TYPICAL VALVE 4-V-X03 REPLACEMENT

SCALE: NTS

NOTES TO CONTRACTOR:

1. CONTRACTOR SHALL SUBMIT TO LBU A WRITTEN REQUEST TO DEWATER THE PIPELINE TWO (2)

WEEKS IN ADVANCE OF THE VALVE REPLACEMENT. LBU WILL BE RESPONSIBLE FOR CLOSING

ALL THE DESIGNATED SHUT-DOWN VALVES AND DEWATERING THE PIPELINE. THE

CONTRACTOR SHALL EXPECT TO PUMP OUT ANY REMAINING NUISANCE WATER IN THE PIPE

AND DISCHARGE THE WATER TO A LOCATION DESIGNATED BY LBU. THE CONTRACTOR SHALL

DECHLORINATE THE NUISANCE WATER TO NEUTRALIZE THE CHLORINE TREATED WATER PRIOR

TO DISCHARGE.

2. CONTRACTOR SHALL PROTECT IN PLACE EXISTING PIPING, APPURTENANCES, ELECTRICAL

EQUIPMENT, AND ALL OTHER PIPING AND EQUIPMENT NOT TO BE REPLACED DURING

CONSTRUCTION OPERATIONS UNLESS OTHERWISE NOTED. ANY PIPING AND EQUIPMENT

DAMAGED BY THE CONTRACTOR SHALL BE REPLACED TO THE CONDITION EQUAL TO OR

BETTER THAN THE EXISTING CONDITION.

3. CONTRACTOR SHALL DISINFECT PIPING PER GENERAL NOTE NO. 20.

4. CONTRACTOR SHALL FIELD VERIFY FLANGE BOLT PATTERNS MATCH PRIOR TO CONNECTING.

5. ALL FITTINGS CALLED OUT ON PLANS SHALL BE RELINED PER SPECIFICATION SECTION 33 11 18.

REMOVE EXISTING LINING PRIOR TO INSTALLATION OF NEW.

6. ALL FLANGES SHALL BE JOINED WITH 316 SS NUTS, BOLTS, AND WASHERS.

7. PROTECT IN PLACE EXISTING 42" STEEL SPOOL AND REHABILITATE MORTAR LINING AS

FOLLOWS:

ALTERNATIVE 1: IF THE EXISTING LINING IS IN FAIR TO GOOD CONDITION, REMOVE THE RUST

FROM THE EXPOSED PIPE AND REPAIR THE MORTAR LINING INSIDE OF THE PIPE, ADD 3" OF

MORTAR REPAIR FROM THE INSIDE BASIN FACE AND FEATHER INTO THE EXISTING

CONCRETE WALL TO COVER THE PIPE EDGE.

ALTERNATIVE 2: IF THE EXISTING LINING IS IN POOR CONDITION, REMOVE THE CEMENT

MORTAR LINING AND APPLY AN EPOXY LINING TO THE EXPOSED STEEL PIPE (12 MILS

MINIMUM UP TO 16 MILS). APPLY A MINIMUM OF TWO COATS.
