1. IN GENERAL, EXISTING STRUCTURES, EQUIPMENT, AND FACILITIES ARE SHOWN

AS LIGHT LINE WEIGHTS OR SCREENED BACKGROUND. NEW STRUCTURES,

EQUIPMENT, AND FACILITIES ARE SHOWN IN HEAVY LINE WEIGHTS. OTHER

DISCIPLINES MAY SCREEN NEW STRUCTURES TO SHOW THEIR INFORMATION.

2. ALL EXISTING TREES TO REMAIN UNLESS OTHERWISE SPECIFIED.

3. ALL DISTURBED ASPHALT, GRASS, DRAINAGE PATTERNS, ROADSIDE DITCHES,

TRAILS AND GRADE SHALL BE RESTORED TO ITS ORIGINAL CONDITION OR AS

CALLED FOR ON THE CONTRACT DOCUMENTS, WHICHEVER IS MORE STRINGENT.

4. SCHEDULE ALL EXISTING UTILITY LINE SHUTDOWNS WITH THE CONTRACTING

OFFICER.

5. ALL CONNECTIONS TO EXISTING MAINS SHALL BE MADE BY THE CONTRACTOR

ONLY AFTER THE PROPOSED CONNECTION PROCEDURE AND WORK SCHEDULE

CONTRACTOR SHALL RESUBMIT THE REQUEST, MAKING MODIFICATIONS IN A

MANNER ACCEPTABLE TO THE CONTRACTING OFFICER. ALL CONNECTIONS SHALL

ONLY BE MADE ON AGREED UPON DATE AND TIME. IF THE CONTRACTOR DOES

NOT INITIATE AND COMPLETE THE CONNECTION WORK IN THE AGREED UPON

MANNER, THE CONTRACTOR SHALL BE REQUIRED TO RESCHEDULE THE

EXTENT SUCH INFORMATION HAS BEEN MADE AVAILABLE OR DISCOVERED BY

THE ENGINEER. IT IS EXPECTED THAT THERE MAY BE DISCREPANCIES AND

OMISSIONS IN THE LOCATION AND QUANTITIES OF EXISTING UTILITIES AND

STRUCTURES SHOWN. THIS INFORMATION IS SHOWN FOR THE CONVENIENCE OF

THE CONTRACTOR BUT IS NOT GUARANTEED TO BE EITHER CORRECT OR

COMPLETE AND ALL RESPONSIBILITY FOR THE ACCURACY AND COMPLETENESS

THEREOF IS EXPRESSLY DISCLAIMED. THE CONTRACTOR SHALL MAKE SUCH

INVESTIGATION AS NECESSARY TO VERIFY ITS CORRECTNESS AND

COMPLETENESS.

SERVICE CONNECTIONS, AND ALL OTHER SURFACE AND SUB-SURFACE

FEATURES PRIOR TO CONSTRUCTION. ANY FEATURES DAMAGED BY

CONTRACTOR'S ACTIVITIES SHALL BE REPLACED TO PRE-CONSTRUCTION

CONDITION AT NO ADDITIONAL EXPENSE TO THE GOVERNMENT. ANY FIELD

LOCATED EXISTING CONDITIONS IMPACTING NEW WORK SHALL BE IMMEDIATELY

BROUGHT TO THE CONTRACTING OFFICER'S ATTENTION.

10. ALL EXISTING VALVES AND EQUIPMENT SHALL ONLY BE OPERATED BY THE THE

NATIONAL PARK SERVICE.

1. CONTRACTOR SHALL PROVIDE A FRAC-OUT CONTINGENCY PLAN, INCLUDING MINIMUM

REQUIREMENTS PER PROJECT SPECIFICATIONS, PRIOR TO CONSTRUCTION.

2. CONTRACTOR SHALL PROVIDE MONITORING FULL TIME DURING HORIZONTAL DIRECTION

DRILLING (HDD) OPERATIONS.

1. THE BASE BID FOR THIS PROJECT INCLUDES REPLACING THE WATER MAIN FROM

CAMPGROUND TO STA. 13+13, AND MODIFYING THE EXISTING WATER PLANT.

2. BID OPTION 1 INCLUDES REPLACING THE REMAINING WATER DISTRIBUTION SYSTEM

FROM STA. 13+13 THROUGH THE REST OF THE WOLF CREEK AREA, INCLUDING NEW

SERVICE CONNECTIONS.

3. THE EXISTING SYSTEM FEEDS THE DISTRIBUTION SYSTEM BY SENDING FLOW THROUGH

THE BOOSTER STATION. FLOW THEN FLOWS BACKWARDS TO SUPPLY THE SYSTEM.

4. THE BID OPTION WOULD ELIMINATE THE REVERSE FLOW SCENARIO AND FEED THE

NOTES

1. WORK TO THE PLANT WILL ONLY BE ALLOWED AFTER THE WATER MAIN CONSTRUCTION.

2. PRIOR TO WORKING ON THE PLANT, THE CONTRACTOR SHALL VERIFY STATIC

PRESSURE , AND CONDUCT A FLOW TEST. THE PURPOSE OF THE FLOW TEST WILL BE

TO VERIFY THAT THE MODIFIED WATER MAIN CAN DELIVER THE AMOUNT OF FLOW

REQUIRED BASED ON A 4-INCH LINE SIZE. THE FLOW TEST WILL CONFIRM THAT THERE

ARE NO OTHER RESTRICTIONS ALONG THE LINE THAT THE NPS IS NOT AWARE OF.

3. IF THE FLOW TEST FAILS, NOTIFY THE NPS IMMEDIATELY.

4. THERE IS AN EXISTING HYDRANT ASSEMBLY NEAR THE TREATMENT BUILDING THAT

WAS DAMAGED AND IS BADLY CORRODED. REPLACE THE FULL ASSEMBLY INCLUDING

THE TEE FITTING. FULLY EXCAVATE AND REMOVE SOIL WITHIN 3' OF ALL ASSEMBLY

COMPONENTS. BACKFILL WITH COMPACTED APPROVED SOIL BROUGHT IN FROM

OUTSIDE SOURCE. THE SOIL THAT WAS USED TO BACKFILL THE EXISTING ASSEMBLY

WAS FOUND TO BE BEACH SAND WHICH LED TO THE FAILURE OF THE FITTINGS DUE TO

NOTES

1. WATER MAIN CONSTRUCTED UNDER THE BID OPTION MAY BE CONSTRUCTED USING A

VARIETY OF TECHNIQUES, INCLUDING TRENCHED AND TRENCHLESS.

2. TRENCHLESS TECHNIQUES MAY INCLUDE HDD, OR PIPE BURSTING.

3. IT MAY BE FEASIBLE TO UTILIZE THE EXISTING 6" WATER MAIN BY SLIP LINING WITH 4"

HDPE PIPE. SLIGHT ADJUSTMENTS TO THE PLAN WILL BE REQUIRED FROM WHAT IS

SHOWN.

NOTES

1. WORK TO THE PLANT WILL ONLY BE ALLOWED AFTER THE WATER MAIN CONSTRUCTION.

2. PRIOR TO WORKING ON THE PLANT, THE CONTRACTOR SHALL VERIFY STATIC

PRESSURE , AND CONDUCT A FLOW TEST. THE PURPOSE OF THE FLOW TEST WILL BE

TO VERIFY THAT THE MODIFIED WATER MAIN CAN DELIVER THE AMOUNT OF FLOW

REQUIRED BASED ON A 4-INCH LINE SIZE. THE FLOW TEST WILL CONFIRM THAT THERE

ARE NO OTHER RESTRICTIONS ALONG THE LINE THAT THE NPS IS NOT AWARE OF.

3. IF THE FLOW TEST FAILS, NOTIFY THE NPS IMMEDIATELY.

4. THERE IS AN EXISTING HYDRANT ASSEMBLY NEAR THE TREATMENT BUILDING THAT

WAS DAMAGED AND IS BADLY CORRODED. REPLACE THE FULL ASSEMBLY INCLUDING

THE TEE FITTING. FULLY EXCAVATE AND REMOVE SOIL WITHIN 3' OF ALL ASSEMBLY

COMPONENTS. BACKFILL WITH COMPACTED APPROVED SOIL BROUGHT IN FROM

OUTSIDE SOURCE. THE SOIL THAT WAS USED TO BACKFILL THE EXISTING ASSEMBLY

WAS FOUND TO BE BEACH SAND WHICH LED TO THE FAILURE OF THE FITTINGS DUE TO

CORROSION. IF BID OPTION 1 IS EXECUTED, THE FIRE ASSEMBLY WILL CONNECT

DIRECTLY TO THE NEW 4" MAIN.
