Lavarack Barracks Intersections

Detailed Design for key intersections

Project Owner

Department of Defence

Location

Townsville

Completed

2025

Detailed civil engineering design for two upgraded intersections within Lavarack Barracks, improving heavy vehicle access, road geometry and operational functionality as part of the Defence Capital Works program.

Project Overview

Civil IQ was engaged to prepare the detailed design for two intersections at key road network locations as part of the Lavarack Barracks Capitals Works program.

The existing intersections required road widening to allow for turning paths of the large HX81 Defence vehicles.

The project was a Design and Construct contract with Shamrock Civil Engineering.

Challenges

  • $
    Limited timeframes to have design and construction completed prior to the 2024/2025 wet season
  • $
    Road geometry was significantly constrained by existing infrastructure including culvert crossing, services, footpaths and terrain
  • $
    Culvert extension of 6x1800x1800 Reinforced Concrete Box Culverts
  • $
    Ongoing coordination and collaboration with Shamrock Civil Engineering during construction to ensure design intent is met in construction

Outcomes

  • $
    HX81 Defence vehicles are able to manouevre through the two intersections and surrounding roadways
  • $
    Successful completion of all construction works prior to the wet season and RPEQ certification

Scope

  • $
    Geotechnical investigations and assessments
  • $
    Detailed design
