Hi looking for some advice.
I am fingers crossed getting planning permission coming through on a workshop that will require building regulations.
Block work construction, cut roof. For the roof do I require structural calculations? Similarly for the footings. I have looked at part A documents and the footing looks like I can just follow the advice on there with estimation of load per m, soil type. The roof construction is less clear, as although there are span tables to timber size available they don't seem to be taking account of roof covering. I am just going for square profile sheeting so on the lighter side.
Basically I am not sure if by going and getting loads of structural calculations done this is an overkill for the building inspector and just showing that the span is less than maximum on tables is ok?
Overkill, just pick a timber that is a for a span a bit greater than what you have and that will cover it, that type of roof covering weighs nothing.
Make sure you get the foundations right because they will check this in person before you can cover them up.
What do you mean by square profiles sheeting?
Corrugated sheets or polycarbonate plastic stuff?
All my extension and loft conversion require structural calcs for the roof members providing to building control

You'd think. Highly unlikely even more so right now.
Still waiting for final sign off but photos were order of the day for foundations....even the steels holding up half my house . No one has been round. Had one phone call and had one email saying that they are not even allowed in the house ATM.
Even in warrent the only stipulated a pre plasterboard inspection for my house and that got kyboshed in lieu of photos.
My architect did say a chartered structural engineer doing the structural will make for less questions at the planning office .

I'd be cautious, my neighbour was told to redig his foundations on his garage, the inspector was quite frankly a knob not accepting that there is a strip of flint rock (despite showing him) that runs up our road and its not London claybed.. 🙄
Just to add, the garage was built as was his new house..
Your warrent will outline inspection points.
And new builds are slightly different also. The inspector has much more power over you when it comes to new build.
*Edit I'm.not saying don't do it right and to regs.....just pointing out if you are waiting on someone to show up prior to continuing building you'll be waiting a long time right now
What do you mean by square profiles sheeting?
Square profile tin sheets rather than round profile tin.
Thanks all looks like will need calacs. I'll see if I can have a chat with building control for a bit of clarity but will be easier. Should be easy pear calcs tbh.
A set of structural calcs is pretty cheap, just get that done and submit it with your application for building control. They'll then send back a schedule with what they want to inspect. I'd just email in photos when you're at each inspection stage and in my case they just email back 'looks ok, carry on'.

The calcs are simple yes
But the building control don't want to be checking your calcs they just want to see a structural engineer did it.
size of building?
Scotland or England?

AHH ,never thought of that it's more of "a competent person did X" than anything else. Much like any other part of building regs which I have had to deal with for other projects.

England 6mx10m
Having a light roof doesn't actually help for the roof timbers, as the biggest load on a roof is usually upwards, from wind suction. Something that gets missed out is tying the roof timbers down to the walls.
I would give Building Control a call and ask them what they expect to see in terms of calculations; different Councils have different approaches.
In contrast to trail rat, the building inspector came out several times to inspect our recent building work. Usually came out on the same day too. In the midlands FYI
