The engagement, formalized by the construction company Astaldi S.p.A. as a result of participation in the tender for the design and execution, refers to the design of all the objects; in detail, the IRP Biuro Projektów was responsible for the building design and for the details of execution about: - 11 viaducts along track with lengths variable between 16 and 750 m - 8 Overpass with lengths variable between 28 and 148 m - 26 underpasses. The structures have been designed considering different conditions for each object. For the foundation, there were considered directly and indirectly solutions; as retaining works on the back of the structures, it was made use of classical solutions in reinforced concrete and, in some part, the use of the reinforced soil. Even for the decks they were considered different solutions: some decks were designed by providing simple “T” beam, while on some other viaducts it is preferred to use of “V” beams.
