Blackburn Consulting

Blackburn Consulting, a Subchapter S Corporation headquartered in Auburn, California, delivers geotechnical engineering investigation, design, and field services to the U.S. Army Corps of Engineers as a prime contractor (71% of recent awards) and as a subcontractor on environmental remediation and water-resources projects. The vendor competes exclusively in unrestricted, full-and-open procurements with no set-aside designations across its current portfolio.

Blackburn Consulting's federal footprint is heavily concentrated with a single customer. The U.S. Army Corps of Engineers accounts for effectively 100% of potential value across all awards — specifically, the Engineering District Los Angeles commands $47.1 million across three awards (87% of portfolio value), while Engineering District Sacramento holds $317 thousand, and the broader USACE organization manages two additional awards valued at $1 thousand combined. The Environmental Protection Agency Region 9 represents one active award with no stated dollar value in the source. The customer concentration is both by volume (three of seven awards) and by dollars (the LA district alone carries nearly all potential value), reflecting a specialized vendor-customer relationship built on repeat procurement within a defined geographic engineering mission.

Blackburn Consulting holds a $46 million indefinite delivery contract (W912PL25D0020) with ENDIST Los Angeles, a multiple-award vehicle running through December 2029, which anchors the vendor's prime work. Three task orders against this IDC total $1.1 million in combined potential value. Recent delivery orders under the vehicle include a $626,389 firm fixed-price award for borrow site investigation, evaluation, and hydrogeologic design support at the Santa Margarita River Levee at Camp Pendleton (completion October 2026), and a $460,012 delivery order for geotechnical engineering design services on Santa Paula Creek and Ventura River projects (completion June 2026). A separate $316,880 purchase order from ENDIST Sacramento for geotechnical investigation and design services (completion November 2027) represents the vendor's expansion into the Sacramento district. Across these assignments, Blackburn Consulting provides geotechnical investigation planning, field drilling program coordination, laboratory soil-sample testing, and design documentation to support USACE water-resources and infrastructure-assessment missions in California.

Activity is early-stage and growing — two awards in 2024, four in 2025, and one in the first quarter of 2026 — with only two awards (combined potential value $943 thousand) completing within the next twenty-four months, presenting minimal near-term recompete exposure. In its subcontractor role, Blackburn Consulting provides drilling services to EA Engineering, Science, and Technology on an Argonaut Mine remedial investigation and feasibility study under EPA's Remedial Acquisition Framework, and geotechnical field services and design support (including laboratory testing and a dedicated geotechnical engineer) to the Tetra Tech–Black & Veatch joint venture on the Stone Lock Closure Structure project in West Sacramento, California. The vendor's capability portfolio centers on geotechnical site investigation, subsurface characterization, drilling program management, and hydrogeologic design for water-resources and levee-safety projects, with secondary exposure to EPA environmental remediation work routed through established primes.
