About Gwwo, Inc.

Gwwo, Inc., a Baltimore-based for-profit Subchapter S Corporation, provides architectural, engineering, and technical services for cultural and historic preservation projects as a prime contractor across 441 federal awards, competing predominantly in open (full-and-open) federal procurement without reliance on small business set-asides.

Gwwo's capability portfolio centers on historic preservation design, facility assessments, construction administration (Title III services), and sustainable infrastructure improvements for national parks and federal cultural institutions. Representative work includes a $3 million delivery order from the National Park Service for architectural and engineering design services to remove excess structures and abandoned buildings parkwide at a West Virginia national park site; a $1.26 million firm fixed-price delivery order from the Smithsonian Institution for restoration of the National Museum of Natural History building exterior and rotunda laylight; and a $988,933 Smithsonian delivery order for window repair, replacement, and blast-proof installation at the National Museum of Natural History, with completion scheduled for October 2026. The firm also delivers educational facility design services to the Department of Defense Education Activity, exemplified by a $96,305 definitive contract for construction phase services at Diamond Elementary School in Hinesville, Georgia.

Customer concentration is highly concentrated within the Department of the Interior. The National Park Service accounts for 76% of recent awards (337 of 441 awards) and dominates potential value: the NPS National Office anchors the portfolio with 99 awards worth $93.2 million combined potential value, the NPS Southeast Region carries 55 awards worth $20.2 million, and the NPS Northeast Region holds 80 awards worth $15.6 million. The Smithsonian Institution represents the second-tier customer with 35 awards worth $12.5 million. This concentration reflects Gwwo's position as the prime contractor on two dominant parent vehicles: a $30 million, five-year single-award IDIQ with the NPS National Office (awarded September 2022, running through September 2027) and a 10-year unlimited-value IDIQ with the Smithsonian Institution for multidiscipline architect-engineer services. The NPS IDIQ has generated 38 task orders worth $15.6 million; other named NPS parent vehicles include a Southeast A-E Services vehicle (39 task orders, $3.7 million) and multiple regional indefinite delivery contracts ranging from $4.9 million to $36.3 million in combined task-order value.

Activity shows a bimodal pattern. Gwwo received 9 awards in 2022, grew to 24 awards in 2023, then contracted sharply to 10 awards in 2024 and 8 in 2025, with only 2 recorded in 2026 year-to-date (as of mid-July 2026). Across the 441-award footprint, combined obligated dollars total $68.7 million (34% of the $200.8 million combined potential value), indicating substantial unexercised option value on task orders. Within the next twenty-four months, 11 awards carrying $3.5 million in combined potential value reach ultimate completion, presenting modest recompete exposure relative to the overall portfolio.

Service Contract Inventory reporting captures a partial view of Gwwo's federal service-contract activity above the $150,000 threshold. SCI-reported invoicing totaled $848 thousand in FY2023 and $4.8 million in FY2024, delivered across 1.8 and 4.5 FTEs respectively in those fiscal years. Government-paid hourly rates on prime SCI contracts ranged from a 10th percentile of $0.00 per hour (reflecting fixed-price task orders with blended cost allocation) to a median of $249.77 per hour and a 90th percentile of $852.85 per hour, consistent with senior architect and principal-engineer labor. Across SCI-reportable prime contracts, subcontractors accounted for an average of 3% of contractor hours, with 2 named subcontractors reported, indicating that Gwwo builds its own delivery teams and retains design execution in-house rather than functioning as a pass-through prime.

Gwwo's federal footprint is entirely prime work (100% of 441 awards), with no recorded subcontract activity in the source data. The firm holds no positions on government-wide acquisition contracts, blanket purchase agreements, or other multi-contractor vehicles; instead, the company operates as the sole awardee on two primary IDIQ relationships (NPS and Smithsonian) that dominate its federal revenue. This concentrated, prime-only posture reflects Gwwo's status as a specialized cultural and historic preservation architect-engineer firm with sustained past performance relationships rather than a multi-discipline prime competing across broad service portfolios or feeding into larger integrators.
