week 12. completed scaffolding this week. once the wall frames are in position, we set up the scaffolding to provide a safe working platform all around house 124 matching the adjacent house 122. metal tubes are used as vertical standards and horizontal transoms, rails and braces. sitting on steel sole plates and timber sole boards, we set up the transoms, handrails, mid rails, diagonal braces as well as timber planks for the platform and toeboards and a ramp with cleats to provide easy access. scaffold must be triangulated for rigidity. planks must overlap transoms and be secured.
