored steel H-piles with timber lagging, forming a retaining structure capable of adapting to ground variability and site conditions.

Construction Delivery

Installation works were undertaken using Moore Construction’s in-house plant and experienced team, ensuring precise placement and structural alignment of each pile.

Timber lagging was installed progressively between piles, providing immediate support to retained ground and allowing excavation and backfilling to proceed safely.

Project Challenges

The remote location introduced significant logistical challenges, including transport of plant, materials, and labour to site. Restricted working space and coastal conditions required adaptable construction methodologies.

Outcome

The completed retaining structure provides long-term stability for the site, demonstrating Moore Construction’s ability to deliver robust infrastructure in remote and challenging environments.
