Extending Prague’s metro line

The west end of Prague’s metro line ‘A’ is being extended in a construction project estimated to cost CZK 21.13 billion (expected total capital cost including indexing). The section known as Metro Line V.A is located in the northwest of Prague and will run from Dejvická Station via four new stations: Červený Vrch (Bořislavka), Veleslavín, Petřiny and Motol. After several appeals against the building of the section were addressed, construction began in January 2010. Operation of the new section is expected to start in late-2014.

However, the project’s capital cost had to be reduced and so the general designer was asked to submit cost-cutting measures which were mainly applied to the construction of Petřiny Station.

For the first time in Prague’s metro system, single-track tunnels have been bored using Tunnel Boring Machine (TBM) technology and benefiting from the latest tunnelling machines. Station tunnels and two-track running tunnels are being built using the New Austrian Tunnelling Method (NATM) using access tunnels to transport all material.

The project also includes construction of three bus terminals for urban lines, and zoning and construction permit applications have been submitted for a Park & Ride facility to meet the aim of terminating surface transport further from the city centre.
