SUMMARY OF WORK

PART 1 GENERAL

1.1 NEW BEDFORD HURRICANE PROTECTION BARRIER BACKGROUND AND FEATURES

The New Bedford Hurricane Protection Barrier lies across New Bedford and Fairhaven Harbor. It is approximately 50 miles south of Boston. The project protects about 1,400 acres in New Bedford, Fairhaven, and Acushnet from tidal flooding associated with hurricanes and coastal storms. This acreage is thickly settled with industrial and commercial properties, particularly along the waterfront and the shores of the Acushnet River.

Construction of the New Bedford Hurricane Protection Barrier began in October 1962 and was completed in January 1966. The project required the relocation of power cables, modification of sewerage and drainage facilities, and acquisition of a small boat yard, several buildings, and about 36 acres of land. The city maintains the project, with the exception of the navigation gates and the barrier extending across New Bedford and Fairhaven Harbor which are operated and maintained by the Corps. The project is divided into three principal features: a barrier extending across New Bedford and Fairhaven Harbor with an extension dike on the mainland; Clarks Cove Dike in New Bedford; and Fairhaven Dike.

The barrier extending across the harbor consists of a 4,500-foot-long earthfill dike with stone slope protection.n The barrier has a maximum elevation of 20 feet and a 150-foot-wide gated opening to accommodate commercial and recreational navigation. It also has two gated conduits that are each nine feet high and six feet wide. The extension dike starts at the western end of the main dike and stretches for 4,600 feet along Rodney French Boulevard East. It has a maximum elevation of 22 feet. The extension dike has three circular gated conduits with diameters of two, three, and four feet, and a street gate on Rodney French Boulevard East.

Clarks Cove Dike consists of earthfill with stone slope protection. It is 5,800 feet long and extends around the north and east sides of the cove, tying to high ground at both ends. On the north side the dike has a maximum elevation of 22 feet, and on the east side the maximum elevation is 23 feet. The dike also has street gates at Rodney French Boulevard West and Cove Road, and a pumping station.

Fairhaven Dike consists of earthfill with stone slope protection. It starts at high ground near the foot of Lawton Street and runs easterly about 3,100 feet, with a maximum elevation of 20 feet. The dike also has a four-foot-diameter gated conduit.

1.2 WORK COVERED BY CONTRACT DOCUMENTS

The general description below is given to indicate the approximate scope of this project only. It does not limit the work required under the project drawings and specifications.

The work of this project consists of miscellaneous rehabilitation work on the navigation gates and appurtenances at the New Bedford/Fairhaven

SECTION 01 11 00 Page 3

Hurricane Barrier. Major work features include installation of stop gates and dewatering of navigation gate pockets, removal and disposal of PCB contaminated silt, sand, and debris from the base of the gates (an estimated 500 cubic yards of sediment in each gate pocket), jacking of the gates to allow gate wheel replacement with six new Government furnished wheels per gate leaf, replacement of three Government furnished wheel bushing housings, painting the entire steel surface of Horizontal Truss I on the sector gates, painting the exterior of the sector gates skin plate near the water line, spot painting of the sector gates and stop gate guide beams above the water line, lubrication of trunnion bearings, and repairing or replacing and checking of air jets and lubrication lines for the sector gate wheels. Repairs requiring underwater work include cleaning of stop gate wheel guides, removal of sediment, placement of jacks, and inspections. The gate pockets are considered a confined space, although no permit is required, and worker protection procedures shall be implemented by the Contractor. In addition, abrasive blasting of the sector gates will produce lead and cadmium products, and worker protection shall be implemented as specified for the painting work. The existing sector gate and appurtenances are painted with a zinc rich primer and coal tar epoxy system. By products from the steel manufacturing process may contain lead and cadmium and may be detected in the abrasive blasting debris. The gates and appurtances are not painted with lead paint.

SECTION 01 11 00 Page 14

Contracting Officer will inform the Contractor concerning Job Safety, Quality Control, Labor Relations, and Environmental Protection. The Contractor's Superintendent, Quality Control Representative, and Site Safety and Health Officer (SSHO) shall attend this conference.

1.16 AS-BUILT DRAWINGS

Maintain at the jobsite one set of paper full-size contract drawings marked to show all deviations that have been made from the contract drawings, including buried or concealed construction and utility features revealed during the course of construction. Record the horizontal and vertical location of all buried utilities that differ from the contract drawings.

These drawings shall be available for review by the Contracting Officer at all times. Upon completion of the work, submit the original marked set of prints to the Contracting Officer for approval. Also, provide PDFs of the current working redlines and/or markups complying with the as-built drawings and markup requirements. Requests for partial payments will not be approved if the marked prints and PDF files are not current, and request for final payment will not be approved until the marked prints and PDF files are submitted to and approved by the Contracting Officer.

1.16.1 Preparation of As-Built Drawings

The entries shall be made in the jobsite set of prints at the time field changes are made, pertinent information collected, or need for corrections established, as a continuing process during the life of the contract. As revised drawings are issued by the Contracting Officer, revised prints shall be introduced into the set to replace the superseded drawings and all applicable notations previously made on the superseded drawings transferred to the current prints. Carefully prepared sketches, not less than 8-1/2" x 11", may be used to depict changes or added information in lieu of notations on the actual prints. Staple sketches to the prints affected by the change. All plan views, sections, elevations, profiles, diagrams, details, or schedules affected by a change shall be marked up as required to reflect the change. All notations or changes made on the prints shall be in sufficient detail to clearly depict the change. Colored pens or pencils shall be used to make notations on the record prints as follows:

Red pen or pencil shall be employed to indicate added or corrected work or information.

Green pen or pencil shall be used to show the deleted or incorrectly depicted work or information.

Blue or black pen or pencil shall be used to show information not to be recorded on the drawings but included on the marked-up prints for explanatory or clarification purposes for the benefit of the Contracting Officer.

1.17 RECORD DRAWINGS

The record drawings are the final compilation of actual conditions reflected in the as-built drawings. The record drawings are CAD files produced from the source drawing files and marked-up as-built drawings.

The Contractor shall request the full set of electronic drawings, in the source CAD format, for Record Drawing preparation, after award and at least 30 days prior to required use. The Government will provide one set of "as-designed" electronic CAD files in AutoCAD Version 2019. The CAD files

SECTION 01 11 00 Page 15 are provided to enable preparation of record drawings. If discrepancies exist between the CAD files and the contract PDF drawings, correct the CAD files to show the contract PDF drawings. The Government has no responsibility to modify any GFM due to changes in the design that occur after award.

The Contractor shall prepare the CAD drawing files in AutoCAD Version 2019 or later format.

If additional drawings are required, prepare them using the specified electronic file format applying the same graphic standards specified for original drawings, ERDC/ITL TR-12-6 and ERDC/ITL TR-12-1. The title block and drawing border to be used for any new final record drawings must be identical to that used on the contract drawings.

If a sheet needs to be added between two sequential sheets, append a Supplemental Drawing Designator in accordance with ERDC/ITL TR-12-6, "Adding a Drawing Sheet", and ERDC/ITL TR-12-1, "Adding or Deleting Drawing Sheets and Index Sheet Procedures".

Provide electronic PDF files of all CAD contract drawings sheets associated with the record drawing submittal. Compile and organize the PDF set to match the contract drawings.

1.17.1 Final Record Drawing Annotation

When final revisions have been completed, show the wording "RECORD DRAWING AS-BUILTS" followed by the name of the Contractor in letters at least 3/16 inch high on the cover sheet drawing. Show the wording "RECORD DRAWING AS-BUILTS" in the revision block of each drawing.

1.17.2 Preparation and Submission of Record Drawings

Within 30 days after Government approval of all of the working as-built drawings, prepare the final CAD record drawings and submit CAD and PDF drawing files. Also submit all external references (x-refs), plot style files, and all other required CAD resource files. The Government will promptly return one set of prints annotated with any necessary corrections. Within 7 calendar days revise the CAD files accordingly at no additional cost and submit one set of final CAD files and PDF files to the Government. Drawing files and storage media submitted will become the property of the Government upon final approval. Failure to submit final record drawings as specified will be cause for withholding any payment due under this contract. Approval and acceptance of final record drawings must be accomplished before final payment is made.

1.17.3 Record Drawing Re-Submission Requirements

If elements of a record drawing submittal are rejected, provide the following for each re-submission, in addition to any information required in Section 01 33 00 SUBMITTAL PROCEDURES:

A. Re-submit all CAD components, including updated content in response to Government comments.

B. Provide a copy of all Government review comments.
