Plumbing pipe in structural Beam
(OP)
Hi,
I am involved in construction Water reservoir and Treatment plant in Alberta, Canada, as an Engineer. As per drawing, all Floor drain plumbing,3" PVC Pipe, should be place in Hunching under the suspended slab. As per contractor request, Project Team allows to place 3" PVC pipe in the beams and eliminate Hunching. Beam length is 7mt and pipe place 1.5mt form on end. Both end of beam seats on walls.
Beam 750 deep and 800mm wide. My?- Does 3" PVC pipe allow to parallel longitudinal? if yes what criteria governs to decide that. I have done beam crossing before but never place pipe n beam. Thanks for your time and really appreciate if you can share your valuable information or expertises.

Thanks for all replies,
herewegothen - PVC pipe place in beam in long direction. and it is slope too, so its varies in elevation in beam to meet pumping code requirements.
rowwingengineer-i like this idea. 3" pipe easily go through in 5" pipe but would it be complicated at fittings?
Thanks

By the way, just curious, but is this beam to be precast, cast-in-place? I would suggest really getting your structural engineer's input on this as he needs to be aware of such potential decreases in strength that he probably didn't design for.

Thanks again, I believe in your inputs.
"Hunching" refer as concrete cover around Pipe. Water treatment plant all plumbing bring it down to under the slab and cast-in place at time of slab pour, which have some reinforcement like U bars and Horizontal bars. It also make easier for plumber to U Traps for Floor Drains in the slab. I can send you photos if you want to see.
Thanks,
