The aims of this study are to calculate the construction cost which is required in the implementation of method of precast and cast concrete construction in its place; calculate the required time in the construction method of precast and cast concrete in its place; analyze the quality of construction of precast and cast concrete method in its place and resulting in the K-250 of quality value. The selection of construction method is important in a construction project work because the right implementation method can provide maximum results, especially when it is viewed in terms of construction cost, time and quality. The construction of comparative cost selection method for In Situ and precast concrete materials uses Office of Highways Analysis 2010 Revision 3, implementation time uses S curve and construction quality uses questionnaire. Based on the result of construction cost plan of In Situ concrete construction of Rp. 109,790,340,000.00, the budget plan for the construction of precast concrete is Rp. 73.460.740.000.00. The calculation of the need for working time is In Situ concrete construction method needs 2 years 1 month and precast concrete construction method needs 1 year 8 months. The quality of precast concrete construction shows that the precast concrete surface is more neatly, better and more subtle than In Situ concrete. Field dimensions are safer and the quality of precast concrete is guaranteed as the sale of the product which is coupled with the concrete specified from the In Situ.
