BUILDING DAMAGE ASSESSMENT

Project Overview

Consultancy Services for Building Condition survey & damaged assessment of Royal Calcutta Turf club for the Proposed Project premises at 11, RUSSEL STREET, KOLKATA – 700 071.

Scope of Work

Building condition survey of Royal Calcutta Turf Club

• Condition Assessment of the RCTC Heritage Building including its foundation details, distress mapping, estimation of mortar strength, etc., in conjunction with the requirement of the relevant stipulations of conservation of heritage structure.
• Site visit.

Building damage assessment study.

• Study of the details of construction methodology to be adopted, including earthwork retaining system by diaphragm wall/sheet piling/shoring details, etc.
• Prediction of ground movement due to deep excavation and constructional methodology to be adopted, and assessment of risk to the heritage building, including potential damage due to deep excavation, piling, and other constructional disturbances such as vibration propagation, if any.
• Proposal for monitoring scheme for the heritage building during construction, including Tilt, Settlement, Cracks, and other distresses.
• Probability of ground movement due to proposed construction and Structural Impact Assessment of the referred RCTC building of heritage importance, incorporating soil structure interaction analysis (only Plaxis 2D model shall be evaluated).
• Support for vetting from Jadavpur University.

Project duration – 2023 to 2024

SOBHA ALTIUS, SECTOR 106, GURUGRAM

Project Overview

Sobha Limited is planning to construct permanent diaphragm wall for proposed basement excavation at Sector 108, Gurugram. The proposed building will consist of triple basements with maximum excavation below existing ground level up to 13.7m.

• Excavation Depth: 13.7m below ground level.
• D-Wall Thickness: 600mm thick reinforced concrete diaphragm wall.
• Subsurface Conditions: Medium dense sands, non-plastic silts, and clay layers were encountered.
• Groundwater:
  • Groundwater observed at depths of 9.1m to 9.9m in boreholes.
  • Dewatering wells will be installed behind the diaphragm wall during excavation.
  • Temporary groundwater level considered at -9.0m below ground level.
  • Permanent groundwater level considered at -4.0m below ground level.
• Geocon International Pvt. Ltd. was appointed geotechnical consultant by M/s. Heritage Constructions for design of diaphragm wall scheme.

Scope of Work

• Construction stage (temporary conditions) with soil structure interaction.
• Post construction (permanent condition).
• Review of design documentation and drawings.
• Verification of compliance with relevant codes, standards, and regulations.
• Assessment of structural integrity, feasibility, and safety measures.
• Recommendations for design improvements (if necessary).
• Report submission with findings and suggestions.
• Site visit.

Project duration – 2024 to ongoing
