The twin towers at UCLA's Josiah Royce Hall sustained major damage during the Northridge earthquake. Consequently seismic retrofitting was required and all damaged brick and terracotta pieces had to be removed and replaced. Yet Royce's historical significance to the campus required that the original building material be used.
Mortar joints were saw-cut by hand so that larger units could be removed as one piece along with removal of all substrate. Severely damaged bricks were replaced by pieces that matched (in color and size) according to the architect's specifications.
By using this method, J.B. McGalliard ensured that approximately 95 per cent of the original bricks and terracotta was salvaged; architectural specifications required 70 per cent to be salvaged. |
