in these pictures i am building a pillar to support the top of the house as we punched holes through the up stairs walls of the house sild box lintels through the holes and used acrose to hold up the walls so we could knock down the downstairs walls whilst leaving the up stairs untouched. also we put in 4 RSJ's to support the top of the house the corners of these rested on the pillar. the pillar was 9 course high and had 3 pad stones on top of it to support the steel beams. i had to keep a close eye on the gauge to make sure that the pillar and the pad stones fitted underneath tightly. we also packed the pillar with slate underneath the steels to ensure it was a tight fit. Also i had to keep it very plumb so it would set pefectly underneath where the RSJ's met as the RSJ's were bloted together.
