Which document includes supplemental conditions to a construction contract?

The correct answer is AIA A201, as this document serves as a foundational framework that outlines the general conditions of a construction contract. It includes various provisions that govern the relationship between the owner and contractor, including responsibilities, roles, and procedures during the construction process.

Supplemental conditions are modifications or additions to the general conditions provided in AIA A201, which may be included to address specific project-related requirements and legal compliance. These supplemental conditions can cover a range of topics such as project-specific protocols, safety regulations, or financing stipulations. They are integrated into the contract documents to ensure that both parties are aware of and agree upon the specific terms that might differ from the standard general conditions found in AIA A201.

The other options do not serve the same function. The Owner-Contractor Agreement outlines the specific terms agreed upon by both parties but does not automatically incorporate supplemental conditions the way AIA A201 does. A Construction Change Directive is used for changes in the work after the contract has been executed but it does not include supplemental conditions. An Invitation to bid is simply a request for vendors to submit proposals for projects, and it does not contain contract language. Therefore, AIA A201 stands out as the comprehensive document that encompasses supplemental conditions
