As part of the Public Transport Infrastructure Corridors – BRT Lot 3 project in Luanda, GWIC provided Engineering Design services for the construction of two major road viaducts. The first, located at km 8+400, featured a 21.46-meter wide deck with a span modulation of 2×25 meters. GWIC proposed an alternative design with a deck composed of 10 reinforced and prestressed concrete girders. The second viaduct, at km 5+600, was designed with 12 prestressed concrete beams, for which we suggested a variant solution using five reinforced and prestressed beams. This project enhances the city’s public transport infrastructure, supporting future growth and development.
