1. CODES AND STANDARDS LISTED IN SPECIFICATIONS AND DRAWINGS ARE MINIMUM STANDARDS. WHERE REQUIREMENTS ON THE DRAWINGS OR SPECIFICATIONS EXCEED THE MINIMUM CODE REQUIREMENTS, THE DRAWINGS OR SPECIFICATIONS SHALL GOVERN.

2. THE POWER RATING OF MOTORS AND OTHER MECHANICAL EQUIPMENT AND THE ELECTRICAL CHARACTERISTICS OF ELECTRICAL SYSTEMS SERVING THEM HAVE BEEN ESTABLISHED AS MINIMUMS WHICH ALLOW THAT EQUIPMENT TO FUNCTION PROPERLY TO PRODUCE THE REQUIRED CAPACITIES. POWER RATINGS INCLUDE REASONABLE SAFETY FACTORS TO ACCOMMODATE COMMON DIFFERENCES BETWEEN DESIGN PARAMETERS AND FIELD CONSTRUCTION PRACTICES. EQUIPMENT WITH POWER RATINGS LESS

THAN THOSE INDICATED ON THE DRAWINGS SHALL NOT BE PERMITTED.

3. REASONABLE EFFORTS HAVE BEEN MADE TO COORDINATE ELECTRICAL REQUIREMENTS OF MECHANICAL EQUIPMENT WITH THE ELECTRICAL SYSTEMS SERVING THAT EQUIPMENT. DIFFERENCES AMONG MANUFACTURERS OF MECHANICAL EQUIPMENT MAKE IT IMPOSSIBLE TO PRODUCE A SINGLE ELECTRICAL DESIGN WHICH WILL SATISFY THE VARYING ELECTRICAL REQUIREMENTS OF THE THOSE MANUFACTURERS. CONSEQUENTLY, THE CONTRACTOR SHALL COORDINATE THE ELECTRICAL REQUIREMENTS OF THE MECHANICAL EQUIPMENT ACTUALLY FURNISHED ON THIS PROJECT WITH THE EQUIPMENT ACTUALLY FURNISHED ON THIS PROJECT AND PROVIDE ELECTRICAL SYSTEMS REQUIRED BY THAT EQUIPMENT. THIS COORDINATION EFFORT SHALL BE COMPLETED PRIOR TO THE INSTALLATION OF EITHER THE MECHANICAL EQUIPMENT OR THE ELECTRICAL SYSTEMS SERVING THAT EQUIPMENT.

ELECTRICAL SYSTEM REVISIONS REQUIRED TO COORDINATE WITH THE MECHANICAL EQUIPMENT ACTUALLY FURNISHED SHALL BE

PROVIDED AT NO ADDITIONAL COST TO THE OWNER.

4. DRAWINGS INDICATE GENERAL LOCATIONS OF FIXTURES, APPARATUS, EQUIPMENT, PIPING, AND DUCTWORK. CHANGES ON LOCATION SHALL BE MADE TO ACCOMMODATE EXISTING OR NEW BUILDING CONDITIONS AND COORDINATION WITH OTHER TRADES, INCLUDING HVAC, PLUMBING, ELECTRICAL, FIRE PROTECTION, STRUCTURAL, AND ARCHITECTURAL, SHALL BE MADE WITHOUT

ADDITIONAL COST TO THE OWNER.

5. PROVIDE ACCESS TO EQUIPMENT AND PORTIONS OF BUILDING SYSTEMS REQUIRING SERVICE.

6. DO NOT INSTALL DUCTWORK, PIPING, OR EQUIPMENT IN ELECTRICAL ROOMS, ELEVATOR ROOMS, OR ELEVATOR SHAFTS, UNLESS EXPLICITLY INDICATED ON THE DRAWINGS. PIPING, DUCTWORK, AND EQUIPMENT (SWITCHGEAR, SWITCHBOARDS, PANELS, MOTOR CONTROL CENTERS, VARIABLE FREQUENCY DRIVES, TRANSFORMERS, OR STARTERS) SHALL NOT BE INSTALLED DIRECTLY ABOVE

OR 42" IN FRONT OF ELECTRICAL EQUIPMENT FROM THE FLOOR TO THE STRUCTURE ABOVE.

7. FOR RENOVATION PROJECTS WHERE THE BUILDING IS OCCUPIED, SCHEDULE WORK SO EXISTING SYSTEMS WILL BE INTERRUPTED FOR A MINIMUM AMOUNT OF TIME. OBTAIN APPROVAL FROM THE OWNER AND ARCHITECT AT LEAST 14 DAYS PRIOR TO INTERRUPTION OR CONNECTION. NO ALLOWANCE WILL BE MADE FOR LACK OF KNOWLEDGE OF EXISTING CONDITIONS.

8. UNLESS INDICATED OTHERWISE, EQUIPMENT AND MATERIALS SHALL BE NEW AND OF THE CUSTOMARY STANDARD AND QUALITY

FURNISHED BY THE DESIGNATED MANUFACTURER FOR THAT CATALOG NUMBER.

9. FOR EXISTING SYSTEMS, REMOVE EXPOSED PIPING AND DUCTWORK RENDERED USELESS DUE TO CHANGES. PLUG OUTLETS IN

PIPING. CAP AND SEAL OPENINGS IN DUCTWORK AND SEAL AIRTIGHT.

10. AIR SYSTEMS SHALL OPERATE WITHOUT AERODYNAMIC NOISE GENERATED FROM FAULTY INSTALLATION OF DUCTWORK, DIFFUSERS, OR ANY PORTION OF THE AIR DISTRIBUTION SYSTEM.

11. SUPPORT PIPING INDEPENDENTLY OF EQUIPMENT. HANGER RODS SHALL BE SUSPENDED FROM THE STRUCTURE. DO NOT SUSPEND

FROM OTHER PIPING, CONDUIT, EQUIPMENT, OR DUCTWORK.

12. ALL WORK REFERENCED UNDER DIVISION 23 SHALL BE DONE BY THE MECHANICAL CONTRACTOR.

GENERAL MECHANICAL NOTES:

1. INSTALL PIPING TO ALLOW ACCESS FOR VALVES, AIR

VENTS, AND EQUIPMENT REQUIRING ACCESSIBILITY, AND

TO PROVIDE MAXIMUM HEADROOM.

2. PROVIDE OFFSETS TO MAINTAIN CEILING HEIGHT AND TO

COORDINATE WITH OTHER TRADES.

3. INSTALL VALVES IN HORIZONTAL PIPING WITH VALVE

STEMS AT OR ABOVE THE PIPE CENTERLINE.

4. ARRANGE PIPING FOR VENTING OF AIR AND DRAINAGE OF

ENTIRE SYSTEM.

5. REPLACE EXISTING MECHANICAL PIPE HANGERS AND

PIPE FLOOR SUPPORTS WITH NEW TO SERVE EXISTING

MECHANICAL PIPING TO REMAIN IN ORDER TO

ACCOMMODATE THE INSTALLATIONOF ALL NEW

EQUIPMENT, SYSTEMS, AND DEVICES. MECHANICAL

CONTRACTOR SHALL VERIFY EXACT LOCATIONS AND

SIZES IN THE FIELD.

6. WHEREVER NEW PIPING IS JOINED TO EXISTING PIPING,

THE MECHANICAL CONTRACTOR SHALL PROPERLY SEAL

THESE CONNECTIONS WATERTIGHT AND INSULATE THESE

LOCATIONS WITH NEW INSULATION AS INDICATED IN THE

SPECIFICATION.

7. FOR COPPER AND STEEL PIPING GROOVED OR

MECHANICALLY FORMED T-TYPE FITTINGS ARE NOT

ACCEPTABLE.

8. LUBRICATE, EXERCISE, CLEAN AND TEST ALL EXISTING

VALVES AND STRAINERS FOR THE HEATING PLANT,

COOLING PLANT (CHILLED WATER AND CONDENSER

WATER), PIPE RISER TAKE-OFFS, 10TH FLOOR PUMP

ROOM, AND PIPE MAIN SHUTOFFS PER THE

MANUFACTURER'S INSTRUCTIONS.

1. CHANGES IN SHAPE OR DIMENSION SHALL BE MADE WITH

MAXIMUM TRANSITION OF 1 TO 7.

2. SEPARATE GALVANIZED SHEET METAL FROM ALUMINUM OR

COPPER PER THE SPECIFICATIONS.

3. PROVIDE SUPPLEMENTAL STIFFENING AND SUPPORTS TO

DUCTS AND APPARATUS CASINGS TO PREVENT DRUMMING,

SAGGING AND TO PROVIDE A STRUCTURALLY SOUND ASSEMBLY.

4. PROVIDE OFFSETS AND TRANSITIONS TO COORDINATE WITH

OTHER TRADES.

5. PROVIDE DUCTWORK AND TRANSITIONS TO CONNECT DUCTWORK TO

NEW OR EXISTING EQUIPMENT, DUCTWORK, AND COILS.

6. INSTALL FLEXIBLE PERMANENT DUCTWORK IN A FULLY EXTENDED

CONDITION WITHOUT SAGS AND KINKS.

7. MECHANICAL CONTRACTOR SHALL INSTALL DUCT MOUNTED SMOKE

DETECTORS IN ACCESSIBLE LOCATIONS. DETECTORS SHALL BE

FURNISHED AND WIRED BY THE ELECTRICAL CONTRACTOR. REFER

TO ELECTRICAL DRAWINGS FOR EXACT QUANTITY AND LOCATIONS.

8. INDICATED DIMENSIONS DENOTE FREE AND CLEAR INSIDE

DIMENSIONS.

9. REPLACE EXISTING DUCT HANGERS WITH NEW TO SERVE EXISTING

DUCTWORK TO REMAIN IN ORDER TO ACCOMMODATE THE

INSTALLATION OF ALL NEW EQUIPMENT, SYSTEMS, AND DEVICES.

MECHANICAL CONTRACTOR SHALL VERIFY THE EXACT LOCATIONS

AND SIZES IN THE FIELD.

10. WHEREVER NEW DUCTWORK IS JOINED TO EXISTING DUCTWORK,

THE MECHANICAL CONTRACTOR SHALL PROPERLY SEAL THESE

CONNECTIONS AIRTIGHT AND INSULATE THESE LOCATIONS WITH NEW

INSULATION AS INDICATED IN THE SPECIFICATION.

GENERAL PIPING NOTES: GENERAL DUCTWORK NOTES:

1. TRANSFORMERS OR FILTERS FOR OPERATION OF AUTOMATIC TEMPERATURE CONTROLS FROM BUILDING POWER

CIRCUITS SHALL BE PROVIDED UNDER DIVISION 23.

2. LOW VOLTAGE WIRING (LOWER THAN 110 VOLTS) FOR INTERLOCKED DEVICES, DDC CONTROLLERS, TERMINAL CONTROL UNITS, FLOW MEASURING DEVICES, AND OTHER POWER CONSUMING CONTROL DEVICES SHALL BE FURNISHED AND INSTALLED BY THE MECHANICAL CONTRACTOR. ALL LOW VOLTAGE WIRING SHALL BE INSTALLED IN

A CONDUIT AND SHALL BE PLENUM RATED.

3. WIRING 110 VOLTS AND HIGHER FOR INTERLOCKED DEVICES, DDC CONTROLLERS, TERMINAL CONTROL UNITS, FLOW MEASURING DEVICES, AND OTHER POWER CONSUMING CONTROL DEVICES SHALL BE FURNISHED AND INSTALLED BY THE ELECTRICAL CONTRACTOR WITH DIVISION 26 REQUIREMENTS. COORDINATE WITH THE ELECTRICAL

CONTRACTOR.

4. BRANCH CIRCUIT WIRING AND CONDUIT FURNISHED FOR CONTROL EQUIPMENT POWER SHALL BE SEPARATE FROM OTHER POWER WIRING. EACH CIRCUIT SHALL EXTEND TO A 120V BRANCH CIRCUIT PANEL, AND IDENTIFIED 120V, 20 AMPERE, SINGLE POLE BRANCH CIRCUIT BREAKER FURNISHED IN THE PANEL TO SERVE THE CIRCUIT. NO MORE THAN 2 DDC CONTROLLER INSTALLATIONS SHALL OPERATE FROM A SINGLE 120V BRANCH CIRCUIT, UNLESS

INDICATED OTHERWISE.

5. WHERE SYSTEMS ARE SERVED BY EMERGENCY POWER, CONTROLS FOR OPERATION OF THOSE SYSTEMS SHALL

ALSO BE SERVED BY EMERGENCY POWER.

6. WHERE DAMPERS PREVENT AIRFLOW THROUGH AN AIR HANDLING UNIT OR FAN, THOSE DAMPERS SHALL BE PROVEN OPEN PRIOR TO STARTING THE UNIT OR FAN. PROOF SHALL BE BY MECHANICAL SAFETY LIMIT SWITCH ACTIVATED BY THE DAMPER BLADE. FOR SERVICE WITH VARIABLE FREQUENCY DRIVES THE SWITCH SHALL BE WIRED IN THE AUTOMATIC AND HAND/TEST POSITIONS AND IN THE BYPASS POSITION FOR VARIABLE FREQUENCY DRIVES WITH

BYPASS.

7. ALL AIR PIPING OR TUBING SHALL BE PLENUM RATED. MECHANICAL CONTRACTOR SHALL FURNISH ALL AIR PIPING

AND TUBING REQUIRED FOR AUTOMATIC CONTROLS SYSTEMS.

8. PROVIDE SUPPLEMENTAL STIFFENING AND SUPPORTS TO DUCTS AND APPARATUS CASINGS TO PREVENT
