Chas & Jazz have got it about right, someone like Chas could communicate directly with Irving to find out exactly what needs to be done so things like access at both ends can be sorted. Then formulate a plan for the work to be done so it can be project managed to ensure everything gets done.
Realise that there are a lot of people who want to help but don't forget this is just the beginning & there will be plenty more oppertunities for people to lend a hand. I can't lift anything heavy & have 2 cracked ribs just now anyway so as much use as a chocolate firegaurd for something like this but sure I will get a chance to help out with something latter on.
