The Fire Sprinkler Scope of work consists of system 8 ONLY. This system protects approximately half of the subfab area (lower level). The sprinklers are space at the junction of the concrete waffle construction. The system is a 4”x4”x1½” grid. The system is supplied by two 8” connections to a 10” loop underground. The two 8” lead ins are equipped with a yard PIV. A free standing FDC on top of a pit is also included in this scope of work. There is additional fire protection below three large ducts running east to west due to obstruction issues.

Plan Mod #1
The underground supply feeding the north riser was changed from a loop supply into the building to a dead end feed into the building. The north riser was revised accordingly.
