Architect loses control of design as contractors work to scale back costs again

Money worries have forced another redesign of Zaha Hadid鈥檚 Olympic aquatics centre.

It is understood that the contractors shortlisted to build the centre are working with the Olympic Delivery Authority (ODA) to value the design, effectively cutting Hadid out of the process.

Balfour Beatty, Hochtief and Eiffel have been shortlisted to build the centre. However, it is understood that the contractors are asking consultants to rework the designs to cut back on costs before they submit their final bids.

A source close to the scheme said: 鈥淭here鈥檚 obviously a cost problem with the way it鈥檚 designed at the moment. It was difficult to find contractors

to bid at that price so the ODA has obviously told contractors to rework the plans.鈥�

One of the main targets for cost-cutting is believed to be the signature roof, which has already been scaled back by Hadid at the ODA鈥檚 request.

It is understood that Hadid is being kept at arm鈥檚 length from the latest design process.

In November, Hadid unveiled a severely scaled-back design for the centre, which originally had a 拢75m budget. The wave-form roof was nearly a third of the size of the original 鈥� 14,000ft2 compared with 35,000ft2. The ODA has said it will not reveal the final cost of the centre for commercial reasons.

The ODA is also working to reduce costs on the designs for the Olympic stadium. A revised outline of the project was expected to be confirmed after 黑洞社区 went to press.

A spokesperson for the ODA said: 鈥淲e鈥檙e going through the routine review as we move from design stage C to D. The design won鈥檛 fundamentally change.鈥�
The ODA claims it is close to finalising a deal with construction trade unions on direct employment of workers on the Olympic site. David Higgins, the ODA chief executive, said the deal would include an agreement on maximising direct employment and guaranteeing better conditions for site workers.
