UNDER THIS CONTRACT SHALL REMAIN THE PROPERTY OF

THE OWNER. CONTRACTOR SHALL SUBMIT A LIST OF

EQUIPMENT TO BE REMOVED TO THE OWNER.

CONTRACTOR SHALL RETAIN OR DISPOSE OF MATERIALS

AND EQUIPMENT AS DIRECTED BY THE OWNER.

2. ALL EQUIPMENT SHALL BE REMOVED IN A CAREFULLY

PLANNED MANNER. ALL CEILING-HUNG EQUIPMENT SHALL

BE REMOVED BY PROVIDING SUPPORTS FROM BELOW. NO

DROPPING OF EXISTING EQUIPMENT ONTO THE FLOOR

SLAB WILL BE ALLOWED.

3. REMOVE CONTROL WIRING OR PNEUMATIC TUBING

ASSOCIATED WITH EQUIPMENT BEING REMOVED,

COORDINATE WITH ELECTRICAL CONTRACTOR AS

REQUIRED. THE REMOVAL OF CONTROL APPARATUS SHALL

NOT INTERFERE WITH NORMAL OPERATION OF REMAINING

EQUIPMENT OR SYSTEMS.

4. REMOVE ALL CHILLED WATER SUPPLY AND RETURN PIPING

AND VALVES.

5. NOT ALL HVAC EQUIPMENT, DUCTWORK, PIPING, AND/OR

OTHER PIPING SYSTEMS ARE SHOWN ON THESE

DEMOLITION DRAWINGS. CONTRACTOR SHALL IDENTIFY ALL

DUCTS AND PIPES PRIOR TO DEMOLITION.

6. SIZES OF PIPING AND DUCTWORK TO BE REMOVED AND/OR

REMAIN MAY NOT HAVE BEEN INDICATED. CONTRACTOR

SHALL SURVEY EXISTING SPACE, VERIFY SIZES, AND

INCLUDE IN SCOPE OF WORK. DISCREPANCIES DISCOVERED

BETWEEN FIELD CONDITIONS AND CONSTRUCTION

DOCUMENTS SHALL BE REPORTED TO THE ENGINEER

PROMPTLY.

7. NO PIPING SHALL BE REMOVED UNLESS BRANCH SHUTOFF

VALVES ARE IDENTIFIED AND CLOSED PRIOR TO ACTUAL

REMOVAL.

8. DRAIN ALL PIPING SECTIONS TO BE REMOVED PRIOR TO

ACTUAL REMOVAL. NO SPILLING OVER FLOOR SLABS

SHALL BE PERMITTED. DRAIN PIPES INTO PORTABLE

CONTAINERS TO BE DISPOSED OF AS REQUIRED.

9. PROVIDE TEMPORARY SHEET METAL CAP ON ALL OPEN

END DUCTWORK THAT IS TO REMAIN.

10. ALL SERVICES PASSING THROUGH DEMOLITION CONTRACT

AREA SERVING OTHER AREAS SHALL REMAIN AND SHALL

BE PROTECTED UNLESS OTHERWISE NOTED.

11. CONSIDER USING A NEGATIVE PRESSURE MACHINE:

MAINTAIN DEMOLITION/CONSTRUCTION AREA AT A

NEGATIVE PRESSURE RELATIVE TO THE ADJOINING NON-

WORK AREAS IN ORDER TO LIMIT THE SPREAD OF

AIRBORNE CONTAMINATION. PROVIDE A TEMPORARY HEPA-

FILTERED NEGATIVE AIR FAN FOR CONSTRUCTION AREA.

MAINTAIN A 0.05” NEGATIVE PRESSURE IN THE

CONSTRUCTION AREA RELATIVE TO THE ADJACENT

SPACES. PROVIDE ADDITIONAL NEGATIVE AIR MACHINES AS

REQUIRED TO ACHIEVE MINIMUM NEGATIVE PRESSURE.

PROVIDE WELL-SEALED TEMPORARY DUCT BARRIER

PARTITIONS. ALL EXISTING RETURN REGISTERS LOCATED

WITHIN THE RENOVATION AREA SHALL BE BLANKED OFF.

TEMPORARILY REDUCE SUPPLY CFM TO MAINTAIN0.05”

NEGATIVE PRESSURE. ROUTE TEMPORARY FLEXIBLE DUCT

FROM DISCHARGE OF HEPA UNIT TO OUTSIDE OF

TEMPORARY BARRIER. LOCATE EXHAUST FAN DISCHARGE

MINIMUM 25’-0” FROM OPERABLE WINDOWS AND OUTSIDE

AIR INTAKES. FAN CRITERIA: MANUFACTURED BY ‘HEPA-

AIRE’, MODEL -1800 PAS VARIABLE CFM, 1000 TO 1800 CFM,

115V/60HZ, 10 FLA.

12. IN CONJUNCTION WITH ABOVE NEGATIVE PRESSURE

REQUIREMENT, PROVIDE AN INCLINED MANOMETER,

DIFFERENTIAL PRESSURE TYPE, WITH WHITE FACE GAUGE

AND BLACK LETTERS. THIS SHALL BE USED BY THE

CONTRACTOR TO RECORD, ON A DAILY BASIS, THE

NEGATIVE PRESSURE IN THE RENOVATION AREA RELATIVE

TO THE ADJACENT SPACES.

GENERAL NOTES

1. THE CONTRACTOR SHALL VISIT AND CAREFULLY EXAMINE THOSE

PORTIONS OF THE BUILDING AND SITE AFFECTED BY THIS WORK

BEFORE SUBMITTING PROPOSAL SO AS TO BECOME FAMILIAR

WITH EXISTING WORK. SUBMISSION OF A PROPOSAL WILL BE

CONSTRUED AS EVIDENCE THAT SUCH EXAMINATION HAS BEEN

MADE AND LATER CLAIMS FOR LABOR, EQUIPMENT OR MATERIALS

REQUIRED BECAUSE OF DIFFICULTIES ENCOUNTERED WILL NOT BE

RECOGNIZED. IT IS TO BE UNDERSTOOD THAT UNFORESEEN

CONDITIONS PROBABLY EXIST AND NEW WORK MAY NOT BE FIELD

LOCATED EXACTLY AS SHOWN ON THE DRAWINGS. COOPERATION

WITH OTHER TRADES IN EQUIPMENT ROUTING AS DETERMINED

DURING CONSTRUCTION AND AS DIRECTED BY THE

ARCHITECT/ENGINEER MAY BE NECESSARY AND IT IS INTENDED

THAT SUCH DEVIATIONS SHALL BE CONSIDERED AS PART OF THIS

CONTRACT. IT IS ALSO UNDERSTOOD THAT THE PLANS ARE NOT

COMPLETELY TO SCALE. THIS CONTRACTOR IS TO FIELD VERIFY

DIMENSIONS OF ALL EXISTING CONDITIONS, PRIOR TO BID AND

INCLUDE ANY DEVIATIONS IN THE CONTRACT.
