摘要

This study develops an integrated project delivery framework that combines Building Information Modeling (BIM) with Integrated Project Delivery (IPD) to improve the performance of large-scale oil pipeline construction projects. A mixed-method research design was employed, including a systematic literature review, expert consultation, model formulation, and validation through two real pipeline projects located in Tehran and Isfahan. The study identified and applied key performance indicators related to schedule efficiency, cost performance, productivity, coordination effectiveness, and rework reduction. The proposed BIM–IPD model was initially validated using the completed Tehran project, where its predicted outcomes closely aligned with actual project data and demonstrated noticeable advantages over traditional delivery methods. The model was subsequently applied to the ongoing Isfahan project to evaluate the added value of early BIM–IPD adoption. The results indicated significant improvements in planning accuracy, reduced schedule duration, enhanced productivity, and lower levels of cost deviation and rework. These findings consistently highlight the operational and economic benefits of adopting a structured, collaborative, and data-driven delivery approach. Overall, the research confirms that the BIM–IPD framework provides a more reliable basis for decision-making and offers measurable performance improvements for future pipeline construction projects.
