You'd think so, wouldn't you? But this is English Heritage...

I'm sure that any groundsman at a first class cricket club would be able to cover it in a jiffy.
Maybe a couple more to help haul the covers up the hill initially.

Makes you wonder, doesn't it?
The other scenario is that it is intended to leave the shaft empty until the base is stable enough to put the chalk in, which will be a while, if ever, presumably.
But that begs the question, if its safe not to have polystyrene in there, why did they put polystyrene in there??

I think they're clearing everything out that shouldn't be in there, so they can get an overall picture of what needs doing. Much like when renovating an old house or summat.
Skanska will have done a risk assessment beforehand I should think.

I'm sure they will have but its an assessment of risk and I doubt they can say its zero. One large area of the side of the shaft is known to have sheared away.
So how does one go about removing it? It can't be all mechanical can it?

Do they have to remove material that belongs there?
Maybe they can work round it. Unless they need to sieve it.

Well, Update 12 is out.
Entirely about discoveries in the trench. Not a word about the structural problems or the removal of the polystyrene from the centre.
I guess they judge that's of secondary importance to the peasantry, eh?
Absolutely bloody outrageous.

If the horizontal and vertical shafts meet up there should be a hell of an updraught, which will help to ventilate and dry the hill out.

Absolutely, no mention of structural problems at all, and that is of primary concern. There's an announcement of a supplementary engineering update for later this week - it better be detailed and upfront.

"There's an announcement of a supplementary engineering update for later this week"
Yes, but unfortunately the present update "focuses upon the hilltop works" but doesn't mention the shaft at all and the supplementary one later this week will explain "FUTURE progress with the TUNNEL".
So where's the explanation of CURRENT work to the SHAFT ??
