Stanley-Dowl JV

Stanley-Dowl JV, a for-profit joint venture based in Muscatine, Iowa, provides multi-disciplinary architectural, engineering, design, and construction management services to the National Park Service as a prime contractor (100% of recent awards), competing full-and-open with no set-aside designations across its federal footprint.

Stanley-Dowl JV operates almost exclusively under a single customer relationship with the Department of the Interior National Park Service National Office, which accounts for 25 of 26 awards and $452 million of the $452.6 million combined potential value across the vendor's recent federal portfolio. The National Park Service portfolio centers on utility system rehabilitation, water and wastewater infrastructure design, facility modernization, compliance services, and architectural and engineering support across geographically dispersed national parks. Representative work includes a $3.3 million delivery order for architect-engineer services to rehabilitate Hyde Street Pier at San Francisco Maritime National Historical Park (awarded June 2023, completing October 2025), a $2.8 million delivery order for rehabilitation of parkwide water and wastewater systems at Everglades National Park (awarded September 2022, completing June 2024), a $1.84 million design services task order for preliminary design, schematic design, and specifications at Glacier National Park (awarded March 2024), and a $1.09 million engineering services delivery order for utility and communication infrastructure rehabilitation at Canyonlands National Park (awarded September 2025).

Stanley-Dowl JV holds two parent vehicles: a $30 million single-award IDIQ for general engineering design services (contract 140P2021D0001) awarded by the NPS National Office in December 2020, which sustained 23 task orders totaling $22 million in combined potential value, and a new $400 million multiple-award IDIQ for nationwide general architect and engineering professional services (2026–2031) awarded April 8, 2026, under Executive Order 14398, which has generated one delivery order to date. The older IDIQ runs through 2024 and faces expiration; the new vehicle extends through April 7, 2031 and anchors the vendor's forward pipeline.

Activity has grown sharply: three awards in 2022 to eleven in 2024, but slowed to one award in 2025 and two in 2026 year-to-date (as of mid-October 2026). Only three awards (combined potential value $2.2 million) complete within the next twenty-four months, creating minimal near-term recompete exposure; however, the underlying $30 million IDIQ vehicle itself faces expiration and will require replacement. SCI-reported invoicing on federal service contracts shows $14.8 million total across FY2022–FY2025, with FY2024 peaking at $5.7 million across 9.5 FTEs and FY2025 holding steady at $5.3 million across 7.9 FTEs. Government-paid hourly rates on SCI-reportable contracts run a median of $242.61/hr, with senior labor reaching the 90th percentile at $436.88/hr and lower-tier support at the 10th percentile of $28.22/hr. Across SCI-reportable prime contracts, Stanley-Dowl JV subcontracts approximately 17% of total contractor hours to seven named subcontractors, including Poole Fire Protection (woman-owned small business) for fire protection engineering, Anchor QEA (small disadvantaged business) for environmental assessment and wetlands work, and Terracon Consultants for geotechnical services.

Stanley-Dowl JV does not operate as a subcontractor in the source data; all awards are prime contracts or IDIQs. The vendor's customer concentration is extreme — a single agency (NPS National Office) represents nearly 100% of recent award activity by both count and dollars. This concentration creates both a stable revenue base (NPS's ongoing infrastructure modernization needs across the National Park System) and a single-customer dependency risk. The new $400 million IDIQ (2026–2031) provides multi-year contracting capacity and suggests NPS confidence in the vendor's delivery; however, near-term activity has plateaued relative to the 2024 peak, and the approaching expiration of the legacy $30 million vehicle creates a critical recompete gate.
