GENERAL NOTES:

1. TOP OF ROCK EXTENTS INTERPOLATED FROM AVAILABLE

BORINGS. TOP OF ROCK IS SCHEMATICALLY

REPRESENTED ON THE DRAWINGS AND MAY VARY FROM

WHAT IS SHOWN HERE.

2. TOP OF ROCK EXTENTS WITHIN THE P-310 BLASTING

OPTION FOOTPRINT DO NOT REFLECT AS-BUILT

CONDITIONS AND MAY VARY FROM WHAT IS SHOWN HERE.

3. EXCAVATION SUPPORT IMPROVEMENTS MUST BE

INSTALLED PRIOR TO EXCAVATION WITHIN THE LIMIT OF

INITIAL EXCAVATION FOR THE STRUCTURE TO BE

SUPPORTED. THE LIMIT OF INITIAL EXCAVATION EXTENDS

25 FEET FROM THE BERTH 11 CONCRETE BULKHEAD AND

40 FEET FROM THE BERTH 1 COPING.

4. THE EXCAVATION DIMENSIONS AND BASE OF EXCAVATION

ELEVATIONS SHOWN IN THE GENERAL EXCAVATION REFER

TO MINIMUM INSIDE CLEARANCE DIMENSIONS (FINISHED

DIMENSIONS). ELEVATIONS ARE IN NAVD88 DATUM.

5. A 2 FT OVEREXCAVATION BELOW THE FINISHED

DIMENSIONS IS THE MAXIMUM PERMITTED. LOCALLY

DEEPER EXCAVATIONS REQUIRED FOR DRY DOCK SLAB

AND SHAFT CONNECTIONS SHALL REMAIN WITHIN 2 FT

OVEREXCAVATION LIMITS UNLESS OTHERWISE APPROVED

BY THE CONTRACTING OFFICER. CONTRACTOR IS NOT

REQUIRED TO UTILIZE THE FULL OVEREXCAVATION

VOLUME AND SHALL ONLY OVEREXCAVATE THE MINIMUM

REQUIRED TO REACH THE EXCAVATION DEPTHS SHOWN

AND LOCAL EXCAVATIONS REQUIRED FOR DRY DOCK

CONSTRUCTION.

6. VOLUMES DEPICTED HERE ARE IN-PLACE CUBIC YARDS.

7. DRY DOCK EXCAVATION VOLUME TABLE CONTAINS

APPROXIMATE VOLUME OF SOIL AND ROCK BETWEEN

MUDLINE AND BASE OF EXCAVATION VALUES NOTED

WITHIN DRY DOCK FOOTPRINT.

8. BERTH 11 EXCAVATION VOLUME IS THE APPROXIMATE

VOLUME OF EXCAVATED MATERIAL BEHIND BERTH 11

NORTH OF THE BERTH 11/DRY DOCK EXCAVATION

BOUNDARY.

9. ENTRANCE STRUCTURE EXCAVATION VOLUME IS THE

APPROXIMATE VOLUME OF EXCAVATED MATERIAL WITHIN

THE DD1N ENTRANCE STRUCTURE FOOTPRINT. ENTRANCE

STRUCTURE EXCAVATION SHALL NOT PROCEED UNTIL

INSTALLATION OF EXCAVATION SUPPORT AND WEST

CLOSURE WALL REMOVAL.

10. A TURBIDITY CURTAIN IS REQUIRED IN FRONT OF EXISTING

ASW INTAKE DURING EXCAVATION THAT OCCURS PRIOR

TO COMMISSIONING OF THE TEMPORARY ASW SYSTEM. A

TURBIDITY CURTAIN WILL ALSO BE REQUIRED ACROSS

ANY OPENINGS IN THE WEST CLOSURE WALL OR DD1W

ENTRANCE STRUCTURE DURING TIMES WHEN EXCAVATION

IS ONGOING.

11. EXCAVATION WILL NOT BE NEEDED WITHIN THE P-310

BLASTING OPTION FOOTPRINT. LIMITS OF P-381

EXCAVATION DO NOT REFLECT AS-BUILT CONDITIONS

FROM P-310 AND MAY VARY FROM WHAT IS SHOWN HERE.

GENERAL NOTES:

1. WORK THIS DRAWING WITH BE102, BE103, BE201, BE202

AND BE204.

2. TOP OF ROCK SURFACE INTERPOLATED FROM AVAILABLE

BORINGS AND ALSO INCOPORATES ROCK BLASTING

OPTIONS AWARDED TO P-310. TOP OF ROCK IS

SCHEMATICALLY REPRESENTED ON THE DRAWINGS AND

MAY VARY FROM WHAT IS SHOWN HERE.

3. EXCAVATION SLOPES SHALL BE LAID BACK SUCH THAT

THE SLOPES ARE STABLE.

4. EXCAVATION FOR THE P-310 BID OPTIONS IS 2 FEET

LOWER THAN THE REQUIRED BASE OF EXCAVATION TO

ACCOUNT FOR LOCAL EXCAVATIONS FOR DRY DOCK SLAB

AND SHAFT CONNECTIONS WITHIN P-381. CONTRACTOR

MAY PERFORM ADDITIONAL EXCAVATION TO SUPPORT

MEANS AND METHODS FOR DRY DOCK CONSTRUCTION. IT

IS ANTICIPATED THAT THE P-310 CONTRACTOR WILL

SUBDRILL THEIR BLAST HOLES BELOW THE ELEVATIONS

SHOWN, WHICH WILL RESULT IN A VARIABLE GROUND

SURFACE. IT IS ANTICIPATED THAT THE UPPER PORTION

OF THE MATERIAL IN THIS AREA WILL CONTAIN A MIXTURE

OF INTACT ROCK AND FRAGMENTED ROCK RESULTING

FROM BLASTING (SHOT-ROCK).

5. MECHANICAL ROCK REMOVAL REQUIRED TO EL -46.43

WHERE INITIAL EXCAVATION LIMIT OF 40' RESTRICTED

ROCK BLASTING IN FRONT OF BERTH 1.

GENERAL NOTES:

1. SPACING FOR BERTH 1 SECANT PILE VARIES BETWEEN K1

THRU K5 AND K87 THRU K95.

2. EXISTING PZC18 STEEL SHEET PILE WALL AND CONCRETE

ON BACKSIDE OF SHEET PILE WALL MAY BE USED AS

FORMWORK FOR SECANT PILE WALL CONSTRUCTION.

EVALUATE STABILITY OF PZC18 STEEL SHEET PILE WALL

DURING PILE CONSTRUCTION AND PROVIDE TEMPORARY

SHORING AS NEEDED.

3. IN THE AREA WHERE THE SECANT PILE WALL EXTENDS

BEYOND THE EXISTING STEEL SHEETS, REMOVE THE

STEEL SHEETS WITHIN SECANT PILE ALIGNMENT AND

INSTALL FORMWORK, TEMPLATES, AND/OR SHORING TO

CONSTRUCT PILES K1 THRU K4.

4. BERTH 1 SECANT PILE WALL SHALL BE CUT DOWN TO A

FINAL TOP ELEVATION OF EL 8.7 AFTER COMPLETION OF

DRY DOCK CONSTRUCTION FOR CONCRETE DECK

PLACEMENT.

5. NOTED SECANT PILE(S) SHALL BE CUT DOWN TO A FINAL

TOP ELEVATION OF APPROXIMATELY EL 6 AFTER

COMPLETION OF DRY DOCK CONSTRUCTION FOR UTILITY

CROSSING.
