GENERAL NOTES

1. VERIFY LOCATIONS OF ALL UTILITIES PRIOR TO COMMENCING WORK.

REPRESENTATIVES FROM THE RESPECTIVE UTILITY COMPANIES MUST BE

NOTIFIED IN ACCORDANCE WITH STATE LAW. CALL UNDERGROUND

SERVICE ALERT TOLL FREE 1-800-227-2600 AT LEAST TWO WORKING DAYS

BEFORE EXCAVATION.

2. LOCATIONS AND ELEVATIONS OF UNDERGROUND OR EXPOSED EXISTING

STRUCTURES AND UTILITIES ARE NOT WARRANTED TO BE EXACT, NOR IS IT

WARRANTED THAT ALL UNDERGROUND OR EXPOSED STRUCTURES AND

UTILITIES ARE SHOWN. RECORD ALL UNDERGROUND OR EXPOSED

STRUCTURES OR UTILITY INFORMATION AND INCLUDE IN THE RECORD

DRAWINGS.

3. CONTRACTOR IS RESPONSIBLE FOR DESIGN, IMPLEMENTATION, OPERATION

BY THE EXISTING OUTLET WORKS. CONTRACTOR IS RESPONSIBLE FOR

CONTROL OF WATER FOR THE DURATION OF THE PROJECT.

5. LOCATIONS OF EXISTING FEATURES SHOWN ON THE DRAWINGS ARE

APPROXIMATE. CONFIRM LOCATIONS AS REQUIRED TO COMPLETE THE

WORK. IMMEDIATELY NOTIFY COR OR BIA REPRESENTATIVE OF ANY

DISCREPANCIES.

6. LIMIT CONSTRUCTION ACTIVITY TO THE PROJECT CONSTRUCTION LIMITS

SHOWN ON THE DRAWINGS OR ALLOWED BY THE COR OR BIA

REPRESENTATIVE. RESTORE ALL DAMAGED AREAS TO CONDITIONS EQUAL

OTHERWISE IN DRAWINGS OR PROJECT SPECIFICATIONS.

1.2. DETAIL BARS IN ACCORDANCE WITH THE LATEST EDITIONS OF PUBLICATION

SP-66: “ACI DETAILING MANUAL” WITH ADDED REQUIREMENTS OF THE

PROJECT SPECIFICATION AND ACI 318: “BUILDING CODE REQUIREMENTS

FOR STRUCTURAL CONCRETE.”

1.3. DETAILING SHALL FOLLOW THE RECOMMENDATIONS OF ACI 315 UNLESS

OTHERWISE SHOWN. NO CHANGES SHALL BE MADE WITHOUT PRIOR

APPROVAL.

1.4. PLACE REINFORCEMENT IN ACCORDANCE WITH APPROVED

REINFORCEMENT SHOP DRAWINGS. IN THE EVENT OF A CONFLICT

BETWEEN THESE DRAWINGS AND THE APPROVED SHOP DRAWINGS, THE

APPROVED SHOP DRAWINGS SHALL GOVERN.

1.5. REINFORCEMENT PROTECTION:

1.5.1. REINFORCING COVER: SEE TABLE.

1.5.2. SEE ACI 318-11 7.5 AND ACI 301, SECTION 6.3 FOR REINFORCEMENT

PLACING TOLERANCES AND ACI 117 FOR ADDITIONAL REQUIREMENTS.

1.6. PROVIDE ACCESSORIES NECESSARY TO PROPERLY SUPPORT

REINFORCING AT POSITIONS SHOWN ON PLANS. THE RECOMMENDATIONS

OF ACI 315 (DETAILING MANUAL) SHALL BE USED IN SELECTING

ACCESSORIES.

1.7. ALL REINFORCING, DOWELS, BOLTS, AND EMBEDDED PLATES SHALL BE SET

AND TIED IN PLACE BEFORE THE CONCRETE IS PLACED. “STABBING” INTO

PREVIOUSLY PLACED CONCRETE IS NOT PERMITTED.

1.8. BEFORE PLACING CONCRETE, CHECK ALL APPLICABLE DRAWINGS

RELEASED AS SUITABLE FOR CONSTRUCTION INCLUDING

MANUFACTURER'S DRAWINGS TO VERIFY THE PRESENCE OF ALL

EMBEDDED MATERIAL REQUIRED IN THE PLACEMENT.

1.9. REINFORCEMENT MAY BE ADJUSTED IN THE FIELD TO CLEAR FORM TIES

AND ANCHOR BARS. IN SUCH CASES, RELOCATION OF THE EMBEDDED

MATERIALS MUST BE CONSIDERED. IN NO CASE SHOULD BARS BE BENT IN

THE FIELD.

1.10.WHERE POSSIBLE, REINFORCEMENT SHALL BE PLACED TO MAINTAIN A

CLEAR DISTANCE OF AT LEAST 1 INCH BETWEEN OTHER REINFORCEMENT,

ANCHOR BOLTS, FORM TIES, OR OTHER EMBEDDED METALWORK.

REINFORCEMENT PARALLEL TO ANCHOR BOLTS OR OTHER EMBEDDED

METAL WORKS SHALL BE PLACED TO MAINTAIN A CLEAR DISTANCE OF AT

LEAST 1-1/3 TIMES THE MAXIMUM SIZE AGGREGATE TO BE USED.
