We believe this would greatly reduce the possibility of total collapse of the structure in
a major earthquake although damage to the structure might occur. We estimate this
work to cost in the $50,000 to $75,000 range.

7.0  NON-STRUCTORAL ELEMENTS

We have not reviewed non-structural elements in this report. We would point out that
injuries and loss of life have occurred more frequently in earthquakes due to falling
non-structural objects than due to structural collapse. Therefore, architectural items
such as ceilings, light fixtures, heavy shelving, etc., should be braced and supported.
In addition mechanical and electrical equipment such as transformers, heating and
cooling equipment, electrical and mechanical piping, switch gear and cabinets should
be prevented from tipping over in an earthquake. These and other equipment iterns
should be considered in a major retrofit.

8.0 SUMMARY

The present structure does not meet the seismic requirements of the NBC 1990 code.
The drawings lack information regarding the floor and roof diaphragms and their
connections which appear to be greatly inadequate based on present requirements.

A complete upgrade of the structure to meet the requirements of NBC 1990 is
estimated to cost in the order of $75,000 to $125,000. This estimate is preliminary
and can be finalized only when drawings are completed and further information as
indicated above is obtained. | |

A partial upgrade might be more cost effective at an estimated structural cost in the
order of $50,000 to $75,000. This partial upgrade would greatly reduce the possibility
wes of complete collapse of the building in a major earthquake, although damage is
ta? probable.
