3.2 SUBMISSION OF INVOICES FOR PAYMENT

Submit invoices for payment as required in Section 00 73 00, Special Contract Clause INVOICE SUBMITTAL. Progress payments for work accomplished will be made monthly.

3.3 PAYMENT METHOD

3.3.1 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 1 or 2 feet beyond the required channel depth, unless otherwise noted on the associated Contact drawings.

b. 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 200 kHz single-beam, or 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.

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 and Attitude System: Applanix POS MV V5 Wavemaster Multibeam Echosounder: Teledyne RESON T-50 Singlebeam Echosounder: Teledyne ODOM CV-100 with a 3 degree 200khz transducer Sound Velocity Profiler: AML BaseX

Note: The Government will be available by request to run check surveys 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.

e. All Contractor owned equipment including all attendant plant and anchor lines must be removed from the acceptance area prior to the initiation of a survey. If equipment remains in the acceptance area at the time of survey, the survey will be cancelled and the full daily rate of $5,800 will be charged.

f. For all Contractor surveys, furnish the originals of all field notes, sounding plots, and electronic survey data described in Section

SECTION 01 22 00.00 82 Page 8

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. Retain copies of all such material furnished to the Government.

g. Survey Time Frames

(1) All requests for Government surveys must be made by submission of a Hydrographic Survey Request Form (Attachment A6). 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.

(2) All survey requests must be submitted a minimum of four calendar days prior to the date on which the survey is required, or immediately upon receiving the pre-dredge survey layout if the post-dredge survey will be needed in less than four calendar days.

(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, and quantity computations) will be available two calendar days thereafter. For the final acceptance area within a specific work location, once that acceptance area has been completed, and a post dredge survey has been requested, the Contractor may move to the next work location and begin work. However, if the results of the post dredge survey show that additional dredging is required at the previous acceptance area the Contractor will be required to return at no additional cost to the Government.

(4) The Government may conduct periodic progress surveys at all work locations.

(5) 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.

h. 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)

SECTION 01 22 00.00 82 Page 9

(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.

i. 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. If the survey party mobilizes to the site before the survey is cancelled, the full daily rate for a Government survey crew of $5,800 will be charged.

j. Several work areas within this contract will have a vertical slope on one or more side due to the close proximity of obstructions, and the inability to collect adequate survey data outside of the channel limits. In work areas with vertical slopes, bidders should consider the potential of non-pay material outside the toe line moving into the dredging prism.

k. See Attachment A13 Survey Acceptance Criteria for survey methods and acceptance language for each work location. 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. There is one exception to this requirement, per the note below.

Note:

(1) For Baker Bay areas, as identified on the contract drawings, certain parts of the channel will not be evaluated for depth clearance, and rather will be only be evaluated for clearance of the prescribed slope.

(2) For Port of Longview dredge areas, acceptance will be based on multibeam survey data processed using a median sort with a 5x5 foot matrix. Post-dredge survey soundings will be clipped to the dredge prism prior to median sorting to remove soundings outside of the dredge prism. All median sorted soundings within the dredge prism will be evaluated for acceptance.

l. The 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.

m. 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 second and any subsequent sounding or sweeping operation will be charged at the rate of $5,800 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.

NOTE: The Contractor should consider conducting some means of hydrosurvey prior to requesting a government post dredge survey for acceptance of a work area so as to avoid being assessed the fee prescribed in the paragraph above.

3.3.2 Dredging Quantity Computations

a. As prescribed in paragraph Pre/Post Dredge Survey of this Subpart, the Government will determine cubic yard quantities for payment and acceptance by utilizing electronic depth sounding and horizontal positioning equipment.

b. As required, data from land surveys will be obtained and incorporated into the volume computation.

c. The dredging pay prism is defined by the intersection of the maximum pay depth and the pay slope, as shown by Attachment A3, Descriptive Sketch. Slopes are assumed to project upward from the maximum pay depth at 1-vertical to 3-horizontal, unless noted otherwise on the Contract drawings, regardless of whether it is found to be representative of the actual side slope conditions. Material removed from outside of the maximum pay prism will not be considered for payment. Actual material removed from the side slope is considered payable as long as it is within the maximum pay prism as determined by the pre-survey data.

d. 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.

e. Material removed from the projected side slope areas that is within the maximum dredging pay prism is considered payable. No payment will be made for material removed from outside the slope projection shown on the Contract drawings.

3.3.3 Quality Assurance Surveys

A high frequency of Government performed surveys must be anticipated. The Government may elect to perform, for the Government's use, up to two quality assurance surveys in each acceptance area. These surveys are not intended to supplement or replace the Contractor's QC/progress surveys.

The Government will provide 48 hour notice prior to initiating a quality assurance survey. The Government quality assurance surveys will be conducted without impact to Contractor's operations. Government quality assurance surveys will not be used for the basis of progress payments.

3.3.4 Screened Debris Quantity Computations

a. This Subpart applies only to work associated with Transfer Site W-60.9-IW work, specifically CLINs 0010AA and 0010, 0011AA and 0011AB, and 0012AA and 0012AB.

SECTION 01 22 00.00 82 Page 11

b. As part of the PSMP, submit a Debris Measurement Plan for approval that identifies the certified scale to be used for weighing removed debris and the manner in which the debris will be transported to the scale(s), and include a copy of the weigh scale certification.

c. Notify the Government by email to the COR at least five days prior to transporting any debris for measurement to the certified scale(s).

A Government representative must be present for the measurement(s).

d. Submit the weigh ticket(s) to the Government within 24 hours of the measurement(s).
