For a good estimate the, actual cost of the proposed work after completion should not differ by more then 5 to 10 % from its approximate cost estimate, provided there are no unusual, unforeseen circumstances. What is ESTIMATION? Estimation is the scientific way of working out the approximate cost of an engineering project before execution of the work. It is totally different from calculation of the exact cost after completion of the project. Estimation requires a thorough Knowledge of the construction procedures and cost of materials & labour in addition to the skill , experience, foresight and good judgment. NEED FOR ESTIMATE Feasibility 1. It help to work out the approximate cost of the project in order to decide its feasibility with respect to the cost and to ensure the financial resourc...
