mac the knife

Hello folks. We have doors coming in a few weeks with wheelchair accessible threasholds and I need to pour the base of these in advance. The lads who came to measure the door opening said to measure back 70mm from the outer leaf of cavity (100mm) and to pour the base from that out, with insulation put in behind it. Any idea where I can get an exact detail of that? Can supply a photo of the door openings if needed. Cheers

just jumping in here. would anyone have a detail for how to the base of a door with wheelchair accessible saddle? thanks

explain that to me please sheets cut above and below the window? or sheets cut and only running down as far as the end of the roof window frame on either side, leaving the full bottom flashing showing or another solution thanks

thanks. I removed photo as I think the roofer frequents this forum

Have someone installing a corrugated roof and now comes the hard bit, with velux windows to be installed. after explaining numerous times that only a nibbler could be used to do the cutting he went at it with a circular grinder and a 'special disc' he got. anyway, this is the end product. We had a disagreement. He complained about the quality of the cladding numerous times even though it is widely used on houses and domestic buildings. Anyway, he left taking all tools with him Any pointers or suggestions would be welcome We can move that sheet one rise to the right as we were going for a double overlap These are long continuous sheets. How do I get the flashing in under the sheet
