KEY PLAN

1. PROVIDE NEW WET-PIPE SPRINKLER PROTECTION IN ACCORDANCE

WITH NFPA 13 AND THE CONTRACT DOCUMENTS.

2. PROVIDE A COMPLETE SYSTEM DESIGN INCLUDING WORKING

DRAWINGS FROM THE CONTRACT DOCUMENTS.

3. EXISTING SYSTEM INFORMATION IS PROVIDED FOR GENERAL

REFERENCE ONLY AND IS NOT CONSIDERED TO BE AS-BUILT

CONDITIONS. ALL EXISTING CONDITIONS SHALL BE FIELD VERIFIED.

4. THE SHOPS, EQUIPMENT ROOMS, STORAGE AND SIMILAR AREAS ARE

ORDINARY HAZARD. THE OFFICES, CORRIDORS, RESTROOMS, AND

ASSEMBLY AREAS ARE LIGHT HAZARD.

5. THE SYSTEMS SHALL BE HYDRAULIC CALCULATED TO PROVIDE:

A. 0.2 GPM/SQ. FT OVER THE MOST REMOTE 2,500 SQ. FT. FOR

LIGHT HAZARD AREAS WITH CEILING HEIGHTS OVER 30 FT AND

ALL ORDINARY HAZARD AREAS

B. 0.1 GPM/SQ. FT. OVER THE MOST REMOTE 1,500 SQ. FT. FOR

LIGHT HAZARD AREAS WITH CEILING HEIGHTS 30 FT OR LESS.

6. 250 GPM OUTSIDE HOSE STREAM FOR ALL CALCULATIONS

FIRE SPRINKLER SYSTEM NOTES

6. PERFORM A HYDRANT FLOW TEST. BASE HYDRAULIC

CALCULATIONS ON THE LOWEST AVAILABLE PRESSURE OF THE NEW

FLOW TEST OR THE TEST PERFORMED ON 19 OCT 2016, WHICH WAS

PERFORMED ON HYDRANT 34 (PRESSURE HYDRANT LOCATED

APPROXIMATELY 150' NORTH OF THE NORTH EAST CORNER OF

BUILDING 417) AND HYDRANT 35 (FLOW HYDRANT LOCATED

APPROXIMATELY 70' NORTH OF THE NORTHEAST CORNER OF

BUILDING 417). THE STATIC PRESSURE WAS 79 PSI AND THE

RESIDUAL PRESSURE WAS 66 PSI @ 1,902 GPM.

7. PROVIDE HANGERS IN ACCORDANCE WITH NFPA 13 INCLUDING

SEISMIC BRACING.

8. PIPING SHALL BE BLACK STEEL WITH FURNACE BUTT-WELDS (ASTM

A53, TYPE F). ELECTRIC RESISTANCE-WELDED STEEL PIPE IS NOT

PERMITTED. PIPE SHALL BE SCHEDULE 40 EXCEPT SCHEDULE 10

PIPE MAY BE USED FOR WELDED AND GROOVED JOINTS IN SIZES

LARGER THAN 2 INCHES.

9. PROVIDE QUICK RESPONSE SPRINKLERS WITH SPACING PER NFPA

13 (EXTENDED COVERAGE SPRINKLERS ARE NOT PERMITTED).

SPRINKLERS SHALL BE RECESSED PENDENT AND CENTERED IN

TILES IN SUSPENDED TILE CEILINGS. PROVIDE UPRIGHTS IN AREAS

WITHOUT CEILINGS. PROVIDE SPRINKLER SIZES AS FOLLOWS:

A. 5.6 K-FACTOR FOR LIGHT HAZARD WITH CEILING HEIGHT LESS

THAN 30 FT

B. 8.0 K-FACTOR FOR ORDINARY HAZARD WITH CEILING HEIGHT

LESS THAN 30 FT

C. 11.2 K-FACTOR FOR ANY AREA WITH CEILING HEIGHT OVER 30 FT.

10. COORDINATE THE INSTALLATION OF THE SPRINKLERS WITH THE

HVLS FANS TO COMPLY WITH NFPA 13 AS FOLLOWS:

A. MAXIMUM FAN DIAMETER OF 24 FT

B. THE FANS ARE CENTERED BETWEEN 4 SPRINKLERS

C. 3-FT MINIMUM CLEARANCE FROM FANS TO SPRINKLER

DEFLECTOR

D. FANS INTERLOCKED WITH WATERFLOW ALARM TO SHUTDOWN

11. THE SCOPE OF WORK IS SHOWN ON THE DRAWINGS AND

SUMMARIZED AS FOLLOWS:

A. PROVIDE NEW SPRINKLER PROTECTION THROUGHOUT THE

FACILITY

B. DEMOLISH ALL EXISTING SPRINKLERS, PIPING, FOAM EQUIPMENT,

ETC. (REFER TO THE DEMOLITION PLANS)
