Enhancing Information Flow in Construction: Integrating BIM and Lean Tools into the RFI Process

Abstract

This doctoral research addresses inefficiencies in the Request for Information (RFI) process within the construction industry by proposing a novel, BIM-Lean integrated RFI system. While BIM and Lean methodologies have been widely adopted, their integration into RFI workflows remains limited, leading to persistent inefficiencies in information flow and waste reduction. This research develops a streamlined RFI process designed to enhance communication, reduce delays, and improve project outcomes. Through a comprehensive literature review, the study identifies key challenges in the existing RFI process, including delays, cost overruns, and fragmented communication. Using a mixed-methods approach, combining grounded theory for qualitative insights and quantitative survey analysis, the study evaluates how BIM and Lean tools—such as the Last Planner System and Value Stream Mapping—can optimise RFI workflows. The core outcome is an enhanced RFI process, validated through industry workshops and focus groups, accompanied by a structured guideline for implementation. A prototype website was developed to demonstrate the integration of BIM and Lean principles into the RFI process, providing a centralised platform for RFI management, improved information flow, and structured issue resolution. While real-world implementation is yet to be conducted, the research establishes a strong theoretical and practical foundation for future adoption. These findings contribute to the knowledge base on BIM, Lean Construction, and RFI optimisation, offering a scalable, industry-driven framework to enhance construction project management.
