Germany - Construction of streetcar stops

Description

The Krefeld Hauptbahnhof light rail and streetcar station in Krefeld is being expanded to make it barrier-free.As a result of the arrangement of a central platform and two side platforms, extensive road construction work is to be carried out in addition to structural work and track construction work, including sewer and cable civil engineering work.
At the Krefeld Hauptbahnhof stop, two new low-floor side platforms are to be built for SWK MOBIL GmbH and one high-floor platform in the middle position for Rheinbahn AG.The high-floor platform consists of a 60 m long platform and a 16 m long ramp, as well as an access staircase.The width of the elevated platform is 6.00 m.The elevated platform will be made of prefabricated reinforced concrete elements, each 2.50 m long, for which a construction plan is to be drawn up.The space between the edges of the stop will be filled with suitable soil material.The foundation will be made on an in-situ concrete foundation, as well as a layer of lean concrete. The platform elements are to be electrically interconnected. This is to be planned and executed by a specialist company.Paving work and sealing work is to be carried out on the elevated platform and the ramp.The two low-floor stops are to be constructed using paving with a platform edge made of L-stones and cover plate.Locksmith work for stainless steel knee railings, splash guards and light rail pylons is also to be carried out for the stops.In the low-floor stop, tree beds with walk-over tree pits are to be created.Large parts of the platform equipment are to be supplied and installed.For the work, the affected section of track will be closed and the overhead line system dismantled.Accompanying extensive track construction measures are to be carried out for the construction of the stop system. In the adjacent junction, a complex track intersection with three crossings and five points is to be constructed. The existing track system must be completely dismantled. In the adjacent areas, fundamental renewal measures are to be carried out for SWK MOBIL GmbH. The superstructure consists in most areas of an asphalt covering in the Dresden superstructure. In the renewals also from ballast track. It must be taken into account that sections are used by standard-gauge vehicles of Rheinbahn AG as well as by meter-gauge vehicles of SMK MOBIL GmbH. A four-rail track is to be laid here. The use of a two-way tamping machine is to be taken into account.Elastic rail bedding is to be used in sections.The track construction material is to be provided by the AG.In the area of the ballast track, a track covering is to be supplied as a system solution and installed ready for operation.In the subgrade, drainage lines and cable conduit routes including the structures are to be laid. Both the drainage of the stops, the traffic areas and the track system are to be connected to a main sewer approximately 4 meters deep.An existing shaft structure of the main sewer is to be demolished and constructed outside the track zone with connection supports.For the traffic signal system and operating technology, mast foundations are also to be constructed and connected to the line routes.In the entire construction area, road coverings and side spaces are to be constructed with tactile guidance systems.The entire measure is to be accompanied by surveying. The total measure VE 1 will be divided into four construction areas in accordance with the cost unit allocation, and invoicing will be carried out accordingly. It can be assumed that only a few storage areas will be available in the construction site area, so the Contractor will have to provide appropriate transport logistics and additional storage areas.
