PE-sealed concrete slab drawings for Fort Myers, Cape Coral, Bonita Springs, Estero and Lehigh Acres — foundation and soil-bearing design sized for Lee County, ready for Lee County's stricter high-wind plan review. Same-day quote, most packages complete in 5–7 business days.
A new concrete slab — for a room addition, shed, AC or generator pad, or outdoor kitchen — is foundation work, and in Lee County it needs a permit with PE-stamped drawings. We engineer the slab thickness, reinforcement and footings for your loads and your site.
In Lee County, most new slabs that carry a structure or equipment need a permit and sealed engineering. The design isn't about wind — it's about the ground: soil-bearing capacity, slab thickness, reinforcement, footing depth and a vapor barrier. The engineer sizes all of that so the slab won't crack, settle or heave. Confirm the specifics with Lee County's stricter high-wind plan review before you build.
Lee County typically has a high water table and coastal flood-zone requirements. That's why a slab package starts with the soil: presumptive bearing under the Florida Building Code, or a geotechnical report where conditions call for one. From there we size the slab thickness, the reinforcement and the footing depth so the foundation performs — the part Lee County's stricter high-wind plan review reviews most closely.
We prepare concrete slab permit packages across Lee County, including Fort Myers, Cape Coral, Bonita Springs, Estero and Lehigh Acres. Wherever your site is, the drawings are sealed for your address's exact conditions.
Franca Engineering prepares concrete slab permit packages from $1,500 — full PE-stamped drawings, foundation and load calculations for your Lee County site, and response to plan-review comments (re-sealing until approved is included). County permit fees are separate and paid to the building department.
Send your slab size, what it will support, and your address — we quote the same day and most packages are ready in 5–7 business days.
Start Your Project →In Lee County, a slab that supports a structure, an addition, or heavy equipment needs a permit and PE-sealed drawings. A small at-grade patio slab may be exempt, but the threshold is set locally — confirm with Lee County's stricter high-wind plan review before you pour.
It covers slab thickness, reinforcement (rebar or mesh), footing size and depth, and edge details, all sized for the load and for Lee County's soil conditions — a high water table and coastal flood-zone requirements. The sealed drawings and calculations are what the building department needs.
Engineering drawings are usually ready in 5–7 business days. Plan review through Lee County's stricter high-wind plan review then typically runs one to three weeks, faster when the package is complete and sealed on the first submission.
