Gateway Towers on The Pearl, Qatar
The Pearl is a 400 ha artificial island located 330 m from Qatar's east coast and approximately 11 km northeast of the centre of Doha. The island is divided into ten quarters and offers room for many new family homes and apartment buildings, schools, kindergartens, hotels, shops and restaurants.
One of the ten zones on the island, the 13 ha Abraj Quarter, accommodates 200 new town houses and seven apartment towers. Two of these towers, Gateway Towers AQ 01 and AQ 02, flank the access road to the Pearl, thus forming the island's gate.
90,000 m² of post-tensioned flat slabs
The slabs of the podiums, mezzanine floors and floors with a total area of 90,000 m² were built as post-tensioned flat slabs. The joint venture consisting of DSI Middle East W.L.L. and DYWIDAG-Systems International GmbH, GBU, Germany, was awarded the contract for the production and supply of strand tendons including approximately 8,000 flat anchorages for Tower AQ 01. Approximately 400 t of strand were needed for the tendons.
As the subcontractor for post-tensioning, DSI Middle East not only supplied the posttensioning systems, but also supervised the correct installation of the strand tendons on site, thus ensuring that construction proceeded smoothly.
