The project included the hydrogeological analysis and the 2D hydraulic model of the valley section in correspondence of the crossing of Ufita river (Campania region, Italy) of the railway viaducts. The analysis considered several return periods, such as T=30, 100 and 300 years and, for the temporary construction phases, T=5 and 15 years.
The output consists in stormwater drainage layouts, large scale layouts for the hydraulic hazard, paying particular attention to the flood risk, of longitudinal stormwater drainage profiles, large scale layouts of catchment areas, layouts of speed and levels.
The hydraulic design includes the hydraulic works on Ufita river in correspondence of viaducts, riverbed works, and protection works.
The four viaducts consist in decks 25, 45 and 65 m long, for an overall length of 2 km. The 25 m decks are in prestressed concrete, and the longer decks for the river crossings are mixed steel-concrete structures.
Hirpinia railway station footprint is 100m x 70 m, is a reinforced concrete structure with an underground floor, a ground floor and a mezzanine level.
The design of the platforms includes a steel shelter for protection of the travelers.
The engineering services include also:
The whole design is developed according to the Building Information Modeling (BIM) using dedicated software and targeted information concepts.
The project consists in the construction of a 9.4 MW Hydroelectric Plant. The plant consists of:
Scope of services
The Alpina mandate includes the preparation of the Basic and Detailed Design for construction of the all the civil and hydromechanical works.
The project consists in the construction of a 8.7 MW cascade Hydroelectric Plant. The plants consist of:
Nakra 1
Nakra 2
Blanco hydroelectric plant is located in Chile, Bio-Bio region, Alto Bio-Bio municipality.
The Blanco plant works with 1 mᶟ/s of flow and it is mainly composed by a weir, a 3,2 km and 700 mm diameter adduction pipe, a penstock, a powerhouse with a one Pelton turbine of 2,4 MW output and a discharge channel.
Alpina developed the entire hydraulic, structural and geotechnical design for the runoff river plant.
The project involves the construction of a building in the European research centre (JRC) located in the municipality of Ispra. The intervention consists of the total demolition of the existing building and its reconstruction through the construction of a main body (depot) with position, orientation and height similar to the current one, and to the South-West, of a lower lateral structure, attached, in which an office with toilets will be added. The new project involves the construction of a total internal volume (upper structure and lower structure) of around 1400 m³, thus a volume similar to the existing one. The parking area and the loading/unloading area in front of the driveway entrance will be covered by a shelter that will be built as a sort of portal that transversely crosses the whole building and is partially on top of it in a longitudinal direction.

On February 10th 6.5 km TBM water supply tunnel has been fully excavated from Bigte to IPO Dam Reservoir in Metro Manila Region area.
A challenging design came to the end of its realization 2 months in advance on the scheduled time!
Happy to have been part of it!
On September 23rd 2019 Federica, the 11.26 m diameter TBM, successfully completed the excavation of the first 9 km section between St-Martin-la-Porte and La Praz, which is part of the 57.5 km Lyon-Turin base tunnel.
Alpina celebrates this important milestone thanks to the competence and skill of her on-site Supervision Team!
Alpina celebrates a long and successful project: after 5 years of hard work, in 2019 Portonovi Montenegro comes to reality: 250.000 sm of top class resort area, 2 km of new coastline, a new 220 berths Marina, luxury residential buildings.
Proud to be the designers of it!
