Costs of such repairs and downtime of the dredge and attendant plant shall be at the Contractor's expense.

3.3 DISPOSAL OF EXCAVATED MATERIAL

3.3.1 General

Maintenance material excavated from the IWW shall be transported to and deposited in the beach disposal areas as shown on the contract drawings.

The average distance of material transport to the beach disposal site from the dredging areas is 4.2 miles and the maximum distance if 5.0 miles.

3.3.2 Beach Disposal

During placement of dredged material in the beach disposal area, the Contractor will be required to provide constant radio contact between the dredge and the disposal area. This will enable the Contractor's personnel at the disposal area to immediately notify the dredge in the event of pipeline failure. In the event of pipeline failure, the dredging operations shall be immediately suspended and require prompt repair of the pipeline as a prerequisite to the resumption of dredging.

3.3.2.1 Placing of Dredged Material at Anastasia Sate Park Beach Disposal Area

Material designated in the drawings for beach disposal shall be placed on the dry beach according to the following paragraphs and formed to the template shown in the drawings. Material designated in the drawings for swash zone placement shall be released directly into the surf swash zone from a single discharge point or multiple discharge points if necessary to prevent material mounding at the point of discharge.

3.3.2.2 Order of Dry Beach Placement at Anastasia State Park and Summerhaven Beach Disposal Areas

Unless otherwise directed by the Contracting Officer, placement of material designated in the drawings for beach disposal shall commence at the northern end of the placement area and proceed south to the southern terminus of the placement area. The material shall be placed to the

SECTION 35 20 23 Page 9 Revision 0001 sections and limits shown on the drawings to the extent of the dredged material.

3.3.2.3 Swash Zone Placement at Anastasia State Park Beach Disposal Area

Release of material designated in the drawings for swash zone placement at the Anastasia State Park beach disposal area shall begin immediately south of the southern terminus of the dry beach placement area, and any additional discharge points required shall be kept as close to the original discharge point as possible.

3.3.3 Grade Stakes

Grade stakes shall be metal pipes that can be completely removed intact by the Contractor after placement of the fill. Grade stakes shall be of sufficient length to protrude above the final berm elevation and facilitate their extraction.

3.3.4 Temporary Longitudinal Dikes

Temporary longitudinal dikes and spreader and/or pocket pipe shall be used to prevent gullying and erosion of the beach and fill and to retain the fill on the beach and within the limits of the fill cross section. As the work progresses, dikes or mounds shall be constructed along the beach to direct the pipeline discharge longitudinally along the beach to avoid transverse gullying directly from the discharge point to the ocean, and to build the new berm to design grade. Longitudinal dikes shall initially be 300 feet long in advance of filling operations. They may need to be lengthened to meet water quality standards, to build to the required lines and grades, and to keep material within the toe-of-fill. The Contractor will not be held responsible for erosion caused by waves after the beach fill has been satisfactorily placed. No undrained pockets shall be left in any fill during or upon completion of the work. The Contractor shall not permit wastewater to flow landward of the fill section or water to pond between the fill and upland. Groins, bulkheads, revetments, seawater pipe structures, and other structures within the fill section shall be protected by the Contractor to prevent damage thereof by the Contractor's operations. Any damages assessed as a result of any of the above items shall be at the Contractor's expense. Temporary longitudinal dikes are not required for swash zone placement.

3.3.5 Rehandled Materials

Any material that is rehandled or moved and placed in its final position by methods other than hydraulic shall be placed in horizontal layers not exceed three (3) feet in thickness. Compaction of the layers will not be required. The Contractor shall schedule his operations to take advantage of tides so that filling is done in the dry or as directed.

3.3.6 Dressing

Final dressing shall not take place until all dredging is completed, at which time all evidence of haul road or pipeline shall be removed and the fill shall be graded and dressed so as to eliminate any undrained pockets and abrupt humps and depressions in the beach fill surfaces and as necessary to comply with subparagraph "Tolerances" below. Grade stakes used in the placement of the fill shall be removed intact, without breaking. All dikes shall be completely degraded. The bank caused by wave forces shall be graded down to a slope no steeper than 1 vertical on

SECTION 35 20 23 Page 10 Revision 0001

20 horizontal.

3.3.7 Tolerances

A tolerance of one (1.0) foot above the prescribed berm grade and slopes above the wave zone will be permitted in the final beach surface.

3.3.8 Debris Removal

Prior to placement of fill, the Contractor shall remove from the site of the work all snags, driftwood, wrack (marine vegetation), concrete rubble, reinforcement bars, and similar debris lying within the foundation limits of the beach fill section. All materials removed shall be disposed of in areas provided by and at the expense of the Contractor and approved by the Contracting Officer.

3.3.9 Pipeline Access

Pipeline access to the disposal areas is shown on the drawings. The pipeline shall not impede traffic in the marked navigation channel or navigable waters south of the southern extent of the marked channel.

3.3.9.1 Vehicular Access Across Dredge Pipeline

The Contractor shall provide access across the on-land portions of the dredge pipeline by either ramping over or burying the pipeline for a sufficient length to provide a safe vehicular crossing. Location of such access serving the Anastasia Island State Park (AISP) disposal site shall be coordinated with the Contracting Officer and ASIP personnel to provide access to all portions of the Park property affected by the pipeline location.

3.3.9.2 Access by Sea Turtle Hatchlings Across Dredge Pipeline

Upon request of ASIP Biologists, the Contractor shall elevate specific portions of the beach pipeline located seaward of active turtle nest(s) above the ground surface to a height deemed sufficient by the Biologist for the passage of sea turtle hatchlings. Affected portions of the pipeline may be buried as an alternative to elevating to provide sea turtle access upon approval of the ASIP Biologist and the Contracting Officer.

3.3.9.3 Presence of Archeologist During Excavation in Work Area

Because of the historic and cultural significance of the land where the work is located, an archeologist shall be present during any excavations by the Contractor on Park property including those required to bury the pipeline. If deemed necessary by the archeologist present, excavation shall be halted to preserve in place or recover artifacts uncovered by the excavation operation. See Section 01 57 20 ENVIRONMENTAL PROTECTION, subparagraph "Preservation and Recovery of Historic, Archeological, and Cultural Resources" for further information.

3.3.10 Dredge Pipelines

3.3.10.1 Dredge Discharge Pipeline

The Contractor shall plainly mark the pipeline access routes with conspicuous stakes, targets and/or buoys to be maintained throughout the

SECTION 35 20 23 Page 11 Revision 0001 contract operations. A tight dredge discharge pipeline shall be maintained to prevent spilling of dredged material or dredge water outside of the disposal area. The Contractor shall provide and maintain radio communication between the dredge and the disposal areas and the dredge and the Contracting Officer. The pipeline shall be inspected at least twice daily for leaks. Failure to immediately repair leaks in the discharge pipeline will result in suspension of dredging operations and require prompt repair of pipeline as a prerequisite to the resumption of dredging. Any damage to private or public property resulting from the Contractor's operations shall be repaired by the Contractor at his expense.

3.3.10.2 Submerged Pipeline

Submerged portions of the pipeline shall rest on the bottom, and the top of the submerged pipeline and any anchor securing the submerged pipeline shall be no higher than the required project depth for the channel in which the submerged pipeline is placed. Should the Contractor elect to use a pipeline material which is buoyant or semi-buoyant, such as PVC pipe or similar low density materials, the Contractor shall securely anchor the pipeline to prevent the pipeline from lifting off the bottom under any conditions. The Contractor shall make daily inspections of the submerged pipeline to ensure buoyancy has not loosened the anchors. The Contractor shall remove all anchors when the submerged pipeline is removed. The location of the entire length of submerged pipeline shall be marked with signs, buoys, lights, and flags conforming to U.S. Coast Guard regulations.

3.3.10.3 Floating Pipeline

Should the Contractor's pipeline not rest on the bottom, it will be considered a floating pipeline and shall be visible on the surface and clearly marked. In no case will the Contractor's pipeline be allowed to fluctuate between the surface and the bottom, or lie partly submerged.

Lights shall be installed on the floating pipeline as required in paragraph SIGNAL LIGHTS above. The lights shall be supported either by buoys or by temporary piling, provided by the Contractor and approved by the Contracting Officer. Where the pipeline does not cross a navigable channel, the flashing yellow all-around lights shall 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 shall govern, at no additional cost to the Government.

3.3.11 Booster Pumps

Any booster pumps installed by the Contractor shall be located at least 300 feet from any residential-type building or house. Booster pumps, their prime movers, and any auxiliary equipment shall be fitted or equipped with mufflers, noise control enclosures, or other engineering noise control methods, measures, and features such that steady noise emanating from this equipment does not exceed 85 decibels on the A scale at slow response, and impulsive noise does not exceed 140 decibels. Such items shall be maintained throughout the course of the work.

3.3.12 Misplaced Material

Material deposited above the maximum indicated elevation or outside of the disposal area template shown will require the degrading or removal of such materials at the Contractor's expense. The Contractor will not be held responsible for erosion caused by waves after the material has been satisfactorily placed.

SECTION 35 20 23 Page 12 Revision 0001

3.3.13 Beach Escarpment Elimination

The Contractor shall consider escarpment removal as part of the post-construction cleanup. Refer to Section 01 57 20 ENVIRONMENTAL PROTECTION, subparagraph "Escarpments Surveys" for further details.

3.4 REQUIRED DEPTH, ALLOWABLE OVERDEPTH, AND SIDE SLOPES

3.4.1 Required Depth

The material actually removed from the designated areas to be dredged, to a depth of not more than the required depth shown on the drawings, will be estimated and paid for in accordance with the provisions contained in the subparagraphs "Measurement" and "Payment" of Section 01 22 00 MEASUREMENT

AND PAYMENT.

3.4.2 Allowable Overdepth

To cover the inaccuracies of the dredging process, material actually removed from the designated areas to be dredged, to a depth below the required depth of not more than the allowable overdepth shown on the drawings, will be measured and paid for in accordance with the provisions contained in the subparagraphs "Measurement" and "Payment" of Section

01 22 00 MEASUREMENT AND PAYMENT.

3.4.3 Side Slopes

Although dredging of side slope material may be necessary to provide the required project channel dimensions (depth and width), the side slopes shown on the drawings are provided for payment purposes only. Side slopes may be formed by box cutting, step cutting, or dredging along the side slope. Material actually removed, within the limits approved by the Contracting Officer, to provide for final side slopes not flatter than that shown on the contract drawings, but not in excess of the amount originally lying above this limiting side slope, will be measured and paid for in accordance with the provisions contained in subparagraphs "Measurement" and "Payment" of Section 01 22 00 MEASUREMENT AND PAYMENT.

Such amount will be estimated and paid for whether dredged in original position or by box cut dredging whereby a space is dredged below the allowable side slope plane on the bottom of the slope for upslope material capable of falling into the cut. End slopes and transition slopes will not be estimated or paid for under this contract. In such cases, a 0 horizontal on 1 vertical will be used with no upslope allowance provision applied outside the required prism.

3.4.4 Excessive Dredging

It is recognized that the limits of dredging need to extend beyond the pay prism in order to remove material from within the pay prism. Therefore, the limits of active dredging may exceed the limits of the pay prism in vertical dimension as well as horizontal dimension to the extent necessary to remove material from the pay prism. Indirect impacts (sideslope sloughing, etc) may extend even beyond the limits of active dredging.

Nevertheless, material taken from beyond the limits of the pay prism as described in subparagraphs "Allowable Overdepth" and "Side Slopes" above will be deducted from the total amount dredged as excessive overdepth dredging, or excessive sideslope dredging, for which payment will not be made. Nothing herein shall be construed to prevent payment for the

SECTION 35 20 23 Page 13 Revision 0001 removal of shoals performed in accordance with the applicable provisions of the paragraphs FINAL EXAMINATION AND ACCEPTANCE or SHOALING of this Section.

3.4.5 Areas to be Dredged

Based on information currently available to the Government, areas known to require dredging are depicted on the drawings as hatched areas. The actual areas to be dredged may vary from the hatched areas shown in the drawings. In order to provide the required project dimensions within and throughout the project limits shown on the drawings, the Contractor shall remove material located within the project limits as directed by the Contracting Officer, regardless of whether the material is located in a hatched area or not. Payment for all dredged material dredged from a hatched area will be made at the applicable contract unit price. Payment for all material dredged from a non-hatched area may be made at the applicable contract unit price; however, the Contractor may request an adjustment to the contract unit price in accordance with DFAR Clause 252.243-7002 REQUESTS FOR EQUITABLE ADJUSTMENT and/or FAR Clause 52.243-4 CHANGES of Section 00700 CONTRACT CLAUSES in Volume 1.

3.5 SURVEYS

3.5.1 General

The Contracting Officer shall be notified, in writing, 10 days in advance of the need for pre-dredging and after-dredging surveys. Surveys will be performed in accordance with the paragraph QUANTITY SURVEYS of Section 00700 CONTRACT CLAUSES in Volume 1; paragraph LAYOUT OF WORK of Section 01 11 00 SUMMARY OF WORK; Section 01 45 05 DREDGING/BEACH FILL PLACEMENT -

3.5.2 Contractor Representative

The Contractor or his authorized representative will be notified when soundings and/or sweepings are to be made, and will be offered the opportunity to be on board the Government survey vessel, but may decline the offer. All in-place measurement surveys and final acceptance sweep surveys will be performed by the Government. The Contractor's representative shall be fully knowledgeable in offshore construction subsurface surveying procedures, techniques, equipment, and horizontal and vertical calibration methods, and state-of-the-art horizontal and vertical accuracy limitations. The Contractor's representative may observe and review, in progress, the adequacy and accuracy of the survey for in-place payment purposes, and for the potential existence of collusion, fraud, or obvious error in the data.

3.5.3 Survey Certification

a. Immediately upon completion of any survey, the Contractor's representative shall, based on his on-site review of the survey execution, determine that the survey contains no evidence of collusion, fraud, obvious error, and that subsequent horizontal and vertical corrections are accurately annotated on the subsurface record.

SECTION 35 20 23 Page 14 Revision 0001

b. The Contractor's authorized representative shall bring aboard the survey vessel a blank copy of the Certification Statement and shall attest to an acceptable survey by signing the Certification Statement before leaving the vessel. Sample copy of the Certification Statement is on the web site indicated in paragraph CONSTRUCTION FORMS AND DETAILS below.

c. In the event the Contractor's authorized representative observes (and quantifies) specific documentary evidence of either fraud, collusion, or obvious error, the survey will be immediately rerun.

Resurveys will totally supersede any previously run survey and will be run over the full reach of any particular Acceptance Section.

d. If acceptability is not acquired after performing one resurvey of an Acceptance Section, a meeting shall be held between the Contractor and the Contracting Officer to expeditiously resolve the issue causing rejection of the survey. Contractor equipment and personnel standby time to resolve acceptability of the survey shall be at the Contractor's expense.

e. In no case shall a previously unacceptable survey be later judged acceptable by the Contractor; unless such a reassessment/reevaluation is performed within 24 hours after the original survey, and prior to initiating any resurvey action based upon identifiable collusion, fraud, or obvious error.

f. Should the Contractor or his authorized representative refuse to certify to the acceptability of a survey for contract payment without identifiable collusion, fraud, or obvious error, then the following actions will follow:

(1) Preconstruction (pre-dredging) Survey: Excavation shall not commence until representatives of the Contractor and Contracting Officer have met and resolved the basis for refusal of certification. Should the Contractor commence excavation prior to obtaining an acceptable survey, he shall be liable for any excavation performed. If a resurvey is performed, and accepted, prior excavation will not be measured, estimated, or paid for.

(2) Post-Construction (after-dredging) Survey: The 2-week survey window allowed under subparagraph "Measurement" of Section 01 22 00 MEASUREMENT AND PAYMENT will be indefinitely extended until a final survey is accepted. Any material accretion which might occur due to such a time extension will neither be measured, estimated, or paid for.

(3) Refusal to Certify: Contractor equipment and personnel standby time to resolve his refusal to certify to the acceptability of a survey when there is no identifiable collusion, fraud, or obvious error shall be at the Contractor's expense and resultant delays shall not be the basis for time extensions of the contract.

g. Intermediate surveys taken between the pre-dredging and post-dredging surveys will not be considered for the purposes of determining quantities for final payment and acceptance of the area dredged.

SECTION 35 20 23 Page 15 Revision 0001

3.5.4 Tide Data

3.5.4.1 Real Time Kinematic (RTK) GPS

RTK GPS will be used for determining Real Time water levels (tide corrections). The Contractor is responsible for providing onboard RTK capable GPS equipment for all surveying and dredging operations.

3.5.4.2 Kinematic Tidal Datum

A file listing the separations between the Reference Ellipsoid and the Chart Datum (Mean Lower Low Water) will be provided to the Contractor for entry into the hydrographic survey software. NAVD 88 will be referenced in all new surveys and new contract documentation as related to this contract.

3.5.4.3 Non-Operational Reference Station

In the event that the reference station becomes non-operational, the Contractor shall call the point of contact indicated in the paragraph "Real Time Kinematic (RTK) GPS" above. The Government will take measures to ensure correction of any problems with the GPS equipment located at the bath house within 72 hours of notification.

3.6 QUALITY CONTROL

The Contractor shall establish and maintain quality control for operations under this section to assure compliance with contract requirements and maintain records of his quality control for materials, equipment, and construction operations, including but not limited to the following:

3.6.1 Preparatory Inspection

(To be conducted prior to commencing work.)

a. Check location of borrow area and conditions of beach areas to be filled.

b. Discuss plan of action for dredging, transporting, and placing fill on beach.

c. See that all equipment is approved and is in satisfactory working condition.

d. Check safety requirements and, particularly, public safety.

e. Check the beach site for structures that could be susceptible to damage or which could have further damage caused by the Contractor's activity.

3.6.2 Initial Inspections

(To be conducted after a representative sample of the work is complete.)

a. Check for proper lines, grades, and elevations.

b. See that diking and fill discharge is satisfactory.

SECTION 35 20 23 Page 16 Revision 0001

c. Check grades and slopes of fill placement.

d. Check finished area for proper dressing and elimination of undrained pockets and abrupt humps.

e. Check any adjacent structures to search for damage by Contractor's equipment.

3.6.3 Follow-up Inspection

(To be conducted daily to assure compliance with results of initial inspection.)

a. Check items mentioned in preparatory and initial inspection.

b. Damage or defects.

A copy of these records, as well as results of corrective action taken, shall be furnished the Government as directed by the Contracting Officer.

3.7 QUALITY CONTROL FOR BEACH PLACEMENT OF SAND

The Contractor shall perform construction observation to reasonably assure that the work will be in conformance with the required contract and permit conditions. Construction observation shall be conducted during periods of active construction.

The Contractor shall provide onsite observation by an individual with training or experience in beach nourishment and construction inspection and testing and knowledgeable of the project design and permit conditions.

The project Quality Control Plan to be implemented by the Contractor shall be discussed as a matter of importance at the pre-construction meeting.

The Contractor shall be required to acknowledge the goals and intent of the Quality Control Plan in writing.

The Contractor's daily reports shall characterize the nature of the sediments encountered at the borrow area and placed along the project shoreline with specific reference to moist sand color and the occurrence of rock, rubble, shell, silt or debris that exceeds acceptable limits.

To assure that the fill material placed on the beach is in compliance with the permit, the Contractor shall conduct assessments of the sediment as follows:

a. The Contractor's on-site personnel (site supervisor and equipment operators) shall continually visually monitor the material being placed on the beach for unacceptable material. The Government will make frequent daily visual inspections of the material being placed on the beach during periods of active construction. The material will be visually compared to the acceptable sand criteria provided in Table 1 below. If determined necessary by the Government, quantitative assessments of the sand will be conducted for grain size, shell content, and moist Munsell color. A record of each sand evaluation will be provided within the daily reports.

b. Materials which differ from the specifications provided in Table 1 will be considered unacceptable materials. Unacceptable materials

SECTION 35 20 23 Page 17 Revision 0001 also include debris, trash, and rocks or rubble larger than three-fourths (3/4) inch in diameter. Note that silt is defined as any material finer than 0.063 mm (Sieve No. 230).

Table 1 - Sediment Quality for Channel Area Material

Sediment Parameter Parameter Definition Project Compliance Value

Maximum Silt Content Passing #230 sieve 10%

Maximum Shell Content Retained on #4 sieve 5%

c. If it is determined that the grain size, moist Munsell color, shell content, or silt content do not comply with the quality requirements outlined in the Quality Control Plan, the Contractor shall immediately cease material excavation operations excavating in the area where the unsuitable material originated from and relocate excavation operations to an area shown by project geotechnical data to be free of unsuitable material and take whatever actions necessary to avoid further discharge of unsuitable material . In this event, the Government will use the dredge positioning records, plans, and vibracore descriptions to determine the area containing unacceptable materials the Contractor shall notify the Contracting Officer of the location of unsuitable material . Unacceptable material that the Contractor dredges from this area shall not be used for beach placement. The Government will provide an alternate disposal site for the unacceptable material. The Government will then determine if remediation is necessary the limits of the affected area which will not be dredged .
