richo106 Posted September 25, 2022 Share Posted September 25, 2022 Hi I have been to my project this morning and just checking over a few things and after a thought I wanted to check my foundations. The foundations were doing between myself and civils guy but I now think they are about 6/8inch out as the architects drawings are slightly wrong and we used this as a reference point typically. what options do I have? Can I add another strip next to the footing? I know not ideal but this is the time to do it now any ideas/advice appreciated Link to comment Share on other sites More sharing options...
Dave Jones Posted September 25, 2022 Share Posted September 25, 2022 Assume you saying they are 6" to 8" out, not insurmountable ask your brickies. Link to comment Share on other sites More sharing options...

How would they overcome something like that though? That’s give me a little hope haha but would be very interested to see how they could do it Thanks Link to comment Share on other sites More sharing options...

Too close together or too far apart? You might be able to nudge that by building to the edge of the foundation rather than the centre. Or a compromise and offset the build as much as possible and accept the building might be slightly too big or too small and adjust. Wrong position? i.e. the whole building is 150mm offset in one direction? Who would notice? is it going to breach a planning condition? will anybody bother to measure?

richo106 Posted September 25, 2022 Author Share Posted September 25, 2022 It needs to tie in with the existing building as it will be a double storey extension and the side wall needs to line up. below is a photo of where the wall needs to be Can only see where the line of the wall needs to be now we have taken part of the existing garage down Link to comment Share on other sites More sharing options...
Mr Punter Posted September 25, 2022 Share Posted September 25, 2022 If the new foundations are 600 wide, are you off the foundation with one of the leaves? If that is the case and you don't want to reposition the new wall it may be best to break it out and start again. If it is just a small section you may get away with digging out next to it. If BC are aware they may ask you to resin some studs into the side of existing to a design by your SE. Link to comment Share on other sites More sharing options...
markc Posted September 25, 2022 Share Posted September 25, 2022 Solutions aside, if a part of the new should tie in/line up with existing then that should have been your starting and setting out point, not and Archi drawing. Link to comment Share on other sites More sharing options...
richo106 Posted September 25, 2022 Author Share Posted September 25, 2022 (edited) Hi Mark It was a big thing that was overlooked but we are at the position in the build to correct this/decide a solution now I have attached a couple of pictures that show the arch drawing and then how it should be and with the foundations in position currently in red. The critical thing is matching up with the existing side wall as the extension will be double storey Hindsight is a wonderful thing as when measuring the other way we thought the measurements were but i went with the advice of the civils guys...to my annoyance I wish i followed this up earlier Hope this makes sense Top picture is what is like now, showing the foundations installed (600 wide) and also the nib of the garage that i have moved Bottom pic - arch drawing Edited September 25, 2022 by richo106 Link to comment Share on other sites More sharing options...
ProDave Posted September 25, 2022 Share Posted September 25, 2022 Sorry I am still confused. Can you post a picture zoomed out showing a lot more of the building? All I am seeing is the corner of an existing wall, forming an external corner, and the way you have the bricks set out that will NOT line up with the existing outer edge of the existing wall. So I must be miss understanding the picture. also I don't on the drawing see an external corner with a new wall joining on in the same direction? All I see is you want to join an extension on so it is NOT in line with the existing? Link to comment Share on other sites More sharing options...

ProDave Posted September 25, 2022 Share Posted September 25, 2022 So you WANT the new wall to join offset from the existing? Why? Link to comment Share on other sites More sharing options...
joe90 Posted September 25, 2022 Share Posted September 25, 2022 If you were removing the wall between kitchen and new snug I would understand why, but as @ProDave says why? Link to comment Share on other sites More sharing options...
richo106 Posted September 25, 2022 Author Share Posted September 25, 2022 No I don’t want it to join offset, that bit I have moved on the drawing is how it is in real life. But as I will be adding another floor on top of it all, the outer walls need to line up. I am either explaining this terribly or I am being very daft Link to comment Share on other sites More sharing options...
ProDave Posted September 25, 2022 Share Posted September 25, 2022 So your architect got it wrong? The plans show the inside of the garage wall lining up with the outside of the continuation of that wall. The reality shows the last bit of the garage wall offsets to the right compared to the rest of the wall. And nobody noticed that detail was wrong until now?

Add a strip next to the footing to widen it, but also add concrete depth over the existing footing to tie them together, otherwise the two strips of footing might move differentially and you don't want that. Effectively you will have thickened the footing a bit which shouldn't be an issue.. Link to comment Share on other sites More sharing options...

joe90 Posted September 25, 2022 Share Posted September 25, 2022 Or dig out, drill into existing footing on the side and wallop lengths of rea bar into it leaving enough proud into the new footing along side the existing to tie the two together.

Radian Posted September 25, 2022 Share Posted September 25, 2022 This is the typical kind of balls-up that happens when the architect's drawings don't reflect reality. Personally I'd be talking to the person who drew the plan and discuss issues to do with liability for the extra expense the error in capturing the building layout will incur. Perhaps one of our tame in-house practitioners might like to comment? Link to comment Share on other sites More sharing options...
joe90 Posted September 25, 2022 Share Posted September 25, 2022 (edited) Well despite me designing our build i used an architect to transfer my pencil and paper drawings to CAD for the council application, he got it wrong three times before I accepted it as correct 🤯 Edited September 25, 2022 by joe90 Link to comment Share on other sites More sharing options...
