Prague has announced a contract for the construction of a collector under Hlávkův Bridge

Prague - Prague has announced a contract for the construction of a collector beneath the Hlávkův bridge. Its estimated value is 370 million crowns. Prague published the tender in the public procurement bulletin. The collector is meant to connect two other collectors terminating on both banks of the Vltava River. Currently, the engineering networks run through the bridge.
    The new collector is to run across the Štvanice island and beneath the Vltava River, and it is to be completed by March 2016. Its construction will be challenging, as the construction company will have to deal with complicated geotechnical conditions. Prague must build it so that it can begin a major renovation of the Hlávkův bridge itself in the near future. The collector has had construction permission since 2006, which has had to be extended twice.
    The collector network allows for continuous monitoring, maintenance, and replacement of engineering networks, laying new networks, and performing maintenance on technical equipment without any disruption to the street surface.
    The collectors in Prague measure approximately 90 kilometers in total. In corridors that are 2.4 meters high and 2.7 meters wide, all engineering networks such as electrical wiring or water supply are installed. The collectors are managed by the company Kolektory Praha, which is owned by the capital city.
