The advanced version of eTakeoff can use extensions (assemblies) that have been provided by another source. In this case, the source is CSP Construction Technology. Because the user cannot change the default settings inside of an extension (assembly) I have provided two separate traces. One that meets the generally accepted specification of 110 pounds per square yard per inch of thickness (HMA Density = 145#) and one that is for higher density heavy duty usage of 115 pounds per square yard per inch of thickness (HMA Density = 153#).
These values can be changed by the user in any given measurement. The user can select which method he/she wants to use for calculations with the default set at pounds per square yard per inch of thickness.
