Estimating concrete flatwork from aerial imagery

You estimate concrete flatwork from aerial imagery by tracing the pour area on a satellite view and multiplying it by a square foot rate that reflects thickness, prep, and finish. The map gives you an accurate area without staking the site, so you can bid before you ever drive out.

Trace the pour area

Outline the slab, driveway, or patio on the satellite view. For an irregular shape, follow the real edges rather than boxing it into a rectangle, so the area matches what you will actually pour.

Price the work, not just the surface

• Thickness drives concrete volume, so a four inch slab and a six inch slab price differently.
• Prep like grading, base, and forming adds labor the area alone does not show.
• Finish, from a broom finish to stamped, changes the rate per square foot.

Confirm the rest on site

Area is most of the estimate, but truck access, soil, and drainage can change the job. Capture those on the quote so the bid reflects the real conditions.
