We frequently take the lead role in renovation projects and coordinate all of the required engineering disciplines, submit the design packages to the state Fire Marshal for review, and submit the design documents to the local code review authorities. We work with owners, architects, and design-build contractors to provide complete mechanical and electrical engineering services throughout the states where we maintain licensure.
