Rubber base may save city hall
|
VANCOUVER - Seismically upgrading Vancouver city hall would be expensive and could change the look of the heritage building, so engineers are considering an innovative way to save it during an earthquake: lifting up the structure and putting a rubber foundation underneath.
The rubber would absorb the vibrations of a large tremor and protect the old building from being too badly damaged, said Garrick Bradshaw, city hall's director of facility design and management.
