As a registered design professional for the Department of General Services, CJL Engineering was awarded the design contract for this project. We provided mechanical, electrical, civil and structural engineering and design services for the repairs of the existing Capitol Complex Steam Tunnel. The repairs included several areas that are spalling, cracking, crumbling and leaking ground water in the tunnel. The scope of the project was to repair all the damaged areas in the concrete structure, remove abandoned piping, investigate and repair the hollow areas of the floor. Also included was the prevention of future damage by adding additional structural support as necessary.
