Keep long linear projects measurable from alignment to handover.
LiDAR corridor surveys, topographic mapping, construction progress, geotechnical investigation and asset evidence for highway and railway projects in India.
What makes this ground
consequential.
The project extends beyond one viewpoint
Linear corridors cross terrain, settlements, structures and access constraints that cannot be understood from isolated survey sheets.
Change accumulates between packages
Earthwork, structures, utilities and contractor interfaces progress at different rates and produce disconnected records.
Access and safety limit inspection
Active corridors, embankments, bridges and remote reaches make repeat ground access slow or hazardous.
Alignment and topographic survey
Controlled terrain, profiles, cross-sections, drainage and visible-feature mapping.
Aerial LiDAR corridor capture
Dense elevation evidence through complex terrain and selected vegetation conditions.
Construction quantities
Cut-and-fill, embankment and stockpile measurement against agreed baselines.
Geotechnical investigation
Boreholes, SPT, core logging, groundwater and laboratory records at planned structures.
Progress and asset inspection
Dated corridor evidence, bridge or structure observations and management reporting.
Evidence that enters
the operating workflow.
- Coordinated corridor base map
- Profiles, sections and terrain surfaces
- Traceable construction quantities
- Location-linked ground investigation
- Comparable progress and exception reporting
Rail investigation records remained traceable across locations.
Challenge
Multiple rail locations required comparable subsurface evidence under varied access and ground conditions.
Aerial solution
Boreholes, SPT, core logging, groundwater observation and laboratory testing were coordinated within one investigation register.
Result
The programme produced auditable field-to-report evidence for engineering review while stating coverage and limitations.
