What should contractors do if they encounter a significant change in a project after it has begun?

When contractors encounter a significant change in a project after it has begun, the best course of action is to discuss the change with the client and amend the contract. This approach is crucial for maintaining transparency, ensuring clear communication, and protecting the interests of both parties involved.

By addressing the change with the client, the contractor can explain how the alteration may impact the scope, timeline, and budget of the project. This collaborative discussion allows for adjustments to be made in writing, which helps prevent disputes later on. Amending the contract formally documents the agreed-upon changes, providing a clear reference point for both the contractor and the client, which is essential for effective project management.

Continuing with the original plan disregards the reality of the situation, potentially leading to complications, delays, or conflicts. Reporting the issue to authorities may not be necessary unless there are legal violations or safety concerns, which is typically not the case for project changes. Completing the work without notifying anyone is risky as it can result in consequences for both parties, including financial losses and strained relationships. Hence, discussing the change and amending the contract is the most responsible and professional approach to managing alterations in a construction project.
