Construction works are currently in progress on this scheme.
King Abdullah Financial District (KAFD) station is one of the four main stations of Riyadh Metro, thought to be the biggest elevated metro transfer station in the world at 32m high, 42m wide, and 232m long, it is raising the bar for architectural design and engineering, is currently taking shape. Located west of King Fahd Road adjacent to the under-construction KAFD, the station will serve as the main interchange for Riyadh Metro, connecting Lines 1, 4, and 6, with skybridge access to a separate monorail system. Designed by Zaha Hadid Architects, KAFD station features a complex geometric façade designed to resemble sine-waves. Against the backdrop of chrome and steel skyscrapers, the metallic curvature forming the glass-reinforced concrete façade helps the station standout as an architectural landmark of the future. Murray admits that the engineering behind the façade is equally impressive. One of the interesting things about this project is that the structure is freestanding over the station and ties in at ground level. As the external steel structure weighs approximately 4,237 tonnes (t) with a further 2,785t for the interior steel structure, transferring the weight loads directly to the foundations is an impressive feat of engineering. The pieces for the façade are made from curved steel initially welded in the UAE before being exported to Saudi and welded on site. During this stage the structure would sag by as much as 30cm and each side of the façade had to be built up at exactly the same time to prevent any temporary imbalances. It is the only station in the network that will have underfloor cooling. The idea here is to prevent hot air from rising out of the ground. Plans are already in place to recycle and retreat wastewater and the KAFD station may add solar power systems in the future, something that will support Saudi Arabia’s vision to a scale-up renewable energy. The station also has a smart city-style ENVAC system to transport waste across KAFD to a site where garbage is compressed, treated, and segregated. With seven elevators and 26 escalators, as well as two skybridges, people flow is something that seems to have been adequately taken care of. The station will also have a number of shops, two levels of parking, potential future baggage handling systems, and two prayer rooms to provide passengers with a range of services at the Riyadh Metro’s main station.
