Which article of the BIM Addendum is primarily concerned with defining risk on projects?

The article that is primarily concerned with defining risk on projects is Article 5. This section emphasizes the identification, allocation, and management of risks associated with the project as it pertains to BIM processes. By clearly outlining how risks are shared among the parties involved, Article 5 plays a critical role in facilitating effective communication and collaboration throughout the project lifecycle. Understanding risk allocation is essential in BIM, as it dictates responsibilities and helps all parties proactively manage potential issues that could arise during construction.

The other articles and documents, while relevant to the BIM process and addressing other important aspects such as project delivery and collaboration protocols, do not specifically focus on the comprehensive understanding and definition of risks associated with the project. Thus, Article 5 stands out as the key resource for understanding how risks are structured and handled in the context of BIM.
