Sheet Metal and HVAC detailers are responsible for sketching detailed drawings to help teams develop efficient and cost-effective production plans and tactics. These skilled commercial HVAC tradespeople provide coordination between the hardware fabricators and the installers to ensure success, quality and accuracy of projects from start to finish. Detailers work with project documents, plans and specifications, take field measurements and create 3-D coordination digital drawings with CAD computer-aided drafting (CAD) software.
