Existing Conditions Documentation, otherwise known as Pre/Post-Construction Surveys, include detailed Photographic data of buildings and areas adjacent to construction sites.

Before any construction site Mobilizes, it is highly recommended to conduct an Existing Conditions Documentation of all adjacent properties that surround the Construction site. The Photographic Documentation will document existing conditions of the properties, Construction site, and determine where Crack Gauges may be required, as well as locations for any Vibration Monitoring recommendations or requirements. Performing a follow up Photographic Documentation after construction has finalized is also recommended.

Existing Conditions Documentations are also a common practice in any MTA subway properties that require Vibration Monitoring.
