Client Italferr S.p.A.

Engineering services for the technical-economic feasibility design of lots 1A Battipaglia-Romagnano (34 km), 1B Romagnano-Buonabitacolo (49 km), and 1C Buonabitacolo-Praia (45 km). E.D.IN. developed the design of the railway viaducts for a total of 30 structures with an overall extension of over 30 km and a total of 780 single and double track spans. The activities carried out included the study of viaduct layouts in relation to hydraulic and road interferences and the morphology of the territory, the sizing of typical substructures, deep foundations on piles and shafts and typical temporary works. The project envisages a number of different structural types, starting with conventional filler beam decks with spans of about 20 m and precast pre-stressed concrete girders with spans of 25 m. Within the project, in the presence of widespread interferences and flood areas, composite steel-concrete decks were also consistently adopted with spans of 40 m and 45 m with 4 I-beams and spans from 50 m to 75 m with box girders. Additionally, steel trusses are adopted for single track spans between 60 m and 75m and, finally, special structures, such as steel tied arch bridges with spans up to 120m, are planned for the crossings of the A2 “Mediterranean” Motorway, providing landmark elements characterizing the entire project.

Veneto, northern Italy, 2022-2023

Client IRICAV 2 Consortium

In the framework of the design of the high speed railway line Verona – Padova, lot 1 (1st and 2nd sub-lots Verona – Montebello Vicentino and Montebello Vicentino – Bivio Vicenza) E.D.In has developed the Detailed Design of 12 viaducts for an overall extension of about 7000m. Main structures of the project include viaducts on the Fibbio and Alpone rivers, of 2380 and 1770m long respective lenghts.  The decks are of prestressed concrete for spans of 25m, composite steel-concrete for spans from 40 to 46m and filler beams with spans up to 22m. The piers are box shaped with rounded edges, while abutments have a standard geometry. All foundations stand on large diameter piles.

Iraq, 2022 – in progress

Client BTP Inc.

The “Development Road” project consists in the new Railway & Highway Systems (i.e. a multimodal corridor of almost 1,200 km in length), aimed to connect the new Grand Faw Port up to the Turkish Border and enhance the socio-economic development of Iraq. The new Railway system shall be designed in order to transport passengers at 300 km/h and freights at 120 km/h, while serving most of the Iraqi cities from South to North. Main structures of the railway include typical spans of 25m in prestressed concrete, composite steel-concrete decks for 40m and 50m spans as well as steel trusses for 70m spans. Special structures within the Project include a steel tied arch bridge with a 100m span and a cable stayed bridge with a total length of 400m and a main span of 200m. Within the project, E.D.IN. has developed the Feasibility Study and Preliminary Design of all the Railway and Highway bridges and viaducts as well as minor structures such as overpasses and underpasses.
