Påsse, D; Disney, O; Roupé, M and Johansson, M (2022) Cost-estimation in construction: Building information modelling versus total BIM. In: Tutesigensi, A and Neilson, C J (eds.) Proceedings of 38th Annual ARCOM Conference, 5-7 September 2022, Glasgow Caledonian University, Glasgow, UK.
Abstract
Implementing Building Information Modelling (BIM) has been promoted to address cost overrun issues in the construction industry by improving the efficiency and quality of cost-estimation processes. Recently, the 'Total BIM' concept has emerged in Scandinavia, where the BIM is the legally binding construction document, 2D-drawings are excluded, and stricter BIM requirements are implemented. This paper highlights, explores issues, challenges, and opportunities within the cost-estimation process. Ten interviews were conducted with participants from traditional projects, involving the parallel use of BIM and traditional construction documents. An in-depth investigation of a 'Total BIM' project was also performed. Findings show that even in projects where BIM is present, traditional 2D-based methods were still used for cost-estimation due to a BIM's unclear legal status and lack of trust in BIM. 'Total BIM' may reduce cost estimation time by up to 90%, but issues regarding training, data and information management and education must be addressed.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
