Granite Construction has more water business flowing its way.
The Watsonville, California-based contractor has won a construction-manager-at-risk contract, along with joint venture partner Contri Construction of Las Vegas, from the Southern Nevada Water Authority, according to a June 23 news release. Granite’s total estimated construction contract value is $240 million, the firm said.
Granite and Contri formed Southern Nevada Construction Partners to deliver the preconstruction phase of the Paradise Hills portion of SNWA’s larger, $2.7 billion Horizontal Lateral Program, which is aimed at protecting and improving water delivery and reliability in the Las Vegas Valley.
SNCP’s contract scope includes the installation of approximately 22,000 linear feet of 120-inch steel water pipeline, which will encompass three trenchless crossings beneath an existing 108-inch waterline, Interstate 11 and Union Pacific Railroad tracks. Contri will be responsible for installing the 120-inch pipeline and associated equipment, according to the release.
Construction will also incorporate multiple valved outlets for future connections to Boulder City, the city of Henderson’s Reservoir R-8 and the Horizon Lateral pipeline. Also under scope is the construction of a pumping station with a 65 million-gallons-per-day capacity, which will initially operate at 35 million gallons per day, per the release.
The facility will comprise a single-level pump building with mechanical, electrical and disinfection systems, surge protection infrastructure, flow metering and advanced instrumentation and control systems. Civil grading, access roads, perimeter security and desert-compliant landscaping will be incorporated as site improvements.
As the JV lead, Granite will perform clearing and grubbing operations, structure excavations and backfill, form/place/strip of concrete structures, installation of access roads along the pipeline alignment, demolition and restoration of existing roadways and the full installation of all pump station structures and equipment, per the release.
“Through SNCP, we’re delivering a high-value, future-ready water infrastructure solution that supports the long-term needs of Southern Nevada,” said Don Sawyer, Granite area manager.
Preconstruction is slated for completion in December 2026, with construction scheduled to kick off in January 2027 and anticipated completion in January 2030
