indeed a bodge. i think the worst is the "notch" for the shower waste.

notch of all notches that isnt it!

erm what size re those joists and how far do the span between sleeper walls or bearers ??

 

[moony]

5 1/2" by 2" and they span 3.8 metres support wall to support wall they have got a wooden beam support about one metre in from supporting wall. we are hoping we can put another small steel support bean same sort of difference from other wall under joists and go about it that way - the building control officer if thats what you call him is getting back to me next week but i can see this being a site engineer visit to be honest.

take it its down stairs you can notch 1 3rd of a joist this would not bother me am a carpenter by trade and as i said before i would ply the side of the joist for some extra strength then 1" ply the floor makeing the floor a complete slab you would have a job on ur hands to get a steel plate/beam under thier to do and good as would have to be i one piece and bear 150mm on to the bearers either side

no mate its upstairs. above a dining room

and you cant notch a third of joist its against regs whether or not it would bother you is a different matter no offence intended its building regs me and my company work towards - your allowed 1/8th. but thanks for your advice on a solution i will wait until building control get back to me on this one - the support beam underneath i would think would be a better solution as your not adding weight to weakened joists.

i've seen worse! i couldn't believe it, but notches at least 3/4 of the joist depth! waiting to hear from customer about what she wants to do.
i will reccomend speaking to building control, but she will probably not like being told that serious and expensive remedial work is required.

i was planning on rerouting the pipework, and bolting lengths of joist either side of the damaged joist to give support....
would this be acceptable or should i insist on building control and maybe just walk away from this???

that shower notch is bad, looks like they've used expanding foam to sort of stick one side of the joist back. classy.

at least you dont have to buy a trap for the basin
