Design and build, or early contractor involvement, fail where the risks are transferred too extensively and/or where the contractor is given limited opportunity, or reward, to really innovate, and thus create best value.
If traditional contracts re-appear, then I can see the scope for alternative designs, of which we have done hundreds, simply re-appearing also – each contractor will want his competitive edge. All that happens is that the original design effort is partly wasted – not an efficient use of our industry's precious resources.
Design and build, with consultants really working closely with contractors, in a truly non-confrontational environment, will always generate best value, as long as the risk profiles are sensible and the rewards for all are achievable.
