THIS PROJECT CONSISTS OF WORK IN MULTIPLE SPACES LOCATED IN DIFFERENT BUILDINGS. WORK SHALL BE COMPLETED IN A MANNER THAT MINIMIZES SHUTDOWNS TO NO MORE THAN ONE

AIR HANDLING UNIT AT A TIME.

THE FOLLOWING PHASES SHALL BE COMPLETED IN THE ORDER BELOW. DURATIONS LISTED SHALL BE FROM VA'S NOTICE TO PROCEED TO SUBSTANTIAL COMPLETION:

PHASE 1 - SUBMISSION OF EQUIPMENT AND CONTROLS FOR REVIEW AND APPROVAL. CONTRACTOR SCHEDULING AND REVIEW WITH VA (SEE NOTES BELOW) - 28 DAYS.

PHASE 2 - ALL WORK ASSOCIATED WITH AC-6. DURATION - 21 DAYS.

PHASE 3 - ALL WORK ASSOCIATED WITH AC-57. DURATION - 30 DAYS.

PHASE 4 - ALL WORK ASSOCIATED WITH AC-26. DURATION - 28 DAYS.

PHASE 5 - ALL WORK ASSOCIATED WITH AC-28. DURATION - 21 DAYS.

PHASE 6 - ALL WORK ASSOCIATED WITH AC-61 & AC-62. DURATION - 60 DAYS.

ESTIMATED PROJECT DURATION IS 224 DAYS.

CONTRACTOR SHALL USE THE PHASING OUTLINED ABOVE AND DEVELOP A SCHEDULE FOR REVIEW AND APPROVAL BY THE COR. CONTRACTOR PHASING PLAN SHALL DETAIL THE SEQUENCE OF WORK TO BE COMPLETED TO COMPLY WITH ITEM "A" ABOVE. THE PHASING AND SCHEDULE SUBMITTED BY THE CONTRACTOR IS SUBJECT TO CHANGE AT THE DISCRETION OF THE VA.

CONTRACTOR SCHEDULE REQUIREMENTS ARE OUTLINED IN THE SPECIFICATIONS AND SHALL INCLUDE THE FOLLOWING:

1. BROKEN DOWN BY MECHANICAL ROOM AND AIR HANDLING UNIT.

2. INCLUDE START DATES AND END DATES FOR EACH TASK.

3. TASKS FOR EACH TRADE; DEMOLITION, NEW PIPING, INDSULATION, CONTROLS, ELECTRICAL, ETC.

4. DURATIONS FOR EACH TASK.

5. INCLUDE AIR HANDLING UNIT SHUTDOWN DATES AND DURATIONS.

ALL WORK INSIDE OF THE AIR HANDLING UNITS THAT REQUIRE A SHUTDOWN SHALL BE COMPLETED ON 3RD SHIFT ON A WEEKEND. CONTRACTOR SHALL SUBMIT A SHUTDOWN PLAN TO THE VA WITH SPECIFIC START AND END DATES AND TIMES. AIR HANDLING UNIT SHUTDOWN TIMES WILL NEED TO BE SCHEDULED WITH EACH DEPARTMENT AFFECTED AND WILL LIKELY BE LIMITED TO A FEW HOURS (THIS MAY CHANGE AT THE DISCRETION OF THE VA). CONTRACTORS MAY HAVE TO COMPLETE THEIR WORK OVER MULTIPLE SHUTDOWNS IF THE AVAILABLE TIMES ARE NOT

SUFFICIENT TO COMPLETE ALL WORK NECESSARY.

CONTRACTOR SHALL FIELD VERIFY ALL WORK SHOWN ON THESE DRAWINGS AND NOTIFY THE COR AND DESIGN TEAM OF ANY CONDITIONS THAT PREVENT THE INTENDED DESIGN FROM BEING

CONSTRUCTED.

THE CONTRACTOR SHALL BE RESPONSIBLE FOR COORDINATING ALL TRADES ASSOCIATED WITH THIS PROJECT AND ISSUING COORDINATION PLANS PRIOR TO COMMENCEMENT OF EACH PHASE

OF CONSTRUCTION.

THE COORDINATION DRAWINGS SHALL ILLUSTRATE ALL SYSTEMS IN PLACE. THE CONTRACTOR SHALL SHOW ALL NECESSARY OFFSETS, TRANSITIONS, ETC. AS REQUIRED IN ORDER TO

ACCOMMODATE CONDITIONS IDENTIFIED IN THE FIELD.

HUMIDIFIER CONTROL NOTES

HUMIDIFIER CONTROL SEQUENCE

THE CONTROLLER SHALL MEASURE THE RETURN AIR HUMIDITY AND MODULATE THE STEAM CONTROL VALVE TO MAINTAIN A MINIMUM SETPOINT OF:

AC-6 - 40% RH(ADJ.)

AC-26 - 45% RH(ADJ.)

AC-28 - 45% RH(ADJ.)

AC-57 - 30% RH(ADJ.)

AC-61 - 30% RH(ADJ.)

AC-62 - 30% RH(ADJ.)

THE HUMIDIFIER SHALL BE ENABLED WHENEVER THE SUPPLY FAN STATUS IS ON AND THE RETURN AIR RELATIVE HUMIDITY IS BELOW THE SETPOINT LISTED IN ITEM 1.

THE HUMIDIFIER SHALL TURN OFF WHENEVER: RETURN AIR HUMIDITY MEASURES MORE THAN 10% OF THE SETPOINT LISTED IN ITEM 1 OR ON A LOSS OF SUPPLY FAN STATUS.

ALARMS:

A. HIGH SUPPLY AIR HUMIDITY +15%(ADJ) OF SETPOINT IN ITEM 1 (MEASURED IN RETURN AIR DUCT).

B. LOW SUPPLY AIR HUMIDITY -5%(ADJ) OF SETPOINT IN ITEM 1 (MEASURED IN RETURN AIR DUCT).

CONTRACTOR SHALL PROVIDE THE FOLLOWING NEW CONTROL DEVICES FOR EACH HUMIDIFIER:

A. SUPPLY AIR HIGH LIMIT HUMIDITY SENSOR (LOCATED IN SUPPLY AIR DUCT DOWNSTREAM OF AIR HANDLING UNIT, IN MECHANICAL SPACE) B. RETURN AIR HUMIDITY SENSOR (LOCATED IN RETURN AIR DUCT UPSTREAM OF AIR HANDLING UNIT, IN MECHANICAL SPACE)

C. CONTROL VALVE (SEE SCHEDULE AND DETAILS)

AT THE COMPLETION OF EACH PHASE THE CONTRACTOR SHALL TEST THE AIR HANDLING UNIT TO VERIFY THE HUMIDIFICATION SEQUENCE DETAILED BELOW IS MET. CONTRACTOR SHALL PROVIDE A REPORT THAT DETAILS EXACT LOCATIONS OF NEW CONTROL DEVICES LISTED IN ITEM 1 ABOVE AND WRITTEN VERIFICATION THAT THE HUMIDIFICATION CONTROL SEQUENCE

BELOW IS OPERATIONAL.
