The Olympic Delivery Authority has insisted that the construction of the London 2012 Aquatics Centre is on track and will in fact start ahead of schedule this month, after a recent BBC London report questioned whether the Aquatics Centre could be built.

The BBC London report on 1 July included claims that the roof of the venue, which will provide swimming and diving facilities currently unavailable in London, may be too complicated to build and that a potential supplier is concerned about the materials being considered for the roof.

The roof of the Aquatics Centre will be an innovative steel structure with an aluminium covering.

According to the Olympic Delivery Authority (ODA), the design team led by Zaha Hadid Architects have worked closely with engineers Arup and the main contractor Balfour Beatty to finalise the construction plan for the roof, including maintenance access in legacy.

The team is currently considering different types of timber cladding for the internal ceiling of the venue and the sides of the roof supports. The timber selected will be tested over the next six to twelve months to ensure it works both for the Games and in legacy before being installed in 2010.

ODA Aquatics Centre Project Sponsor John Nicholson said: "We are on track to deliver an Aquatics Centre that forms a fantastic 'gateway to the Games' and in legacy new community and elite swimming and diving facilities that London currently lacks.

The innovative building structure design is finalised and the contractor is on site and ready to start construction ahead of schedule this month.”
