Multifactor productivity (MFP) is a more comprehensive in-dicator of productivity, which seeks to measure the efficiency with which capital, labour and intermediate products are con-verted into outputs. It is sometimes also referred to as total factor productivity. Whichever measure is used and, as Fig. 1 shows, it is.

The major factors that impact construction costs are materials, labor, equipment, overhead, and profit. The cost of equipment for civil engineering construction projects can range from 25 to 40% of the total project cost.
