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.

Ours have key access externally and thumbturn internally but when the door is shut, bolts in the door automatically activate, so if you shut the door from outside you can only get in with the key.

We have slam lock doors from RK Doors. If the door shuts behind you, you need a key to get back in. There is no lever handle on the outside.

From the photos I cannot see any cracking or damp that would raise any concerns.

I don't think that is correct. 40x wire size is what is expected. I have never been asked to do 600mm. How would the 1200 x 2400 sheets ever work?

When the plans are submitted to BC they will do a plan check to let you know if they comply. I think that to comply each room either leads directly to the protected staircase or is on a corridor that is part of a protected escape route.
