About this file

Written by GovTribe AI · May 9, 2025

These are engineering design drawings for a comprehensive waterfront repair project at the U.S. Coast Guard Academy in New London, Connecticut. The 22-page technical document contains detailed structural plans and specifications for repairing multiple waterfront facilities, including the T-Boat Pier, Railroad Overpass Bridge, multiple floating docks, Main Pier, Bulkhead, and Crew Pier. The project involves extensive repairs such as replacing timber piles, decking, and curbing, cleaning and recoating steel structures, repairing concrete spalls, replacing guide pile assemblies, and demolishing and replacing damaged infrastructure. The drawings, prepared by Appledore Marine Engineering, LLC, provide precise technical details including material specifications, replacement schedules, environmental considerations, and specific repair methodologies for each facility, with a focus on marine construction techniques and preservation of existing structural elements.

2. AN ENVIRONMENTAL PROTECTION PLAN MUST BE PREPARED PRIOR TO CONSTRUCTION WORK. THE PLAN MUST IDENTIFY CONSTRUCTION ELEMENTS AND RECOGNIZE SPILL SOURCES AT THE SITE. THE PLAN MUST OUTLINE BMPS, RESPONSIVE ACTIONS IN THE EVENT OF A SPILL OR RELEASE, AND NOTIFICATION AND

REPORTING PROCEDURES. IT MUST ALSO OUTLINE MANAGEMENT ELEMENTS SUCH AS PERSONNEL

RESPONSIBILITIES, PROJECT SITE SECURITY, SITE INSPECTIONS, AND TRAINING.

3. COMPLY WITH FEDERAL, STATE, AND LOCAL REGULATIONS PERTAINING TO THE ENVIRONMENT, INCLUDING WATER, AIR, SOLID WASTE, HAZARDOUS WASTE AND SUBSTANCES, OILY SUBSTANCES, AND NOISE POLLUTION.

4. PROVIDE AND MAINTAIN ENVIRONMENTAL CONTROLS AS REQUIRED BY FEDERAL, STATE, AND LOCAL REGULATIONS AND PERMITS. ENVIRONMENTAL CONTROLS MUST INCLUDE BUT NOT BE LIMITED TO TURBIDITY

AND DUST.

5. CONSTRUCTION MEANS AND METHODS MUST PREVENT DEBRIS, DUST, OR EFFLUENTS CREATED BY THE

PROJECT FROM GETTING INTO THE AIR OR WATER.

6. PROVIDE EROSION AND SEDIMENT CONTROL MEASURES IN ACCORDANCE WITH STATE AND LOCAL LAWS AND

REGULATIONS.

LIMITS OF WORK

1. REMOVE AND PROTECT EXISTING TIMBER FENDER CHOCK TO ALLOW FOR

DRIVING OF FENDER PILE. REINSTALL TIMBER FENDER CHOCK UPON

COMPLETION OF FENDER PILE INSTALLATION.

2. CUT PILE, MINIMUM NECESSARY, TO FIT UNDER PILE CAP PRIOR TO PULLING INTO

PLACE AND RESTORE TYPICAL PILE TO PILE CAP CONNECTION, SEE DETAIL

A5/S-501A.

3. DO NOT CUT TIMBER LOGS, STRINGERS, DECK, OR CURB TO INSTALL PILES. IF

REQUIRED, THESE ELEMENTS CAN BE TEMPORARILY MOVED DURING PILE

INSTALLATION. UPON COMPLETION OF PILE INSTALLATION REINSTALL THESE

ELEMENTS. REFER TO DETAIL A7/S-501A FOR THE LOG AND STRINGER

CONNECTIONS TO THE PILE CAPS.

4. BRACING MUST BE INSTALLED AFTER PILE REPAIRS ARE COMPLETED.

5. TIMBER FENDER PILES MUST BE ENTIRELY EXTRACTED AND NOT CUT AT

MUDLINE.

6. DRIVE TIMBER FENDER PILES TO BEDROCK OR A MINIMUM 20 FT EMBEDMENT.

7. THE MUDLINE ELEVATION VARIES BETWEEN -10.1FT AND -12.2FT MLLW. PROVIDE

SUFFICIENT PILE LENGTHS TO ENSURE MINIMUM EMBEDMENT DEPTHS ARE

OBTAINED.

8. FOR BIDDING PURPOSES, ASSUME 45 FT LONG BEARING AND FENDER PILES.
