Which document lists the itemized content required for submitting a Contract Change Order Proposal?

The document that provides the itemized content required for submitting a Contract Change Order Proposal is the Supplementary Conditions. This section typically outlines the specific procedures and requirements related to changes in the contract, including how to submit a change order, the format it should take, and what information must be included.

Supplementary Conditions are essential because they tailor the general conditions of a contract to the specific needs of a project, often including additional requirements related to change orders. It ensures that all parties understand the expectations and processes for managing changes, which can help avoid disputes and ensure smooth project execution.

In contrast, the Project Manual encompasses various documents like bidding requirements, contracts, and specifications but is not specifically focused on change orders. Contract Specifications detail the quality and performance standards of materials and workmanship but will not usually address the submission requirements for change orders in detail. The Change Order Report is often a summary or record of changes that have occurred, but it is not a procedural document for submitting proposals.
