DA10--TileFlow Computational Fluid Dynamics Software Licenses and Maintenance (VA-26-00012826)

The Department of Veterans Affairs Technology Acquisition Center awarded a firm-fixed-price delivery order, number 36C10B26F0120, to Architecture Solutions LLC, a Service-Disabled Veteran-Owned Small Business. The contract, valued at $121,113.25, provides four TileFlow Computational Fluid Dynamics software licenses and maintenance. This procurement was executed as a sole-source acquisition via the NASA SEWP V GWAC under NAICS code 541519, citing the unique and highly specialized capabilities of the TileFlow software. The software is critical for thermal performance analysis and airflow modeling across approximately 170 VA data centers, supporting the Electronic Health Record Modernization initiative. The agreement includes a 12-month base period starting April 16, 2026, with four optional 12-month extensions, allowing for a total potential performance period of five years. Key requirements include unlimited technical support, software updates, and a shared floating license model. The use of TileFlow is mandated to ensure operational continuity and compatibility with nearly a decade of proprietary legacy .TLF models, as transitioning to alternative software would cause prohibitive costs and significant delays in VA Technical Reference Model approval. Acceptance is based on compliance with VA Technical Reference Model standards, including cybersecurity and Section 508 accessibility.
