In general, precast concrete (PC) construction is preferred to reduce construction time, improve the quality of buildings and reduce costs. This type of construction consists of in-plant or in-house production, transportation and on-site erection processes. However, the PC construction method based on in-plant production is less effective in terms of cost compared to an in-situ construction method. According to previous studies in Korea, in-plant production cost of PC members accounts for 75-77% of total cost of PC framework, transportation cost is 7-10% and erection cost is 15-17%. If qualitative in-situ production is possible, more than 10% of in-plant production cost and 7-10% of the transportation cost can be reduced, resulting in better cost competitiveness. Yet, in-situ production of PC members has complicated issues such as securing site traffic and resolving interference with other work. This study is intended to develop algorithms that can quickly establish a production layout plan by considering in-situ production factors affecting composite precast concrete members. Usefulness of the developed algorithms has been demonstrated through a case study. (C) 2014 Elsevier B.V. All rights reserved.
