BUILDING LOCATION: 21200 CAMPUS DRIVE

STERLING, VA 20164

PROJECT DESCRIPTION:

THIS PROJECT WILL PROVIDE THE SPECIFICATION AND INSTALLATION OF A NEW

MEDICAL OXYGEN GENERATOR SYSTEM FOR THE LA BUILDING. NEW OXYGEN

GENERATOR WILL CONNECT TO THE EXISTING MEDICAL GAS SYSTEM IN ROOM

127A. NEW OXYGEN GENERATOR WILL BE LOCATED IN ROOM 127A.

HIGH PERFORMANCE BUILDINGS ACT NOTICE:

IN ACCORD WITH THE HIGH PERFORMANCE BUIDLING ACT, THE BUILDINGS ARE

EXEMPT FROM COMPLIANCE BECAUSE THE COST OF THE RENOVATIONS DOES

NOT EXCEED 50% OF THE VALUE OF EACH BUILDING.

ASBESTOS COMPLIANCE STATEMENT (ALL BUILDINGS):

AN ASBESTOS INSPECTION WAS NOT PERFORMED BECAUSE ALL PORTIONS OF

THE EXISTING BUILDING THAT MAY BE AFFECTED BY THE WORK WERE

ORIGINALLY CONSTRUCTED AFTER JANUARY 1, 1985.

NO ASBESTOS CONTAINING MATERIALS TO BE USED IN THIS PROJECT

LEAD COMPLIANCE STATEMENT (ALL BUILDINGS):

AN INSPECTION TO IDENTIFY LEAD CONTAINING OR COATED BUILDING

COMPONENTS HAS NOT BEEN CONDUCTED BECAUSE THE BUILDING WAS

CONSTRUCTED AFTER JANUARY 1, 1985 AND THE OWNER HAS NO KNOWLEDGE

OF LEAD CONTAINING OR COATED BUILDING COMPONENTS IN THE BUILDING. IT

IS THE CONTRACTOR’S RESPONSIBILITY TO COMPLY WITH ALL VIRGINIA

OCCUPATIONAL SAFETY AND HEALTH (VOSH) REGULATIONS AS THEY PERTAIN

TO EMPLOYEE EXPOSURES TO LEAD. ALL LEAD AND LEAD-COATED BUILDING

COMPONENTS SHALL BE RECYCLED TO THE EXTENT POSSIBLE

PROJECT FIRE STOPPING REQUIREMENTS:

SEAL ALL PIPE PENETRATIONS IN FIRE RATED CONSTRUCTION WITH FACTORY BUILT DEVICES

OR WITH MANUFACTURED FILL, VOID OR CAVITY MATERIALS “CLASSIFIED” BY UNDERWRITERS

LABORATORIES, INC. FOR USE AS A THROUGH PENETRATION FIRESTOP. ALL FIRESTOP

DEVICES AND SYSTEMS SHALL BE APPROVED BY THE OWNER. THE FIRESTOP SYSTEM USED

SHALL MAINTAIN THE FIRE RESISTANCE RATING OF THE BUILDING COMPONENT THAT IS

PENETRATED. FIRESTOP SYSTEMS AND DEVICES SHALL COMPLY WITH ASTM E 814 (UL 1479)

FOR ALL TYPES OF PENETRATIONS BEING SEALED. SUBMITTAL DATA FOR FIRESTOP SYSTEMS

SHALL INCLUDE THE APPLICABLE UL SYSTEM NUMBERS. EXCESSIVE SHRINKAGE OF THE

FIRESTOP MATERIALS, WHICH WOULD PERMIT THE TRANSMISSION OF SMOKE OR WATER PRIOR

TO EXPOSURE TO A FIRE CONDITION, IS UNACCEPTABLE. FIRESTOP SHALL NOT PERMIT

CRACKS AND SHALL BE WATERPROOF. WHERE A MASTIC COATING IS USED TO SEAL THE

SURFACE OF THE FIRESTOP, THE MASTIC SHALL BE NON-HARDENING. THE FIRESTOP SYSTEM

USED SHALL ACCOMMODATE EXPANSION AND CONTRACTION OF THE FLOATING MECHANICAL

PIPING SYSTEMS WITHOUT DAMAGING THE FIRESTOP OR REDUCING ITS EFFECTIVENESS AS A

SMOKE BARRIER OR WATER SEAL. THE FIRESTOP MANUFACTURER'S REPRESENTATIVES SHALL

INSTRUCT THE SUBCONTRACTOR'S REPRESENTATIVES IN THE PROPER INSTALLATION

PROCEDURES SO THAT THE PENETRATIONS ON THE PROJECT WILL BE INSTALLED IN

ACCORDANCE WITH THE UL LISTING AND THE MANUFACTURER'S RECOMMENDATIONS. IF IT

COMPLIES WITH THESE SPECIFICATIONS, FIRESTOP SEALING COMPONENT/SYSTEM AS

MANUFACTURED BY ONE OF THE FOLLOWING MANUFACTURERS WILL BE ACCEPTABLE:

1. TREMCO FIRE RESISTIVE JOINT SYSTEM USING DYMERIC SEALANT AND

CERABLANKET-FS MINERAL FILLER.

2. SPECIFIED TECHNOLOGIES, INC. SPECSEAL SYSTEMS.

3. 3M FIRE BARRIER PENETRATION SEALING SYSTEMS.

4. GE PENSIL FIRESTOP SEALANT BY GENERAL ELECTRIC.

5. INTERNATIONAL PROTECTIVE COATINGS CORP. FLAME SAFE SYSTEMS.

6. THERMAL CERAMICS FIRE MASTER FIRESTOP FIRE PROTECTION SYSTEMS.

7. HILTI FS-601 SYSTEMS.

ALL UNUSED SLEEVES SHALL BE SEALED WITH FIRESTOP DEVICES AND SYSTEMS TO MAINTAIN

THE FIRE RATING OF THE CONSTRUCTION PENETRATED.

WHERE ALLOWED BY APPLICABLE CODES, RULES, REGULATIONS AND MANUFACTURER

RECOMMENDATIONS, THE CONTRACTOR SHALL HAVE THE OPTION OF UTILIZING

THROUGH-PENETRATION FIRE STOP PRODUCTS IN LIEU OF THE SLEEVES AND FIRE STOPPING

MATERIALS SPECIFIED HEREIN FOR ALL PIPING AND FITTING PENETRATIONS OF FIRE-RATED

ASSEMBLIES. THROUGH-PENETRATION FIRE STOP PRODUCTS SHALL COMPLY WITH ASTM E-814

STANDARDS AND SHALL BE THE PRODUCTS OF PROSET SYSTEMS OR APPROVED EQUAL. THE

CONTRACTOR SHALL BE RESPONSIBLE FOR THE PROPER SELECTION, PLACEMENT AND

INSTALLATION OF THESE PRODUCTS. EACH THROUGH-PENETRATION FIRE STOP PRODUCT

SHALL BE COMPATIBLE WITH THE PIPE SIZE, PIPE MATERIAL, AND FIXTURE SERVED.

DEMOLITION PLAN GENERAL NOTES

1. VISIT SITE AND VERIFY EXISTING CONDITIONS PRIOR TO BID SUBMISSION.

DISCREPANCIES BETWEEN CONSTRUCTION INDICATED ON DRAWINGS AND

ACTUAL SITE CONDITIONS SHALL BE BROUGHT TO ARCHITECT’S ATTENTION

IMMEDIATELY IN WRITING.

2. DEMOLISHED ITEMS NOT INDICATED TO BE “DELIVERED TO OWNER” OR “TO BE

RELOCATED” SHALL BE REMOVED FROM SITE AS SOON AS POSSIBLE UNLESS

THEY ARE TO BE USED FOR REQUIRED PATCHING AND INFILLING OF EXISTING

CONSTRUCTION THAT IS TO REMAIN. NO OTHER DEMOLISHED ITEMS SHALL BE

STORED ON SITE.

3. DEMOLISHED ITEMS NOTED AS “DELIVER TO OWNER” OR “TO BE RELOCATED”

SHALL BE REMOVED OR DISASSEMBLED IN SUCH A MANNER THAT WILL NOT

DAMAGE THE ITEM AND PREVENT IT FROM BEING RELOCATED. REPAIR OR

REPLACE SUCH ITEMS, IF DAMAGED. NOTIFY OWNER’S REPRESENTATIVE

IMMEDIATELY IF DAMAGE HAS OCCURRED, AND SUBMIT A REPAIR SOLUTION TO

ARCHITECT FOR REVIEW.

4. TEMPORARILY STORE ITEMS INDICATED AS “DELIVER TO THE OWNER” IN ONSITE

LOCATION, DESIGNATED BY THE OWNER. OWNER SHALL MOVE ITEM(S), AS

NECESSARY, TO NOT HINDER OR DELAY PERFORMANCE OF WORK IN AREA.

5. TEMPORARILY STORE ITEMS INDICATED AS “TO BE RELOCATED” IN LOCATION

ONSITE AND PROTECT ITEMS FROM DAMAGE PRIOR TO INSTALLATION IN NEW

LOCATION.

6. ITEMS INDICATED “TO REMAIN” THAT ARE DAMAGED DURING THE PERFORMANCE

OF THE DEMOLITION WORK. SUCH DAMAGE SHALL BE REPORTED TO OWNER’S

REPRESENTATIVE IMMEDIATELY, AND SUBMIT A REPAIR SOLUTION TO ARCHITECT

FOR REVIEW.

7. COORDINATE DEMOLITION WORK WITH NEW CONSTRUCTION WORK IN EACH

AREA OF DEMOLITION. EXISTING CONSTRUCTION IN AREAS ADJACENT TO

DEMOLITION WORK SHALL BE PATCHED AND REPAIRED TO MATCH ORIGINAL

EXISTING CONDITION AS REQUIRED TO PROVIDE FOR NEW CONSTRUCTION

WORK IN AREA OF DEMOLITION.

8. ITEMS INDICATED TO BE REMOVED BY OWNER SHALL BE COMPLETED PRIOR TO

COMMENCEMENT OF WORK.

9. AT LOCATIONS WHERE A PORTION OF EXISTING CONSTRUCTION IS TO BE

REMOVED AND PREPARED FOR NEW INFILL CONSTRUCTION, OR AN OPENING IN A

WALL, ROOF, OR FLOOR IS CREATED BY DEMOLITION WORK, CONSTRUCT INFILL
