STELL SIA SALAS O'BRIEN LLC specializes in engineering services for federal infrastructure and facility modernization, with deep expertise in capital asset management, seismic retrofitting, and facility condition assessments. The firm supports mission-critical upgrades for federal buildings by delivering full lifecycle engineering solutions—from RFP development and design-build procurement support to data hosting and asset inventory systems. Their technical capabilities include compliance with NIST standards, facility condition reporting frameworks, and integrated project delivery methodologies tailored to federal facilities. A key differentiator is their dual focus on structural resilience and regulatory alignment, particularly in high-risk environments such as VA medical centers and NIST campuses. The contractor maintains strong relationships with the Department of Veterans Affairs, where they support seismic upgrades and renovation planning for aging healthcare infrastructure, and the Department of Commerce, providing asset management services for NIST facilities. They also deliver facility assessments for HHS health sites and support GSA’s Federal Supply Schedule programs, demonstrating consistent engagement with agencies managing federal real property portfolios. Their primary focus is on NAICS 541330 (Engineering Services), where they translate complex building code requirements into actionable engineering deliverables for federal clients. They specialize in public sector facility modernization, with vertical expertise in healthcare infrastructure, federal laboratory environments, and federally owned buildings requiring seismic compliance and lifecycle documentation. As a Women-Owned Small Business and Service-Disabled Veteran-Owned Business Joint Venture, the firm leverages dual certifications to enhance its market positioning in federal procurement. Headquartered in Mountlake Terrace, WA, STELL SIA SALAS O'BRIEN LLC is strategically positioned to serve Pacific Northwest federal facilities while maintaining nationwide reach through its contract vehicles and technical teams.
