CONSISTS OF INSTALLING #18 DYWIDAG TIE RODS AND TUBE STEEL WALES. (NOTE: THE STATIONING GIVEN

ABOVE IS APPROXIMATE AND SHALL NOT BE USED TO DEFINE THE BULKHEAD LENGTH.) THE FOLLOWING

INSTRUCTIONS AND LIMITATIONS SHALL BE ENFORCED DURING THE PERFORMANCE OF THIS WORK.

SURCHARGE LOADING ON AREA WITHIN 56 FEET OF BULKHEAD SHALL BE LIMITED TO MINIMUM EQUIPMENT

REQUIRED TO PERFORM WORK. EXCAVATED MATERIAL MAY BE PLACED ADJACENT TO ANCHOR PILES A

MINIMUM OF FORTY FEET AWAY FROM BULKHEAD. NO OTHER STOCKPILING OF MATERIALS WILL BE

ALLOWED WITHIN FIFTY-SIX FEET OF BULKHEAD.

2. SEQUENCE OF WORK AT EXISTING PILES SHALL BE AS FOLLOWS (SEE SHEET S-503 FOR WORK AT BOAT

RAMP):

A. EXCAVATE FOR WORKING SPACE REQUIRED FOR INSTALLATION OF WALES, TIE RODS, AND ANCHOR

BEAMS. THIS EXCAVATION WORK NEED NOT BE LIMITED TO A GROUP OF TEN BULKHEAD PILES.

B. INSTALL WALES.

C. INSTALL ANCHOR BEAM, PROVIDING SHIMS AS REQUIRED. CONNECTION OF ANCHOR BEAM TO ANCHOR

PILES SHALL BE BY WELDING.

D. INSTALL TIE RODS. TIE RODS SHALL BE SUPPORTED AT EIGHT FOOT INTERVALS PRIOR TO ANY

TIGHTENING. HEX NUTS SHALL BE "SNUGGED TIGHT" TO ELIMINATE SLACK FROM TIE RODS. THE

CONTRACTOR SHALL ENSURE THAT TIE RODS ARE TIGHTENED IN A BALANCED MANNER AND THAT THE

CONNECTION OF THE ANCHOR BEAM TO THE ANCHOR PILES IS NOT DAMAGED BY TWISTING. DO NOT

DRIVE OVER TIE RODS PRIOR TO PLACING ONE LIFT OF BACKFILL, EXCEPT AS REQ'D BY A SMALL, TRACKED DOZER TO SPREAD BACKFILL SOIL AS LIMITED BY NOTE "H" BELOW.

E. BOTH TIE RODS IN A PILE GROUP SHALL BE CHECKED FOR TIGHTNESS AND ANCHOR BEAM

CONNECTION LOCK NUTS SHALL BE SECURELY TIGHTENED PRIOR TO BACKFILLING.

F. DRIVE, CUT, AND TACK WELD WASHOUT PROTECTION ANGLES.

G. PLACE GEOTEXTILE FABRIC ON SHORE SIDE OF BULKHEAD FROM TOP OF WALE TO TOP OF

GENERAL PIPE PILE BULKHEAD NOTES:

LAYOUT SHOWN HAS NOT BEEN SURVEYED. LAYOUT IS BASED ON THE APPROXIMATE METHOD OF USING AN AERIAL PHOTOGRAPH.

THERMOTUBE LOCATIONS SHOWN ARE APPROXIMATE AND THE ANCHOR PILES SHOWN HAVE BEEN PLACED ON THE DRAWINGS BASED

ON THE APPROXIMATE LOCATION OF THE THERMOTUBES. FINAL LAYOUT SHALL BE BASED ON THE RESULT OF THE CONTRACTOR'S

SURVEY WITH EXCAVATION AS REQUIRED TO LOCATE THE ANCHOR PILES.

EXISTING AS-BUILT INFORMATION INDICATES THAT EACH ANCHOR PILE GROUP (2 - 24"Ø x 30' LONG STEEL PIPE PILES, DRIVEN

SIDE-BY-SIDE BUT NOT ATTACHED TO EACH OTHER) SUPPORT TEN (10) BULKHEAD PILES (24"Ø x 40' LONG STEEL PIPE PILES, ALSO NOT

ATTACHED TO EACH OTHER). EXISTING TIE-BACKS ARE #7 REBAR IN A RADIAL PATTERN TO EACH BULKHEAD PILE (ASSUMED TO BE 5

PER ANCHOR PILE). EXISTING TIE-BACKS ARE AT +4' MLLW PER AS-BUILT INFORMATION.

AS-BUILT INFORMATION, AND FIELD INSPECTION OF A COUPLE OF ANCHOR PILE GROUPS THAT ARE EXPOSED, INDICATES THAT THE

THERMOTUBES ARE LOCATED BEHIND THE ANCHOR PILES, AS SHOWN. WHERE THERMOTUBE DOES NOT CONFLICT, PLACE ANCHOR

BEAM IN THE PREFERRED POSITION, BEHIND THE ANCHOR PILES.

NOTES:

1. STRUCTURAL WORK ON PILE GROUPS 1 THRU 7 (PG1 THRU PG7) IS NOT PART OF THIS CONTRACT.

2. THE CENTER OF THE FIRST PIPE PILE (CLOSEST TO STA 10+00) OF PILE GROUP 8 (PG8) IS LOCATED AT APPROXIMATELY SCL STA

EXISTING GAP.

c. ANCHOR PILES (2 GROUPS OF TWO) SHALL BE INSTALLED IN A SIMILAR FASHION TO EXISTING WORK.

d. PRIOR TO INSTALLATION AND TIGHTENING OF TIE RODS, FILL PLACED AGAINST THE NEW BULKHEAD PILES SHALL BE LIMITED

AS SHOWN ON SECTION A ON THIS SHEET.

e. ANCHOR BEAM SHALL BE PLACED IN THE PREFERRED POSITION, BEHIND THE ANCHOR PILES AS SHOWN.

f. TUBE STEEL WALE, ANCHOR BEAM, TIE RODS, WASHOUT PROTECTION ANGLE, GEOTEXTILE FABRIC, AND FILTER MATERIAL

BACKFILL SHALL BE CONSTRUCTED FOR PG15 THRU PG16 AS DETAILED ON SHEETS S-501 AND S-502.

g. AFTER TIE RODS ARE INSTALLED AND TIGHTENED, THE RAMP SHALL BE BACKFILLED TO MATCH ADJACENT GRADE ON EITHER

SIDE OF THE SHEET PILES.

h. PILE GROUPS 15 AND 16 DO NOT REQUIRE A THERMOTUBE.

2. PILE DRIVING TOLERANCES, CONDITIONS, AND DOCUMENTATION:

a. BULKHEAD PILES (PG15 AND PG16) SHALL BE DRIVEN TO WITHIN A HORIZONTAL TOLERANCE OF NO MORE THAN 2 INCHES, AT

THE TOP OF THE PILE, FROM THE STRAIGHT LINE POSITION DEFINED BY THE EXISTING ADJACENT PILES.

b. ANCHOR PILE TOPS SHALL BE TIGHT TO ONE ANOTHER AND MEET A 2" TOLERANCE FROM A LINE PARALLEL TO THE BULKHEAD

ALIGNMENT.

c. A VARIATION OF NO MORE THAN

INCH PER FOOT OF PILE LENGTH FROM THE VERTICAL WILL BE PERMITTED.

d. THE CONTRACTOR SHALL COORDINATE AND CONDUCT PIPE PILE INSTALLATION TAKING INTO ACCOUNT EXISTING B-ROCK THAT

MAY BE PRESENT WITHIN THE PG15 AND PG16 AREA (SEE NOTE 3 BELOW).

e. THE CONTRACTOR SHALL KEEP A COMPLETE AND ACCURATE RECORD OF EACH PILE DRIVEN. INDICATE PILE LOCATION, LENGTH, GROUND ELEVATION, WATER LEVEL, TIP ELEVATION, TOP AND/OR CUTOFF ELEVATION, PENETRATION IN SECONDS

PER FOOT (OR BLOWS PER FOOT IF AN IMPACT HAMMER IS REQUIRED) FOR THE ENTIRE LENGTH OF PENETRATION, HAMMER

DATA, AND NOTATIONS OF PILE BEHAVIOR DURING DRIVING. THE PILE RECORDS SHALL BE PROVIDED TO THE CONTRACTING

OFFICER'S REPRESENTATIVE WITHIN 7 DAYS AFTER PILE INSTALLATION.
