Projects & Case Studies

Representative BTPL assignments — the requirement, the methodology and the deliverables. Case studies are published only after client-sensitive details are cleared.

What kind of projects has BTPL completed?

Bearing Technology Private Limited (BTPL) has completed survey assignments in 12 or more Indian states since 2009, covering more than 1,600 km of infrastructure corridor and more than 3,350 acres of mapped ground. The case studies below are drawn from that work. The most recent is a drone LiDAR and bathymetric survey of about 2.5 km² of the Ganga riverfront at Garhmukteshwar, Uttar Pradesh, for Hapur Zila Panchayat, ahead of the Garh Ganga Mela 2026; among the others are a 330 km greenfield canal alignment survey from the Odisha border to Rajahmundry, Andhra Pradesh, for Balaji Surveyors Pvt Ltd; the 310 km Bathinda–Bikaner railway doubling Final Location Survey for DIMTS; a 30 km combined UAV and bathymetric survey on the Mumbai High-Speed Rail alignment for Afcons; a 200 km bathymetric survey of the Imphal river; statewide DGPS ground truthing across Jammu & Kashmir including Ladakh for the Flood Control Department, J&K, through Suhora Technologies Pvt Ltd; 121 km of existing highway corridor in Odisha for NHAI, through Balaji Surveyors Pvt Ltd; a topographic survey of approximately 350 acres of the Delhi Zoological Park, with a Ground Penetrating Radar survey within the same campus, for CPWD; and a corridor survey of approximately 30 km from Sarai Kale Khan in Delhi to the Sonipat border in Haryana, for NCRTC, through Mega Engineers, Noida.

Each case study sets out what the client required, how BTPL surveyed it, how the data was processed and verified, and what was delivered. Use the filters to narrow the list by sector or method.
