Engineering and strategic support for Spence Mine’s 20-year water supply contract
We partnered with BHP to provide strategic and technical expertise for the Spence Growth Options Project in Chile. This effort depends on a desalinated water supply delivered under a 20-year BOOT (Build–Own–Operate–Transfer) contract. For eight years, we supported BHP from identifying and evaluating joint ventures for the BOOT award through project execution, and now into the operational phase.
Procurement support
We helped BHP choose the best partners, view bids, and shape the contract for this major water project. Our team guided evaluations, answered questions and supported negotiations.
Execution support
Our team reviewed technical submittals to ensure quality and provided hands-on support during construction and commissioning to help the project launch successfully.
Operation support
During the operational phase, we reviewed operation and maintenance documents to ensure smooth performance.
The Spence Growth Options Project is a critical initiative to secure water for mining operations in Chile’s Atacama Desert, one of the driest regions in the world. We supported BHP in developing a sustainable solution that includes a 23-million-gallon-per-day seawater osmosis plant, marine works, a 95-mile pipeline to deliver desalinated water and a dedicated power system. Under a 20-year BOOT contract, our team provided strategic guidance from partner selection and procurement through construction and commissioning. Today, we continue to assist operations, overseeing reliable water delivery and long-term mining sustainability.
