They are good. What did he charge per visit? Do you have to have 3 visits including initial topo of site?

I think its limestone type1 ish stuff for a base just to get out the mud isnt it?

Did you have a normal mix or use that trench flow stuff? Your gear flowed pretty well. Fair play to the driver I wouldnt of thought they would drive on mud like that. What time of year was it?

Also I think you have to specify a pump mix so they dont just water it down. Best bet is to hire pump and concrete off same firm or at least 2 who regularly work together.

I'm not sure about crittall I'm more talking with timber windows. If you look at one with stick on bars and one with individual glazed units you do see the light reflected differently. I'd never heard of it either before making windows to please CO

You've got to have a chat with local CO. When i was looking into it I understand it is very variable on what the individual CO thinks. Also I gleaned a lot of info off a facebook group listed buildings or something like that. This is a common query on there. Some have been successful others not.

Some CO dont like this as they say the panes dont litter the light. In other words no different reflection. A lot prefer super thin individual units on listed.

Are fibre more accurate than steel then? I always assumed the opposite. Don't tapes have different grades of accuracy? Like a, b, c etc?

Ah I didn't know how they load the original map I assumed it was os. Round here the councils still dont require topo as part of planning so you can just say dwelling 150mm above finished ground or x mm above ffl of adjacent house. When I'm setting out I just pick whatever my most important boundary is and go of that. If the house is shown 5m off the front for instance I'd pick that and if its a hundred or couple of hundred mm different at the back due to boundary features not tallying up then so be it.

If I can wrap my head around how they work I'd consider it. Whereabouts in the country are you?

@flanagaj if I remember isnt your footprint just a long rectangle? Should be easy to diy mark if so.

Thats insane 100mm on 30m was it stretching or was it just always 100mm out on the markings on the tape?

I've always used profile boards and triangulation. Tbf on the last one my laser marked the first 90deg so just double checked with the tape and all was good. Once you've got profiles for your two longest walls its easy. I could talk you through how to do it but might be better off with engineer if not confident. Its probably a mugs game anyway takes a day and usually best to have 2 people. Bet it works out cheaper to pay a pro. I'd love to have a go on one of those total stations and see how they work it must be like magic. How do they compute if site boundaries not as per OS maps?!

Yeh trenches be fine. I'd like to think now we are past the stage of hard ground frosts. I'd like to think we're past the window scraper stage tbh

I never used any in this type of scenario. Just cut a tight fit. You'll be on a flat enough surface with it being b&b should be able to keep everything nice and flat and square.

Do you have to put a slither of dpc where the pir hits the brickwork? I like the closers tbf think they are neat. Probably a cold bridge though?

Do you need se now for standard strip footings? Back in the day just used to be able to dig and refer to a tree table if needed. I have heard nowadays bco want things designed?

What do you guys close cavity with? Just so easy to order bba approved pre formed closers here. Assuming you just have concrete lintel and angle iron of brickwork. They have the thermally broken catnics here now the metal doesn't join between the two leafs.

I think 1 day with a 5 or 6 tonner to standard 1m depth and wouldn't be far off. I'd be digging on one day pouring the next. Concrete in afternoon gives you a buffer of the best part of a day. Maybe with your 2.7 allow 2 days concrete on morning of third. I'm assuming your hiring groundworker and machine separately? Bit late now but for founds I always hire man and machine as a package.

Brickwork. Last place had 150 cavity and passed 5 years ago think .18 u value. Medium dense blocks inside too no areated rubbish. Have english fabric targets changed since then? Not much noise near this plot but @JohnMo made a good point about comfort sitting near them. Mvhr yeh probably right I had that in last place and couldn't really see the benefit, think its overhyped. That said I will have it again due to needing good airtightness anyway.

I thought you meant tomorrow as in digger and muck away booked. In that case I'd crack on with stripping site and marking out any prep work. If your weather has been like here recently maybe give it a few more weeks of doing out before digging founds. We've had floods round here the ground will be quite full.

Yeh I think I would if everything was scheduled for tomorrow. Ideally starting in a month or 2 would be better to let the ground dry out but cant wait for goldilocks weather. Have you got concrete booked in for day after trenches are dug? Perhaps hire a dirty water pump or have a local place ready to hire you one.

Regardless of political leanings I think we can all agree the world is just going to be more like this for the foreseeable. I think globalisation peaked before covid. Probably doesn't hurt to be more prepared with backup suppliers/materials/options. Hopefully war is all over soon I think Iran are about finished now, probably down to 10s of missiles fired per day from 1000s at the start.

This could suit us the more I look at it. I think we'd have some better sizes than on that plan because we would be at 7.25 x 10.25 internally after plastering. 11x8m overall externally. Allowing for 375mm finished wall thickness.

Oh sorry your front is the other way round my bad! And stairs not of kitchen what an idiot I was looking the wrong way.
