Building Information Modelling in Ireland 2025: A Retrospective Review of the BIM in Ireland 2019 Report

This paper presents a reflective study on the maturity of Building Information Modelling (BIM) in the Irish Architectural, Engineering, and Construction sector, building on previous research conducted in 2019. With the introduction of mandatory BIM requirements for the Irish public sector since 2024, the study evaluates the progress made since the last review to determine the industry's maturity in successfully working within these new requirements. The paper reviews the macro-BIM maturity models used in 2019 and examines existing literature post-2019 to identify what growth, if any, has been achieved within the five key areas of BIM diffusion. The findings indicate that while challenges related to resourcing persist, significant advancements have been achieved in the adoption of BIM standards and practices, driven by governmental and industry initiatives. The study concludes by highlighting areas needing further improvement in enhancing digital construction capabilities.
