So how do we achieve concrete results when the concept of BIM itself is so abstract and contradictory?

According to the literature, BIM consists in the design and construction coordination of an infrastructure project using 3D softwares. Yet, completing a BIM project goes far beyond just using a specialized software. The fact is that any BIM project will require some kind of reorganization of your project’s structure, as well as open-mindedness from all the stakeholders.

To help in following a structured and organized methodology, the buildingSMART alliance™ initative of the National Institute of Building Sciences (http://www.buildingsmartalliance.org/) has published an execution guide for BIM projects that’s available online (http://www.engr.psu.edu/ae/cic/bimex/)

This document divides the execution of a BIM project in four main steps:

1 - Identifying the BIM project’s objectives and the planned uses of the model;

2 - Mapping the processes – what to do and who’s doing it;

3 - Defining BIM deliverables and the exchange formats for each of them; and

4 - Develop the contractual terms, the communication channels and the quality control procedure.

This procedure is really extensive and leaves nothing to chance. It can seem long and tedious to adapt it to a specific project, but remember that it will save much time and misunderstanding. Also, it is up to you to use only the necessary chapters for a specific project. The authors really insist on the fact that it’s the first project that’s the longest – a large part of the documents will then be identical in many subsequent projects.

Each firm and each client who has put together its own BIM Project Execution Guide will then be able to partake in the discussion and reach an agreement much faster on the ins and outs of the project with the other stakeholders. This would eventually lead to more projects completed with a BIM approach.

Do you already have your BIM project Execution Guide? Are you ready to start the process that leads to one? Tell us about your experience and participate to the BIM community!
