| Abstract |
Schedule and cost are the most important factors that controlled in construction projects and are interrelated with each other. So they need to be controlled integratedly, but practically they are controlled separately. The integration control of schedule and cost have many advantages because schedule management and cost management share many construction data and are repeated frequently and periodically. This paper proposes a method to integrate schedule and cost using quantity take-off in estimation phase. The method calculates the quantity of materials for the works of construction and the elements of a building on the basis of WBS(Work Breakdown Structure) and CBS(Cost Breakdown Structure). The quantity of materials for the works of construction is the base to create activities and a network, and the quantity of materials for the elements of a building is the base of cost estimation and resource allocation. The paper develops a software application to implement the use of the quantity take-off. Then, the application is verified by a case study. |
