Contractor Porr has said that its deep tunnel storm water system in Dubai is on track to be completed for 2020.
In a joint venture with Belhasa Six Construct, Porr is constructing a 10.4km tunnel that will manage rainwater and groundwater, draining almost 40% of Dubai’s urban area, including the Dubai South, Al Maktoum International Airport, and Expo 2020 Dubai
With intake shafts at depths of up to 45m, the 10m inner diameter tunnel will be excavated by two 11.05 m diameter tunnel boring machines - the largest ever used in the United Arab Emirates.
According to Porr, the two starting shafts have already been excavated and new Austrian tunnelling method (NATM) works have commenced to build the underground starter caverns for the later tunnel boring machine assembly.
Porr CEO Karl-Heinz Strauss said: “Dubai is one of the main hubs for the Arab economies and achieving market entry in the United Arab Emirates is a genuine milestone for Porr.
“Our longstanding experience coupled with cutting-edge projects in terms of pioneering technology and our exceptional international reputation for realising complex, large-scale infrastructure projects were key factors in the award of this contract.”
The factory acceptance tests of the tunnel boring machines has been completed and the machines are expected in mid-October. In the meantime, the JV will start segment production.
The £300M project will take around 36 months and will be ready in the time for Expo 2020 Dubai.
