KEYNOTES

EXISTING DUAL DUCT VAV BOX AND ASSOCIATED PNEUMATIC CONTROL TUBING TO BE REMOVED

ENTIRELY. CONTRACTOR SHALL FIELD VERIFY EXACT LOCATION OF BOX PRIOR TO BEGINNING

ANY WORK. CONTRACTOR SHALL FIELD VERIFY EXACT LOCATION OF EXISTING ASSOCIATED

THERMOSTAT AND REMOVE ENTIRELY. PREPARE DUCT AS NECESSARY TO ACCEPT THE

INSTALLATION OF THE NEW DUAL DUCT VAV BOX. SEE NEW WORK PLAN FOR ADDITIONAL

REQUIREMENTS.

CONTRACTOR SHALL REMOVE CEILING TILES AND GRID OR GYPSUM CEILING AS NECESSARY TO

ALLOW FOR THE REMOVAL OF THE EXISTING DUAL DUCT VAV BOX AND THE INSTALLATION OF THE

NEW DUAL DUCT VAV BOX. ONCE NEW BOX HAS BEEN INSTALLED, THE CONTRACTOR SHALL

REINSTALL THE CEILING GRID AND TILES, OR MAKE REPAIRS TO THE GYPSUM CEILING TO MATCH

IMMEDIATE SURROUNDING. IT IS EXPECTED FOR THE CEILING TO HAVE THE SAME ORIGINAL

PAINTED FINISH ONCE THE WORK IS COMPLETE.

CONTRACTOR SHALL FIELD VERIFY THE EXACT LOCATION OF THE EXISTING THERMOSTAT PRIOR

TO BEGINNING ANY WORK. THERMOSTAT SHALL BE REMOVED ENTIRELY WHEN VAV BOX IS

REMOVED. SEE NEW WORK PLAN FOR ADDITIONAL REQUIREMENTS.

EXISTING CHILLED WATER WATER AIR HANDLING UNIT (AHU-3) TO REMAIN. EXISTING PNEUMATIC

CHILLED WATER CONTROL VALVE TO BE REMOVED AND REPLACED NEW WITH DDC CONTROLLED

VALVE. REFERENCE NEW WORK PLAN FOR ADDITIONAL INFORMATION. CHILLED WATER PIPING

SHALL REMAIN. MODIFY PIPING AS NECESSARY TO ACCOMMODATE NEW CONTROL VALVE. THIS

WORK IS PART OF THE BASE BID.

NOTE:

EXISTING DUCT, VAV BOX, AND THERMOSTAT

LOCATIONS AND SIZES WERE OBTAINED FROM

THE ORIGINAL BUILDING PLANS FROM 1966 PLUS

SEVERAL SUBSEQUENT RENOVATIONS. THE

CONTRACTOR SHALL FIELD VERIFY ALL EXISTING

LOCATIONS AND SIZES PRIOR TO BID AND

BEGINNING ANY WORK. EQUIPMENT LOCATIONS

SHOWN ON THE PLANS ARE APPROXIMATE. FIELD

VERIFY ALL DUCT SIZES AND LOCATIONS OF HOT

DECK AND COLD DECK INLETS ON THE DUAL

DUCT BOXES. BOXES SHALL BE ORDERED TO

MATCH EXISTING CONNECTION

CONFIGURATIONS. TRANSITION EXISTING DUCT

AS NECESSARY FOR CONNECTIONS TO NEW VAV

BOX INLETS AND OUTLETS.

COORDINATION OF WORK IN EACH AREA SHALL

BE MADE A MINIMUM OF 10 DAYS IN ADVANCE OF

WORK OCCURRING WITH THE ASPA PM.

DEMOLITION AND INSTALLATION OF NEW VAV BOX

SHALL OCCUR CONSECUTIVELY. REMOVAL OF

EXISTING BOX SHALL ONLY OCCUR WHEN NEW

BOX IS AVAILABLE AND READY FOR

INSTALLATION. AREAS OF WORK SHALL BE KEPT

TO A MINIMUM TO PREVENT EXCESSIVE

DISRUPTION TO ONGOING BUSINESS

OPERATIONS AT THE FACILITY. WORK AREAS

SHALL BE CLEANED DAILY BEFORE THE NEXT

BUSINESS DAY.
