GENERAL NOTES

1. ALL PIPING AND DUCTS IN FINISHED ROOMS OR SPACES SHALL BE CONCEALED IN A FURRED CHASE

OR ABOVE THE HARD SUSPENDED CEILING.

2. THE FIRST FIGURE OF DUCT SIZE INDICATES DIMENSION OF FACE SHOWN OR INDICATED. DUCT SIZES

ARE NET INSIDE DIMENSIONS.

3. ACCESS PANELS IN HARD SUSPENDED CEILINGS ARE REQUIRED FOR ALL VALVES, TRAPS, DAMPERS, CLEANOUTS, CONTROLS, ETC. ACCESS PANELS SHALL BE FURNISHED AND INSTALLED UNDER THE

ARCHITECTURAL SPECIFICATIONS.

4. TOTAL STATIC PRESSURE NOTED IN THE SCHEDULES INCLUDES DUCT SYSTEM, TERMINAL UNITS, FILTERS, COILS, ETC.

5. FOR TYPICAL STEAM AND WATER PIPING CONNECTIONS TO EQUIPMENT, SEE STANDARD EQUIPMENT

DETAILS.

6. DIFFUSER, REGISTER AND GRILLE SIZES SHOWN ON FLOOR PLANS ARE NECK SIZES.

7. REFER TO ARCHITECTURAL REFLECTED CEILING PLANS FOR EXACT LOCATIONS OF CEILING

DIFFUSERS, REGISTERS, AND GRILLES.

8. SEISMIC PROVISIONS NOT REQUIRED. ALL PRESSURES LISTED ARE GAGE PRESSURE UNLESS

OTHERWISE NOTED.

9. FIELD COORDINATE ALL PIPE AND DUCT RUNS BEFORE FABRICATION AND INSTALLATION. NO EXTRAS SHALL BE PERMITTED FOR REROUTING, REFABRICATION, RESTOCKING OR REMOVAL OF INSTALLED WORK DUE TO COORDINATION WITH BUILDING STRUCTURE, WORK OF OTHER TRADES OR EXISTING BUILDING COMPONENTS. DRAWINGS ARE SCHEMATIC AND DO NOT SHOW ALL NECESSARY CHANGES IN ELEVATION OR OFFSETS REQUIRED FOR A COMPLETE INSTALLATION. PROVIDE ALL DUCT AND

PIPE OFFSETS AS REQUIRED.

DEMOLITION NOTES:

1. REFER TO THE ARCHITECTURAL DRAWINGS FOR THE EXTENT OF THE

DEMOLITION SCOPE OF WORK AND AREA. THE DEMOLITION PLANS INDICATE

THE GENERAL INTENT AND ARE NOT INTENDED TO SHALL ALL ITEMS TO BE

REMOVED OR RETAINED.

2. VISIT THE SITE PRIOR TO SUBMISSION OF THE BIDS TO BECOME FAMILIAR WITH

THE ACTUAL CONDITIONS AND EXTENT OF THE WORK.

3. TRACE AND LABEL ALL EXISTING SYSTEMS WITHIN THE DEMOLITION AREA AND

BEYOND PRIOR TO DISCONNECTION AND REMOVAL TO ENSURE THAT NO AREA

OUTSIDE THE DEMOLITION AREA IS AFFECTED. REVIEW IN DETAIL WITH THE

GENERAL CONTRACTOR AND OWNER WHAT IS TO BE REMOVED AND REMAIN

PRIOR TO WORK COMMENCING. THERE SHALL BE NO INTERRUPTION OF

SERVICES OUTSIDE THE DEMOLITION AREA WITHOUT APPROVAL FROM THE

OWNERS REPRESENTATIVE.

4. NOTIFY THE OWNER'S REPRESENTATIVE IMMEDIATELY OF ANY UNANTICIPATED

HIDDEN CONDITIONS ENCOUNTERED DURING THE DEMOLITION.

5. ALL ITEMS REMOVED SHALL BE OFFERED TO THE OWNER FOR SALVAGE. IF THE

OWNER DOES NOT TAKE POSSESSION, DISPOSE OF ITEMS IN A SAFE AND

LEGAL MANNER. ALL ITEMS CLASSIFIED AS HAZARDOUS SHALL BE DISPOSED AS

HAZARDOUS WASTES AND A UNIFORM HAZARDOUS WASTE MANIFEST SHALL BE

PROVIDED TO THE OWNER.

6. NOTIFY UTILITY COMPANIES IN ACCORDANCE WITH THEIR REQUIREMENTS

PRIOR TO DEMOLITION VERIFY THAT THE UTILITIES HAVE BEEN

DISCONNECTED, VALVED, CAPPED AND MADE SAFE PRIOR TO DEMOLITION.

7. ENSURE THE SAFE PASSAGE OF PERSONS IN AND AROUND THE BUILDING

DURING DEMOLITION. PREVENT INJURY TO PERSONS AND DAMAGE TO

PROPERTY. PROVIDE ADEQUATE SHORING AND BRACING TO PREVENT

COLLAPSE. IMMEDIATELY REPAIR DAMAGED PROPERTY TO THE CONDITION

BEFORE BEING DAMAGED. TAKE EFFECTIVE MEASURES TO PREVENT

WINDBLOWN DUST.

8. DO NOT USE CUTTING TORCHES UNTIL WORK AREA IS CLEARED OF

FLAMMABLE MATERIALS AT CONCEALED SPACES, SUCH AS PIPE INTERIORS OR

SHAFTS. VERIFY CONDITION AND CONTENTS OF HIDDEN SPACE BEFORE

STARTING FLAME CUTTING OPERATIONS. MAINTAIN FIRE WATCH AND

PORTABLE FIRE-SUPPRESSION DEVICES DURING FLAME CUTTING OPERATIONS.

MAINTAIN ADEQUATE VENTILATION WHEN USING CUTTING TORCHES.

9. DRAIN, PURGE, OR OTHERWISE REMOVE, COLLECT AND DISPOSE OF

CHEMICALS, LIQUIDS, GASES, EXPLOSIVES, ACIDS, FLAMMABLES OR OTHER

DANGEROUS MATERIALS BEFORE PROCEEDING.

10. PROPERLY LABEL ALL UNLABELED PIPES THAT REMAIN WITH COLOR PIPE

MARKERS.

11. ALL DEMOLITION SCOPE ASSOCIATED WITH LOW VOLTAGE WIRING FOR

CONTROLS AND ASSOCIATED INTERLOCKS SHALL BE INCLUDED IN THIS

CONTRACT.

12. ALL EQUIPMENT LOCATIONS AND PIPE AND DUCTWORK SIZES INDICATED ARE

APPROXIMATE. VERIFY EXACT LOCATIONS AND SIZES IN THE FIELD.

13. REFER TO THE MECHANICAL DRAWINGS FOR THE FULL EXTENT OF THE SCOPE

OF DEMOLITION. DISCONNECT AND MAKE SAFE ALL MECHANICAL EQUIPMENT

IDENTIFIED FOR REMOVAL ON THE MECHANICAL DEMOLITION PLANS. THE

MECHANICAL SCOPE MAY EXTEND BEYOND THE AREA DEFINED BY THESE

WORK SCOPE LIMITS TO FULLY COMPLY WITH THE VARIOUS REQUIREMENTS

DEIFNED BY THESE NOTES.

14. THE HVAC DEMOLITION PLANS INDICATE GENERAL INTENT AND ARE NOT

INTENDED TO SHOW ALL COMPONENTS AND ITEMS TO BE REMOVED OR

RETAINED. THE HVAC, ATC, & TAB CONTRACTORS SHALL VISIT THE SITE PRIOR

TO SUBMISSION OF THEIR BIDS TO BECOME FAMILIAR WITH THE ACTUAL

WORKING CONDITIONS AND THE EXTENT OF WORK. EQUIPMENT AND

CONTROLS DESIGNATED TO BE REMOVED SHALL BE DISCONNECTED AND MADE

SAFE. THE HVAC, ATC, & TAB CONTRACTORS SHALL IMMEDIATELY NOTIFY THE

GENERAL CONTRACTOR AND THE OWNERS REPRESENTATIVE OF ANY

UNANTICIAPTED OR HIDDEN CONDITIONS ENCOUNTERED DURING DEMOLITION.

15. THE MECHANICAL CONTRACTOR SHALL BE RESPONSIBLE FOR THE REPAIR OF

ALL SYSTEMS OR BUILDING COMPONENTS DAMGED BY HIM AS A RESULT OF

CONSTRUCTION DURING THE EXECUTION OF THE WORK. DAMAGE SHALL

INCLUDE, BUT NOT BE LIMITED TO, THE DESTRUCTION OR DISPOSAL OF ITEMS

INTENDED TO REMAIN OR BE SALVAGED.

16. THE MECHANICAL CONTRACTOR SHALL SYSTEM TRACE AND LABEL ALL

EXISTING BRANCH SUSTEMS AND MAINS WITHIN OR ASSOCIATED WITH THE

DEMOLITION SCOPE, PRIOR TO DEMOLITION AND DISCONNECTION. ALL

SYSTEMS IDENTIFIED FOR REMOVAL SHALL BE TRACED AND FIELD LABELED TO

ENSURE THAT NO AREA OUTSIDE THE DEMOLITION SCOPE LIMIT IS AFFECTED.

17. IN ANY AREA REQUIRING THE PERFORMANCE OF ANY OTHER TRADE'S WORK,
