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 SECTION 01 10 00.01 45 NON-REGULATED SPECIAL CONTRACT REQUIREMENTS, Paragraph: VARIATION IN ESTIMATED QUANTITIES - DREDGING. 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.

1.5 SUBMITTALS

Government approval is required for submittals with a "G" designation;

submittals not having a "G" designation are for information only. When used, a designation following the "G" designation identifies the office that will review the submittal for the Government. The following shall be submitted in accordance with the SECTION 01 33 00 SUBMITTAL PROCEDURES:

SD-01 Preconstruction Submittals

Notification Prior To Commencement of Dredging Operations; G

Indicate commencement of dredging operations, and location of dredge(s).

Temporary Removal of Aids To Navigation; G

SD-02 Shop Drawings

Submerged Pipeline; G

Indicate pipeline location and installation details as outlined in the Subparagraph: Submerged Dredge Pipeline.

Pipeline Route; G

A detailed pipeline diagram for each Placement Area detailing the pipeline route and anchor locations shall be submitted prior to commencing work on this project.

1.6 CHARACTER OF MATERIAL

The material to be removed is shoals which have accumulated over a period of time. This contract represents a transition from the use of the Mean Low Tide (MLT) datum to the Mean Lower Low Water (MLLW) datum. As a result, the Government anticipates that virgin material may be encountered in the allowable overdepth and/or side slope dredging. Bidders are expected to examine the worksite and the records of previous dredging, which are available upon request from the Corpus Christi 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

SECTION 35 20 23.16 45 Page 4 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(s), are on file and available for examination upon request form the Corpus Christi Resident Office of the U.S. Army Corps of Engineers, 1920 N. Chaparral, Corpus Christi, Texas 78401. 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 shall 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 shall 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 shall be at the Contractor's expense.

1.8.1 Known Pipeline/Utility Crossings

There are pipelines and or utilities which are within the work limits. The following pipeline/utilities cross the area(s) to be dredged:

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. 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.

SECTION 35 20 23.16 45 Page 10

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 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. 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. Details for dredging adjacent to structures are shown.

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 23.16 45 Page 11

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 45 NON-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.

SECTION 35 20 23.16 45 Page 12

3.4.3 Placement Area

3.4.3.1 Partially Emergent Unconfined Placement Area No. 7 and No. 8

The Placement Area shall be prominently marked by the Contractor with conspicuous buoys or stakes at each corner. The Dredge Pipeline shall generally follow the route shown. The Contractor shall limit the pipeline corridor(s) to the minimum number and width needed to accomplish access for pipeline movement and dredged material placement. Initial discharge shall begin at the approximate location shown. The dredged material shall be deposited over and beyond the crests of the highest existing mounds. A spreader at the end of the discharge pipe shall be used at this Placement Area to reduce scour and to distribute the material evenly. The Contractor shall perform operations using a method that will prevent the material from flowing back into the Channel or into an environmentally sensitive area on the back side, bounded approximately by Corpus Christi Ship Channel Station 340+00 and Station 360+00. No material or runoff from dredging will be allowed to enter the sensitive area. Toe levees shall be constructed as necessary to direct effluent and natural runoff toward the open back bay and away from the sensitive area. Material shall be deposited within the limiting lines of discharge shown. Material deposited beyond the limiting lines of discharge shall be removed by the Contractor at no additional cost to the Government. Operations, including moving machinery and related equipment on this Placement Area shall be performed using a method that will prevent damage to existing vegetation on the front side of the existing mounds and surrounding slopes. No work is allowed on this Placement Area during the period of March 1, 2016 through August 31, 2016.

3.4.3.1.1 Environmental Considerations for Placement Area No. 7 and No. 8

This emergent Placement Area is known as Brown Pelican Island. This Island is a significant colonial water-bird nesting site that is managed by the National Audubon Society as a bird sanctuary. This Island is a major nesting site for the Federally listed endangered brown pelican. Dredged material is used beneficially to nourish the island that is highly susceptible to land and vegetation erosion. Dredged material is deposited over the crests of existing mounds onto the surrounding slopes to enhance bird nesting. Placement operations are limited to before and after the period of March 1st, 2016, through August 31st, 2016, to avoid interruptions in nesting activity. This operation is for dredging shoaled reaches of the Corpus Christi Ship Channel while nourishing and enhancing bird habitat. It is possible that bird nesting activity may occur outside the dates specified above. Placement operations and movement of equipment are prohibited within 1,000 feet of any active nesting site, eggs or chicks.

3.4.3.2 Confined Placement Area No. 10

The weir boards shall be furnished and installed at Placement Area No.

10. The dredge pipeline routes to the Placement Areas are shown. The Contractor shall furnish and install sufficient spillway boards at each drop-outlet structure needed to raise the weir elevations to within 3 feet of top-of-levee elevations. Lumber shall be southern yellow pine rough No. 2, dense, minimum allowable bending stress of 1,400 psi. Treated lumber shall be furnished and installed by the Contractor on the sides of the structure from the top of the concrete slab or headwall to two feet below the top of the structure. The contractor shall field verify the length and width of the treated lumber for the drop outlet structure.

Lumber shall be 8-inches nominal width. Lumber shall be straight, even sawed, sound, and entirely free from defects which can impair its

SECTION 35 20 23.16 45 Page 13 durability or its usefulness for the purpose intended. Lumber shall bear the official Grade mark of the association under whose rules it is purchased or, in lieu thereof, each shipment shall be accompanied by a certificate of inspection issued by the inspection association. Lumber shall have a Chromated Copper Arsenate (CCA) preservative treatment and shall be accompanied by a certificated from a recognized treatment company certifying the amount of treatment. During Placement operations, the Contractor shall take the precautions necessary to prevent erosion of the levee. No dredge slurry shall be drained or allowed to drain over or to reach the levee. When placing material into the Placement Area, the Contractor will assure that a minimum 3 feet of freeboard continually exists above the ponded water level throughout the entire levee perimeter.

Material shall be deposited over existing mounds without overtopping or breaching the adjacent levees. Drainage shall be provided and no ponds will be allowed to form between the discharge mounds and the levee. The spillway shall be monitored daily to assure proper water quality. Contractor will inspect placement operations at the Placement Areas. Dredging operations into the Placement Areas shall cease and placement operations shall not be resumed until the containing structure has been restored to an approved condition. Damage or scouring of the levees due to the Contractor's operations, shall be repaired to the original condition at no additional cost to the Government.

3.4.3.3 Open Water Placement Area Nos. 15A and 15B

Placement Area Nos. 15A and 15B shall be prominently marked by the Contractor with conspicuous buoys at each corner. For material originating in the La Quinta Channel, the initial placement operation shall begin 5,400 from the centerline of the Corpus Christi Ship Channel. The Placement operation shall extend from the initial discharge point toward and perpendicular to the Corpus Christi Ship Channel for approximate length of 2,000 feet to the front limit of the lines of discharge. No material shall be placed outside of these limiting lines of discharge, which define the Placement Area. As the material accumulates and becomes emergent at the point of discharge, the discharge pipe shall be moved away from the Channel along the line of discharge to another point of discharge. When possible, the discharge end of the pipe shall be held at or near the bottom during placement operations to confine the material within the designated Area.

A spreader shall be used at the submerged end of the discharge pipe to distribute the material evenly and reduce scouring.
