Survey Works provides as-built surveys in San Antonio and across Bexar County for owners, general contractors, civil engineers, and utility contractors. An as-built survey documents where the constructed features ended up once the work is complete, capturing their real location, elevation, and configuration so the project record shows the built condition alongside the approved design.
As-built surveys are also called post-construction surveys. The deliverable is a sealed drawing plus a CAD file keyed to the project coordinate system, prepared by a licensed land surveyor, showing the built condition overlaid against the design with any deviations called out.
What a San Antonio as-built survey documents
Our crews capture the location and elevation of the features the scope requires, and on most San Antonio projects that means building corners, foundation edges, utility inverts, manhole rims, parking layout, and drainage structures. The survey ties to the same property lines and coordinate system the project was permitted against, so the closeout record matches the plat and the approved plans. Projects that need documentation at more than one stage, from foundation through final, can run the as-built as a staged effort across the build.
When San Antonio clients order an as-built survey
A commercial owner orders one ahead of the certificate of occupancy so the record shows the building sitting inside its permitted envelope. A civil engineer orders one to close out a grading or utility package and confirm the installed quantities match the plans. A utility contractor orders one to document tie-ins before the trench is backfilled. Around San Antonio the work concentrates where the building is happening, from infill and redevelopment near the Medical Center, Port San Antonio, and Brooks to new commercial pads in Live Oak, Selma, and Schertz.
Whether an as-built is required depends on the permit conditions and the jurisdiction, and when it is, the survey gets scheduled against the closeout date the project has to hit. Survey Works coordinates that timing with the contractor so the documentation is ready before the inspection date.
As-built surveys and as-built drawings
A land surveyor's as-built is sealed site documentation, tied to the property boundary and the project coordinate system, covering the foundations, utilities, grading, paving, and drainage that a closeout reviews. The same phrase also gets used for interior laser scanning and BIM modeling, which is separate work produced for architects and facility managers. When a permit, a lender, or a civil engineer asks for an as-built in San Antonio, the sealed survey is the document they mean, and it is the one Survey Works delivers.
Survey Works has run as-built scopes across Texas for over 10 years, from single-lot commercial builds to multi-acre civil packages, and on telecom sites the as-built pairs with the FAA 1A certification work we run statewide. Every project returns the data in the format the design team or the municipality requires.
For an as-built survey anywhere in the San Antonio area, Survey Works has the field experience to deliver the record the closeout requires.
