HVAC GENERAL NOTES HVAC DEMOLITION NOTES

HVAC PHASING NOTES

1. THE CONTRACTOR SHALL THOROUGHLY EXAMINE THE SITE PRIOR TO SUBMITTING THEIR BID. DUE TO THE NATURE OF THIS PROJECT AND THE STATE OF THE EXISTING BUILDING, IT IS IMPOSSIBLE TO

COMPLETELY RELATE THE SCOPE OF THE DEMOLITION REQUIRED TO THE CONTRACTOR THROUGH

THE CONTRACT DOCUMENTS. FAILURE TO VISIT THE SITE WILL NOT RELIEVE THE CONTRACTOR OF

THEIR DEMOLITION RESPONSIBILITIES UNDER THIS CONTRACT. IT IS THE CONTRACTOR’S

RESPONSIBILITY TO DETERMINE AND COORDINATE THE EXACT EXTENT OF DEMOLITION NECESSARY TO

PROVIDE A RENOVATED AND UPGRADED SPACE AND TO FACILITATE NEW WORK.

2. INFORMATION REGARDING THE EXISTING CONDITIONS WAS GATHERED FROM AVAILABLE EXISTING DRAWINGS, SURVEY, AND CORRESPONDENCE WITH UTILITY, STAFF, AND FACILITIES PERSONNEL.

THERE ARE NO GUARANTEES AS TO THE ACCURACY OF THIS INFORMATION AND IT IS OFFERED FOR

INFORMATION ONLY.

3. VERIFY EXISTING LOCATIONS OF EQUIPMENT, DUCTWORK, PIPING AND SYSTEM COMPONENTS PRIOR TO DEMOLITION. IF EXISTING CONDITIONS ARE DIFFERENT THAN WHAT IS INDICATED ON THE

CONTRACT DOCUMENTS, THE CONTRACTOR SHALL NOTIFY THE COR AND ARCHITECT PRIOR TO

PROCEEDING WITH THE WORK.

4. MINIMIZE DISTURBANCE AND / OR DAMAGE TO EXISTING FINISHED SURFACES AND FINISHES. WHERE

DEMOLITION OF MECHANICAL SYSTEM COMPONENTS DAMAGES EXISTING SURFACES TO REMAIN,

RESTORE THOSE SURFACES TO THE SAME CONDITION AS THE ADJACENT SURFACES. RESTORATION

MUST BE PERFORMED BY WORKMEN SKILLED IN PERFORMING SUCH WORK. ALL FIRE AND SMOKE

RATINGS SHALL BE RETAINED AS PART OF THE REPAIRS. PATCH / SEAL HOLES WEATHERTIGHT. ALL

PATCHES AND REPAIRS ARE SUBJECT TO THE REVIEW AND APPROVAL OF THE ARCHITECT.

5. ALL AREAS OF EGRESS SHALL BE KEPT OPEN AND FREE FROM DEBRIS AT ALL TIMES.

6. DO NOT REMOVE ITEMS SUPPORTING OTHER ITEMS WITHOUT PROVIDING TEMPORARY OR

PERMANENT SUPPORT. PROPERLY SUPPORT ALL EXISTING ITEMS TO REMAIN. CONTRACTOR SHALL

BE RESPONSIBLE FOR PROVIDING REQUIRED SUPPORTS FOR AFFECTED ITEMS.

7. VERIFY EXTENT OF PIPING, EQUIPMENT, COMPONENTS, AND CONTROLS TO BE RETAINED OR REUSED PRIOR TO THE DEMOLITION OF SPECIFIC SYSTEM. PROTECT ITEMS WHICH ARE TO BE REUSED ON SITE TO MINIMIZE POST-CONSTRUCTION REPAIRS. ALL ITEMS WHICH ARE DAMAGED SHALL BE THE RESPONSIBILITY OF THE CONTRACTOR AND SHALL BE REPAIRED OR REPLACED AT NO COST TO THE

CONTRACT.

8. REFER TO PLANS FOR EXISTING PIPING, DUCTWORK, EQUIPMENT, AND SYSTEM COMPONENTS TO BE

REUSED.

9. THE OWNER RETAINS FIRST RIGHT OF REFUSAL TO ALL EQUIPMENT AND SYSTEM COMPONENTS DEMOLISHED FROM THE PROJECT PRIOR TO DISPOSAL. ALL ITEMS NOT RETAINED BY THE OWNER

SHALL BE PROMPTLY AND PROPERLY DISPOSED OF OR REMOVED FROM SITE.

10. VERIFY ALL EXISTING STRUCTURAL CONDITIONS AND NOTIFY THE STRUCTURAL ENGINEER FOR

APPROVAL TO PENETRATING EXISTING BUILDING STRUCTURAL SYSTEMS.

11. NO DEMOLITION SHALL OCCUR WHICH LEAVES THE BUILDING INTERIOR WITHOUT WEATHER

PROTECTION. ALL DEMOLITION OF EXTERIOR OR EXTERIOR SURFACES SHALL BE FOLLOWED

IMMEDIATELY BY PROTECTIVE CONSTRUCTION. CONTRACTOR SHALL PROVIDE AND INSTALL

TEMPORARY PROTECTION IN ALL OPENINGS WHERE LOUVERS, WINDOWS, OR EXTERIOR DOORS HAVE

BEEN REMOVED.

12. THE DEMOLITION OF THE MECHANICAL SYSTEMS MUST BE PERFORMED TO CORRESPOND TO THE

PHASED NATURE OF THE PROJECT. REFER TO ARCHITECTURAL PHASING PLANS FOR PROJECT

PHASING. THE CONTRACTOR IS RESPONSIBLE FOR ALL TEMPORARY WORK AND EQUIPMENT

NECESSARY TO KEEP REQUIRED SYSTEMS OPERATIONAL UNTIL THEY ARE NO LONGER NEEDED. THIS MAY INCLUDE BUT IS NOT LIMITED TO: RELOCATION OF EQUIPMENT AND ALL APPURTENANCES AND

CONTROLS, RE-PIPING OF EQUIPMENT, AND RE-DUCTING OF EQUIPMENT.

1. THE CONTRACTOR SHALL BE RESPONSIBLE FOR MAINTAINING ALL CONNECTIONS TO EXISTING AND NEW SYSTEMS AS REQUIRED TO FACILITATE PROPER CONTINUAL OPERATION OF ALL SYSTEMS AND EQUIPMENT, EXISTING OR NEW, EXCEPT WHERE IN THE CURRENT PHASE OF CONSTRUCTION.

2. THE CONTRACTOR IS RESPONSIBLE FOR ALL TEMPORARY WORK AND EQUIPMENT NECESSARY TO KEEP REQUIRED SYSTEMS OPERATIONAL UNTIL THEY ARE FULLY RENOVATED AND OPERATING OR UNTIL THEY ARE NO LONGER NEEDED AND DEMOLISHED. THIS MAY INCLUDE BUT IS NOT LIMITED TO: RELOCATION OF EQUIPMENT AND ALL APPURTENANCES AND CONTROLS, RE-PIPING OF EQUIPMENT, AND RE-DUCTING OF

EQUIPMENT.

3. IF THE NEED FOR TEMPORARY SERVICE(S) OR CONNECTIONS DICTATES WORK BE DONE OUT OF PHASE, THIS WORK SHALL BE APPROVED BY THE ARCHITECT AND THE OWNER. WORK SHALL TAKE PLACE IN SUCH A MANNER SO AS NOT TO INTERFERE WITH THE DAY-TO-DAY OPERATIONS OF THE FACILITY AS DETERMINED BY

THE OWNER.

4. REFER TO THE PROJECT SPECIFICATIONS AND ARCHITECTURAL PHASING PLANS TO DETERMINE THE PHASING OF DEMOLITION AND INSTALLATION OF MECHANICAL SYSTEM COMPONENTS. ALTHOUGH PORTIONS OF A MECHANICAL SYSTEM MAY LIE OUTSIDE A PHASED AREA ON PLAN, THOSE COMPONENTS ARE CONSIDERED TO BE “IN PHASE” IF THEIR INSTALLATION AND OPERATION IS REQUIRED FOR THE OCCUPANCY AND USE OF THE PHASED AREA. ALL “IN PHASE” MECHANICAL COMPONENTS SHALL BE INSTALLED AND MADE OPERATIONAL PRIOR TO THE COMPLETION OF THAT PHASE. COORDINATE ALL PHASING REQUIREMENTS WITH

THE GENERAL CONTRACTOR’S SCHEDULE TO ENSURE CONTINUITY OF SYSTEM OPERATION.

5. THE CONTRACTOR SHALL BE AWARE THAT THE EXISTING BUILDING(S) AND ADJACENT SITE WILL BE OCCUPIED AND IN USE 24 HOURS PER DAY, 7 DAYS A WEEK. THE CONTRACTOR SHALL CONDUCT THEIR OPERATIONS SO THAT THERE WILL BE MINIMAL INTERFERENCE WITH THE CONTINUED OPERATION OF THE EXISTING BUILDING(S) AND STAFF. ANY INTERFERENCE OR INCONVENIENCE TO BUILDING OPERATIONS SHALL

BE REVIEWED WITH THE COR AND ARCHITECT PRIOR TO COMMENCEMENT.

6. CONTRACTOR SHALL MINIMIZE SHUTDOWN TIMES DURING MECHANICAL SYSTEM SWITCHOVERS. ALL

SHUTDOWN TIMES AND THEIR DURATIONS SHALL BE COORDINATED WITH THE COR.
