LONDON OLYMPIC bosses this week revealed revised designs for the 2012 aquatics centre, with the venue's roof reduced to just 40% of its original size.
The revelation came after Olympic Delivery Authority (ODA) chief executive David Higgins last week said that high steel prices would affect the use of the material throughout the Olympic Park.
'We will be looking at where we can design with less steel in this project using smart design, ' said Higgins.
The area of the pool's undulating steel roof has been cut from 35,000m 2 to just 14,000m 2 in a move that will save both construction and operating costs, making it a much more sustainable venue, tting in with the ODA's original brief.
Structural engineers told NCE in January that savings could be made by redesigning the roof.
Their comments were made following culture secretary Tessa Jowell's decision to review the venue to clamp down on its spiralling cost (NCE 12 January).
Reducing the roof has allowed the masterplanning team to run an entry bridge to the site next to the aquatics centre. A temporary extension of the roof during the Games will provide a covered walkway for the bridge, the budget for which can then be incorporated into the aquatics centre's, further relieving cost concerns on the venue.
Priced at £66M when Hadid won the design competition in February 2005, Higgins refused to say what the pool's revised cost would be.
Hadid's practice is working with pool specialists S&P architects to design the inside of the venue, with Arup as structural engineers.
