1. UNLESS OTHERWISE NOTED, ALL MECHANICAL EQUIPMENT AND DEVICES ON

WALLS AND CEILING NOT BEING DEMOLISHED ARE EXISTING TO REMAIN UNLESS

REQUIRED BY NEW CONSTRUCTION. COORDINATE WITH VA RESIDENT ENGINEER

ANY ADDITIONAL ITEMS WHICH WILL BE SALVAGED OR ARE TO REMAIN.

2. DEMOLITION WORK IS SHOWN IN DASHED LINES AND HEAVY PENWEIGHT.

EXISTING WORK TO REMAIN IS SHOWN IN SOLID LINE AND LIGHT PENWEIGHT.

3. PROVIDE ALL MECHANICAL DEMOLITION WORK NECESSARY TO INSTALL NEW

WORK. CONTRACTOR SHALL REROUTE AND RECONNECT ANY SYSTEMS THAT

WILL REMAIN IN USE BUT INTERFERES WITH NEW CONSTRUCTION.

4. EXISTING MECHANICAL ITEMS THAT ARE BEING REMOVED AND NOT TO BE

REUSED IN THE NEW CONSTRUCTION SHALL BE DISPOSED OF AS DIRECTED.

REMOVAL AND DISPOSAL OF THE EXISTING ITEMS IS THE CONTRACTORS

RESPONSIBILITY.

5. IF THE CONTINUITY OF MECHANICAL DEVICES AND EQUIPMENT REMOVED IN THE

AREAS OUTSIDE THIS DEMOLITION WORK AREA IS INTERRUPTED, THE

CONTRACTOR SHALL INSTALL REQUIRED DUCTWORK/PIPING TO INSURE THE

CONTINUITY OF SYSTEMS TO EXISTING AREAS OUTSIDE THE DEMOLITION AREAS.

6. DRAWINGS ARE BASED ON EXISTING PLANS AND FIELD INVESTIGATION WITHOUT

DEMOLITION. CONTRACTOR SHALL VISIT EXISTING BUILDING AND FAMILIARIZE

HIM/HER-SELF WITH EXISTING CONDITIONS AND SHALL EXAMINE ALL RELATED

DRAWINGS TO AVOID CONFLICTS. ORIGINAL BUILDING DRAWINGS ARE AVAILABLE.

7. CONTRACTOR TO COORDINATE WITH ARCHITECTURE, ELECTRICAL, PLUMBING

AND OTHER TRADES FOR ALL EQUIPMENT BEING REMOVED. IT IS THE SOLE

RESPONSIBILITY OF THE CONTRACTOR TO COORDINATE ALL MECHANICAL WORK

WITH ALL SUBCONTRACTORS, PRIME CONTRACTOR AND OTHERS WHO MAY BE

PERFORMING DEMOLITION WORK ADJACENT TO OR INTEGRAL TO THE

MECHANICAL WORK.

8. ALL EXISTING ITEMS THAT ARE TO BE REINSTALLED SHALL BE INSPECTED AND

VERIFIED FOR PROPER OPERATION. IF ANY ITEM IS NOT IN A WORKING CONDITION

OR IS DAMAGED, THE ITEM SHALL BE BROUGHT TO THE ATTENTION OF THE VA

RESIDENT ENGINEER FOR DIRECTION.

9. CONTRACTOR SHALL BE RESPONSIBLE FOR ALL CORING, CUTTING, PATCHING,

REPAIRING, REMOVAL, REPLACEMENT, DISCONNECTING, RELOCATIONS,

RECONNECTIONS OF EQUIPMENT AS REQUIRED TO ACCOMMODATE THE

INSTALLATION OF NEW WORK OR REMOVAL.

10. SCHEDULE WORK IN EXISTING BUILDING AT TIMES CONVENIENT TO VA RESIDENT

ENGINEER.

11. INFORM VA RESIDENT ENGINEER IN ADVANCE OF ANY SHUT DOWN THAT WILL

OCCUR AND GIVE ESTIMATE OF DURATION. BEGIN WORK ONLY AFTER

CONTRACTING OFFICER HAS AGREED TO SHUT DOWN.

12. THOROUGHLY INSPECT MECHANICAL SYSTEMS IN REWORKING AREAS AND BRING

TO THE ATTENTION OF THE CONTRACTING OFFICER ALL DEFECTIVE OR

UNSERVICEABLE MATERIAL NOT SCHEDULED FOR REMOVAL OR REPLACEMENT.

13. BEFORE REMOVAL OF EQUIPMENT TO BE RELOCATED, VERIFY PROPER

OPERATION WITH THE VA RESIDENT ENGINEER.

14. NOTIFY VA RESIDENT ENGINEER OF ANY EQUIPMENT DAMAGED OR NOT

OPERATING PROPERLY. THE CONTRACTOR IS RESPONSIBLE FOR PROPER

OPERATION AND CONDITION OF EQUIPMENT AFTER REMOVAL. ANY EQUIPMENT

DAMAGE DUE TO IMPROPER INSTALLATION SHALL BE REPLACED BY THE

CONTRACTOR.

15. REMOVE AND RELOCATE ALL MECHANICAL WORK AS REQUIRED TO PROVIDE

WORK OF OTHER TRADES. PROVIDE ALL MECHANICAL MATERIALS AND LABOR

NECESSARY TO RELOCATE MECHANICAL WORK.

16. ITEMS INDICATED TO BE RETURNED TO THE VA RESIDENT ENGINEER SHALL BE

DELIVERED TO THE LOCATION ON SITE DESIGNATED BY THE VA RESIDENT

ENGINEER.

1. ALL WORK SHALL CONFORM TO FEDERAL, STATE AND LOCAL LAWS, CODES AND

ORDINANCES.

2. THE MECHANICAL DRAWINGS ARE DIAGRAMMATIC ONLY.

3. THE CONTRACTOR IS REQUIRED TO FURNISH ALL LABOR, MATERIAL AND

EQUIPMENT TO COMPLETE THE PROJECT. PROVIDE IN THE SAME OR AS CLOSE TO

THE SAME LOCATION ALL MECHANICAL DEVICES AND EQUIPMENT REMOVED IN

THE DEMOLITION PHASE. WORK SHALL BE PERFORMED BY SKILLED WORKERS IN

THEIR RESPECTIVE TRADES FOLLOWING MANUFACTURERS RECOMMENDATIONS.

4. EXISTING WORK TO REMAIN IS SHOWN IN SOLID LINES AND LIGHT PENWEIGHT.

NEW WORK IS SHOWN IN HEAVY PENWEIGHT.

5. CONTRACTOR TO COORDINATE ARCHITECTURAL, ELECTRICAL, PLUMBING AND

OTHER TRADES FOR ALL EQUIPMENT BEING INSTALLED. IT IS THE SOLE

RESPONSIBILITY OF THE CONTRACTOR TO COORDINATE ALL MECHANICAL WORK

WITH ALL SUBCONTRACTORS, PRIME CONTRACTOR AND OTHERS WHO MAY BE

PERFORMING INSTALLATION WORK ADJACENT TO OR INTEGRAL TO THE

MECHANICAL WORK.

6. WORK REQUIRING SHUT DOWN OF EXISTING SYSTEMS SHALL BE COORDINATED

AND PLANNED WITH THE CONTRACTING OFFICER PRIOR TO THE START OF

CONSTRUCTION.

7. CONTRACTOR SHALL PROVIDE TEST AND BALANCE OF SYSTEMS AFTER WORK IS

COMPLETED. AIRFLOW AND WATER FLOW VALUES SHALL BE RETURNED TO NEW

VALUES WHERE SHOWN ON PLANS AND TO PRE-DEMOLITION RECORDED VALUES

WHERE NEW VALUES ARE NOT SHOWN.

8. THE CONTRACTOR SHALL SEISMICALLY BRACE ALL EXISTING AND NEW NON

STRUCTURAL ELEMENTS FALLING WITHIN RENOVATION “LIMITS OF

CONSTRUCTION” AS REQUIRED BY CODE. REFER TO SPECIFICATION SECTION

130541 (SEISMIC RESTRAINT REQUIREMENTS FOR NON-STRUCTURAL

COMPONENTS) FOR ADDITIONAL INSTRUCTIONS.
