THE OUTLINE OF 'MEANS-AND-METHODS' NOTES BELOW FOR VERTICAL

COLD WATER RISER REPLACEMENTS INDICATED WITHIN THESE

DRAWINGS IS NOT INTENDED TO BE ALL-INCLUSIVE OF EFFORT

REQUIRED BY CONTRACTOR. NOR ARE THESE NOTES AND/OR

SUGGESTIONS MEANT TO LIMIT CONTRACTORS FROM DEVELOPING

THEIR OWN APPROACH THAT MAY BE CONSIDERED MORE COST

EFFECTIVE OR SAFE. THESE NOTES ARE MAINLY MEANT TO QUALIFY

EXISTING CONDITIONS AND DEFINE MINIMUM LEVEL OF PLANNING

REQUIRED BY VA FOR EACH OF THESE TIME SENSITIVE OUTAGES.

NO MAJOR WATER OUTAGE SHALL LAST MORE THAN 12 HOURS IN

DURATION. PLUMBING CONTRACTOR TO DETERMINE ADEQUATE

NUMBER OF PLUMBER CREWS REQUIRED TO PERFORM MULTIPLE

TASKS SIMULTANEOUSLY DURING OUTAGES. ALL OUTAGES SHALL BE

ASSUMED TO BE PERFORMED DURING WEEKEND OR NIGHT OVERTIME

HOURS WHEN BIDDING THIS PROJECT.

VERTICAL RISER REPLACEMENT (TYPE 1 - WITHIN MECHANICAL ROOM)

• FOR RISERS WITHIN MECHANICAL ROOMS, CONTRACTOR SHALL

CORE DRILL HOLES THROUGH FLOOR ADJACENT TO EXISTING

PLUMBING RISER FOR NEW INSTALLATION. EXISTING FLOOR

PENETRATIONS AND/OR SLEEVE SHALL BE PATCHED FLUSH TO

EXISTING FLOOR AS REQUIRE UPON DEMOLITION OF THOSE RISERS.

• EXISTINGT TAKE-OFF VALVES MAY REQUIRE RELOCATION FOR

CONNECTION INTO NEW RISER. VERIFY ADEQUATE ACCESS TO ALL

TAKE-OFF VALVES AND PROVIDE WITH NEW LAMINATE SIGNAGE.

ANY VALVES FOUND AT INACCESSIBLE LOCATIONS SHALL BE

RELOCATED BY CONTRACTOR.

• REFER TO CLIN 3001 FOR REPLACEMENT OF ALL ICRCUIT SETTER

VALVES WITHIN ENTIRE BUILDING. PLUMBING CONTRACTOR MAY

OPT TO HAVE DEDICATED CREWS ASSIGNED TO THIS TASK DURING

RISER OUTAGE TO LIMIT NUMBER OF SECONDARY OUTAGES

REQUIRED. HOWEVER, IF ENOUGH PLUMBERS ARE AVAILABLE TO

ACHIEVE THIS DURING LIMITED OUTAGE TIMEFRAME, THAN REFER

TO GENERAL NOTES ON DRAWING PP002 FOR 'LARGE OUTAGES' TO

PERFORM PRIOR TO THE MAJOR RISER OUTAGE.

VERTICAL RISER REPLACEMENT (TYPE 2 - WITHIN ENCLOSED SHAFT)

• IN GENERAL, MAJOR RATED SHAFTS SHOWN IN THESE DRAWINGS

HAVE EXISTING FULL SIZED ACCESS DOOR FROM BASE OF SHAFT

ON FIRST FLOOR LEVEL. HOWEVER, THAT IS TYPICALLY THE ONLY

ACCESS INTO THESE SHAFTS THAT ARE FULLY OPEN (NO

INTERMEDIATE FLOOR STRUCTURES) UP THROUGH PENTHOUSE

LEVEL WHERE RATED WALLS ARE BUILT-UP WITH LID (TYPICALLY

12'+) WITHIN ENCLOSED PENTHOUSE LEVEL.

• IN ORDER TO GAIN ACCESS TO TOP OF SHAFT, CONTRACTOR WILL

BE REQUIRED TO FURNSIH AND INSTALL FIRE RATED DOOR

ASSEMBLIES FROM PENTHOUSE LEVEL. THESE DOORS MAY BE

USED IN CONJUCTION OF RIGGING FOR BOSUN CHAIRS FROM TOP

OF SHAFT IF CONTRACTOR DEEMS THAT AS SAFE AFTER REVIEW

WITH THEIR INTERNAL SAFETY OFFICIAL.

• IN ADDITION TO ACCESS ON TOP LEVEL OF SHAFT, CONTRACTOR

WILL HAVE OPPORTUNITIES TO INSTALL 24"X24" OR 48"X24" FIRE

RATED ACCESS PANELS ON ANY OTHER LEVEL REQUIRED (BUT

ONLY FROM INTERSTITIAL SPACE, INSTALLATION OF ACCESS

PANELS FROM PATIENT CARE AREAS WILL NOT BE PERMITTED).

• CONTRACTOR WILL BE REQUIRED TO PROVIDE THEIR OWN

SCAFFOLDING REQUIRED AT EACH LEVEL TO INSTALL NEW COLD

WATER RISERS ADJACENT TO EXISTING PRIOR TO SIOWTCHOVER

OUTAGE. SCAFFOLDS SHOULD BE STRATEGICALLY PLACE TO

ALLOW ACCESS FOR RECONNECTION TO FLOOR TAKE-OFF PIPING

INSIDE OF EACH SHAFT.

• EXISTING CONDITION PDF SKETCHES ARE PROVIDED ON DRAWINGS

WHERE WORK INSIDE CONFINED AREAS OF RATED SHAFTS IS

REQUIRED. THESE SKETCHES ARE FOR CONTRACTOR REFERENCE

ONLY AND MAY NOT FULLY INDICATE ALL SERVICES WITHIN SHAFT

ENCLOSURES. CONTRACTOR WILL BE REQUIRED TO FIELD VERIFY

ACTUAL SITE CONDITIONS OF EACH SHAFT WHILE DEVELOPING

ACCESS AND SAFETY PLANNING.

NOTE THAT SOME AREAS HAVE EXISTING COPPER MAINS INTENDED TO

REPLACE GALVANIZED RISERS. HOWEVER THESE MAINS WERE

INSTALLED UP TO 15-25 YEARS AGO AND THEIR INTEGRITY IS

QUESTIONABLE. CONTRACTOR MAY UTILIZE THE EXISTING ROUTE, AND

CORRESPONDING SUPPORT HANGERS, BUT MUST FULLY REMOVE ALL

ABANDONED/UNUSED COPPER PIPING MAINS. ONCE OFF SITE THE

CONTRACTOR MAY TAKE OWNERSHIP OF PIPING FOR RECYLCING OR

REPURPOSING, BUT IT SHALL NOT BE UTILIZED WITHIN THIS PROJECT.

NO EXISTING PIPING WILL BE ALLOWED TO BE LEFT ABANDONED. SOME

AREAS HAVE RESTRICITVE ACCESS DUE TO SURROUNDING PIPES

AND/OR STRUCTURE AND MAY REQUIRE TEMPORARY REMOVAL OF

PIPING OR DUCTWORK TO GAIN ACCESS FOR DEMOLITION.

CONTRACTOR TO ASSUME SOME LEVEL OF DISCONNECT/RECONNECT

OF EXISTING SERVICES TO GAIN ACCCESS FOR COMPLETE DEMOLITION

OF EXISTING PIPING, OR INSTALLATION OF NEW PIPE IN CONGESTED

AREAS. REFER TO DRAWING NOTES FOR ADDITIONAL INFORMATION.

THE OUTLINE OF 'MEANS-AND-METHODS' NOTES BELOW FOR VERTICAL

COLD WATER RISER REPLACEMENTS INDICATED WITHIN THESE

DRAWINGS IS NOT INTENDED TO BE ALL-INCLUSIVE OF EFFORT

REQUIRED BY CONTRACTOR. NOR ARE THESE NOTES AND/OR

SUGGESTIONS MEANT TO LIMIT CONTRACTORS FROM DEVELOPING

THEIR OWN APPROACH THAT MAY BE CONSIDERED MORE COST

EFFECTIVE OR SAFE. THESE NOTES ARE MAINLY MEANT TO QUALIFY

EXISTING CONDITIONS AND DEFINE MINIMUM LEVEL OF PLANNING

REQUIRED BY VA FOR EACH OF THESE TIME SENSITIVE OUTAGES.

NO MAJOR WATER OUTAGE SHALL LAST MORE THAN 12 HOURS IN

DURATION. PLUMBING CONTRACTOR TO DETERMINE ADEQUATE

NUMBER OF PLUMBER CREWS REQUIRED TO PERFORM MULTIPLE

TASKS SIMULTANEOUSLY DURING OUTAGES. ALL OUTAGES SHALL BE

ASSUMED TO BE PERFORMED DURING WEEKEND OR NIGHT OVERTIME

HOURS WHEN BIDDING THIS PROJECT.

VERTICAL RISER REPLACEMENT (TYPE 1 - WITHIN MECHANICAL ROOM)

• FOR RISERS WITHIN MECHANICAL ROOMS, CONTRACTOR SHALL

CORE DRILL HOLES THROUGH FLOOR ADJACENT TO EXISTING

PLUMBING RISER FOR NEW INSTALLATION. EXISTING FLOOR

PENETRATIONS AND/OR SLEEVE SHALL BE PATCHED FLUSH TO

EXISTING FLOOR AS REQUIRE UPON DEMOLITION OF THOSE RISERS.

• EXISTINGT TAKE-OFF VALVES MAY REQUIRE RELOCATION FOR

CONNECTION INTO NEW RISER. VERIFY ADEQUATE ACCESS TO ALL

TAKE-OFF VALVES AND PROVIDE WITH NEW LAMINATE SIGNAGE.

ANY VALVES FOUND AT INACCESSIBLE LOCATIONS SHALL BE

RELOCATED BY CONTRACTOR.

• REFER TO CLIN 3001 FOR REPLACEMENT OF ALL ICRCUIT SETTER

VALVES WITHIN ENTIRE BUILDING. PLUMBING CONTRACTOR MAY

OPT TO HAVE DEDICATED CREWS ASSIGNED TO THIS TASK DURING

RISER OUTAGE TO LIMIT NUMBER OF SECONDARY OUTAGES

REQUIRED. HOWEVER, IF ENOUGH PLUMBERS ARE AVAILABLE TO

ACHIEVE THIS DURING LIMITED OUTAGE TIMEFRAME, THAN REFER

TO GENERAL NOTES ON DRAWING PP002 FOR 'LARGE OUTAGES' TO

PERFORM PRIOR TO THE MAJOR RISER OUTAGE.

VERTICAL RISER REPLACEMENT (TYPE 2 - WITHIN ENCLOSED SHAFT)

• IN GENERAL, MAJOR RATED SHAFTS SHOWN IN THESE DRAWINGS

HAVE EXISTING FULL SIZED ACCESS DOOR FROM BASE OF SHAFT

ON FIRST FLOOR LEVEL. HOWEVER, THAT IS TYPICALLY THE ONLY

ACCESS INTO THESE SHAFTS THAT ARE FULLY OPEN (NO

INTERMEDIATE FLOOR STRUCTURES) UP THROUGH PENTHOUSE

LEVEL WHERE RATED WALLS ARE BUILT-UP WITH LID (TYPICALLY

12'+) WITHIN ENCLOSED PENTHOUSE LEVEL.

• IN ORDER TO GAIN ACCESS TO TOP OF SHAFT, CONTRACTOR WILL

BE REQUIRED TO FURNSIH AND INSTALL FIRE RATED DOOR

ASSEMBLIES FROM PENTHOUSE LEVEL. THESE DOORS MAY BE

USED IN CONJUCTION OF RIGGING FOR BOSUN CHAIRS FROM TOP

OF SHAFT IF CONTRACTOR DEEMS THAT AS SAFE AFTER REVIEW

WITH THEIR INTERNAL SAFETY OFFICIAL.

• IN ADDITION TO ACCESS ON TOP LEVEL OF SHAFT, CONTRACTOR

WILL HAVE OPPORTUNITIES TO INSTALL 24"X24" OR 48"X24" FIRE

RATED ACCESS PANELS ON ANY OTHER LEVEL REQUIRED (BUT

ONLY FROM INTERSTITIAL SPACE, INSTALLATION OF ACCESS

PANELS FROM PATIENT CARE AREAS WILL NOT BE PERMITTED).

• CONTRACTOR WILL BE REQUIRED TO PROVIDE THEIR OWN

SCAFFOLDING REQUIRED AT EACH LEVEL TO INSTALL NEW COLD

WATER RISERS ADJACENT TO EXISTING PRIOR TO SIOWTCHOVER

OUTAGE. SCAFFOLDS SHOULD BE STRATEGICALLY PLACE TO

ALLOW ACCESS FOR RECONNECTION TO FLOOR TAKE-OFF PIPING

INSIDE OF EACH SHAFT.

• EXISTING CONDITION PDF SKETCHES ARE PROVIDED ON DRAWINGS

WHERE WORK INSIDE CONFINED AREAS OF RATED SHAFTS IS

REQUIRED. THESE SKETCHES ARE FOR CONTRACTOR REFERENCE

ONLY AND MAY NOT FULLY INDICATE ALL SERVICES WITHIN SHAFT

ENCLOSURES. CONTRACTOR WILL BE REQUIRED TO FIELD VERIFY

ACTUAL SITE CONDITIONS OF EACH SHAFT WHILE DEVELOPING

ACCESS AND SAFETY PLANNING.

NOTE THAT SOME AREAS HAVE EXISTING COPPER MAINS INTENDED TO

REPLACE GALVANIZED RISERS. HOWEVER THESE MAINS WERE

INSTALLED UP TO 15-25 YEARS AGO AND THEIR INTEGRITY IS

QUESTIONABLE. CONTRACTOR MAY UTILIZE THE EXISTING ROUTE, AND

CORRESPONDING SUPPORT HANGERS, BUT MUST FULLY REMOVE ALL

ABANDONED/UNUSED COPPER PIPING MAINS. ONCE OFF SITE THE

CONTRACTOR MAY TAKE OWNERSHIP OF PIPING FOR RECYLCING OR

REPURPOSING, BUT IT SHALL NOT BE UTILIZED WITHIN THIS PROJECT.

NO EXISTING PIPING WILL BE ALLOWED TO BE LEFT ABANDONED. SOME

AREAS HAVE RESTRICITVE ACCESS DUE TO SURROUNDING PIPES

AND/OR STRUCTURE AND MAY REQUIRE TEMPORARY REMOVAL OF

PIPING OR DUCTWORK TO GAIN ACCESS FOR DEMOLITION.

CONTRACTOR TO ASSUME SOME LEVEL OF DISCONNECT/RECONNECT

OF EXISTING SERVICES TO GAIN ACCCESS FOR COMPLETE DEMOLITION

OF EXISTING PIPING, OR INSTALLATION OF NEW PIPE IN CONGESTED

AREAS. REFER TO DRAWING NOTES FOR ADDITIONAL INFORMATION.
