The “Multiplaza la Felicidad” mall with an investment of USD 270 million, will be a 182,000 m2 structure. The steel structure is built with 13 covers in two levels (N+19.2 m; N+26.73 m), an area of steel deck for the technical part and metallic bridges between buildings. The structure is made of drawer belts, fully filled beams, "C" perlines resting on concrete elements or angled trusses between concrete or steel columns (circular and square), trusses formed by filled profiles (I ) for upper and lower strings, parallel and diagonal by angular profiles. Wherever possible, the unions of the structure were screwed. For Industrial Conconcreto, this mall represents a challenge with the client’s requirements in terms of estimated time of execution and the simultaneous execution of the activities.
For Industrial Conconcreto, the implementation of this technology represented around 20% in time saving for the manufacturing and assembly steps, allowing compliance with the client’s requirements for the last steps of the project.
Moreover, this technology enabled strategic planning of the hoisting of every element, and study of the contingency plan of heavy weight element assembly: it has been achieved with the analysis of each element’s characteristics that Tekla Structures shows. For the covers with a complex architectural design, Tekla Structures made it possible to show details like curvature, connections, position and inclination of elements and to optimize the manufacturing time and assembly of the structure.
What made the project successful
The ease of visualization of the interferences between the concrete and steel structures, to envisage the propriety of the architectural elements, made it possible to achieve a 20% improvement in building and assembly processes.
