Specify the outcome.
Then specify the survey.
A practical RFP checklist and free scope builder for EPC, infrastructure, real-estate, energy and public-sector teams procuring drone, LiDAR or ground surveys in India.
Weak briefs create
unverifiable outputs.
“Conduct a drone survey” is not a complete scope. It leaves the provider to guess the accuracy, coordinate framework, surface definition, deliverable structure and acceptance test.
A defensible brief starts with the decision, then makes accuracy and validation measurable. Sensor choice follows from those requirements.
Build a survey scope
your bidders can price.
Select the intended decision and project conditions. The builder creates a method-neutral draft you can copy into an RFP, then refine with your responsible survey and engineering team.
DRONE / GEOSPATIAL SURVEY — DRAFT SCOPE Decision: Topographic design Site: Infrastructure or development site Coordinate framework: Project CRS, vertical datum and benchmark to be confirmed Accuracy class: Engineering design. Specify horizontal and vertical acceptance criteria verified against independent checkpoints. Capture programme: Single baseline survey Required deliverables: - Orthomosaic - DTM and contours - CAD/GIS features - Accuracy report Minimum acceptance evidence: - Method statement and capture record - Control and independent checkpoint schedule where positional accuracy applies - Coordinate reference, units, transformation and geoid information - Coverage, gaps, occlusions and excluded-area register - File register, version, metadata and documented correction cycle The provider may propose RGB, LiDAR, GNSS, total station, terrestrial scanning, sonar or a combined method, provided the selected workflow satisfies the stated decision, accuracy, completeness and safety requirements.

DECISION & USE
State the engineering decision the survey must support: concept design, detailed design, quantity certification, as-built verification, inspection or monitoring.
AREA & CONDITIONS
Define boundary, corridor width, terrain, vegetation, access, airspace, operational constraints and any exclusion zones.
COORDINATE SYSTEM
Name horizontal datum, vertical datum, projection, geoid model, benchmark source and required transformation procedure.
ACCURACY & CONTROL
Specify horizontal and vertical accuracy, confidence level, GCP/check-point independence, control survey method and acceptance-test sample.
CAPTURE METHOD
Allow the provider to select RGB, LiDAR, GNSS, total station, terrestrial scan or bathymetry according to terrain, surface and output—not a preferred gadget.
DELIVERABLES
List required formats, scale, contour interval, point density, classifications, breaklines, CAD/GIS layers, metadata and report structure.
QA & ACCEPTANCE
Require completeness checks, residuals, independent check-point results, known limitations, coordinate verification and a documented correction cycle.
SAFETY & PERMISSIONS
Allocate responsibility for access, aviation permissions, risk assessment, method statements, traffic/site interfaces and emergency procedure.
DATA GOVERNANCE
Define hosting, access, retention, confidentiality, ownership, subcontractor controls, export restrictions and deletion requirements.
CHANGE & DELIVERY
Set naming, revision control, delivery schedule, recurring capture geometry, comparison dates and the person authorized to accept outputs.
Ask for evidence,
not adjectives.
| Requirement | Evidence to request |
|---|---|
| Accuracy | Independent check-point residuals and stated confidence level |
| Coordinate system | CRS, datum, geoid, benchmark and transformation note |
| Completeness | Coverage index, gap/occlusion statement and excluded areas |
| Surface/model quality | Classification method, artefact review and limitations |
| Traceability | Capture date, processing version, file register and revision history |
| Acceptance | Named reviewer, review window and correction cycle |
Open to procurement teams.
