NOTES:

1. ESTIMATED BOND LENGTH IS 30.0' FOR BIDDING PURPOSES.

2. DETAILS 1 AND 2 ON THIS SHEET ARE GENERIC AND FOR ILLUSTRATION PURPOSES ONLY. CONTRACTOR SHALL DESIGN, CONSTRUCT AND TEST ALL SOIL ANCHORS IN ACCORDANCE WITH THE PROJECT SPECIFICATIONS.

3. SOIL ANCHOR DESIGN SHALL BE PERFORMED AND SEALED BY A FLORIDA-LICENSED SPECIALTY ENGINEER

RETAINED BY THE CONTRACTOR.

4. CONTRACTOR MAY SELECT EITHER TENDON OR BAR ANCHORAGE SYSTEMS TO BE USED EXCLUSIVELY

THROUGHOUT THE PROJECT.

5. LOCK OFF LOAD SHALL BE EQUAL TO 54 KIPS.

6. HEAD COVERS ARE REQUIRED TO PROTECT ANCHOR HEADS AGAINST CHLORIDE INTRUSION DURING CONSTRUCTION AND SHALL BE INSTALLED AND FILLED WITHIN 24 HOURS FOLLOWING LOCK OFF.

7. BEARING PLATES AND STRUCTURAL ANCHORAGE COMPONENTS AS DETAILED ARE DESIGNED FOR ONE EQUALLY-SIZED ANCHORS AT THE SPACINGS INDICATED, WITH A MAXIMUM APPLIED LOAD EQUAL TO 162 KIPS.

8. LOAD TESTING SHALL NOT BE CONDUCTED UNTIL THE CONCRETE AND GROUT HAS REACHED A MINIMUM 70% OF

THE SPECIFIED COMPRESSIVE STRENGTH.

9. CASING GREATER THAN 8" OUTER DIAMETER REQUIRES ENGINEER APPROVAL.
