You must be some sort of prick to post that !
Straight forward roofing scaffold, roofing company needs to load it with roof tiles and the main contractor wants to see on paper the scaffold format for a heavy duty scaffold, Main contractor and roofer have worked out that a general purpose design and loading capabilities at 2.00 kn/m2 are not enough. Can't erect l/bays or similar hence they want me to up it to heavy duty and provide details of standard spacings etc. Know how to do it, just need to show it.
