What is the difference between the Mechanical and Plumbing Cost Data books?
The Mechanical Cost Data book primarily covers HVAC components and controls, while Plumbing Cost Data covers plumbing fixtures and fire protection. The Plumbing book does include some small boilers and items that frequently are installed by plumbers. There is a large overlap in pipe and fittings between the two books. However, the Mechanical book does not include cast iron soil pipe. Both books include stainless steel pipe and fittings.
