Posted By Ian Bruce I would be very interested to hear other colleagues views on an issue I am currently dealing with: A scaffold structure was erected a few years ago within a Community Centre, the structure supports an artifical ski slope used for tobogganing activities. The structure is inside a building and is not exposed to the weather at all. Risk assessments exist for the activity and in general it is in good order and well maintained; I have no real issues around the activity, it is the scaffold that concerns me. I am inclined to say that the structure be inspected for integrity on a regular basis - weekly, as you would on a construction site, by a competent person. On the other hand, the need to inspect and the frequency of such inspections could perhaps be determined by risk assessment. This is the direction I'm tending towards at the moment. Could any one provide me with guidance on what would determine competence for this inspection, bearing in mind the nature of the structure and it's environment? Thanks in advance.

Posted By Chris Turner Ian, I feel that you are right in going down the route of inspection, the frequency of which would be determined by risk assessment. I also feel that the best people to inspect it are the ones that built it, that is sthe norm in scaffold erection.

Posted By Gerry Marchant 1) Is the structure a working platform or just for support? 2) The current Construction Regs state it should be formally inspected (written) every seven days. 3) Do you want to pay an organisation to do this or do you want to do it yourself? The CITB run specific courses to inspect scaffs. If it is designed thenthey aslo run courses for this also. Speak with your local authority or HSE who will give you guidance. All the best with it though!

Posted By Martin Daly This scaffold is not on a building site so is not covered by CDM. The reason scaffolding has to be checked every week on a building site is that it is continusly being changed adapted etc. And it is exposed to the wheather. Your scaffolding is inside and never adapted. You have only 2 problems that I can see vibration and corrosion. The scaffold fittings should be checked to make sure they stay tight And the tube checked for rust. Yours Martin Daly

Posted By Robert K Lewis Martin CDM is not relevant here as it would be the CHSW Regs that would apply in construction. On the general point why on earth was a scaffold system chosen in the first place? They are intended as temporary structures and as such are susceptible to deterioration at a faster rate than a permanent frame. The longer it is up the more likely it is to start to fail without regular checks and maintenance. The problem is ultimately the vulnerability to vandal damage especially with regard to the couplers. If it fails you will have to justify to somebody why it was not inspected on a regular basis. Fairground rides, I seem to remember are checked at least daily. The CHSW Regs provide a requirement of 7 days max, so you will need to show a full risk assessment by a competent person for anything less onerous. This should have a written scheme of examination attached. Bob

Posted By Arran Linton - Smith If this scaffolding structure falls outside the scope of BS 5973 which I suspect it does, there should be some designer drawings for it together with design calculations. The inspection of the structure should be undertaken against the designer’s drawing and not the scope of BS 5973, therefore you do not necessarily need someone who has done a two day type scaffolding training course to undertake the regular inspections, however I would use a specialist scaffolding inspector to periodically check the integrity of the structure. My view is that it is best practice if the structure is check daily before use with a more thorough inspection at a period which someone will need to determine. If the structure has not been originally designed by a specialist scaffolding design engineer (and it falls outside the scope of BS 5973), then it should not be used until it has been inspected and modified to their specification. Let them advise you on the method and period of inspection.

Posted By Ian Bruce Many thanks to all who have responded. In answer to a few queries raised within the responses: There are no design drawings or specifications. The structure has been in place for 12 years, the individual concerned who organised its construction is now employed elsewhere, all others who use the area are members of a voluntary organisation and have no records other than their own risk assessments, safe systems etc. I won't bore you with further scary details about competence to supervise, training in leading activities, sufficiency of risk assessment etc!!! There is no hand over certification or post construction/pre-use certification of inspection, if there ever was one, it's been lost in the sands of time! Why scaffold? I'v no idea! Probably someone had a job lot hanging around! I have recommended that all activity cease on the structure until all my areas of concern are addressed. I shall be insisting that the structure is inspected by a suitably trained (CITB?) competent person before it is put back into use. I'm hoping that this individual, as yet unidentified, will assist in formulation of a risk assessment detailing further inspection routines. Thank you all once again. What a great forum this is.

Posted By Arran Linton - Smith Ian, I cannot emphasise enough the importance of having this scaffolding structure designed. If as I suspect the structure falls outside the scope of BS 5973. No matter how competent you’re (suitably trained) individual is, without a design, there is no specification which he can safely inspect this scaffolding against. If this scaffolding collapsed, the implication on not having a design would be immense.

Posted By Geoff Burt Can you design in retrospect?

Posted By Arran Linton - Smith Geoff, In these circumstances a scaffolding designer can assess a structure similar to this after it was constructed. The designer does not necessarily have to draw the structure, but if undertakes design calculations and specifies the scope that the structure may be safely used then in these circumstances this may be sufficient. This is a good NEBOSH diploma question.

Posted By Keith Archer. Arran, Good point about this query being a diploma question. Just hope that everything is sorted out in this instance and prevents it from being the potential case study question. Keith

Posted By Robert K Lewis With the outlined history of this structure I suspect that no designer is going to put their neck out too far. The uncomfortable truth is that it may well need dismantling and re-erection to a designed scheme. Bob

Posted By Ian Bruce I would like to thank all those that responded to my request. Just to keep you informed, the structure is now closed. I have instructed the organisation to arrange for inspection by a scaffold designer and to prepare an inspection routine based upon the findings of that inspection. As the structure is within a City Council property, the report has gone to the "land lord" who is considering permanent closure and removal of the structure as the prefferred route. Thanks again.
