An As-Built survey is a record of location of the improvements “as they are built” during construction. The final location of construction improvements such as sewer pipes, buildings, utilities and pavement can be different than the original design location. Unforeseeable difficulties during construction may have required changes in the field to the original design. An As-built survey is a set of record drawings of the final location of the field changes for future reference. As-built surveys are needed to record variations from original Engineering plans to what is actually built. As-built surveys are required by many agencies to prove the location of a structure at a point in time. Many agencies need the as-built surveys for the actual locations of underground improvements.

Commonly performed on commercial and residential properties, an as-built survey shows the status of improvements to a piece of land as they appear at a particular point in time.

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.  An 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.

As-built surveys are surveys of existing facilities, usually shopping centers, schools, or factories. These surveys depict the location of all existing improvements on a site, including, but not limited to, buildings, parking areas, utilities, storm drainage systems, sewerage disposal systems, and any other features. An as-built survey usually involves the establishment of the site’s boundaries and the analysis of a title inspection report for the site.
