Although this initially seemed to be a relatively straight forward temporary roof, it quickly became clear that there this was a lot more complex than the initial preliminary scaffold design would suggest. This compounded with restricted access meant that LTC and LEAN Projects needed to work closely together. The beamed section and basement to the north elevation meant that this was a complex design, specifically relating to the loads imposed on the existing ground.

Complications.
• Design brief changed significantly to ensure that the load was not transferred on to the existing basement and to allow the new extension to be constructed with the temporary roof in place (bridging section).
• Scaffold loads – the structural engineer had to design mass concrete foundations to take the tower loads to the north and west elevations.
• Existing tree (TPO’s) – LEAN Projects had to apply for planning approval to enable the tree canopy to be reduced for the scaffold gantry to be erected safely.
