The new Line 13 Jade of the São Paulo metro system in Brazil will connect the city with the São Paulo International Airport in the municipality of Guarulhos. The line has a total length of 12.2 km; 4.3 km of which will be built at ground level and 7.9 km will be elevated.
Work is divided into four lots, two of which are being built by the Consortium CST Linha 13-Jade. In these sections, DSI Prepron supplied post-tensioning systems for one of the elevated structures that will accommodate the new metro line.
The structure was built using the free cantilever method, and three successive cantilevers were post-tensioned using strand tendons.
