PROVIDE ALL ACCESSORIES REQUIRED FOR "LONG-LINE" APPLICATIONS. CONTRACTOR SHALL SUBMIT

CALCULATIONS IN ACCORDANCE WITH THE RECOMMENDATIONS OF THE MANUFACTURER.

19. THE BUILDING HAS A FIRE ALARM SYSTEM. PROVIDE A DUCT-MOUNTED SMOKE DETECTOR IN THE SUPPLY OF THE

AIR HANDLING UNIT. THE UNIT SHALL SHUT DOWN UPON ACTIVATION OF THE DEVICE. THE DUCT SMOKE

DETECTORS SHALL BE INSTALLED BY THE MECHANICAL CONTRACTOR. THE DUCT SMOKE DETECTORS SHALL BE

PROVIDED, WIRED, AND INTERFACED WITH THE FIRE ALARM SYSTEM BY THE ELECTRICAL CONTRACTOR.

20. ALL TEMPERATURE SENSORS/CONTROLS SHALL BE LOCATED TO ALLOW THE PARALLEL APPROACH BY A PERSON

IN A WHEELCHAIR AND MOUNTED 54" AFF. WHERE ONLY FORWARD APPROACH IS POSSIBLE, SENSORS/CONTROLS

SHALL BE MOUNTED 48" AFF.

21. THE CONTRACTOR SHALL PERFORM A COMPLETE CERTIFIED TEST AND BALANCE OF EACH MECHANICAL SYSTEM

IN ACCORDANCE WITH A NATIONAL STANDARD. SEE SPECIFICATIONS FOR DETAILS AND PROVIDE THREE (3)

WRITTEN COPIES OF THE COMPLETED TEST AND BALANCE REPORT TO THE OWNER AND ENGINEER FOR REVIEW

AND APPROVAL.

GENERAL NOTES

1. THIS PROJECT OCCURS IN AN EXISTING FACILITY THAT SHALL REMAIN IN OPERATION DURING CONSTRUCTION.

COORDINATION OF ALL WORK WITH THE OWNER SHALL BE REQUIRED. SCOPE OF WORK SHALL BE PERFORMED IN

PHASES. OUTAGES OF SHORT DURATION WILL BE ALLOWED AT THE SOLE DIRECTION OF THE OWNER.

2. THE CONTRACTOR SHALL VISIT THE SITE TO FAMILIARIZE HIMSELF WITH ALL EXISTING CONDITIONS.

3. THE WORK SHALL BE DONE COMPLETED IN TWO (2) PHASES. CONTRACTOR SHALL PROVIDE A SCHEDULE

INDICATING THE START DATE AND DURATION OF EACH PHASE OF CONSTRUCTION. THE SCHEDULE SHALL BE

REVIEWED BY THE OWNER AND DIRECTION GIVEN ON EACH UNIT REPLACEMENT.

4. IN GENERAL, THE MECHANICAL SCOPE OF PHASE 1 IS AS FOLLOWS:

a. EXISTING PENTHOUSE VENTILATION LOUVERS ARE TO BE REMOVED TO FACILITATE INSTALLATION OF

EQUIPMENT.

b. MULTI-ZONE AIR HANDLING UNIT AHU-1 SHALL BE REMOVED AND REPLACED WITH A UNIT OF EQUIVALENT OR

GREATER PERFORMANCE. INCLUDES MODIFICATIONS TO EQUIPMENT HOUSEKEEPING PAD, CHILLED WATER

CONNECTIONS, AND DUCTWORK CONNECTIONS.

c. PENTHOUSE DUCTWORK ASSOCIATED WITH AHU-1 SHALL BE DEMOLISHED AND REPLACED WITH NEW.

d. DUCT HEATERS DH 1-1, 1-2, 1-3, 1-4, 1-5 AND DUCT HUMIDIFIERS HUM 1-1, 1-2, 1-3, AND 1-4 INSTALLED IN ZONE

SUPPLY DUCTWORK WITHIN PENTHOUSE.

e. EXISTING OUTSIDE AIR INTAKE DUCTWORK DEMOLISHED AND NEW DUCTWORK CONNECTED TO AHU-1 AND

EXISTING OUTSIDE AIR INTAKE ROOF CAP.

f. NEW PRESSURIZATION CONTROL DUCTWORK AND FAN PRF 1-1 PROVIDED AND CONNECTED TO EXISTING

DISCHARGE LOUVER.

g. UPDATE CONTROLS AND SEQUENCES FOR THE INTEGRATION OF REPLACEMENT EQUIPMENT.

5. IN GENERAL, THE MECHANICAL SCOPE OF PHASE 1 IS AS FOLLOWS:

a. EXISTING PENTHOUSE VENTILATION LOUVERS ARE TO BE REMOVED TO FACILITATE INSTALLATION OF

EQUIPMENT.

b. MULTI-ZONE AIR HANDLING UNIT AHU-1 SHALL BE REMOVED AND REPLACED WITH A UNIT OF EQUIVALENT OR

GREATER PERFORMANCE. INCLUDES MODIFICATIONS TO EQUIPMENT HOUSEKEEPING PAD, CHILLED WATER

CONNECTIONS, AND DUCTWORK CONNECTIONS.

c. PENTHOUSE DUCTWORK ASSOCIATED WITH AHU-1 SHALL BE DEMOLISHED AND REPLACED WITH NEW.

d. DUCT HEATERS DH 1-1, 1-2, 1-3, 1-4, 1-5 AND DUCT HUMIDIFIERS HUM 1-1, 1-2, 1-3, AND 1-4 INSTALLED IN ZONE

SUPPLY DUCTWORK WITHIN PENTHOUSE.

e. EXISTING OUTSIDE AIR INTAKE DUCTWORK DEMOLISHED AND NEW DUCTWORK CONNECTED TO AHU-1 AND

EXISTING OUTSIDE AIR INTAKE ROOF CAP.

f. NEW PRESSURIZATION CONTROL DUCTWORK AND FAN PRF 1-1 CONNECTED TO EXISTING LOUVER.

g. UPDATE CONTROLS AND SEQUENCES FOR THE INTEGRATION OF REPLACEMENT EQUIPMENT.

6. THE FIELD PERSONNEL AT THE SITE WILL NEED SUFFICIENT TIME TO RELOCATE EXPERIMENTS AND TRANSITION

TO OTHER AREAS OF THE BUILDING PRIOR TO EACH AIR HANDING UNIT REPLACEMENT. IT WILL NOT BE POSSIBLE

FOR THE UNITS TO BE REPLACED AT THE SAME TIME AND THERE COULD BE A SIGNIFICANT TIME GAP BETWEEN

WHEN THE REPLACEMENT OF ONE UNIT IS COMPLETED AND THE SECOND UNIT REPLACEMENT BEGINS.

7. AREAS SERVED BY THE HVAC SYSTEMS MODIFIED IN THIS PROJECT INCLUDE SPACES RATED AS BIOHAZARD

SAFETY LEVELS 2 AND 3 (BSL-2 AND BSL-3). FIELD PERSONNEL MUST COORDINATE ANY ENTRY INTO THE

BSL-RATED SPACES WITH THE OWNER AND FOLLOW ALL SAFETY PROTOCOLS AS DIRECTED BY THE OWNER. ANY

PENETRATIONS IN AND OUT OF THE BSL-RATED SPACES MUST BE PROPERLY SEALED BY THE CONTRACTOR AND
