Dubai tunnel megaproject set to ramp up

August 05, 2018

undefinedWork is set to accelerate on one of the largest infrastructure projects ever built in Dubai.

A joint venture of PORR-Six Construct is currently building the Deep Tunnel Storm Water System for Dubai Municipality.

The duo has formally taken delivery of a pair of giant tunnel boring machines (TBM) in China - the largest ever used in the UAE - to excavate a 10 km long tunnel with a boring diameter of 11.05m.

The machines are expected to arrive in Dubai in October 2018 with work on track for timely completion ahead of Expo 2020, Six Construct parent company BESIX said. 

The tunnel will collect groundwater and storm water runoff from the Dubai World Central area and adjacent communities.

Following detailed and successful tests by PORR specialists on the two TBMs at the manufacturer’s factory in China, on 29 July representatives of the PORR-Six Construct JV signed the “Factory Acceptance Certificates” together with manufacturer China Railway Engineering Equipment Group (CREG).

Christoph Duempelmann of PORR, project director of the Deep Tunnel Storm Water System project and Francois Springuel of Six Construct, Deputy Project Director, took delivery of the machines at a singing ceremony also attended by Zhang Zhiguo, Group Director and Deputy General Manager of CREG.

PORR and Six Construct was awarded the tunnel contract by Dubai Municipality on 1 October 2017 and placed orders for the two machines with CREG the following November. 

The tunnel will serve Dubai’s growing residential and business communities emerging in the south of the emirate and will drain almost 40% of the entire urban area of Dubai, including the flagship project Dubai South, with Al Maktoum International Airport, the Expo 2020 site and several other emerging developments. 

Christoph Duempelmann said: “The PORR-Six Construct Joint Venture and CREG have been working very hard to meet the tight schedule till date. To finalize negotiations for such long-lead key equipment, and then design and manufacture two completely new TBMs of this scale in only nine months is extremely challenging, and was only achieved due to the great commitment of all parties, the joint venture including PORR technical head office team, the TBM manufacturer, the Designer, the Project Management Consultant and Dubai Municipality.”
