AMENDMENT NO. 0001

PART 1 GENERAL

1.1 COMMENCEMENT, PROSECUTION, AND COMPLETION OF WORK (APR 1984) (FAR

52.211-10)

The Contractor shall be required to:

(a) Commence work under this contract within 10 calendar days after the date the Contractor receives the Notice to Proceed

(b) Prosecute the work diligently, and

(c) AMD#1 Complete the entire work ready for use not later than 245 calendar days after the date the Contractor receives the notice to proceed. The time stated for completion shall include final cleanup of the premises.

1.2 LIQUIDATED DAMAGES - CONSTRUCTION (SEPT 2000) (FAR 52.211-12)

(a) If the Contractor fails to complete the work within the time specified in the contract, the Contractor shall pay liquidated damages to the Government in the amount of $3,640.00 for each calendar day of delay until the work is completed or accepted.

(b) If the Government terminates the Contractor's right to proceed, liquidated damages will continue to accrue until the work is completed. These liquidated damages are in addition to excess costs of repurchase under the Termination clause.

1.3 PHYSICAL DATA (APR 1984) (FAR 52.236-4)

Data and information furnished or referred to below is for the Contractor's information. The Government shall not be responsible for any interpretation of or conclusion drawn from the data or information by the Contractor.

(a) The indications of physical conditions on the drawings and in the specifications are the result of site investigations by surveys.

(b) Weather Conditions. Under ordinary conditions, the mean tidal range is about 1.5 feet. The height of tide is largely dependent on the force, direction, and duration of the wind. Strong northerly winds may depress the water surface as much as, and in some instances more than 3.0 feet below Mean Lower Low Water (MLLW), while southerly winds may raise the water surface as much as, and in some instances more than

1.7 feet above MLLW.

(c) Transportation Facilities. The immediate vicinity is served by railroad, highway, and deep and shallow draft channels. The work site is accessible by water via the Houston Ship Channel and Galveston Bay from embarkation points at surrounding public and private boat ramps.

DOCUMENT 00 73 00.01 45 Page 2

(d) Other Information. Channel traffic consists of deep draft ships, small boats of various sizes, fishing vessels, ferries, tugs, tows consisting of a tug and one or more barges. Traffic will interfere with dredging operations to some extent.

The general shape of the existing section of channel to be dredged is shown by cross sections on the Contract drawings. The Contractor is caustioned that portions of the Bayport to Morgans Point reach of the Houston Ship Channel have been previously mined to depths as great as 70 feet. Material which has settled in these mined areas is expected to be unconsolidated.

1.4 EQUIPMENT OWNERSHIP AND OPERATING EXPENSE SCHEDULE(MAR 1995)

(a) This special contract requirement does not apply to terminations. See 52.249-5000, Basis for Settlement of Proposals, and FAR Part 49.

(b) Allowable cost for construction and marine plant and equipment in sound workable condition owned or controlled and furnished by a contractor or subcontractor at any tier shall be based on actual cost data for each piece of equipment or groups of similar serial and series for which the Government can determine both ownership and operating costs from the con-tractor's accounting records. When both ownership and operating costs cannot be determined for any piece of equipment or groups of similar serial or series equipment from the contractor's accounting records, costs for that equipment shall be based upon the applicable provisions of EP 1110-1-8, Construction Equipment Ownership and Operating Expense Schedule, Region VI. Working conditions shall be considered to be average for determining equipment rates using the schedule unless specified otherwise by the contracting officer. For equipment not included in the schedule, rates for comparable pieces of equipment may be used or a rate may be developed using the formula provided in the schedule. For forward pricing, the schedule in effect at the time of negotiations shall apply. For retroactive pricing, the schedule in effect at the time the work was performed shall apply.

(c) Equipment rental costs are allowable, subject to the provisions of FAR 31.105(d)(ii) and FAR 31.205-36, Rental Costs. Rates for equipment rented from an organization under common control, lease-purchase arrangements, and sale-leaseback arrangements, will be determined using the schedule, except that actual rates will be used for equipment leased from an organization under common control that has an established practice of leasing the same or similar equipment to unaffiliated lessees.

(d) When actual equipment costs are proposed and the total amount of the pricing action exceeds the SAT, the contracting officer shall request the contractor to submit either certified cost or pricing data, or partial/limited data, as appropriate. The data shall be submitted on Standard Form 1411, Contract Pricing Proposal Cover Sheet.

NOTE: A copy of EP 1110-1-8, "CONSTRUCTION EQUIPMENT OWNERSHIP AND OPERATING EXPENSE SCHEDULE," is available at the following website:

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. AMD#1 The Contractor shall use a pipeline dredge in performing the work on the Houston Ship Channel and Bayport Docks; however, the Contractor may only use a mechanical dredge with scow to dredge the Bayport Flare. Pipeline dredge with scow or hopper dredge shall not be used to dredge the Bayport Flare.

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 VARIATION IN ESTIMATED QUANTITIES. 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

SECTION 35 20 23.16 45 Page 3 specified, after having once been made will not be reopened, except on evidence of collusion, fraud, or obvious error.

1.3.2 Vertical Datum

The channel template provided in the drawings is referenced to Mean Lower Low Water (MLLW) vertical datum. Previous dredging contracts in this reach of the Houston Ship Channel and Bayport Docks have been referenced to Mean Low Tide (MLT) datum. Cross sections in the drawings have been overlaid with after-dredge surveys from the previous dredging contract, converted to MLLW datum.

1.6 MATERIAL TO BE REMOVED

The material to be removed is shoals which have accumulated over a period of time. However, some virgin material may be encountered in allowable overdepth, or side slope dredging. Portions of the areas to be dredged have not been dredging since Hurricane Harvey. Dredging in other sections of Houston Ship Channel post-Harvey have noted higher percentages of sand than on typical maintenance contracts. Bidders are expected to examine the worksite and the records of previous dredging, which are available in the Houston Resident Office and after investigation decide for themselves the character of materials.

1.6.1 Debris Within the Dredging Limits

Debris including but not limited to, metal bands, pallets, pieces of broken cable, rope, stumps, and broken piles may be encountered. Debris removed from the dredged area is to be removed from the water. Disposal is to be the responsibility of the Contractor and disposal is to be outside the limits of Government property. If the actual conditions differ from those stated or shown, an adjustment in Contract price or time of completion, or both, will be made in accordance with the CONTRACT CLAUSE entitled

DIFFERING SITE CONDITIONS.

1.7 EASEMENTS

Permits authorizing placement of dredge material in the Placement Area(s), are attached at the end of the specification. The instruments authorizing the laying of shore pipelines may contain certain restrictions relative to specific route, location, and general use of the land. These instruments form a part of these specifications and the Contractor is to strictly comply with the terms thereof.

1.8 UTILITIES ACROSS THE LIMITS OF DREDGING

It is the Contractor's responsibility to investigate the location of utility crossings. The Contractor is to take precautions against damages which can result from dredging operations in the vicinity of the utility crossings. If damage occurs as a result of dredging operations, the Contractor will be required to suspend dredging until the damage is repaired and approved. Costs of these repairs and downtime of the dredge and attendant plant is to be at the Contractor's expense.

1.15.1 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.

SECTION 35 20 23.16 45 Page 7

1.15.2 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.

1.16 INSPECTION

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

1.16.1 Equipment

At the request of the Government, the Contractor shall 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.

1.16.2 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.

1.17 QUANTITY SURVEYS

(1) Quantity surveys shall be conducted, and the data derived from these surveys shall be used in computing the quantities of work performed and the actual construction completed and in place.

(2) The Contractor shall conduct surveys for any periods for which progress payments are requested. These surveys shall be conducted under the direction of a representative of the Contracting Officer, unless the Contracting officer waives this requirement in a specific instance. The Government will make the computations that are necessary to determine the quantities of work performed or finally in place. The Contractor shall make the computations based on the surveys for any periods for which progress payments are requested.

(3) Promptly upon completing a survey, the Contractor shall submit the originals of field notes and other records relating to the survey or to the layout of the work to the Contracting Officer, who will use them as necessary to determine the amount of progress payments. The Contractor shall retain copies of the material submitted to the Contracting Officer.

SECTION 35 20 23.16 45 Page 8

1.18 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 obstruction to navigation, 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 $6,709.00 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.

1.18.1 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.

1.19 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.

1.20 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 and could include unanticipated shoals in the Houston Ship Channel Complex. Dredging would consist of limited portions of a section of channel, intended to remove critical shoals hindering commercial navigation. 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.

1.21 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, SECTION 35 20 23.16 45 Page 9 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 10,000 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.

1.22 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 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.
