Stanley Consultants, Inc.

Stanley Consultants, Inc., doing business as Stanley Consultants Engineering And Architecture, is a multi-discipline consulting engineering and architecture firm based in Muscatine, Iowa, that operates as a prime contractor on federal architect-engineer (A-E) design and infrastructure projects across Department of Defense and civilian agencies, with no set-aside designations and a subsidiary relationship to parent company SC Companies, Inc.

Stanley Consultants competes full-and-open on full-sized programs and does not hold SBA certifications. The vendor's federal footprint consists of 974 prime awards (99% of the 983 total awards in the source) valued at a combined $2.45 billion in potential value, with $483.1 million obligated across all awards. Recent activity has contracted: award volume fell from 21 in 2022 to four in 2026 year-to-date, though the vendor remains active across large indefinite delivery contracts. The firm specializes in planning, design, permitting, construction management, program management, and alternative project delivery across energy, water, transportation, environmental, and military infrastructure sectors, with particular depth in Department of Defense facility modernization and overseas military installation development.

Customer concentration anchors to defense engineering. The top five agencies by award count cover 49% of awards, led by the Department of the Army (138 awards, $10 million combined potential value) and the Department of the Army Corps of Engineers Engineering District Middle East (127 awards, $572.9 million combined potential value). By dollar value, the ranking shifts: USACE Middle East drives $572.9 million (39% of combined potential value alone), followed by the Department of the Navy Naval Facilities Engineering Command at $322.1 million across 76 awards, and USACE Central at $32.2 million. The Department of the Interior Fish and Wildlife Service Region 3 (40 awards) and the Department of the Army Reserve Command (21 awards) round out the top five by count, though with lower dollar concentration.

Stanley Consultants holds and continuously draws task orders from multiple large USACE IDIQs. The Indefinite Delivery Contract W912ER04D0012 (Army Corps of Engineers) carries 55 task orders valued at $19.4 million combined; IDC INF07PC60244 (Naval Facilities Engineering Command) carries 54 task orders at $1.2 million combined; W912ER09D0001 (Army Corps of Engineers) carries 38 task orders at $28.4 million combined; and N6247019D5014 (Navy Installations Command) carries 35 task orders at $57.3 million combined. Recent IDC awards include a $49 million multiple-award IDIQ with USACE South Atlantic Division Mobile District for horizontal design program support (awarded April 1, 2026, performance through March 31, 2031), a $900 million MATOC with USACE Galveston District for planning and engineering design services (awarded December 8, 2025, performance through December 7, 2033), and a $240 million multiple-award IDC with USACE Middle East District for general A-E design services (awarded February 19, 2025, performance through February 18, 2030).

Representative prime delivery orders demonstrate Stanley Consultants' scale and geography. A $39.6 million delivery order from Air Force Civil Engineer Center (awarded September 28, 2022) covers PFAS engineering evaluation, cost analysis, and removal action studies at Tinker Air Force Base through September 29, 2027. A $21.3 million USACE delivery order (awarded September 27, 2022) supports design and engineering services for the LaGrange New 1,200-foot Lock project in Illinois, with ultimate completion July 30, 2025. A $19.044 million Navy ENDIV Transatlantic delivery order (awarded March 30, 2026) covers A-E services for facility requirements at Behaith Naval Base, Kuwait, through April 3, 2028. An $8.6 million Navy delivery order (awarded April 13, 2026) supports full design of the Kuwait Naval Force Ras Al Gaid Naval Base, with completion December 10, 2029. A $17.8 million USACE delivery order (awarded July 16, 2021) provides A-E design services for the United States Development Area program at Al Dhafra Air Force Base in the UAE through October 29, 2025. Work is performed worldwide (CONUS, OCONUS, and forward-deployed locations including Kuwait, Iraq, UAE, Spain, Iceland, and Italy) with administrative oversight at the Muscatine headquarters and subordinate locations as required.

Stanley Consultants operates as a prime contractor with selective subcontracting. Prime awards represent 99% of the award count, but the vendor regularly subcontracts specialized labor: across SCI-reportable prime contracts, an average 5% of total contractor hours are performed by named subcontractors, with three named subs reported. On named delivery orders, Stanley Consultants has engaged women-owned small businesses including Poole Fire Protection (women-owned, fire protection engineering), Bhdg Architects Inc. (economically disadvantaged women-owned, interior design and architecture), and GEO Consultants Corporation (women-owned HUBZone, civil and environmental engineering), as well as veteran-owned firms such as Anderson Engineering of Minnesota (veteran-owned, surveying and metes-and-bounds survey services). For larger infrastructure projects, the vendor also teams with larger engineering consultancies such as Tetra Tech and Stantec on civil works design, and specialized firms such as Austin Brockenbrough & Associates (petroleum, oil, and lubricant facility infrastructure) and Crawford Consulting Services (value engineering and cost/schedule risk analysis). On sub-awards under other primes, Stanley Consultants has worked for Tetra Tech (geotechnical and design support for lock and dam projects), Fluor Federal Services (technical assistance on federal disaster recovery programs), and Benham Design (microgrid design support). The SCI dataset shows only $465 thousand in invoiced revenue across four prime records over FY2022–FY2024 (roughly $310 thousand in FY2024 alone across 1.6 FTEs), indicating that SCI-reportable service contracts represent a very small slice of Stanley Consultants' total federal activity; the vast majority of work is procured as firm-fixed-price delivery orders for design and engineering services, which fall outside SCI scope.

Recompete exposure concentrates in the next twenty-four months: twenty awards with ultimate completion dates through mid-2028 carry combined potential value of $105.9 million, including task orders from the USACE Middle East District, Navy Installations Command, and USACE Galveston District contracts. The three largest-value IDIQs (USACE Middle East at $240 million, USACE Galveston at $900 million, and USACE Mobile District at $49 million, all awarded or recompeted in 2025–2026) present sustained pipeline but also competitive vulnerability if the vendor does not secure follow-on awards in upcoming recompetitions.
