SPECIAL CONTRACT REQUIREMENTS, STANDARD

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 of acknowledgement of Notice to Proceed

(b) Prosecute the work diligently, and

(c) Complete the entire work ready for use not later than 105(AM#1)97 calendar days after date of acknowledgment of Notice to Proceed. The time stated for completion shall include final cleanup of the premises.

1.2 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 2.0 feet below Mean Low Low Water (MLLW), while southerly winds may raise the water surface as much as, and in some instances more than

3.0 feet above MLLW.

(c) Transportation Facilities. The immediate vicinity is served by railroad, highway, and deep and shallow draft channels.

(d) Condition of Channel. The general shape of the existing section of channel to be dredged is shown by cross sections on the Contract drawings.

(e) Channel Traffic. Channel traffic consists of large seagoing vessels, fishing vessels and tugs with barges. Traffic will interfere with dredging operations to some extent.

1.3 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 $1,406.00 for each calendar day of delay until the work is completed or accepted.

DOCUMENT 00 73 00.01 45 Page 2

(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.

1.4 OBSTRUCTION OF NAVIGABLE WATERWAYS (DEC 1991)(DFARS 252.236-7002)

(a) The Contractor shall

(1) Promptly recover and remove material, plant, machinery, or appliance which the Contractor loses, dumps, throws overboard, sinks, or misplaces and which, in the opinion of the Contracting Officer, may be dangerous to or obstruct navigation;

(2) Give immediate notice, with description and locations of such obstructions, to the Contracting Officer; and

(3) When required by the Contracting Officer, mark or buoy such obstructions until the same are removed.

(b) The Contracting Officer may

(1) Remove the obstructions by contract or otherwise should the Contractor refuse, neglect or delay compliance with paragraph (a) of this clause; and

(2) Deduct the cost of removal from any monies due or to become due the Contractor, or

(3) Recover the cost of removal under the Contractor's bond.

(c) The Contractor's liability for the removal of a vessel wrecked or sunk without fault or negligence shall be limited to that provided in Sections 15, 19, and 20 of the River and Harbor Act of March 3, 1899 (33 U.S.C. 410, et seq).

1.5 EQUIPMENT OWNERSHIP AND OPERATING EXPENSE SCHEDULE (CESWG)

This Paragraph does not apply to terminations. See UAI 52.249-5000, Basis for settlement of proposals and FAR PART 49.

1.5.1 Allowable Cost

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 Contractor'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

DOCUMENT 00 73 00.01 45 Page 3 retroactive pricing, the schedule in effect at the time the work was performed shall apply.

1.5.2 Equipment Rental

Equipment rental costs are allowable, subject to the provisions of FAR 31.105(d)(ii) and FAR 31.205-36. 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.

1.5.3 Actual Equipment Costs

When actual equipment costs are proposed and the total amount of the pricing action exceeds the small purchase threshold, the Contracting Officer shall request the Contractor to submit either certified cost or pricing data, or partial and limited data, as appropriate. The data shall be submitted on Standard Form 1411, Contract Pricing Proposal Cover Sheet.

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 for Sabine Neches Waterway 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 shall include the costs for maintenance of levees 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.

1.6 CHARACTER OF MATERIAL

The material to be removed in the SNWW is shoals which have accumulated over a period of time. However, some virgin material may be encountered in allowable overdepth, or side slope dredging. The material to be removed in the Port of Port Arthur area are shoals which have accumulated over a period of time and virgin material. Virgin material will be encountered in the required depth, allowable overdepth, and side slope for dredging between Station No. 0+00 to 19+65 (Berth Nos. 3, 4 & 5). Bidders are expected to examine the worksite and the records of previous dredging, which are available in the Port Arthur Resident Office and after investigation decide for themselves the character of materials.

SECTION 35 20 23.17 45 Page 4

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 shall be removed from the water. Disposal shall be the responsibility of the Contractor and disposal shall 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 the laying of shore pipe, and for placement of dredge material in the Placement Area No. 8, are on file and available for examination in the Port Arthur Resident Office of the U.S. Army Corps of Engineers, 8737 9th Avenue, Port Arthur, Texas.

PART 3 EXECUTION

3.1 ESTIMATED QUANTITY OF MATERIAL

Within the limits of available funds, the Contractor will be required to

SECTION 35 20 23.17 45 Page 8 excavate the entire quantity of material necessary to complete the work specified whether the quantities involved are greater or less than those estimated. The work is to be done in accordance with this Contract and at the Contract price or prices, subject to the provisions of the SECTION 01 10 00.01 45 NON-REGULATED SPECIAL CONTRACT REQUIREMENTS, Paragraph entitled VARIATIONS IN ESTIMATED QUANTITIES - DREDGING.

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 Bidding 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 shall 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 shall be construed to prevent payment for the removal of shoals performed in accordance with the applicable provisions of the SECTION 01 10 00.01 45 NON-REGULATED SPECIAL CONTRACT REQUIREMENTS, Paragraph FINAL EXAMINATION AND ACCEPTANCE or Paragraph SHOALING.

3.2 AREAS TO BE DREDGED

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

Prior to arrival on location and commencing dredge operations, the Contractor shall attend a pre-dredging safety coordination meeting between the dredge operators, pilots, towing industry representatives, VTS, and the affected port.

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 shall 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. At the Port of Port Arthur Dock, no deep dredging within 10 feet of the Dock face in Berth Nos. 3, 4 and 5, as there is inter-locking slop protection below 45 foot in those areas. All pipeline and pontoons must be continuously secured and maintained away from all dock face, support piles, cluster piles, etc. Damage to private or public property or structures resulting from the disposal or dredging operations shall 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.

3.4 PLACEMENT OF EXCAVATED MATERIAL

3.4.1 General

Material excavated shall 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 shall 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 shall 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 shall 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 shall be placed in the Placement Area. Dragging or washing operations to remove the shoals will not be permitted.

SECTION 35 20 23.17 45 Page 10

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 levees and spillway with resulting spillage of dredged materials outside the Area. If levee failures occur while materials are being pumped into the Placement Area, dredging operations shall be stopped immediately, and the deposit of material in the Area shall not be resumed until the confining structures have been restored to an approved condition. Holes dug on the banks for deadmen or anchorage shall be filled. Confined areas shall be maintained in an operational condition until completion and acceptance of the work under this Contract. The SECTION 01 10 00.01 45NON-REGULATED SPECIAL CONTRACT REQUIREMENTS, Paragraph: DAMAGE TO WORK is only applicable to damage of levees and other non-dredging items.

3.4.1.3 Placement Area Drainage

Deposited materials shall not impound water or impede natural drainage.

The Contractor shall, if necessary, excavate and maintain ditches to drain the low areas in the dredged material and Placement Area to the weirs. The ditches shall 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 Levees and Drop-outlet Structures

The available information regarding the heights and dimensions of levees and dimensions and elevations of the drop-outlet structures are contained in these Contract documents; however, it is the responsibility of the Contractor to verify the current condition of the levees 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 levees condition and to maintain the levees in a condition and elevation equal to or better than the condition of the levees at the date of this Contract award. The Contractor shall also 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 shall be removed at a proper rate to allow drainage of the Area. In confined areas, levee and spillway work required shall be completed and accepted prior to placement operations in that Area. Spillways shall be operated in general accordance with guidelines contained in the Engineering Manual EM 1110-2-5027 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 shall be uniform in width and of proper length so insertion and removal is not difficult.

Cracked, warped or boards of improper length shall be replaced. Seepage between boards during ponding shall be eliminated using plastic sheeting or other effective methods. Upon completion of discharge within a particular Area, the Contractor shall remove the boards as soon as practicable to accomplish drainage of the Area.
