As-Built Survey
DOCUMENTATION OF ACTUAL CONSTRUCTED CONDITIONS.An As-Built Survey documents the final locations, elevations, and configuration of completed improvements, providing a reliable record for project closeout, municipal review, operations, and future construction.
What Was Built, Measured Against What Was Designed.
Also called construction verification or a record survey.
The survey creates an accurate record of field conditions and allows the owner, engineer, contractor, or reviewing authority to compare the completed work with the approved design. Depending on the scope, the survey may document utilities, pavement, drainage features, grading, structures, retaining walls, site amenities, and other constructed improvements.
One Project, Both Pages.
The example below is a completed Eagle as-built for one commercial site, delivered as a two-page set. The first sheet carries the whole tract with its notes, legend, and flood information; the second steps into the building and the utilities. The field crew locates each feature in place, and the drafting team assembles these pages from those points.
Total Station, Scanner, or Drone. The Site Decides.
Eagle Surveying uses conventional survey equipment, GNSS, terrestrial laser scanning, aerial capture, or a combination of methods based on the type and scale of the project. We deliver the resulting information in the format required for engineering records, municipal submittals, owner documentation, or future maintenance and construction planning, and we perform as-built surveys across the DFW metroplex, Central Texas, and all of Texas.

From Closeout to the Next Project.
As-Built Survey FAQs
An as-built survey documents the actual horizontal and vertical locations of improvements after installation or construction. It may include utilities, pavement, drainage, grading, structures, retaining walls, and other site features. Owners, engineers, contractors, and municipalities use the information for project closeout, record drawings, regulatory submittals, operations, maintenance, and future expansion. The survey records field conditions; engineering acceptance remains with the appropriate project authority.
It changes project to project. The municipality may hold permit closeout until the as-built is submitted. A lender may want it in hand before releasing a final draw. The design engineer often needs the data for record drawings, and owners and general contractors keep the results for operations, warranty questions, and the next phase. Any one of them can be the reason the survey gets ordered.
Before the work disappears. Buried utilities are the classic example: once a trench is backfilled, the line can no longer be seen, so the crew visit is timed while it is still open, exactly like the storm drain shown at the top of this page. Improvements that stay visible can be surveyed any time after installation, and phased projects often set recurring visits so every stage gets measured before the next one covers it.
No. Staking comes first: the crew marks where the design says the work should go. The as-built comes after, capturing where the built work actually sits so the two can be compared. Many projects run one into the other, and the project control set for Construction Staking typically carries through.
Throughout Texas. The Denton office handles the Dallas-Fort Worth metroplex and North Texas, the Waco office handles Central Texas, and crews mobilize statewide when a commercial, industrial, municipal, or infrastructure project needs its finished conditions surveyed by a Texas registered surveying firm.
