Connected expertise.
Lasting commitment.
A Glendale engineering practice bringing mechanical, electrical, plumbing, civil, and fire protection design together since 2002.

The whole building.
From the beginning.
Building systems work best when they are designed together. We connect core engineering disciplines with in-house architectural and structural support, bringing a coordinated perspective to new construction and renovation.
Our work ranges from HVAC and central plants to power distribution, fire safety, and building energy analysis. Education, transit, commercial, and mixed-use projects bring different challenges; we approach each with attention to the building and the people who rely on it.
Founded in 2002 and led by President Sang Y. Lee, the firm combines continuity of leadership with multidisciplinary technical experience. William Lee, Director of Project Administration, supports project and contract coordination.
Based in Glendale, California, our professional registrations span Arizona, California, Colorado, Guam, Hawaii, Louisiana, Nevada, Oregon, and Washington.
