1. MODIFY THE EXISTING/PROVIDE A COMPLETE WET-PIPE SPRINKLER SYSTEM DESIGNED AND INSTALLED

PER USDA ARS MANUAL AND NFPA 13, 2025 CRITERIA AS INDICATED IN THE DRAWINGS AND

SPECIFICATIONS.

2. UNLESS OTHERWISE NOTED BY HATCHING, PROVIDE SPRINKLER SYSTEM DESIGN IN ACCORDANCE

WITH ORDINARY HAZARD GROUP 1 CRITERIA.

3. PROVIDE A MINIMUM SPRINKLER TEMPERATURE OF 155 FAHRENHEIT OR HIGHER FOR ORDINARY

TEMPERATURE SPRINKLERS.

4. PROVIDE BLACK STEEL SPRINKLER PIPE. PIPE 2-INCH AND BELOW MUST BE SCHEDULE 40, PIPE 2.5-

INCHES AND GREATER MUST BE MINIMUM SCHEDULE 10.

5. ALL REQUIRED OUTAGES OF THE SPRINKLER AND FIRE ALARM SYSTEM SHALL BE COORDINATED

THROUGH THE CONTRACTING OFFICER NOT LESS THAN 15 WORKING DAYS IN ADVANCE. THE

GOVERNMENT WILL PROVIDE THE REQUESTED OUTAGE AND ASSOCIATED RESTORATION OF THE

SPRINKLER SYSTEM. THE GOVERNMENT WILL IDENTIFY TO THE CONTRACTOR WHAT PIPING/EQUIPMENT HAVE BEEN TAKEN OUT OF SERVICE ONCE THE OUTAGE HAS BEEN MADE. THE GOVERNMENT WILL NOT DRAIN OR REFILL SPRINKLER PIPING AS PART OF AN OUTAGE. THIS WORK SHALL BE PERFORMED BY THE CONTRACTOR. OUTAGES DO NOT INCLUDE CONNECTION OF NEW WORK TO EXISTING SPRINKLER

PIPING.

6. A FIRE WATCH, AT CONTRACTOR'S COST, WILL BE CONDUCTED CONTINUOUSLY THROUGHOUT THE DURATION OF THE OUTAGE IN ALL AREAS AFFECTED BY THE OUTAGE. FOLLOW NFPA 241 CRITERIA FOR

OUTAGES. FINDINGS/COMMENTS WILL BE DOCUMENTED HOURLY ON FIRE WATCH FORMS.

DOCUMENTATION OF FINDINGS WILL BE MADE AVAILABLE TO THE FIRE DEPARTMENT OFFICIALS UPON THEIR REQUEST. IN THE EVENT OF ANY FIRE/SMOKE EMERGENCIES DISCOVERED DURING THE FIRE WATCH, EMERGENCY NOTIFICATION WILL BE PROVIDED TO THE PREDETERMINED POINT OF CONTACT

7. OUTAGES WILL NOT BE PERMITTED TO TAKE PLACE FOR THE ENTIRE DURATION OF THE PROJECT.

8. OVERNIGHT OUTAGES WILL NOT BE PERMITTED UNLESS WORK IS BEING DONE DURING THAT TIME PERIOD AND THE SPRINKLER SYSTEM IS PUT BACK INTO SERVICE WITHIN AN HOUR FROM COMPLETION OF WORK. OUTAGES SHALL BE LIMITED TO 8 HOURS INCLUDING TIME FOR DRAINING AND REFILLING.

9. THE SPRINKLER SYSTEM IS NOT PERMITTED TO HAVE AN OUTAGE FOR MORE THAN AN HOUR BEFORE STARTING WORK. THE SPRINKLER SYSTEM SHALL BE RESTORED WITHIN AN HOUR OF COMPLETION OF WORK. THE CONTRACTOR CANNOT LEAVE THE CONSTRUCTION SITE UNPROTECTED. THE SPRINKLER

SYSTEM SHALL BE FILLED WITHIN AN HOUR OF COMPLETION OF WORK.
