GENERAL NOTES:

1. ALL DETERIORATED CONCRETE SURFACES CONSISTING OF SPALLED OR HOLLOW

SOUNDING AREAS SHALL BE SOUNDED AND REPAIRED AS DESCRIBED IN THE DRAWINGS

AND SPECIFICATIONS USING EITHER POLYMER-MODIFIED CONCRETE OR PORTLAND

CEMENT CONCRETE, DEPENDING ON THE DEPTH OF THE REPAIR AREA. THIS APPLIES TO

THE FOLLOWING FEATURES:

A. CONCRETE SPILLWAY SLAB LOCATED DOWNSTREAM OF THE CONCRETE OGEE

SPILLWAY TO STA. 11+00.

B. CONCRETE TRAINING WALL FROM STA. 8+90 TO STA. 11+00.

2. ELEVATIONS ON SHEETS S-201 AND S-202 IDENTIFY THE AREAS OF CRACK REPAIR. ALL

CONCRETE WALL CRACKS 1/8" WIDE OR GREATER THROUGH THE SPILLWAY SHALL BE

REPAIRED USING A ONE-COMPONENT POLYURETHANE BASED, NON-SLAG/FLEXIBLE

INJECTION ADHESIVE, AS SPECIFIED. CLEAN ALL SURFACES. CRACK WALLS SHALL BE

SOUND, CLEAN, DRY, FROST-FREE, AND FREE OF OIL AND GREASE AND ANY OTHER

CONTAMINANTS. FOLLOW CRACK SEALANT MANUFACTURER'S RECOMMENDATIONS FOR

APPLICATION.

3. POLYMER-MODIFIED CONCRETE SHALL BE USED FOR REPAIR OF ALL PATCHES BETWEEN 2"

AND 6" IN DEPTH. POLYMER-MODIFIED CONCRETE PLACEMENT SHALL BE IN ACCORDANCE

WITH SPECIFICATION SECTION 03 01 32 "CONCRETE REHABILITATION FOR CIVIL WORKS".

REFER TO SHEET S-501 FOR ADDITIONAL DETAILS.

4. PORTLAND CEMENT CONCRETE SHALL BE USED FOR REPAIR OF ALL PATCHES 6" OR

GREATER IN DEPTH. CONCRETE PLACEMENT SHALL BE IN ACCORDANCE WITH

SPECIFICATION SECTION 03 30 53 "MISCELLANEOUS CAST-IN-PLACE CONCRETE". REFER TO

SHEET S-501 FOR ADDITIONAL DETAILS.

5. AREAS IDENTIFIED ON THE DRAWINGS AS EXHIBITING CONCRETE DETERIORATION AND ANY

DIMENSIONS SHOWN AT THOSE AREAS ARE APPROXIMATE. CONTRACTOR SHALL

DETERMINE THE LIMITS OF DETERIORATED CONCRETE BY VISUAL INSPECTION AND/OR

TAPPING WITH A HAMMER OR STEEL ROD AND LISTENING FOR DULL OR HOLLOW SOUNDS.

CONCRETE SURFACES SHALL BE SOUNDED A MINIMUM OF ONE FOOT BEYOND ALL EDGES

OF VISUALLY INSPECTED DETERIORATED AREAS TO VERIFY CONDITION.

6. CONSTRUCT AND INSTALL AN OUTLET DRAINAGE EXTENSION PIPE FOR 2 SCUPPER DRAINS.

REFER TO SHEETS S-502 AND S-503 FOR DETAILS.

7. SURVEY CONTROL POINTS/BENCHMARKS EXIST AT LOCATIONS NEAR THE DAM. THE

CONTRACTING OFFICERS REPRESENTATIVE CAN PROVIDE THE EXACT LOCATION OF THESE

ELEMENTS, IF NEEDED (SEE SHEET S-502 FOR THE BRIDGE PLAN VIEW).
