Rebuilding Mantralaya while Maharashtra Kept Working

Share this Case Study:

Project Context

Fire-damaged reinforced concrete had to be strengthened without vibration while the floors below stayed in daily use. The site was congested and high-security, with deliveries possible only at night. Civil, MEP and interior work, coordinated across public works, independent architects and statutory bodies, had to fit within twelve months.

Execution Challenge

Fire-damaged reinforced concrete had to be strengthened without vibration while the floors below stayed in daily use. The site was congested and high-security, with deliveries possible only at night. Civil, MEP and interior work, coordinated across public works, independent architects and statutory bodies, had to fit within twelve months.

Strategic Role

Mr Avarrsekar led the organization's response to the mandate, from bid strategy to delivery governance.

He set up a risk and accountability structure that turned the inputs of many departments into clear milestones.

He also directed resource positioning so that specialized materials and skilled crews were in place when the schedule required them.

Actions Taken

- Driven civil, MEP, and fit-out in parallel under one integrated schedule.

- Retrofitted damaged structure with CFRP wrapping, micro-concreting and polymer-modified mortar, verified by non-destructive testing.

- Kept the PWD, chief architect and independent consultants aligned through a tiered communication structure.

- Monitored the supply chain continuously to secure specialized materials inside a high-security zone.

- Applied zero-accident safety protocols suited to an occupied public building.

Outcome

The fast-track intervention successfully restored structural stability and modernized three critical floors, delivering institutional-grade offices with upgraded life safety systems. The project validated the firm’s rapid mobilization capacity and execution precision under intense public observation.

For infrastructure leaders, this turnaround demonstrates how aligning sophisticated technical solutions with rigorous public evaluation criteria ensures predictable delivery, mitigates regulatory risks, and secures a definitive competitive advantage in major government tenders.

Technical Data of Record

Scope of Work

Structural rehabilitation, retrofitting, civil works, MEP (HVAC, fire-fighting, IBMS) and interior fit-out across 1.25 lakh sq ft on three floors.

Key Specifications & Challenges

CFRP wrapping, micro-concreting, polymer-modified mortar and an intelligent building management system. Restoring fire-damaged concrete without induced vibration, inside a live, high-security building with night-only logistics.

Major Deliverables

Fully operational ministerial secretariats, modernized Chief Minister's executive suite, advanced disaster-resilient document storage, and centralized energy-efficient HVAC infrastructure.

Safety/Quality Measures

Zero-incident health & safety mandate; multi-layered physical containment and negative-pressure dust screening; real-time structural deflection instrumentation; 100% third-party quality certification for all civil and MEP materials.

Result

Restored, fire-safe floors delivered under a zero-incident safety mandate, with real-time deflection monitoring and 100% third-party certification of civil and MEP materials.
