Overview
Linear projects need a continuous, well-controlled survey along the whole route. We survey highways, railways, pipelines, canals and transmission lines with DGPS control, total station, drone and road and rail LiDAR.
For railways we work with total stations mounted on rail trolleys. For road DPRs we also carry out traffic volume counts (TVC).
What's included
- Control and TBMs along the route
- Centreline alignment survey
- Topographic strip survey of the corridor
- Cross-sections at the required interval
- Crossings: roads, drains, canals and utilities
Where it is used

How we work
- Recce and control along the route
- Alignment and strip survey
- Sections at set chainages
- Crossing details
- Drafting and checks
Questions
Can you work on live railway tracks?
Track surveys are done with the railway's permission and safety arrangements. We plan the work around their block timings.
Do you provide traffic volume counts?
Yes. Traffic volume count (TVC) and traffic surveys are available for road projects, DPRs and feasibility studies.
How long a corridor can you take up?
Any length. Long corridors are planned in sections with continuous control, so the drawings join without gaps.
