Well the SCC looks like it saved a lot of work. Was it expensive? Is the next pour to a different level?

The stainless steel ones seem pretty good. I had one fitted and it stopped the rats and has not caused blockages. Some of them have a mechanism that allows them to be fitted fairly deep in an inspection chamber.

We put standing seam on a roof and the customer had solar added. The were fixed by brackets that clamped onto the standing seams. The roof actually had a slight fall to north but it still worked fine. The standing seam was Kalzip type.

Agree with @Spinny if the rule was not around until 2023 your steel was already in. Point this out to BC. You can't comply with rules that did not exist at the time.

The chamber is fine. The old chambers with the traps often get blocked and are not used now. The rat blockers fitted inside the chamber work well.

What is the contractor's maximum allowable moisture?

I think the rules are about right. The planning officer can ask for further details of anything relevant if required. Measuring and detailing the height and position of all surrounding buildings, rooflines, eaves, windows, ground levels etc. is pointless for most applications.

Well that was fairly quick once you tracked them down. That looks a great location. Is it isolated?

It depends on what is around you. Sometimes full elevations of nearby buildings, always drains, covers, inverts, pylons. Our architects just use 2D as you don't gain much with 3D and it adds to design time.

Rendered concrete block outer leaf, 50mm cavity, Rockwool insulation between 140 studs, 40mm PIR, 25mm service cavity, resilient bars, plasterboard. Inexpensive and very effective. Less than 400mm.

If that is the case, make no provision for them. Do not suggest to tenants that they are authorised to install batteries. A world of liability for you.

Here you go @PSC88.

With a straight flight it is simple to do a bit at the top or bottom or alter the pitch. No issue.

That is dreadful. You need to use the main flow of the chamber for at least one junction. Use a smaller IC, add 45s to the main inlet and outlet. Move the chamber down and right. If you want I can do a sketch.

No. I keep a key for each of the neighbours and have often been called on to let them in. Even taking the bin out can result in being locked out.
