Construction Surveying in Florida

A boundary survey is typically the first survey needed. It establishes your legal property lines, setbacks, and buildable area. Without it, engineers cannot determine where improvements can be placed. For most projects, a topographic survey follows immediately — often done at the same time as the boundary survey to save costs. Together, these two surveys provide the complete data package your design team needs to begin engineering.

For a typical Florida residential construction project, budget $2,500-$6,000 for all survey phases combined. This covers pre-construction (boundary + topo: $1,300-$3,500), during construction (staking + form board: $700-$2,800), and post-construction (as-built: $500-$2,500). Commercial projects cost more due to ALTA requirements and larger sites. Using the same surveying firm for all phases saves 10-20% through package pricing.

Schedule construction staking after the site has been cleared and rough-graded, but before any building construction begins. The surveyor needs a clear, graded surface to set stakes accurately. Provide the approved site plan at least 3-5 business days before the scheduled staking date. For residential projects, staking typically takes 1 day of field work.

A form board survey verifies that concrete formwork is positioned correctly before the pour. The surveyor checks that the forms match the approved site plan for location, elevation, and alignment relative to property lines and setbacks. This is one of the most important quality checks in construction — a misplaced foundation cannot be easily fixed. The cost ($300-$800) is trivial compared to demolishing and repouring a foundation ($5,000-$15,000+).

Yes. Most Florida counties require an as-built survey as part of the certificate of occupancy (CO) process. The as-built documents that the completed construction matches the approved site plan — specifically setback compliance, finished floor elevation (in flood zones), and drainage grading. Schedule the as-built as soon as exterior construction is complete; do not wait for final landscaping.

Drones complement traditional surveys but do not replace them entirely. Drones excel at topographic mapping for large sites (faster and cheaper than ground surveys for sites over 5-10 acres), progress monitoring (repeated flights to document construction progress), and volume calculations (stockpile and earthwork measurements). However, boundary surveys, construction staking, and form board surveys still require ground-based precision instruments and a licensed surveyor setting physical monuments or marks.

Topographic survey data feeds directly into drainage design. Civil engineers use the contour map, spot elevations, and drainage feature data to model water flow, size pipes and retention areas, and design grading plans that ensure positive drainage. During construction, grade surveys verify that earthwork matches the approved drainage plan. At completion, the final grade survey confirms that as-built conditions will function as the engineer designed. Coordination between surveyor and engineer is critical — we deliver data in formats compatible with Civil 3D, ArcGIS, and other engineering software.

Yes. Properties in Special Flood Hazard Areas (SFHA) need an elevation certificate in addition to standard construction surveys. A pre-construction elevation certificate documents the existing grade relative to the Base Flood Elevation (BFE). Florida Building Code requires the lowest floor to be at or above BFE (with freeboard in many jurisdictions). A post-construction elevation certificate is required to verify the finished structure meets these requirements before the CO is issued. See our elevation certificates guide for details.

Survey involvement spans the entire construction timeline but each survey takes 1-5 days. Pre-construction surveys (boundary + topo) take 1-3 weeks and should be completed before design begins. Staking takes 1-2 days and happens when the site is cleared. Form board survey is done 24-48 hours before the pour. As-built survey takes 1-3 days after exterior completion. The key is scheduling each survey at the right point in the construction sequence — we coordinate with your contractor to minimize delays.

Keep all survey documents permanently: the original boundary survey (establishes your property lines), the as-built survey (proves construction compliance), any elevation certificates (needed for insurance and future sales), and the recorded plat if applicable. These documents are valuable for future additions, renovations, property sales, insurance claims, and permit applications. Digital copies are fine, but keep the original signed and sealed documents — they are legal instruments.
