Which contract document must be signed by both the owner and the contractor?

The Standard Form Agreement is a legally binding contract that outlines the terms and conditions of a construction project between the owner and the contractor. This document typically specifies the responsibilities of each party, the project scope, payment terms, and timelines. Signing this agreement is essential because it creates a formal commitment from both parties, ensuring that all parties are aware of and agree to the project's expectations, legal obligations, and procedures for resolving disputes, should they arise.

While the other documents, such as the Project Plan, Payment Schedule, and Scope of Work, play important roles in facilitating the successful execution and management of the project, they do not require signature by both parties to be recognized as obligations. These documents often serve as supplementary materials that help define various aspects of the project but do not constitute a binding agreement on their own. The Standard Form Agreement, therefore, is critical in establishing the legal relationship and binding agreement between the owner and contractor.
