About this file

Written by GovTribe AI · Aug 8, 2024

This document contains drawings and information related to the rehabilitation of the Garfield Water Tank located in Crater Lake National Park, Klamath County, Oregon. The drawings provide details on the existing tank configuration, proposed lining and repair plan, and typical liner installation details. Key details include:

The existing steel tank is divided into two cells and requires removal and replacement of the existing membrane liner in both cells. Minor concrete and piping repairs may also be necessary. The contractor will need to isolate one cell at a time to perform the work, with one cell remaining operational at all times. The project also includes disinfection of the tank upon completion of the liner installation. Referenced drawings indicate the tank has undergone several prior modifications in 1997, 2003, and 2009.

This information is part of a federal contract opportunity solicitation, number 140P8424R0015, issued by the Department of the Interior National Park Service Pacific West Region for the Garfield Water Tank Rehabilitation project at Crater Lake National Park. The solicitation provides details on how to access the full solicitation package and submit questions.

WHERE PUBLIC UTILITY FIXTURES OR FACILITIES ARE SHOWN AS EXISTING ON

THE PLANS OR ENCOUNTERED WITHIN THE CONSTRUCTION AREA, IT SHALL BE

THE RESPONSIBILITY OF THE CONTRACTOR TO NOTIFY THE OWNERS OF THESE

UTILITIES PRIOR TO THE BEGINNING OF ANY CONSTRUCTION INVOLVING

EXCAVATION. THE CONTRACTOR SHALL AFFORD ACCESS TO THESE FACILITIES

FOR NECESSARY MODIFICATION OF SERVICES OR RELOCATION. UNDERGROUND

FACILITIES, STRUCTURES AND UTILITIES HAVE BEEN PLOTTED FROM AVAILABLE

SURVEYS, RECORDS AND UTILITY OPERATOR LOCATION MARKINGS; THEREFORE

THEIR LOCATIONS MUST BE CONSIDERED APPROXIMATE ONLY. TYPE, SIZE AND

GENERAL LOCATION OF THE FACILITIES WERE REQUESTED OF THE OPERATORS

AND SHOWN ON THE PLANS, AND IF NECESSARY, UPDATED WITHIN 90 DAYS OF

COMPLETION OF THE FINAL PLANS. IT IS POSSIBLE THERE MAY BE OTHERS, THE

EXISTENCE OF WHICH IS PRESENTLY NOT KNOWN OR SHOWN. IT IS THE

CONTRACTOR'S RESPONSIBILITY TO DETERMINE THEIR EXISTENCE AND EXACT

LOCATION AND TO AVOID DAMAGE THERETO. NO CLAIMS FOR ADDITIONAL

COMPENSATION WILL BE ALLOWED TO THE CONTRACTOR FOR ANY

NOTES

1. THE INTENT OF THIS SHEET IS TO SHOW THE GENERAL TANK

LAYOUT AND CONFIGURATION FOR OPERATION. THE ACTUAL

TANK PIPING IS MORE COMPLEX DUE TO SEVERAL PRIOR

MODIFICATIONS. THE PIPING IN THIS DIAGRAM SHOULD ONLY

BE CONSIDERED APPROXIMATE

2. SEE FOLLOWING SHEETS THAT REFERENCE HOW THE TANK

WAS PREVIOUSLY MODIFIED.

3. THE INTENT IN PROVIDING THE REFERENCE PLANS IS TO

NOTES

1. THE EXISTING MEMBRANE LINER IN BOTH CELLS SHALL BE REMOVED AND REPLACED.

2. THE EAST CELL SHALL BE WORKED ON FIRST.

3. ISOLATE THE EAST CELL BY CLOSING THE INLET VALVE. ALLOW THE TANK TO DRAIN BY

CONSUMPTIVE USE. NPS STAFF WILL ASSIST WITH ALL VALVE OPERATION.

4. ONE CELL MUST REMAIN FULLY OPERATIONAL AT ALL TIMES.

5. ONCE DRAINED, REMOVE THE EXISTING LINER AND BATTENS AND CLEAN TANK INTERIOR.

6. FULLY INSPECT TANK AND MAKE MINOR REPAIRS WHERE REQUIRED. SEE CONCRETE AND

PIPING REPAIR NOTES BELOW.

7. NPS STAFF SHALL INSPECT THE SURFACE AND REPAIRS PRIOR TO INSTALLING THE NEW

LINER.

8. INSTALL NEW LINER. ALL WETTED SURFACES SHALL BE FULLY LINED. LINER SHALL EXTEND

TO WITHIN 6" OF TOP OF TANK..

9. LINER SEAMS SHALL BE PLACED VERTICALLY.

10. CONTRACTOR SHALL IDENTIFY AND ADJUST FOR ALL PENETRATIONS. INFORMATION IS

PROVIDED IN THIS PLAN SET THAT IDENTIFIES WHAT IS KNOWN ABOUT THIS TANK.

HOWEVER THE ACTUAL NUMBER AND LOCATION OF PENETRATIONS MAY VARY.

11. LINER DETAILS ON SHEET C4 ARE TYPICAL AND MAY BE SUPERCEDED BY MANUFACTURER.

12. TYPICAL LINER ATTACHMENTS AND PENETRATION DETAILS ARE SHOWN ON SHEET C4.

ADDITIONAL DETAILS MAY BE REQUIRED AND SHALL BE ACCORDING TO THE LINER

MANUFACTURER. ALL METAL COMPONENTS SHALL BE STAINLESS STEEL.

13. UPON COMPLETION OF THE EAST CELL, FILL AND DISINFECT ACCORDING TO THE

SPECIFICATIONS. PERFORM A CROSS-OVER AND REPEAT THE PROCESS FOR THE WEST

CELL.

CONCRETE & PIPING REPAIR

1. THE EXTENT TO WHICH CONCRETE AND PIPING REPAIRS IS REQUIRED IS UNKNOWN. FOR

THE PURPOSES OF THIS PROJECT IT IS NOT THE INTENT TO PERFORM MAJOR STRUCTURAL

REPAIRS TO THE TANK. RATHER, THE INTENT IS TO MAKE MINOR SUPERFICIAL REPAIRS

WHILE THE LINER IS OUT IN ORDER TO PRESERVE THE LIFE OF THE TANK. MINOR REPAIRS

INCLUDE PATCHING SPALLS, SEALING CRACKS, AND SEALING PENETRATIONS.

2. FOR THE PURPOSE OF THIS CONTRACT, THE CONTRACTOR SHOULD ASSUME THAT

APPROXIMATELY 100 SF OF SURFACE SPALLS WILL NEED TO BE PATCHED, ONE PIPE

PENETRATION WILL NEED TO BE REPAIRED, AND APPROXIMATELY 500 LF OF CRACKS WILL

NEED TO BE SEALED. AT THIS TIME IT IS ASSUMED THAT NO PIPING/VAVLE REPAIRS WILL BE

REQUIRED, OTHER THAN THOSE REQUIRED TO JOIN EXISTING PIPES TO THE NEW LINER.

3. ONE OF THE MAIN OBJECTIVES OF THIS PROJECT WILL BE TO IDENTIFY THE CAUSE OF THE

OBSERVED LEAK IN THE EAST CELL, AND REPAIR IT IF THE REPAIR EFFORT IS WITHIN

SCOPE.

4. IF MORE SUBSTANTIAL REPAIRS ARE REQUIRED, THEY WILL ADDRESSED SEPARATELY OR

THROUGH A CONTRACT MODIFICATION.

5. THE SPECIFICATIONS INCLUDE A SECTION FOR CONCRETE REPAIR. THE INTENT OF THE

SPECIFICATION IS TO COVER BASIC CONCRETE REPAIR REQUIREMENTS. THIS SECTION IS

NOT INTENDED TO BE ALL INCLUSIVE. IF ADDITIONAL REPAIRS ARE REQUIRED THE NPS

WILL WORK WITH THE CONTRACTOR TO IDENTIFY AND IMPLEMENT THE MOST

APPROPRIATE REPAIR METHODS.
