The work supports the environmental authorisation application and covers an updated functional diagnosis, hydrology and ecological flows, salinity and mangrove conditions, hydraulic modelling, and three feasibility-stage management and design scenarios. It also includes residual-impact analysis, avoidance and mitigation measures, compensation and monitoring principles. Applicants must show environmental and hydraulic study experience, relevant references, staff and technical resources, and submit through an electronic catalogue. The award criteria weight technical quality at 40%, price at 30%, assigned personnel at 20% and environmental performance at 10%.
