Dynamic model in modular construction on high-rise residential buildings based risk manageability to increase project time performance

Modular Construction has been considered as an effective alternative to conventional high-rise buildings. It has gained an increasing attention amount of attention over the last few decades as a way to advance sustainable construction. Besides the many benefits of modular construction technology in high-rise building construction when compared to conventional methods, the application of a modular system requires the interaction of various activities. The modular system will change the relationship between activities that were originally independent of each other (conventional methods) to become interdependent, and the potential risk will certainly occur especially in high-rise buildings. Therefore, it is necessary to do research on risk management of modular construction in high-rise building. This research is focused on high rise residential building. This study aims to analyze the factors that influence risk manageability in high-rise residential building modular construction on cost and time performance and to build risk manageability modeling using System dynamics on high-rise residential building modular construction projects. Sixteen indicators were extracted from the literature review and specialist interviews to conduct a sustainability evaluation. A survey was submitted to case project developers, designers, supervisors, manufacturers and contractors in Indonesia. The tentative hypothesis is that risk manageability modeling using system dynamics in modular construction projects high-risk residential building can improving time performance. finally, policy recommendations for improvement are needed.
