The Contractor shall be responsible for establishing its own reference line to conduct hydrographic surveys and dredging operations if electronic positioning equipment is not used.

Government survey data will be processed with HYPACK 2016 software using the Kingfisher Method (updated 5/6/2016). Volumes will be computed by average end area using cross sectional survey lines. Before and After Dredge cross sections will be run at regular intervals and at changes in the template. If the Contractor elects to use HYPACK 2016 software, the Government will provide the survey line files for the Contractor's use.

1.3.1.5 Surveys During Progress of Work

Contract depth will be determined by surveys taken behind the dredge as work progresses. The Contractor shall take progress soundings or sweepings and submit drawings of the surveys.

1.3.1.6 Unit of Measurement

Unit of measure: cubic yard.

PIPELINE DREDGING

AMENDMENT NO. 0001

PART 1 GENERAL

1.1 SUMMARY

The work in this Section consists of furnishing plant, labor, materials, and equipment and performing the operations necessary for the removal of materials to the required dimensions shown, satisfactory disposal thereof, and other operations incidental thereto.

1.2 MEASUREMENT AND PAYMENT

Measurement and payment for pipeline dredging will be paid for in accordance with provisions of the SECTION 01 22 00.10 MEASUREMENT AND

PAYMENT.

1.3 WORK COVERED BY CONTRACT PRICE

Base bids on the quantity of dredging indicated. If the total quantity of dredging varies from that specified as the basis for bidding, the Contract price will be adjusted in accordance with the CONTRACT CLAUSE entitled CHANGES. The dredging conditions specified and indicated describe conditions which are known. However, the Contractor is responsible for other conditions encountered which are not unusual when compared to the conditions recognized in the dredging business as usual in dredging activities such as those required under this Contract. The Contract price for dredging will include the cost of removal and placement of the material as specified in the Paragraphs: CHARACTER OF MATERIAL and PLACEMENT OF EXCAVATED MATERIAL. The Contract price for dredging will include the costs for maintenance of dikes and ditches necessary to confine the material within the areas shown.

1.3.1 Existing Conditions

The drawings already prepared as specified in the CONTRACT CLAUSES Paragraph entitled CONTRACT DRAWINGS AND SPECIFICATIONS represent conditions existing as of the date of their preparation using average existing conditions. However, to reflect anticipated shoaling occurring between the dates of preparation of the drawings and the dates of the "before-dredging" sections, the estimated dredging quantities stated in the Bid Schedule have been adjusted accordingly. The depths and elevations shown will be verified and corrected by fathometer soundings taken by the Government before dredging. The Government will normally use a frequency of 200 kHz to conduct hydrographic surveys. If the surveys indicate the presence of fluff in the channel, a frequency of 40 kHz will be used.

Determination of quantities removed and the deductions made from them to determine quantities by in-place measurement to be paid for in the area specified, after having once been made will not be reopened, except on evidence of collusion, fraud, or obvious error.
