Automated Layout Planning of Climbing Formwork System Using Genetic Algorithm

Layout planning of climbing formwork system is a prerequisite for executing efficient and cost-effective structural framework in a high-rise building construction. However, most of the formwork system layout is operated manually under heuristic approach of the supervisor, and thus is prone to errors that affect constructability of the entire construction. Furthermore, inflexibility of the current method to changes in building design also results in unexpected variability during system utilization. Automated formwork layout method that considers essential factors such as configurations on unit module of the form as an input data, information on building parameters for specifying possible areas of system installation, and configurations on working platform for optimal arrangement of unit systems can be suggested as an alternative to the current manual execution of formwork layout. Therefore, this study proposes an automated layout planning method of climbing formwork system by using genetic algorithm. The method developed in this study is to be utilized for reasonable decision making of the construction worker in control of the automated layout planning.
