When does plumber first fix

[Mgrant]

On a building with modern engineered joist that you knock out. When do you first fix usually after the floor and all stud walls have gone up?

 

[lame plumber]

preferably before the plasterers arrive and cover things up or the chippies board the floors

 

[gasmanrob]

Yeah then you drop your rad tails in the stud work, turn your domestics up in place for bathrooms. Then sparks do there bit then chippies add noggins for rads, dry liners in, mist coat, then free for all on second fix and finals

Thanks got one to start with no floor down upstairs or stud work yet. But work want me to start it explained there wasnt much can do yet.

I like to have the floors down, studwork in and boarded on one side.

Suppose all I can do is get the pipes some were close to were I think the stud walls go up.

yep,after the 1st floor is down and stud work is up. sometimes you'l have one side boarded.
PM me if you want the measurements we use for tail, rad heights etc.

The knock out holes on the engineering joist look a fair bit out of alignment has anyone had this before? Also can you knock the pre made holes out anywhere on the run?

 

[gasmanrob]

Knock out only ever line up for sparks and thier flexible cables. Better off to drill the plot out

 

[Mgrant]

Can you drill these joists ?

Check the MI's.

 

[Mgrant]

Should the site have these?

 

[Ch4 plumbing]

Yep every site I've worked on the site agent has a copy, if not then wait for confirmation but as a start do NOT drill/notch the top or bottom part, sounds obvious but some think it's okay!!

 

[Mgrant]

Thanks.

Is it copper or plastic being used?

If it's copper you need to be before the floors and stud work go in find out the sizes of rooms then bring pipes up where needed, if it's plastic then after floor and stud work.
