Itajaí-Mirim flood-channel widening and dredging

Santa Catarina Civil Defense; active river dredging in the Itajaí basin as delivery-method context, not the P508221 Itajaí-Mirim works

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 signal

Approval in Brazil

Treat the World Bank project API as an approval and portfolio-status milestone. The state engagement plan defines the river works, and a separate municipal contract is preparing an executive dredging design for a natural-river reach. The records do not identify the main P508221 works contractor, tender value, notice to proceed, final dredged quantity, sediment route or accepted hydraulic performance.

Project anatomy

Scope, counterparties, and execution logic

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 read
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.
Next milestone
An updated procurement plan or state tender that names the Itajaí-Mirim works package, scope split, estimate, qualification route, environmental prerequisites and bid timetable

Material change register

What changed, when, and what it proves

Only source-bound events that alter phase, scope, counterparties, delivery, completion, commissioning, or acceptance are listed. A change can advance the record without proving the next gate.

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.

Read controlling 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.

Read controlling 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.

Decision watchpoints

  • 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

Record control

Evidence reviewed date is not a project-event date.

IMWO changes phase, participants, scope, completion, or acceptance wording only when a dated source establishes the change. The review date records when the evidence set was checked; it does not claim that physical work changed on that date.

Source record

The World Bank project API supplies the Active and Board Approved status, 2 July 2026 approval date, USD 119.2 million current IBRD commitment, borrower, implementing agency and 31 August 2033 financial closing date. The press release supplies the beneficiary count and high-level dredging, embankment and floodgate scope. The older concept PID provides the financing composition and component envelope, so its USD 149.4 million total remains separate from the current commitment. The state PEPI and MGAS define the river reaches and physical interventions. The April procurement plan is the boundary against reporting a main works tender or award. The municipal 4 May article records a separate executive-design contract for a natural-river reach; it is preparation evidence, not construction mobilisation.

Phase: approval. Evidence reviewed: 19 July 2026.
