HVAC, BUILDING AUTOMATION & ENERGY SYSTEMS
Mechanical engineering for commercial, institutional, and government projects across Washington and Oregon. Code-compliant, buildable, and fully coordinated across disciplines from design through construction.
OVERVIEW
Columbia Engineering Group provides mechanical engineering services for commercial, industrial, healthcare, institutional, and government projects throughout Washington and Oregon. From HVAC system design and building automation to industrial ventilation, energy analysis, and facility retrofits, we create practical, buildable solutions that support efficient construction and long-term performance.
More than calculations and equipment schedules, we provide coordinated engineering support that helps projects move smoothly through design, permitting, and construction. Our team works closely with owners, architects, contractors, and public agencies to reduce coordination challenges, improve system performance, and deliver permit-ready mechanical solutions.
