Survey Works provides form surveys in San Antonio and across Bexar County for concrete contractors, general contractors, production builders, and construction managers. A form survey verifies the position and elevation of the concrete forms after they are built and before the pour, so a layout or elevation problem gets corrected while the forms are still wood and the fix is still cheap.
San Antonio builders also call this a form board survey or a pre-pour survey. The deliverable is a sealed report and exhibit, prepared by a licensed land surveyor, documenting the form position against the approved site plan and calling out anything that needs attention before concrete is placed.
What a form survey checks before the pour
The crew documents the form walls, corners, top-of-form elevations, and slab-edge offsets against the control network, the property lines, and the approved site plan, with anything out of position called out before concrete is placed.
"A form survey catches elevation and layout deviations before the pour. If those same issues are discovered after placement, you're looking at concrete removal, rework, and schedule delays. In structural foundation work, the cost difference between early detection and post-pour correction can be a large delta."

That delta is the argument for the checkpoint. Catching a deviation while the forms are still wood means the carpenters adjust and the pour stays on schedule, while the same deviation found after the concrete cures means demolition, rework, and schedule impacts on every trade behind the foundation.
When San Antonio builders schedule a form survey
A concrete contractor schedules one after the formwork is complete and before the concrete crew arrives. A general contractor orders one where the slab sits close to a setback or an easement, since the pre-pour check is the last point where the foundation's position can be corrected before it becomes permanent. A structural engineer requests one where anchor placement or foundation geometry carries tight tolerances tied to steel or precast. On flood-sensitive parcels, the form survey confirms the finished floor will clear the required base flood elevation while the height can still be adjusted, work that pairs with an elevation certificate.
Form surveys on a production schedule
Much of the form survey work around San Antonio runs on production timelines, with builders holding pour schedules across subdivisions in Cibolo, Saint Hedwig, New Braunfels, and Seguin. The deliverable is turned around within 1-2 days of the fieldwork, so the construction team can adjust the forms and keep the pour on the calendar. After the pour, a foundation survey documents the as-poured result.
Survey Works has run form surveys across Texas for over 10 years, on commercial, civil, and residential foundation projects. Every project runs through the same process, calibrated to the tolerances and the pour schedule the construction team has to hold.
For a form survey, form board check, or pre-pour verification anywhere in the San Antonio area, Survey Works delivers the sealed report on a schedule that fits the pour.
