The adoption of Building Information Modelling (BIM) which offers integrated software and processes for digital delivery, is becoming imperative for the UK construction industry. Literature thus far is unclear if the benefits claimed by the industry are exaggerated for commercial reasons. Our exploratory study investigates how the benefits of adopting BIM can be quantified. The findings reported through a focus group of industry experts specialising in digital innovation offers a reality check at project/firm/sector level to scrutinize the benefits and costs of BIM. The key results offer four areas the construction sector could further investigate to report monetary benefits and costs of BIM. The study thus provides insight into how businesses can develop a robust but adaptable methodology for capturing BIM costs and benefits.
