We measure and map improvements as actually built, not as originally designed on the plans.
Buildings, pavement, drainage, and visible utility features are located with recorded elevations.
As-built conditions can be compared against approved plans to confirm what was constructed.
The sealed as-built supports project closeout, municipal acceptance, and permanent records.
Records the true field location and elevation of completed improvements rather than the intended design, so the record reflects what was actually built.
Many Chicagoland municipalities require a sealed as-built before final approval or occupancy; the survey provides the documentation those authorities expect.
Field measurements are checked against the engineered design so any deviations from the approved plans can be identified and addressed.
The survey is prepared under the responsible charge of an Illinois Professional Land Surveyor and carries a professional seal for use in the record.

Requirements commonly come from municipalities, permitting or engineering departments, lenders, title companies, and project owners closing out a project.
