PART 1 GENERAL

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

52.211-10) AM#2

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) Complete the entire work ready for use not later than 290 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 $3,266.00 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 3

(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 cautioned that portions of the Bayport to Morgan Point reach of the Houston Ship Channel has 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:

AMENDMENT NO. 0002

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. The Contractor shall use a pipeline dredge in performing the work for the Sections 1 through 7 of the Houston Ship Channel, Section 8 through 13 of Bayport Ship Channel, Section 14 of Barbours Flare , Section 15 of PHA Docks at Bayport, and Section 16 and 17 of PHA Docks at Barbours.

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 52.211.18 VARIATION IN ESTIMATED QUANTITY. 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: MATERIAL TO BE REMOVED 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 AM#2

The drawings already prepared as specified in the CONTRACT CLAUSE 252.236-7001 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 l at est sur veys avai l abl e on https://www.swg.usace.army.mil/Missions/Navigation/Hydrographic-Surveys/Galveston-Texas-City-Houston/ The dept hs and el evat i ons shown wi l l be ver i f i ed and cor r ect ed by f at homet er soundi ngs t aken by t he Gover nment bef or e dr edgi ng. The depths and elevations shown will be verified and corrected by fathometer soundings taken by the Government before dredging. The Government will

SECTION 35 20 23.16 45 Page 3 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.

SECTION 35 20 23.16 45 Page 8

1.17 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 $10,027.00 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.

1.17.1 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.

1.18 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.

1.19 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 hindering commercial navigation. If such a need arises, the Contracting Officer may issue a Request for Proposal for the work under the CONTRACT CLAUSE 52.243-4 CHANGES, and the work performed upon the execution of a bilateral contract modification.

1.20 VARIATION 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 CONTRACT CLAUSE 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.

SECTION 35 20 23.16 45 Page 9

If the total quantity of material to be paid for and actually removed under this Contract exceeds the limit established by CONTRACT CLAUSE 52.211-18, VARIATION IN ESTIMATED QUANTITY (April 1984), an additional time will be allowed at the rate of 1 calendar day for each 12,000 cubic yards in excess of the established limit for the work in Schedule No. 1 and Options No. 2 and 4, and 1 calendar day for each 6,000 cubic yards in Options No. 1 and 3. 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.

1.21 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.

52.242-14 SUSPENSION OF WORK or any other provision under this Contract.

PART 3 EXECUTION

3.1 ESTIMATED QUANTITY OF MATERIAL

Within the limits of available funds, the Contractor will be required to excavate the entire quantity of material necessary to complete the work specified whether the quantities involved are greater or less than those estimated.

3.1.1 Quantity Summary

The quantities listed in Appendix 1 - QUANTITY SUMMARY TABLE include the volumes present at the time of the surveys indicated on the Contract drawings, plus anticipated shoaling before dredging begins. For the purpose of acceptance, the pipeline dredging work in the Bid Item(s) of the Bid Schedule are divided into Sections.

3.1.2 Required Dredging Prism

The total estimated amount of material to be removed from within the specified limits, including side and end slopes and including anticipated shoaling occurring prior to the dates of the "before-dredging" surveys but excluding overdepths, in cubic yards is listed in Appendix 1 - QUANTITY

SUMMARY TABLE.

3.1.3 Allowable Overdepth

To cover unavoidable inaccuracies of the dredging process, material actually removed from the designated areas to be dredged, will be measured and paid for at full Contract price. The maximum amount of allowable overdepth dredging is estimated, including anticipated shoaling occurring prior to the dates of the "before-dredging" surveys in cubic yards is listed in Appendix 1 - QUANTITY SUMMARY TABLE.

3.1.4 Side And End Slopes

Dredging of the side and end slopes are to follow, as closely as practicable, the lines indicated or specified. Material actually removed from within the limits as approved, to provide for final side and end slopes as specified, but not in excess of the amounts originally above the limiting side and end slopes will be estimated and paid for, whether dredged in original position or by dredging the space below the pay slope plane at the bottom of the slope for upslope material capable of falling into the cut. In computing the limiting amount of side and end slope dredging, net dimensions, without allowance for overdepth, will be used.

3.1.5 Excessive Dredging

Material taken from beyond the limits specified will be deducted from the total amount dredged as excessive overdepth dredging or excessive side or end slope dredging, for which payment will not be made. Nothing herein is to be construed to prevent payment for the removal of shoals performed in accordance with the applicable provisions of the Paragraph FINAL EXAMINATION AND ACCEPTANCE or Paragraph SHOALS.

SECTION 35 20 23.16 45 Page 11

3.2 AREAS TO BE DREDGED

Based on information currently available to the Government, areas known to require dredging are shown.

3.3 CONDUCT OF DREDGING WORK

3.3.1 Pre-Operations Safety Coordination Meeting

Prior to arrival on location and commencing dredge operations, the Contractor is to attend a pre-dredging safety coordination meeting between the dredge operators, pilots, towing industry representatives, VTS, and the affected port. It is the Contractor's responsibility to contact Houston Vessel Traffic Service (VTS) at 281-464-4837 to coordinate and schedule this meeting. Contractor is to inform the Government at least 48 hours prior to the scheduled meeting so that a Government Representative may attend.

3.3.2 Protection of Existing Waterways

Conduct dredging operations using a method that will ensure that material or other debris are not pushed outside of the dredging limits or otherwise deposited in existing side channels, basins, docking areas, or other areas being used by vessels. The Contractor will be required to change its method of operations as may be required to comply with the above requirements. If bottom material or other debris is pushed into areas noted above, as a result of the Contractor's operations, the same is to be promptly removed by and at the expense of the Contractor to the satisfaction of the Contracting Officer.

3.3.3 Adjacent Property and Structures

Dredging adjacent to a structure will not be permitted closer than that shown. Damage to private or public property or structures resulting from the disposal or dredging operations are to be repaired promptly by and at the Contractor's expense. Damage to structures as a result of Contractor's negligence will result in suspension of dredging and require prompt repair at the Contractor's expense as a prerequisite to the resumption of dredging. Where dredging to obtain the required dimensions might endanger a structure, the Contracting Officer, upon request, may reduce the required excavation in the vicinity of this structure.

3.4 PLACEMENT OF EXCAVATED MATERIAL

3.4.1 General

Material excavated is to be transported to and deposited in the Placement Area designated. Inspect the Placement Area to ensure that using the Area for placement operations will not place it in violation of the applicable Federal, State, or local statutes concerning fish and wildlife.

Particular statutes which the Contractor to be consider include, but are not limited to, the Federal Migratory Bird Treaty Act and the Endangered Species Act of 1973.

3.4.1.1 Misplaced Material

Material will not be deposited or allowed to flow into project channels or into a bayou, stream tributary to the Channel, or into an existing drainage outlet ditch, canal, water intake or outlet facility, nor will

SECTION 35 20 23.16 45 Page 12 materials be allowed to flow onto improved areas including highways and roads in or adjacent to the Placement Area. If a stream, bayou drainage outlet, ditch, canal, water intake or outlet facility becomes shoaled as a result of the pipeline dredging or placement operations, promptly remove these shoals and the material will be placed in the Placement Area.

Dragging or washing operations to remove the shoals will not be permitted.

3.4.1.2 Placement Operations Inspection

Adequately inspect placement operations in the Placement Area(s) daily to reduce the possibility of accidental breaching of dikes and spillway with resulting spillage of dredged materials outside the Area. If dike failures occur while materials are being pumped into the Placement Area, dredging operations are to be stopped immediately, and the deposit of material in the Area is not to be resumed until the confining structures have been restored to an approved condition. Holes dug on the banks for deadmen or where anchorage are to be filled. Confined areas are to be maintained in an operational condition until completion and acceptance of the work under this Contract.

3.4.1.3 Placement Area Drainage

Deposited materials will not impound water or impede natural drainage. If necessary, excavate and maintain ditches to drain the low areas in the dredged material and Placement Area to the weirs. The ditches are to be of adequate number and size to eliminate ponding of water within the limits of the Placement Area.

3.4.1.4 Maintenance of Existing Dike and Drop-outlet Structures

It is the responsibility of the Contractor to verify the current condition of the dike prior to commencement of dredging and to notify the Contracting Officer of slumped or failed areas where there appears to be a potential for failure or overtopping during ponding. The Contractor will have the responsibility of continually monitoring the dike condition and to maintain the dike in a condition and elevation equal to or better than the condition of the dike at the date of this Contract award. Construct temporary access from the existing roadway to each drop-outlet structure in each Placement Area.

3.4.2 Spillway Operations

Once placement operations are completed in a confined area for which the Placement Area is being used, the boards on the spillway of that Placement Area are to be removed at a proper rate to allow drainage of the Area. In confined areas, dike and spillway work required is to be completed and accepted prior to placement operations in that Area. Spillways are to be operated in general accordance with guidelines contained in the Engineering Manual EM 1110-2-5025 entitled "Confined Disposal of Dredged Material" , to maintain uniformity of weir elevation around the drop-out structure, as is practicable, during discharge of effluent. Boards are to be uniform in width and of proper length so insertion and removal is not difficult. Cracked, warped or boards of improper length are to be replaced. Seepage between boards during ponding is to be eliminated using plastic sheeting or other effective methods.
