Environmental Services Honolulu District Area of Responsibility

The Department of the Army Corps of Engineers Engineering District Honolulu established this Master IDIQ for environmental services under a total small-business set-aside on May 22, 2020, with a shared ceiling of $49 million and a five-year ordering period that closed on December 29, 2025. The vehicle is now closed to new orders.

The work encompasses environmental assessments, environmental impact statements, hazard investigations, field investigations, site monitoring, risk assessments, environmental remediation and cleanup of hazardous and toxic radiological wastes, ordnance surveys and removal, and institutional controls education. Performance spans USACE Honolulu District's area of responsibility, including Hawaii, American Samoa, and the Marshall Islands.

Sixteen task orders totaling $23.9 million in potential value have been awarded under this vehicle, with $21.4 million (89 percent) already obligated. Ordering activity accelerated recently: three orders in 2025 (through August), two in 2024, and a peak of three in 2021. The distribution among primes is heavily concentrated. Engineering/Remediation Resources Group, Inc. holds five orders valued at $20.7 million combined, capturing 87 percent of total vehicle potential value. Dawson-Hdr Services JV, LLC holds seven orders but only $2.4 million combined value. NA Alii Consulting & Sales LLC and GSI Pacific Inc. each hold two orders with minimal value. All 16 orders fund Army Corps of Engineers projects within Honolulu District.

Despite the vehicle's advertised total small-business set-aside designation, task-order awards reveal 15 orders (94 percent) designated as unrestricted, with only one order (6 percent) designated as total small business. Task orders are firm-fixed-price with typical individual ceilings ranging from roughly $95 thousand to $9.5 million. The single largest award, the Aua Fuel Farm Seed Project (W9128A20D0006-W9128A20F0038), carried a ceiling of $9.5 million and is substantially obligated at $9.3 million, with performance extending through June 2025. Recent orders from August 2025 carry ceilings near $600 thousand to $1.1 million.
