1. PRIMARY PROJECT SCOPE ITEMS:

1.1. REPLACE/REFURBISH HYDRAULIC CYLINDER/GATE ASSEMBLY COMPONENTS FOR EACH INDIVIDUAL GATE AS SPECIFIED IN TABLE 1.1 ON DRAWING M301. BOTH GATES WILL BE

ADDRESSED AS PART OF THIS PROJECT AND ONLY ONE GATE WILL BE ALLOWED TO BE OUT OF SERVICE AT ANY GIVEN TIME DURING THE CONSTRUCTION PROJECT.

1.2 REPLACE HYDRAULIC PRESSURE GAUGES LOCATED AT OPERATOR'S STATION (2 GAUGES) AND AT THE HYDRAULIC OIL PUMP RESERVOIR (1 GAUGE). REFER TO SHEET M302 FOR

ADDITIONAL INFORMATION.

1.3 REPLACE 4-WAY CONTROL VALVES AT THE MAIN OPERATOR'S STATION FOR BOTH GATES. NEW CONTROL VALVES SHALL HAVE CONTROL LEVERS THAT AUTOMATICALLY RETURN

TO NEUTRAL POSITION WHEN THE CONTROL LEVER IS RELEASED BY THE OPERATOR, TO STOP GATE MOVEMENT WHEN THE LEVER IS NOT ENGAGED.

1.4 REPLACE COMPLETE DIGITAL GATE MONITORING SYSTEM, INCLUDING BUT NOT LIMITED TO, THE CABLE EXTENSION TRANSDUCERS AND AND THE DIGITAL POSITION DISPLAYS AND

ALL WIRING AND OTHER COMPONENTS REQUIRED FOR A COMPLETE AND FUNCTIONAL POSITION INDICATION SYSTEM. CONFIRM EXISTING ELECTRICAL POWER CONNECTION FOR

ALL COMPONENTS WILL BE SUFFICIENT AND CODE COMPLIANT FOR RECONNECTION AND POWERING OF NEW SYSTEM. CONTRACTOR TO COMPLETE INITIAL SETUP AND CALIBRATE

ALL COMPONENTS OF THE NEW SYSTEM. REFER TO SHEET M302 FOR ADDITIONAL INFORMATION.

2. THE SITE CURRENTLY HAS EXISTING STOP LOGS THAT MAY BE USED BY THE CONTRACTOR AND ARE COMPATIBLE WITH THE EXISTING STOP LOG CHANNELS. THE CONTRACTOR SHALL

EITHER UTILIZE EXISTING STOP LOGS OR FURNISH NEW STOP LOGS TO BE INSTALLED IN EXISTING STOP LOG SYSTEM FOR ONE TYPICAL GATE. CONTRACTOR IS RESPONSIBLE FOR

ASSESSING THE CONDITION OF THE EXISTING STOP LOG CHANNELS AND STOP LOGS TO ENSURE SAFE AND PROPER OPERATION. CONTRACTOR IS RESPONSIBLE FOR PROVIDING

CALCULATION SHOWING STOP LOG SYSTEM IS CAPABLE OF WITHSTANDING 212 FT OF HYDRAULIC HEAD WITH APPLICABLE SAFETY FACTORS AS CALCULATED BY A PROFESSIONAL

ENGINEER AND SUBMITTED FOR APPROVAL. CONTRACTOR IS RESPONSIBLE FOR DEVELOPING PLANS AND REQUIRED MEANS TO INSERT AND REMOVE STOP LOGS FOR DEWATERING

DURING CONSTRUCTION.

3. CONTRACTOR MUST PROVIDE HOIST, CRANE, OR OTHER LIFTING DEVICE TO PLACE AND REMOVE STOP LOGS, BUT THIS LIFTING DEVICE WILL NOT BE RETAINED BY THE GOVERNMENT

AFTER CONSTRUCTION.

4. THE TOWER HAS AN EXISTING 10 TON ELECTRIC WIRE ROPE HOIST THAT IS LOCATED ABOVE THE GENERATOR FLOOR AND CAN BE USED BY THE CONTRACTOR. CONTRACTOR WILL BE

RESPONSIBLE FOR DEVELOPING A PLAN AND PROCEDURE FOR UTILIZING THE EXISTING HOIST AS LIFTING MEANS TO PERFORM THE PROPOSED WORK ON THE HYDRAULIC

CYLINDERS/GATE ASSEMBLIES. CONTRACTOR WILL BE RESPONSIBLE FOR COMPLETING ANY LOAD TESTING AND CERTIFICATION REQUIRED FOR SAFE USE OF THE CRANE SYSTEM.

REPLACE ALL CYLINDER GASKETS AND STEM O-RINGS. TEST EXISTING HYDRAULIC FLUID TO PERFORM A THOROUGH ANALYSIS OF THE CONDITION OF THE FLUID.

REFER TO LIST BELOW FOR DETAILED DIRECTION ON INDIVIDUAL COMPONENTS.

NOTE: POLISHING AND HONING CONDUCTED AS PART OF REFURBISHMENT EFFORT WILL REQUIRE NEW PACKING GLANDS, PACKING SEATS, PACKINGS AND OTHER

COMPONENTS TO HAVE MODIFIED DIMENSIONS FROM ORIGINAL DESIGN DIMENSIONS. DIMENSIONS OF NEW COMPONENTS SHALL MATCH THE ORIGINAL DESIGN

CLEARANCES AND TOLERANCES AFTER TAKING INTO ACCOUNT THE REVISED DIMENSIONS OF THE REFURBISHED STEMS RODS.

*REFER TO MECHANICAL DETAIL DRAWINGS AND "FOR INFORMATION DRAWINGS" FOR DETAILS OF COMPONENTS INCLUDING MATERIAL TYPE, MATERIAL SPECIFICATIONS AND

OTHER ADDITIONAL DETAILS. THE COMPONENT MARKS LISTED BELOW CORRESPOND TO THE ORIGINAL AS-BUILT SHEET FOLLOWED BY THE PART NUMBER OF THE

COMPONENT SHOWN OR LISTED ON THAT SHEET. ALL EXISTING COMPONENTS LISTED TO BE REFURBISHED AND REUSED SHALL BE THOROUGHLY CLEANED AND HAVE VISUAL

INSPECTIONS/ASSESSMENTS CONDUCTED. AN ASSESSMENT REPORT SHALL BE PRODUCED AND DELIVERED TO COR PER THE SPECIFIED REQUIREMENTS. THE CONTRACTOR
