So you think that the structural calculations, the building work, the detailing, all the activities needed to ensure (and show in advance) compliance with the requirements for structural safety, fire safety, resistance to contaminants and moisture, resistance to sound, ventilation, sanitation, drainage and waste disposal (if applicable), heat producing appliances, conservation of fuel and power, electrical safety, workmanship and materials are no more complex than replacing brake pads?how easy is it to replace a set of brake pads? how easy is it for a qualified mechanic?
it is pee easy and if you dont know how to change your pads or overhaul your braking system then you can pick it all up from a manual or from some instructions online.
What about the entire roof collapsing? What about structural damage to someone elses property?i would guess that brake failure have the potential to be considerably more dangerous than a floor joist falling out of place.
Is that all he needs to be able to do to calculate, for example, what size steels are needed?can the OP use a measure tape, a saw and a screw driver?
I'm not.then lets not assume that he is an idiot
I actually said I wasn't assuming that.
I might start assuming that you are though, if you fail to read properly.
You do need to be just as competent as a professional structural engineer, for example.and that you dont need to be a self righteous 'learned' "expert"(?) to convert a loft or fix your brakes.
Runs in paintwork, bubbles in wallpaper and the pattern not matching, lumpy plaster, wonky shelves, doors that don't quite fit, a lawn full of dips and crests, none of these will kill you. A dodgy structure might - there is no room for lesser standards of ability.
