Which document outlines the specific terms and conditions of a construction project?

A contract is the document that clearly outlines the specific terms and conditions of a construction project. It serves as a legally binding agreement between the parties involved, detailing aspects such as the scope of work, timelines, payment schedules, and responsibilities of each party. The contract also defines the rights and obligations, ensuring that all involved understand their commitments and providing a framework for resolving any disputes that may arise during the project.

In contrast, an invoice is primarily a billing document that requests payment for services rendered or materials supplied, but it does not detail the terms of the project itself. A proposal is an initial document that outlines an offer to undertake the work, often including preliminary scope and pricing, but it is not finalized until it becomes a contract. A change order is used to document any modifications to the work agreed upon in the original contract; it specifies changes in scope, cost, or schedule after the contract has been signed but does not encompass all terms and conditions set forth in the main contract.
