In the summer of 2018, project "Oxgenyo" in Costa Rica, San José was successfully installed.

The ETFE roof cushion with a 135 foot diameter covers the central place of a spacious shopping area in the district of San Francisco de Heredia. This ETFE structure is currently the largest of its kind in the world and it combines a clear architectural language with detailed connections and a highly optimized security system.

The two-layer cushion construction with a total of 18,000 square feet is supported by a network of cables anchored in a continuous steel ring. In case of emergency, (loss of air pressure) security valves has been installed which ensure that any accumulated water is discharged immediately.
