Encls As Stated

Maint Drdg Wilmington Harbor Outer Ocean Bar W912PM-16-B-0009 Brunswick County, North Carolina the Contracting Officer or his/her designated representative.

1.12.4 Method of Survey

Hydrographic surveys will be accomplished by the Government to determine the volume of material removed under this contract. The surveys will be accomplished with the use of an automated survey system installed aboard one of the Wilmington District's survey vessels. Vertical datum for all hydrographic surveys will be mean lower low water.

****Amendment 0001****

1.12.4.1 Singlebeam Surveying Method

The singlebeam survey system will be used. Horizontal location of survey lines and depth sounding points will be determined by the use of an automated positioning system utilizing RTK GPS (real time kinematic global positioning system). Depth soundings will be taken using a dual frequency (200/28 KHz) depth sounder. The fathometer will be calibrated using velocity casts to account for variations of the speed of sound in the water at the survey site and compared to periodic bar checks for consistency.

Payment for material removed from Baldhead Shoal Channel Reach 3 will be based on 28 kHz depth soundings. Payment for material removed from Southport Channel and Battery Island Channel will be based on 200 kHz depth soundings. The echo sounder system will be calibrated at the job site and verified for accuracy twice daily.

****Amendment 0001****

1.12.4.2 Survey Lines

Depth soundings will be secured by running survey lines parallel to the longitudinal axis of the channel. A sufficient number of lines will be run to assure good coverage of the bottom. Cross check lines will be run at 500' intervals. A minimum of two (2) lines will be run within the grade slopes. The after dredging survey will be performed in the same manner as the before dredging survey.

1.13 TIDE DATA

1.13.1 Real Time Kinematic (RTK) GPS

Real Time Kinematic (RTK) GPS will be used by the Corps of Engineers to determine real time water levels (tide corrections) in the Wilmington Harbor Project area. If the Contractor desires to obtain these corrections, he/she shall be responsible for providing navigation equipment capable of utilizing the transmitted signals from North Carolina Geodetic Surveys Continuously Operating Reference Station Network. Contact Mr. Bart Alligood (System Administrator) for access at 919-948-7834.

1.13.2 Kinematic Tidal Datum

A file listing the separations between the Reference Ellipsoid and the Chart Datum (Mean Lower Low Water for Wilmington Harbor) will be provided to the Contractor for entry into the hydrographic survey software. A Tidal Datum Diagram showing the relationship between NAVD 88 and Mean Lower Low Water for Wilmington Harbor will be provided upon request.

SECTION 35 20 23 Page 7 (Revised by Amendment 0001)

1.13.3 RTK GPS Disputes

Any discussions or dispute regarding the validity and use of this method of surveying and determining of real time tides must be resolved prior to the commencement of dredging on this project.

1.14 PLANT

Dredging shall be performed by ocean certified hopper dredge. See Section 01 10 00.10 38 paragraph PLANT for additional requirements for the plant to be used on the project.

PART 2 PRODUCTS

Not used.

PART 3 EXECUTION

3.1 DREDGE POSITIONING SYSTEM

Each dredge shall be equipped with an electronic positioning system, capable of positioning the dredge in the channel with accuracies as shown in Table 3.1 Minimum Performance Standards for Corps of Engineers Hydrographic Surveys (Mandatory) in USACE EM 1110-2-1003. This positioning system shall be established, operated, and maintained by the Contractor during the entire period of the contract. The positioning system shall be used to precisely locate the dredge and dragarm, and shall be capable of displaying and recording the dredge's location in an acceptable coordinate system which can be related to, or is directly based on, the North Carolina Lambert State Plane Coordinate System (NAD 1983, State Plane feet).

Navigation channel control, and shore station control, if required, will be provided to the Contractor in the same North Carolina Coordinate System prior to the commencement of work. It shall be the responsibility of the Contractor to have the positioning/navigation system reviewed, inspected and approved by the Contacting Officer or his/her designated representative prior to the commencement of work.

3.2 QUANTITIES SUMMARY

The quantities listed in Attachment 1 - Quantities Summary include the volumes present at the time of the surveys indicated in the contract drawings plus shoaling anticipated before dredging begins.

Should the total quantity of material to be paid for under the contract exceed the limit established in the clause entitled "VARIATIONS IN ESTIMATED QUANTITIES - DREDGING", additional time will be allowed at the rate of one (1) calendar day for the average daily production rate achieved by the equipment used on the project for excavation in excess of the established limit.

3.3 DISPOSAL OF DREDGED MATERIAL

The Government furnished disposal area available to the Contractor for disposal of dredged material is the Ocean Dredged Material Disposal Site

(ODMDS).

3.3.1 Wilmington Harbor Ocean Dredged Material Disposal Site (ODMDS)

Disposal of dredged material from the Wilmington Harbor channels shall be

SECTION 35 20 23 Page 8 in the Ocean Dredged Material Disposal Site (ODMDS) within the designated disposal zone shown on the drawings. Disposal shall be conducted in such a manner that water above the dumped material will have a minimum clearance of 30 feet at mean lower low water (MLLW). In order to maximize ODMDS capacity and minimize mounding of material, the dumps shall be scattered throughout the designated disposal zone and not placed repeatedly at one location. This shall be accomplished by dividing the disposal zone into quadrants and placing successive dump loads into successive quadrants.

3.4 DREDGED MATERIAL DISPOSAL PLAN

Prior to commencement of dredging and disposal operations, the Contractor shall submit to the Contracting Officer or his/her designated representative a disposal plan for dredged material. The plan shall include but not be limited to the following:

a. procedures for maximizing the ODMDS disposal zone capacity and minimizing mounding of material (reference subparagraph Wilmington Harbor Ocean Dredged Material Disposal Site (ODMDS))and anticipated disposal volume.

b. procedures for recording verification of ocean disposal in the ODMDS disposal zone and ensuring minimum clearance is provided (see paragraph DREDGE POSITIONING SYSTEM and Section 35 20 23.23 NATIONAL

DREDGING QUALITY MANAGEMENT PROGRAM HOPPER DREDGE).

c. anticipated cycle times and disposal vessel route to and from the ODMDS (reference paragraph REQUIRED TRANSPORTATION ROUTE).

3.5 EMERGENCY DUMPS

If a vessel experiences an emergency situation which causes a dumping of material outside of the designated disposal zone, the Contractor shall verbally notify the Contracting Officer or his/her designated representative no later than the next work day. The Contractor shall submit, in writing within two (2) days of the emergency dump, a statement detailing time of dump, location of dump, and reason dump occurred.

Material that is misplaced due to an emergency dump situation is subject to removal by the Contractor at his own expense upon the request of the Contracting Officer or his/her designated representative.

3.6 REQUIRED TRANSPORTATION ROUTE

For surface vessel transportation of dredged material to the Ocean Dredged Material Disposal Site (ODMDS) disposal zone, the vessel(s) shall travel in the buoyed navigation channel until they are seaward of Buoy "2". These vessels shall return to the site of work by the same route.

3.7 DEBRIS SCREENING

The Contractor may encounter wood and other debris within the dredging limits. The wooden debris may consist of tree trunks, stumps, roots, and limbs. The size of the wood may vary considerably. All wood debris material captured on or in the hopper dredge dragheads shall be removed and placed in a separate barge or other conveyance and disposed of in a public or private upland disposal area in accordance with all applicable Federal, State, and local laws and regulations. Bidders are expected to investigate the availability of disposal areas and any restrictions associated with each prior to submitting their bids.

SECTION 35 20 23 Page 9

3.8 FENDER TIRES

All fender tires used on Contractor dredging equipment or vessels shall be permanently marked by the Contractor with the company name and equipment plant name.
