The subject of the contract is the creation of a DNS that will be used for placing orders for the adjustment of the geometric position of the open track superstructure by means of an automatic track tamping machine with a graphical output after the track has been adjusted. The contractor will ensure the adjustment of the position of the track rails of the open track superstructure consisting of grooved rails of type NT1, NT3, Ri 60, as well as head rails of type 49 E1 secured on wooden or concrete sleepers with a gauge of 1000 mm. The work will be carried out on the basis of the technical project documentation and instructions of the purchaser with the submission of an output protocol with a graphical output of the tamping machine before and after tamping, defining the actual position at the specific location of the track being adjusted, while observing the valid regulations for the geometric position of the track with a tolerance of up to 3 mm for the mutual position of the track rail pads. The contractor will ensure, at their own expense, the transport of the equipment to the workplace within the tram network, control and compliance with safety at work. The work will be carried out according to the instructions of the purchaser and during the times of tram service interruptions.
