Abstract

Effective design management during the preconstruction phase has significant effects on project performance within the Architecture, Engineering, and Construction (AEC) sector. This research examines critical factors that impact the design outcomes at the preconstruction phase in the construction of infrastructure projects which affect the overall project performance. Using a sequential hybrid research approach that combines qualitative interviews and quantitative surveys, this study identifies ten crucial factors that influence project performance during the preconstruction phase. The relative importance index (RII) method is used to prioritise these factors, emphasising the most influential areas for enhancement. This study investigates the use of lean construction (LC) principles and tools to minimize the impact of these factors. These tools include integrated project delivery (IPD), building information modelling (BIM), last planner system (LPS), value stream mapping (VSM), target value design (TVD), set-based design (SBD), and choosing by advantage (CBA). Authors propose a comprehensive Lean Construction-based Risk Mitigation (LC-RM) framework to integrate these methodologies and enhance the design process during the preconstruction phase, thereby improving overall project performance. This research makes a valuable contribution to the field of construction management by providing practical recommendations for effective decision-making and lean practices during the preconstruction phase. It serves as a preliminary step towards improving construction management processes and has the potential to be further explored in future studies.
