Facts: |
|
This building built in the early 70's would require fire protection to be sprayed on over the entire 3 wood gym floors causing loss of use the facilities for practices and PE classes. Damage to the wood floors is a risk.
The cost of sprinkling the entire building is very high and adding potentially six figure cost to have the fire proofing completed is not justifiable considering the added protection provided by the sprinkler system.
