Overview
The project involved the construction of a service corridor with the installation and commissioning of 13 primary lines, each 1km in length. Services included Tails, Seepage, Potable Water, Sewer, Saline, and Decant lines. The site was adjacent to a live mine processing facility and mining workshops.
The works included large-scale earthworks cut and fill, installation of culverts, pouring in situ concrete road crossings, staging of cutovers and removal of pre-existing services corridor. Doolee undertook the civil aspects of the project working closely with NSR and other mine stakeholders to ensure smooth completion and minimum disruption to operations and processing within the mine. The project started in March 2024 with completion in August 2024.
Scope of work
- Bulk earthworks cut and fill
- Construction of temporary and permanent ring roads
- Installation of temporary and permanent valve stations
- Placement of 240 culverts and lids
- In situ concrete works such as road crossings, retaining walls, thrust blocks and pedestals
- Removal of existing services corridor piping
Our team delivered comprehensive piping solutions, utilising professional poly pipe welding to ensure long-term durability for the site’s water infrastructure.
Our team provided specialised HDPE welding and piping installation as a core component of the NSR Stage 2 enabling works.
Challenges
