Overrunning by a year is a hell of a fuck up, lad I used to play football with has been down to work on it a few times and always said it's a complete shit show down there. There's got to be more to it than they're letting on, no way sprinklers are holding it up to March unless they've only just decided they need them and have to try and install around everything else. Last time I looked on their site webcam they still had multiple tower cranes up so there's a hell of a lot more left unfinished than a sprinkler system.
