| Major marina project completed in Portland  The UK's largest and most sustainable marina of its kind has been completed at Osprey Quay in Portland Harbour, Dorset. Dean & Reddyhoff's £27 million, 600 berth Portland Marina, designed and engineered by London-based Atkins, has been built on a former Royal Navy Air Site (RNAS) and is part of an overall site-wide masterplan being delivered by the South West Regional Development Agency (SWRDA).In addition to providing some of the most state of the art facilities in South East England, the marina is set to play an important role in the sailing events for the London 2012 Games when its on-shore facilities and 250 of its berths will be dedicated to the occasion. Prior to the Games, the marina is also an approved training centre for Olympic teams – the neighbouring Sailing Academy is home to Team GB, and the Royal Yachting Association (RYA) has based its training camp at the marina to support training ahead of the Games. Portland Marina has no natural inlet to provide shelter for its 600 berths. Instead, an 860m-long breakwater has been built in order to safely house the network of pontoons that will provide the moorings. While a breakwater built from boulders of rock may not seem like a precision structure, in practice its design and construction required painstaking planning. write your comments about the article :: © 2009 Construction News :: home page |
