First fix and UFH

[Buxus]

Apologies if this has been covered before. Have I made extra work for the plumbers by fitting the first floor ufh (Ambiente ambiplate) before the first fix?

The joist depth is 200mm, I've insulated under the plates with 75mm rockwool. The builder also layed the floor and fitted the stud walls between the bathroom and ensuite. After one of the plumbers drilled through the ufh pipe, the boss has blamed it on the ufh being hidden by the insulation and asked me to remove it so they don't, 'catch anymore pipes'. Not a big deal but surely they could just move it around.

Is this order of works unusual? They're saying they normally first fix on joists before the floor goes down but didn't say anything at the earlier on site meetings. I've already had to compromise and have it all in speedfit instead of copper.

Floor should have been done last.

Difficult to get pipes in the right place without walls though?

 

[Dan Robinson]

Not sure how that affects putting ufh in last?

UFH passing underneath stud walls!
Sounds like another case of getting a camel when a horse was called for

Because the stud walls are built off the floor.

And that is not how you plan and run UFH!

No ufh under walls. Bathroom and shower room are separate zones designed by ambiente.

Then you have befuddled me with your description! How about a sketched plan of the install/ layout?

No schit sherlock.

Right... think I've got the picture now.
All pipes and electrics 'should' have been run, clipped, lagged etc, before UFH to emerge 'roughly where walls were to be built - plans and dimensions important here.

However, that's now a moot point.
If this is a matter of your plumbers having to do extra work than they priced for, then it's a matter of cost for them to adapt and overcome or time for you to give them a clear view of what they're up against. There's never enough collaboration between contractors on jobs and it seems it will stay that way... unless you use one that has a well-put-together team.

Many thanks for the info, so I definitely put the cart before the horse and made things more difficult, however, most of the pipes have been run without too much head scratching. The build was otherwise going really well so I was more annoyed that I messed up.

Better to get design drawings for both and avoid each others pipe routes
