RTM Engineering Consultants maintains its San Diego-area office at 5250 Jackson Drive in La Mesa's Grossmont area, anchoring the West Coast operations of a national MEP, civil, and structural engineering firm established in 1981. Mechanical, electrical, and plumbing system designs produced at the La Mesa office feed directly to installation teams such as Jackson & Foster Heating and Air Conditioning for HVAC load-matched equipment sizing and ductwork layout. The firm holds engineering licenses in all fifty states and employs over five hundred staff nationally, with the Jackson Drive location housing approximately ten engineers and designers focused on California-market projects. Service lines include fire-protection engineering, commissioning, arc-flash coordination studies, sustainable-design and LEED consulting, lighting design, and building-technology integration. Power-distribution engineering for commercial and institutional projects specifies switchgear, panelboard, and conductor sizing through to the branch-circuit level, with field installation verified by local contractors like Balboa Electric. Healthcare-sector projects require compliance with OSHPD/HCAI essential-services standards, including NPC studies, emergency-power system design, and the microgrid configurations that produced six of the first OSHPD-approved microgrid installations in California.
