Jade Lake Development- Queenstown

Slope Stabilisation & Anchored Retaining System — Queenstown

Location

Queenstown

Excavation

12.5m

Anchors

64

System

Anchored Shotcrete

Project Overview

Moore Construction delivered complex slope stabilisation works for the Jade Lake Development, supporting excavation adjacent to an existing residential structure within a constrained site environment.

Excavation to depths of 12.5 metres was undertaken in controlled stages to maintain ground stability and protect surrounding assets.

Engineering Solution

A staged anchored retaining system combining permanent ground anchors and reinforced shotcrete was implemented to ensure long-term stability and performance.

Construction Methodology

  • 64 permanent ground anchors installed
  • Anchor depths 5m – 12m
  • Installed in 4 rows at 3m spacing
  • 150mm shotcrete applied progressively

Excavation was performed in staged lifts, with each level stabilised before proceeding, ensuring continuous control of ground conditions.

Construction Delivery

All works were completed by Moore Construction’s in-house team, including fabrication of specialised tooling to improve efficiency and precision.
