Western Range Water Supply, Storage Tanks & NPI Surveying
Noble Surveys provided full engineering survey set-out and as-constructed documentation for the Western Range NPI Hub, supporting water supply infrastructure, storage tanks and enabling works. The project forms a key component of Rio Tinto’s Western Range mine development, expanding non-process infrastructure to support long-term operations. Our survey support ensured construction accuracy, seamless integration with existing assets and efficient delivery across all phases.
Project Challenges
- •Maintaining survey accuracy across multiple active work fronts operating simultaneously within a busy mining environment.
- •Integrating new water supply, pipeline and storage infrastructure with existing operational assets and legacy survey control.
- •Supporting tight construction sequencing and providing rapid survey turnarounds to keep overlapping contractors on schedule.
- •Managing survey access, logistics and coverage across remote Pilbara terrain and variable site conditions.
- •Ensuring consistent QA, conformance reporting and as-constructed documentation across numerous crews and shifting priorities.
- •Coordinating survey data through design updates, construction changes and evolving project scope across the NPI hub.
Our Solutions
- •Established a unified, high-accuracy survey control network to support all work fronts and maintain consistency across the NPI precinct.
- •Delivered rapid set-out, conformance checks and as-constructed capture to keep contractors aligned with design requirements and construction sequencing.
- •Implemented efficient communication and coordination processes to support multiple teams, disciplines and shifting priorities.
- •Utilised modern survey technology including GNSS, total stations and digital terrain modelling to improve accuracy and reduce rework.
- •Integrated survey data into updated design models to manage revisions and ensure seamless alignment with existing infrastructure.
- •Provided structured QA workflows and clear documentation to support compliance, handover and long-term asset management.
Project Outcomes
- •Achieved consistent, high-accuracy set-out and as-constructed documentation across all work fronts, supporting reliable construction delivery.
- •Reduced rework and construction delays through clear survey control, rapid turnaround of set-out requests and proactive issue identification.
- •Improved coordination between contractors, engineers and site supervisors through structured communication and integrated survey workflows.
- •Ensured seamless integration of new water supply, storage and NPI infrastructure with existing operational assets.
- •Delivered complete, QA-verified as-constructed records to support project handover, commissioning and long-term asset management.
- •Enhanced safety and operational efficiency by providing precise spatial data to inform construction planning and onsite decision-making.
