SmithGroup in downtown San Diego's Columbia district anchors its West Coast healthcare, science, and technology practice on the sixteenth floor of 550 West C Street, operating as the regional studio for the longest continually operating architecture and engineering firm in the United States, founded in 1853. The San Diego office — opened in 2017 and expanded to 8,500 square feet in 2025 to house a growing staff of over 30 design professionals — shares the downtown institutional-design pipeline with M.W. Steele Group, both pursuing healthcare and higher-education commissions across San Diego County. SmithGroup's integrated model bundles architecture, MEP engineering, laboratory planning, and interior design under one contract, a single-source delivery that eliminated multi-consultant coordination on the San Diego County Sheriff's Crime Laboratory — a forensic facility housing three law-enforcement divisions under Title 24 security and evidence-chain-of-custody requirements. MEP engineering specifications for laboratory HVAC, fume-hood exhaust, and critical-power redundancy coordinate with electrical contractors, a technical handoff that connects SmithGroup's performance specifications to the commercial electrical work at All City Electric, Inc. on downtown institutional builds. The local portfolio's most technically demanding delivery is the Sharp Chula Vista Medical Center's next-generation hospital tower, a phased acute-care expansion requiring OSHPD-compliant structural design, infection-control ventilation zoning, and critical-system redundancy across an occupied campus.
