Colombo Center Roofs

Lisboa, Portugal

Date: Juin, 1997
Maîtrise d'ouvrage: Sonae
Mission: detailed design and construction support
Architecte: Fernando Silva

The roof of the Colombo Shopping Centre was built over an already existing swimming pool, with a covered surface area of 3,100m2. The main condition required in the design was simple dismantling of the structure.

The tensegrity-type structure consists of two cable frames: an upper pressure cable, a lower suction cable and a central shore.
The cables are anchored to masts stayed to the existing structure.

Each cable frame covers a span of 15.0m.

In order to permit manual assembly and dismantling of the structure, the central shore was made of epoxy fiberglass.
