AMENDMENT NO. 0003
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 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 shall include the costs for maintenance of levees, drop outlet structures 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. (AM#3)The latest surveys available are on http://www.swg.usace.army.mil/Missions/Navigation/HydrographicSurveys/GalvestonTexasCityH Note the survey data is referenced to Mean Low Tide (MLT) datum. To convert to Mean Lower Low Water (MLLW) datum for this data set, subtract
1.25 from the MLT elevations; i.e., (Elevation in MLT) - 1.25 = (Elevation in MLLW). 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
SECTION 35 20 23.16 45 Page 3 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.
1.3.2 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 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.
1.4 REFERENCES
The publications listed below form a part of this specification to the extent referenced. The publications are referred to within the text by the basic designation only.

SD-06 Test Reports
SECTION 35 20 23.16 45 Page 4
Magnetometer Survey Report; G
Report shall be submitted as specified.
1.6 CHARACTER OF MATERIAL
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. 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 Barbours Cut Channel
Barbours Cut was deepened and the channel centerline shifted to the north by 75 feet in September 2015. The cross sections shown on the drawings include the after-dredge surveys from that contract. This is the first maintenance contract on Barbours Cut since the channel improvements. Prior to the channel improvements, portions of Barbours Cut were excavated as deep as Elevation -56 MLLW.
1.6.2 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. The Government has no knowledge of existing wrecks, wreckage, or other material of that size or character as to require the use of explosives or special or additional plant for its economical removal. 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
No permits or easements are necessary for laying shore pipe at Alexander Island Placement Area or for using the site.
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:

(AM#2)The Contractor shall begin by dredging Sections 5 and 6 in any order, followed by Sections 3 and 4, and finally Sections 1 and 2.
Options 1 and 2, if exercised, shall be dredged after completing the work in Schedule No. 1. The Government reserves the right to change the order of work at any time and will do so by written modification under the CONTRACT CLAUSE entitled CHANGES. Multiple dredges shall not be used concurrently on this contract.
1.9.1 Dredging Options
If exercised, the Government will award Dredging Options as specified in
SECTION 01 10 00.01 45 NON-REGULATED SPECIAL CONTRACT REQUIREMENTS,
Paragraph COMMENCEMENT, PROSECUTION AND COMPLETION OF WORK.
1.10 NON-FEDERAL DREDGING
During the performance of this contract, other entities may request the Contractor to perform dredging at their facilities. Dredging at these facilities may be allowed provided the Contractor can demonstrate that it is on or ahead of schedule with the work under this contract. The Contractor shall provide a written request to the Contracting Officer identifying which facility it proposes to dredge, the estimated yardage, and the beginning and ending dates of the proposed non-federal dredging.
The request shall include a copy of all necessary permits for dredging and if federal placement areas are to be used, include copies of licenses required for use of those placement areas. The Contractor shall include a proposed revised schedule with its request. If the Contractor does perform non-federal dredging during the course of this contract, the Contractor will not be allowed to place material from a non-federal facility and a federal channel into the same placement area simultaneously. The Contractor shall bear the cost of removing additional shoals that occur while away from the jobsite.

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.

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. It is the Contractor's responsibility to contact Houston Vessel Traffic Service (VTS) at (AM#2)281-464-4837 to coordinate and schedule this meeting. Contractor shall 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 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
No dredging will be permitted within 25 feet of a structure. 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. 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. (AM#3)The Contractor shall choose its pipeline route such that the pipeline does not prevent vessels from entering or leaving facilities along the channel.
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
SECTION 35 20 23.16 45 Page 11 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.
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.
3.4.1.3 (AM#2)DELETED
3.4.1.4 Maintenance of Existing Levees and Drop-outlet Structures
It is the Contractor's responsibility 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 potential for failure or overtopping during ponding. Continually monitor the levee's condition and maintain the levees in a condition and at an elevation equal to or better than the condition and elevation of the levees as of the date of Contract award. Temporary access from the existing roadway to each drop-outlet structure shall also be provided. In addition, monitor the drop-outlet structures to prevent the buildup of dredge material at the weir so that the stoplogs can be removed to drain the placement area during and after disposal operations. Remove any material that accumulates at the weir that hinders the handling of the stoplogs or obstructs drainage.
3.4.2 Spillway Operations
(AM#2)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. (AM#2)
3.4.3 (AM#2)Site Management
The Contractor shall perform Site Management operations for a period of 30 calendar days after placement operations are complete at Alexander Island Placement Area. During the period, the boards on the drop-outlet structures shall be removed at a proper rate to allow drainage of the Area. Water quality standards specified in SECTION O1 45 01.00 QUALITY CONTROL shall continue to be maintained. Daily water quality tests shall continue to be taken and submitted on the Contractor's daily quality control reports. During this period, the Contractor shall not allow deposited materials to impound water or impede natural drainage. The Contractor shall, if necessary, excavate and maintain ditches to drain low
SECTION 35 20 23.16 45 Page 12 areas in the Placement Area to the drop-outlet structures (exception: the Contractor is not required to drain existing depressions such as previous borrow sites that were not filled with dredged material.) The ditches shall be of adequate number and size to eliminate ponding of water within the limits of the Placement Area.
