AVOID INTERFERENCE FROM OTHER SIDE FASTENERS. REFER TO NOTE 3 FOR ADDITIONAL INFORMATION

5. ENSURE THAT DUNNAGE PLACEMENT DOES NOT INTERFERE WITH CATHODIC ANODES ON THE FACE OF THE GATE

6. ENSURE THAT ALL ELEMENTS OF THE GATE ARE SECURED AND THERE IS AMPLE ROOM AROUND THE GATE FOR PERSONNEL AND VEHICLE ACCESS

7. PROVIDE FLAGGING AROUND THE PERIMETER

8. WHEN THE GATE IS READY TO BE INSTALLED, HAVE A THROUGH PLAN TO INSPECT THE SKIN FACE OF THE GATE TO ENSURE NO DAMAGE HAS OCCURRED ON THE

COATING.

9. ONCE UPPER LEAF IS REPAIRED BUT BEFORE ROTATING IT TO THE VERTICAL POSITION, ENSURE PROPER DUNNAGE AND RUBBER MATS ARE PLACED AT THE

ROTATION POINTS, WHICH ARE AT THE BOTTOM PLATES OF EACH VERTICAL-BEAM-ASSY.

10. FINAL DUNNAGE AND RUBBER MATS SETUP AND MATERIAL GRADE MUST BE DESIGNED AND APPROVED BY A QUALIFIED SUPPLIER.

11. QUANTITY OF MAT LAYERS AND THICKNESS MUST BE DESIGNED AND APPROVED BY A QUALIFIED SUPPLIER.

UPPER GATE, UPSTREAM SIDE - CATHODIC PROTECTION ANODE LAYOUT

A

4'0 2' 8'

GENERAL INSTALLATION NOTES FOR ALL GALVANIC (MAGNESIUM) ANODES:

1. THERE ARE 11 GATES IN TOTAL, EACH WITH AN UPPER AND LOWER LEAF.

CATHODIC PROTECTION SHALL BE INSTALLED AS SHOWN (ON THESE

CATHODIC PROTECTION PLANS) ON EACH AND ALL OF THE SPILLWAY

GATES.

2. PRIOR TO PAINTING (COATING) THE GATES, PERFORM ALL REQUIRED

WELDING OF MOUNTING BOLTS, ROUTING CLAMPS, AND ANY OTHER

REQUIRED WELDING, TO BE ACCOMPLISHED AS SHOWN IN THE ANODE

MOUNTING DETAILS AND IN THE LOCATIONS AS SHOWN IN THE CATHODIC

PROTECTION PLAN AND LAYOUT DRAWINGS. WRAP THE MOUNTING BOLT

THREADS WITH TAPE TO PREVENT THE GATE COATING MATERIAL FROM

ADHERING TO THE THREADS. IT SHALL BE THE RESPONSIBILITY OF THE

CONTRACTOR'S CORROSION ENGINEER (AS SPECIFIED IN 26 42 14.00 10,

CATHODIC PROTECTION SYSTEMS (SACRIFICIAL ANODE)) TO COORDINATE

THE EXACT LOCATIONS OF THE ANODE MOUNTING BOLTS, ETC., WITH THE

ANODE SUPPLIER AND THE EXISTING GATE..

3. THE GATE SHALL BE PAINTED IN ACCORDANCE WITH SPECIFICATION 09 97

02.00 25, PAINTING: HYDRAULIC STRUCTURES.

4. ONCE THE GATES ARE PAINTED, AND IMMEDIATELY PRIOR TO INSTALLING

THE ANODES, REMOVE THE TAPE FROM THE BOLTS. REMOVE ANY PAINT

FROM THE THREAD SIDE OF THE MOUNTING BOLT HEAD. BEFORE

MOUNTING THE ANODES, REMOVE THE EPOXY COATING FROM THE AREA

ADJACENT TO THE ANODE MOUNTING HOLES. THESE PROCEDURES MUST

BE ACCOMPLISHED IN ORDER TO INSURE PROPER ELECTRICAL CONTACT

BETWEEN THE ANODE STRAP, BOLT, NUTS, AND WASHERS.

5. AFTER EACH ANODE IS INSTALLED, REMOVE THE PLASTISOL COATING FROM

THE HULL MAGNESIUM ANODE SURFACE AS DETAILED IN THESE CATHODIC

PROTECTION DRAWINGS FOR THE SPECIFIC ANODES BEING INSTALLED.

THEN CHECK THE CONTINUITY BETWEEN THE ANODE AND GATE

STRUCTURAL STEEL. DISCONTINUOUS ANODES ARE TO BE REMOVED,

POINTS OF CONNECTIONS CLEANED OF ANY EXCESS EPOXY OR PAINT, AND

THEN REINSTALLED AS REQUIRED TO ACHIEVE THE DESIRED CONTINUITY.

6. AFTER ANODE INSTALLATION, ALL EXPOSED STEEL SURFACES (INCLUDING

BOLTS, NUTS, WASHERS, STRAPS, AND ROUTING CLAMPS) SHALL BE

THOROUGHLY CLEANED AND PAINTED USING PAINTS AND COATINGS

PRESCRIBED FOR GATE (SEE SPECIFICATION 09 97 02.00 25, PAINTING:

HYDRAULIC STRUCTURES). CARE SHOULD BE TAKEN TO NOT PAINT ANY OF

THE MAGNESIUM ANODE MATERIAL.

7. MINOR ADJUSTMENT OF ANODE LOCATIONS SHALL BE ACCOMPLISHED, AS

COORDINATED WITH THE CONTRACTOR'S CORROSION ENGINEER, IN ORDER

TO AVOID CONFLICT WITH OTHER GATE STRUCTURAL OR MECHANICAL

COMPONENTS AND/OR OTHER OBSTACLES.

8. THE CONTRACTOR SHALL OBTAIN THE SERVICES OF A CORROSION

ENGINEER TO SUPERVISE, COORDINATE, TEST, AND PERFORM ALL OTHER

SERVICES AS REQUIRED BY THE SPECIFICATIONS IN ORDER TO INSURE

THAT ALL ASPECTS OF THE CATHODIC PROTECTION LAYOUT AND

INSTALLATION ARE IN FULL COMPLIANCE WITH THE SPECIFICATION 26 42

14.00 10, CATHODIC PROTECTION SYSTEMS (SACRIFICIAL ANODE), AND

ACCEPTABLE INDUSTRY STANDARDS. THE CONTRACTOR'S CORROSION

ENGINEER SHALL COORDINATE WITH THE CATHODIC PROTECTION ANODE

SUPPLIER AND THE GENERAL CONTRACTOR TO INSURE THAT OPERATION

OF THE GATE IS NOT HINDERED, IN ANY MANNER, DUE TO THE MOUNTING

LOCATIONS OF ANODES. ANY MODIFICATIONS TO THE CATHODIC

PROTECTION SYSTEM SHALL BE SUBMITED BY THE CONTRACTOR'S

CORROSION ENGINEER, VIA THE CONTRACTOR, TO THE GOVERNMENT FOR

APPROVAL, PRIOR TO ACCOMPLISHING THE WORK.

9. TWO (2) SPARE ANODES OF EACH TYPE SHALL BE FURNISHED PER GATE

LEAF.
