World Bank project is Active and Board Approved; the April 2026 procurement plan omits the Itajaí-Mirim main works package

Project sources

Santa Catarina's flood-resilience programme includes widening and deepening the rectified Itajaí-Mirim channel, desilting part of the old river and installing two flood-control gates. The World Bank records the USD 119.2 million project as Active and Board Approved; its April 2026 procurement plan omits the main river works package.

Project anatomy

Contract scope and delivery roles

Client / authority
State of Santa Catarina, through the Secretariat for Civil Defense and Protection
Delivery parties
Main works contractor not identified; public construction procurement remains pending
Contract route
World Bank investment-project financing under P508221. The project API records a USD 119.2 million current IBRD commitment and Board Approved status. The December 2024 concept record set out USD 149.4 million in total financing, including USD 119.2 million from IBRD, USD 29.8 million in state counterpart funding and USD 0.4 million from GFDRR. The April 2026 procurement plan lists a regional monitoring consultancy but no Itajaí-Mirim main works activity.
Execution window
The World Bank project API gives a financial closing date of 31 August 2033; this is not a construction completion date. No public main-works tender, award, notice to proceed or completion date was identified at the 19 July 2026 cutoff. Itajaí municipality separately announced a 90-day technical-services contract in May for field surveys, sediment sampling, laboratory analysis and executive design for dredging a natural-river reach; that design contract is not the P508221 construction package.
Works package
Widening and deepening of the rectified channel from the KM 12 area to its mouth at the Itajaí-Açu, desilting part of the old Itajaí-Mirim between Itaipava and the confluence with the rectified channel, two flood-control gates, embankment reinforcement and associated environmental, social, hydraulic and monitoring measures
Marine interfaces
The Itajaí-Mirim works sit in a tidally influenced urban river system connected to the Itajaí-Açu estuary and the Port of Itajaí economy. The public programme is for flood conveyance and control, not port-access deepening. Channel geometry, sediment classification, material handling, bank stability, gate hydraulics, existing bridges and utilities, flood-stage operating rules and environmental licensing remain the core delivery interfaces.
Commercial evidence boundary
The opportunity is upstream of a construction award. The public record defines a substantial river-improvement scope and approved financing envelope while leaving the package boundaries, procurement method, engineer's estimate, bidder field, construction plant, disposal or reuse route, accepted design surface and gate-supply split unpublished. Suppliers should watch the updated STEP plan and state tender portals rather than infer a live works contract from project approval.

Open this project in the Change Log

The World Bank project reached Board Approved status

The portfolio record confirms Active status and a USD 119.2 million current IBRD commitment. The related release ties that milestone to Itajaí-Mirim channel dredging, embankment reinforcement and floodgates without announcing the main works procurement.

Source

Itajaí commissioned a separate executive dredging design

The municipal contract covers surveys, sampling, laboratory work and design for a natural-river reach. It advances preparation but is not the P508221 main works contract.

Source

The first public procurement plan omitted the river works package

The plan listed one monitoring consultancy and did not identify an Itajaí-Mirim works tender, contractor or mobilisation date.

Evidence gap

What remains unverified

Outstanding evidence

  • Updated World Bank STEP procurement plan
  • Main works package split and engineer's estimate
  • Environmental licence and final hydraulic design
  • Pre-dredge bathymetry and sediment classification
  • Dredged-material handling, transport and receiving route
  • Rectified-channel widening and bank-stability method
  • Two flood-control gate supply and civil interfaces
  • Bridge, utility and urban-access constraints
  • Notice to proceed, mobilisation and measured production
  • Post-work survey, gate testing and flood-system acceptance
