HomeServicesAs-Built Surveys › Oak Brook, IL

Home to major corporate campuses and retail, Oak Brook generates significant commercial construction that must be verified against its plans at completion. The final as-built survey provides that verification, documenting where the improvements were actually built.

Oak Brook & DuPage County specifics

The village of Oak Brook has about 8,163 residents and, within DuPage County, is associated with the Proviso township designation used in county records. Wheaton is the DuPage County seat, and plats and easements for Oak Brook property are recorded through the DuPage County Recorder of Deeds. Because Salt Creek runs through the area, a final as-built survey confirms that finished grades and stormwater facilities were built as engineered. That confirmation is what allows the municipality to accept a completed Oak Brook development.

What Oak Brook-area clients say

Frequently asked questions

Large campus and retail sites carry substantial grading and stormwater work, and the village needs measured proof it was built as approved before accepting the improvement. The as-built provides that proof.

Where Salt Creek influences drainage, precise constructed elevations are needed to confirm the design was built as approved, which the as-built documents.

An Illinois Professional Land Surveyor prepares and certifies it, giving the closeout record its standing with the municipality.
