Metro officials in Beijing are kicking off work on the city’s 27.7km long, US$1.46bn fifth mass transit underground line with an international call for construction tenders for the 16.9km long tunnel section.

The Beijing Mass Transit Railway Group Corporation said it had invited local and international contractors to register for tender documents by mid-August. The corporation, which was created by the Beijing municipal government to finance, design, build and operate the line, said it would shortlist contractors ready to invite tenders and start construction by the end of this year.
