Execution Challenge
All aggregates, skilled workers and equipment had to cross open sea from the mainland.
The islands had no deep-water ports or cargo berths, so materials moved ship to shore in rough surf.
A six-month monsoon shortened the working season, and with no local manufacturing, the team built self-sufficient engineering camps from scratch.
Strategic Role
Mr Avarrsekar led the bid strategy around maritime logistics and set up a central governance office to manage risk across sea channels.
Working with public works committees and tribal councils, he cleared design changes quickly to protect the schedule.
Actions Taken
- Ran a multi-island parallel schedule so superstructure work proceeded concurrently.
- Set up mainland consolidation hubs at the Chennai and Kolkata ports.
- Engineered a landing system using shallow-draft vessels to beach materials directly ashore.
- Built self-sufficient island camps with captive concrete batching and power.
- Used satellite weather monitoring to time open-sea cargo transits.
Outcome
The turnaround delivered 4,334 single-storied permanent shelters completely equipped with independent electrical, water, and sanitary infrastructure, permanently stabilizing local socioeconomic lifelines.
Engineered to withstand Seismic Zone V parameters, the asset establishes a national benchmark for remote post-disaster public infrastructure execution.
For industry leaders, it demonstrates how aligning complex maritime logistics with objective procurement criteria yields highly predictable, resilient assets that safeguard public safety.
Technical Data of Record
Scope of Work
Turnkey construction of 4,334 permanent single-storey shelters with internal water supply, sanitation and electrification across multiple islands.
Key Specifications & Challenges
RCC foundations rated for Seismic Zone V and anti-corrosive materials for marine salinity. Complete isolation with no local materials or labour, open-sea logistics without deep-water berths, and a six-month monsoon.
Major Deliverables
4,334 shelters, plumbing, sanitary assets, electrification grids and self-sufficient island encampments.
Result
Permanent housing restored, with 100% material traceability, satellite weather tracking and health and vector-control measures in labour camps.
