Which section of Chapter 30 demands written approval from the owner for significant changes to plans or specifications?

The correct answer is found in Section 39N, which specifically outlines the requirement for written approval from the owner for any significant changes to plans or specifications. This section is particularly important to ensure that both the owner and the contractor are in agreement about major alterations that could impact costs, timelines, or the overall scope of the project. By mandating written approval, it helps to protect the interests of both parties and maintain clear communication and documentation throughout the construction process.

In the context of contract management and compliance, this section provides a governance framework that assists in preventing disagreements or misunderstandings that may arise from unapproved changes. Being clear about the necessity for written consent serves as an essential measure of accountability and fosters a collaborative environment in which all parties are informed and in agreement before proceeding with modifications that could significantly affect the project.
