    Over here in Quebec, there are three types of people: registered professionals who are licensed by the RBQ (Regie du Batiment du Quebec) and can only work in the trade they're licensed in (i.e. a plumber won't do electrics etc.); there are professionals who are not licensed (I guess the equivalent of a man with a van) and then there are amateurs. In the first two cases, you pay some money to do work which you either cannot do or do not have the time to do. In the case of the contractors licensed by the RBQ, if something goes wrong, you have recourse. In the case of the unlicensed contractors you have recourse through the courts, but this often doesn't give you anything more than a pyrrhic victory.

    Now onto the amateurs. Some amateurs are good and know all the applicable building codes for the jobs they're working on - the only problem is that some of the codes are not available for free, though public libraries are a good source. The main problem being an amateur, is that you often don't know what you don't know. It is this ignorance that is the real danger. A licensed professional will know what they need to know whereas an unlicensed one or an amateur may not. As is often the case in life, you usually get what you pay for.

    At the end of the day, often the main difference between a professional and an amateur is that the former can complete the job at hand in much less time than the amateur. A good professional, though, will often work without any payment up front - at least, that's been the experience I've had with the licensed professionals I've employed on my projects. The more money a professional demands up-front, the more wary I'd be of their capabilities.

    As I understand it - FiT is designed to increase demand for solar PV as a mechanism to increase the size of the sector and competition in it, thereby reducing the cost of solar PV, and increasing demand - a virtuous circle. It is essentially an attempt at "pump-priming" the industry.

    I therefore don't really understand the gripes from those who have a) already installed solar PV or b) want to DIY. Existing solar PV haven't done, and DIY installations won't do, the needed capacity building in the solar PV industry (manufacturing and installation). And if they had and would, then the FiT would be unnecessary.

    I guess the gripe re. Pv FIT , is those of us capable of fitting the kit on our own homes and on the homes of our regular clients , would like to get their hands of some of the generous funding , without lining the pockets of profiteers and trade bodies inaffective at quality control.

    If we had effective policing of building regs. I'd agree with Tonys points ,we dont though. When it comes to smaller domestic works they are only interested in you if you go to them and say , "Hi i'd like to give you some money for you to give me a bit of paper to show my works up to standard".
    In some cases you then have explain to them what it is they're suppose to be checking for.
    If you just crack on with the work , they will never be any wiser.

    Self certifying trade bodies also have problems , good honest worker will do a good job . Its very easy for cowboys to use this system to do poor work on ever job other than the one they choose to be inspected.

    I'd like to see Building controls take on all these various certifying rolls as independent inspectors working with the building industry , for a fee , to educate on and improve standards
    Also they need to be given the power to come down hard on those how do not comply.

    Why would you expect them to be well versed James - again I would say it's the duty of the client and his advisors to ensure the compliance of the project with Building Regulations - ie the duty is to demonstrate the compliance rather than for BCO to approve

    barney how can you pass judgement on anything without knowledge. That's suggesting that BCOs don't need to know much about anything, Doesn't that make them amateurs.
    • CommentAuthorbarney
    • CommentTimeOct 5th 2010
     
    Do you expect the BCO to be a structural engineer or an electrical engineer - they simply need to have confidence that the submitted design appears to comply - the need for it to comply still rests with the design team in my opinion.

    For sure many believe that if the BCO is happy then all is well - not true I'm afraid

    Then if the design team are all professionals, architects,structural engineers,electricians, et al each with their own professional body, why have the uninformed BCO at all. They could self certify and do away with a whole raft of expense and buearocracy. That is reducing the BCO role to a rubber stamp, and an ill informed one at that. No, in my book they have to work as a team where each has a more in depth working knowlege of two or three main subjects plus a overall more generalised knowlege. I can't see it any othe way.

    Well that's actually the way that building control is heading - eventually most aspects will be self certified by "competent persons" and BC will revert to simply being a repository for all the relevant statements generated by the client or his advisors.

    I suspect BCO will then revert to a policing role

    This IS the Irish system - Professionals certify compliance with B Regs with the exception of Part B - Fire .
    One must make a detailed application ( drawings , calculations and written report ) for a Fire Safety Certificate and coming soon with respect to Part M - a Disability Access Certificate .

    Local Authorities do some spot checking . Occasionally a client will be asked to provide evidence that they are building in compliance . The analogy with traffic cops is apt . You may be stopped and checked quite a lot for a period and then not for longer periods .

    Lately a lot of them are requiring that DEAP ( SAP ) calcs are provided at Planning Permission application stage to demonstrate that the design is capable of complying with Part L . This is somewhat controversail some beliving that panning and Building control matters ought to be "policed" separately - I don't agree actually . But there is no Building Control Approval application per se as it exists in England and Wales ( are as existed when I last worked there in 1995 )

    In practice the issue of b regs compliance is "enforced" when Certificates of Compliance ( .... which may ONLY be provided by professional ) are required to be furnished as part of the conveyancing process .

    The DIYer often comes a cropper then if s/he can't furnish certs

    For DIYers, here's a remarkable website: http://www.solarpowerahouse.com/
    It describes how to do DIY solar pv - including fabricating your own modules.

    American, so does not address the FIT issue, but there's a lot of useful information, useful even if you are buying a professional system.

    Posted By: owlmanthe numbers of DIYers doing the more complex stuff is very small and it's better to give genuine help than have it done secretively
    If that approach works for cannabis users ...

    The future will undoubtedly allow and encourage the great wells of energy and creativity that DIY contains. Or if it doesn't, that's another way we're doomed. DIY is the only way when you're colonising a 'new' outback, with plenty of space for everybody (apart from the natives). A bit later on, when you have a crowded and litigious megaloplis to show for it, then resort is made to the nanny state, seemingly 'safe' but in fact just an expression of general decline of human spirit due to the neuroses of biological overcrowding.

    This is the main reason for popular suspicion of the EC - growing 'rational' regulation vs good old British pragmatism and tradition is blamed on the EC rather than an inevitable consequence of overcrowding and over-speeded lifestyle designed to make us buy stuff.

    There's been plenty of work aimed at solving this conundrum for the better - from Ivan Illich onward (and before). It's something that both liberals and self-reliant republicans could agree on - making empowerment of individual resourcefulness a priority, even in an urban society. That's exact opposite of what we have now, and all the urban despair and disconnected behaviour that results. It's a major plank of Transition Towns, by implication at least.

    Excellent link, BV, and wholly in the spirit of overcoming the cost barriers to alternative energy production. One of the biggest element in that cost is having to "prove" compliance. The indications are that such proof will have to involve professionals at every stage, if the provision of an alternative energy source in the your home becomes a planning condition, either as part of a new build or a retro fitting. But why?

    PV fitting companies aren't all in it because they give a monkey's about the environment, and even those that do probably have a particular standard of living as one of their aspirations!

    Christ, I remember going to CAT when it was still just emerging from a hole in the ground, the spirit driving the place one of can-do-effing-must-do. The occasional slide-rule, but generally one of suck-it-and-see and pass on info on what worked. Seems that spirit now survives only in the land of the free. As they say on that site linked to by Bif...

    "But what is really costing so much to solar power your home with traditional solar installation?

    For one, the labor cost to solar power your home is high. Traditional solar installation requires technicians that must mount solar panels on your roof and they don't work for minimum wage.

    Also, solar panels themselves are expensive. To accommodate the needs of an average sized house, you would need to use multiple solar panels which can add up to a lot of money if you're buying them at retail.

    If you're having a professional install your solar energy system for you, get ready to pay huge mark ups on everything from the solar panels, to all other equipment, to solar installation charges.

    As a result of all these factors, you end up spending a lot of "extra" money (to the solar installer) just to try to save some money (on your utility bills)."

    True; If the meter says that the thing is working and power is being produced, that's compliance. As far as I can see the only bit that requires professional experise is grid connection and a bit of internal wiring.

    I think there must be a middle ground that doesn't stifle creativity and enterprise and freedom and yet at the same time gives some degree of accountability for government largesse. The problem is we're a nation of "jobsworth's" we love inventing rules and regulations and an army of enforcers. Most of the green energy initiatives, with their system of hoops to jump through only serve to line the pockets of the middlemen who have to pay to belong to the appropriate "professional" body, then they get a stranglehold on installation, and therefore pass on the costs. In the end the punter pays, more than is necessary in order to get the government handout. it's the law of unintended consequence. I can't believe the initiators intend it that way, or there again maybe they do?

    May I comment from the basis of working within a Local authority & through Architects.
    A complete non-corrolation beteen the planned works/specifications and the actual installed works.
    Repeatedly seen with my own eyes.
    Self levelling concrete.......erm "slump test" anyone.
    Sewers diverted using 4 No 90 deg elbows under a floor to avoid a wall, try rodding that one.
    Floor tiles "boast"
    Walls cracking
    Floors not level
    Copings on a roof on a gable end wall NOT secures simply sitting under their own weigh until one blew off
    etc
    etc
    etc
    etc
    Oh yes & Plumbing not correctly installed.
    And dont mention the play area construction
    and this was all "professional" work
    scheesh

    Not an uncommon problem - although perhaps more reflective on the fact that a client often appoints on a lowest cost first basis (for both his professional advisors and his contractors) and relies on a contract rather than appropriate supervision to get the job done.

    Barney, the 'spirit' that inspired CAT had to do with encouraging people to make improvements in their own lives. If they worked on a neighbour's roof it was because the neighbour had previously worked with them on theirs as part of a communal project. The spirit of CAT at that time was agrarian/egalitarian. Sustainability was the watchword, and having to call out a highly paid engineer to sort a problem and then sign a bit of paper didn't quite fit into that scheme of things.

    Given the commitment of those concerned with environmental issues at that time and the conviction needed to sustain that commitment in the face of a growing consumerism that treated all forms of energy as an infinite resource, there weren't many numpties around. Unless you counted the woman running the restaurant at CAT, whose sole conviction seemed to be that anyone who didn't want to eat nut roast, or a variation, at every meal wasn't worthy of her time. That a few of us took ourself off to the local pub for a bacon sarnie brought on a fit of near apoplexy and a stony stare when next we entered her establishment.
