Of particular pride is last minute intervention to eliminate some temporary works that were threatening cancellation of an Arthur Andersen international convention, a major source of revenue. Wrong computer analysis had predicted collapse and the need for extravagant temporary works but these were easily shown unnecessary by experienced 3D analysis.

The buildings are now being restored to create workshops, offices and a community café.
