For the structural steel I insisted the company come out and measure . Most weren’t interested in the trip even if relatively local . So I offered one £100 for a site visit . They came out , measured and supplied the steel . Best £100 i’ve spent... Especially if your build doesn’t match the drawings to the mm ...

idunknow Posted July 11, 2019 Author Share Posted July 11, 2019 yes i am feeling that way too i have spent a lot of time measuring up how ever there is in my opinion now an issue with what steel is going to or even possible to fit above doors because all beams are connected would mean they all are about 2100 above finished floor level i think that's to low its only at this stage i noticed incorrect details for position of plate and a size stated at 8mm when its 12mm these professionals have let us down you put a lot of faith in people and set yourself up for a lot of disappointment thanks for your time pocster i am worried that i will have to start again with new so called professionals because i don't think it will get past BC to fit another steel under RHS beam No 4 cheers 1 Link to comment Share on other sites More sharing options...

Jilly Posted July 12, 2019 Share Posted July 12, 2019 (edited) Same thing happened to us when we built our garage many years ago, the steels were incorrectly measured, I realised the moment I saw them (and I can count to 4 when only 3 turned up....). Someone I know who did a self built recommended getting the steels cut on site because measuring with accuracy is so difficult, which saved him an awful lot of money and headache and I think I would do this in future. There are a lot of unforeseen circumstances with building, right right from the first pencil chewing and one bit of legislation seems to fight another, so there are no straight answers in how the solutions are managed. BC are used to working with builders and architects to solve problems, so you will find a way through. Edited July 12, 2019 by Jilly 1 Link to comment Share on other sites More sharing options...
Vijay Posted July 12, 2019 Share Posted July 12, 2019 At least I now know my SE isn't the only crap one out there lol I've been dealing with his mistakes for the last 5 months and always does my head in when he sends revised plans which still have such obvious mistakes. I would honestly say it's been the worst part of my self build 1 Link to comment Share on other sites More sharing options...
idunknow Posted July 16, 2019 Author Share Posted July 16, 2019 o dear they have us by the never nevers thanks for your replys if we didnt have to adhere to BC then i would apply common scene and get it built its obvious now that there opinion is just that ive seen guys on here do the calculations my SE just said put a beam on top of abeam to get my heights even i know there's implications to that gonna crack on BC have passed his dribble so im gonna say i did what it said on your tin Link to comment Share on other sites More sharing options...

Jeremy Harris Posted July 16, 2019 Share Posted July 16, 2019 For retaining walls, all SE's in the UK are supposed to just follow Eurocode 7. It's not hard to use; I did a couple of designs myself using it, before I realised that I had to use an SE in order to get the thing signed off, or use one of the prefabricated block systems and get the sign off via their design services. The snag I found with the block systems was the cost and the room most of them took up. For us they were all more expensive and a lot thicker than the reinforced 215mm hollow block wall we ended up using, plus the block wall was a lot thinner, so gave us more useful room at the back of the house. Our SE was very good, and only charged us £300 + VAT for a full drawings package, specs, steel cutting list etc. Link to comment Share on other sites More sharing options...
K78 Posted July 16, 2019 Share Posted July 16, 2019 A thinner solution at my height was really expensive. I would have still needed a wide foundation too. My wall was cheaper than than SE design for prefab, bolt down panels and kingpost. As it is a incline gravity retaining wall, the design was really simple. Ill try and dig out the idiotic design that I had done when I first bought the plot. It was a poured concrete retaining wall and house foundation in one piece. He spec’d £22k of rebar.

Jeremy Harris Posted July 16, 2019 Share Posted July 16, 2019 The foundation for ours is wide, 2m at it's widest, but it misses the rear of the house foundation by about 400mm, and we still have around 1.6m of space around the back of the house. Had we gone for a battered back block wall (Stepoc or similar) then it was going to end up a lot wider at the base, and make it really difficult to get enough space for access around the back of the house. Our 215 hollow block wall is vertical, and "only" 430mm deep at the base, and 215mm of that is under our neighbours garden. The top of our wall, where it forms the boundary with our neighbour, is only 215mm wide. As the side of it facing the neighbour's garden is the boundary line, we've only lost the 215mm thickness of the hollow blocks, plus 15mm or so of render, between the boundary and the house.

idunknow Posted July 17, 2019 Author Share Posted July 17, 2019 yeh my actual issue were to start SE has now said to sit a 203 UC 86 on top of 250x150x16 RHS which is supported by posts 100x100x10 SHS however he has no opinions on how to fix these together 1 Link to comment Share on other sites More sharing options...

Sitting a 203 on top of a 250 clearly creates a point load, has that been factored into the design...? Out of interest, how much are you paying for this SEng service and where in the UK are you...? 1 Link to comment Share on other sites More sharing options...
