DREDGING

AMENDMENT NO. 0003

PART 1 GENERAL

1.1 SUMMARY

The work in this Section consists of furnishing plant, labor, materials, and equipment to perform the operations necessary for the removal of sediment debris to the required dimensions shown, satisfactory disposal thereof, and other operations incidental thereto. The Contractor may use either (AM#3)pipeline or mechanical dredge(s) , or combination of both, in performing the work. All dredged materials must be placed in the Placement Areas designated in this Contract.

1.2 MEASUREMENT AND PAYMENT

Measurement and payment for 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. Survey data has been posted to EM Public website:

http://www.swg.usace.army.mil/Business-With-Us/Emergency-Management-Office/ 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, SECTION 35 20 23.16 45 Page 3 after having once been made will not be reopened, except on evidence of collusion, fraud, or obvious error.

1.12.1 General Requirements

Keep the necessary dredge equipment and attendant plant on the job to meet the requirements of the work. The dredge equipment and attendant plant is to be in satisfactory operating condition and capable of safely and efficiently performing the work as set forth in specifications and be subject to inspection by the Contracting Officer's representative at all times.

1.12.2 Capacity

No reduction in the capacity of the dredge equipment and attendant plant employed to execute the work is to be made except by written direction of the Contracting Officer. The measure of the "Capacity of the Dredge and Attendant Plant" is to be its actual performance on the work to which these specifications apply.

1.13 INSPECTION

The Government will supervise the maintenance of the gages, ranges, location marks, and limit marks in proper order and position; but the presence of the inspector will not relieve the Contractor of responsibility for the proper execution of the work in accordance with the specifications. The Contractor is required to furnish the following items.

SECTION 35 20 23.16 45 Page 6

1.13.1 Equipment

At the request of the Government, the Contractor will furnish the use of boats, boatmen, laborers, and material forming a part of the ordinary and usual equipment and crew of the dredging plant as may be reasonably necessary in inspecting and supervising the work. However, the Contractor will not be required to furnish facilities for the surveys, specified in the Paragraph: FINAL EXAMINATION AND ACCEPTANCE.

1.13.2 Transportation

At the request of the Government, the Contractor shall furnish suitable transportation from all points on shore designated by the Contracting Officer to and from the various pieces of plant, and to and from the Placement Areas. If the Contractor refuses, neglects, or delays compliance with these requirements, the specific facilities may be furnished and maintained by the Contracting Officer, and the cost thereof will be deducted from the amounts due or to become due the Contractor.

1.14 FINAL EXAMINATION AND ACCEPTANCE

As soon as practicable after the completion of the entire work or any section thereof, if the work is divided into sections and in the opinion of the Contracting Officer will not be subject to damage by further operations under this Contract, this work will be thoroughly examined at the expense of the Government by sounding or by sweeping, or both, as directed. If shoals, lumps, or other lack of Contract depth are disclosed by this examination, the Contractor will be required to remove same by dragging the bottom or by dredging at the Contract rate for dredging but, if the bottom is soft and the shoal areas are small and form no material major obstruction to water flow, the removal of the shoal may be waived at the discretion of the Contracting Officer. The Contractor or its authorized representative will be notified when soundings or sweepings are to be made and will be permitted to accompany the survey party. When the area is found to be in a satisfactory condition it will be accepted finally. If more than two sounding or sweeping operations by the Government over an area are necessary, by reason of work for the removal of shoals disclosed at a prior sounding or sweeping, the cost of the third and any subsequent sounding or sweeping operations will be charged against the Contractor at the rate of $6,731.02 per day for each day in which the Government plant is engaged in sounding or sweeping or is enroute to or from the site or held at or near the site for these operations.

1.14.1 Acceptance

Final acceptance of the whole or a part of the work and the deductions or corrections of deductions made thereon will not be reopened after having once been made, except on evidence of collusion, fraud, or obvious error, and the acceptance of a completed section will not change the time of payment of the retained percentages of the whole or any part of the work.

1.15 SHOALS

If, before this Contract is completed, shoals occur in a section previously accepted, redredging at the Contract price, within the limit of available funds, may be done if agreeable to both the Contractor and the Contracting Officer.

SECTION 35 20 23.16 45 Page 7

1.16 UNANTICIPATED SHOALING

During the course of this Contract, unanticipated dredging requirements may develop that require the use of the Contractor and Contractor's plant. The dredging required would be similar in scope to that required under the current contract. Dredging would consist of limited portions of a section of channel, intended to remove critical shoals. If such a need arises, the Contracting Officer may issue a Request for Proposal for the work under the CONTRACT CLAUSE entitled CHANGES, and the work performed upon the execution of a bilateral contract modification.

1.17 VARIATIONS IN ESTIMATED QUANTITIES - DREDGING

Where the quantity of a pay item in this Contract is an estimated quantity and where the actual quantity of material within the required dredging prism varies, an equitable adjustment will be processed in accordance with FAR 52.211-18, VARIATION IN ESTIMATED QUANTITY (April 1984). The equitable adjustment applies only to the quantity within the required dredging prism, which does not include the allowable overdepth.

If the total quantity of material to be paid for and actually removed under this Contract exceeds the limit established by FAR 52.211-18, VARIATION IN ESTIMATED QUANTITY (April 1984), an additional time will be allowed at the rate of 1 calendar day for each (AM#3)6,500 cubic yards in excess of the established limit. The Contractor is not to exceed the estimated quantities in the Contract Line Items without prior authorization and only with a signed modification issued by the Contracting Officer.

1.18 QUANTITY SURVEYS

1.18.1 General

Quantity surveys are to be conducted, and the data derived from these surveys are to be used in computing the quantities of work performed and the actual construction completed and in place.

1.18.2 Dredging Sections

The Government will conduct the original and final surveys and make the computations based on them. The Contractor is to conduct the surveys for the periods when progress payments are requested and make the computations based on these surveys. Surveys conducted by the Contractor will be conducted under the direction of the Contracting Officer, unless the Contracting officer waives this requirement in a specific instance.

1.18.3 Submittals

Promptly upon completing a survey, submit the originals of every field note and other record relating to the survey or to the layout of the work in accordance with the SECTION 01 33 00 SUBMITTAL PROCEDURES. The Contracting Officer will use them as necessary to determine the amount of progress payments. Retain copies of submitted material.

1.19 CONTINUITY OF WORK

No payment will be made for work done in an area designated by the Contracting Officer until the full depth required under this Contract is secured in the whole of this area, unless prevented by ledge rock, nor

SECTION 35 20 23.16 45 Page 8 will payment be made for excavation in an area not adjacent to and in prolongation of areas where full depth has been secured except by decision of the Contracting Officer. If a non-adjacent area is excavated to full depth during the operations carried on under this Contract, payment for the work therein may be deferred until the required depth has been reached in the area intervening. The Contractor may be required to suspend dredging when the gages or ranges cannot be seen or properly followed.
