Contrack Nass installs new Bahrain flyover

Manama, February 1, 2014

Contrack Nass JV has successfully built and installed a new flyover at Mina Salman in Bahrain with the help of subcontractors.

The main contractor at the Waterfront Development Project, Contrack Nass JV installed the US Navy Flyover Bridge using one of the most cutting edge approach.

The company began the work at Prince Khalifa Bin Salman Highway on Thursday night and completed it the next morning. As a result of the work, the highway was closed to traffic.

Contrack Nass JV led the unique bridge construction effort. Its approach was one of the most cutting edge which included: “build, lift, move andinstall” and is unlike any bridge installation undertaken in the Middle East, said a senior official.

“The flyover bridge is approximately 122.5m long, 16m wide and 21.4m tall (from ground 27.5m), and is a tied arch cable suspension bridge with a roadway and pedestrian walkway," stated Ghazi Nass, the supervisory board member of Contrack Nass JV and director of Nass Corporation.

"The 16 m wide bridge deck is a concrete post tensioned construction. The entire bridge was built at an offsite facility 250 m away from the permanent location across Prince Khalifa Bin Salman Highway and was moved to be placed at two end piers with highway completely open,” he added.

Contrack International chief executive Wahid Hakki pointed out that it would remain a landmark project in the history of bridge construction in Middle East.

"We are proud to have lent our experience with accelerated bridge construction techniques to help set a new standard of efficiency for transportation projects in Bahrain," he stated.

“Known as the ‘SPMT (Self-propelled Modular Transporter) Bridge Move’, a team of experts from Contrack Nass J.V. and SarensNass Middle East moved this off-site manufactured bridge weighing 2650 metric tons (with lifting beam 2850 MT) from the assembly location to the highway, said Ayman El Gayar, the regional manager of Contrack International.

"The use of self-propelled modular transporter technology provides the ultimate flexibility and speed in moving and installing bridge structures and reducing construction related impacts to the traveling public as a major priority for the nation's highway program”, he explained.

“Construction on the bridge began in September 2012, and the actual movement of the bridge to the highway started on January 30 night from 12.30pm till Friday at 8.30am”, revealed project manager Ali Chahine.-TradeArabia News Service
