Stantec Consulting Services Inc.

Stantec Consulting Services Inc., a large Canadian-headquartered design and engineering firm, operates as a prime contractor across multiple federal agencies, delivering architecture, engineering, environmental consulting, and infrastructure design services on a full-and-open basis (98% of recent awards prime rather than subcontracted). The firm is foreign-owned and carries no small business certifications; it competes in unrestricted federal markets and does not pursue set-aside work.

Stantec's customer base is highly concentrated among civilian infrastructure and resource management agencies. The Department of the Interior's National Park Service National Office and Bureau of Reclamation jointly account for 140 awards (26% of the award count), anchoring $688.6 million in combined potential value. The Department of the Air Force Civil Engineer Center drives outsized dollar concentration—eight awards alone carry $1.35 billion in combined potential value, reflecting large-scale base design and infrastructure programs. GSA Federal Acquisition Service and the Department of Health and Human Services Health Resources and Services Administration represent $211.5 million and $172 million respectively. Across 87 customer agencies, Stantec demonstrates a mixed customer-concentration posture: by award count, the Interior agencies dominate; by dollar value, Air Force programs dwarf the portfolio, suggesting Stantec holds strategic design-build and master planning vehicles with defense facilities.

Capability portfolio centers on architecture and engineering design, environmental compliance and assessment, water resource management, and infrastructure condition evaluation. Representative work includes a $29.6 million definitive-contract award from GSA for architect-engineer services on a new U.S. Courthouse Annex in San Juan, Puerto Rico (awarded November 2022, performance through March 2032); a $7.55 million delivery order from the Bureau of Reclamation for technical support services on the Central Valley Project (awarded September 2025, completion September 2030); a $4.94 million firm fixed-price delivery order from the National Park Service for comprehensive reviews in Missoula, Montana (awarded April 2026, completion April 2030); and Long-Term Pavement Performance data collection for the Federal Highway Administration under a $15 million IDV (single-award, awarded July 2023, completion July 2028). Across SCI-reportable federal service contracts, Stantec invoiced $42 million from FY2022 through FY2025, with FY2025 showing $14.9 million across 28.7 FTEs, reflecting fluctuating staffing intensity on individual contracts. Government-paid hourly rates on SCI-reportable work ranged from $41/hr (entry-level administrative support) through a median of $199/hr (mid-level consultant/analyst roles) to $471/hr (senior engineer/subject-matter expert positions), indicating a broad internal labor band serving cost-reimbursable, time-and-materials, and labor-hour contract vehicles.

Stantec holds multiple significant IDIQs and BPAs. The firm's $30 million WEST LARGE IDIQ with the National Park Service (awarded January 2022, completion January 2027) serves as a workhorse for park infrastructure projects across the western region, with recent delivery orders addressing wastewater rehabilitation ($3.21 million), sewer replacement ($859 thousand), trail corridor design ($697 thousand), and Title III support across Yellowstone, Mount Rainier, Yosemite, and other parks. A $30 million Eastern IDIQ with the National Park Service (awarded June 2022, completion June 2027) covers architectural and engineering services for facilities throughout the eastern United States, including historic preservation work. The Bureau of Reclamation awarded a $45 million multiple-award IDC on December 21, 2023, for architect-engineering services through December 20, 2028, supporting dam safety, water infrastructure, and feasibility studies. GSA placed Stantec on a $400 million nationwide general architect and engineering professional services multiple-award IDIQ (awarded March 20, 2026, completion March 19, 2031) under Executive Order 14398. The U.S. Army Corps of Engineers Savannah District awarded a $240 million multiple-award IDIQ for general design services (awarded May 31, 2024, completion May 31, 2029), under which Stantec has executed $4.52 million, $2.87 million, $1.55 million, and $1.06 million delivery orders for military construction and facility projects at Fort Stewart, Hunter Army Airfield, and Fort Liberty, Georgia and North Carolina. The Corps' DSMC National Dam and Levee Safety program awarded Stantec a single-award $49 million IDC focused on geotechnical services (awarded December 31, 2025, completion December 30, 2030). Stantec also holds a $500 million multiple-award MATOC with the Army Corps of Engineers Baltimore District for multi-discipline architect-engineer services (awarded July 31, 2026, completion July 30, 2031), a $37.8 million multiple-award IDC with the Millennium Challenge Corporation (awarded January 8, 2024, completion January 7, 2029), and $50 million in blanket purchase agreements on GSA schedules for environmental and historic preservation compliance technical support (awarded July 2, 2023, completion July 1, 2028). Stantec maintains a $15 million Federal Highway Administration BPA and participates in the Professional Services Schedule and Multiple Award Schedule vehicles, with 152 and 88 task orders respectively generating combined potential value of $131.1 million and $210.7 million.

Environmental consulting, engineering services, and remediation work dominate the NAICS distribution: 228 awards fall under environmental consulting (NAICS 541620), 177 under engineering services (NAICS 541330), and 104 under remediation services. Architect and Engineering work spans multiple PSC categories, with General design (85 awards), Other environmental services (79 awards), and Special studies/analysis environmental assessments (45 awards) most prevalent. Stantec's federal footprint reflects a large, diversified professional services profile anchored in infrastructure design and environmental compliance for civilian infrastructure and defense facilities.

Activity has been volatile year-over-year: 20 awards in 2022, climbing to 62 in 2024, then moderating to 35 in 2025 and 31 in 2026 (through September). Fifty-one awards (combined potential value $61.5 million) face ultimate completion within the next twenty-four months, creating near-term recompete opportunities for competitors and requiring active pursuit and extension negotiations by Stantec.

On SCI-reportable prime contracts, Stantec self-performs approximately 98% of contractor hours, engaging named subcontractors for only 2% on average—a prime-dominant delivery posture. Named subcontractors appearing across the SCI dataset include four firms, reflecting Stantec's preference for integrated internal delivery teams over deep subcontractor networks. The firm's corporate structure is a subsidiary of Mustang Acquisition Holdings Inc., a foreign-owned for-profit parent headquartered in New York.

Stantec's federal positioning is that of a large, full-and-open prime contractor specializing in architecture, engineering, environmental compliance, and water resource infrastructure work across civilian and defense agencies. The vendor competes on vehicle vehicles (IDIQs, BPAs, GSA schedules) rather than through set-asides, maintains broad geographic and customer-agency reach, and executes work through internal teams with selective use of specialized subcontractors.
