Corporate campuses, research facilities, and residential subdivisions all take shape in Lisle, and each has to be documented against its approved plan at completion. A final as-built survey captures that finished reality, recording constructed elevations and locations. Pi Surveying prepares it so the project can move to municipal acceptance.
A final as-built survey documents the actual location and elevation of completed improvements and compares them to the approved plans. Municipalities, engineers and owners rely on it to close out projects and confirm compliance.
The Pi Surveying process — clear, sealed, and ready for your project.
The village of Lisle has about 24,223 residents across the Lisle and Milton townships in DuPage County. Wheaton is the county seat, and plats and easements for Lisle property are recorded with the DuPage County Recorder of Deeds. With the East Branch of the DuPage River running through the area, a final as-built survey confirms that grading, detention, and storm structures were built to the engineered design. Lisle’s acceptance of a finished development rests on that recorded comparison.
Where the DuPage River influences a site, precise constructed elevations matter for confirming the drainage and any flood-related design was built as approved. The as-built documents those elevations.
Municipalities commonly require one for permitted improvements of any scale, including campus projects, before acceptance. It is the record proving the work matches the engineering.
An Illinois Professional Land Surveyor performs and certifies it, which gives the closeout document standing with the reviewing authority.
