According to BIM Addendum SS5.4, the standard of care is determined by what?

The standard of care in the context of the BIM Addendum SS5.4 is primarily determined by the governing contract or the relevant common law applicable to the project. This means that the expectations for performance and the level of diligence required are outlined in the contract the parties have agreed to, or alternatively, guided by general legal principles if not explicitly covered in the contract.

This framework provides a clear reference point for evaluating professional conduct and can help establish liability in case of discrepancies or issues arising during the project's lifecycle. It is essential for all stakeholders to be aware of these contractual obligations to ensure compliance and to effectively manage risk. The other options, while relevant in different contexts, do not provide the foundational basis for the standard of care, which is fundamentally rooted in contractual and legal terms.
