Optimized scheduling method for office building renovation projects

摘要

Office building renovation works allow for dynamic schedule planning, which breaks traditional logical relationships among construction work tasks. Consequently, the duration of renovation projects can be shortened significantly through dynamic scheduling. However, there are limited studies addressing this aspect. Therefore, in this study, we developed a scheduling method for office building renovation projects enabling the creation of schedule alternatives and suggesting optimized schedules in terms of project duration and cost efficiency. The developed method was applied to an actual renovation project, and the following results were obtained: (i) The method could develop six schedule alternatives reflecting project conditions and improve their cost and duration performance by 14.83% to 23.17% through optimization. (ii) Specifically, the sixth and fourth alternatives could yield a 36.18% lower project duration and 63.54% higher cost performance, respectively, compared to the other alternatives. Using this optimized scheduling method, project owners and managers can successfully plan their renovation projects while satisfying the requirements in terms of the project duration and cost.
