The Fire Sprinkler Scope of work consists of adding and revising the fire sprinkler protection to a portion of the building. When the fire sprinkler work is completed, the entire building will have fire sprinklers. The work will begin by adding a new backflow preventer and adding fire sprinklers to the eastern end of three levels. The basement fire protection is apparently existing. However, extensive changes are required to the fire sprinkler system. The existing underground piping is 4". The second floor piping will be tented with insulation to prevent freezing. The attic system will be a dry system. Each level will have a floor control valve per BMC. All sprinklers will be quick response type.

Plan Mod 1 Scope:

The plan mod scope of work consists of adding sprinklers to mechanical rooms located in the basement. In addition, the pipe sizes of the existing main in the basement were wrong and have been corrected. Therefore, new hydraulic calculations were needed and have been provided. Only the ballooned areas indicated as PM have been reviewed in this submittal.
