Abstract

The purpose of this paper is to study the benefits of building information modelling (BIM) and determine the barriers to achieving these benefits. The use of BIM is not yet at a level where known benefits can be realised. This study consists of a literature review of the benefits of BIM and an empirical review, where focus group interviews were used to discover barriers. The major benefits of BIM include cost savings, better information flow, shorter project timelines and better quality. The greatest barrier is the lack of practical guidelines for BIM implementation in projects. Successful BIM implementation requires technology, people and processes to be in proper shape. Earlier studies identify the theoretical requirements of BIM implementation, but practical solutions are still not at an adequate level.
