Unfortunately we are having to remove a section of building and replace (I wouldn't, and think they can be fixed, but have not prevailed, mostly because we can't get builders or designers to do tricky stuff.) So 40 tied trusses have to come down. The wood is good apart from a few ends, and can be reused for roof or inner walls. Any tips on how to get 50 year old twist nail connections undone? Either up in the air if the demo people will consider it, or on the ground once chain-sawn apart. 2 twist nails per joint, right through 2 x 45mm, and 30mm extra length bent back. For the interest of anyone....interested. I calculated the design using the Scottish Government 'how to do it' guidance for 'non-Engineers'. Tied trusses with ridge plates, and some shear walls. The local Engineer we are now required to engage is specifying Ridge beams (big) and props, and no ties: I guess because they never have to use the simpler, standard method. Then another ridge beam and some steel beams to support the ridge beam!
