Wilmington combines a riverside downtown with newer residential and commercial construction in southern Will County. As projects reach completion, the finished improvements have to be documented and compared to the approved engineering. A final as-built survey provides that documentation of the constructed improvements.
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.
Wilmington has a population near 5,700 and lies mainly in Wilmington Township, partly extending into Kankakee County, with Joliet as the Will County seat. The city sits along the Kankakee River, where FEMA Special Flood Hazard Areas make accurate as-built elevations particularly important for grading and floodplain review. For new subdivisions and commercial builds, engineers and city staff use the as-built survey to confirm improvements were constructed as designed before acceptance. Recorded plats and related documents for the Will County portion are filed with the Will County Recorder of Deeds. Every party is left with a verified account of how the finished improvements were built.
Because the river brings mapped flood hazard areas, accurate as-built elevations are needed to confirm that grading and finished-floor elevations were built to the design.
The plans show the intended construction, while the as-built shows what was actually built, including any field deviations in location or elevation.
Engineers, the municipality, contractors, and owners all benefit, since each relies on the verified record for compliance, acceptance, or permanent documentation.
