Impact in the old city, in a space with a difficult topography and marked by the intensity of the different elements which belong to its history.
The aim was to provide a new meaning of a bordering space to warranty the link and accessibility between the old city and the new suburb through a pedestrian footbridge.
Its broken perimeter starts as an extension of the historical wall and it finishes twisting towards a prearranged place. The stairs, a singularity of the project, appears as the interest of giving a sole answer to the accessibility of this space. As such, the structural and geometrical plan is defined with a line in a “Y” shape.
The footbridge design pledges to join together the construction and the structure, where all components involved combine both concepts. Thus it remains deliberately free from superfluous elements, where the chromatic balance between different materials used and its various textures and colors, create a chromatic and material balance with the fortified surroundings, contributing with an uniformity which gives to the volume an uniform identity, nearly sculptural which the constructive simplicity wants to emphasize.
The rest of the project is basically a pavement of big format lime slabs which is geometrically defined by the layout imposed by the footbridge, finishing the accessibility with the rest of the fortified edge.
The approach of the project, in a clear intention, sought a footbridge layout which recognizes its urban condition in this precise location paying special attention to the geometry of this place.
It reflects the refined proportion as one of the parameters of a footbridge.
The project, in line with the search of the formal simplicity had special interest on keeping the contact of the footbridge over the historical layout, as an effect, it is presented as “simply leaning” in a respectful presence.
FORMAL CONCEPT OF THE GUIDELINES SECTION
A. The search of the aligned continuity of the wall
B. The harmonic solution through the geometrical mimesis of the footbridge section and the linen of wall.
C. Materiality as the search of the compromise between the structural efficiency, the chromatic balance and parallel aging with the linen of wall
STRUCTURAL CONCEPT: 'Y' SHAPE VERSUS ALIGNMENT LAYOUT
A. Higher structural stability and better behaviour against horizontal loads.
B. Foundations optimizations
C. The stair creates a “false arc” scheme which make easier to avoid big distances and involve a reduction on the section generating a more efficient solution
