Estimating construction costs

The determination of the cost of various items that would be required to carry out a construction project successfully is termed the estimation of construction costs. For preparing an estimate, the quantities of the materials are calculated from the construction drawings or blueprint design using formulas, and using these quantities, the construction cost estimating is done. The estimation process can be manual or it can be computed using construction estimating softwares such as RSmeans, STACK, and ProEst.
