No update 12 yet?

Still waiting.
One thing (apart from many others) needs an urgent explanation IMO -
why is the central shaft being emptied of polystyrene now when it was always scheduled to be done only when the base had been fully stabilised?

Has it now been decided that the only way to stabilise the centre is accessing it from the top? Surely not?

The only other reason I can think of for going out of sequence is finance. £600K computes at maybe £50K a week so time's money. Is it thought better to utilise the plant and personnel on doing something rather than nothing since they are being paid for?

That would make sense, but only if it wasn't a more damaging or less effective solution and wasn't taking an extra risk (for both those involved and the archaeology).

Reassurance specifically about that is in EVERYONE'S interest, surely? I'd ask them, but what's the point?
