IPD and BIM-focussed methodology in renovation of heritage buildings

Complexity in the sustainable renovation of heritage buildings requires adoption of more sophisticated technologies and project management models to deal with the contradiction between sustainable design and heritage values preservation, as well as enhancing process productivity and final performance. This research aims to assess the application of several Integrated Project Delivery (IPD) strategies and tools through Building Information Modelling (BIM), determining shared collaborative practices across the projects and the level to which the teams were able to implement the tools and processes effectively to enhance sustainability aspects and efficiency of renovating heritages. The research adopts a mixed methodology, Qualitative Comparative Analysis triangulating the collected data. An intensive review of related literature is carried out, besides data collection and analysis of four real-world heritage cases (in different contexts). The research study enables a comprehensive and systematic exploration of the potential use of IPD and BIM within the development of an analytical framework consisting of a set of defined variables including 50 criteria, classified into 15 categories, and grouped into five thematic strands (people, process, policy, technology, and product). The findings reveal that IPD and BIM simultaneous use allows integrating heritage values into holistic decision-making frameworks attaining high-performance outcomes in heritage renovations.
