The authorized project provides for the deepening and strategic widening of the Federal navigation channel from the entrance of Bar Cut-3 through station 28+18.43 of Cut-45 to a project depth of 47 feet plus applicable overdepths and Advance Maintenance. The completion of the work will take place under multiple contracts. Contract B will dredge from Cut-7 Station 10+00 to Cut-42 Station 33+80 to a required depth of 48 feet plus 1 foot allowable overdepth. In addition, Advance Maintenance Areas 2 and 3 incorporate an additional 2 feet of required dredging where applicable.

Total quantity to be dredged from the Federal Channel is approximately 5.7 million cubic yards (cy). All dredged material will be placed in the approved Ocean Dredged Material Disposal Site (ODMDS) which is located an average of 13.4 nautical miles from the dredging location. Materials to be dredged consist of unconsolidated materials consisting of sand and silty sand, occasional silt, stiff clay and shell layers, and rock varying from poorly indurated and weathered to hard. Work is divided into a base and one option as indicated in Section 00010A LINE ITEMS AND PRICING SCHEDULE.

1.2.2 Location

1.6 LAYOUT OF WORK

Read this paragraph in conjunction with the Clause LAYOUT OF WORK (FAR 52.236-17) of Section 00700 CONTRACT CLAUSES in Volume 1.

1.6.1 Established Project Control

The Government has established monuments along the work site(s). Each monument is represented in the contract drawings by a Designation and in most cases, an alphanumeric Permanent Identifier (PID). Information concerning the location and elevations can be found within the Survey Notes on the plan sheets. The Survey Notes for each included field survey will cite a particular survey number, and specify the control used to conduct that survey. Additional information is included in the Survey Notes that must be duplicated if an attempt to recreate the subject survey is desired.

For navigation channels, the Government has established tidal calibration sites for projects constructed and maintained to a tidal datum. Each tidal calibration site is represented in the plan sheet drawings by Station ID, and is cited in the Survey Notes. All projects constructed and maintained to a tidal datum shall be calibrated to the Station ID specified in the plan sheet drawings. Information regarding the location and associated benchmarks of the referenced Station ID is included in the Monument Description section of these specifications.

See Section 00 31 21 CONTROL MONUMENT DESCRIPTIONS.

1.6.2 Layout

From the monuments, control data and elevations established by the Government, the Contractor shall complete the layout of the work and shall be responsible for all measurements that may be required for the execution of the work to the location and limit marks prescribed in the specifications or on the contract drawings, subject to such modifications as the Contracting Officer may require to meet changed conditions or as a result of necessary modifications to the contract work.

1.6.3 Survey

The Contractor shall furnish, at his own expense, such stakes, templates, platforms, equipment, tools and material, and all labor as may be required in laying out any part of the work from the monuments, control data and elevations established by the Government. It shall be the responsibility of the Contractor to maintain and preserve all stakes and other marks established by the Contracting Officer until authorized to remove them, and if such marks are destroyed by the Contractor or through his negligence, prior to their authorized removal, they may be replaced by the Contracting Officer, at his discretion, and the expense of replacement will be deducted from any amounts due or to become due the Contractor. The Contracting Officer may require that work be suspended at any time when location and limit marks established by the Contractor are not reasonably adequate to permit checking of the work.

The Jacksonville Harbor Targets and Dive Results are posted in a PDF file. The map of magnetic anomalies and sidescan locations is posted as a Google Earth KMZ file.

3.4 DISPOSAL OF EXCAVATED MATERIAL

3.4.1 Ocean Dredged Material Disposal Site (ODMDS)

The material excavated shall be transported to and deposited in the ODMDS shown on the drawings. The average distance to which the material will have to be transported to the ocean disposal area will be approximately

13.4 nautical miles and the maximum distance will be approximately 17.6 nautical miles. Dredged material shall not be placed higher than elevation -30 feet MLLW in Jacksonville ODMDS. Transport distances vary depending upon location of dredging reaches relative to the designated ODMDS Release Zones for each reach which are as follows:

DREDGING REACH RELEASE ZONE

Station 10+00 Cut-7 through Station 19+11.22 Cut-13 (Range -212.50 through

Range -412.50) B1

All other areas C1

Disposal shall be initiated when the vessel is completely within the designated disposal release zone as shown on the drawings, and the disposal vessel shall not leave the ODMDS boundary until the release doors or split-hull sections are fully closed.

3.4.2 Spillage/Leakage

Water and excavated material shall not be permitted to overflow, leak out, or spill out of the barges, dump scows, or hopper dredges while in transit to the ODMDS release zones. Transit to the ODMDS begins as soon as dredged material loading into the disposal vessel is completed and the vessel begins moving to the ODMDS. Failure to repair leaks or change the method of operation which is resulting in the overflow, leakage, or spillage will result in suspension of dredging operations and require prompt repair or change of operation to prevent overflow, leakage, or spillage as a prerequisite to the resumption of dredging. Appropriate measures may include, but are not limited to, up-to-date U.S. Coast Guard and/or American Bureau of Shipping certification of all disposal-related vessels, maintenance (inspection and/or replacement) of gaskets on barge doors, minimization of excess free liquids in barge loads, pre-transit testing of barge door hydraulics, and pre-transport verification of appropriate weather and sea state conditions. The Contracting Officer shall be notified within 24 hours if any apparent leaking or spilling of dredged material occurs as indicated by an average loss of draft during transit from the dredging area to the disposal release zones (forward draft loss plus aft draft loss divided by 2) in excess of 2.0 feet. Excessive leakage may be classified as a mis-dump and pay deducted for the entire load.

SECTION 35 20 23 Page 10

3.4.3 Mis-Dump

Any scow load or hopper dredge load that is released outside the boundaries of the release zone as shown on the drawings will be classified as a mis-dump and will result in a suspension of dredging operations. Mis-dump material will be treated in accordance with the provisions of the subparagraph "Misplaced Material" below.

3.4.4 Vessel Doors

All hopper doors, dump scow doors, or split hull dumping mechanisms shall be closed and sealed prior to exiting the ODMDS as documented by the hull sensors. In the event that a dump vessel exits the ODMDS with open doors, then the Contractor shall notify the Contracting Officer immediately of the occurrence. Corrective actions shall be implemented by the next dump and the Contracting Officer shall be informed of actions taken.

3.4.5 Electronic Tracking System (ETS) for Ocean Disposal Vessels

The Contractor shall furnish an ETS for surveillance of the movement and disposition of dredged material during excavation and ocean disposal. This ETS shall be established, operated and maintained by the Contractor to continuously track in real-time the horizontal location and draft condition of the disposal vessel for the entire dredging cycle, including dredging area and disposal area. The ETS shall be capable of displaying and recording in real-time the disposal vessel's draft and location.

3.4.5.1 ETS Standards

The Contractor shall provide automated (computer) system and components to perform in accordance with EM 1110-1-2909 . A copy of the EM can be downloaded from the following web site:

http://www.publications.usace.army.mil/USACEPublications/EngineerManuals.aspx.

Horizontal location shall have an accuracy equal to or better than a standard DGPS system, equal to or better than plus/minus 10 feet (horizontal repeatability). Vertical (draft) data shall have an accuracy of plus/minus 0.1 foot. Horizontal location and vertical data shall be collected in sets and each data set shall be referenced in real-time to date and local time (to nearest minute), and shall be referenced to the same state plane coordinate system used for the survey(s) shown in the contract plans. The ETS shall be calibrated, as required, in the presence of the Contracting Officer at the work location before disposal operations have started, and at 30-day intervals while work is in progress. The Contracting Officer shall have access to the ETS in order to observe its operation. Disposal operations will not commence until the ETS to be used by the Contractor is certified by the Contracting Officer to be operational and within acceptable accuracy. It is the Contractor's responsibility to select a system that will operate properly at the work location. The complete system shall be subject to the Contracting Officer's approval.

3.4.5.2 ETS Data Requirements and Submissions

a. The ETS for each disposal vessel shall be in operation for all dredging and disposal activities and shall record the full round trip for each loading and disposal cycle. (NOTE: A dredging and disposal cycle constitutes the time from commencement of dredging to complete discharge of the material.) The Contracting Officer shall be notified immediately in the event of ETS failure and all dredging operations for the vessel shall cease until the ETS is fully operational. Any delays

SECTION 35 20 23 Page 11 resulting from ETS failure shall be at the Contractor's expense.

b. All data shall be collected and stored on CD-ROM(s) in ASCII format and shall be readable by MS Windows compatible software. Each dredging and disposal cycle shall be a separate and distinct ASCII file, labeled by the trip number. More than one file may be stored on the disc(s) or CD-ROM(s).

c. Data shall be collected at least every 0.25 nautical mile or every 4 minutes during travel to and from the ODMDS and 12 seconds or every 30 feet of travel, while the hull status is open within the ODMDS.

d. The required digital data to be collected for each dredging and disposal cycle includes the following:

(1) Load Number

(2) Disposal Vessel Name and Type (e.g. scow)

(3) Estimated Volume of Load

(4) Description of Material Disposed

(5) Source of Dredged Material

(6) Date, Time and Location at Initiation and Completion of

Disposal Event in accordance with subparagraph c. above

(7) Vessel Draft

e. Plot Reporting (2 types):

(1) Tracking Plot - For each disposal event, all data collected while the disposal vessel is transiting to and from the disposal area shall be plotted in chart form, in 200-foot intervals, to show the track and draft of the disposal vessel approaching and traversing the disposal area. The plot shall identify the exact position at which the dump commenced. A sample Track and Draft Plot Diagram is on the web site indicated in paragraph CONSTRUCTION FORMS AND DETAILS below.

(2) Scatter Plot - Following completion of all disposal events, a single and separate plot will be prepared to show the exact disposal locations of all dumps. Every plotted location shall coincide with the beginning of the respective dump. Each dump shall be labeled with the corresponding Trip Number and shall be at a small but readable scale. A sample Scatter Plot Diagram is on the web site indicated in paragraph CONSTRUCTION FORMS AND DETAILS below.

(3) Summary Table - A spreadsheet which contains all of the information described in subparagraph d. above shall be prepared and shall correspond to the exact dump locations represented on the Scatter Plot Diagram. A sample Summary Table spreadsheet is on the web site indicated in paragraph CONSTRUCTION FORMS AND DETAILS below.

f. All digital ETS data shall be furnished to the Contracting Officer within 24 hours of collection (see " Electronic Tracking System Data " of paragraph SUBMITTALS above). The digital plot files should be in an easily readable format such as Adobe Acrobat PDF file, Microstation DGN file, JPEG, BMP, TIFF, or similar. The hard copy of the ETS data and tracking plots shall be both maintained onboard the vessel and submitted to the Contracting Officer on a weekly basis.

3.4.6 Dredge Pipelines

3.4.6.1 Dredge Discharge Pipeline

The Contractor shall plainly mark the pipeline access routes with conspicuous stakes, targets and/or buoys to be maintained throughout the contract operations. A tight dredge discharge pipeline shall be maintained to prevent spilling of dredged material or dredge water outside of the disposal area. The Contractor shall provide and maintain radio communication between the dredge and the disposal areas and the dredge and the Contracting Officer. The pipeline shall be inspected at least twice daily for leaks. Failure to immediately repair leaks in the discharge pipeline will result in suspension of dredging operations and require prompt repair of pipeline as a prerequisite to the resumption of dredging.

Any damage to private or public property resulting from the Contractor's operations shall be repaired by the Contractor at his expense.

3.4.6.2 Submerged Pipeline

In the event the Contractor elects to submerge his pipeline, the pipeline shall rest on the bottom, and the top of the submerged pipeline and any anchor securing the submerged pipeline shall be no higher than the required project depth for the channel in which the submerged pipeline is placed.

Should the Contractor elect to use a pipeline material which is buoyant or semi-buoyant, such as PVC pipe or similar low density materials, the Contractor shall securely anchor the pipeline to prevent the pipeline from lifting off the bottom under any conditions. The Contractor shall make daily inspections of the submerged pipeline to ensure buoyancy has not loosened the anchors. The Contractor shall remove all anchors when the submerged pipeline is removed. The location of the entire length of submerged pipeline shall be marked with signs, buoys, lights, and flags conforming to U.S. Coast Guard regulations.

3.4.6.3 Floating Pipeline

Should the Contractor's pipeline not rest on the bottom, it will be considered a floating pipeline and shall be visible on the surface and clearly marked. In no case will the Contractor's pipeline be allowed to fluctuate between the surface and the bottom, or lie partly submerged.

Lights shall be installed on the floating pipeline as required in paragraph SIGNAL LIGHTS above. The lights shall be supported either by buoys or by temporary piling, provided by the Contractor and approved by the Contracting Officer. Where the pipeline does not cross a navigable channel, the flashing yellow all-around lights shall be spaced not over 200 feet apart, unless closer spacing is required by U.S. Coast Guard personnel, in which case the requirements of the U.S. Coast Guard shall govern, at no additional cost to the Government.

3.4.7 Booster Pumps

Any booster pumps installed by the Contractor shall be located at least 300 feet from any residential-type building or house. Booster pumps, their prime movers, and any auxiliary equipment shall be fitted or equipped with mufflers, noise control enclosures, or other engineering noise control methods, measures, and features such that steady noise emanating from this equipment does not exceed 85 decibels on the A scale at slow response, and impulsive noise does not exceed 140 decibels. Such items shall be maintained throughout the course of the work.

SECTION 35 20 23 Page 13

3.4.8 Misplaced Material

Materials deposited outside of the ODMDS disposal area(s) will be classified as misplaced material and will result in a suspension of dredging operations. Redredging of such materials will be required as a prerequisite to the resumption of dredging unless the Contracting Officer, at his discretion, determines that redredging of such material is not practical. If redredging of such material is not required then the quantity of such misplaced material shall be deducted from the Contractor's pay quantity. If the quantity for each misplaced load to be deducted cannot initially be agreed to by both the Contractor and Contracting Officer, then an average hopper/scow load quantity for the entire contract will be used in the determination. Materials deposited above the maximum indicated elevation of the disposal area will require the degrading or removal of such materials at the Contractor's expense. In addition, the Contractor shall notify the Contracting Officer and the Environmental Protection Agency within 24 hours of a misplaced dump or any other violation of the Site Monitoring and Management Plan for Jacksonville ODMDS. Corrective actions shall be implemented by the next dump and the Contracting Officer must be informed of actions taken.

3.5 REQUIRED DEPTH, ALLOWABLE OVERDEPTH, AND SIDE SLOPES

3.5.1 Required Depth

The material actually removed from the designated areas to be dredged, to a depth of not more than the required depth shown on the drawings, will be estimated and paid for in accordance with the provisions contained in the subparagraphs "Measurement" and "Payment" of Section 01 22 00 MEASUREMENT

AND PAYMENT.

3.5.2 Allowable Overdepth

To cover the inaccuracies of the dredging process, material actually removed from the designated areas to be dredged, to a depth below the required depth of not more than the allowable overdepth shown on the drawings, will be measured and paid for in accordance with the provisions contained in the subparagraphs "Measurement" and "Payment" of Section

01 22 00 MEASUREMENT AND PAYMENT.

3.5.3 Side Slopes

Although dredging of side slope material may be necessary to provide the required project channel dimensions (depth and width), the side slopes shown on the drawings are provided for payment purposes only. Side slopes may be formed by box cutting, step cutting, or dredging along the side slope. Material actually removed, within the limits approved by the Contracting Officer, to provide for final side slopes not flatter than that shown on the contract drawings, but not in excess of the amount originally lying above this limiting side slope, will be measured and paid for in accordance with the provisions contained in subparagraphs "Measurement" and "Payment" of…
