Technical Support Services for the Joynton Ave Stormwater Drainage Upgrade

⁠⁠⁠The Council of the City of Sydney ("Council") invites tenders for the provision of Technical Support Services for the Joynton Avenue Stormwater Drainage Upgrade Contract, in accordance with this request.

The Joynton Avenue Stormwater Drainage Upgrade contract involves the detailed design and construction of stormwater lines to reduce flooding in the Green Square Urban Renewal area. In summary, the Works consist of constructing approximately 750 lineal metres of 1.8 m diameter reinforced concrete pipe, as well as shorter lengths of reinforced concrete box culverts, smaller diameter pipes, manholes and junction pits, a new Gross Pollutant Trap (GPT), connection into existing services and decommissioning of redundant pipework. The stormwater trunk drain is proposed to be installed at depths of up to 4 metres from the surface level to the top of pipe using a Tunnel Bore Machine. It will link the O'Dea Avenue trunk mains in the North with the EX-5 pit of the Green Square Stormwater Drain (GSSD) in the South which was recently delivered by the DG Alliance and located adjacent to the Gunyama Park Aquatic Centre and Ausgrid Driveway (130 Joynton Avenue, Zetland).

The purpose of this proposed engagement is to provide Council with appropriate technical support for the duration of the Project. Council has engaged other specialist consultants, with the intention that the successful consultant will at times liaise and coordinate with other specialist consultants.

Further information on the Scope of this technical engagement, along with information on the scope of other consultants engaged by Council and the main Design and Construct (D&C) contract, can be found in Part B of this Request for Tender.
Tenderers must submit tenders in the manner required by this Request for Tender.
