Cost estimation of prestressed concrete beam and reinforced concrete slab construction

An interactive computer model has been developed for approximate cost estimation of prestressed concrete beam and reinforced concrete slab construction in high rise commercial buildings. A number of design variables like different structural schemes, grid sizes, number of storeys, grades of concrete, grid location and section of beams have been incorporated in the model to assess their effect on cost and quantities of constituents of concrete construction. The use of the model is recommended for comparative cost estimation to determine the effect of design parameters on structural cost; for approximate structural cost estimation of an overall project; for checking of estimates for structural works; for calculation of quantity index for structural schemes and system; for budgeting of materials and finally for use in various studies in building economics.
