THE MECHANICAL SYSTEM HAS BEEN DESIGNED IN ACCORDANCE WITH THE 2012 VIRGINIA UNIFORMSTATEWIDE BUILDING CODE.

COORDINATE LOCATION OF ALL DUCTWORK, SUPPLY AND RETURN DEVICES, EXHAUST FANS,THERMOSTATS AND OTHER WALL OR CEILING MOUNTED EQUIPMENT WITH REFLECTED PLANS, LIGHTFIXTURES, SPRINKLER SYSTEMS AND ACCESSORIES INSTALLED BY OTHER TRADES SO AS TO PRESENTA NEAT AND ATTRACTIVE INSTALLATION THROUGHOUT THE BUILDING.

ALL DUCTWORK SHALL BE CONCEALED UNLESS OTHERWISE NOTED.

ARRANGE DUCTWORK PARTICULARLY ABOVE CEILING AS REQUIRED TO CLEAR STRUCTURE, CONDUIT,LIGHTS, ETC., ALLOWING SPACE FOR HANGERS, INSULATION, ETC.

DUCT SIZES SHOWN ARE INSIDE FREE AREA DIMENSIONS.

REFER TO ARCHITECTURAL DRAWINGS AND LIFE SAFETY PLANS FOR ALL RATED CONDITIONS.

MAINTAIN PROPER CLEARANCES PER ELECTRICAL CODE ON ALL VAV BOXES AND OTHER EQUIPMENT.COORDINATE WITH ALL TRADES TO ENSURE CLEARANCES ARE NOT OBSTRUCTED.

INSTALL ALL VAV BOXES BETWEEN 6 INCHES MINIMUM AND 24 INCHES MAXIMUM ABOVE CEILING.

FINAL LOCATION OF SPACE THERMOSTATS AND SENSORS SHALL BE APPROVED BY ARCHITECT.

INSTALL ALL WALL MOUNTED NON-ADJUSTABLE SENSORS AT 5'-0" FROM FINISHED FLOOR TO TOP OFSENSOR. ADJUSTABLE DEVICE SHALL BE INSTALLED 4'-0' ABOVE FINISHED FLOOR.

ALL ROUND BRANCH DUCTS TO DIFFUSERS SHALL MATCH NECK SIZES SHOWN ON SCHEDULE, UNLESSOTHERWISE NOTED.

ALL DIFFUSERS, GRILLES AND REGISTERS SHALL BE SIZED TO HAVE A MINIMUM FREE AREA OF 70% ANDMEET PERFORMANCE CRITERIA SCHEDULED.

PROVIDE A CONTINUOUS RETURN AIR PATH FROM SPACE CEILING RETURN PLENUMS TO THEIRASSOCIATED ROOFTOP UNIT. IN SPACES HAVING WALLS THAT ARE CONTINUOUS TO DECK, AND FORWHICH NO TRANSFER DUCT HAS BEEN INDICATED, PROVIDE SLEEVED WALL OPENING WITH TRANSFER"L" DUCT SIZED AT 500 FPM.

INDICATED MANUFACTURER'S ARE FOR BASIS OF DESIGN ONLY. ALTERNATE MANUFACTURER'S AREALLOWED AS APPROVED.
