A lot of people want us to jump through hoops and when we do and want them to do the stuff they are required to do, they just ignore it
Yeah and they all take a walk around the scaffold to look at it before they sign the handover cert as well!
It definitely doesn't help if they haven't got a scaffold background!
Best argument against them is take the belt off and hand it too them and say........you fecking build it then.
and get another job lol!!!! knobs thou den they just use calculations to throw you so you say yeah ok see where your comeing from but you really ante got a clue:laugh: 1980 IF YOU ANTE SURE BEEF IT UP TODAYS SCAFFOLDING HAS GONE STUPID!!!!
make you right tom but these youngsters no the weights stress of scaffold and load bearings where there fresh out of school so the scaffolder gets lost in figures even thou they ante got a clue 2014 am afraid!!! your never win with the spotty brigade:laugh:
Scaffolding historically has been blighted (in my experience)by the implementation of insufficient ties or the wrong ties into the wrong substrate by people who have little training or understanding of their correct use. That sounded quite sensible for me.
takes a lot of design and forethought to erect an immovable temporary structure!:amazed:
We all get shown a tie on our courses and some even do a practicle pull test ( ncc b'ham ), and yes we can insert the correct ties into the correct substrate. Now if the ties are fitted correctly and have been proof tested, what gaurentee have we got the struture will hold the scaffold under the said loadings.
Morning Scaffy
If the scaffold pulls a brick out the building the tie still inserted in the brick....whats at fault ??
The main contractor not giving you confirmation that the building is adequate to take the imposed loadings

But then it would be our fault for not getting it in writing first
I told a h and s manager that we could do the prelim band proof tests but he must ensure that the walls where adequate to sustain the loadings, he in turn told his me this who said I was trying to pass the buck!
If you're in any doubt about the integrity of the building its essential to do preliminary tie testing before a deign is sought or a scaffold is erected. This will give such information as type of tie, tie pattern etc.....If the substrate isn't adequate then another form of stabilisation could be required and a different approach may be needed.
You are correct Dangeruss, most issues in scaffolding are caused by incorrect or inadequate something or the other.
Training was a lot longer and more informative when I started in scaffolding it involved working with talented scaffs as well as not so talented ones and you had to decide which bits were good and which were bad.
Having that knowledge was not what made you a good scaff but choosing to use the right ones did.

If it don't bend it'll break!!

Assuming you have the correct tie in the correct place and it is tested to the correct load then the building is inadequate to withstand the forces imposed upon it by your scaffold in use.
In an earlier comment I refereed to "The Foundation clause" all my quotes and designs go out with both a foundation clause and a clause that relates the the structure being adequate to withstand loads imposed by the scaffold in use. I also have a note whereby the customer is to approve layout prior to any erection on site.
If your quote and or drawings have these notes you have placed the contractual responsibility with the customer.

With the correct notes in your quote and design confirmation can be implied by issuance of an order from your customer

Yes, would have been the correct answer to his statement, you are looking to pass responsibility back to your client for a building about which you know nothing. You are not structural Engineers you are scaffolding contractors.

Nice quote from the book Dangeruss, however tests prelim or otherwise will only test the substrate of the building and not the building.
Consider a concrete cladding panel 6m x 6m fixed to the building in 4 corners with a hilti fixing in the middle.
Your tester will test the anchor as a local test but will not test the panel in a global sense. When tested by applying the load on the panel without being propped locally to the tie you may find the panel could break or become dislodged.

I remember reading an article on something similar. It was about a bridge giving way inside a shopping mall in so far off place. They had a bridge at high level spanning from one side to the other at the top floor. This was supported at either end and had stays from the ceiling to support the middle. The subsequent bridges at lower levels had the same arrangement but where there was no ceiling to support the middles, they hung from the bridge above. All was well until there was a ceremony in the centre and the bridges were full. The high level ceiling supports gave way leading to a vertical domino effect killing loads of people in the process. The same kind of principle with hangers on hangers on hangers.
PS Rob and Gordon said to say hello
Thanks Alan, I don't suppose you fancy publishing your notes and clauses?,:cheesy:
I work with them most days Alan, They still take the p1ss if they can. I met them when they left Cambridge SGB and moved to Northampton. We all worked on the MK theatre together, and kept in touch ever since. Now we all work at a massive food plant together every day. Can you remember Project Dragon fly in Cardiff I worked there for 5 months erecting , I think Alan Tindale was the designer ?
