The CAD department use the engineered plans as the basis to coordinate and design the mechanical and plumbing systems within the constraints of the architectural layout, resolving design conflicts with other trades as needed along the way.

In addition to the coordination, the CAD department uses the newly coordinated model to generate our fabrication and spooling sheets for use in the fabrication shop.

“We can depend on Harold Brothers Mechanical from start to finish. They are always a team player and have earned the reputation as a premier subcontractor from performance, safety and quality with Callahan Construction.”
