The Fire Sprinkler Scope of work consists of (3) levels of fire protection. The lowest level (basement) is divided into two sections, one existing and one new. The new 6”x140’ C-900 underground enters the lowest level (new basement) on the east side. A 4” bulk main goes west approximately half way across the building to supply the main header. The main riser with 4” RPZ backflow preventer supplies control valves for each level. There is a remote FDC located east of the building. The lowest level (basement) and middle level (main) are gridded; the top level (attic) utilizes attic sprinklers. The middle level (main) also has sprinklers on an intermediate level to protect above catwalks.
