So this is where the process is broken !!! Someone on here did their own design - and I've done a lot of tweaks to ours too - so I doubt there is any SE or architect that would be involved on either of those builds.
My SE has purely done steel calcs - the rest of the "structural" design is standard elements as per the Building Regulations or robust details etc and will be signed off by the BCO. So how do the HSE want to work with that one..??
The other query I have is how HSE are going to track these builds with the "estimate vs reality" calculations on labour. For example, according to the QS estimate for my build I have an estimated 22 week duration with 2213.45 hours (!!!!!) effort involved. Based on a 6.5hr working day, that equates to 340 man days effort, or an average of a little over 3 people per day on site. None of those figures will trigger the HSE F10 at the start of the project and its within a good margin before it could (at 500md / 20+ for 30 days)
So in completing the paperwork, as it doesn't need filing then no-one is checking to see if there is a PD and the PC is me with subs. In the end we will get a building that is built to someone elses initial design, with SE calcs for bits, and a BCO signing off that it meets stat regs..! Oh, and a warranty by another company just for good measure..!
