15/086 - Ringsend Wastewater Treatment Plant Upgrade Project – Capacity Upgrade

The contract consists of the provision of a biological secondary treatment process (the Works) that will result in the expansion of the existing Ringsend Wastewater Treatment Works by a Population Equivalent of 400,000. The Works are located within the existing operational Ringsend WWTP and will involve substantial interfaces with the existing facilities and the incumbent WWTP operator. The incumbent WWTP operator will be responsible for undertaking some works at the interface points. The outline design (including layout and general arrangement of facilities) for the Works has been produced by the Contracting Entity’s design consultants. This anticipates an aerobic granular sludge biological treatment process and the Contracting Entity has procured the proprietary Nereda® process for this purpose. It is noted that some of the Nereda® specific equipment may be procured through a nominated subcontractor. The Works are to be constructed in a relatively restricted area of 0.8ha, within the existing operational facility, and the successful tenderer will be required to: • assume design responsibility for the Contracting Entity’s solution (with the exception of the biological process), • complete the design (again, with the exception of the biological process), and • construct and commission the Works. • undertake the roles of Project Supervisor Design Process (PSDP) and Project Supervisor Construction Stage (PSCS) It is anticipated that the successful tenderer will also be required to assume responsibility for the operation and maintenance of the Works (Capacity Upgrade) after the issuing of the commissioning certificate for a minimum period of 6 months. The Contracting Entity also reserves the right to extend this operation period for up to an additional 3.5 years.
