Having a 2 storey extension done, builders haphazardly measured the floor level and despite saying better to come in under as better to make up height when they knocked through new floor level was good chunk higher - why they didn't knock a pilot hole through despite suggesting it is a mystery. The second storey and roof is now on and last week whilst I was away they laid new floor, didn't realise just how much higher the new joists were. The structural engineer had specified 44x195 C24 ceiling joists @ 400mm c/c. Looks like they have used 8 inch joists a block width apart, to get the floor lower they have cut about 4.5 cm off the joists so the remaining joists are about 17 cm, obviously going to be a nightmare to rectify now, looking at span charts online they are too small. There is an ensuite and main bedroom going in that room. Here are some pictures :
Would have been so easy to have come one small brick lower had they measured correctly, annoyingly didn't look the other way to see if joists are resting directly on steel on the other end, very frustrating, what would people recommend in this situation ?
Many thanks,
Lawrence
