tray work

[amckay]

I've started subbing on a site on Monday (the site has been active since July) and today I had to earth containment trays, putting copper bars over joints etc. Anyway its a 10 story building and it has a riser for cabling. However the trays in the riser are not continuous its just a 1.5m section thrown against the wall with around a 18 inch gap in between floors. So I'm linking them together by crimping 16mm2 and using 1 inch long bolts (they supplied them). The way i have bolted them is with the threaded shaft protruding the top of the tray where the cable lies. My supervisor rekons niceic will "fail" it as the cable sheeth could tear against it during installation.

Personally instead of swapping the bolts around, I rekon a bit of heat shrink will do the trick

Am I wrong?
Bearing in mind this is the first time I've done commercial as I've mainly done pat and domestics

Specially when you get a clout round the head when you do make a mistake. Kind of drives the lesson home properly

I know of a spark and his apprentice were working in a school one day, (i actually know both fellas seperately, both quite cocky) the spark was showing off his authority in front of other tradesmen trying to belittle the apprentice one thing led to another both boys had to be pulled off each other, chased off site and had to drive back to their main office and explain why they were sent home and why the company lost that maintenance contract, needless to say both boys were fired on the spot

It's all too ruddy flimsy whatever 'duty' it is supposed to be!
