The Education City People Mover System in Doha: DYWIDAG Post-Tensioning Systems ensure environmentally friendly Transportation
Education City in the western outskirts of Doha, Qatar is a new, 14km² district with different educational institutions. Approximately 1,300 students are enrolled at the 6 western universities of Education City. In addition to the universities, the district also accommodates several educational facilities for children and adolescents as well as research institutes.
Once all facilities have been completed, the entire campus will be car-free. The different institutes will be connected by a battery operated, 11.5km long streetcar system with 26 stations. The People Mover System will transport 3,300 passengers per hour in each direction using a total of 19 trains.
A 915m long viaduct that accommodates two parallel lanes and two stations is also part of the new route. The tracks run at a height of approximately 7.5m above ground level. The viaduct consist of a total of 10 elevated structures with 2 to 5 spans. The longest elevated structures are 125 m long and consist of five 25m spans.
DSI Middle East W.L.L. was responsible for installing, stressing and grouting the post-tensioning tendons. 90 Type 22-0.62" DYWIDAG Strand Tendons complete with Type MA-A Stressing Anchorages and Type MA-B Fixed Anchorages were used for post-tensioning the viaduct. The tendons were up to 125m long.
Furthermore, 680 unbonded, 40mm Ø, St 950/1050WR, 2.20m long bar tendons conforming to ETA 05/0123 and 680 40mm Ø, St 950/1050WR DYWIDAG Rock Anchors with double corrosion protection were used. These systems served to anchor the steel structures at the tram stops.
