2x660 MW Supercritical Thermal Power Plant, NTPC, Selda, Madhya Pradesh

Overview:
Cengrs Geotechnica Pvt. Ltd. conducted a geotechnical investigation for the proposed 2x660 MW coal-based supercritical thermal power plant near Selda, Madhya Pradesh. The study aimed to evaluate subsurface conditions and provide reliable foundation design recommendations.
 

Client and Project Details:
Client: Larsen & Toubro Limited (EPC Contractor for NTPC)
Project Site: Selda, Khargaon, Madhya Pradesh
Purpose: Foundation design for thermal power plant facilities
Completion Date: October 12, 2015

Key Findings:
Stratigraphy:

• Layers of sandy silt and clayey silt with intermittent weathered rock strata.
• Rock is found at varying depths, with good rock quality in certain areas.

Groundwater: 

• Encountered at 10–15 m below ground level.
   

Foundation Recommendations:

• Open foundations for lighter loads on rock layers.
• Pile foundations for heavier structures requiring higher load-bearing capacities.

Technical Highlights:

Field Investigations:

• Drilled 116 boreholes up to 30 meters.
• Conducted pressuremeter and plate load tests for in-situ soil strength.
• Performed cross-hole seismic and resistivity tests for dynamic soil analysis.

Laboratory Analysis:

• Evaluated soil compaction and bearing capacity through standard proctor tests.
• Chemical analysis of soil and water for durability assessment of foundations.

Client Impact:

The detailed geotechnical report enabled Larsen & Toubro to implement safe and cost-effective foundation systems, ensuring timely execution and structural stability of the thermal power plant.

Conclusion:
Cengrs Geotechnica’s expertise and comprehensive investigation facilitated a reliable and sustainable foundation design for NTPC’s supercritical power plant.
