I've just had a scaffold erected at my house, solar panels being installed on Friday, and would like a scaffold expert to see a picture of the scaffold and give a view? Anyone willing please pm me and I'll send my email addy then the picture. It's a shame we can't put photos on the forum? Thanks

John, Is that really the scaffold or are you taking the mickey? I'm NOT an expert, but it looks barely OK to me, & I mean BARELY. I would want a competent second opinion, not mine. ;) FS101, Is that roof south facing? What size system are you having installed? Ensure that it is done to BS7671 & the REAL requirements etc. Ensure that the feed in from the inverters is at the origin and is "upstream" from ALL final circuit protective devices. IF you come back to me quickly I can get any info run past some good colleagues of mine to get the proposal validated, if you are paying and you want to ensure you get value for money. IF you want clarification, you know how to get me.

I am not a scaffold expert either but even a cursory glance shows that the toe board is insufficient, the scaffold doesn't appear to be tied to the building and some of the poles don't appear to be protruding far enough through the clamps. The gate doesn't look to be properly fitted and having the thing sat on a few skinny bits of wood across the tiled roof seems insane too me. The first thing the bracing struts would do if things start to move is skid across the concrete and a single diagonal cross brace to my way of thinking is woefully inadequate. As I said I am no expert either but I wouldn't want to be up there. Could they not have hired in a spider lift for the job?

Obviously it is difficult to comment from one angle, but: My observations 1. No baseplates under uprights on roof 2. Sole boards under uprights and rakers are inadequate 3. Toe boards missing 4. Distance between transoms are to far apart, should be 1.2 maximum 5. No end bracing fitted 6. Façade brace too shallow an angle 7. Doubt if the satellite dish can pick up a signal You should ask the contractor for a copy of the scaffolding inspection and also ask if the roof it sits on can support the intended loading. There are better ways of doing this but cheap is cheap until there is damage or loss.

Firstly thank you John for putting the picture on your site and making it available to all. Secondly thanks for the input everyone. The company installing the panels is "XXX" and they provide them absolutely free. They do the install, maintenance and everything for 25 years. What they get out of it is a large government subsidy and the electricity I can't use goes to the Grid and they get the money for that. What I get is Solar panels, free electricity during day times and the panels monitored and repaired when necessary at no cost to myself. There is lot more to it but I won't go on a sales pitch here, suffice to say if anyone wishes to ask me more just pm me. If I refer there is monetary reward to me and to whoever I recommend. The workers are employed by XXX and they install thousands every week, not surprising since they are free. If you all don't mind I might contact the company with your views and see how they react. Paul, Hi, I believe the system will be up to current required standards, they are a reputable company, been on Watch Dog and and the Money Supermarket chap says they are OK. The Sky dish does not receive a signal through the boards but thankfully we have Sky Go and iPads with apple TV so I can still get the footy on Saturday.

FS, OK thankls, putting up photos via my website is OK, done it for others before. Scaffold - I have same concerns as RP and CarlT. Particularly it looks like it is not tied at all to the building??? The uprights spaced too far apart, no baseplates for uprights, no diagonal bracing, no base plates for the rakers and their angle looks too steep, toeboarding incomplete. If a ladder is used to reach the gate I expect it's angle is too low like 50deg?? I can just see the whole thing sliding into the garden and some poor chap will be strangled by your clothes line :o) What does their own inspection checklist say? John

Hello Everybody. Being a Scaffolder to Trade before getting into the Safety Game, the points noted by others are valid, however looking at the structure from the picture - The Scaffold has a few points that need rectified. 1. The standards have been placed onto the Roof - looking at the picture, I do hope the roof can take the height as the Tiles may get smashed or a possible roof collaspe - believe me it does happen. Usually in these cases the Roof could have been bridged with Beams to avoid any dodgy Roof work. 2. Access / Egress - Look at the ladder point where the ladder gate is - it is not thought through by having a ladder positioned at a angle on the roof to gain access. Have a chat with next door on the Right of the picture to see if a ladder could be placed in their garden leading up to the working platform. 3. Look at the Bay size to your left - The bay in question is to large - the maxium for a General Duty Scaffold Bay Size is 8ft - tell the contractor to put in 2 extra standards. 4.A few mentioned Toeboards in the other replys - Ensure that Toeboards are secured Twice by Singles, no matter on what the size of the Board is. 5. A few replies mentioned it is not Tied to the Building - There is no need on this occassion as it has been Rakered to the ground - See the big tubes at each side of the scaffold running at a angle. 6. Also someone mentioned Baseplates - Only on Flat surfaces, not on Roofs. Its easy to sit here and Rip the job apart but remember the Scaffold in question is one of the better ones that are being used and erected on domestic properties that I witness when walking down the street.

Allan, good to get a scaffolder's opinion :o) I mentioned tie-ing because although there are 2 rakers I still think the whole thing could slide side-ways. And aren't the rakers a bit steep, I can also imagine the whole thing siding outwards ?! JohnW

I was thinking they would tie in to the gable end because that's what their safety notice states, they now say that does not usually happen? I also thought they might provide a deeper working platform, fully over the extension, and that would make the ladder angle much better, but who am I? A mere CMIOS who is always concerned that employees can return home from a days work safe and well. I'm sure you all think the same. Many thanks

Hello All John W - I understand your concerns, the Rakers will take the strain, however I am more concerned about the Roof collapsing due the weight - as mentioned before the common method in these types of scenerios is bridgeing with Beams. Scaffolders try to avoid using Ties in this situation due to the damage done on domestic property and also to avoid this further they use the Butting method during the erection, were the transoms are butted into the brickwork. Fire Safety - Please by all means use the comments provided earlier to enfore your msg - remember the access and egress issues that I mentioned as you do not more height and operatives standing on that Roof. Let us all know how it went. Thank You. Allan

Paul, coming from a MEWP hire background I always see things from a "could they use a MEWP?" perspective and as such have no real experience with scaff or in fact with solar pv. Obviously MEWPs are not the answer to every WAH situation but they are probably far more versatile than some people give them credit for. So for my own education I wonder if you would comment on why you believe scaff is better in this instance?

Well here is how it went : email received from the scaffold company at 1553hrs. Hi Mr Burns Thank you for sending the photos in. After looking at the photo's I agree with some of the points made. I'm arranging for a team to come out and make alterations to this job. A team will be with you today. I appreciate you bringing this to our attention. I will also be sending the team on a refresher course (COCS) as this is not the quality of work we expect from out teams. A warning will be given to the team leader as well. Thank you again XXXX I would say this is an excellent result and thank you all for assisting. Pats on the backs all round and have a drink on me this evening. You should all be very proud of yourselves. I'll send another picture to John for tomorrow if that's all right John? What a great forum this is. I laughed out loud when I read the email. That's the scaffolders sorted now for the installation team tomorrow. Watch this space ha ha ha ha.

Carl, I have used MEWP's quite a lot, personally for many jobs, I mean actually as an operator, one of the issues with fitting solar from a MEWP is the knuckle under the bucket preventing the required access close enough to the roof. The obvious access issues, the last MEWP I used was 19t on the road to get the reach, they do tend to have a lot of body centred mass to make them stable. You are handling large sails up on to the roof, the panels, so, the hand rails around the MEWP are restrictive, the requirement for the lanyard restricts your access to the roof from the basket, you can't leave the basket as there is no protection for you. The getting of the equipment from floor to roof with a MEWP would be a lot of operations, noise in a housing/domestic environment from the engine, yes I realise that you can get battery versions which are silent. Transport of the MEWP from site to site, typically a solar install is a single day. The scaff is installed in advance, as here, the installers turn up, do their stuff, then go, then the scaffolders come back and remove. Storing a MEWP @ a private dwelling for a few days, possibly a week or even more would be an issue. Also HSE / Industry guidance is Scaff! ;) etc. etc. Seriously, I am a MEWP fan, I feel safer and prefer working from a MEWP, than I do a ladder, no matter what. I have had a large 4WD Haulotte platform as I say 19t on the road, I can't remember the model, with the boom vertical, no worries at all, felt as safe as I do on the floor, in fact, I actually enjoy working from MEWPs. However, they are not the tool for pitched roof solar PV installs.

Paul, I am not a MEWP expert but can support you here as the access to the rear of my house is very limited. I have a narrow access, less than 1 metre with a "dog leg" type kink that makes it impossible for a MEWP to get in. Just wait 'till you see the latest scaffold, you may be amazed at the difference that two teams from the same company can make? I am aware that the installers actually man handle the heavy panels up a ladder so I will be out of the house when they are at work, after taking a picture of the operating ;-)

Allan, thanks for reply above. Yes I accept that tie-ing physically into domestic brickwork would not please the residents, when I say 'tie-ing to the building' this can include various methods, as you suggested 'butting' scaffolding against brickwork with wood. I've also seen a suitable system where a building with a roof parapet has scaffolding secured going over the parapet (because the walls were to be expertly rendered). On our domestic example here, since they are working on the roof they could have extended scaffold over the top to the other side. If Chris gets some 'after' photos today I'll upload them as before, though that may not be until this evening. JohnW

I don't know you just can't do right for doing wrong? Without the assistance of John the roofers would have had a very dodgy scaffold to work off as I doubt very much if the Scaffold company Director would have reacted the way she did without the comments I passed on to her, gained from this forum, and through the aid of the photograph that John enabled all to see. We were all working together here and had great success. John has a website with the name he has given to it so that one was used for this purpose. I for one appreciate his help and so do the roofers who had a very much safer working platform, after all isn't that something we all strive for? If not you are in the wrong profession.

Certainly got a result there FS! The scaffold is now on a much better footing on the ground (though we can't see it), access to the gate is better, bays look the correct width now, complete toe-boarding. I'm still worried about the weight taken by the tiles though, but overall much safer than before! John

Yes John, I just hope my footy team gets as good a result at Arsenal today. The work was done yesterday in about four hours, solar panels are placed on and secured to long metal strips, (aluminium?) so the load is well spread. The roof timbers were checked out by their surveyor a few weeks ago and he confirmed all OK. The electrics are on a board secured to the underside of the timber in the roof space. The only criticism I would have is the panels were carried up the ladder, thirteen of them, (one at a time), don't know the individual weight but one man seemed to do it no problem. They have a video on their website showing just that. All in all a good result, I have my free solar panels and they get the residual electricity to sell to a Grid. Thanks again John.

Just one house in our street has had panels fitted. Apart from looking ugly (upsetting folks across the road!) neighbour said there might be some issues later as the deal requires you to 'sign up' for a 25-year commitment, the supplier might go bust and the government might changes its policy. John

It is a 25 year deal but hey ho it's free and the company are doing so well and making lots of dosh for themselves so were happy. If you go through life without taking a chance and being suspicious you will never get anything for nothing. Some people actually pay for these. My panels are on the rear side of the roof and it's difficult to see them from my garden. All my neighbours are showing an interest and looking to get them for themselves. No worries. I hear that all new houses with south facing roofs will have solar panels installed from 2016.

Thanks Paul for your comments @17. Yes I can can understand access to a sloping roof is probably not ideal from a MEWP although the knuckle of the boom wouldn't in most cases be a limiting factor as they are generally no lower than the bottom of the basket. Getting the machine into position is an issue although some of the spiderlifts can fit through a standard doorway and still have a 17m working height. Regarding lanyards, do these guys use harnesses and lanyards when on the roof? On balance though I would expect a scaff would be a better option, the reworked version that is. I hope this isn't a one off and they revert to the original setup for their next job.

Irrespective of whether business was generated or not my understanding is that advertising is not permitted on the forum. I mentioned an outfit some years ago and had it pulled by the moderators. Seems a tad inconsistent to me. Seems rather odd also that the scaffold outfit is not to be identified, if it was we could perhaps avoid them. Jon

Jon, I agree that advertising should not be permitted on the forum. The point is I was not advertising my business, I have only posted an image, and there is in effect no direct link to the main website. To find my website proper one has to chop the link or cut and paste to find it, and who would bother when all we are doing is helping out Chris' contractors. The scaffolders have, eventually, shown they can do a proper job so I would not avoid them if they were local to me. John

We should not consider punishing the scaffolders because they have rectified the problem. They sent out another team who modified the structure to a safer model. They are retraining the original team and discliplining the Team Leader. They will be better in future.

I am somewhat surprised at the content of some of the posts. We have a number of "technical" answers, which were useful, but no mention of "management" controls and remedial actions. The end result, scaffold rectified, safe working environment being achieved should be seen as a success. However I would make the following comments. In #15 the scaffolding company response was at the "lowest common denominator", warning, retraining. (Typical answer you get from company's confronted on Watchdog type programmes) One talks of "not punishing the scaffolders" The scaffolding contractor was probably selected from "get three quotes and go for the cheapest" school of contract management. The scaffolders erected a "poor" scaffold because they were allowed to. Supervision allowed a poor scaffold to be erected because it was acceptable practice and management allowed and condoned a poor scaffold to be erected because they probably don't care, as long as the job gets completed and they get payed. Sir Henry Royce (of Rolls Royce) state more than 100 years ago: "The highest standard anyone will work to is the lowest standard that a manager will accept". That was true then, it is still true now. There is a lot for us all to consider in this story.

Rodger, your point on lack of management is very important. In #8 I did ask what the scaffold inspection checklist said..... if such an inspection was documented then it would ask things like 'are the bays correct width', 'are toeboards complete', 'is ladder access safe' etc etc. Ideally a supervisor should document the inspection, and when the inspection is satisfactory then there should be a handover certificate which FS or the contractor should hold on to. And now that the scaffold has been modified there should be a new handover certificate. I don't get involved with 'domestic' scaffold work but I expect this lack of management and documentation is common. John
