About the company

Gwwo, Inc., a for-profit Subchapter S Corporation headquartered in Baltimore, Maryland, provides architectural, engineering, and technical services for historic preservation and cultural facility design to federal agencies as a prime contractor across 447 awards totaling $203.1 million in combined potential value. The firm competes exclusively in full-and-open federal procurement with no small business set-aside designation and operates entirely as a prime, with zero subcontract activity in the portfolio.

Gwwo's customer footprint is heavily concentrated with the Department of the Interior. The National Park Service National Office alone accounts for 101 awards ($94 million combined potential value), while NPS regional offices—the Northeast Region (82 awards, $16.6 million) and Southeast Region (55 awards, $20.2 million)—add substantial volume and dollars. Together, NPS accounts for roughly 77% of award count and 76% of combined potential value across the vendor's portfolio. The Smithsonian Institution ranks fifth by both metrics (37 awards, $13.1 million). The Army Corps of Engineers Engineering District Norfolk holds two awards valued at $10.1 million combined. This extreme concentration around interior and cultural-resources agencies reflects Gwwo's core market position in federal historic preservation work.

Capability delivery centers on architectural design, engineering assessments, and construction administration for historic structures and cultural facilities. Representative prime work includes a $3.008 million delivery order from NPS (November 2024) for removal of excess structures and abandoned buildings across a West Virginia park; a $1.75 million supplemental services order (July 2023) for predesign and schematic design work in West Virginia; a $1.163 million design services order (December 2023) for historic structure preservation in Maryland; and an $807.988 million order (September 2023) for development concept planning and environmental assessment of the Tidal Basin in Washington, DC. Smithsonian Institution work includes a $988.932 thousand order (September 2023) for window repair and blast-proof installation at the National Museum of Natural History, and a $1.262 million order (September 2025) for building exterior and rotunda laylight restoration at the same facility. Smaller task orders ($44,000 to $697,000 range) cover historic structure reports, site assessments, construction administration (Title III services), and facility rehabilitation across Independence National Historical Park, Shenandoah National Park, and Hampton National Historic Site.

Gwwo's primary parent vehicle is a $30 million, single-award indefinite delivery contract with the NPS National Office (September 2022–September 2027), which has generated 42 task orders valued at $17.3 million combined. Earlier NPS vehicles—Indefinite Delivery Contract C2000030700 (61 task orders, $36.3 million) and INP10PC60520 (53 task orders, $4.9 million)—anchor historic task-order volume. The Smithsonian Institution IDIQ (INP15PC00037) has issued 64 task orders worth $13.1 million. These vehicles enable Gwwo to deliver nationwide architectural, engineering, and technical services across multiple NPS sites and Smithsonian museums for cultural and historic preservation projects.

Activity per year shows volatility: nine awards in 2022, rising to 24 in 2023, then declining to ten in 2024, eight in 2025, and eight through late September 2026. Only thirteen awards (combined potential value $4.2 million) reach ultimate completion inside the next twenty-four months, suggesting limited near-term recompete pressure. Service Contract Inventory reporting captures $8.8 million in invoiced federal service-contract revenue across FY2023–FY2025 (SCI is a strict subset covering contracts above $150,000 and excluding goods, products, and micro-purchases): $848 thousand in FY2023, $4.8 million in FY2024, and $3.1 million in FY2025. SCI-reported FTE delivery ranged from 1.8 FTEs in FY2023 to 4.5 FTEs in FY2024 to 1.7 FTEs in FY2025. On federal service contracts captured in SCI, median government-paid rates ran around $249.77/hr, with senior labor pricing reaching the 90th percentile at $852.85/hr. Across SCI-reportable prime contracts, subcontractor hours averaged 2% of total contractor hours, with only two named subcontractors reported, confirming Gwwo's model as a self-delivery prime.
