Precast construction is a time effective technique which consumes less time than cast-in-situ technique for execution. Savings of time in construction would compensate the overall profit for the owner. Precast technology achieves better concrete quality control with less wastage of materials. In this paper, G+3 commercial multi-storied building is planned and compared with the precast construction and cast-in-situ construction for cost analysis using Payback Period Method and Net Present Value

... ethod. Scheduling is done using Primavera. Primavera (P6) turn out to be competent tool in monitoring, scheduling, controlling and updating the project at any stage of construction process. Through payback period it is able to deduce that, the initial investment can be recovered approximately one month before the cast-in-situ method when we are employing precast approach. Also, considering investment criteria i.e. Net present value method shows that, a higher profit is obtained towards the investment in precast than in cast-in-situ method. Hence, precast construction method proves to be profitable when compared to conventional method of construction.
