No separate payment will be made for stripping, excavation, backfilling, compactions and disposal of materials required for placement of stone protection and the costs in connection therewith will be included in the Contract unit price.

1.3.2.2 Measurement

Riprap placement is to be measured in short tons (2,000 pounds) using any of the following methods, which are more fully discussed in Appendix C of EM 1110-2-2302. The Contractor may use other methods of measurement conditioned on the Government's approval.

Where the loss of material resulting from stockpiling, re-handling, or its transportation is possibly significant, re-measurement prior to placement may be directed.

a) Measurement by Weighing Railcar and Truck Loads. Certified railroad car or truck weights measured on appropriate scales, before and after loading or before and after unloading will be accepted as the tonnage of stone placed in the finished section(s). From this weight, rejected stone will be deducted accordingly. The weight of the rejected stone will be estimated by the Government, or if the Contractor elects, the stone may be weighed. Stone is to be weighed on standard scales whose calibration has been certified by a Weighmaster. Each scale used shall be tested in the presence of a Government inspector at any time directed. Promptly after a railcar or truck has been weighed, and before the stone is placed, provide the original printed scale ticket or certified copy. The certified scale ticket must show the gross, tare, and net weights. Explain any changes on a report in writing, attach the explanation to the report, and have the Weighmaster sign it. The Government may employ an inspector at the scales

SECTION 01 22 00.10 Page 4 to observe the weighing. In this event, provide the necessary facilities for the Inspector to observe the weighing and recording of the scale weights and stenciled light weights on the railcars or trucks. The Contractor is responsible for the expenses incurred to weigh the stone.

Determine the weights of sideboards, stakes, and skips by actual weighing or by estimating using a method the Contracting Officer's Representative accepts. The weights so determined, together with the tare weight of the car or truck, shall be deducted from the gross weight to determine the net weight of stone delivered.

b) Measurement by Barge Load. Barge displacement measurements will be accepted for determining the weight of stone placed in the finished section(s). Provide the Contracting Officer a barge displacement table not less than 10 work days prior to unloading the riprap from any barge. Each table submitted shall show the name and/or number of the barge owner, the name of the fabricator, and the certification and date of certification of the person or firm that prepared the table. Provide with the displacement tables a drawing or sketch of each barge, dimensioned in sufficient detail to permit checking of the tables. The drawings must show, as a minimum, the length, width, depth of the barge and the dimensions of the rake or rakes. Each table shall have its accuracy certified by a person or firm, other than the Contractor, customarily performing this service. Each table submitted shall contain, in parallel columns, the barge freeboard in feet and tenths from zero to the full depth of the barge and the corresponding gross displacement to the nearest ton.

For the purpose of weighing the stone, fit each barge (at the Contractor's expense) with gages graduated in tenths of a foot increments. Locate the gages either on the inside or outside of the hull, as may be directed, and attach them solidly to the hull. Install the gages at each corner of the barge near the lower end of the rake and install two additional gages, if directed, amidship on each side. If the gages are located inside the hull, provide for the free passage of outside water to a transparent tube placed, or capable of being placed, in contact with the gage. If located outside the hull, the gages shall be protected by solid fenders or recessed into the planking, if the hull is wooden, or placed directly on the plates of a steel hull and identified with punch marks. Install the gages such that the zero mark is below water when the carrier lies in its normal trim, is light, and free from water. Do this installation when the barge is staged in a protected area near the site where approved. The Contractor may, at its option, provide an equal number of wells for determining the load instead of gages on the inside of the barge. Locate the wells as specified for the interior gages and install in an approved manner.

Fit the barges with the gages sufficiently ahead of commencing the work.

Notify the Contracting Officer a minimum of 5 days prior to the planned gage installation date to give the Government an opportunity to have an inspector present. When taking measurements, the barges must be dry-docked (at the Contractor's expense). Provide the materials and facilities necessary for taking the measurements to prepare the barge displacement tables. Pump the water from the barges when directed. Do not pump water between the time it is gage-loaded and lightened when weighing the barge load.

Fore and aft displacements due to the load must not differ more than 10 percent from their mean when determining the tonnage of each barge load of stone ready for placement. In determining the cargo tonnage, use the change in gage readings after the cargo has been offloaded.

SECTION 01 22 00.10 Page 5

Promptly report any repairs or additions made to the barges during the progress of the work. The Government may elect to have a barge re-measured at the Contractor's expense. If so, this shall be done under the observance of the Contracting Officer's Representative. No barge shall be employed that is not seaworthy or that leaks excessively to render gauging difficult. The barges used shall be so constructed that when loaded they do not bend or warp to where the gages can become unreliable. Each barge load shall contain only one class of stone.

When weighing the load, take measurements immediately before a barge starts for its point of unloading and immediately upon its return from that point. A Government inspector will record the gage readings, at which time the Contractor can be present. Any disagreement on the Contractor's part concerning the measured stone weight must be reported in writing to the Contracting Officer's Representative within 10 calendar days of the occurrence. Disputes will be handled in accordance with the CONTRACT CLAUSE entitled DISPUTES. To make sure the proper density of the surrounding water is used in calculating the weight of stone from the barge gage readings, the Government will take hydrometer measurements alongside each barge when it is empty, fully loaded, and empty again.

1.3.2.3 Unit of Measure

Unit of measure: Ton.

1.3.3 Geotextile

1.3.3.1 Payment

Payment will be made at the Contract unit price for "Geotextile - Station 0+00 to Station 201+06", in Schedule No. 1, (AM#1)and "Geotextile - Station 0+00 to Station 7+00", in Option No. 1, which will constitute full compensation for providing plant, labor, material, and equipment and performing the operations necessary for the complete and satisfactory installation of the geotextile. No payment will be made for geotextile replaced because of contamination or damage due to the Contractor's fault or negligence.

1.3.3.2 Measurement

Measurement for geotextile installed shall be in Square Yards of the as-built surface area covered by getotextile. No allowance will be made for waste, overlaps, damaged materials, repairs or material used for the convenience of the contractor.

PART 1 GENERAL

1.1 SUMMARY

The work covered by this Section consists of providing the equipment and labor and performing the operations necessary to remove existing shoreline erosion protection system(stone protection) from the project limits (AM#1) (including Option No.1, if awarded) as shown and as specified in this section. Incidental to this work is shaping the affected slopes and preparing the excavated surfaces to receive geotextile, reused (reusable) stone and new stone as shown. Excavation work does not include the filling or backfilling of areas and voids below the prescribed lines and grades to obtain the final shoreline erosion protection systemtemplates shown.

1.2 MEASUREMENT AND PAYMENT

Excavation to remove the existing stone protection from project limits (AM#1)(including Option No.1, if awarded) and for incidental preparation of the slopes accordingly to build new semi-compacted berm and receive the new stone as shown and specified will be measured and paid for as stated in

SECTION 01 22 00.10 MEASUREMENT AND PAYMENT.

1.3 SHORELINE EROSION PROTECTION SYSTEM ALIGNMENTS

1.3.1 Physical Alignment Layouts

Prior to commencing any construction activities, physically lay out in the field the alignments shown by staking them.

1.3.2 Changes to Alignment

The Contracting Officer may make adjustments to the new shoreline erosion protection system alignment and to the position of the stone templates relative to the baselines shown as he or she deems necessary before or during the progress of the work. The intent in making any such adjustment would be to make the design stone templates better correspond with the existing field conditions. Any moderate adjustments made will be implicit and incidental to the required excavation work. If the stone protection alignment or position is changed, the Contractor will be appropriately compensated for any additional excavation quantity that could result. No additional payment will be made however to make modest adjustments directed by the Contracting Officer. Any disagreement concerning the consequences of directed changes to the alignment or position of the prescribed stone templates will be resolved in accordance with the CONTRACT CLAUSE entitled

DISPUTES.

1.4 PROTECTION OF EXISTING SERVICE LINES AND UTILITIES

Affected existing utility lines which are made known to the Contractor prior to excavation must be protected from damage during excavation and filling. Immediately report to the Contracting Officer damage to existing

SECTION 31 23 16.19 45 Page 2 utility lines that are not shown or that the Contractor was not otherwise made aware of. If it is determined that the Contractor is to make the repairs, they will be ordered in accordance with the CONTRACT CLAUSE entitled CHANGES or DAMAGES TO WORK, whichever applies.

1.5 GRADE TOLERANCE

Excavation of the embankment slope shall be within tolerances of 3 inches above and 6 inches below the neat lines shown, as measured perpendicular to line. Where areas are below the lines and grades shown and where over-excavation is done to remove the existing stone, the areas are to be filled and backfilled withsatisfactory materials as specified in SECTION 35 41 00.01 45 - SEMI-COMPACTED BERM CONSTRUCTION . No payment will be made for backfilling areas excavated below the the specified tolerance unless the excavation was otherwise necessary to remove unsuitable soil or existing stone, as expressly allowed in this Contract, with the Contracting Officer's prior approval.

1.6 STOCKPILING OF MATERIALS

The temporary stockpiling of excavated materials adjacent to the work will be allowed where accepted. No additional payment will be made for such stockpiling or for the handling of the stockpiled material.

PART 2 PRODUCTS (Not Used)

PART 3 EXECUTION

3.1 EXCAVATION

3.1.1 General

Excavation to remove the existing stone is to be done to repair the shoreline erosion protection system shown. Over-excavation below the defined lines and grades will not be allowed except in those instances necessary to remove unsatisfactory material or stone as warranted or directed. Existing stone that may still be present below the prescribed grades is to be removed in its entirety. The filling of areas below the prescribed grades and backfilling of over-excavated areas necessary to achieve the lines and grades of the design stone templates shown is to be accomplished using satisfactory materials as specified in SECTION 35 41 00.01 45 - SEMI-COMPACTED BERM CONSTRUCTION. The intent of the excavation is to provide firm and relatively smooth surfaces upon which the geotextile can be laid and the reused (reusable)stone and new graded riprap can be placed.

3.1.2 Conduct of Work

Roughly excavate to the prescribed lines and grades. Remove any existing stone below these lines and grades and any material unsuitable to provide a firm foundation for the new stone. Do not advance the excavation so far ahead of protecting the slope with the new stone that the excavated slope

SECTION 31 23 16.19 45 Page 3 will be exposed for a protracted length of time as this will result in severe erosion damage due to wave attack and sheet flows. Discussion of how the Contractor plans on executing the work to reasonably limit the amount of erosion damage to completed excavations shall be included in the Work Plan. During the progress of the work, the Contracting Officer may direct the Contractor to change the conduct of its operations if severe erosion of completed excavations is occurring. If such changes are directed, the additional costs the Contractor incurs in adjusting its operations are to be borne by the Contractor because it will be the Contractor's responsibility to maintain a completed section of the excavation until its acceptance.

3.1.3 Foundation Preparation

Make sure that all stone below the the excavation line has been entirely removed. Shape and grade the excavated surfaces to the extent practicable to conform to the grades shown or as required below the grades shown to provide relatively smooth surfaces, including transition surfaces, upon which to lay the geotextile, reused (reusable) stone and new graded riprap. Maintain the completed section until its acceptance. Once accepted, immediately install the geotextile and place the reused (reusable) stone and new graded riprapas specified in SECTION 35 31 19.32 45

RIPRAP

3.2 DISPOSAL OF EXCAVATED MATERIALS

3.2.1 Stone

Dispose removed stone in accordance with the provisions of SECTION

35 31 19.32 45 RIPRAP.

3.2.2 Excess Soil and Organic Materials

Dispose excess excavated material that cannot be used elsewhere in the work and that does not contain appreciable amounts of stone, and unsatisfactory organic materials within the designated Disposal Area for Excess Excavated Materials located within PA 11. Alternatively, these materials may be disposed at a location off site at the Contractor's discretion. Material disposed of within the designated disposal area shall be deposited in an approved manner.

3.2.3 Inert Materials other than Removed Stone

Remove and dispose off site inert materials such as the existing geotextile underlayment and certain types of trash. Do not put debris within the placement areas or leave debris at the worksites.

3.2.4 Temporary Stockpiling

The temporary stockpiling of excavated materials will be allowed on site where approved. Temporary stockpiles must be maintained in relatively neat condition with provision for providing a safe working environment.

Routinely collect from the work areas debris encountered during initial clearing and accumulated debris up until final acceptance and properly dispose it in an approved landfill.

3.3 EROSION AND SLIDES

If erosion or sliding of any part of the excavated slopes occurs during

SECTION 31 23 16.19 45 Page 4 their construction or after their completion, but prior to their acceptance, promptly notify the Contracting Officer. Do not re-establish/restore the affected area(s), unless the Contracting Officer directs otherwise. If the slide resulted because the Contractor did not reasonably protect the completed slope against erosion and slides, was not timely in notifying the Government that an excavated area had been completed, was otherwise negligent in its responsibility to reasonably maintain the completed excavation, or because of the Contractor's construction activities, the additional quantity of stone that will have to be placed to build the prescribed shoreline erosion protection system templates will be at the Contractor's expense. The additional quantity of stone placed will be deducted from the total quantity of stone placed when computing the payment for this item. If the erosion or slide was not caused by the Contractor's operations or conduct or the Contractor's reasonable efforts to protect against these occurrences, the additional tonnage of stone that will have to be placed will be paid for as specified.

1.6 SYSTEM DESCRIPTION

Factors Used for Converting In-Place Volume to Weights

The following factors were used in converting the in-place volume to the quantities shown in the BID SCHEDULE.

Bulk Stone Material Bulk Specific Gravity

(SSD)

Percent Voids

Cubic Feet of Volume per Ton, including Compensation Voids (for Excess Quantity Calculations)

Graded Riprap 2.65 28 16.80

Reused Stone 2.65 31 17.53

1.6.1 Revision of Bid Schedule Quantities

The estimated stone quantities given in the BID SCHEDULE were computed based on stone having a bulk specific gravity (saturated surface dry (SSD) basis) relative to water having a unit weight of 62.4 pounds per cubic foot and percentage of voids as shown in the above table. When the bulk specific gravity (SSD) of the stone to be used in the work is other than that shown in the above table, the estimated quantities will be revised by multiplying them by the fraction which results when the bulk specific gravity (SSD) of the stone furnished is divided by the value shown in the table for each respective stone gradation. Revision for the percentage of voids will likewise be made. The Contracting Officer will issue a modification to the Contract in accordance with the Contract Clause:

CHANGES to adjust the estimated quantities in the BID SCHEDULE. The revised quantities will then be the quantities from which the allowable fifteen percent (15%) variation in estimated quantity, for payment purposes, will be determined as defined in CONTRACT CLAUSE entitled

VARIATIONS IN ESTIMATED QUANTITY.

1.6.2 Re-revision of Estimated Quantities

If during the progress of the work it is determined that the stone actually placed has a bulk specific gravity range or percentage of voids different from that on which the quantities in the BID SCHEDULE are based, the BID SCHEDULE will be further revised in accordance with Subparagraph: Revision of Bid Schedule Quantities.
