OBJETIVO

The circular sink is part of Martner’s original project (tangent to the current runway), now it is rounded by the 80 meters circular ramp highlighting it and also resoling/solving the difference in level in a bounded area. This three-dimensional figure results in a spiral path with a 360° moving view of nearby trees, the city, Cerro Manquehue and the Andes Mountains.
The second section advances 80 meters in a straight line towards the west -on a slope that protects from the noise and vertigo of urban highway. -, extending the route to bring the arrival closer to the school located at that end of the park. The ramp is conceived as a background –in its straight section- and a shadow –in its curved section- enabling a central esplanade associated with the Brasilia square, adjoining and included in the development plan of the municipal public spaces system.
Construction, Modulation, Disassembly, and Assembly.
The torsion of the ascending spiral is resolved in a concentric digital model formed by radial ribs and a central beam, understood as a set of solidary elements. This model unfolds into flat figures of the different pieces, which are cut with CNC on large format sheets of 3000x9000 mm. In turn, these elements - which include semi-cuts for welded joints - are rolled for curvatures and assembled in the factory in nine equal modules plus three adjustment modules for the ends. Then, these prefabricated components are mounted on the in-situ pillars.

CONTEXTO

Rampa Cuauhtémoc. It is an open competition to solve the universal accessibility of a route that continues a system of public parks.
Around an existing Carlos Martner’s original 70’s landscape project, this work solves a bounded intervention over the diverse speeds in the public space: the urban highway, the relaxed walk through a park and the daily crossing of neighbors on the border of two communes. Formerly, the road and the linear park are opposed - forming a cross plan - by a height pedestrian bridge, of intensive use.
Gowth of the avenue has compressed the original pedestrian descent and brought cars close to the park, increased risks and traffic noise.
It is required to climb 6 meters with a constant slope of 5%, which necessitates 120 meters long ramp. Taking advantage from the pond widespread circular perimeter, it is surrounded by a first section of 60 meters long: an elevated promenade that descends comfortably with views of the background mountains.
The second part -also 60 meters long- includes a wooded slope, which serves as buffer for cars and noise. Between both sections, there is a fast-paced staircase and a small open amphitheater.

ACTUACIÓN

The existence of schools, alongside interconnected amenities, brings significant flows of young people and residents. The centrality and quality of neighborhoods nearby attract families and older adults. Starting from a simple assignment for a route – a universal accessibility ramp for the original footbridge, as part of AVO's highway mitigation plan – a space for permanence and coexistence within the natural context that the park offers to the city is proposed.
The ramp improves connectivity infrastructure in a neighborhood divided by a highway. The community regains its original inclusive continuity through intensive pedestrian usage, involving not only residents but also park visitors and students from a school located on both highway sides.
