The chosen thickness of concrete is very generous because the forces to be applied to the structure are unknown.
It seems prudent to allow a very generous margin.

No active heating or cooling of any kind is proposed.

Two electric dehumidifiers each of 250 watts consumption are proposed, I doubt that 500 watts for 7 hours a day will noticeably increase the temperature.

The better types of dehumidifier work correctly down to about ten or twelve degrees.

The facility is intended for disasters in general, not just fallout. Air raids with conventional bombs, tornados, civil unrest, plagues, chemical attack, invasion etc.

I am not involved in the design or construction, but will be doing the electrical installation.

With modern day satellite surveillance I would have thought that the Russians and the US would be fully aware of the construction and it would go on someone's target list. It would be thought of as a possible military asset, just in case, to my mind. With modern bunker busting bombs they will get through most concrete constructions so spending on lots of concrete would be a waste of time.

If there is a war or disaster on such a scale that the bunker has to be occupied, and provided it isn't bombed, it is likely that all other surface accommodation would be devastated and it will become a long term home. Assuming that it has provision for power and the ventilation is kept going it will be a very cold home, at least the levels of thermal comfort will be low because the concrete will remain at ground temperature, so I would put at least some insulation around it.

I have a largely uninsulated cellar and I know how cool it feels but then it was built for cold storage not occupation. I also had a client who built a partially covered, on two sides, uninsulated cellar and converted it into a living room. The room was abandoned and used for storage only because it was too cold.

Whilst some of the work could no doubt be seen by a satellite, I doubt that it would be considered very interesting, remembering the enormous numbers of large excavations that take place all the time.

A large water reservoir is being built at the same time, to water animals and crops in time of drought.
Seemed sensible to combine the two projects, if only to spread the cost of buying a second hand excavator.

I expect every missile or bunker busting bomb in the world is already targeted for a target much more valuable then any preppers bunker. After all a weapon system has to destroy material costing more then it cost and few of us will ever build a bunker costing more then $300,000 and guided missiles and bombs cost a lot more each then that.
The reason to hide a bunker is to protect it from scavengers that would try to break into your bunker and take it and it's supplies from you. If they don't know it is there they move on by. but if it is known they can look for the vents and supply lines and smoke you out.
Who knows where it is?
The people that build it for you.
A problem as old as the pharaohs of Egypt and you don't have the option of killing all the workmen when they complete the job that they used.
Whatever you build you need some protection plan that no one that worked on the project knows about and will fall victim to when they try to force their way in. If I had a really neat plan to accomplish that I certainly would not reveal it here.

This is not my bunker.
I have taken care not to reveal the location.
It would be a reasonable assumption that it is within a days travel of North Somerset, but that includes about half the country.

A fascinating read - I read it in one sitting - is A Doctor's War by Aidan MacCarthy. Despite horrendous privations and encounters, he survived long enough to be in a concrete bunker in Nagasaki as the bomb dropped.

Those in the bunker who were looking out got blinded. He was fortunately not looking directly out and only perceived (what luck he had) a blue flash and the magnesium-type light that did the eye damage, plus of course the sound of the explosion, which was then followed by a silence.

The bunker was rarely closed because of poor ventilation.

An occupant looked out - almost straight after the hit! - and saw how everything had been carbonised.

MacCarthy helped who he could, stood in the black rain etc. He survived the radiation despite being in fragile condition following years of Japanese brutality and deprivation.

A great story.
