Dynamic Model-Based Risk Manageability in the Modular Construction of High-Rise Residential Buildings to Improve Project time Performance

Modular construction has been applied in low-rise buildings over the past three decades, but its application high-rise is still less than 1% worldwide. Thus, need for residential applying modular Indonesia becomes very important. The unavailability of design guidelines disrupts life cycle projects. This study aims to analyze factors which affect risk manageability on-time performance building projects, then modeling using dynamic systems performance, results simulations and scenarios improve time performance. research variables were obtained based on a literature seeking opinions experts qualified this field. methods used cause flow diagram models developed into stock-flow diagrams with input formulation validation, thereafter carried out reviewed overrun. showed 15 that buildings. Without any mitigation risks, highest overrun 12.79 days was incurred due drawing approval, standardization days, supply chain 12.78 days. scenario #3 an optimistic alternative 53.55% improvement whereby project delays decreased from 126 days/25.25% 59.17 days/11.8%, delivering <20% could be implemented process.
