The Via Capitolina residential complex consists of three independent buildings providing 40 housing units, constructed on the slope of the San Giusto hill.
The residences include two parking areas for a total of 50 car spaces, both in enclosed garages and open-air parking bays, developed on multiple levels beneath two of the buildings and directly connected to their respective structures.
The main challenge addressed in the project was related to the foundation system requirements in relation to the support of the downhill slope and the adjacent buildings. The soil conditions, characterised by a landslide-prone configuration, required the construction of diaphragm walls with a soldier-pile system, reinforced concrete piles combined with steel profiles (HEA and HEB sections 140–160 mm), properly anchored with triple-strand steel tie rods, grouted with cement slurry and post-tensioned using steel plates and trusses.
The above-ground structures of the garages, which interact with the hillside, were built using reinforced concrete shear walls designed to resist lateral earth pressure, while the residential buildings were constructed with a reinforced concrete frame system.
Once the structural phase was completed, the entire structure was clad with infill masonry and concrete diaphragm wall finishes.
