Engineering design services for the construction of civil engineering works

Tender description

The objective of this project is the identification, design and submission (for planning consent) of a Flood Relief Scheme, that is technically, socially, environmentally and economically acceptable, to alleviate the risk of flooding to the Community of Shannon Town and Environs to a determined standard of protection and to procure, manage and oversee the construction of that Scheme. The consultant shall produce and deliver a set of flood maps that are based on: • a full and detailed hydrological assessment, that has been developed in a manner that addresses the lack of calibration and validation data; • hydraulic conditions that accurately reflect the existing hydraulic arrangements and baseline conditions, including the presence of the existing pumps and flow control structures; and • updated coastal tide, surge and wave data from the Irish Coast Wave and Water Level Study 2018 (ICWWS, 2018). The consultant shall assess, develop and design a Flood Relief Scheme: • that achieves effective protection from the estuary through the upgrade, replacement, realignment and extension of the existing embankments; • that includes the optimisation of the operation of the existing pumps within the smaller catchments and any additional pumping requirements identified, and • that addresses any residual flooding within those smaller catchments following that optimisation of the pumps; and The tasks that are to be carried out to fulfil this objective are described in detail within this tender specification.
