This document is a set of civil engineering design drawings and specifications for the U.S. Coast Guard Station Portsmouth Harbor in New Castle, New Hampshire, addressing waterfront repair and restoration work identified as Phase 2.

The project encompasses four primary repair areas: (1) bulkheads and quay walls requiring chinking, repointing, void repair, and concrete closure walls at the north and south locations; (2) rip-rap revetment restoration involving stone placement, bedding layers, and geotextile installation across approximately 380 cubic yards; (3) wave screen/floating dock repairs including pile recoating with coal-tar epoxy, cleat replacement, and galvanic anode installation; and (4) a new timber floating dock replacement with expanded polystyrene float modules designed for 40 PSF uniform live load and 8-inch minimum freeboard. The base bid scope totals approximately 14 individual line items with quantities ranging from 8 each (pile coatings and anodes) to 700 cubic yards (interim stone berm). Two bid options are available: Option 1 provides 150 cubic yards of additional revetment extension at the west end of the quay wall (RPUID 816511), and Option 2 offers installation of eight HDPE pile sleeves for protection (RPUID 50109). Work restrictions limit loading within 15 feet of the existing north quay wall to 100 PSF uniform live load, with vehicles and cranes prohibited. The project specifications reference 2018 International Building Code, AISC Steel Construction Manual 15th Edition, 2024 American Wood Council NDS, Unified Facilities Criteria 4-152-01 and 4-152-07, and OSHA 29 CFR 1910. Design by Lloyd-Collins JV (Bellaire, Texas) and USCG Civil Engineering Unit Providence; drawings issued for bidding November 2025.

DOCKS SHALL HAVE A MINIMUM FREEBOARD OF 18-22 INCHES UNDER DEAD LOAD CONDITIONS, INCLUDING ALL PERMANENT DOCK COMPONENTS AND GANGWAY. DOCKS SHALL NOT HAVE MORE THAN A 5 DEGREE LIST AFTER

COMPLETED INSTALLATION.

3. ADDITIONAL FLOATATION SHALL BE USED FOR FLOATING DOCK UNDER GANGWAY LANDING TO PROVIDE LEVEL FLOATATION UNDER

GANGWAY DEAD LOAD.

4. FLOATING DOCK WILL BE EXPOSED TO WIND AND WAVES DURING ERECTION AND WHILE IN SERVICE, AND CONTRACTOR SHALL ANALYZE, DESIGN AND CONSTRUCT ACCORDINGLY. CONTRACTOR SHALL PROVIDE BRACKETED CONNECTIONS AND HARDWARE TO ACCOMMODATE DESIGN LOADS AND FREEBOARD REQUIREMENTS AS OUTLINED ABOVE, AND TO WITHSTAND ENVIRONMENTAL WAVE AND VESSEL WAKE ACTION NORMAL TO THE SITE. THE FOLLOWING IS MINIMUM DESIGN CRITERIA THAT SHALL BE USED FOR THE DOCK SYSTEM:

4.a. UNIFORM LIVE LOAD: 40 PSF 4.b. CURRENT VELOCITY: 0.5 FPS 4.c. SIGNIFICANT WAVE HEIGHT (HS): 2.0 FT 4.d. WAVE PERIOD: 3 SECONDS 4.e. VESSEL IMPACT: 1000 FT-LB AT 10 DEGREES FROM LONGITUDINAL AXIS 4.f. WIND LOAD: 22 PSF ON MOORED VESSEL PROFILES AND EXPOSED FLOAT AREAS.

4.g. MOORED VESSEL: (2) 47-FT MOTOR-LIFE BOAT, ONE LOCATED ON EACH SIDE OF DOCK.

5. PILE GUIDE ASSEMBLIES SHALL BE ROLLER-TYPE, CONSTRUCTED OF HDG HOLLOW STRUCTURAL STEEL OR HDG STEEL ANGLES WITH A

MINIMUM STEEL THICKNESS OF 3/8-INCH.

6. CLEATS SHALL BE 15-INCH HOT-DIPPED GALVANIZED CAST STEEL AND INSTALLED IN ACCORDANCE WITH THE MANUFACTURER'S RECOMMENDATIONS, USING THRU-BOLTED CONNECTIONS. MOORING HARDWARE AND MOORING HARDWARE CONNECTIONS SHALL BE

DESIGNED FOR A 3,500 LB LINE LOAD.

7. REFER TO SPECIFICATION SECTION 35 51 13.00 FOR ADDITIONAL REQUIREMENTS.WORK RESTRICTIONS:

1. THE CONTRACTOR IS ADVISED THAT LOADING WITHIN 15 FEET OF THE EXISTING NORTH QUAY WALL FACE IS LIMITED TO 100 PSF UNIFORM

LIVE LOAD. VEHICLES, CRANES, OR OTHER LOAD HANDLING EQUIPMENT IS PROHIBITED IN THIS AREA. REFER TO SEE SHEET G-101 AND THE

1. REFERENCE: USCG STATION PORTSMOUTH HARBOR NEWCASTLE, NH

2. FIELD SURVEY PERFORMED BY J.H.H. & S.N.F. (SURVEYING AND MAPPING, LLC) DURING

MARCH, 2025 USING A TOTAL STATION AND A SURVEY GRADE GPS WITH A DATA

COLLECTOR AND A DIGITAL LEVEL. TRAVERSE ADJUSTMENT BASED ON LEAST SQUARE

ANALYSIS.

3. TERRESTRIAL LIDAR SURVEY PERFORMED BY M.J.C. (SURVEYING AND MAPPING, LLC) ON

MARCH 10, 2025 USING A LEICA HDS SCANNER. REGISTRATION ADJUSTMENT BASED ON

LEAST SQUARE ANALYSIS.

4. HORIZONTAL DATUM BASED ON NAD83(2011) NEW HAMPSHIRE STATE PLANE COORDINATE

ZONE (2800) DERIVED FROM REDUNDANT GPS OBSERVATIONS UTILIZING THE KEYNET GPS

VRS NETWORK.

5. VERTICAL DATUM IS BASED ON NAVD88 PER DIFFERENTIAL LEVELS FROM DISK

CONSTITUTION 147 RM 1 (PUBLISHED NAVD88 ELEVATION = 14.69'). THIS DISK WAS ALSO

USED AS CONTROL POINT #3 SHOWN HEREON.

6. HIGHEST OBSERVABLE TIDE LINE IDENTIFIED BY LUKE HURLEY, CWS#232 ON MARCH 1,

2025.

7. PROPER FIELD PROCEDURES WERE FOLLOWED IN ORDER TO GENERATE CONTOURS AT 1'

INTERVALS. ANY MODIFICATION OF THIS INTERVAL WILL DIMINISH THE INTEGRITY OF THE

DATA, AND DOUCET SURVEY WILL NOT BE RESPONSIBLE FOR ANY SUCH ALTERATION

PERFORMED BY THE USER.

8. THE ACCURACY OF MEASURED UTILITY INVERTS AND PIPE SIZES/TYPES IS SUBJECT TO

NUMEROUS FIELD CONDITIONS, INCLUDING; THE ABILITY TO MAKE VISUAL OBSERVATIONS,

DIRECT ACCESS TO THE VARIOUS ELEMENTS, MANHOLE CONFIGURATION, ETC.

9. UNDERGROUND UTILITIES SHOWN HEREON ARE THE RESULT OF A QUALITY LEVEL B

UTILITY DESIGNATION COMPLETED BY DOUCET SURVEY DURING MARCH 2025 AND FROM

DATA OBTAINED FROM RECORD MAPS & DRAWINGS. DOUCET'S UTILITY DESIGNATION WAS

COMPLETED IN ACCORDANCE WITH THE STANDARD PROCEDURES SET FORTH IN ASCE

38-22 AND CONSISTENT WITH APPROPRIATE QUALITY LEVELS. DRAIN & SANITARY SEWER

WERE VISUALLY ALIGNED AND MAPPED AT QUALITY LEVEL C UNLESS OTHERWISE SHOWN.

ALL ABOVEGROUND STRUCTURES, SURFACE FEATURES AND THE LOCATION OF THE MARK

OUT ARE THE RESULT OF AN INSTRUMENT SURVEY COMPLETED BY DOUCET UNLESS

OTHERWISE NOTED. THERE MAY BE OTHER UNDERGROUND UTILITIES, THE EXISTENCE OF

WHICH ARE NOT KNOWN OR CERTIFIED BY THE UNDERSIGNED. DIG-SAFE AND THE

APPROPRIATE AUTHORITIES MUST BE NOTIFIED PRIOR TO CONDUCTING TEST BORINGS,

EXCAVATION OR CONSTRUCTION ACTIVITIES.

10. QUALITY LEVEL D (QLD) RECORD UTILITY INFORMATION IS BASED ON USCG BASE PLAN

DRAWING P1805UPOR AND UTILITY RECORDS MADE AVAILABLE BY COLLINS ENGINEERS,

INC.. THE UTILITY INFORMATION IS ONLY INTENDED TO BE USED TO HELP FACILITATE A

GRAPHIC REPRESENTATION AND DO NOT REPRESENT SURVEY LOCATIONS.

NOTES

1. THE INTENT OF THE BEDDING LAYER AND RIPRAP SLOPE SHOWN IS TO IMPROVE PROTECTION AND STABILIZATION OF THE ERODED SHORELINE AREA, LOCATED ABOVE MEAN HIGH WATER. THE EXISTING SLOPE IN THIS AREA SHALL BE EXCAVATED AND PREPARED TO SET THE TOE STONES, BEDDING LAYER, AND RESTORED SLOPE PROTECTION AS SHOWN ON THE DRAWINGS. IN THE EVENT THAT LEDGE OUTCROPPINGS ARE PRESENT THAT INTERFERE WITH THE PROPOSED BEDDING AND RIPRAP LAYERS SHOWN, THE BEDDING LAYER THICKNESS MAY BE REDUCED, OR TERMINATED IN THE AREA OF INTERFERENCES, TO FACILITATE CONSTRUCTION AND MAINTAIN A CONSISTENT REVETMENT FACE. IF THE BEDDING LAYER IS TERMINATED AT THESE AREAS, THE GEOTEXTILE LAYERS FOR THE SURROUNDING BEDDING SHALL BE TURNED BACK A MINIMUM 18 INCHES TO PREVENT LOSS OF BEDDING MATERIAL.

2. THE EXISTING ELECTRICAL AND TELECOMMUNICATION UTILITIES LOCATED WITHIN THE LIMITS OF WORK SHALL BE TEMPORARILY SUPPORTED AND PROTECTED DURING THE WORK, OR REMOVED, SALVAGED, AND REINSTALLED. UTILITIES THAT ARE DAMAGED AS A RESULT OF THE WORK SHALL BE REPLACED BY THE CONTRACTOR, AT NO ADDITIONAL COST TO THE GOVERNMENT.

3. EXISTING GRADE LINE IS SHOWN FOR REFERENCE. CONTRACTOR SHALL REMOVE EXISTING REVETMENT STONE, RUBBLE, VEGETATION, AND SOIL WITHIN THE LIMITS OF THE NEW REVETMENT AS NECESSARY TO COMPLETE THE WORK. EXISTING STONE MEETING THE GRADATION REQUIREMENTS MAY BE USED TO SUPPLEMENT THE NEW REVETMENT STONE. EXISTING STONES ALREADY ESTABLISHED IN THE INTENDED TOE STONE LOCATION, AND MEETING THE TOE STONE SIZE REQUIREMENTS, MAY REMAIN IN PLACE.

4. REMOVE EXISTING PAVEMENT AND EXISTING BASE COURSE IN THE LIMITS OF SINKHOLE REPAIRS TO A MINIMUM TOTAL DEPTH OF 10" BELOW TOP OF FINISH PAVEMENT.
