What are BIM specifications?

The BIM specifications or BIM requirements document is part of the documents that govern a BIM process. It succeeds the BIM Charter and will be accompanied by the BIM Convention to frame a BIM project. Each of these three documents fulfills a more specific role in defining the processes of a BIM project.

With regard to the BIM CDC, this document specific to the project owner aims to explore in detail the objectives and expectations of putting a project into the BIM context. To do this, the BIM CDC will be inspired by the more global BIM strategy specified in the BIM Charter, and will apply it to the specificities of a project.

Thus, it will specify elements such as:

• The BIM objectives and use cases of the project;
• Project milestones and associated deliverables;
• The objectives and responsibilities of the stakeholders;
• The technical requirements of the model (georeferencing, tree structure, format, naming rules, control method, etc.)

Why produce a BIM requirement document?

Writing a BIM specifications document will allow the project owner to give guidelines and a working environment to project stakeholders, and in particular to the design project manager.

Specifically, these guidelines ensure the project management team effectively oversees the project and achieves its stated objectives and uses. This document is typically authored by the project owner, the project's BIM Assistant to the Project Owner (AMO), or internally by the project management team itself.
