1. INSTALLATION OF HVAC WORK SHALL BE COORDINATED WITH OTHER TRADES BEFORE ANY INSTALLATION IS DONE. DUCTWORK SHOWN ON PLANS IS SCHEMATIC. PROVIDE ALL TRANSITIONS, ELBOWS, ETC. REQUIRED TO AVOID CONFLICTS & MAXIMIZE CEILING HEIGHTS. EQUIPMENT, PIPING OR DUCTWORK INTERFERING WITH OTHER TRADES SHALL BE RELOCATED AS REQUIRED AT NO

ADDITIONAL COST TO THE OWNER.

2. COORDINATE MECHANICAL AND ELECTRICAL SUCH THAT MECHANICAL PIPING, DUCTWORK AND EQUIPMENT IS NOT LOCATED OVER OR

ABOVE ANY ELECTRICAL, COMMUNICATIONS, OR DATA EQUIPMENT.

3. AT START OF CONSTRUCTION, PREPARE TYPED LISTS OF EQUIPMENT THAT ARE SUPPLIED REQUIRING ELECTRICAL WORK, AND SEND

LISTS TO THE ELECTRICAL CONTRACTOR FOR REVIEW AND COORDINATION.

4. WRITTEN DIMENSIONS ON DRAWINGS SHALL HAVE PRECEDENCE OVER SCALED DIMENSIONS. VERIFY DIMENSIONS ON SITE.

5. EQUIPMENT SHALL BE INSTALLED IN ACCORDANCE WITH MANUFACTURER'S APPROVED CLEARANCE, UNIFIED FACILITIES CRITERIA, AND INTERNATIONAL BUILDING CODE / INTERNATIONAL MECHANICAL CODE.

6. INSTALLATION OF EQUIPMENT SHALL PERMIT ACCESSIBILITY FOR SERVICE AND/OR REPLACEMENT WITHOUT NECESSITATING

REMOVAL OR MODIFICATION TO OTHER PIPING, WIRING, OR EQUIPMENT.

7. CEILING-MOUNTED EQUIPMENT SHALL BE INSTALLED IN SUCH A MANNER THAT LIGHTS, PIPING, DUCTWORK, ETC., DO NOT BLOCK

ACCESS TO EQUIPMENT AND RELATED ACCESSORIES.

8. DUCTWORK AIR DISTRIBUTION SYSTEMS SHALL BE INSTALLED IN ACCORDANCE WITH SMACNA STANDARDS AND THE PRESSURE

CLASSIFICATION OF EACH INDIVIDUAL DUCTWORK SYSTEM.

9. VOLUME DAMPERS SHALL BE PROVIDED AT EACH MAIN BRANCH TAKE-OFF, EACH TAKEOFF TO DIFFUSERS/GRILLS/REGISTERS, AND OTHER LOCATIONS WHERE REQUIRED TO PROPERLY BALANCE THE SYSTEM. ALL REQUIRED VOLUME DAMPERS MAY NOT BE SHOWN

ON PLANS.

10. INSTRUMENT TEST HOLES SHALL BE PROVIDED IN AIR DISTRIBUTION SYSTEMS WHEREVER VOLUME DAMPERS ARE INSTALLED. TEST

HOLES SHALL BE SEALED WITH RUBBER OR PLASTIC TEST HOLE PLUGS.

11. SQUARE ELBOWS SHALL ONLY BE USED WHERE SPACE LIMITATIONS PREVENT USE OF 1.5 RADIUS ELBOW AND ONLY UPON APPROVAL OF CONTRACTING OFFICER. PROVIDE TURNING VANES IN ALL SQUARE ELBOWS GREATER THAN OR EQUAL TO 45°. TURNING VANES SHALL BE SINGLE THICKNESS TYPE WITHOUT RAILING EDGE. TURNING VANES LONGER THAN 36 INCHES SHALL BE DOUBLE THICKNESS

TYPE.

12. DUCTWORK RUNOUTS TO AIR DISTRIBUTION DEVICES SHALL BE SAME DIAMETER AS AIR DISTRIBUTION DEVICE INLET CONNECTION

UNLESS OTHERWISE NOTED ON THE DRAWINGS.

13. FLEXIBLE DUCTWORK RUNOUTS FROM BRANCH DUCTS TO AIR DISTRIBUTION DEVICES SHALL NOT EXCEED 5 FEET IN LENGTH. BENDS IN FLEXIBLE DUCTWORK SHALL NOT EXCEED A MAXIMUM OF 45 DEGREE CHANGE OF DIRECTION AND SHALL BE SUPPORTED SUCH THAT THE BEND RADIUS IS NOT RESTRICTIVE TO AIR FLOW THROUGH THE DUCT. FLEXIBLE DUCTWORK SHALL NOT BE CRUSHED OR

DISTORTED IN ITS FINAL CONFIGURATION.

14. PROVIDE SHEETMETAL TRANSITIONS AT AIR HANDLING UNITS, HEAT PUMP UNITS, FANS, AND OTHER SIMILAR HVAC EQUIPMENT.

TRANSITION TO FULL SIZE OF CONNECTION ON UNIT. FLEXIBLE DUCT CONNECTORS SHALL BE USED ON FINAL CONNECTION TO AIR

HANDLING EQUIPMENT.

15. EXACT LOCATION OF CEILING DIFFUSERS, GRILLES AND REGISTERS SHALL BE DETERMINED BY ARCHITECTURAL REFLECTED CEILING

PLAN.

16. EXACT LOCATIONS OF THERMOSTATS, CO2 SENSORS, AND EMCS SENSORS SHALL BE COORDINATED WITH FINAL LOCATIONS OF WALL-MOUNTED ARCHITECTURAL AND ELECTRICAL EQUIPMENT. MOUNT THERMOSTATS AND CO2 SENSORS MINIMUM 48" AFF.

17. SPECIFICATIONS TAKE PRECEDENCE OVER DRAWINGS. HOWEVER, ITEMS SHOWN ON DRAWING BUT NOT IN THE SPECIFICATIONS ARE REQUIRED WITHIN THE PROJECT SCOPE. IN ADDITION, SPECIFIC ITEMS SHOWN ON THE DRAWINGS TAKE PRECEDENCE OVER

SPECIFICATIONS IN CASES WHERE THE SPECIFICATION HAS OPTIONS.

18. DUCT SIZES SHOWN ARE INSIDE CLEAR DIMENSIONS.

19. EXPOSED DUCTWORK, WITH THE EXCEPTION OF DUCTWORK IN MECHANICAL ROOMS SHALL BE DOUBLE-WALL, DUCTWORK WITH

COATING.

20. NOT ALL MECHANICAL ABBREVIATIONS SHOWN WILL BE USED FOR THIS PROJECT.

21. ALL THERMOSTATS SHALL BE WALL MOUNTED AND WIRED.

22. ALL EQUIPMENT INSTALLED IN THIS PROJECT SHALL COMPLY WITH THE "BUY AMERICAN ACT". BASIS OF DESIGN SHOWN ON SCHEDULES IS TO ESTABLISH A STANDARD OF QUALITY, NOT TO LIMIT COMPETITION. EQUIVALENT EQUIPMENT FROM ANOTHER MANUFACTURER IS ACCEPTABLE. MANUFACTURER NAME AND MODEL NUMBERS ARE BASIS OF DESIGN AND ARE SHOWN FOR

INFORMATION ONLY. REFER TO SPECIFICATIONS FOR COMPLETE REQUIREMENTS.

23. ALL COMMUNICATIONS PREMISE WIRING AND CABLE TRAYS THROUGHOUT THE FACILITY MUST BE PROTECTED AND UNINTERRUPTED DURING CONSTRUCTION. THIS INCLUDES ELECTRICAL POWER TO COMMUNICATIONS EQUIPMENT. NO COMMUNICATIONS OUTAGES MUST TAKE PLACE WITHOUT THE CONSENT OF THE CONTRACTING OFFICER.

24. CONTRACTOR MUST DEMOLISH ALL EQUIPMENT, PIPING, DUCTWORK, INSULATION, SUPPORTS, CONTROLS THERMOSTATS, WIRING AND ALL APPURTENANCES WITH THE HVAC SYSTEM TO BE DEMOLISHED.

25. CONTROLS CONTRACTOR SHALL PROVIDE ALL LOW VOLTAGE DEVICES, CONDUCTORS, AND PATHWAYS IN ACCORDANCE WITH THE REQUIREMENTS OF 26 20 00. INSTALL CONTROL WIRING IN CONDUIT. SEE DIVISION 26 SPECIFICATIONS FOR REQUIREMENTS.

26. THE DESIGN INTENT OF THIS PROJECT IS TO REPLACE THE EXISTING CONTROLS SYSTEM IN ITS ENTIRETY, EXCLUDING EXISTING TO REMAIN ITEMS BUT INCLUDING ALL CONTROL PANELS, DEVICES, WIRING, COMPONENTS, AND ASSOCIATED APPURTENANCES TO BE DEMOLISHED NECESSARY TO PROVIDE A COMPLETE, FULLY FUNCTIONAL, AND OPERATIONAL SYSTEM. ALL EXISTING EQUIPMENT INDICATED TO REMAIN MUST BE COMPLETELY CONNECTED TO AND FULLY INTEGRATED WITH THE NEW CONTROLS SYSTEM. THE NEW CONTROLS SYSTEM MUST MAINTAIN ALL EXISTING MONITORING, CONTROL, TRENDING, INTERLOCK, AND ALARM FUNCTIONS CURRENTLY PROVIDED BY THE EXISTING SYSTEM. ALL EXISTING CONTROL POINTS, WHETHER SPECIFICALLY INDICATED ON THE DRAWINGS OR NOT, MUST BE MAINTAINED AND INCORPORATED INTO THE NEW SYSTEM. CONTRACTOR MUST FIELD-VERIFY ALL EXISTING CONTROL POINTS, SEQUENCES OF OPERATION, INTERLOCKS, AND CONNECTIONS PRIOR TO INSTALLATION. UPON COMPLETION OF THE CONTROLS SYSTEM WORK, ALL NEW AND EXISTING EQUIPMENT AFFECTED BY THIS PROJECT MUST BE TESTED, CALIBRATED, AND BALANCED AS REQUIRED TO VERIFY PROPER SYSTEM OPERATION AND

PERFORMANCE IN ACCORDANCE WITH THE FINAL SEQUENCES OF OPERATION.

27. ALL EQUIPMENT PROVIDED MUST BE SELECTED FOR USE IN A COASTAL ENVIRONMENT AND MUST HAVE 3000 HOUR DURATION TEST FOR OUTSIDE EQUIPMENT AND EQUIPMENT BRINGING IN OR IN CONTACT WITH OUTDOOR AIR. PROVIDE MECHANICAL EQUIPMENT COILS WITH A MANUFACTURE APPROVED COATING SYSTEM THAT IS DESIGNED FOR A 5000 HOUR DURATION SALT

SPRAY TEST.
