ECC Constructors LLC

ECC Constructors LLC, a Burlingame, California-based limited liability company and subsidiary of Environmental Chemical Corporation, provides disaster recovery, emergency response, and debris removal services to the Department of Defense and Federal Emergency Management Agency as a prime contractor (100% of recent awards) on a full-and-open, non-set-aside basis. The vendor competes exclusively under unrestricted vehicles—no small business designations appear across the portfolio.

ECC Constructors operates across three $500 million-plus Advanced Contract Initiative (ACI) Indefinite Delivery Contracts with the U.S. Army Corps of Engineers (USACE), which anchor the entire footprint. These IDCs, awarded in 2021 and 2023 with performance periods extending through November 2026 and January 2028 respectively, provide rapid-deployment frameworks for debris removal, reduction, disposal, hazardous materials handling, and emergency response services across multiple USACE divisions in support of FEMA Public Assistance applicants following natural or man-made disasters. The three IDCs carry combined ceilings of approximately $3.584 billion. Work under these vehicles spans nationwide and territorial coverage: continental United States, Hawaii, Guam, and the Commonwealth of the Northern Mariana Islands.

Customer concentration sits entirely with the Department of the Army Corps of Engineers across district-level contracting offices. USACE accounts for 100% of the 42 awards in the source data and $6.13 billion in combined potential value. The Department of the Army Corps of Engineers (general/unspecified district) holds 14 awards worth $3.59 billion; the Los Angeles Engineering District (ENDIST Los Angeles) holds 9 awards worth $1.69 billion; the Honolulu Engineering District (ENDIST Honolulu) holds 16 awards worth $785.6 million; and the Norfolk Engineering District (ENDIST Norfolk) holds 2 awards worth $54.7 million. FEMA carries one award valued at approximately $10 million for submerged debris removal following Hurricane Helene. No concentration divergence exists between award-count and dollar rankings—USACE dominates both by volume and value.

Recent capability work clusters on three high-impact disaster responses. The 2025 California wildfires generated 15 delivery orders to ECC Constructors between January and May 2025, ranging from $59,204 for soil stabilization to $1.463 billion combined across two modifications (Eaton and Pacific Palisades debris removal support). The 2023 Maui wildfires generated eight delivery orders between September 2023 and January 2024, including a $373.3 million order for debris removal and disposal across 268 properties in Lahaina (delivered through February 2026) and a $210.4 million definitive contract for temporary debris storage site operation and private property debris removal (performance through March 31, 2026). Super Typhoon Sinlaku in the Commonwealth of the Northern Mariana Islands (May 2026) generated four orders totaling approximately $104.2 million for debris removal management, household hazardous materials collection, and e-waste operations in Saipan and Tinian. Hurricane Helene generated three orders between October 2024 and December 2024 totaling approximately $64.7 million for submerged and water debris removal at Claytor Lake and other water bodies in Virginia and North Carolina. The 2025 California wildfires also produced a $121.9 million hazardous site assessment order issued in January 2025 with completion targeted for August 2025.

Activity surged year over year—two awards in 2021, eleven in 2023, five in 2024, fifteen in 2025, and six awards through May 2026. Over 38% of the $6.13 billion combined potential value ($2.35 billion) has been obligated to date. The recompete cliff is negligible: only one award reaches ultimate completion in the next twenty-four months, carrying a potential value of $4 thousand. The three primary IDCs themselves expire November 2026 through January 2028, creating a material recompete window if USACE intends to continue the vehicle structure.

Service Contract Inventory records are sparse and not representative of the vendor's service-contract footprint; SCI captured $2.7 million in invoiced revenue across FY2025 under a single prime record with an unusually high hourly rate posture ($1,067.48/hr across all percentiles), indicating specialized labor or mobilization costs. The SCI dataset shows 97% of hours performed by named subcontractors—a signal that on this particular SCI-reportable contract, ECC Constructors managed subcontractor execution rather than self-performing. However, the bulk of ECC Constructors' federal work flows through delivery orders under the ACI IDCs and is priced firm fixed price, so SCI captures only a sliver of the vendor's total federal services activity and does not represent typical contract structure or labor composition.

ECC Constructors operates as a 100% prime contractor with no sub-award footprint in the source data. The vendor holds no parent contract vehicles, GWACs, or agency-wide IDIQs outside the three USACE ACI agreements. Work is performed entirely in-house or through subcontractor engagement on an order-by-order basis; the vendor does not appear as a named subcontractor to other federal primes in the source.

Environmental Chemical Corporation, the parent entity, is an employee-owned environmental remediation and construction firm also based in Burlingame. The subsidiary structure allows ECC Constructors to specialize in federal disaster response contracting while the parent maintains broader environmental and remediation capabilities. The subsidiary designation carries no SBA certifications or set-aside eligibility in the source.
