AIL tunnel, Agno

Cunicolo AIL Agno-Bioggio

The AIL Agno-Bioggio tunnel for high voltage systems runs alongside the Vedeggio river for 4 km and, in a central stretch, is also bordered by the Prati Maggiori canal. Precisely at this point the route of the structure crosses the Riale Roncaccio drainage canal.

To overcome it, the tunnel dives further below the riverbed up to -5 meters from the ground level. Due to the particularly delicate position exposed to multiple water pressures, this section of the tunnel was created with a total Drytech Tank: foundation, walls and slab.

The Drytech Tank structure of the AIL Agno-Bioggio tunnel has a thickness between 30 and 40 cm and the joints have been waterproofed with injections of DRYflex expanding resin.

By sealing the entire thickness of the joint, the resin also protects the reinforcing bars, because it keeps water completely outside the concrete. In the event of any infiltrations, the system provides practical and easily manageable maintenance from inside the structure, without interruptions to the service.

The real possibility of carrying out maintenance contributes to the main quality of waterproofing: which is to prevent water from entering for the entire life of the work, i.e. for 50 – 100 years in the case of civil engineering structures, as prescribed by SIA 272.

CPC Gym, Chiasso

The CPC double gym in Chiasso is the victory of lightness over weight, interaction over separation, flexibility over rigidity.

The duality between the podium and the covering volume of the room is defined by a detachment, produced by a punctual support on all four sides.

Through this suspension, the monolithic volume appears very light, to the point of seeming to be held back – rather than supported – by the four lateral Vs.

The detachment connects the interior space with the urban and natural elements that surround the gym. An interaction that places it in the context of the school and cultural campus, weaving various relationships with the peculiar elements of the place.

The building reacts to different situations and topographical differences. To the north it has an access terrace, in relation to the school buildings and access from the public car park. To the south, a flight of steps in relation to the small garden.

A delimitation of the road field and the existing square to the east. Finally, it is at the same level as the m.a.x Museum and the Spazio Officina, sharing their public vocation.

The podium is a Drytech tank. The insulation of the internal facades is protected by an exposed wooden strip in the lower part and by an acoustic paneling in the upper part.

From an energy point of view, the building meets the criteria of the Minergie standard.

AlpTransit Control Center, Pollegio

AlpTransit Polleggio Operation Center

The AlpTransit Polleggio Operation Center manages the railway traffic of the Gotthard and Monte Ceneri base tunnels.

Known as “The Periscope” for its futuristic architecture, the POC is one of the four SBB operating centers in Switzerland, together with the ultra-modern centers of Lausanne, Olten, Zurich.

Height and shape of the building are the architectural response to two functional constraints.

The POC marks and declares the entrance to the Gotthard base tunnel. It is a symbol.

To be perceived as such by the railway and the motorway it was developed in height.

The second constraint is the dimensional incompatibility between the control room and the type of an office building, which has led to accepting the contrast and expressing it in a radical way. Thus, the double-height slab of the control room is grafted onto a trunk of office space, arranged diagonally on the lot.

The AlpTransit Polleggio Operation Center therefore appears as a sculptural object animated by a twist between the two volumes.

Seen from a moving vehicle it transforms, changing its proportions and offering different states of balance.

Sant’Anna Hospital, Como

The new Sant’Anna hospital in Como is located on an area of ​​over 80,000 m² south of the city of Como and a few hundred meters from the headquarters of Drytech Italia.

The Como Polyclinic has two underground floors exposed to a 2-meter flap, which will also house the operating theaters.

The waterproofing was carried out with the Drytech Tank System which, among other things, due to its construction characteristics and organization, ensured a significant reduction in days in the overall construction site budget.

The activities of the Drytech Tank System, in fact, are parallel to the others of the construction site so that, in fact, the waterproofing item has been removed from the work calendar.

To support the weight of the structure, the site of the construction site was consolidated with approximately 4000 reinforced concrete poles, with a depth varying between 20 and 30 meters.

The poles were thrown into shirts driven into the ground with micro-explosions.

Borgo alla Marina, Genoa

The conversion of the industrial port area, west of the Genoa airport, also involves the construction of the Borgo alla Marina residential complex.

200 prestigious apartments, with relative berths and garage, overlooking a new tourist port.

Under the buildings and the square, in direct contact with the sea water, the covered parking for residents is built with the Drytech Tank System.

City by the Sea, Savona

Excellent news for the sky arrives from the sea.

The residential center La Città sul Mare in Savona, in fact, heats up in winter and cools down in summer by exploiting the sea temperature.

The plant is zero-emission and, using a renewable and free resource, provides a definitive solution to the problems of atmospheric pollution and the soaring costs of fossil energy sources.

The Savonate housing complex was built by Meraviglia Spa of Bulgarogrosso (CO) and was designed by the Technion Srl and Ellevi di Lecco design studios.

The 120 apartments are served by a heating system connected to a sea outlet, built on the boulder pier facing the complex.

The basic principle of the system is the substantially constant temperature of the sea water (about 18 ° in this stretch of coast).

The pipes of the heating and air conditioning system from the building run underground to the sea intake, where the heat pump is located, which uses sea water as a source or as a heat sink.

The transport of thermal energy takes place through the same water. Water that is sucked from the sea, brought up to the heat exchanger and, therefore, released.

The system has a positive energy balance: it supplies more energy (heat) than electricity needed for its operation (the ratio is at least 1 to 4 or higher, up to 1 to 6).

In addition to the seawater intake, the two floors of the Città del Mare underground car park are also made with the Drytech Tank Waterproofing System, which is exposed to a 5-meter water table, as can be seen from the pressure of the jet that comes out of the pump well in the third image.
