A. ALL NON-WORK AREAS IN THE BUILDING WILL REMAIN OCCUPIED AND OPERATIONAL

DURING THE WORK. USDA WILL VACATE AREAS OF THE BUILDING WHERE WORK IS

BEING PERFORMED. THE CONTRACTOR MUST COORDINATE HIS/HER WORK

ACTIVITIES WITH THE CONTRACTING OFFICER TO AVOID CONFLICTS WITH FACILITY

OPERATIONS. THE CONTRACTOR MUST ERECT BARRIERS AND EMPLOY NECESSARY

MEASURES TO PROTECT PERSONNEL IN THE AREA FROM INJURY.

B. COVER AND PROTECT ALL FURNISHINGS AND EQUIPMENT REMAINING IN THE

SPACES.

C. THE CONTRACTOR MUST PROVIDE BARRIERS AND SIGNAGE TO SECURE THE WORK

AREAS, TO DIRECT PERSONNEL IN WAYFINDING, AND TO ENSURE THE SAFETY OF

D. CONTRACTOR MUST COORDINATE STAGING AREAS WITH USDA PERSONNEL.

E. THE HATCHED “AREA OF WORK” SHOWN ON THE PHASING PLAN INDICATES THE

PRIMARY RENOVATION LIMITS FOR EACH PHASE. WORK REQUIRED BY THE DRAWINGS

AND SPECIFICATIONS MAY EXTEND INTO ADJACENT AREAS OUTSIDE OF THE

HATCHED LIMITS (INCLUDING WORK ABOVE CEILINGS SUCH AS DUCTWORK, PIPING,

AND ASSOCIATED SYSTEMS). WHERE ACCESS IS REQUIRED IN THESE ADJACENT

AREAS, THE CONTRACTOR SHALL REMOVE AND REINSTALL CEILINGS AND FINISHES

AS NECESSARY TO PERFORM THE WORK AND SHALL RESTORE ALL AFFECTED AREAS

TO MATCH EXISTING CONDITIONS. ALL WORK INDICATED IN THE CONTRACT

DOCUMENTS SHALL BE INCLUDED IN THE SCOPE OF THE RESPECTIVE PHASE

REGARDLESS OF WHETHER IT OCCURS STRICTLY WITHIN THE HATCHED AREA.

F. THE CONTRACTOR MUST COMPLETE ALL WORK ASSOCIATED WITH A GIVEN PHASE

PRIOR TO COMMENCEMENT OF WORK IN ANY SUBSEQUENT PHASE. WORK FOR A

NEW PHASE MUST NOT BEGIN UNTIL ALL WORK, TESTING, RESTORATION, AND

ACCEPTANCE REQUIREMENTS OF THE PREVIOUS PHASE ARE COMPLETE (NOTE:

PHASE 2B SEQUENCE 1 MAY BE CONSTRUCTED CONCURRENTLY WITH PHASE 2A.

PHASE 2B SEQUENCE 2 MAY BE CONSTRUCTED CONCURRENTLY WITH PHASE 2B

SEQUENCE 1. PHASE 2B SEQUENCE 2 MUST NOT COMMENCE UNTIL PHASE 2A IS

COMPLETED). THE REQUIRED ORDER OF CONSTRUCTION PHASING MUST BE AS

FOLLOWS:

PHASE 2A → PHASE 2B SEQUENCE 1→ PHASE 2B SEQUENCE 2→ PHASE 3A → PHASE 3B

G. DEVIATION FROM THE ESTABLISHED PHASING SEQUENCE MUST NOT OCCUR

WITHOUT PRIOR WRITTEN APPROVAL FROM THE CONTRACTING OFFICER.

H. CONTRACTOR MUST REMOVE AND RETAIN LIGHT FIXTURES (NOT SHOWN DRAWING)

AS REQUIRED TO ACCOMMODATE THE REMOVAL AND REPLACEMENT OF HYDRONIC

HEATING EQUIPMENT AND PIPING INSULATION AS SHOWN ON THE MECHANICAL

DRAWINGS. CONTRACTOR MUST DISCONNECT AND SAFELY TERMINATE ALL CONDUIT

AND WIRING WITH APPROVED WIRE NUTS AND ELECTRICAL TAPE. FIXTURES MUST BE

PROTECTED FROM DAMAGE AND STORED FOR REINSTALLATION. UPON COMPLETION

OF PIPING AND INSULATION WORK, CONTRACTOR MUST REINSTALL ALL FIXTURES IN

ORIGINAL LOCATIONS AND VERIFY PROPER OPERATION. ANY FIXTURES OR

ASSOCIATED COMPONENTS DAMAGED DURING THIS WORK MUST BE REPAIRED OR

REPLACED IN KIND AT NO COST TO THE GOVERNMENT.

I. PRIOR TO THE START OF WORK EACH DAY IN ACTIVE CONSTRUCTION AREAS, THE

CONTRACTOR MUST TEMPORARILY PROTECT FIRE ALARM INITIATING AND

NOTIFICATION DEVICES AS WELL AS SPRINKLER HEADS (NOT SHOWN ON DRAWING)

FROM DUST, DEBRIS, AND DAMAGE USING APPROVED METHODS. ALL TEMPORARY

COVERINGS MUST BE REMOVED AT THE END OF EACH WORKDAY AND AT ANY TIME

THE FACILITY WILL BE LEFT UNATTENDED FOR MORE THAN FOUR (4) HOURS. FIRE

ALARM DEVICES AND SPRINKLERS IN OCCUPIED AREAS MUST NOT BE COVERED,
