Look into the earth
before you build on it.
Raysense screens ground conditions before design freeze — seismic hazard, liquefaction potential, subsurface stratigraphy and soil response — so developers, EPC contractors and public agencies commit capital to sites that can actually carry the load.
Not sure which survey you need?
Answer four quick questions about your project and site — our Method Advisor recommends the right combination from our full survey and analysis catalogue.
🧭 Raysense Method Advisor
A quick, rule-based guide to the right investigation approach — not a substitute for a scoped proposal.
What are you trying to find out?
What sector is this project in?
What depth range matters most?
What's your timeline or deliverable?

This is a quick guide based on general practice, not a final survey design. Every recommendation is reviewed and adapted to your actual site conditions by our team before work begins.
Experience that's built to be trusted
Raysense is led by a senior technical team with over a decade of combined field and research experience in geophysics and geotechnical engineering. Our approach is research-driven by design — shaped by doctoral-level study and grounded in the same rigor we bring to every site investigation — translated into practical, code-compliant guidance you can act on with confidence.
Research-driven methodology
Led by Dr. Anurag Tiwari, whose doctoral research background grounds every study in rigorous, defensible methodology — not template reports.
Over a decade in the field
Our key personnel bring more than ten years of hands-on geophysical and geotechnical survey experience across India's varied terrain.
Code-compliant by default
Every study is built to satisfy IS 1893, IS 19235:2025, and the scrutiny of lenders, insurers, and regulators.
End-to-end capability
From regional hazard screening to field surveys, geospatial analysis, and in-house software — one team, one accountable point of contact.
Insurance pays after the damage. Screening prevents it.
Both are risk management. Only one of them stops the loss from happening.
Insurance
- Pays out after a structural or seismic event has already caused damage
- Premiums rise once claim history or hazard exposure is known
- Does not change what's built or where — only who absorbs the cost
- Deductibles, exclusions and claim disputes sit between you and recovery
Site screening
- Identifies liquefaction risk, weak strata and seismic hazard before foundation design
- Feeds directly into IS 1893-compliant PSHA/DSHA and structural sizing
- Lets you re-site, re-design or budget for ground improvement early — when it's cheap
- Produces a defensible technical record for lenders, insurers and regulators
Prevention has no deductible.
One picture of the ground, built from every angle
Hazard studies, geospatial & data services, and field surveys — each answers a different question about what's beneath a site.
Seismic hazard & geotechnical studies
PSHA / DSHA
Probabilistic and Deterministic Seismic Hazard Analysis — hazard curves, Uniform Hazard Spectra, and design PGA per IS 1893.
Soil response study
Site-specific ground response analysis using shear-wave velocity profiles to estimate amplification and design response spectra.
GIS hazard zonation
AHP-weighted GIS overlay of seismicity, faults, soil, topography, and land use into a composite suitability map.
Liquefaction assessment
SPT-based Liquefaction Potential Index (LPI) mapping and susceptibility classification across seismic zones.
Geospatial & data services
Geospatial analysis
Spatial data integration, terrain analysis, and thematic mapping for planning and hazard zonation.
Satellite imagery processing
Land use/land cover mapping, NDVI, change detection, and DEM generation for planning and agriculture.
Seismic data QC & processing
Noise attenuation, velocity analysis, migration, and attribute generation for exploration projects.
Petrophysical consultancy
Well log QC, lithology/fluid discrimination, porosity/saturation estimation, and net-pay evaluation.
Field geophysical surveys
Microtremor survey
Ambient vibration (HVSR) measurement for predominant frequency, Vs30, and site amplification.
MASW / LVL survey
Shear-wave velocity profiling and Vs30 site classification, active and passive methods.
ERT survey
Resistivity, SP and IP mapping for groundwater, fracture, contamination, and mineral exploration.
Drone survey
High-resolution UAV mapping — orthomosaics, DEM/DSM, 3D models, volume calculation.
GPR survey
Utility detection, void/cavity mapping, concrete evaluation, and shallow subsurface imaging.
How each method is applied
Working methodology sheets for our core assessment and survey types.
Across industries that build on, in, or under the ground
Construction & infrastructure
Foundation design inputs and seismic hazard studies for buildings and lifeline structures.
Oil & gas
Seismic data QC/processing and petrophysical consultancy for exploration projects.
Agriculture
Satellite imagery and NDVI analysis for crop monitoring and land suitability.
Roads & rails
Corridor mapping and geohazard assessment for linear infrastructure.
Groundwater & mineral exploration
ERT, SP and IP surveys to map aquifers and mineralization.
Geoenvironment
Contamination studies and environmental change monitoring.
Software built from our own methodology
Beyond consulting, Raysense builds tools that put our screening and hazard-analysis methods directly into engineers' hands.
Software
Site Screening Calculator
An interactive tool implementing our regional-to-site screening workflow — regional seismicity, fault proximity, estimated PGA, and site conditions combine into a suitability classification.
AutoLocate
Earthquake location software that automates hypocenter determination from seismic network data — built for rapid, repeatable location estimates.
PSHA Complete Suite
An end-to-end PSHA package — source characterization, GMPE logic-trees, hazard curve computation, and Uniform Hazard Spectra output.
Hardware
Field instrumentation
Raysense-built field hardware for geophysical data acquisition is currently in development.
Support our R&D
Your small contribution helps us keep investing in research and development — building better tools, refining our methods, and pushing our field forward. Every bit of support motivates the work behind Raysense.
Ground truth, before ground-breaking
Raysense Private Limited is a Delhi NCR-based geophysical, geotechnical and GIS site screening company, giving developers and engineers a clear, evidence-based picture of what a site can safely support — before design and construction decisions are locked in.
Dr. Anurag Tiwari
Consultant — Geophysical & Geotechnical ServicesDr. Tiwari leads the technical direction at Raysense, bringing over a decade of field and research experience in geophysical and geotechnical engineering, underpinned by doctoral-level research training. He oversees seismic hazard assessment, subsurface geophysical surveys, and site screening methodology across the company's project portfolio.
Standards and credentialing
IS 19235:2025
The relevant geotechnical services standard — compliance-based, not a stamp certification.
NABL accreditation
The correct accreditation pathway for a survey/testing services firm — not BIS.
GeM registration
Government e-Marketplace registration for public-sector procurement.
ISO 9001:2015
Quality management system certification — a recognized signal of process maturity.
