Not just held up but held down, make sure they are really secure or they will float like a boat on the pour.

with that said is the wire down yet for the concrete? if so either zip tie or use baling wire to hold them down to the large mats of wire on the ground..also you can plug the drain and fill them with water to prevent them from floating...

I would recommend you don’t do that and let the pour get done all in one shot. You’ll need to be there to supervise it. Some finishers don’t give a crap and will mess it all up.

Make sure your load requirements for the grates will support 30-40 ton firetrucks loaded with water tanks and lots of equipment.

The ones we put in were pre -sloped, we had a nightmare holding grade as code required a oil separator be installed on the job.

I would say work with your supplier as to ordering all parts as necessary and if the floor is not poured yet let the GC set the grades and have them sign off on the drain install and concrete spill protection before before pour is made ... take photos of all work.

Make sure there is no direction disclaimers. IE cross the drains with the tires -- not drive along the drains [and on them] ???

Of course follow specs for space under drains. Usually 4” for 4” and 6” for 6”. We also put 3/4 plywood in the tops. Finishers will definitely stand all over them. We had to have the gc pre-pour the length of our drain line 100’ because the ground was too soft even with 6’ long stakes.

This is same thing bill,has to go into oil water separator and yes it is going to be a nightmare with this,an architect and mechanical engineer have drawn this crap up so load requirements should be taken care of,the drains are center of the doors so these shouldn’t be drove over but you never know about volunteer firefighters,some are not the sharpest stick in the bunch,these are the josam 200 sloped drains with a 6 inch outlet going into a 4” pipe,gonna get eccentric reducers so flow line will stay the same,also we are not putting p-traps on the trench drains,the ows acts as the trap for the drains and if gasoline or anything flammable got into the drains it would float on top of the water in the p-trap and if someone was using a cutting torch or welding it could catch all that crap on fire,how did you keep your drains from floating up in the pour bill???

I’m gonna try my best to have the gc to prepour around and under these drains before the main pour goes down,they may or may not do this,they are a pain in the azz for sure,but I can make more money on this job than I can on 10 houses,also the grates a shrink wrapped with plastic so you are supposed to be able to use the grates with the pour,just remove plastic after concrete is poured

When you think you have them secure enough that they won't float secure them some more because they will
