Small sites under 5 acres typically run ₹15,000 to ₹35,000 per acre, while large industrial sites over 50 acres drop to ₹5,000 to ₹12,000 per acre for comparable deliverables.

Hilly terrain reduces daily survey productivity from 5-10 hectares to 1-3 hectares per day, which raises overall project cost by roughly 30 to 50 percent.

Generally yes, especially on larger sites, with drone photogrammetry rates around ₹1,200 to ₹3,000 per acre compared to ground-based methods that scale less efficiently with area.

A complete quote typically includes AutoCAD drawings, digital terrain model, contour maps, cross-sections, and control-point reports, ideally NABL-accredited where required.

Often quoted separately, ranging from ₹15,000 to ₹1,00,000 depending on site distance and accessibility, so confirm whether it is included before comparing prices.

Fixed costs like mobilization, ground control setup, and flight planning are spread across less area on small sites, raising the effective per-acre price.

Yes, standard 18 percent GST typically applies on top of the survey line items, and a quote excluding this will understate the final cost.

You can, but the resulting data will not meet survey-grade accuracy. GCPs surveyed with DGPS are what anchor the topographic model to real-world coordinates.

It typically means the deliverables, including AutoCAD files, DTM, and control-point reports, meet accreditation standards accepted by regulatory and engineering bodies.

Compare the exact deliverables, accuracy specification, contour interval, and whether GCP work, mobilization, and GST are included, rather than the bottom-line number alone.
