ECC Expeditionary Constructors LLC

ECC Expeditionary Constructors LLC, a for-profit construction and environmental remediation firm based in Burlingame, California, operates as a prime contractor on full-and-open Department of Defense infrastructure and environmental restoration projects, with no subcontract footprint. The vendor holds no SBA set-aside certifications and competes unrestricted across all recent awards.

ECC's customer base is concentrated almost entirely with the Department of the Navy's Naval Facilities Engineering Command, which accounts for 10 of 12 awards (100% coverage by award count and 99.95% of combined potential value of $32.36 billion). The Department of the Air Force Civil Engineer Center places the remaining 2 awards, valued at $15 million combined. This concentration reflects ECC's positioning as a specialized DoD construction prime on large regional infrastructure vehicles rather than a diversified federal contractor serving multiple agencies.

ECC holds seven indefinite delivery contracts with NAVFAC and the Air Force Civil Engineer Center, anchoring its federal posture. The three largest vehicles are the Pacific Deterrence Initiative Multiple Award Construction Contract ($15 billion ceiling, ultimate completion September 16, 2033), the Design-Build Multiple Award Construction Contract for Guam 2025-2033 ($15 billion ceiling, ultimate completion September 9, 2033), and the Indo-Pacific MACC for Projects in the NAVFAC Pacific Area of Responsibility ($990 million ceiling, ultimate completion April 23, 2033). ECC also holds a $240 million RADMAC III Environmental Multiple Award Contract focused on radiological and hazardous waste remediation across a ten-state region (Alaska, Arizona, California, Colorado, Nevada, New Mexico, Oregon, Utah, Washington), with ultimate completion May 7, 2027. A newly awarded Hunters Point Demolition MACC ($999 million ceiling, ultimate completion February 4, 2028) and a $15 million Air Force Civil Engineer Center construction IDIQ (ultimate completion September 29, 2030) round out the vehicle portfolio. The Air Force vehicle has generated 1 delivery order; NAVFAC vehicles have generated 9 delivery orders.

Representative work includes a $116.3 million firm fixed-price delivery order from NAVFAC for construction of a multi-service complex at Andersen Air Force Base in Guam (ultimate completion November 11, 2028, under the Pacific Deterrence Initiative vehicle), a $5,000 delivery order under RADMAC III for environmental remediation work in San Diego (May 8, 2025, ultimate completion May 7, 2030), a $25,000 delivery order under the Guam design-build vehicle for work in Barrigada, Guam (September 10, 2025, ultimate completion September 9, 2030), and a $3,000 Air Force Civil Engineer Center delivery order in San Antonio, Texas (September 30, 2025, ultimate completion December 29, 2025). Activity consists of 10 awards in 2025 and 2 awards in 2026 year-to-date. ECC's capability footprint spans design-build and design-bid-build construction (buildings, warehouses, bridges, piers, wharves, airfields, fuel storage), environmental remediation and restoration (radiological and hazardous waste management, Installation Restoration Program support, Military Munitions Response Program compliance), and demolition services, all executed under firm fixed-price delivery mechanisms with no set-aside designation. The vendor competes exclusively full-and-open against other qualified contractors on regional DoD infrastructure vehicles, with no presence on civilian-agency contracts or small-business-reserved vehicles.
