A.ALL PIPING AND DUCTS IN FINISHED ROOMS OR SPACES SHALL BE

CONCEALED IN FURRED CHASES OR SUSPENDED CEILINGS,

UNLESS OTHERWISE NOTED.

B.PROVIDE ACCESS PANELS OR DOORS IN INACCESSIBLE CEILINGS

AND/OR CHASES FOR ALL VALVES, TRAPS, DAMPERS,

CLEANOUTS, COILS, FANS, CONTROLS, ETC. ACCESS DOOR

RATING SHALL MATCH CLASSIFICATION OF WALL AND CEILING

FIRE RATING.

C.COORDINATE THE LOCATION OF ALL DIFFUSERS, GRILLES,

REGISTERS, ACCESS DOORS, ETC., WITH THE ARCHITECTURAL

REFLECTED CEILING PLAN(S).

D. ALL ROUND RUN OUTS AND DROPS TO DIFFUSERS SHALL BE THE

SAME NOMINAL SIZE AS THE SCHEDULED DIFFUSER NECK SIZE.

E. THE FIRST FIGURE OF DUCT SIZE INDICATES DIMENSION OF FACE

SHOWN OR INDICATED. ALL DUCT SIZES SHOWN ON DRAWINGS

OF U.L. APPROVED FIRE PROOF CAULKING MATERIAL.

I. CONTRACTOR SHALL COORDINATE ALL DUCTWORK, PIPING.

PLUMBING AND FIRE PROTECTION PIPING WITH STRUCTURAL AND

ELECTRICAL SYSTEMS AND SHALL PROVIDE NECESSARY

OFFSETS TO AVOID CONFLICTS AND TO MAINTAIN EQUIPMENT

ACCESS AND SERVICEABILITY.

J. CONTRACTOR SHALL FURNISH ALL NECESSARY STRUCTURES,

INSERTS, SLEEVES, AND HANGING DEVICES FOR INSTALLATION

OF MECHANICAL AND PLUMBING EQUIPMENT, DUCTWORK AND

PIPING. ETC. CONTRACTOR SHALL COORDINATE WITH GENERAL

CONTRACTOR AND ALL BUILDING TRADES TO AVOID CONFLICTS

AND TO MAINTAIN EQUIPMENT ACCESS AND SERVICEABILITY.

K. CONTRACTOR SHALL BE RESPONSIBLE FOR PROVIDING ALL

NECESSARY MISCELLANEOUS ANGLES, CHANNELS. UNISTRUT,

ETC., AS MAYBE REQUIRED TO ADEQUATELY SUPPORT THE

MECHANICAL PIPING. DUCTWORK, AND EQUIPMENT IN A MANNER

APPROVED BY THE ARCHITECT WHICH WILL NOT OVERLOAD THE

BUILDING STRUCTURAL SYSTEM.

L. SEAL ALL TRANSVERSE JOINTS, LONGITUDINAL SEAMS,

DUCTWALL PENETRATIONS AND FITTING CONNECTIONS ON ALL

DUCT SYSTEMS.

M.CONTRACTOR SHALL BE RESPONSIBLE FOR PROVIDING ANY

TEMPORARY HVAC AS REQUIRED DURING CONSTRUCTION TO

MINIMIZE SHUT DOWNS.
