Implementation of Building Information Modeling (BIM), within the Public Procurement. A Model-Based Approach for the Construction Industry.

摘要

In the Construction Industry, especially in the Public Sector, the tendering, where thepreferred contractor is selected and the price agreed, is a very important step for thesuccess of a project. However, practice shows that usually there are problems and theprice rises up along the construction process not only due to errors in the project itselfor changes applied by the client, but also due to additional works and materials to beadopted which were not included or well described into the tender documentation. Anew modus operandi called Building Information Modelling (BIM) is emerging in theConstruction Sector to reduce usual mistakes of 2D paper-based management of theprocedures, thanks to a digital approach that is easier controlled and analysed. BIM canimprove the overall process, but its spread is more advanced in the phases after the tenderaward. The BIM adoption in the earlier stages has not yet been widely spread.
