ALL MECHANICAL, ELECTRICAL, AND PLUMBING WORK SHALL COMPLY WITH ALL

APPLICABLE STATE AND LOCAL BUILDING CODES. REFER TO SPECIFICATIONS FOR

MATERIALS AND METHODS FOR MECHANICAL CONSTRUCTION.

CONTRACTOR SHALL OBTAIN ALL NECESSARY PERMITS, PAY ALL FEES, AND COMPLY

WITH ALL NATIONAL, STATE, AND MUNICIPAL LAWS, CODES, AND ORDINANCES

RELATING TO BUILDING AND PUBLIC SAFETY.

CONTRACTOR SHALL FURNISH ALL MATERIALS, EQUIPMENT, AND LABOR REQUIRED

FOR A COMPLETE WORKING AND COORDINATED SYSTEM.

REFER TO ARCHITECTURAL DRAWINGS FOR LOCATIONS OF WALLS WHICH EXTEND TO

STRUCTURE. EACH HVAC DUCT OR PIPE PENETRATION THROUGH THESE WALLS SHALL

BE INSTALLED AS DETAILED. WHERE FLEXIBLE DUCT WOULD PENETRATE A WALL

WHICH EXTENDS TO STRUCTURE, PROVIDE INSULATED RIGID DUCT EXTENDING 12

INCHES ON EITHER SIDE OF THE PARTITION.

COORDINATE THE EXACT LOCATION OF MECHANICAL EQUIPMENT WITH THE

LOCATIONS OF LIGHT FIXTURES, PIPING, CONDUIT AND OTHER CONSTRUCTION, TO

ALLOW FOR PROPER ACCESS TO SERVICE EQUIPMENT.

COORDINATE THE LOCATION OF DUCTWORK AND PIPING WITH OTHER TRADES AND

PROVIDE OFFSETS IN DUCTWORK AND PIPING AS REQUIRED.

IT IS THE INTENT OF THESE DOCUMENTS TO ALLOW ALL CEILING CONSTRUCTION AND

HEIGHTS TO BE AS SHOWN ON THE ARCHITECTURAL DRAWINGS. COORDINATE THE

LOCATION OF DUCTWORK AND PIPING AND PROVIDE OFFSETS IN DUCTWORK AND

PIPING AS REQUIRED TO MEET THIS INTENT.

CONDUIT, PIPING, AND DUCTWORK SHALL BE INDEPENDENTLY SUPPORTED, AND EACH

SUPPORT SHALL BE INDEPENDENT OF PARTITION AND CEILING SYSTEMS SUPPORTS.

REFER TO RISER DIAGRAMS AND FLOW DIAGRAMS FOR PIPE SIZES NOT SHOWN ON

THE PLANS.

INSTALL ALL FLOOR MOUNTED EQUIPMENT ON PADS AS SPECIFIED. PAD BY GENERAL

CONTRACTOR. COORDINATE REQUIREMENTS WITH GENERAL CONTRACTOR.

PROTECT EQUIPMENT FROM DAMAGE DURING HANDLING AND INSTALLATION UNTIL

COMPLETION OF CONSTRUCTION.

REMOVE ALL EXCESS MATERIAL AND DEBRIS AND CLEAN ALL EQUIPMENT UPON

COMPLETION OF WORK. TOUCH UP WITH PAINT WHERE REQUIRED.

CONTRACTOR SHALL VISIT JOBSITE AND VERIFY SIZE AND LOCATION OF ALL EXISTING

ITEMS AND CONDITIONS.

ALL CONNECTIONS BETWEEN PIPES OF DISSIMILAR MATERIALS SHALL BE MADE WITH

DIELECTRIC UNIONS.

ALL EXISTING FACILITIES SHALL BE PROTECTED DURING THE CONSTRUCTION

ACTIVITIES. IT SHALL BE THE RESPONSIBILITY OF THE CONTRACTOR TO RELOCATE

AND STORE ITEMS WHICH ARE SUBJECT TO DAMAGE.

ARCHITECT SHALL HAVE FINAL APPROVAL OF ALL GRILLE, DIFFUSER, AND

THERMOSTAT LOCATIONS.

COORDINATE ALL AIR DEVICE LOCATIONS AND MOUNTING FRAME STYLES WITH

LIGHTING PLANS AND ARCHITECTURAL REFLECTED CEILING PLANS. PROVIDE 6'-0"

FROM CENTER TO CENTER FROM SUPPLY TO EXHAUST/RETURN GRILLES FOR PROPER

AIRFLOW.

COORDINATE ALL WALL MOUNTED DEVICE LOCATIONS WITH ARCHITECTURAL INTERIOR

ELEVATIONS.

REFER TO ARCHITECTURAL LIFE SAFETY PLANS FOR COORDINATION OF FIRE, SMOKE,

AND COMBINATION FIRE/SMOKE DAMPERS. THE DESIGN INTENT IS TO PROVIDE THE

INDICATED DAMPERS IN ACCORDANCE WITH REQUIREMENTS OF THE INTERNATIONAL

BUILDING CODE. THE CONTRACTOR SHALL PROVIDE ANY ADDITIONAL LIFE SAFETY

DAMPERS, INCLUDING FIRE ALARM CONTROL WIRING AND MONITORING REQUIRED BY

THE IBC AND LOCAL ORDINANCES AND CODE INTERPRETATIONS.

ALL DUCT RUN-OUTS TO VAV TERMINAL BOXES SHALL BE 2" LARGER THAN INLET SIZE

IF BOX IS MORE THAN 15 FT. FROM MAIN SUPPLY DUCT.

ANY DEVIATIONS FROM SCHEDULED EQUIPMENT RESULTING IN ADDITIONAL COST DUE

TO THE LACK OF COORDINATION WITH DIMENSIONS AND WEIGHTS WILL BE THE

RESPONSIBILITY OF THE CONTRACTOR.

ALL FIRE/SMOKE COMBINATION DAMPERS AND/OR FIRE DAMPERS SHALL BE INSTALLED

IN ACCORDANCE WITH THE MANUFACTURER'S INSTALLATION DETAILS THAT WERE

TESTED AT U.L. LABORATORIES AND U.L. LISTED.

X. WIRING:

COMBUSTIBLE ELECTRICAL OR ELECTRONIC WIRING METHODS AND MATERIALS,

OPTICAL FIBER CABLE, AND OPTICAL FIBER RACEWAYS EXPOSED WITHIN A PLENUM

SHALL HAVE A PEAK OPTICAL DENSITY NOT GREATER THAN .50, AN AVERAGE OPTICAL

DENSITY NOT GREATER THAN 0.15 AND A FLAME SPREAD NOT GREATER THAN 5 FEET

WHEN TESTED IN ACCORDANCE WITH NFPA 262. ONLY TYPE OFNP (PLENUM RATED

NON-CONDUCTIVE FIBER CABLE) SHALL BE INSTALLED IN PLENUM-RATED RACEWAYS.

WIRING, CABLE, AND RACEWAYS ADDRESSED IN THIS SECTION SHALL BE LISTED AND

LABELED AS PLENUM RATED AND SHALL BE INSTALLED IN ACCORDANCE WITH ICC

ELECTRICAL CODE.

Y. PROVIDE VOLUME AND BALANCING DAMPERS AS REQUIRED BY IMC 603.17 FOR EACH

BRANCH OR DIFFUSER. . PROVIDE LINKAGE VOLUME DAMPERS TO

DAMPERS LOCATED ABOVE HARD-LID CEILINGS SIMILAR TO YOUNG REGULATOR

MODEL 927C OR EQUIVALENT SOLID LINKAGE DAMPER.
