About this file

Written by GovTribe AI · Dec 28, 2023

This federal solicitation seeks maintenance and improvement dredging services for the Portsmouth Harbor navigation project in New Hampshire and Maine. The scope of work involves removing approximately 2,300 cubic yards of ordinary material from the channel and turning basin, as well as 674,800 cubic yards of ordinary material and 14,700 cubic yards of hard rock material to expand the existing 35-foot deep turning basin. Dredging will be performed using mechanical dredging equipment and scows, with disposal at four sites - the Isle of Shoals North Disposal Site for all hard rock and some ordinary material, the Salisbury and Newbury Nearshore Disposal Sites for additional ordinary material, and placement as beach fill at Nantasket Beach for the remainder. The solicitation was issued by the Department of the Army Corps of Engineers New England District.

GENERAL NOTES:

1. LEGEND, GENERAL NOTES, SOUNDINGS AND BENCHMARK DATA, AND ALL OTHER INFORMATION SHOWN AND

NOTED ON THIS SHEET APPLY TO SHEETS G-002, C-101, C-301, AND C-302.

2. SOUNDINGS ARE IN FEET AND TENTHS. THE REFERENCE PLANE IS MEAN LOWER LOW WATER (MLLW) AND IS

BASED ON THE 1983-2001 TIDAL EPOCH. SOUNDINGS NOTED WITH A (+) ARE ABOVE THE REFERENCE PLANE OF

MLLW. SOUNDINGS WITHOUT A SIGN ARE BELOW THE REFERENCE PLANE OF MLLW, AND SHOULD BE

CONSIDERED NEGATIVE.

3. TOPOGRAPHY SHOWN IS FROM PREVIOUS SURVEYS, AERIAL IMAGERY AND/OR NOAA CHART NO. 13285. ALL

TOPOGRAPHY, INCLUDING SHORELINE, BRIDGES, PIERS, ETC., IS LOCATED APPROXIMATE UNLESS OTHERWISE

NOTED AND SHOULD BE USED AS A GENERAL REFERENCE ONLY.

4. BENCHMARK DATA: TIDES WERE RECORDED USING RTK GPS. THE MLLW TO NAVD88 CORRECTION FOR THIS

PROJECT IS 3.93 FEET TO 5.00 FEET. A KTD FILE WAS CREATED BASED ON PUBLISHED NOAA BENCHMARKS AT

COCHECO RIVER (STATION ID: 8420411), ATLANTIC TERMINALS T14A (STATION ID: 8423005), AND FORT POINT

(STATION ID: 8423898) ALONG PORTSMOUTH HARBOR AND PISCATAQUA RIVER, NEW HAMPSHIRE. THE

CORRECTIONS ARE 3.93 FEET FOR COCHECO RIVER, 3.99 FEET FOR ATALANTIC TERMINAL, AND 5.00 FEET FOR

FORT POINT. NAVD88 IS ABOVE MLLW. THEREFORE, THE CORRECTION SHOULD BE ADDED TO NAVD88 TO

CONVERT TO MLLW. NO TIDE GAUGES WERE USED ON THIS PROJECT. THE MEAN HIGH TIDE IS 7.0 FT ABOVE

MLLW AT ATLANTIC TERMINAL.

5. COORDINATES SHOWN ARE BASED ON THE TRANSVERSE MERCATOR GRID SYSTEM FOR THE STATE OF MAINE

(WEST ZONE 1802), NAD 1983 AND ARE BASED ON U.S. SURVEY FEET.

6. SURVEY WAS PERFORMED IN FEBRUARY 2021 USING AN R2 SONIC 2024 MULTIBEAM SONAR SYSTEM OPERATING

AT 300 KHZ. HORIZONTAL POSITIONING AND REAL TIME TIDE READINGS WERE RECORDED UTILIZING A TRIMBLE

SPS 855 GPS SYSTEM. THE RTK BASE STATION USED WAS STATION BASIN (2017), ELEVATION 14.24 FEET

(NAVD88). FIELD BOOK: R&H 4139; SURVEYED BY: MICHAEL VADNAIS AND CREW; REFER TO SURVEY NO.

NH_01_PIS_20210224_CS_10.

7. THE SOUNDING INFORMATION SHOWN ON THESE PLANS REPRESENTS THE SHOALEST SOUNDINGS OF THOSE

OBTAINED FROM HYDROGRAPHIC SURVEYS CONDUCTED DURING FEBRUARY 2021. THE DATA DEPICTED ON THIS

MAP SHOULD NOT BE USED FOR VOLUME CALCULATION PURPOSES.

8. THERE ARE NUMEROUS CABLE CROSSINGS ALONG THE CHANNEL ROUTE FROM HARBOR ENTRANCE TO

TURNING BASIN. CHECK NAVIGATIONAL CHARTS AND VERIFY ALL CABLE CROSSINGS.

9. THE INFORMATION DEPICTED ON THESE PLANS REPRESENTS THE RESULTS OF SURVEYS MADE ON THE DATES

INDICATED, AND CAN ONLY BE CONSIDERED AS INDICATING THE CONDITIONS EXISTING AT THAT TIME.

10. REFER TO SPECIFICATION SECTION 00 32 00 (GEOTECHNICAL DATA) FOR DEFINITIONS OF ORDINARY AND HARD

(ROCK) MATERIALS.

11. HARD (ROCK) MATERIAL ELEVATIONS AND AREA ESTABLISHED BY GZA GEOENVIRONMENTAL INC. IN OCTOBER

2016. REFER TO SPECIFICATION SECTION 00 32 00 (GEOTECHNICAL DATA) FOR DETAILS ON HOW TO OBTAIN

BORING DATA INCLUDED WITH GEOTECHNICAL REPORT.

12. AREA OF HARD (ROCK) MATERIAL SHOWN ON C-101 IS OVERLAYED WITH ORDINARY MATERIAL.

13. FOR INFORMATION PERTAINING TO HARD (ROCK) MATERIAL, REFER TO PARAGRAPH "MATERIALS TO BE

DREDGED" IN SPECIFICATION SECTION 35 20 23 (MECHANICAL DREDGING).

14. THE AREA BOUNDED BY COORDINATE DESIGNATIONS 37, A, B, C, D, 39, 38, AND 37 IS CONSIDERED THE

TURNING BASIN EXPANSION AREA FOOTPRINT (OR TOE OF SLOPE) AT -35 FEET MLLW.

15. ENTRANCE TO 35-FOOT TURNING BASIN IS APPROXIMATELY 5.1 NAUTICAL MILES (5.9 MILES/9.5 KM) ALONG

CHANNEL CENTERLINE FROM 35-FOOT CHANNEL ENTRANCE. FOR DISTANCE FROM CHANNEL ENTRANCE TO

DISPOSAL SITES REFER TO SPECIFICATION SECTION 35 20 23 (MECHANICAL DREDGING).

16. VERTICAL CLEARANCES ARE FROM THE MEAN HIGH WATER (MHW) LINE TO THE BOTTOM CHORD OF THE LIFT

TRUSS (MEMORIAL BRIDGE AND SARAH MILDRED LONG BRIDGE) AND TO THE BOTTOM CHORD OF THE STATIC

TRUSS (I-95 PISCATAQUA RIVER BRIDGE). HORIZONTAL CLEARANCES ARE BETWEEN BRIDGE PIERS CENTERED

AT THE CHANNEL'S CENTERLINE.

17. BORINGS AND PROBES SHOWN IN "INSET A" (THIS SHEET) WERE PREVIOUSLY PERFORMED BY OSI IN 2007

(BORINGS B1 THROUGH B6, AND PROBES P1, P2, AND P3); GZA IN 2016 (BORINGS FD16-01 THROUGH FD16-10);

AND LOUIS BERGER IN 2018 (BORINGS S-01 THROUGH S-17). REFER TO SECTION 00 32 00 GEOTECHNICAL DATA

FOR ADDITIONAL INFORMATION.

18. ATLANTIC TERMINALS T14A IS LOCATED AT THE SPRAGUE TERMINAL (372 SHATTUCK WAY, NEWINGTON, NH), APPROXIMATELY 3.7 MILES NORTH OF ROUTE 95, EXIT 4 OFF OF ROUTE 4, SPALDING TURNPIKE NORTH, TRAVEL

1,712 FEET FROM SHATTUCK WAY MAIN GATE, APPROXIMATELY 196 FEET ALONG THE DOCK, FROM THE EDGE

OF THE SERVICE ROAD, AND 137 FEET SE OF THE SE CORNER OF A BUILDING ON THE BANKS OF THE

PISCATAQUA RIVER NEAR THE BOAT PIER.
