Was wondering what the logistics are in relation to installing the first floor posi joists. They are obviously built in, so I assume they are fitted and then the scaffolders erect the bird cage?

We originally decided on the left, but that has changed to the one on the right. The left is more muted though 🤔 Yes. We could only source yellow or a different yellow here in Hampshire. I wasn't planning on doing that?

I have the scaffolding company coming around this week. The brickies have told me to get the first floor joists in and chipboard flooring and they'll use trestles. This approach is great as I save money on having bird cage scaffolding, but given we are using 15kg medium density blocks internally, I'm concerned about the amount of weight when they load out the blocks. They said they will put acro props under the floor joists, but I'm concerned it's not a great idea. What have others done?

So after 6 months of delay due to one shoddy bricklayer and another one who was shoddy with a massive 'I'm the best' ego, it is finally third time lucky and the two guys we waited 6 weeks to start, take pride in their work and are really approachable when you want to ask a question or raise an issue. Just how it should be. Being behind is a pain though, as it will mean I will be cutting the roof and installing the standing seam roofing most likely in November. But so long as it doesn't get too wet, it might be ok. Here are a few photos. I made a jig up to cut the insulation at the angle of the cavity tray and I was chuffed how it turned out. A rather laborious task though, but I said I would get the trays and insulation all ready for them I also knocked up probably 12 different mixes over the last few months. We tried 5 different sands, grey cement, white cement and lime ...., but non of them really worked and they were either too grey or too yellow, but we kept searching and finally found a local firm in Thatcham who had some sand from a quarry a long distance away. The colour looked like it would work and as soon as I mixed up the 5 sand, 1 white cement and 1 lime mix, we both said "that's it". Sand cost us about £90/ton, which is not cheap, but I didn't want to be looking at the house thinking "I don't like the mortar colour". Here are a few pictures of progress from the last two weeks.

Thanks @SBMS I will save that schematic and pass to the heating engineer when I find one.

I assume that must make the whole system design much simpler. I suppose the only down side is that you won't have rapid cooling to hand and if you have a lot of glazing, then on really hot days you may struggle keeping the rooms cool?

That image appears to have disappeared and is just a broken link

I have spoken to a few local ASHP installers in Hampshire and the moment I mention to them about using the ASHP in cooling mode and having a split system which enables the UFH to be run above dew point in the summer, but have the upstairs fan coils with condensate drains to run at a colder temperature, they just tell me "No, you cannot do that". Now, I am sure I have read on here, that people are doing just that. If anyone is doing that, do you have a diagram or even a contact in the Wiltshire/Hampshire/Berkshire/Surrey area of a heating engineer who know and can do what I am trying to do.

All required because of level thresholds

It ends with third SE stating that wind posts are required.

Will Keystone and IG supply directly as I've currently had a quote from Strukta who gave 84% off list.

This is what I have done.

I just want a second opinion on the below as the implications are significant and I'm struggling to understand the proposed wind posts locations and also the excessive amount of ladder reinforcement at 225mm centres. The internal block leaf is 7N medium density.

It's a shame, I cannot say that to building control.

I am trying to understand why you install bed joint reinforcement in the 2nd/3rd courses of brickwork above a window and door opening when you will have a lintel that is going to provide the lateral strength and stop the brickwork from bending inwards? Keen to understand why that thought process is obviously wrong.
