Issue is customer intended to board the loft for storage but the insulation specified is taller than the joists. The contractor didn't plan to pack up the joists to allow for boarding but the customer expected that to be included.
Perhaps you should deal with the OP's builder instead as you know whats going on. I bet the builder does not.
Anyway, it looks like the builder was not boarding the floor nor told it was even going to be done, so how is he to be aware of the need to reduce the insulation thickness?
In my simple mind, I would be grateful if I paid for 90mm of insualtion but the builder gave me 10% more with better efficiently. Then, when I came to board the loft, I'd just put a little strip of wood down on the joists. No fuss. But that's just me.
Sometimes you have to apply a bit of common sense, if 90mm insulation was specified and 100mm fitted (for what ever reason), shimming the joists to the correct height should have been a given surely?.
The issue isn't about whether they should be shimmied to the correct height, it's about what the correct height is (which in turn is about whether it is common ground that the loft should be ready for boarding as storage)
There are too many assumptions flying around, the difference is simply the builder assumed the loft storage creation was entirely someone else's job as it wasn't explicitly specified as being partly his job.
It just shows how important it is to clarify the job at the start. I think most lay people would expect there to be walking access in a loft but I can see the builders view is a different one.
A good reminder to anyone to get their general living requirements down at the head of the brief.
Eh, WTF? Why?
Drawings state: "lay 100mm quilt between joists and 200mm across joists...."
They don't state "the client may want to store the fake Christmas tree and the silver and red baubles in the middle of the loft so be sure to contravene the heat loss Building Regulations and pi$$ of the building inspector so this can happen...."
A walking platform would be deemed structural and thermal design and considered an extra or be listed as a deliberate specific item.
noseall the point you have just made is what 99% of us do in real life! I have never lived in a house with an unboarded loft and I doubt many have. I think it's fair to say most lay people want some boards in their loft.
I get the point it wasn't in the spec and would be an extra but I think the point Ian H is making is that the client has now been prevented from boarding his loft. By his builder!
