Productivity in Construction

construction industry: labour productivity is the physical progress achieved per p-h, e.g., p-hs per linear metre of conduit laid or p-hs per cubic metre of concrete poured. The two most important measures of labour productivity are: • the effectiveness with which labour is used in the construction process;
