NW-1 West Bengal Lot A: five concrete floating jetties

Completed modular concrete pontoon and blue HDPE floating walkway at an earlier IWAI West Bengal installation

Contract record 1882585 identifies West Coast Marine Yacht Services Private Limited as the supplier for Lot A of IWAI package IN-IWAI-490109-GO-RFB at USD 2,158,478.24. The official tender allocates five National Waterway-1 locations to this lot: Ghoramara, Nischintapur, Nainan and Katakhali in South 24 Parganas, plus Basudevpur in Howrah. Each site is specified with a 24 m by 5 m concrete pontoon assembled from four units and a 9 m by 2 m HDPE floating walkway.

Project anatomy

Contract scope and delivery roles

Client / authority
Inland Waterways Authority of India under the Ministry of Ports, Shipping and Waterways
Delivery parties
West Coast Marine Yacht Services Private Limited - signed Lot A supplier and installation contractor, Concrete fabrication yard, naval architect, anchorage and mooring supplier, HDPE walkway supplier, verifier, transporter and installation subcontractors - not identified in the reviewed public records, Ronautica and Seaflex - referenced by West Coast Marine as general capabilities or partners, not evidenced as parties to this contract
Contract route
IWAI issued an open national, prior-review Request for Bids on 16 July 2025 using a single-stage two-envelope process. Bidders could compete for Lot A, Lot B or both. World Bank data records Lot A as signed on 18 March 2026 with West Coast Marine Yacht Services; the reviewed award data does not establish a Lot B contractor.
Execution window
The tender requires handover of the goods within six months of contract signing, followed by 24 months of general upkeep and maintenance. If unchanged, that points to a tender-derived handover milestone around 18 September 2026 and upkeep into September 2028. The procurement plan carries a 20 April 2028 contract-completion date. Neither source proves the current production schedule, installation sequence or actual progress.
Works package
Lot A covers Ghoramara, Nischintapur, Nainan, Katakhali and Basudevpur. At each site the schedule specifies one 24 m by 5 m concrete pontoon formed from four 12 m by 2.5 m units, a 9 m by 2 m by 0.8 m HDPE-floater walkway with handrails, adequate anchorage, mooring arrangements, berthing fenders, five lifebuoys, ten life jackets, one portable dry-powder extinguisher and four solar lamp posts. The supplier must provide inspection or certification by IRS, IIT, NIT or a classification society, personnel training, operating procedures, registration, testing and commissioning, followed by two years of upkeep.
Marine interfaces
The five riverbank sites require transport and assembly of modular concrete pontoons, HDPE shore connections, site-specific anchorage and mooring, fendering, safe passenger access and commissioning under changing water levels and currents. Tender language establishes the functional requirements but does not disclose bathymetry, geotechnical conditions, accepted anchor design, tow or road route, lifting spread, installation vessels, shoreline works or location sequence.
Commercial evidence boundary
The World Bank committed supplier amount is USD 2,158,478.24 for Lot A. The procurement plan's USD 5,058,317 estimate covers both lots and is therefore not a like-for-like current contract value. Published evidence reviewed does not identify variations, certified payments, final quantities, retention, subcontract values or the commercial position of Lot B.
