52. Inside the machine house.
Standing down in roughly the basement floor level, from left to right are the concrete wall to support no 2 front side sole plates, the services tunnel, the area later infilled to floor level between the machines and no 1 machine dryer pit. Shuttering in place for the poured concrete along the backside of no 1. In the roof it appears that the walkway down the centre of the roof is being installed, presumably from the rather precarious planking mounted on outriggers on top of the manual crane bridge. The plank walkways and the length of the outriggers appears to be set to the distance between trusses, essential to be able to manipulate materials into place for the longitudinal gangway in the roof. Other temporary planking is in evidence across the roof trusses. Notably the electric machine house bridge crane has not yet been installed.
