From rail bridges in seismic zones to high-rise foundations in reclaimed soil, reliable sub-surface data is the first safeguard against cost overruns and structural failure. Monarch’s Geotechnical Investigation service delivers bore-logs, lab-tested parameters, liquefaction checks and ground-improvement advice that designers can plug straight into FEM and BIM models. Rotary coring, in-situ tests, seismic profiling and groundwater monitoring are all coordinated through a single QA plan, producing rock-solid design inputs and clear construction guidance.

Geotechnical investigations form an important part of extractive industries, such as open cast and underground mining, as well as hydrocarbon extraction. Furthermore, whether assessing rail bridges in seismic zones or high-rise foundations in reclaimed soil, reliable sub-surface data serves as the first safeguard against structural failure.

Monarch’s Geotechnical Investigation service delivers bore-logs, lab-tested parameters, liquefaction checks and ground-improvement advice that designers can plug straight into FEM and BIM models. Our capabilities include borehole drilling, standard penetration tests (SPT), cone penetration tests (CPT), seismic profiling, pressure-meter tests, and laboratory analysis of soil, rock, and groundwater samples. In addition, our team delivers detailed geotechnical reports covering bearing capacity, settlement analysis, slope stability, and foundation recommendations.

Where our investigations add value:

• Rail  & Metro – Bridge foundations, tunnel linings, depot yards

• Highways & Expressways – Flyovers, embankments, soft-soil ground improvement

• Ports & Coastal Works – Tetrapod revetments, sheet-pile walls, offshore piling

• Power & Energy – Dam abutments, switch-yards, wind-turbine pads

• Urban Real Estate – Deep basements, high-rise raft and pile systems

• Industrial & Mining – Conveyor galleries, stacker foundations, tailings dams

How we deliver:

A multidisciplinary field lab workflow links drilling crews, geologists, and geotechnical modellers in real time. Digital field logs capture sample depths and SPT blows; split-sampled cores are sent to NABL ready labs the same day; and cloud dashboards track recovery, RQD, and test status against the program. 3-D stratigraphic models integrate CPT, seismic, and hydro-geological data, allowing for early identification of clashes and problem areas before detailed design begins. Final reports provide foundation options, safe bearing capacities, settlement predictions, and construction staging advice all referenced to IS/IRC codes and ready for authority review.

Why Monarch has the edge: 

Owning the full fleet of rotary rigs, portable pontoons, and accredited laboratories means we can mobilize to city centres or remote riverbeds within 72 hours. Dual QA loops field re-logging of 10% of cores and duplicate lab testing ensure data repeatability within IS-code tolerances. Designers value the traceability: every SBC or modulus value links back to a labelled sample stored in climate-controlled racks throughout the project lifecycle. This rigor delivers a more than 98% first-submission acceptance rate for railway, highway, and port foundations

Representative projects:

• Pune Metro Underground Section (Agriculture College – Swargate) – 2 959 m of drilling, full lab testing and settlement modelling that informed tunnel-bore machine selection and lining thickness.

• Vijayawada – Guntur BG Line via Amaravati – alignment-wide boreholes, bridge geotech and Krishna river foundation study feeding a ₹ 305 million DPR.

Monarch’s subsurface insight turns unknown ground into design certaintykeeping budgets steady and structures safe for generations.
