No no no - the delay is most likely caused by BW having to undertake a risk assessment - you know - what MIGHT go wrong - in order to satisfy the elf and safety police. Once they've done that it probably has to be approved by Mr Brown (or Darling) or whoever, sent back for a further review (the politicians way of avoiding making a decision). This process should be complete within (say) 6 months. Then it has to go to tender. Being a big job it most likely has to be advertised in Brussels (and Strasbourg, Paris, Berlin, Madrid etc etc) with a 3 month period for clarification of the tender documents. Then another 3 months for the potential contractors to send in their tender, another 2 months or so for the tenders to be examined and the contract awarded.
THEN (and only then) can the work begin. So maybe the Shroppie will be open for Easter 2011?
Cynical? Me?
