Together with architectural offi ce Rafael de la Hoz Arquitectos, INES Ingenieros Consultores has developed the detailed design project for an offi ce building located in the district of Las Tablas in Madrid, for the real estate group GMP. INES Ingenieros has been responsible of the development of the project and site supervision of all the foundations and structures tasks.
The building shape has been adapted to the geometry of the plot; the plan view of all the above ground levels have triangular shape with chamfered edges. It has 5 over ground levels, ground level and one basement.
The main singularity of the building is the disposition of an external structure, placed in the perimeter of the over ground levels, solved with a truss with rhomboidal mesh, where over ground levels are supported, with hollow steel sections. Intersectioon points of the mesh are quincuxed between consecutive levels; separated every 8,10 m they are used as support ng points for the over ground levels. All the elements of the truss have cross sections of all dimensions of 400 mm x 800 mm due to architectural imposition.
In order to provide flexibility to the building spaces, no columns have been placed in visible locations, except for 4 tubular columns placed in the chamfers, all others are embedded in separating walls of the vertical core. Horizontal structure is supported by these columns and by the external trusses. Typical span is 8,10 m x 15,40 m. Horizontal structure is solved with mixed steel-concrete elements (steel beams connected to a concrete slab).
