Rīga Šķirotava Marshaling hump reconstruction

Construction supervision and Contract management

SJSC Latvijas dzelzceļš
Station Šķirotava, Rīga

Šķirotava marshalling yard is the main marshalling yard of Latvian railways. The classification yard consists of 26 tracks, which are comprised of three sets of tracks for splitting-up, formation and preselection of wagons.

Design period - technical assistance

The modernisation of the Šķirotava marshalling yard will increase the capacity of the hump and of the whole Riga railway network ensuring the handling of increasing wagon traffic. This project is a part of a global improvement plan of the East-West Railway Corridor which is the main Latvian freight corridor, giving access from Russia and other continental countries to Latvian ports on the Baltic Sea.

The local contractor BMGS and his subcontractor SIEMENS won a design-and-build contract to modernize the marshalling yard. Siemens will deliver the retarders and hump control system MSR32. Witteveen+Bos Latvia was hired by Latvian railways to provide technical assistance for their engineer to assure FIDIC Yellow Book engineer’s services during the design phase. The design phase was finished in summer 2013 and the contractor has started construction works.

Construction phase – contract management and construction supervision

By winning the open tender, Witteveen+Bos Latvia has become the FIDIC Yellow Book’s engineer and provides management and supervision services during the design phase. The project includes the reconstruction of the tracks in the marshalling yard and shunting equipment, such as switches, point machines and retarders. The hump top will be reconstructed, as well as the telecommunication and power supply systems. The existing yard control system MRC will be connected with the new system from Siemens MSR32. In addition, noise reduction measures are foreseen. Witteveen+Bos Latvia will supervise the construction in all fields mentioned above.

The project is due to be finished in September 2017.
