Material Engineer – cum – Geotechnical Engineer cum Geologist

Key Responsibilities:

1. Geotechnical Investigations

• Plan, supervise, and interpret geotechnical and geological field investigations including boreholes, trial pits, cone penetration tests (CPT), plate load tests, and field permeability tests.
• Assess subsurface soil and rock strata, groundwater conditions, and material properties for foundations, embankments, and pavements.
• Ensure sampling, classification, and testing of soil and rock are performed as per IS: 2720 series, IS: 2131, IS: 4464, and IRC: 78/112.
• Prepare and review Geotechnical Investigation Reports (GIR) including soil profiles, bore logs, and recommendations for foundation design, slope stability, and ground improvement measures.
• Advise on foundation types, bearing capacities, and safe allowable loads for bridge substructures and retaining structures.

2. Material Studies and Pavement Inputs

• Identify and evaluate construction material sources (borrow areas, quarries, sand sources, water sources) and ensure compliance with MORTH specifications.
• Conduct and interpret laboratory testing of aggregates, soils, bitumen, concrete, and steel as per IS/BIS and ASTM standards.
• Support the pavement design team in determining CBR values, subgrade properties, and layer coefficients.
• Recommend improvement techniques for weak subgrade and unsuitable material replacement.
• Prepare detailed Material Source Reports and Material Testing Plans with mapping and documentation.

3. Geological Assessment

• Evaluate terrain, lithology, geological formations, and groundwater conditions along the project alignment.
• Identify potential landslide-prone, subsidence, or erosion zones and suggest suitable mitigation measures.
• Provide geological inputs for tunnel alignments, rock cuttings, and slope stabilization (where applicable).
• Support in selection of bridge and tunnel alignments with respect to geological and seismic conditions.

4. Documentation and Coordination

• Prepare and review technical reports, charts, and design data sheets for inclusion in the DPR.
• Coordinate with survey, structural, and pavement teams for integrated design solutions.
• Ensure quality assurance of field and laboratory data and maintain complete test documentation.
• Review third-party lab results and ensure compliance with project quality plans.
• Participate in client and authority review meetings, presenting investigation findings and recommendations.
