Saudi Arabia, which is trying to curb domestic fuel consumption, said it shortlisted four groups to submit bids to build the first electrical subway train network linking major areas of its capital city, Riyadh.

The four groups should present their financial and technical bids for the project within four months, the Saudi Press Agency said today, citing Prince Sattam bin Abdulaziz, the head of ArRiyadh Development Authority.

The first group, led by France’s Vinci SA (DG), includes Siemens AG (SIE) and Saudi Arabia’s Almabani General Contractors Co., the state-owned news agency said. The second is headed by Canada’s Bombardier Inc. (BBD/B) and includes Saudi Arabia’s Al Rajhi Holding Group and South Korea’s GS Engineering & Construction Corp. (006360) The third group includes Samsung C&T Corp. (000830), while the fourth is led by Strabag SE (STR), central Europe’s biggest construction company.

The winner of the tender will build an underground network, provide electric trains, construct bridges and subway tunnels and provide all the engineering and design for the project, the news agency said.

The 175-kilometer (109-mile) electrical rail link will connect Riyadh’s airport with other parts of the city, including the new King Abdullah Financial Center, according to the authority’s website.

City planners are also reviewing requests by 16 groups interested in bidding for a public transportation network project that involves operating buses and building bus stations and parking spaces. The planners will soon select the initial qualified bidders to submit their bids, SPA said.
