APPLICABLE CODES, ASHRAE, SMACNA, NFPA, EPA, ETC.

2. REFER TO ALL PROJECT DRAWINGS FOR DETAILS OF CONSTRUCTION AND INSTALLATION

REQUIREMENTS.

3. CONTRACTOR SHALL BECOME, PRIOR TO BID, THOROUGHLY FAMILIAR WITH THE

REQUIREMENTS OF THESE NOTES AS WELL AS OTHER NOTES SHOWN ON THE

CONTRACT DOCUMENTS.

4. THESE DRAWINGS REFLECT A SYSTEM DESIGNED AROUND SPECIFIC REFERENCE

PRODUCTS (SEE SCHEDULES). THE SELECTION OF WHICH HAS INFLUENCED THE

DESIGNS OF OTHER TRADES (ELECTRICAL, STRUCTURAL, ETC.). IF SUBSTITUTE

MANUFACTURERS, SIZES, OR MODEL NUMBERS ARE BID, SUBMITTED OR INSTALLED, IT IS

THE RESPONSIBILITY OF THE MECHANICAL CONTRACTOR AND ALL HIS

SUBCONTRACTORS TO COORDINATE ALL DIFFERENCES PRIOR TO BID. ALL COSTS OF

ALL TRADES ASSOCIATED WITH THE SUBSTITUTION SHALL BE INCLUDED IN THE BID.

5. COORDINATION OF ALL MODIFICATIONS TO EACH DISCIPLINE WHICH RESULT FROM

18. ALL HVAC EQUIPMENT TO BE INSTALLED PER MANUFACTURER'S REQUIREMENTS AS

SHOWN. UTILIZE FACTORY FILTERS DURING CONSTRUCTION.

19. ALL PIPING, DUCTS, VENTS, ETC., EXTENDING THROUGH WALLS SHALL BE FLASHED,

COUNTER FLASHED IN WATERPROOF MANNER W/LEAD ROOF JACK.

20. CONTRACTOR TO COORDINATE DUCTWORK WITH OTHER TRADES, OFF-SET AS

REQUIRED, RUN DUCTWORK BETWEEN JOIST WHERE POSSIBLE.

21. CONTRACTOR SHALL VISIT THE JOB SITE & BE FAMILIAR WITH ALL PROJECT CONDITIONS

PRIOR TO FABRICATING ANY EQUIPMENT, DUCTWORK, ETC. NO ALLOWANCES WILL BE

MADE FOR CONTRACTOR UNFAMILIARITY WITH PROJECT CONDITIONS.

22. MECHANICAL CONTRACTOR SHALL BALANCE SYSTEM TO AIR QUANTITIES INDICATED ON

PLANS AND PROVIDE OWNERS REPRESENTATIVES WITH COMPLETE NEBB/AABC

BALANCE REPORT.

23. ALL SQUARE ELBOWS SHALL HAVE TURNING VANES.

24. PROVIDE A MANUAL VOLUME DAMPER AT ALL BRANCH TAKE-OFFS.

25. ALL DUCT DIMENSIONS SHOWN ARE INTERIOR DUCT DIMENSIONS.

26. ALL CONTROL WIRING & CONDUIT SHALL COMPLY WITH NEC.

27. PIPE AND DUCT ROUTING SHOWN IS SCHEMATIC. HVAC CONTRACTOR SHALL PROVIDE

ANY ADDITIONAL OFFSETS AND FITTINGS, INCLUDING DIVIDED DUCTS, REQUIRED FOR

PROPER INSTALLATION AND TO MAINTAIN CLEARANCES AS ENCOUNTERED IN THE FIELD.

28. MECHANICAL CONTRACTOR SHALL COORDINATE WITH ELECTRICAL CONTRACTOR AND

DRAWINGS FOR CONNECTIONS AND LOCATION OF ALL EQUIPMENT.

DEMOLITION GENERAL NOTES:

A. DEMOLITION PLAN HAS BEEN DEVELOPED FROM EXISTING PLANS AND

VISITING SITE. SOME MECHANICAL EQUIPMENT, DUCTWORK, REGISTERS

AND PIPING SIZES MAY NOT BE INDICATED.

B. IT SHALL BE THE RESPONSIBILITY OF ALL CONTRACTORS WHO SUBMIT BIDS

FOR THIS PROJECT TO VISIT THE JOB PREMISES PRIOR TO BIDDING IN

ORDER THAT THEY MAY DETERMINE THE TYPE, QUANTITY, LOCATIONS AND

ANY HARDSHIPS INVOLVED WITH THE REMOVAL OF EQUIPMENT.

C. CONTRACTOR UNDER THIS DIVISION IS FINANCIALLY RESPONSIBLE TO

REPAIR AND PATCH FLOORS, WALLS, CEILING AND ROOF TO MATCH

EXISTING CONDITION WHERE DEMOLITION WORK HAS BEEN DONE.

COORDINATE ALL WORK WITH OWNER/ENGINEER.

D. THE EXISTING HVAC SYSTEM SHALL REMAIN FULLY FUNCTIONAL

THROUGHOUT PHASED CONSTRUCTION.

E. IF THE EXISTING HVAC SYSTEM SHALL EVER REQUIRE SHUTTING DOWN

TEMPORARILY IN OCCUPIED AREAS DURING CONSTRUCTION THE

CONTRACTOR SHALL COORDINATE THE TIMING OF THE SHUT DOWN PERIOD

WITH THE OWNER AND ARCHITECT PRIOR TO DISABLING THE EXISTING

SYSTEM. THE EXISTING HVAC SYSTEM SHALL REMAIN FUNCTIONAL IN ALL

OCCUPIED AREAS DURING NORMAL OPERATION PERIODS.

F. ALL EXISTING THERMOSTATS AND EXISTING CONTROL WIRING SHALL BE

REMOVED FROM ALL EQUIPMENT THAT IS BEING REMOVED IN THE BUILDING

IN DEMOLISHED AREAS UNLESS OTHERWISE NOTED.

SHEET KEYNOTES:

1. EXISTING THERMOSTAT TO BE REMOVED AND

REPLACED WITH NEW THERMOSTAT IN SAME

LOCATION. SEE NEW WORK PLANS FOR MORE

INFORMATION. TYPICAL OF ALL.

SPECIAL NOTES

1. ALL EXISTING HVAC SYSTEMS SHALL REMAIN OPERATIONAL

DURING THIS PROJECT. EXISTING EQUIPMENT SHALL BE

DISABLED ONLY WHEN NEW EQUIPMENT IS ONSITE AND READY

TO BE INSTALLED.

2. AS UNITS ARE INSTALLED, THERMOSTATS SHALL BE INSTALLED

AND PLACED IN STAND ALONE OPERATION MODE.

3. ALL NEW AND EXISTING EQUIPMENT SHALL CONNECT TO NEW

DDC CONTROL SYSTEM TIED INTO THE CONTROL NETWORK.

ALL NEW AND EXISTING EQUIPMENT SHALL RECEIVE NEW DDC

CONTROLLERS FOR COMMUNICATION WITH NEW CONTROL

DEMOLITION GENERAL NOTES:

SHEET KEYNOTES:

1. EXISTING THERMOSTAT TO BE REMOVED AND

REPLACED WITH NEW THERMOSTAT IN SAME

LOCATION. SEE NEW WORK PLANS FOR MORE

INFORMATION. TYPICAL OF ALL.

A. DEMOLITION PLAN HAS BEEN DEVELOPED FROM EXISTING PLANS AND

VISITING SITE. SOME MECHANICAL EQUIPMENT, DUCTWORK, REGISTERS

AND PIPING SIZES MAY NOT BE INDICATED.

B. IT SHALL BE THE RESPONSIBILITY OF ALL CONTRACTORS WHO SUBMIT BIDS

FOR THIS PROJECT TO VISIT THE JOB PREMISES PRIOR TO BIDDING IN

ORDER THAT THEY MAY DETERMINE THE TYPE, QUANTITY, LOCATIONS AND

ANY HARDSHIPS INVOLVED WITH THE REMOVAL OF EQUIPMENT.

C. CONTRACTOR UNDER THIS DIVISION IS FINANCIALLY RESPONSIBLE TO

REPAIR AND PATCH FLOORS, WALLS, CEILING AND ROOF TO MATCH

EXISTING CONDITION WHERE DEMOLITION WORK HAS BEEN DONE.

COORDINATE ALL WORK WITH OWNER/ENGINEER.

D. THE EXISTING HVAC SYSTEM SHALL REMAIN FULLY FUNCTIONAL

THROUGHOUT PHASED CONSTRUCTION.

E. IF THE EXISTING HVAC SYSTEM SHALL EVER REQUIRE SHUTTING DOWN

TEMPORARILY IN OCCUPIED AREAS DURING CONSTRUCTION THE

CONTRACTOR SHALL COORDINATE THE TIMING OF THE SHUT DOWN PERIOD

WITH THE OWNER AND ARCHITECT PRIOR TO DISABLING THE EXISTING

SYSTEM. THE EXISTING HVAC SYSTEM SHALL REMAIN FUNCTIONAL IN ALL

OCCUPIED AREAS DURING NORMAL OPERATION PERIODS.

F. ALL EXISTING THERMOSTATS AND EXISTING CONTROL WIRING SHALL BE

REMOVED FROM ALL EQUIPMENT THAT IS BEING REMOVED IN THE BUILDING

IN DEMOLISHED AREAS UNLESS OTHERWISE NOTED.

SPECIAL NOTES

1. ALL EXISTING HVAC SYSTEMS SHALL REMAIN OPERATIONAL

DURING THIS PROJECT. EXISTING EQUIPMENT SHALL BE

DISABLED ONLY WHEN NEW EQUIPMENT IS ONSITE AND READY

TO BE INSTALLED.

2. AS UNITS ARE INSTALLED, THERMOSTATS SHALL BE INSTALLED

AND PLACED IN STAND ALONE OPERATION MODE.

3. ALL NEW AND EXISTING EQUIPMENT SHALL CONNECT TO NEW

DDC CONTROL SYSTEM TIED INTO THE CONTROL NETWORK.

ALL NEW AND EXISTING EQUIPMENT SHALL RECEIVE NEW DDC

CONTROLLERS FOR COMMUNICATION WITH NEW CONTROL

SYSTEM. REFER TO CONTROLS DRAWINGS FOR FURTHER
