About Larsa, Inc.
Larsa, Inc., a self-certified small disadvantaged business manufacturer of structural engineering software based in Melville, New York, operates as a prime contractor on a narrow and highly specialized federal footprint, delivering bridge design and analysis software exclusively to the Department of Transportation's Federal Highway Administration under total small business set-asides.
Larsa's federal work consists entirely of annual software license renewals for LARSA 4D Bridge Software, a finite-element modeling platform for segmental bridge analysis and design. The vendor's portfolio over the past five years comprises six purchase orders issued by FHWA between August 2022 and April 2026, with order values clustered at $23,400 to $24,000 annually. The most recent award, issued April 1, 2026, is a $24,000 firm fixed-price purchase order running through March 31, 2027, incorporating FAR 52.222-90 requirements for discrimination and diversity, equity, and inclusion compliance. Prior awards include renewal orders from 2023, 2024, and 2025 at identical or near-identical price points, and a $14,500 purchase order from August 2023 for general-purpose finite-element structural analysis software to support the agency's Office of Bridges and Structures. Performance is conducted at Larsa's facility in Ashburn, Virginia.
Customer concentration is absolute: FHWA accounts for 93% of awards (13 of 14) and 97% of combined potential value ($279,000 of $289,000 total). The vendor operates as a pure prime contractor with no subcontract exposure. Total obligated federal dollars across all awards equal combined potential value at $289,000, indicating full execution. Awards are categorized under Software Publishers (NAICS) and IT and Telecom Platform as a Service, Database, Mainframe, Middleware (PSC). Activity has been cyclical and low-volume — one award in 2022, 2024, 2025, and 2026; two in 2023 — with a twenty-year-plus relationship with FHWA dating to 2006 according to portfolio metadata. One award ($24,000) reaches ultimate completion within the next twenty-four months and faces recompete exposure in that window.
