David Higgins, chief executive of the ODA, defended the new-look stadium, asserting that both the ODA and delivery partner CLM think it is an improvement.
Higgins said: 'This is a simpler structure, which is much more sustainable. There is a lot less weight from the roof. We all think it is a better design, and we all think it is a great enhancement.'
The redesign has seen the roof shrink from 35,000m 2to 14,000m 2, and the wave-like 'dip' has disappeared.
Although Higgins has maintained the reasons behind the redesign were not due to cost, it is clear the new designs will be cheaper to build.
And Higgins has admitted that a key reason behind the redesign was to 'reduce the risk' of building the more complex original.
