San Antonio Engineering Firm

A Full-Service Engineering Firm for San Antonio

Cleary Zimmermann Engineers is a full-service engineering firm serving San Antonio and South Texas, with capabilities that go beyond building MEP into industrial MEP, commissioning, IT/security design, and water/wastewater engineering. Our San Antonio team works from our headquarters office in the Southtown neighborhood — the same office the firm was founded from in 2006, and still our largest team more than 20 years later.

Most firms that call themselves “MEP” stop at mechanical, electrical, and plumbing. Cleary Zimmermann doesn’t. When a project needs commissioning verification, a security and access-control system integrated with the building’s electrical scope, or process-specific industrial engineering alongside standard building systems, we deliver all of it from one team instead of forcing you to coordinate multiple outside consultants.

Full-Service Engineering Capabilities in San Antonio

Every discipline below is handled in-house by our San Antonio team, which means fewer coordination gaps between consultants and a single point of accountability from schematic design through construction closeout.

• Building MEP Engineering: Mechanical, electrical, and plumbing design led by Thomas Watson, PE — HVAC systems sized for South Texas heat, power distribution coordinated with CPS Energy, and plumbing systems that account for Edwards Aquifer recharge zone requirements on applicable sites.
• Industrial MEP: Process cooling, specialized ventilation, and high-demand power distribution for manufacturing and processing facilities, led by Trey McDougall, PE, who brings substantial large-scale industrial project experience to the San Antonio market.
• Commissioning: NEBB-certified and ACG-certified commissioning services for all building types and scales — one of our most established service lines, with decades of Texas project experience behind it.
• IT/Security Design: Data infrastructure, access control, surveillance, and audio/visual systems, coordinated with the MEP scope from the start — a practice sharpened by San Antonio’s significant federal and military project presence.
• Water/Wastewater Engineering: Municipal water and wastewater system design and infrastructure engineering — a service line that sets Cleary Zimmermann apart from most firms that brand themselves as MEP-only.

Why San Antonio Clients Choose a Full-Service Engineering Partner

Bringing on separate consultants for MEP, commissioning, and security design creates coordination risk — three sets of documents that have to be reconciled, three different points of contact, and gaps that tend to surface during construction rather than during design. Cleary Zimmermann’s San Antonio team eliminates that risk by keeping every discipline in-house and coordinated from day one.

That breadth also means we scale with the project. A single building renovation might only need our building MEP team. A campus expansion with new security infrastructure and a commissioning requirement pulls in three of our practices working from the same set of drawings. As the firm’s headquarters market, San Antonio has the deepest bench of any office we operate — three dedicated principals, each leading a distinct practice area, all based in the same building.

Serving San Antonio and South Texas

Our San Antonio office isn’t limited to projects inside the city limits. As the firm’s largest team, we support projects across South Texas, West Texas, and the Gulf Coast — including New Braunfels, Boerne, Kerrville, Seguin, Laredo, Corpus Christi, and communities throughout the region where a local firm with institutional-grade MEP capability isn’t always available.
