📋 Tender Overview
Scope of Work:
To Develop Dubai Strategic Sewerage Tunnels (DSST) project.
Description:
Under the current plan, the $22bn DSST project is broken down into six packages, which will be tendered as public-private partnership (PPP) packages with concession periods lasting between 25 and 35 years. The first package, J1, comprises Jebel Ali tunnels (North) and terminal pump stations (TPS). The tunnels will extend approximately 42 kilometres, and the links will extend 10km.
The second package, J2, covers the southern section of the Jebel Ali tunnels, which will extend 16km and have a link stretching 46km. W for Warsan, the third package, comprises 16km of tunnels, TPS and 46km of links. J3, the fourth package, comprises 129km of links. J1, J2 and W will be procured under a design-build-finance-operate-maintain model with a concession period of 25-35 years. J3 will be procured under a design-build-finance model with a concession period of 25-35 years. Once completed, Dubai Municipality will operate them, unlike the first three packages, which are envisaged to be operated and maintained by the winning PPP contractors.
J1, J2, W and J3 will comprise the deep sewerage tunnels, links and TPS (TLT) components of the overall project. For each EPC contractor, the technical prequalification may be in respect of one or more components - which include deep sewer tunnels, terminal pumping stations and/or link sewers, as applicable - of one or more DSST-TLT Packages. Dubai Municipality has appointed Abu Dhabi-headquartered Tribe Infrastructure Group as lead and financial adviser, UK-based Ashurst as legal adviser and US-based Parsons as technical adviser for the DSST project.
