How we deliver

Scope & options

Corridor surveys are linear-reference datasets built around alignment, chainage, cross-sections, structures and right-of-way context.

DPR support combines survey evidence with discipline-specific design inputs; the survey is one workstream, not the complete DPR.

Pavement metrics such as IRI or rutting require calibrated methods beyond ordinary RGB mapping.

Explore 4 service variants

Road, rail, canal and pipeline alignment survey

Measure the proposed or existing linear route.

Each asset owner may impose access and survey specifications.

ROW and acquisition-survey inputs

Map route boundaries and affected parcels.

Land acquisition and title decisions remain with the authorised process.

Road asset and pavement-condition survey

Record road assets and surface defects using suitable systems.

IRI, rutting and other engineering metrics require the specified calibrated equipment; ordinary drone imagery is not a substitute.

Route alternatives and spatial suitability

Compare route constraints using available spatial evidence.

This is screening, not a statutory approval.

Useful to know

Terms, explained
Alignment
The horizontal and vertical route definition for a road, rail, canal, pipeline or utility corridor.
Cross-section
A measured slice across a corridor showing terrain, assets and levels.
DPR survey inputs
Survey information prepared for detailed-project-report design; the full DPR remains a broader engineering scope.
Does this include a complete DPR?

The base service supplies survey inputs for the corridor. A complete DPR needs separate design, traffic, geotechnical and discipline-specific scope.

Why do you need corridor width as well as length?

Length alone does not define coverage. Survey width, off-route structures and access conditions materially affect capture and processing scope.

Can the same survey support land acquisition?

It can provide spatial inputs. Revenue records, prescribed procedures and competent authority adoption are still required.

Can you inspect road pavement as well?

Visible-condition and asset mapping can be added. Calibrated road-condition measurements require a specialist method and vendor, separately confirmed.

Method & limitations

Define alignment length, survey width and required chainage/sections.

Combine surface, ground and utility observations where the route requires them.

Deliver engineering inputs; design and DPR approval remain defined in the agreed scope.

Each asset owner may impose access and survey specifications.

Land acquisition and title decisions remain with the authorised process.

IRI, rutting and other engineering metrics require the specified calibrated equipment; ordinary drone imagery is not a substitute.

Help me ask
  • What corridor width and section locations does the designer require?
  • Is this survey-only or part of a complete DPR commission?
  • Which utilities and affected parcels need to be included?
Use ordinary words. A short problem description is enough. Do not include confidential or security-sensitive information.
Start with state and district/city. Exact boundaries can be provided later through an agreed channel.Leave blank if unknown.
An estimate is acceptable. Leave unknown rather than inventing a measurement.Leave blank if unknown.
This is a preference, not a confirmed mobilisation or delivery date.Leave blank if unknown.
Personal addresses are accepted for civilian enquiries and individual training.
More project detail Optional
State only a non-sensitive reference. A submitted standard is a requirement to review, not a claim of accreditation.
Examples: ground-only work, no cloud hosting, limited access. Do not include personal IDs, confidential documents or sensitive locations.
An estimate is acceptable. Leave unknown rather than inventing a measurement.Leave blank if unknown.
Provide the tender/design requirement, not an invented target. Image resolution and positional accuracy are different.Leave blank if unknown.
Unknown is acceptable. Apply WGS84/UTM or a local benchmark only when it is confirmed for the job.Leave blank if unknown.
