If a neighboring foundation is undermined during construction, what should the Contractor do?

The appropriate course of action when a neighboring foundation is undermined during construction is to prioritize the safety of people and property. This response is essential because undermining foundations can lead to structural instability, posing significant risks to nearby buildings, as well as to workers and passersby.

By focusing on safety, the Contractor will need to take immediate steps to stabilize the affected area, prevent further damage, and ensure that the site remains safe for ongoing activities. This could involve erecting barriers, providing temporary supports, or implementing site safety measures. Engaging with relevant parties, such as local authorities or construction safety inspectors, may also be essential in this context to manage the implications of the incident effectively.

While notifying the city, stopping construction entirely, or informing only the architect are important actions that involve communication and management, the immediate and paramount objective must be to assess and mitigate any danger to safety. Thus, protecting the safety of individuals and property takes precedence as the correct response.
