Del Mar Environmental & Construction Services Inc.

Del Mar Environmental & Construction Services Inc., doing business as Del Mar Environmental & Construction, is a minority-owned, self-certified small disadvantaged business and DOT-certified Disadvantaged Business Enterprise headquartered in Chula Vista, California, that provides geotechnical investigations, environmental site assessments, subsurface characterization, and infrastructure remediation services to Navy and Marine Corps installations as a prime contractor (93% of recent awards) and as a subcontractor on environmental remediation programs.

Del Mar operates predominantly under 8(a) set-asides on its core IDIQ vehicle with Naval Facilities Engineering Command but competes full-and-open on delivery orders issued against that vehicle. The vendor holds a single-award, competitive 8(a) IDIQ contract with the Department of the Navy (NAVFAC) valued up to $15 million through September 2027, covering geotechnical and environmental engineering services across the NAVFAC Southwest region (California, Arizona, Nevada, Colorado, New Mexico, and Utah). Recent prime work includes a $1.78 million A-E study for site data gap investigation and tank area assessment at Naval Air Station North Island in San Diego (June 2023), a $1.83 million architect-engineer study of landslide monitoring at Marine Corps Base Camp Pendleton (April 2023), a $992 thousand geotechnical engineering services delivery order for Marine Corps Air Station Martinez Lake in Arizona (September 2023), and a $566 thousand environmental investigation and radon site assessment at MCB Camp Pendleton (September 2023). The vendor also delivered a $182 thousand geotechnical investigation for the P-2505 Mess Hall at MCB Camp Pendleton under competitive 8(a) set-aside in September 2025, and an $80 thousand topographical and utility study delivery order at Naval Base Coronado under competitive 8(a) in April 2026.

Customer concentration is extreme: NAVFAC accounts for 69 awards and $44.1 million of the $78.7 million combined potential value (56% of total), with the broader Department of the Navy ecosystem (NAVFAC, Navy Installations Command, Marine Corps, Naval Sea Systems Command, and other Navy components) representing 92% of all awards and substantially all dollar value. Among the top parent vehicles, the NAVFAC-issued IDIQs dominate: Indefinite Delivery Contract N6247322D1012 carries 27 task orders and $11.8 million combined potential value, N6247317D4623 carries 30 task orders and $6.7 million, and N6247320D0054 carries 14 task orders and $915 thousand. The portfolio is weighted toward firm-fixed-price and cost-plus-fixed-fee delivery orders ranging from approximately $1.6 thousand (pump truck and manhole services) to $1.83 million.

Activity has declined from a peak of 16 awards in 2023 to 9 in 2025 and only 3 through April 2026, though combined obligated dollars remain substantial at $22.7 million (29% of combined potential value). Within the next twenty-four months, six awards totaling $1.6 million in potential value reach ultimate completion, representing a modest recompete cliff relative to the vendor's $78.7 million portfolio base. In its subcontractor role, Del Mar performs vegetation maintenance, fence installation, vegetation clearance, soil sampling, and equipment/waste removal support under primes including Trevet-Noreas JV LLC, Trevet-Bay West Joint Venture LLC, Noreas Aptim Environmental Remediation JV, and Bering Sea Eccotech LLC, primarily on Navy environmental restoration and groundwater monitoring programs. The vendor's subsidiary Del Mar-Trevet-JV LLC reflects joint-venture teaming with Trevet entities on NAVFAC-related environmental remediation work.

Del Mar's capability portfolio centers on subsurface investigations, geotechnical site characterization, seismic and fault rupture assessments, geophysical surveys, environmental site assessments, contamination remediation (particularly PFAS and chlorinated solvent treatment), groundwater modeling and resilience analysis, and infrastructure maintenance support. The vendor's service footprint across Navy and Marine Corps facilities in the Southwest is deep but geographically concentrated and customer-concentrated; the company has minimal diversification into civilian agencies, non-Navy defense customers, or geographic regions outside its NAVFAC Southwest region.
