From a layman's point of view the East Stand should be quite simple to do-all they have to do is bolt on the pre-cast concrete bits and add the seats. All the other internal bits were taken care of during the initial build if I recall correctly. I'm pretty sure that all of the bits that would normally take time (as in other clubs' expansions) are also already in place-the base layers for the corner seats were laid along with the rest of the stadium. We were all amazed at how quickly the slip form terraces were built. It'll be a doddle...so long as the little crane things don't knacker the pitch!
Was at the Amex a few weeks ago for work purposes and after i was finished i blagged a cheeky tour and look round, I was taken round by a member of staff not a tour guide and they told me on the sly that all the materials had already been ordered in expectation of a positive planning approval. Therefore no delay on that side and should easily be completed in the close season
