Tutor Perini Wins $651.8M Contract to Modernize Power Infrastructure on Naval Base Guam

Tutor Perini Secures $651.8 Million Naval Base Guam Contract for Power Infrastructure Upgrades

Tutor Perini Corp. has been awarded a $651.8 million federal contract to strengthen and modernize electrical infrastructure at Naval Base Guam, adding another major military project to the contractor's growing backlog and underscoring continued federal investment in strategic Pacific defense installations.

The project was awarded by the Naval Facilities Engineering Systems Command (NAVFAC) Pacific under the agency's Facilities and Infrastructure Multiple Award Construction Contract program. The work, known as Project P-1181, Harden Critical Feeders on Naval Base Guam, is designed to improve the resiliency and reliability of the installation's electrical system.

The contract will be executed through a joint venture involving Tutor Perini and its Guam-based subsidiary, Black Construction Corp.

Underground Electrical Upgrades Planned

The project calls for replacing existing overhead electrical distribution systems with underground circuit conductors housed in concrete-encased duct banks across Naval Base Guam. The improvements are intended to protect critical power infrastructure and improve service reliability for military facilities throughout the installation.

According to the company, design activities are scheduled to begin in August 2026, with construction expected to start in April 2027. Substantial completion is anticipated in June 2031.

The award will be added to Tutor Perini's backlog during the second quarter of 2026, further strengthening the company's portfolio of large-scale government and infrastructure projects.

Gary Smalley, Tutor Perini's CEO and president, said, "This new award represents our latest major project in Guam, and we are continuing to pursue various other significant opportunities there and throughout the Indo-Pacific region. We are pleased to continue supporting the U.S. government's infrastructure priorities, including those under the Pacific Deterrence Initiative."

Guam's Strategic Construction Pipeline Continues to Grow

Federal investment in Guam has accelerated in recent years as the U.S. military expands and modernizes its presence in the Indo-Pacific region. The Pacific Deterrence Initiative has generated billions of dollars in defense-related construction work, creating opportunities for contractors specializing in civil infrastructure, utilities, and military facilities.

Power resilience projects have become increasingly important for military installations, particularly in areas vulnerable to severe weather events and other disruptions that could affect mission readiness. Underground utility systems and hardened infrastructure are frequently incorporated into modernization programs to improve reliability and reduce operational risks.

For construction owners and contractors, the award highlights the continuing strength of the federal military construction market and the growing demand for specialized infrastructure expertise in the Pacific region. The long-term nature of the project, with completion expected in 2031, also provides sustained work opportunities for contractors and suppliers supporting defense-related construction programs.

Tutor Perini, headquartered in Los Angeles, provides civil, building and specialty construction services for public and private clients worldwide. The company has built a significant portfolio of transportation, military, utility and public infrastructure projects and continues to pursue major federal construction opportunities.
