GENERAL NOTES FOR CONVENTIONAL CONCRETE:

1. ALL STRUCTURAL CONCRETE SHALL BE f'c=4500 PSI. ALL CONCRETE SHALL ALSO BE AIR ENTRAINED (5 TO 8%) AND HAVE A

MAXIMUM SLUMP OF 5 INCHES WITHOUT WATER REDUCING ADMIXTURE AND 6.5 INCHES MAXIMUM WITH WATER REDUCING

ADMIXTURE.

2. CONCRETE SHALL BE PREPARED, PLACED, AND CURED IN ACCORDANCE WITH THE REQUIREMENTS ADOPTED BY THE AMERICAN

CONCRETE INSTITUTE (ACI) AND LOCAL CODES.

3. ALL CONCRETE SHALL CONFORM TO THE MOST RECENT EDITION OF "CODE REQUIREMENTS FOR ENVIRONMENTAL ENGINEERING

CONCRETE STRUCTURES, ACI-350."

4. FOR REINFORCING STEEL

4.1. FOR DEVELOPMENT AND LAP SPLICE LENGTH, REFER TO ACI 318 AND ACI 350.

4.2. REINFORCEMENT SHALL HAVE A MINIMUM LENGTH OF 20'-0" BETWEEN SPLICES UNLESS OTHERWISE SHOWN.

4.3. SPLICES SHALL NOT CROSS CONSTRUCTION OR CONTRACTION JOINTS.

4.4. SPLICE DIMENSIONS SHOWN ARE MINIMUM VALUES. CONTRACTOR MAY ELECT TO UTILIZE LONGER SPLICE LENGTHS TO

ACCOUNT FOR POTENTIAL CONSTRUCTION VARIANCES AT NO ADDITIONAL COST TO THE OWNER.

4.5. REINFORCING STEEL SPLICES NOT SHOWN ON THESE DRAWINGS SHALL BE SHOWN ON THE SHOP DRAWINGS AND

APPROVED BY THE ENGINEER IN ACCORDANCE WITH THE SPECIFICATIONS. LOCATE SPLICES AT POINT OF MINIMUM STRESS.

4.6. SHALL BE DEFORMED BILLET STEEL BARS CONFORMING TO ASTM 615, 60 KSI YIELD GRADE.

5. MAINTAIN MINIMUM CONCRETE COVER AROUND REINFORCING STEEL AS FOLLOWS, UNLESS OTHERWISE INDICATED ON THE

DRAWINGS:

OGEE CREST - 3"

SPILLWAY SLAB - 2"

ENDSILL - 21

2"

6. CHAMFER ALL EXPOSED EDGES, HORIZONTAL, TOP, AND VERTICAL JOINTS IN THE END SILL 1 12" UNLESS INDICATED ON THE

DRAWINGS.

7. PROVIDE CONSTRUCTION, CONTRACTION, AND EXPANSION JOINTS AS INDICATED ON THE DRAWINGS, OR AS DIRECTED BY THE ENGINEER. CONTRACTION JOINTS HAVE NO REINFORCING THROUGH THE JOINTS AND THE CONCRETE SURFACES ARE

UNBONDED.

8. EMBEDDED MATERIAL - BEFORE PLACING CONCRETE, CARE SHALL BE TAKEN THAT ALL EMBEDDED ITEMS ARE IN POSITION AND

SECURELY FASTENED IN PLACE.

GENERAL NOTES

1. THE TOPOGRAPHIC INFORMATION SHOWN ON THESE PLANS WAS CREATED USING AIRBORNE TOPOGRAPHIC

LIDAR DATA COLLECTED IN 2014 AND 2015 AS PART OF THE CACHE OK QL2 LIDAR PROGRAM. THE DATA WAS PROVIDED AS LAS POINT FILES AND AS A DIGITAL ELEVATION MODEL (DEM) IN THE FOLLOWING DATUMS:

HORIZONTAL: NAD83, UTM ZONE 14, METERS ; VERTICAL: NAVD88 (GEOID 12A), METERS. THIS DATA WAS PROJECTED TO THE HORIZONTAL DATUM: NAD 1927 STATE PLANE OKLAHOMA SOUTH FIPS 3502, FEET. THE

DATA WAS CONVERTED FROM THE VERTICAL DATUM NAVD88 TO NGVD29 USING NOAA'S VERTCON

APPLICATION. THE ESTIMATED CONVERSION IS AS FOLLOWS: NGVD29 = NAVD88 - 0.171M.

2. CONTOURS SURROUNDING THE DAM WERE INTERPOLATED FROM LIDAR LAS POINT DATA (ONLY LAST RETURNS). OTHER CONTOURS WERE INTERPOLATED FROM LIDAR DEM DATA AS IDENTIFIED ON DRAWING 5.

3. BATHYMETRIC SURVEY PERFORMED BY SURVEY AND MAPPING, LLC IN 2017. THE EXTENT OF THE BATHYMETRY

CONTOURS IS IDENTIFIED ON DRAWING 5.

4. VERTICAL CONTROL FOR THE PROJECT IS BASED ON THE TOP OF DAM CREST, WHICH IS EL 1830.5.

HORIZONTAL CONTROL FOR THE PROJECT IS BASED ON THE UPSTREAM EDGE OF THE NONOVERFLOW SECTION OF THE EXISTING DAM WITH THE RIGHT EDGE OF THE CENTER AUXILIARY SPILLWAY AT PROJECT

BASELINE STATION 11+30.

5. THE LOCATION OF THE EXISTING DAM IN REFERENCE TO THE CONTOURS WAS ESTIMATED USING LIDAR LAS POINT DATA. IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO SURVEY THE PROJECT BASELINE, PRE-CONSTRUCTION, INTERMEDIATE, AND AS-CONSTRUCTED CONDITIONS AS DESCRIBED IN THE

SPECIFICATIONS.

6. THE EXISTING DAM GEOMETRY WAS ESTIMATED FROM PHOTOGRAPHS AND THE FOLLOWING SOURCES:

6.1. MODIFICATIONS TO GRAMA DAM AND COMANCHE DAM RECORD DRAWINGS BY GEI DATED 3/14/00

6.2. TEST BORING LOCATION PLAN BY STONE & WEBSTER ENGINEERING CORP DATED JULY 1990

6.2. TEST BORING LOCATION SECTIONS BY STONE & WEBSTER ENGINEERING CORP DATED JULY 1990

6.3. REHABILITATION OF COMANCHE DAM AS BUILT DRAWINGS BY USFWS DATED 2/1/88

6.4. FINAL REPORT PHASE II STUDY COMANCHE DAM REHABILITATION BY HANSON ENGINEERS INCORPORATED

OCTOBER 1986

6.5. DRAFT FIELD INVESTIGATIONS REPORT FOR COMANCHE DAM BY GEI CONSULTANTS, INC DATED

SEPTEMBER 1, 1995

6.6. 100% SUBMITTAL COMANCHE DAM FIELD INVESTIGATIONS REPORT BY GEI CONSULTANTS, INC DATED JULY

30, 1997.

7. IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO PERFORM WORK IN ACCORDANCE WITH ALL LOCAL, STATE, AND FEDERAL REGULATIONS.

8. CALL BEFORE YOU DIG! CONTRACTOR SHALL CONTACT 811 AT LEAST 3 DAYS PRIOR TO ANY EXCAVATION.

9. THE CONTRACTOR IS RESPONSIBLE FOR MAINTAINING THE RESERVOIR LEVEL THROUGHOUT THE WORK.

10. REFERENCES TO "LEFT" AND "RIGHT" WITHIN THESE PLANS ASSUME ONE IS LOOKING DOWNSTREAM.

NOTES:

1. VERTICAL, TRANSVERSE CONTRACTION JOINTS (C.J.) SHALL BE STAGGERED AT ALTERNATING DAM VERTICAL MONOLITHS.

2. CONTRACTION JOINTS SHALL CONSIST OF PLACEMENT OF A DOUBLE LAYER OF WOVEN POLYPROPYLENE GEOTEXTILE OR 14 GAUGE GALVANIZED STEEL PLATES DRIVEN INTO EACH RCC LIFT, FOLLOWING COMPACTION, AS SHOWN. IF GEOTEXTILE IS USED, CONTRACTOR SHALL SUBMIT PROPOSED INSTALLATION METHOD TO ENGINEER FOR REVIEW AND

APPROVAL.

2. TREATMENT SHALL BE CONSIDERED AS FOUNDATION TREATMENT AND SHALL BE EXCLUDED FROM ROCK EXCAVATION.

3. REFER TO TECHNICAL SPECIFICATIONS FOR ADDITIONAL REQUIREMENTS FOR FOUNDATION TREATMENTS.

NOTES:

1. VERTICAL IMMERSION VIBRATION DEPTH SHALL BE 20"± TO PENETRATE PREVIOUS RCC LIFT PROVIDED

THE PREVIOUS HAS NOT UNDERGONE INITIAL SET.
