About the company
Shannon & Wilson Inc., doing business as Shannon & Wilson Incorporated, is a geotechnical engineering and environmental consulting firm providing subsurface investigation, materials testing, geophysical surveys, and applied earth sciences services to federal agencies as a prime contractor (77% of recent awards) and as a subcontractor on large infrastructure projects. The firm operates without SBA set-aside designations and competes in the full-and-open market. Shannon & Wilson is a for-profit corporation headquartered in Seattle, Washington, with an operational subsidiary based in Anchorage, Alaska (the primary federal contracting location); the firm serves a geographically dispersed federal customer base centered on Alaska and the Pacific Rim.
Shannon & Wilson's federal footprint concentrates almost entirely with the U.S. Army Corps of Engineers Alaska District, which accounts for 51 of 71 recent awards (87% of award count, 99% of combined potential value of $44.1 million). The firm holds a $25 million multiple-award Indefinite Delivery Contract with USACE Alaska District (GEOTECH AE, awarded March 22, 2024, running through March 21, 2029) authorizing geotechnical design and related engineering services across Alaska, Hawaii, Japan, Korea, and the Pacific Rim. Under this IDC, Shannon & Wilson executes task orders for subsurface investigations, seismic analyses, groundwater studies, and environmental site assessments. Representative prime work includes a $954 thousand delivery order from the U.S. Air Force (ENDIST Alaska) on September 23, 2025, for geotechnical services at Eielson Air Force Base covering three projects with September 2026 completion; a $241 thousand delivery order from the Army on March 20, 2025, for geophysical survey work at Fort Wainwright; and a $200 thousand purchase order from the Department of Defense on September 11, 2025, for geotechnical services at Camp Cold Bay in Nelson Lagoon, Alaska. The firm also holds smaller positions with the Federal Aviation Administration (four awards, $401 thousand combined potential value) for geotechnical studies supporting RCAG and communication-tower replacement projects at Nome and Gulkana, and with the Federal Emergency Management Agency and the Department of the Interior. Vehicle utilization centers on five USACE Alaska District IDCs (W911KB08D0005, W911KB08D0007, W911KB24D0009, and others), collectively supporting 31 task orders.
Shannon & Wilson subcontracts as a geotechnical specialist to large A-E primes including HDR Engineering, Reid Middleton, AECOM Technical Services, and Kiewit Infrastructure West, performing geotech drilling, subsurface investigation, and testing/inspection services on civil and structural design contracts and construction projects. Notable sub work includes geotech services under Reid Middleton on two civil and structural A-E awards (March 2025 and April 2024), geotech drilling and engineering under HDR on a 35-percent-design contract at Joint Base Elmendorf-Richardson (January 2024), and testing and inspection support to Kiewit on runway extension work at JBER in 2022. Award velocity has ranged between two and ten awards annually over the past five years, with recent activity at eight awards in 2025 and two in the first half of 2026. Only two awards (combined potential value $290 thousand) face ultimate completion in the next twenty-four months, creating limited near-term recompete pressure on the existing USACE relationship.
