COORDINATE ALL DUCTWORK ROUTING WITH ALL OTHER TRADES TO

INSURE ADEQUATE CLEARANCES FOR PLUMBING, ELECTRICAL

CONDUIT, STRUCTURAL SUPPORTS, PIPING, ETC. ANY UNAVOIDABLE

CONFLICTS SHALL BE BROUGHT TO THE ATTENTION OF THE

ARCHITECT/ENGINEER OF RECORD. PROVIDE ALL OFFSETS AND

TRANSITIONS AS REQUIRED FOR A CLEAN INSTALLATION.

SUPPORT ALL DUCTWORK DIRECTLY TO STRUCTURE. DO NOT

SUPPORT ANY DUCTS FROM DUCTWORK, CONDUIT, OR OTHER PIPING

ENCOUNTERED.

UNLESS NOTED OTHERWISE, ALL TAKE-OFFS TO VAV BOXES SHALL BE

THE SAME SIZE AS THE VAV INLET CONNECTION.

UNLESS NOTED OTHERWISE, ALL TAKE-OFFS TO DIFFUSERS, GRILLES

AND REGISTERS SHALL BE THE SAME SIZE AS THE DIFFUSER NECK OR

GRILLE/REGISTER CONNECTION.

ALL FIRE, SMOKE, AND COMBINATION FIRE/SMOKE DAMPERS

INSTALLED IN SHAFT WALLS SHALL BE INSTALLED TO ALLOW FOR

SERVICE OF THEIR FUSABLE LINK/ACTUATOR PER FACILITY

STANDARDS. ANY CONFLICTS WHICH WILL PREVENT ACCESS SHALL BE

BROUGHT TO THE ATTENTION OF THE ARCHITECT AND ENGINEER OF

RECORD.

MECHANICAL CONTRACTOR SHALL REVIEW ARCHITECTURAL CEILING

PLANS FOR LOCATIONS OF GYPSUM BOARD. DO NOT INSTALL VALVES,

VAV BOXES, SENSOR, OR DAMPERS ABOVE GYPSUM BOARD CEILINGS.

MECHANICAL CONTRACTOR SHALL REVIEW ARCHITECTURAL CEILING

PLANS FOR LOCATIONS OF GYPSUM BOARD CEILINGS AND

BULKHEADS. ADJUST PIPE AND DUCT THAT RUN PARALLEL TO

BULKHEAD FRAMING TO BE EITHER OUTSIDE OF FRAMING OR

BETWEEN FRAMING. MECHANICAL CONTRACTOR SHALL COORDINATE

WITH GENERAL CONTRACTOR FOR MODIFIED BULKHEAD FRAMING

WHERE EXISTING AND NEW PIPING AND DUCT WILL CAUSE

INTERFERENCE.

PROVIDE EACH NEW SUPPLY DIFFUSER/GRILLES WITH A SINGLE BLADE

TAKE-OFF DAMPER WITH QUADRANT LOCKING DEVISE. PERFORM ALL

BALANCING OF NEW DIFFUSERS THROUGH THOSE TAKE-OFF

DAMPERS. ALL NEW RETURN/EXHAUST GRILLES WILL BE PROVIDED

WITH OPPOSED BLADE BALANCING DAMPERS POSITIONED UPSTREAM

PAST A MINIMUM OF ONE TRANSITION FOR SOUND ABATEMENT.

BALANCING ANY DIFFUSERS/GRILLES USING INTEGRAL DAMPERS WILL

NOT BE AN APPROVED METHOD OF BALANCING.

DO NOT ROUTE DUCTWORK OVER THIS ROOM.

PROVIDE AND INSTALL FOUR (4) DUROZONE , EXTERNAL GEAR DRIVEN

CABLE OPERATED DAMPER IN LOCATION SHOWN. PROVIDE TWO (2)

WITH 15'-0" CABLES AND TWO (2) WITH 5'-0" CABLES. VERIFY CABLE

LENGTHS. (BALANCING OF RETURN AIR DIFFUSERS IN ROOMS 80-100,

80-103, 80-104 AND 80-124.)

PROVIDE AND INSTALL TWO (2) DUROZONE, EXTERNAL GEAR DRIVEN

CABLE OPERATED DAMPER IN LOCATION SHOWN. PROVIDE TWO (2)

WITH 19'-0" CABLES. VERIFY CABLE LENGTHS. (BALANCING OF SUPPLY

AIR DIFFUSERS IN ROOM 80-101.)

PROVIDE AND INSTALL TWELVE (12) DUROZONE, EXTERNAL GEAR

DRIVEN CABLE OPERATED DAMPER IN LOCATION SHOWN. PROVIDE

FOUR (4) WITH 26'-0" CABLES, THREE (3) WITH 24'-0", THREE (3) WITH

22'-0" CABLES, AND TWO (2) WITH 15'-0" CABLES. VERIFY CABLE
