Started a new job, it is to put up ceilings, including fitting a sky tunnel a kind of skylight on a flexy pipe fitted to a round window in the ceiling and do the dot n dab to the walls and tape and joint the walls. The ceilings are skimmed by others. The sub floor is in and I have to do the dabbing before the floor insulation and screed go in. I have been told by the manager to put concrete blocks lead down with planks on top to support the boards. oh well they know whats right just plod on after its only another job, something else to pay the bills.
