Cubierta Voronoi – Membrane cushions roof structure

Cubierta voronoi is the first ETFE roof in the history of Mexico. The project was conceived to be the meeting point of the new shopping mall in the neighborhood of San Pedro Garza Garcia, Monterrey.

The structure consists of a tree-like steel masts which support a “honeycomb” covering steel structure. The panels of the honey were covered by ETFE cushions, which are transparent on the bottom and white on the top. The first project, so its name, was a Voronoi structure, i.e., the surface described by the roof was divided into panels by the algorithm developed by Mr. Voronoi. This gave a very nice and aesthetic structure, but far away to be built within the budget and time proposed by the client. Because of this we rethink and redesign the project, to be able to achieve the schedule and budget proposed by the client.

In this way was designed a free-form steel roof which was divided into a honeycomb structure. The big achievement of this design was to build a freeform roof only with 5 different cushions. In this way, the production process was accelerated and costs for the construction and planning were reduced. Also, the assembly process was standardized, and the whole 100 cushions (1.600 qm) were mounted in only 12 days.
