DREDGING

AMENDMENT NO. 0002

PART 1 GENERAL

1.1 SUMMARY

The work in this Section consists of furnishing plant, labor, materials, and equipment to perform the operations necessary for the removal of sediment debris to the required dimensions shown, satisfactory disposal thereof, and other operations incidental thereto. The Contractor may use either a pipeline or mechanical dredge, or combination of both, in performing the work. All dredged materials must be placed in the Placement Areas designated in this Contract.

1.2 MEASUREMENT AND PAYMENT

Measurement and payment for 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 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 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. Survey data has been posted to EM Public website:

http://www.swg.usace.army.mil/Business-With-Us/Emergency-Management-Office/ 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, SECTION 35 20 23.16 45 Page 3 after having once been made will not be reopened, except on evidence of collusion, fraud, or obvious error.

iv) and the passing by other vessels of floating plant working in navigable channels as set forth in United States Coast Guard publication entitled Navigation Rules and Regulations Handbook. Web site location:

http://www.navcen.uscg.gov/?pageName=navRuleChanges

1.12 PLANT

1.12.1 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.

1.12.2 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.

1.13 INSPECTION

The Government will supervise the maintenance of the gages, ranges, location marks, and limit marks in proper order and position; but the presence of the inspector will not relieve the Contractor of responsibility for the proper execution of the work in accordance with the

SECTION 35 20 23.16 45 Page 6 specifications. The Contractor is required to furnish the following items.

1.13.1 Equipment

At the request of the Government, the Contractor will 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.

1.13.2 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.

1.14 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 major obstruction to water flow, 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 $6,731.02 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.

1.14.1 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.

1.15 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

SECTION 35 20 23.16 45 Page 7

Contracting Officer.

1.16 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. 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.

1.17 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, 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.

1.18 QUANTITY SURVEYS

1.18.1 General

Quantity surveys are to be conducted, and the data derived from these surveys are to be used in computing the quantities of work performed and the actual construction completed and in place.

1.18.2 Dredging Sections

The Government will conduct the original and final surveys and make the computations based on them. The Contractor is to conduct the surveys for the periods when progress payments are requested and make the computations based on these surveys. Surveys conducted by the Contractor will be conducted under the direction of the Contracting Officer, unless the Contracting officer waives this requirement in a specific instance.

1.18.3 Submittals

Promptly upon completing a survey, submit the originals of every field note and other record relating to the survey or to the layout of the work in accordance with the SECTION 01 33 00 SUBMITTAL PROCEDURES. The Contracting Officer will use them as necessary to determine the amount of progress payments. Retain copies of submitted material.

1.19 CONTINUITY OF WORK

No payment will be made for work done in an area designated by the

SECTION 35 20 23.16 45 Page 8

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.

PART 2 PRODUCTS

2.1 BRIDGE-TO-BRIDGE RADIOTELEPHONE EQUIPMENT

Dredge and self-propelled attendant floating plant is to be radiotelephone equipped to comply with the provisions of the Vessel Bridge-to-Bridge Radiotelephone Act (Public Law 92-63). This will require, as a minimum, the radiotelephone equipment capable of transmitting and receiving on

156.65 MHz (Channel 13). Multi-channel equipment will also require 156.8 MHz (Channel 16). Dredge tugs and tenders will be considered towing vessels within the meaning of the Act.

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 except that the Contractor is not expected to dredge virgin or stiff clay material. The work is to be done in accordance with this Contract and at the Contract price or prices, subject to the provisions of the 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 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. If virgin or stiff clay materials are encountered, the Contractor shall reduce the depth of dredging such that only sandy material is removed even if the required prism limits have not been reached and the Contracting Officer must be notified immediately.

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

SECTION 35 20 23.16 45 Page 9 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 SHOALING.

3.2 AREAS TO BE DREDGED

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

3.3 CONDUCT OF DREDGING WORK

3.3.1 Protection of Existing Waterways

Conduct dredging operations using a method that will ensure that material or other general 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 general 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.

3.3.2 Adjacent Property and Structures

No dredging will be permitted within 100 feet from the West Lake Houston bridge, unless otherwise noted or shown, and 25 feet from other structures. 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. Do not use banklines to support the dredging operation as this could negatively impact the vegetation, wildlife, or private property. Do not place equipment on shorelines unless approved by the Contracting Officer and the property owner.

SECTION 35 20 23.16 45 Page 10

3.4 PLACEMENT OF EXCAVATED MATERIAL

3.4.1 Placement Area

Two sandpit locations have been designated as placement areas for the sediment debris, Placement Area (PA)1, at or near 20550 Townsen Blvd., Humble, Texas (Lat. 30^ 01' 03.39" North, Long. 92 14 56.54" West) and Placement Area (PA)2 near 27220 Sorter Road, Porter, Texas (Lat. 30^ 02' 45.49" North, Long. 95^ 15' 45.82" West).

PA1 has a calculated capacity of approximately 230,000 CY when filled to the existing surrounding ground. PA2 has an undetermined capacity, but it is estimated that it exceeds the placement requirements.

Sediment debris excavated or dredged mechanically must be placed in PA1.

PA1 shall be filled to the surrounding existing ground elevation. After completion of placement in PA1, fill is to be graded to prevent ponding and to drain toward the San Jacinto River and adjacent waters.

3.4.2 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 should consider include, but are not limited to, the Federal Migratory Bird Treaty Act and the Endangered Species Act of 1973.

3.4.2.1 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 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 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.

3.4.2.2 Placement Operations Inspection

Adequately inspect placement operations in the Placement Area(s) daily to reduce the possibility of spillage of dredged materials outside the Area and to verify proper drainage of the effluent.

3.4.2.3 Placement Area Drainage

Trenches or culverts are to be constructed within the right-of-way to provide proper outfall for the placement areas. Contractor is to ensure deposited materials will not impede natural drainage and that at least two feet of freeboard are maintained (AM#2)except when filling the last 4 feet of PA 1. The trenches are to be of adequate number and size to drainage capacity equal or larger than the material been deposited (water plus soil) in the Placement Areas.

SECTION 35 20 23.16 45 Page 11

3.5 PRESERVATION OF PUBLIC AND PRIVATE PROPERTY

SECTION 35 20 23.16 45 Page 12

3.8.1 Submerged Pipeline Lighting Requirements

Lighted buoys, meeting the requirements of the U.S. Coast Guard Regulation 33 C.F.R. 62.25 Lateral marks, are to be provided by the Contractor to mark the navigation opening. A red buoy exhibiting a quick flashing red light is to be used to mark the right side of the opening and a black buoy exhibiting a quick flashing green light is to be used to mark the left side of the opening. The frequency of the flashes are to be not less than 60 per minute. "Right side" and "left side" of the opening is to be in conformance with the lateral system of buoyage established by the U.S.

Coast Guard. Requirements for lighted buoys and description of the lateral system of buoyage will be found in the U.S. Coast Guard Publication entitled "Aids to Navigation." Lights to be displayed on pipelines are to be in accordance with the U.S. Coast Guard Regulation 33 CFR 84 Annex 1: Positioning and Technical Details of Lights and Shapes:

http://www.ecfr.gov/cgi-bin/text-idx?SID=af0fba13c030ab68deca2ccd17a 3493a&node=pt33.1.84&rgn=div5.

3.8.2 Floating Pipeline

If the Contractor's pipeline does not rest on the bottom, it will be considered a floating pipeline and is to be visible on the surface and clearly marked. The Contractor's pipeline is not to be allowed to fluctuate between the surface and the bottom, or to lie partly submerged.

Lights are to be installed on the floating pipeline as required in the Paragraph: SIGNAL LIGHTS. The lights are to be supported either by buoys or by temporary piling, provided by the Contractor and approved by the Government. Where the pipeline does not cross a navigable channel, the flashing yellow all-around lights are to be spaced not over 200 feet apart, unless closer spacing is required by U.S. Coast Guard personnel, in which case the requirements of the U.S. Coast Guard will govern, at no additional cost to the Government. Floating pipelines are to also be in accordance with SECTION 01 35 26.01 45 GOVERNMENTAL SAFETY REQUIREMENTS.

3.8.3 Pipeline Leaks

If a leak occurs in the discharge pipeline, immediately discontinue using the line until leaks are repaired. The Contractor will be responsible for removing material placed due to leaks or breaks.

3.9 WORK IN THE VICINITY OF OTHER GOVERNMENT CONTRACTORS

Coordinate dredging operations through the Contracting Officer, with other Government Contractors who may be working in the vicinity (for example:

revetment, jetty repairs, and dike construction).

3.10 DREDGING AND DREDGE RELATED MARINE WORK (CESWG)

GOVERNMENTAL SAFETY REQUIREMENTS.

3.11 DREDGE PLANT INSTRUMENTATION

The Dredge Plant Instrumentation is a part of the dredge plant and is to be functional at all times. If failure of any part thereof occurs, repair the failed part within the next 36 hours restoring full operations. If the system is not fully functional within this period, the particular

SECTION 35 20 23.16 45 Page 13 plant affected will be considered non-responsive to this Contract requirement and is to either be replaced or a redundancy part added to render the plant fully operational to include the monitored data at no additional increase in price or time to this Contract.
