abstract={Mechanical, Electrical, Plumbing and Fire Protection (MEPF) design process in Engineering, Procurement, and Construction (EPC) project delivery faces process bottlenecks and coordination issues leading to delay and cost overruns. Yet, most existing research address these qualitatively without operational-level measurement frameworks. This research adapts the Metrics-Based Process Mapping (MBPM) framework for MEPF design, using swimlane diagrams to visualize cross-disciplinary workflows and to measure activity-level metrics. The classification and analysis of waste sources is carried out with a waste identification framework . A case study of the EPC healthcare project validates this approach across Fire Protection System (FPS), Public Health Engineering (PHE), Heating, Ventilation, and Air Conditioning (HVAC), and Electrical disciplines during the schematic and detailed design phases. Through process mapping, document analysis using Document Control Index (DCI) records, and stakeholder interviews, the study identifies how MEPF design effort is diverted to non-value-adding activities, such as waiting, rework from revisions, and extra processing due to complex workflows. This work identifies significant performance gaps and the sources of waste in design processes. The framework provides a simple yet quantitative approach that helps MEPF teams and EPC contractors identify the causes of design process bottlenecks and supports structured collaboration and early stakeholder engagement to enhance Lean implementation. },
