Quinn Evans Architects Inc.

Quinn Evans Architects Inc., a woman-owned, full-and-open competitive architectural and engineering firm headquartered in Ann Arbor, Michigan, operates exclusively as a prime contractor on federal civilian cultural, park, and facilities projects, with 427 awards totaling $525.5 million in combined potential value across 25 customer agencies. The firm competes on an unrestricted basis with no set-aside designations, positioning itself in the open market for design, engineering, historic preservation, and infrastructure services to federal cultural institutions and the National Park Service.

The customer base concentrates heavily on three agencies that collectively account for 86 percent of combined potential value. The National Gallery of Art anchors the portfolio with 33 awards worth $216.5 million combined potential value, driven by a $200 million multiple-award Indefinite Delivery Contract effective through September 30, 2026 that funds architectural and engineering services including pre-design, schematic design, construction documentation, facility assessments, and historic structure reports. The Smithsonian Institution holds 88 awards totaling $115.3 million combined potential value under an unlimited-ceiling Indefinite Delivery Contract running through February 18, 2031 for multidisciplinary architect-engineer services covering habitat revitalization, mechanical system replacements, and major special construction projects. The Department of the Interior's National Park Service National Office awards 105 delivery orders valued at $103.3 million combined potential value under a $30 million single-award Eastern Region Indefinite Delivery Contract (effective through June 7, 2027) for architectural and engineering design services supporting historic preservation, facility rehabilitation, infrastructure upgrades, and cultural resource management across national parks, monuments, and sites in the Eastern United States and territories. Representative work under the NPS vehicle includes a $1.9 million delivery order for predesign and schematic design of communications, water, and sewer utility infrastructure at Mammoth Cave National Park, a $1.8 million delivery order for rehabilitation of historic structures and water line replacement at Gettysburg National Military Park and Cape Hatteras Light Station, and a $435,560 delivery order for schematic design services on the Dennison S project. Recent National Gallery of Art work includes a $2.9 million delivery order for architectural and engineering services, a $1.6 million delivery order for EB Study Center pre-design phase 2, and a $2.7 million delivery order for 7th Street Improvements design services.

Quinn Evans also holds a $10 million General Services Administration Region 5 multiple-award Indefinite Delivery Contract (awarded January 16, 2025, through January 15, 2027) covering Michigan for schematic design, pre-design, construction documentation, facility assessments, and infrastructure improvements for federal facilities, with the first delivery order of $676,189 issued in January 2026 to the Administrative Office of the U.S. Courts for design services on the Everett M. Dirksen Courthouse lobby hardening project in Chicago. The firm also competes under standing agreements with the Department of the Interior Southeast Region and the Federal Highway Administration on cultural landscape and historic preservation projects, including a $287,859 delivery order for water system replacement design at Fort Raleigh and Frisco in North Carolina and a $144,510 purchase order for cultural landscape inventory of Spout Run Parkway and George Washington Memorial Parkway in Arlington, Virginia.

The NAICS profile spans architectural services (255 awards) and engineering services (100 awards), with PSC coding dominated by architect-and-engineering general services (173 awards on landscaping and interior layout design; 117 awards on other general AE work) and specialized construction work (22 awards on museums and exhibition buildings). Work is performed across Washington, D.C., the Eastern United States, territories, and subordinate federal park and facility locations nationwide, with administrative headquarters in Ann Arbor, Michigan.

Activity has averaged 14 awards per year over the past five years, with 10 awards issued year-to-date in 2026. Recompete exposure within the next twenty-four months totals 22 awards worth $23.9 million in combined potential value. The Service Contract Inventory dataset reports minimal FTE delivery under SCI-reportable prime contracts (ranging from 0 to 1.9 FTEs across FY2022–FY2025), suggesting that Quinn Evans' federal revenue profile is dominated by firm fixed-price and labor-hours architectural and engineering delivery orders rather than labor-reimbursable service contracts above the SCI $150,000 threshold. Quinn Evans operates as a 100-percent prime contractor with no recorded sub-award activity in the source data, building its own in-house design and engineering delivery teams rather than relying on subcontractors.
