A programmatic symbiosis: bridge + multi-storey carpark in only one sustainable building
A bridge as a sustainable multi-storey carpark. It is concerned to design the bridge-parking as a symbol of a new utopian architecture as an element-pragmatic for the creation of perfect places from the point of view of economic, social and environmental encouraging a sustainable tourist hedonism. The solution thus opts for a programmatic and pragmatic symbiosis . Rather than erect a discounted bridge next to a very expensive and not sustainable, both environmentally and financially, multistorey car park hidden in the side of the mountain , it was proposed to build a multi-storey car park bridge on two supports: bridge + car park in only one building. In fact, in the area identified by the notice, due to the shape of the site to position the cubage useful to parking, would be necessary large excavation works of this part of the mound and the realization of extended containment works of the lands to prevent landslides . The road bridge is necessary to connect the two neighborhoods of Moena that are located on each sides of the river, and this alternative and innovative proposal linked those two areas while finding space for a large carpark. The proposal sought to avoid any excavation or other work that would have a strong negative impact on the surrounding natural land unless it was absolutely necessary. The architects aimed to keep the green space “free” from buildings, aiming to promote open-air activities and creating a pedestrian and cycling lane. The plan calls for a green-roofed bridge with a parking lot inside and above it. The initial bridge, mandated in the competition brief, was widened to about 36 metres, roughly half of which comprises a roadway, and the other half home to a roof garden that offers views of the touristic village and the mountains to the north. Salamone and Di Bari’s proposal calls for a new public park which can be reached by people coming from the carpark, and offers general access for pedestrian and bikes through a system of ramps that includes the park facilities. It also calls for a bike sharing station that can be used by tourists and local residents, who can leave their car in the carpark and continue their visit by bike. In the main pedestrian entrance to the parking area there is a resting spot and an information point. There is also a bar facing towards mountains and valley, offering amazing views of the surrounding landscape. The multi-storey carpark bridge is characterized by high functionality and by ability to achieve a original building and modern interior bright and welcoming spaces , facades that blend harmoniously with the surrounding environment while avoiding all the works of excavation and containment that would damage irremediably the ecosystem of the context . The construction system is very economic because it consists of prefabricated elements. While the new bridge blends harmoniously with the surroundings, the interior space was designed to maximise the number of parking spaces available. The main load-bearing structure was designed around the perimeter on the north and south sides of the building. This allows for the absence of pillars between the cars, making the parking lot safer and more comfortable for drivers. The construction of the bridge requires steel beams arranged 2.5 metres apart, which support a series of prefabricated elements each measuring 16 metres long by 2.5 metres wide. Inside the building, half of the area on each level has sloping floors, which serve as a vertical connection between levels. An elevator and an open staircase connect the three levels with the open areas on the green roof. The large cover at the top of the bridge, intended to traffic for parking of cars, for bikes and for pedestrians, would offer unprecedented spectacular views , a kind of double-sided viewpoint: the country on the south the peaks to the north.
On the large roof garden, the new lookout, that can be reached also directly from within the carpark itself, is placed a tourist information point with bike sharing service so that it can be used by tourists who leave the car and go on a visit to the locality on a bike.
While the carpark is hidden under the bridge, the green area on the bank of the river so undeveloped for building like was envisaged in the notice, it becomes a park and crossed by bike paths and pedestrian area of transit to Moena. The soil extracted from the bridge’s construction site can be used to model ramps which conform to the natural slope of the land. This creates a small natural amphitheater to be used as an open-air cinema, a place for community events and cultural activities, a theatre, and in winter as the site for an ice skating rink in winter, Christmas markets and children’s playgrounds.
