The National Park Service awarded a $226.4 million definitive contract to Stronghold Engineering Inc., a minority-owned, woman-owned, and Asian-Pacific American-owned small business, for replacement and improvement of potable water systems at Grand Canyon National Park on March 14, 2023, with an ultimate completion date of January 8, 2028.
The originating pre-solicitation, posted February 24, 2022, sought comprehensive rehabilitation of Grand Canyon's primary water supply system, including new surface water intake and treatment facilities, replacement of distribution piping via open cut and slipline methods, installation of new storage tanks, and point-of-use disinfection systems serving inner canyon and south rim areas. The project addresses water delivery to remote areas requiring helicopter coordination for inner canyon operations. Work is firm fixed price with place of performance in Grand Canyon Village, Arizona.
Through fiscal 2025, Stronghold Engineering has invoiced $182.6 million across the contract's active years. FY2025 labor footprint stands at 95.1 FTEs performing 197,717 contractor hours; the derived government-paid blended rate (prime and subcontractor) was $371.46 per hour. The contractor engages 16 subcontractors, with approximately 47 percent of hours subcontracted. The blended hourly rate has declined year-over-year from $825.51 in FY2023 to $371.46 in FY2025, reflecting shift in work phase composition and subcontractor deployment as the project advances.
