The purpose of the As-Built Survey – also commonly called a Physical Survey – is to show the property “as it is built” at a particular point in time. While a pre-construction survey is performed to document conditions prior to construction work being performed, the As-Built survey is conducted to show the current state of the site at various stages throughout the duration of a project. It also serves as a close-out document to verify that the work authorized was completed to plans and in compliance with all relevant standards and regulations.
An As-built survey builds upon the base map of a project and includes research at local agencies, ground-level topography data, and the documentation of visible site improvements. The advantage of this survey is that the new Base Map can be updated to show the current conditions of the site.
