A. THE FOLLOWING NOTES APPLY EQUALLY TO THE FULL SET OF MECHANICAL DOCUMENTS.

B. REFER TO SHEET M-001 FOR LEGEND, ABBREVIATIONS, AND GENERAL PROJECT NOTES.

C. EXISTING WORK TO REMAIN IS INDICATED WITH LIGHT LINE WEIGHT.

D. COORDINATE ALL SYSTEM OUTAGES WITH OWNER PRIOR TO ALL WORK PER SPECIFICATIONS. PROVIDE AT LEAST 14 DAYS ADVANCE NOTICE TO THE OWNER

FOR ANY UTILITY SHUTDOWNS.

E. REFER TO SPECIFICATIONS FOR ADDITIONAL INFORMATION. REFER TO SCHEDULES, DETAILS, AND DIAGRAMS FOR DUCT, PIPING, EQUIPMENT, AND CONTROL

INFORMATION NOT INDICATED ON FLOOR PLANS.

F. LOCATIONS AND SIZES OF EXISTING DUCTWORK, PIPING AND EQUIPMENT HAVE BEEN DETERMINED FROM A REVIEW OF EXISTING DRAWINGS AND/OR SITE

INVESTIGATIONS WHERE POSSIBLE. ANY DISCREPANCIES BETWEEN EXISTING CONDITIONS AND THE WORK SHOWN ON THE CONTRACT DRAWINGS WHICH MAY IMPACT THE PROGRESS OF THE WORK SHALL BE BROUGHT TO THE ATTENTION OF THE OWNER IN WRITING BEFORE PROCEEDING WITH THE WORK.

G. ALL WORK MUST BE COORDINATED TO MAINTAIN OPERATION OF THE FACILITY.

H. EACH CONTRACTOR SHALL COORDINATE THEIR WORK WITH THE WORK OF OTHERS.

I. COORDINATE ALL MECHANICAL WORK WITH OTHER DISCIPLINES: ARCHITECTURAL, PLUMBING, ELECTRICAL, ETC., SHOWN ON OTHER CONTRACT DOCUMENTS.

J. PROVIDE OFFSETS AND TRANSITIONS AS NECESSARY TO COMPLETE SYSTEMS AND COORDINATE WORK WITH OTHER TRADES.

K. ASBESTOS MAY BE PRESENT. CONTRACTOR SHALL IMMEDIATELY INFORM THE OWNER IN THE EVENT THAT MATERIALS OBSERVED ARE SUSPECTED TO

CONTAIN ASBESTOS. IF LOCATED, ABATE IN ACCORDANCE WITH SPECIFICATIONS AND ICRA PERMIT. REFER TO SPECIFICATIONS 02 82 11 (TRADITIONAL ASBESTOS ABATEMENT) FOR ITEMS REQUIRING ABATEMENT. ASBESTOS ON EXISTING PIPING, DUCT, AND EQUIPMENT SHALL BE REMOVED BACK TO MAIN BY ABATEMENT CONTRACTOR AND NEEDS TO BE RE-INSULATED BY THE MECHANICAL CONTRACTOR. WORK SHALL BE COORDINATED WITH ABATEMENT

CONTRACTOR.

L. ALL WORK SHALL BE IN COMPLIANCE WITH GOVERNING CODES AND OWNER STANDARDS.

M. ALL PENETRATIONS THROUGH FIRE-RATED ASSEMBLIES SHALL BE PROTECTED AND/OR FIRESTOPPED AS REQUIRED TO MAINTAIN FIRE RATINGS. REFER TO

ARCHITECTURAL PLANS FOR LOCATIONS OF FIRE-RATED ASSEMBLIES.

N. WHENEVER NOTES REQUIRE A PRE-TAB ON A SYSTEM, IT SHALL BE PERFORMED BEFORE ANY DEMOLITION OCCURS. MECHANICAL CONTRACTOR SHALL HAVE

BALANCER PERFORM A PRE-TAB TO DETERMINE EXISTING REQUESTED PARAMETER(S) (AIRFLOW, WATERFLOW, STATIC PRESSURE, ETC.), AND BALANCER SHALL SUBMIT A PRE-TAB REPORT WITH RESULTS TO MECHANICAL CONTRACTOR WHO SHALL SUBMIT TO THE OWNER AND ENGINEER. SYSTEM SHALL BE

REBALANCED AS PART OF NEW WORK TO ORIGINAL PARAMETER(S) OBTAINED FROM PRE-TAB.

O. ROOFING CONTRACTOR SHALL MAKE ALL REQUIRED MODIFICATIONS TO THE ROOF TO ACCOMMODATE NEW EQUIPMENT.

P. DURING DEMOLITION OF THE EXISTING HVAC SYSTEMS AND DURING CONSTRUCTION UNTIL NEW HVAC SYSTEM IS OPERATIONAL IN THE WORK AREA, CONTRACTOR SHALL PREVENT FREEZING OF WATER LINES AND OVERHEATING OF ELECTRIC AND IT EQUIPMENT. CONTRACTOR SHALL ALSO MAINTAIN ALL TEMPERATURES LOCATED OUTSIDE OF THE CONSTRUCTION AREA IN SPACES THAT ARE ALSO SERVED BY THE SAME HVAC SYSTEMS. CONTRACTOR SHALL PROPOSE A CONSTRUCTION HVAC PLAN TO THE COR AND HAVE IT APPROVED BEFORE IMPLEMENTATION. THE PLAN MIGHT INCLUDE USE OF THE EXISTING HVAC SYSTEM (CUT DUCT BACK AS DEMOLITION PROGRESSES AND LET IT BLOW IN AREAS), OR CONTRACTOR MIGHT PROVIDE THEIR OWN TEMPORARY HVAC SYSTEMS, OR A COMBINATION OF BOTH MIGHT BE APPROPRIATE AS LONG AS THE PLAN IS REVIEWED AND APPROVED BY THE COR.
