@Ronan 1 its the concrete supplier with the conveyor that is recommending the high slump of 120, so they must think they can convey it.

I believe its like these

nice, go on then where is your picture of your nice new slab?

its not being pumped, out of a mixer with conveyor for the first load to get to the back of the slab, and straight out of the mixer for the other loads.

Pretty much as the steel work is in, the BCO has been out and checked it and is happy and looking to do my concrete slab pour on Friday. its going to b a 300mm concrete (RC32/40) slab with two layers of mesh (bottom layer is 100 x 100mm grid) in it with 50mm cover, which will be pokered I have a booking for the concrete, and have been asked what a slump i want. I asked the ground work who has said 70-80, and when i told this to the concrete supplier they said it was too dry and won't go through the mesh and should have something more like 120. having never poured a slab i don't know which one to go with, or just split the difference and get 100, any ideas This guide recommends a slump of up to 90 for slabs and industrial floors https://www.geargb.co.uk/productpdfs/Guide to concrete floor applications.pdf

That reminds me, if it's within 1m of the boundary and made of combustible materials, wont it need building regs approval? https://www.planningportal.co.uk/info/200130/common_projects/43/outbuildings/2

To me it seems a bit of a pi$$ take and I would be concerned due to how imposing it is. It may be worth asking the council their opinion. The permitted development guidance has this definition of height. Height” - references to height (for example, the heights of the eaves on a house extension) is the height measured from ground level. (Note, ground level is the surface of the ground immediately adjacent to the building in question, and would not include any addition laid on top of the ground such as decking. Where ground level is not uniform (for example if the ground is sloping), then the ground level is the highest part of the surface of the ground next to the building.) This is clear that the allowable 2.5m includes the decking, and from the pictures they seem well over that. I would say that decking is at least 0.5m

This is a new build, i don't think that this included gas connection from the main, but in my case the gas main is in the road outside and if i recall correctly wasn't that much to connect to the mains

have you got any drawings / detailing, i am struggling with my floor detail and getting it to work, as below

I was chatting to a plumber earlier discussing my house build and he reckoned that the cost difference between a ASHP and a gas boiler was about £6-8k when you factor installation, for use with a hybrid mixture of rads and underfloor heating Has any one got any other sources that gives an idea on the difference in cost? assuming no RHI so only looking initial costs

Just to help, 10.4N blocs, M6 mortar, ties at 600mm cts horizontal, 450mm cts vertical.

Does anyone know of any guidance on how high each pour of a core filled (200 mm) masonry wall should be? 2 blocks, 3, 4, more? The walls will be tied, but they won't be supported from the outside.

Ouch, i brought and paid for my steel for the whole project about 3 weeks ago and am very relieved to have got it on site yesterday. Though saying that i may need more! ? What steel are you after? There seems to be a back log in bent bar at the moment.

I have one on my desk

I live next door to the site and can actively monitor what they are doing (also a time lapse camera is set up). Things have got better and and hopefully for the next bits of ground works will progress as expected (last weeks invoice reflected the reduced work on site). I have my guard up though on the work they are doing. Yesterday me and three of the ground workers got the two layers of retaining wall / slab mesh installed, me being on site getting my hands dirty seemed to progress getting the work done, also i was there to make sure it went in properly. I am going to tie in the starter bars over the weekend, and BCO / architect inspection scheduled for Tuesday morning. Hopeful for the slab pour on Tuesday afternoon / weds, and brickie's on site for the retaining wall on Monday (different firm). There is also the availability of slave labour if things get really tough (my little helper setting out mars bars, i should have paid her a proper one for her efforts)

the regs say that it should be designed for a 1:40 fall to achieve a minimum 1:80 fall when constructed. 1:40 is 0.025, so for a 6m length you need a drop of 150mm (6 x 0.025) over the 6m length.

Try condell? Thankfully i have got all my lintels sorted bar two large ones going over bi-folds, though i am thinking that i may change these to RSJ's due to the shortage.

cavity wall

I am putting together drawings for a posh outbuilding / garage, with a concrete slab and timber frame walls. This will be a posh outbuilding first and maybe a garage in the future. My initial idea for for the floor junction detail is below, this has 100mm of celotex which maybe overkill in the floor, on a 150mm concrete slab. The issue is that i want to maximize head room in the posh outbuilding, so i could either reduce the thickness of the insulation or i could bring the slab level down so the FFL is level with the outside ground, or a little step into the building. The problem is that i don't know how i would maintain the 150-160mm gap from the surrounding ground to the timber frame. Also how can i minimise the cold bridging of block at the base of the timber frame?

weep vents wider DPC to go above lintels / openings

She must be working her arse off and/or have very good paying clients.

Fair oints and i do hope that is correct

Down in the south west, brickie I have been recommended and did a house near me has quoted £19 m2 for easy solid block walls (retaining walls) and £21 m2 for external walls including openings / lintels. This is on a closed area basis, and mortar mixed on site. Seems reasonable to me

and now i have i am one of the lucky 10,000
