Geophysical Research & Consultancy Service (GRCS) was established in 1997 with the aim of providing consulting services in the field of engineering, environment, mineral exploration, groundwater research and geotechnical earthquake engineering.

The company has hardware and software to carry out following geophysical methods:

• Mulichannel voltage receiving equipment for Electrical Resistivity Tomography (ERT). It has high accuracy and high injection volatage (800 V) capable for deep investigation (200 m to 400 m depending on geological and topographical condition). Equipment for vertical Electrical Sounding (VES) and for Mise-a-la-masse tests.
• 24 channel seismograph with low cut freqency towards lowerside, suitable for Microtremor Array Measurement (MAM),  Multichannel Analysis of Surface Waves (MASW) and Seismic Refraction Tomography (SRT) along with high quality accessories. 
• Down The Hole Compressional and Shear Wave (DTH-PS) tests for shear and compressional wave velocity along borehole
• Broad Band Seismometer for Horizontal to Vertical Spectral Ratio (HVSR) for free field and structure resonnce frequency, and vibration monitoring .

GRCS has carried out above mentioned tests in hydroelectric projects, lanslides and critical slopes, railway and road tunnel, bridge foundations, building foundation and other community water sypply overhead tank foundations, groundwater potentiality evaluation and vibration monitoring of tunnel face blasting. Other activities of the company are geophysical application in glacier lake study projects and earthquake hazard mitigation. The company and its personnel have reputation of working in higher altitude and other difficult areas.

The principal geophysicist of this company Mr.Surendra Raj Pant has an established reputation within Nepal. He has 33 years of experience in this field. He has undertaken geophysical investigation in Nepal, Pakistan and China.

Without quality field data, good software and trained manpower it is impossible to produce reliable output of the geophysical investigation. The results of the geophysical mission largely depend on the interpretation capability of the geophysicist.  The company uses sophisticated software and inversion code to enhance the analytical capability and to improve the reliability of the result.
