PROVIDE ACCESS DOORS UPSTREAM OF ALL ELBOWS WITH TURNING VANES.

5. LOCATE ALL MECHANICAL EQUIPMENT (RTU'S, RETURN/EXHAUST FANS, DUCTWORK) FOR UNOBSTRUCTED ACCESS TO

UNIT ACCESS PANELS, CONTROLS, AND VALVING.

6. PROVIDE FLEXIBLE CONNECTIONS IN ALL DUCTWORK SYSTEMS (SUPPLY, RETURN, AND EXHAUST) CONNECTED TO AIR HANDLING UNITS , FANS, AND OTHER EQUIPMENT THAT REQUIRE VIBRATION ISOLATION. FLEXIBLE CONNECTIONS SHALL BE

PROVIDED AT THE POINT OF CONNECTION TO THE EQUIPMENT UNLESS OTHERWISE INDICATED.

7. CONTROL WIRING OF SMOKE DETECTORS IS BY THE APPROVED CONTROLS CONTRACTOR.

8. SAFETY DEVICES SHALL BE HARDWIRED TO THE FAN STARTER CIRCUIT, IN ADDITION TO THE DDC SYSTEM.

9. UNLESS OTHERWISE NOTED, ALL DUCTWORK IS OVERHEAD, TIGHT TO THE UNDERSIDE OF AN EXISTING DUCTWORK OR

STRUCTURE, WITH SPACE FOR INSULATION IF REQUIRED.

10. ALL DUCTWORK SHALL BE COORDINATED WITH ALL TRADES INVOLVED. OFFSETS IN DUCTS, INCLUDING DIVIDED DUCTS

AND TRANSITIONS AROUND OBSTRUCTIONS, SHALL BE PROVIDED AT NO ADDITIONAL COST TO THE OWNER.

11. PROVIDE ACCESS DOORS IN DUCTWORK TO PROVIDE ACCESS FOR ALL SMOKE DETECTORS, FIRE DAMPERS, VOLUME

DAMPERS, COILS AND OTHER ITEMS LOCATED IN THE DUCTWORK THAT REQUIRE SERVICE AND/ OR INSPECTION.

12. PROVIDE ACCESS DOORS IN DUCTWORK FOR THE OPERATION, ADJUSTMENT, AND MAINTENANCE OF ALL FANS, VALVES, AND MECHANICAL EQUIPMENT.

13. ALL DUCTS SHALL BE GROUNDED ACROSS FLEXIBLE CONNECTIONS WITH FLEXIBLE COPPER GROUNDING STRAPS.

14. SMOKE DETECTORS SHALL BE FURNISHED AND WIRED BY THE ELECTRICAL CONTRACTOR. THE MECHANICAL

CONTRACTOR SHALL BE RESPONSIBLE FOR MOUNTING THE SMOKE DETECTOR IN DUCTWORK AS SHOWN ON THE

DRAWINGS AND IN ACCORDANCE WITH THE MANUFACTURER'S PRINTED INSTRUCTIONS.

15. SEE SPECIFICATIONS FOR DUCTWORK GAUGES, BRACING, HANGERS, AND OTHER REQUIREMENTS.

16. FIRE ALARM CONTRACTOR SHALL FURNISH FIRE ALARM COMPLIANT SMOKE DETECTOR TO THE SHEET METAL

CONTRACTOR FOR FIELD DUCTWORK INSTALLATION, AS APPLICABLE. DIVISION 16 CONTRACTOR SHALL PROVIDE ALL

SIGNAL AND CONTROL POWER WIRING.

17. SUPPLY AND RETURN AIR DUCTS AND PLENUMS SHALL BE INSULATED WITH NOT LESS THAN R--6 INSULATION WHERE LOCATED IN UNCONDITIONED SPACES AND WHERE LOCATED OUTSIDE THE BUILDING WITH NOT LESS THAN

R-8 INSULATION IN CLIMATE ZONES 1 THROUGH 4.

18. THE CONTRACTOR SHALL PROVIDE CONSTRUCTION DOCUMENTS TO THE BUILDING OWNER WITHIN 90 DAYS OF THE DATE OF RECEIPT OF THE CERTIFICATE OF OCCUPANCY. THOSE DOCUMENTS INCLUDE: DRAWINGS, MANUALS, AND SYSTEM

BALANCING REPORTS.

19. HVAC SYSTEMS SHALL BE BALANCED IN ACCORDANCE WITH GENERALLY ACCEPTED ENGINEERING STANDARDS, AIR AND WATER FLOW RATES SHALL BE MEASURED AND ADJUSTED TO DELIVER FINAL FLOW RATES WITHIN TOLERANCES PROVIDED IN PRODUCT SPECIFICATIONS. TEST AND BALANCING ACTIVITIES SHALL INCLUDE AIR SYSTEM BALANCING.

CONTRACTOR SHALL PROVIDE SIGNED AND SEALED COPY OF TESTING AND BALANCING OF AIR REPORT.
