NOTES (SEE G-002 FOR ABBREVIATIONS):

1. FOUR PIPE PILES JUST UPSTREAM OF THE ANGLE POINT IN THE SEAWALL

(STA. 15+20± SCL) WERE RESET IN APRIL OF 2000. REPAIRS INCLUDED

INSTALLING: 1) A 16' LONG, HSS 10x6x1/2 WALE W/ WALE TO PILE

CONNECTIONS SIMILAR TO DETAILS SHOWN IN THIS CONTRACT; 2) TWO 2

3/4"Ø A36 TIE RODS W/ TURNBUCKLES AND A WELDED-LAPPED SPLICE; 3) A 7'

LONG, HSS 12x8x1/2 ANCHOR BEAM PLACED BEHIND THE ANCHOR PILES; AND

4) PILE TOPS WERE TACK WELDED TOGETHER TO HOLD THEM IN ALIGNMENT

PRIOR TO INSTALLING WALE. THE WALE, TIE- BACK AND ANCHOR BEAM WERE

INSTALLED AT APPROX +5' MLLW. CONTRACTOR SHALL REMOVE AND

PROPERLY DISPOSE OF ALL ELEMENTS OF THIS PREVIOUSLY INSTALLED

TIE-BACK SYSTEM THAT CONFLICT WITH THE INSTALLATION OF THE TIE-BACK

SYSTEM SHOWN IN THIS CONTRACT.

2. TWENTY-FOUR (24) PILES IN THIS AREA HAVE SUBSIDED. ALIGNMENT OF THE

PILES REMAINS TYPICAL OF OTHER SECTION OF THE BULKHEAD, HOWEVER

THE TOP OF PILE ELEVATIONS FORM A SAG CURVE WITH A MAXIMUM

DISPLACEMENT OF APPROX 2.25'. CONTRACTOR SHALL WELD EXTENSIONS

ON EXISTING PILES TO PROVIDE A UNIFORM TOP OF PILE ELEVATION.

EXISTING PILES HAVE SOME DENTS IN THE TOP EDGE. CUT (E) PILES DOWN

AND STRAIGHTEN TO REMOVE DENTS AS REQUIRED TO PROVIDE A

CONTINUOUS WELD BETWEEN THE EXISTING PILE AND THE NEW SECTION OF

MATCHING PILE. TWO LENGTHS (APPROX 60') OF 24" CITY OF BETHEL. PIPE

BULKHEAD. THE CONTRACTOR SHALL REMOVE THESE TWO SECTIONS OF

PIPE PILE AND STAGE THEM ALONG THE BULKHEAD FOR REMOVAL BY
