Connecting layers of steel mesh in foundations

I'm thinking that every 1m, with the high chairs fixed to the meshes would be fine? I'll decide on the day, depending how much sag there is (Or get the engineer to spell it out).

1m sounds fine but yeah, eye it in, and wouldn&#;t hurt to get your engineer to confirm.

Dare I ask, where there is a stepping in the foundation, should I be bending some 8mm bars and fixing them between the differing height bottom layers, and top layers?

That&#;s a question for your engineer as they should definitely provide a detail for this, but yes, you need to maintain continuity at the step so tying the bars together is essential.

How to Create a Cast Iron Prototype?

My only concern going back to the engineer, is they seem to over specify..... neighbours who have managed to not need an engineer have built without any mesh and years on it 'seems' to be fine.

Have you had a ground investigation carried out? There may be something in the report that guides the engineer towards specifying reinforcement in the strips.
Reinforcement in strip foundations is usually found where there is a risk of differential settlement, or where the foundations are likely to bear onto particularly weak or loose ground.
It often seems like engineers over-specify, but usually it&#;s working to within the constraints of the British Standards or NHBC Standards (which most engineers refer to even when there is no warranty provider).
Plus you only get your fingers burnt once or twice by cutting a design too close to the bone and after that you add a little extra comfort factor
