PART 2 PRODUCTS - NOT USED

PART 3 EXECUTION

3.1 MEASUREMENT AND PAYMENT

3.1.1 Mobilization and Demobilization, CLIN 0001

a. Measurement and payment for Mobilization and Demobilization will be considered complete and full compensation for the effort and cost to prepare the Contractor's plant and equipment for shipment; transport to and from the job site all necessary Contractor plant including related equipment, fuel, supplies, personnel required for its operation, and Government field office setup and on-board accommodations as stated in Section 35 20 23.00 82, DREDGING AND CHANNEL CLEARING, and Section

01 10 10.00 82, CONTRACTOR'S OPERATIONS AND REQUIREMENTS (DREDGING);

making ready for dredging; and maintaining plant and equipment in working condition at the site during the dredging period, and will be paid for at the Contract job price for this item. Plant subject to pre-work safety inspection requirements will not be considered "mobilized" until such equipment is determined to be in compliance as determined by the floating plant inspection and verified during the joint equipment walk-through.

3.1.2 Dredging of Materials; Bradford Island Fishladder Exit, CLIN 0002

a. Measurement and payment for the bid items referenced in the title above will be considered complete and full compensation for the effort and cost to excavate the entire dredging pay areas to not less than the "required dredging depth" as shown on the drawings, including water quality monitoring and placement of all dredged material within a suitable upland site in accordance with all applicable federal, state, 01 22 00.00 82-2 AMD #0002 and local lawsthat can accept hazardous material, and will be paid at the unit price (cubic yard of dredged material) for this item.

b. The Government will determine cubic yard quantities for payment by taking pre-dredge and post-dredge surveys utilizing electronic depth sounding and horizontal positioning equipment. See paragraph QUANTITY SURVEYS for measurement description.

3.2 PAYMENT METHOD

3.2.1 Pre/Post Dredge Survey

a. In Pre/Post Dredge Survey work areas, the Government will provide a required channel depth, with a maximum pay depth of one foot beyond the required channel depth, unless otherwise noted on the associated Contact drawings.

b. The dredging pay prism is formed by the maximum pay depth, and the horizontal dredging area limits. Request post-dredge Government hydrographic surveys in accordance with this Section. A work area will be accepted when all of the survey values inside the channel limits are equal to or deeper than the required channel depth.

3.2.2 Quantity Surveys

a. The Government will determine cubic yard quantities for payment and acceptance by utilizing electronic depth sounding and horizontal positioning equipment. Sounding depths used for determination of pay quantity volumes will generally be derived from surveys utilizing 208 kHz multi-beam acoustic methods. However, the Government reserves the right to take soundings by any method, including: leadline or trigonometric leveling (total station)/differential leveling. The same method will be used for the pre and post survey of a given reach.

b. The dredging pay area is defined by the intersection of the maximum dredging pay depth as shown by the Descriptive Sketch in Attachment [A]. The number of cubic yards calculated as being payable will be the difference between the most recent pre-dredge and post-dredge surveys of the dredging pay area or applicable acceptance area. Any material removed from outside the maximum dredging prism will not be considered for payment.

c. Accuracy(ies) will be in accordance with stated quality control values in EM-1110-2-1003. Upon request, the Government will provide the survey line files by which surveys are run.

d. Government Equipment: The following survey equipment (or comparable) will be used by the Government Survey Crew during the collection of sounding data and will be considered the standard for which data is obtained:

Positioning: Applanix Wavemaster or Applanix POS MV 4 Multibeam: RESON T-50 MB Singlebeam: ODOM CV100 ECHOSOUNDER with an 3 degree 200khz transducer AML Velocity Probe AML Sound Velocity Profiler

01 22 00.00 82-3 AMD #0002

Note: The Government will be available by request to run side-by side survey checks between the Contractor's and Government's survey vessels prior to the start of work. The Contractor must request any side-by-side survey checks at least seven days in advance of the desired date.

e. Cubic yard volumes will be computed by comparing the Government's pre-dredge and post-dredge soundings against the advanced channel design template. The Government intends to use Hypack software to compute pay volumes using the Triangulated Irregular Network (TIN) surface volume computation method. Computed pay volumes will be the difference between the TIN to CHANNEL computation of the post-dredge survey, and the TIN to CHANNEL computation of the pre-dredge survey.

No adjustments will be made for infill material (Y1) from any cause.

See Section 35 20 23.00 82, DREDGING AND CHANNEL CLEARING, regarding estimation of non-payable material.

f. All Contractor owned equipment including all attendant plant and anchor lines must be removed from the acceptance area prior to the initiation of a Government survey. If equipment remains in the acceptance area at the time of survey; the survey will be cancelled and the full daily rate for a Government survey crew shown in paragraph QUANITITY SURVEYS, below will be charged.

h. For all Contractor surveys:

(1) Conduct all surveys in accordance with EM-1110-2-1003.

(2) furnish the originals of all field notes, sounding plots, and electronic survey data described in Section 01 45 00.00 82, QUALITY CONTROL (DREDGING), along with all other records relating to the survey or to the layout of the work, to the Government, who may consider them to the extent necessary to determine the amount of progress payments.

(3) Retain copies of all such material furnished to the Government.

(4) Notify the GQAR in advance of any surveys conducted and the GQAR will have the option of attending these surveys.

i. The typical cross sections shown on the Contract drawing(s) represent the anticipated pre-dredge condition prior to start of work and are not necessarily derived from the latest available survey data.

j. Survey Time Frames

(1) All requests for Government surveys must be made by submission of a Hydrographic Survey Request Template (Attachment A7). The request must be submitted to the Government representative(s) identified at the pre-construction conference. The dredge, including all attendant plant and anchor lines must be clear of the acceptance area(s) before a survey is made. The Government Survey periods stated below are contingent on weather and sea conditions.

01 22 00.00 82-4 AMD #0002

(2) All survey requests must be submitted a minimum of three calendar days prior to the date on which the survey is required .

(3) The Government will perform all post dredge surveys within five calendar days of the requested date and will provide acceptance or rejection of each area within one day following the survey. The complete layout or post dredge package (i.e.

electronic survey data, layout chart, quantity computations) will be available two calendar days thereafter.

(4) Remain onsite until the post-dredge survey indicates the required / acceptable depths have been reached and the Government has accepted each area. In the event that the Contractor departs a work area prior to receiving final acceptance and the Government does not accept the work and requires cleanup dredging, all costs associated with the subsequent remobilization(s) to and from the unaccepted work area will be the responsibility of the Contractor

(5) The Government may conduct periodic progress surveys at all work locations. Notify the GQAR in advance of any surveys conducted and the GQAR will have the option of attending these surveys. Conduct all surveys in accordance with EM-1110-2-1003.

k. Request in writing for additional information for each survey, to include:

(1) Daily Report of Hydrographic Survey Operations

(2) Metadata

(3) Type of Survey: Multi- or Single-Beam

(4) Bar Check Calibration

(5) Sound Velocity Profile Report

(6) Survey Tide File Log

(7) Lead Line Report (when applicable)

(8) Copy of Field Book (scanned)

(9) Computation Report: The computation report will indicate the surveys used (identified by location and date) and the program and computation method used.

m. In the event it becomes necessary to reschedule a request for survey, notify the Government at least one calendar day prior to the first day of the scheduled survey period. Failure to provide such notification will result in a charge of one-half the daily rate for a Government survey crew as stated in Subpart 3.3.2(n). If the survey party mobilizes to the site before the survey is cancelled, the full daily rate for a Government survey crew will be charged.

n. Should more than one sounding or sweeping operation by the Government over an area be necessary by reason of work for the removal of shoals disclosed at a prior sounding or sweeping, the cost of such

01 22 00.00 82-5 AMD #0002

second and any subsequent sounding or sweeping operation will be charged at the rate of $3,500 per day for each day in which the Government plant is engaged in sounding or sweeping and/or is enroute to or from the site or held at or near the said site for such operations.
