BIM maturity assessment and certification in construction project team selection

摘要

To implement BIM in a construction project successfully, all the project participants, as BIM users, must have minimum BIM capabilities. Before any project starts, assessing the BIM capabilities of project stakeholders is a concern for construction clients. The main problem however is that they have no mechanism to ensure that the key participants they hire for a BIM project have the minimum capabilities (BIM infrastructure, processes and qualified resources) to participate in the design and delivery of a BIM project. The high variability of a firms' readiness to work with BIM may impose a high cost for the client and the most mature members of the supply chain. Therefore, construction clients need a way to ensure a minimum BIM maturity, such as a maturity audit to assess the BIM competency of potential project team members. From a client's perspective, "minimum BIM qualification" means "minimum capability to use BIM". The current BIM maturity models try to assess the BIM capability level of firms, but do not focus on BIM Uses. This research proposes a maturity model that focuses on the capability of firms for specific BIM Uses, while measuring their general BIM competencies. The research methodology is based on a review of literature and focus group discussions. Through literature review, the researchers proposed a BIM uses maturity model. Then, BIM experts discussed possible improvements. After an analysis of the discussion, the author proposed the resulting model. It is expected that by using this model, construction clients may achieve more BIM benefits through the selection of BIM qualified project team members, i.e. reduced cost, time, and increased quality of project.
