Methods for Calculating Ductwork Labor
2019-11-05 8:29:09 Methods for calculating Ductwork Labor There are several methods to calculate ductwork labor cost however, we will cover three of the most commonly accepted methods that provide consistent and accurate results are: The Hours per Piece Method, The The Hours Per Lb. Method and The Hours per Square Ft method for specialty ducts (PVC, FRP, Fiberglass, Flex etc.). The Hours Per Piece method is based on the actual amount of labor that is required to fabricate or install each specific piece and type of ductwork, predetermined and applied to the various sizes and types of ductwork in a takeoff. On this basis variations in the size and type of each piece of ductwork fitting and duct are considered as part of the labor calculation formula. This method is based on labor studies for the various types and sizes of ductwork fabricated and the experience of the estimators knowledge of the sheet metal fabrication process and associated labor and installation. Production labor studies are most often used as the basis for determining labor cost. The important consideration with this method is that labor will vary, in some cases significantly with variations in ductwork type and size. The Pounds Per
