How is a foundation protected during nearby construction?

Proper assessment of the existing structure, careful excavation technique, and in some cases specific engineering measures (temporary support, monitoring) are used to genuinely protect a nearby foundation during construction close to it.

Monitoring — periodic checks for any developing movement during the works — is a genuine practical measure sometimes used on more sensitive or higher-risk nearby construction, catching any issue early if one develops.

This is exactly why proper planning before construction begins matters, rather than treating a nearby existing structure’s protection as an afterthought once excavation is already underway.
