Posted By patrick carr I recently had to go to a new-build construction site, in my role as a scaffolder. I have used ladder beams before on independent scaffolds on numerous occasions, even inserting a 4 or 6 mtr ladder/mod-beam, on a newbuild putlog scaffold, to flyover low-level roofs etc,however i have always used them in pairs,the inside beam acting as a bridle,and plan braced back to the ledger. On the site in question, there was a block of 4 pairs of semi-detached houses in a row, all the scaffold was erected as one plot. However on the rear of the aforementioned plots was, 4 pairs of low-level sun-rooms/family rooms. the contracts manager wanted all the roof-works-roof tiling done at the same time. This plot had a string of ladder beams, the full length of the rear, approx 8x6mtr ladder-beams,interspaced with 3 stds,in-between each low-level roof on the 3rd lift, to enable the pitching and tiling of the low-level roofs. My concerns are, that the ladder-beams are being used as a ledger, with a bridle being used as a alternate beam,rakered back to the bottom of the beam. My understanding is all bridging beams should be used in conjunction with one another, and appropiately braced as such. There are also issues with, workers working under a active working platform above, I.E. risk of falling materials,etc.

Posted By RP Should be supported on Standards and connected using sleeve couplers. Where there is a risk of loading a knee brace can also be used. Its all about design for loading, as for working underneath, easy to stop whilst overhead work is being carried out.

Posted By patrick carr thanks RP with all due respect, i am after the legality of carrying out this practice, we use sleeves for all aspects of our work. I am a recent member of IOSH, and i am a TUC H&S rep,just completed my access cert in ohas,iv'e been a scaffolder for 30 year,and it's the first time iv'e encountered this practice, i am very interested in the forums views, before i contact NASC, for advice, to back up my concerns. regards paddy

Posted By RP Whilst there are no specific 'regulations/law' pertaining to scaffolding, we are using the EN and BS guidance, such as new BS EN 12811. Also TG20- 2005 currently being revised, from the NASC to bring it into line with 12811. Personally I prefer the old BS 5973, it was more detailed in designing scaffolds, and I still use it but amend things like double guardrails, etc.

Posted By Garry Adams Hi Paddy, Salutations Brother Scaffolder, howz it hangin ?. Just read your post with interest, I concur with your observations, My advice would be to contact both the Health and Safety and the Technical Committees of NASC and express your concerns. Is the Scaffolding Mob you work for a member of NASC ?. Easy way to combat workers breaching the Hazard tape / Barrier, drop a fitting on their head , then ask them to wipe the blood of and send it back up, perhaps unauthordox but it works eh. Fraternal regards, Garry...

Posted By patrick carr Hi Thanks very much, to RP, and GARRY (or is it Gerry, as your so often called on here), you have raised some very good points. Our scaffolders, are employed by the company concerned here, which is quite rare in this day and age. over some time iv,e contacted the NASC, several times, regarding specific information, which i must say has been absolutely spot on the mark,their replys. I think what might happen in this matter is, if it,s out of the ordinary, you will need technical assistance and a design. regards paddy. PS GARRY tried the drop the fitting on the head scenario, couple of times, but the lads wouldn't pass them back up.

Posted By Garry Adams Paddy Nae bother just glad to respond to questions regarding Concerns within the Scaffolding Fraternity. Like you Paddy, I have decades of experience in our game...we have seen many changes eh ?, H.S.Q.E. issues have come to the fore more than ever. The development and implication of control measures both Mechanical and documental have modernised our Industry, indeed it has evolved considerably since I started with S.G.B. in 1972. I often try to recruit the young Scaffs into the World of H.S.Q.E., however it is seasoned veterans like us that must lead by example. The collaboration of Brother Scaffs is beneficial for all concerned...net working and the exchange of information is vital for personal development and the evolutionary changes need to haul the Scaffolding Industry into the 21 st Century. The Company concerned should have In-House induction and training programmes that will maintain the Professional standards expected of a Modern day Construction Company which has its own Scaffolding Operations Department. Perhaps this is your opportunity for you to request an informal meeting with the Management whereby you could combine your H&S knowledge ( backed by your peer group members, collaborators,) and your Scaffolding Experience. They would be short sighted if they decline your offer. In regard to Technical assistance, no doubt you can remember when the Scaffoler had to sus out the job in the old days, now there is a team of office waller that do the same job i.e. sussing the job out is now (a pre-job analysis) (safe system of work)(method statement) ect. ect... gone are the days when a job was sketched on the back of a fag packet in the pub eh...if a Structure is not a off the shelf job it is now deemed a bespoke structure and a Working Drawing must be generated. Ye my names Garry...Its just that Gerry is still in synonymous with with my Irish cousins, My email is ...garryadams@hotmail.co.uk dont hesitate to contact me for an exchange of advice and support. Fraternal regards, Garry...

Posted By Robert K Lewis The scenario you describe is not one of the standard solutions of TG20 and as such must have a design to back it up. No design - scaffold does not comply. I am always pretty black and white on these things as as if you give a millimetre the next time they will take a couple of kilometres, in pc metric parlance!! As Garry would probably say - don't forget the torque. I would add don't forget the ties either. This really sounds like a made up on the job design based on "My experience". Just like the Contract manager at Daveyhulme. - Leave them out they are not necessary!! I do wince at some of the solutions I have seen. Bob
