Abstract

The construction industry continues to struggle with the persistent gap between design and construction. Integrated Project Delivery (IPD) has been introduced as a collaborative approach to improve integration and project outcomes. However, its use remains limited, mainly because of barriers identified in previous studies. This research seeks to highlight the most relevant obstacles to IPD and to examine strategies and practices that help overcome them, drawing on the experience of a real project. The study combines a systematic review of the literature with an in-depth case analysis of a complex building developed under a collaborative scheme in Peru. Barriers reported in the literature were organized, validated with expert input, and then compared with the strategies applied in the case study. Results show that cultural and mindset related issues are the most significant, representing about 28% of the barriers. The case demonstrates that these challenges can be reduced when stakeholders are involved early, supported by practices such as collaborative mockups, team co-location, and the use of digital tools, including artificial intelligence, to monitor progress. In summary, the findings suggest that consistent application of collaborative strategies can lower barriers to IPD and provide useful lessons for similar project contexts.
