The contractor's final payment will be based on the Government's prior and after dredge survey.

SECTION 01 22 00.00 10 Page 5

1.3.1.2 MEASUREMENT

The Contractor must, in the presence of the COR, take soundings after dredging to confirm that the proposed dredging depths have been completed for progress payments. Perform surveys in accordance to Section 35 20 23 , DREDGING. The program and methods for calculating quantities for progress payments must be submitted in the dredging plans and agreed to prior to pre-dredging survey by the Contractor. The Contractor should note that the river dredge areas shown on the plans are possible areas to be dredged and are for bidding purposes. The actual area(s) selected to be dredged will be determined utilizing the pre-dredge survey completed by the Government.

(a) Method of Measurement. The total amount of materials removed and to be paid for under the contract will be measured by the cubic yard in place by computing, within the limits of the allowances and tolerances the volume between the bottom surfaces shown by the prior and after survey soundings. The Government shall complete the final "after dredging survey" as soon as practicable after all work specified has been completed. Results of soundings will be the basis for final payment.

(b) During Progress of Work. The contract drawings are believed to accurately represent the conditions existing at the time of survey, however, all soundings of the proposed dredging areas shown on the drawings shall be verified and corrected by a "prior dredging survey" taken by the Government before dredging occurs. The contract depth will be determine by soundings or sweeping taken behind the dredge as work progresses. The Contractor shall take progress soundings or sweepings. The measurement and computation of payable quantities within the allowances and tolerances described in this section after having once been made, will not be reopened, except on evidence of collusion, fraud, or obvious error.

(c) Excessive Dredging. Material taken from beyond the limits specified in paragraphs "Allowable Dredging Prism" and "Side Slope" of Section 35 20 23 DREDGING, will be deducted as excessive channel or sideslope dredging, from the total amount dredged for which payment will not be made. The final determination of the amounts of excessive dredging will be based wholly on the surveys made for final examination and acceptance.

(d) Progress Payment Quantity Surveys. Progress Payment Quantity Surveys shall be performed in accordance with the class I Contract Payment Survey as specified in EM 1110-2-1003 . Additional soundings will be taken as the COR may deem necessary.

(e) Monthly Estimate. Monthly estimates of work completed will be based on the result of soundings taken during the progress of the work based on an estimated percent of completion. Deductions will be made for dredging and disposal not in accordance with the specifications.

3.1 CONTRACT COST BREAKDOWN

The Contractor must furnish within 30 calendar days after the date of Notice to Proceed, and prior to the submission of its first partial payment estimate, a breakdown of its single job pay item or items which will be reviewed by the Contracting Officer as to propriety of distribution of the total cost to the various accounts.
