BASE BID ITEMS

A. Item Number 0001, "Mobilization and Demobilization for Dredging and Disposal".

Payment will be made for costs associated with mobilization and demobilization for dredging operations and disposal operations as defined in Special Contract Requirements clause "PAYMENT FOR

MOBILIZATION AND DEMOBILIZATION".

Unit of measure: Job.

B. Item Number 0002, "Maintenance Dredging of 10-Foot Anchorage to -8ft MLLW with Disposal at Cape Cod Bay Disposal Site (CCBDS)".

C. Item Number 0003, "Maintenance Dredging of 10-Foot Channel to -10ft MLLW with Disposal at Cape Cod Bay Disposal Site (CCBDS)".

The contract price per cubic yard for Payment Item Numbers 0002 and 0003 shall include all costs for the removal of shoaled materials encountered from dredging the Federal Navigation Project (FNP) anchorage and channel, respectively, to the specified depths, and the transportation to and disposal of the dredged material at the Cape Cod Bay Disposal Site (CCBDS), as specified in Section 35 20 23 MECHANICAL

DREDGING.

The total amount of material removed, transported and placed in CCBDS and paid for under the contract for this Item will be measured by the cubic yard in place by computing the volume between the bottom surface shown by soundings of the last pre-dredge survey made before dredging begins and the bottom surface shown by the soundings of an after-dredge survey made as soon as practicable after the removal of the material.

Dredged material will be included that is within the limits of the side slopes and specified overdepths as described in Section 35 20 23 MECHANICAL DREDGING, paragraph "Dredging Limits", less any deductions that may be required for misplaced material described in subparagraph "Non-Designated Disposal Sites".

The contract drawings are believed to accurately represent conditions existing on the date of the survey shown on the drawings, but the depths and the specific areas to be dredged shown thereon may be verified and corrected by soundings taken by the Government before dredging begins. Determination of quantities removed and the deductions made to determine quantities after having once been made by the Contracting Officer, will not be reopened, except on evidence of collusion, fraud, or obvious error. Refer to Special Contract Requirements, subpart "Contract Drawings and Specifications" for additional information and requirements regarding contract drawings.

Monthly partial payments will be based on approximate quantities determined by Contractor quality control surveys. The pre-dredge survey made immediately before dredging, and the after dredge survey made as soon as practicable after the removal of the material, will be performed by the Government at no cost to the Contractor.

Unit of measure: Cubic Yard (CD).
