Stantec Consulting Services Inc.

Stantec Consulting Services Inc., a foreign-owned professional services subsidiary of Mustang Acquisition Holdings Inc., operates as a prime contractor delivering infrastructure consulting, architectural design, and engineering services to federal civilian agencies on a full-and-open basis, with no characteristic set-aside designation across its prime footprint.

Stantec's capability portfolio centers on facilities master planning, infrastructure modernization, environmental due diligence, and engineering assessments. Recent representative work includes a $4.9 million firm fixed-price delivery order from the Smithsonian Institution (awarded April 2026) for critical facility upgrades at the Hirshhorn Museum in Washington, DC; a $1.38 million delivery order from the Smithsonian (September 2024) for the Cooper Hewitt Master Plan update in New York; a $808 thousand delivery order from the Smithsonian (September 2024) to revitalize steam tunnels and piping systems supporting the National Mall facilities; and a $7.5 million multiple-award blanket purchase agreement with the International Development Finance Corporation (awarded October 2021, through September 2026) covering environmental and social due diligence, monitoring support, and specialized assessments for DFC-supported infrastructure and development projects. Work is performed across Washington, DC, New York, and international locations where DFC operates.

Customer concentration is bipolar by customer type but misaligned by dollar value. The Millennium Challenge Corporation leads by award count (16 awards, $53.3 million combined potential value), and the Smithsonian Institution is the second-largest repeat customer by volume (7 awards, $8.2 million). However, USAID accounts for the largest potential-value concentration: USAID Mexico anchors $800 million in a single award, and USAID's Bureau for Management, Pakistan, and headquarters operations combined carry $242.9 million across five awards. The top five customer agencies account for 76% of awards by count but 94% of combined potential value, signaling exposure to a small number of large development-finance primes and civilian museum operators. Stantec places work under five named parent vehicles: the Environmental and Engineering Consulting IDC (7 task orders, $22.3 million), an indefinite delivery contract (6 task orders, $8.2 million), and the Water, Sanitation & Irrigation Infrastructure Consulting BPA (4 task orders, $13.2 million).

The top NAICS categories are Engineering Services (18 awards) and Architectural Services (8 awards), with supporting work in administrative management consulting and environmental consulting. PSC coding reflects museum and facility infrastructure work (Architect and Engineering — Museums and Exhibition Buildings carries 7 awards) alongside management engineering and construction inspection services.

Activity shows episodic volume rather than steady growth: two awards in 2019, three in 2020, three in 2021, a gap through 2023, seven in 2024, and one in 2026 through mid-April. Only one award (the $4.9 million Hirshhorn delivery order) reaches ultimate completion within the next twenty-four months, limiting near-term recompete exposure. On SCI-reportable service contracts, Stantec appears exclusively as a named subcontractor to other primes — 6 SCI records across FY2022–FY2024, spanning 1.2 FTEs in FY2022 to 2.9 FTEs in FY2024. The Deloitte Consulting LLP sub awards shown (Energy Sector Support Activity work for USAID Jordan, totaling $9.6 million in incremental funding across two task orders) illustrate Stantec's role as a sub-deliverer of technical assistance and economic reform support.
