The Contractor shall dredge no deeper than the maximum elevation shown on the plans for each area of the borrow area. The location of unsuitable material encountered within the borrow area shall be noted on the Contractor's Quality Control Report (copy appended to the end of Section 01 45 05 DREDGING/BEACH FILL PLACEMENT - CONTRACTOR QUALITY CONTROL). If the Contracting Officer determines the quality of beach fill is being adversely affected, that location shall be avoided in future passes of the dredge.

GROUP-10-R-J0009 SECTION 35 20 25 Page 6 Revision 0003

3.2.2 Magnetic Anomalies

A magnetometer survey was conducted in the borrow site. No magnetic anomalies were encountered.

3.2.3 Turbidity

Excavation and filling operations shall be done in a manner that will minimize turbidity of the water at the excavation site and at the discharge from the fill area. If monitoring shows turbidity exceeds the background at the compliance stations as specified in Section 01 57 25 TURBIDITY AND DISPOSAL MONITORING, all construction activities shall cease immediately and not resume until corrective measures have been taken and turbidity has returned to acceptable levels.

3.2.4 Dredge Location Control

The Contractor is required to have electronic positioning equipment that shall locate the dredge when operating on the project. This equipment shall include real-time measurement of the water (tide) level. The Contractor is required to calibrate the equipment as required by the manufacturer or as required by the Contracting Officer. Proof of calibration shall be submitted to the Contracting Officer. Continuous locations of the dredge shall be made at all times during dredging and transporting operations. The reason the dredge is outside the borrow area limits shall be annotated on the position chart and on the Contractor's Quality Control Report for each occurrence. The location of the dredge is to be by computed coordinates with a probable range error not to exceed plus/minus 3.0 feet and furnished daily as part of the dredge reports, along with a real-time drawing of the track of the dredge in relation to the borrow area. The Contractor's method of location of the dredge shall be submitted for review. A Differential Global Positioning System (DGPS) or equivalent shall be used; LORAN-C shall not be permitted for location control. The Contractor is also required to have a depth of dredging indicator for each dragarm accurate to within plus/minus 0.5 feet. The instrument used shall indicate the depth of dredging at all times and draghead depth when the dredge is outside the borrow area limits. For hopper dredges, the instrument may be a graph type paper or electronic recorder or an indicator which uses a pointer and scale. The reported elevation of dragarm and/or dredging shall be adjusted by the measured water level elevation and shall be reported relative to the datum indicated on the drawings (MLW) and shall have a probable range error not to exceed plus/minus 0.5 feet vertical. The paper or depth record produced by this instrument shall be submitted daily with the daily dredge report. The reason the dredge is outside the borrow area limits shall be annotated on the depth record and the draghead depth shall be highlighted. Flagging or marking the winch cables are not an acceptable option to fulfill this instrument requirement. The indicators shall be in plain view of drag tenders, quality control and Government inspectors.

3.2.5 Submerged and Floating Pipeline

3.2.5.1 Submerged Pipeline

In the event the Contractor elects to submerge his pipeline, 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 project depth for any navigation channel in which the submerged pipeline is placed. Should the Contractor elect to use a pipeline material which is

GROUP-10-R-J0009 SECTION 35 20 25 Page 7 Revision 0003 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. Pipeline corridors over hardbottom areas have been identified in the plans. The Contractor shall not relocate these corridors. No pipelines are to be placed on hardgrounds.

3.2.5.2 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.

3.2.6 Deduction for Nonconforming Work

Beach fill that is obtained from unauthorized areas will not be paid for under this contract. Excavation in such area(s) is a violation of State of Florida Permits and the Bureau of Ocean Energy Management (BOEM) agreement for this work. The Government will perform pre-dredge and after-dredge surveys in the borrow areas. If it is determined that dredging has been performed outside the borrow area(s) or below the limiting elevation plus a 2-foot buffer within the borrow area(s), the quantity of the material dredged from these areas will be computed and subtracted directly from the pay quantity of material placed on the beach.

3.3 TRANSPORT OF EXCAVATED MATERIALS

The method of transporting the fill from the offshore borrow area(s) to the fill area shall be by hopper dredge or barge with pump-out capabilities.

3.3.1 Hopper Dredge

Overflow at the borrow site during loading will be permitted to the extent that turbidity and water quality standards required by Section 01 57 20 ENVIRONMENTAL PROTECTION are met. The Contractor shall limit the loading to partial loads, if necessary, to meet turbidity and water quality requirements permitted at the borrow site. No overflow or spillout will be permitted during transport to the discharge site. Failure to repair leaks or change method of operations which result in spillage that exceeds turbidity and water quality standards during loading or any overflow during transport to the discharge site will require suspension of dredging operation. The prevention of overflow or spillage shall be a prerequisite to the resumption of dredging. The Contractor shall provide and maintain barricades, warning signals, and flagmen to insure public safety in the vicinity of the pipe pumpout operations. Any damages to private or public property resulting from the Contractor's operations shall be repaired by

GROUP-10-R-J0009 SECTION 35 20 25 Page 8 Revision 0003 the Contractor at his expense.

3.3.2 Work Area

The Contractor shall inventory all anchors, buoys, and buoy cables deployed in the prosecution of the work in a manner acceptable to the Contracting Officer. The Contractor shall use this information to account for and recover these items at the completion of the project.

3.4 BEACH FILL

3.4.1 General

All beach fill sand excavated from the borrow area shall be transported to and deposited on the beach within the lines, grades, and cross section shown on the drawings except as may be modified by the provisions of subparagraph b. of subparagraph "Construction" below. Except as specified in subparagraph "Dressing for Payment" below, the Contractor shall maintain and protect the fill in a satisfactory condition at all times until acceptance of the work. Any fill sand which is lost in transit or permitted to flow into the offshore waters or onto the upland from the point the sand is discharged on the beach will not be subject to payment.

The fill shall be free of clay lenses, rock or silt pockets. Any such material remaining in the fill shall be removed and disposed of by the Contractor as approved by the Contracting Officer. Any existing signs, buoys or other structures within the work lines shall be protected and/or removed and later replaced by the Contractor as directed. The Contractor shall provide sand ramp walkways across the beach pipeline at intervals not greater than 300 feet to correspond to the locations of existing public beach access walkways.

3.4.2 Construction

a. Prior to placement of fill, the Contractor shall remove from the site of the work all snags, driftwood, 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. Grading and other construction equipment will not be permitted outside the easement lines shown on the drawings except for designated ingress and egress to and from the site. Mobile equipment of any type operating within 50 feet of any seawall, building, groins, or other structure as determined by the Contracting Officer shall be rubber wheeled. Tracked equipment shall not be permitted to operate within 50 feet of any seawall, building, groin, or other structure as determined by the Contracting Officer. Hand tools may be required in these areas.

b. The excavated material shall be placed and brought to rest on the beach to the lines, grades, and cross section indicated on the drawings, unless otherwise provided for herein or directed by the Contracting Officer. The Contractor shall not stockpile pipe or any other equipment or debris on private property which is west (landward) of the Erosion Control Line as shown on the drawings. Pipe shall be placed parallel to shore and landward as far as possible without compromising the dune system. See SECTION 01 57 20 ENVIRONMENTAL PROTECTION for additional requirements. The beach is subject to changes and the elevations on the beach at the time the work is done may vary from the elevations shown on the drawings. The Contracting Officer reserves the right to vary the width and grade of the berm from

GROUP-10-R-J0009 SECTION 35 20 25 Page 9 Revision 0003 the lines and grades shown on the plans in order to establish a uniform beach for the entire length of the project. The beach fill cross sections shown on the drawings are for the purpose of estimating the theoretical amount of fill needed and will be used by the Contracting Officer in making any change in the lines and grades. The Contractor will not be required to dress the fill below the mean high water to the slopes shown but will be required to do the dressing specified in subparagraph "Dressing for Payment" below.

c. Construction staking on the beach shall be made of steel pipe or other material that can and will be removed intact after filling as verified during final walk-through inspection. The Contractor shall inventory all the construction staking used on the project in a manner acceptable to the Contracting Officer.

d. The Contractor shall maintain a tight discharge pipeline for the pumpout operations at all times. The joints shall be so constructed as to preclude spillage and leakage. The pipeline corridor shall be visually inspected by the Contractor daily during period of active pumpout operations for signs of slicks, plumes, boils, or other surface anomalies that would indicate leaks, seepage, ruptures, or failures.

All occurrences shall be indicated in the Contractor's QCR. The development of a leak shall be promptly repaired or the pumpout operations shall be shut down until complete repair has been made to the satisfaction of the Contracting Officer. The Contractor shall be required to maintain barricades, warning signals, and flagmen to insure public safety in the vicinity of the pipe discharge. Any damages to private or public property resulting from the Contractor's operations shall be repaired by the Contractor at his expense.

e. Grade stakes and any other stakes for any purpose shall be made of steel pipe that can and will be removed intact after filling to cross sections accepted by or as directed by the Contracting Officer.

All stakes shall have sufficient length above grade so they may not be accidentally covered by fill. The Contractor shall consecutively number each piece of pipe used for grade stakes, shall clearly mark that number upon the pipe, and shall record the location of each numbered pipe in a grade stake log. The removal of each numbered pipe shall be recorded in the grade stake log at the time of the pipe/stake removal. At the request of the Contracting Officer, all of the grade stake pipes shall be displayed after their removal to demonstrate those pipes that have been removed. All pipes used for grade stakes placed within the limits of the beach fill work shall be numbered and shall be recorded in the log. It is the Contractor's responsibility to track, locate, and completely remove all grade stakes in their entirety to the satisfaction of the Contracting Officer.

f. Temporary longitudinal dikes and spreader 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 as necessary 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 500 feet long in advance of filling operations. They may need to be lengthened to meet water quality standards. Shorter lengths may be subsequently used if approved by the Contracting Officer but not less than 300 feet. More than one series of longitudinal dikes may be required to meet water

GROUP-10-R-J0009 SECTION 35 20 25 Page 10 Revision 0003 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 and accepted. 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, piers, dune walkovers, 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.

g. Mechanical operations may be needed to place material to the required lines and grades. The Contractor shall address the placement methods(s) in the Work Plan. Stockpiling, additional longitudinal dikes, and/or other special handling may be needed. It is the Contractor's responsibility to place material to the specified lines and grades within the fill crossed section.

h. 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 exceeding three (3) feet in thickness. Compaction of the layers will not be required. The Contractor shall schedule his operations to take advantage of the tide so that filling is done in the dry or as directed.

3.4.3 Dressing for Payment

Immediately following placement of the new beach fill the Contractor shall grade, level and dress the beach fill to meet the required elevations and dimensions indicated on the drawings. The dressing for payment shall include the removal of humps, depressions, undrained pockets, excavated material at locations of swales for drainage culverts, and vehicle access ramps, etc., prior to final pay survey being taken of an area of Acceptance Section.

3.4.4 Dressing for Final Acceptance

Immediately upon the completion of beach fill placement and removal of equipment and materials from the beach fill area, the final dressing shall be accomplished by the Contractor for final acceptance. This final dressing is a requirement as part of the post-construction cleanup and prior to the sand compaction measurements required by Section 01 57 20 ENVIRONMENTAL PROTECTION of the contract. The bank caused by wave forces shall be graded down to slope not steeper than 1 vertical to 10 horizontal. Grade stakes shall be removed intact and any excavation required to remove the stakes shall be backfilled.

3.4.5 Tolerances

Final grade (F.G.) shall be within tolerances of minus five-tenths (0.5) of a foot of or on the beach fill grade line. (Refer to Beach Fill Tolerance figure on the web site indicated in paragraph CONSTRUCTION FORMS AND DETAILS below noting that there is no plus tolerance.) Tolerance shall extend entire berm and slope to intersection of slope and pre-construction surveyed condition. Contractor may stockpile beach fill above the the beach fill grade line up-slope of the slough zone, to compensate for material expected to be removed by wave action; but smooth slopes shall be

GROUP-10-R-J0009 SECTION 35 20 25 Page 11 Revision 0003 maintained. Berm width will vary as directed by the Contracting Officer.

Slope shaping shall be accomplished by grading fill into water or as directed by the Contracting Officer. Some parts of the existing beach are above the proposed grade. In these areas the Contractor shall not reshape or degrade the existing beach to meet the proposed grade.

3.4.6 Misplaced Materials

If any material is deposited other than in places designated or approved, the Contractor may be required to remove such misplaced material and redeposit it where directed at his expense.

3.4.7 Work Area

The construction easements and borrow area limits available to the Contractor for accomplishing the work are shown on the drawings. At the fill site, the Contractor may only operate within the work areas shown on the drawings. No anchoring shall occur within 150 feet of the hardbottom areas except within the pipeline corridor. The Contractor shall exclude the public from the work areas in the immediate vicinity of his dredging, transporting, and disposal operations. The Contractor shall prevent public access to the discharge end of his pipeline. The Contractor shall erect, maintain, and move as necessary, a restrictive barrier around the discharge of the hydraulic pipeline used for beach disposal; i.e., similar or equal to orange polypropylene geogrid safety fencing. The barrier shall be constructed so as to prevent the public from approaching the discharge from any direction closer than 40 feet. The Contractor shall post signs in a conspicuous manner stating "DANGER - HIGH PRESSURE DISCHARGE FROM DREDGE".

Enforcement shall be the Contractor's responsibility at no additional cost to the Government. The enforcement shall be coordinated with local enforcement agencies, and will be subject to approval of the Contracting Officer. Construction access is provided as shown on the drawings.

Procurement of additional access routes for ingress and egress to the construction area shall be obtained by and at the expense of the Contractor. Additionally, the Contractor shall place a safety person at the discharge end of the disposal pipeline. The safety person shall be present at all times during discharge operations and will maintain radio communication between the dredge and the disposal operation.

3.4.8 Construction Access

Construction access is provided as shown on the contract drawings.

Procurement of additional access routes for ingress and egress to the construction area shall be obtained by and at the expense of the Contractor and shall be approved by the Contracting Officer. At all access sites to be utilized, the Contractor shall:

a. Photo-document the condition of the access location prior to disrupting the site.

b. Limit access width through existing vegetation to 20 feet or less.

c. Replace any fencing, signage or curbing disturbed by the Contractor's activities; and,

d. Restore and revegetate the access route with native dune plants subject to the approval of the Contracting Officer. Revegetation of access and staging areas shall be with sod (non-dune areas) or viable plant units (dune areas) at 18-inch maximum spacing with species and

GROUP-10-R-J0009 SECTION 35 20 25 Page 12 Revision 0003 diversity equivalent to preconstruction conditions. Revegetation shall include a survival warranty of 90 percent of the plant material for 90 days. Vegetation shall be installed with fertilization and irrigation, or with initial irrigation, fertilization and approved water-absorbent polymeric gels, at no additional expense to the Government. Shrubs and trees shall be replaced to preconstruction conditions per the requirements of Section 01 57 20 ENVIRONMENTAL PROTECTION.
