    Firm I do work for has been told that in order to comply with London Underground contract requirements they must get registered with ‘fors’ and drivers must have cpc.
    This is not for over 3.5t vehicles but for personal vehicles and light pickup trucks.
    Obviously fors registration want a few grand.
    All the time it’s about money schemes

    Isn't it odd how the people behind these schemes are pals of the people in power?
    It's almost medieval.

    Recently there have been issues with welding rebar from the far east.
    Turns out they added boron to the steel so they could call it low alloy steel and this was causing cracking if the steel was welded. (in pile cages for example)

    We can all say this is just red tape and big government but Grenfell should remind us what happens when there is a bonfire of the regulations.

    Hot news topic right now is that Crossrail has been put back to 2021.
    I know someone involved at a high-ish level, he is desperately seeking employment elsewhere before the wheels come off. He divulged that right now one person is actually working and three people are needed to observe, document, administer and oversee that one person. Say what you will about "safety" and regulations but in every way that is excessive.

    It seems most things in life have been looked at in depth since creation of the blame culture for some parasite to latch on to your money.

    Thought the rebar welding is odd given if they are made onsite they are wire tied, isn't it only welded to aid moving it?

    Its a bit like Lord Pilkington, he couldn't possibly of had a hand in some of the legislation that would benefit glass manufacturers. We wont side track on to chips in screens and door glass :vsad:

    Almost all CFA (continuous flight auger) pile cages are welded now and most of the big players will not install tied cages, sighting H&S concerns. (There have been incidents where people have been hurt when a bar dropped while they were being joined, or cages have collapsed while lifting)
    On big cages they might need to weld a 12mm spiral bar to a 50 or even 60mm main bar (not commom but happens) and that's not particularly straight forward if you want the same properties in the steel after welding.

    I totally agree with this and it's one of the reasons we are so far behind similar industrial nations in the productivity stakes and why some of our infrastructure is soo expensive.

    Don't get me wrong, I'm all for health and safety, but some of it has got totally out of hand.

    Always assumed it was mild steel

    I have no knowledge of reinforced concrete strength, never interested me.
    But that makes sense given the way mild yeilds.

    I just knew you can get mild rebar never considered it has grades.

    I was involved in replacing corroded rebar sections on a motorway bridge. Full pen with a backing plate with 10018 electrodes

    Doing demolition I hate seeing welded rebar. It usually comes with unexpected surprises and I'd say that 4 of every 5 welded joints break off easily. If you can find a row of them you can tear a whole chunk of slab off with a couple of bends.
