Before reef pad material is produced from a source for completion of the work, the source of reef pad material shall be approved by the Contracting Officer. Approval of a reef pad material source shall not be construed as a waiver of the right of the Government to require the Contractor to furnish reef pad material that complies as specified herein. Materials produced from localized areas, zones, or strata will be rejected when these materials do not comply as specified herein.

a. Source Documentation: Authorization of proposed reef pad material source will be based on prior test results and service records. The Contracting Officer may elect to use either past USACE test results or a combination of service records along with USACE approved test results from other agencies or private laboratories. A service record is considered acceptable if reef pad material from the proposed source has remained sound and functional after at least 10 years of exposure on a project similar to the one to be constructed under this contract.

b. Acceptance of Materials: During the contract period, both prior to and after materials are delivered to the job site, visual inspections and measurements of the reef pad material may be performed by the Contracting Officer. If the Contracting Officer, during the inspections, finds that the reef pad material quality, gradation or weights of reef pad material being furnished are not as specified or are questionable, re-sampling and re-testing by the Contractor shall be required. Sampling of the delivered reef pad material for re-testing and the manner in which the re-testing is to be performed shall be as directed by the Contracting Officer. This additional sampling and testing shall be performed at the Contractor's expense when test results indicate that the materials do not meet specified requirements. Any material rejected shall be removed or disposed of as specified and at the Contractor's expense.

1.6.3 Quality Testing

Contractor's quality assurance testing shall be performed by a qualified testing laboratory meeting the requirements of ASTM D3740 and ASTM E329, and qualified by USACE Materials Testing Center (MTC). At least 15 calendar days in advance of shipment of reef pad material to the work site, a copy of quality test results shall be furnished. Samples to be tested shall be selected by the Contractor, unless otherwise directed by the Government if present. The Government reserves the right to perform independent testing. Costs for this additional sampling and testing shall be at the Contractor's expense.

At least one set of quality tests shall be performed of reef pad material.

Periodic tests for specific gravity and gradation shall be performed by the Contractor for each 10,000 cubic yards of reef pad material shipped. Not less than 3 sets of specific gravity and gradation tests shall be performed for each reef pad material type. Sampling of the reef pad material shall be performed in accordance with ASTM D75/D75M and ASTM C702/C702M.

1.6.4 Gradation Testing

Perform a gradation test or tests on the reef pad material at the quarry.

Notify the Contracting Officer not less than 3 days in advance of each

SECTION 35 32 16.10 45 Page 4 test. At least one gradation test(s) shall be performed per 10,000 cubic yards of each size for each reef pad material type placed, but not less than 3 tests shall be performed for each reef pad material type. At least 15 calendar days in advance of shipment of reef pad material to the work site, a copy of initial gradation test results shall be furnished.

1.6.5 Quarry Operations

Conduct quarry operations in a manner to produce stone conforming to the requirements specified; this may involve selective quarrying, handling, processing, blending, and loading as necessary.

1.6.6 Daily Records

Contractor's daily activity reports shall include barge displacement measurements and associated calculations as documentation of the volume and/or tonnage of reef pad material placed each day. This information shall be provided for use by Contracting Officer and shall not serve as the basis for payment.

1.6.6.1 Barge Placement Measurements

The barge shall be gaged at an approved protected location near the site.

For this purpose each barge shall be fitted by the Contractor at its expense, with gages graduated either to inches or tenths of a foot, located either inside or outside of the hull as directed and attached solidly to the hull itself. These gages shall be located two near each end of the vessel on opposite sides and two additional gages amid ship if deemed necessary by the Contracting Officer. If located inside the hull, provision shall be made for the free passage of the outside water to a transparent tube placed or capable of being placed, in contact with the gage. If located outside upon wooden hulls, the gages shall be protected by solid fenders or recessed into the planking, or if upon steel hulls, the gage marks may be placed directly on the plates and identified by punch marks. Gages shall be placed so that their zeros are below water when the vessel is in its normal trim, light, and free from water. In lieu of the gages in the interior of the barge, the Contractor may at its discretion, provide an equal number of wells for determining the amount of the load.

These wells shall be located as specified for interior gages and shall be constructed as approved.

1.6.6.2 Fore and Aft Displacements

Fore and aft displacements, due to load, shall not differ more than 10 percent from their mean for the determination of tonnage of each barge load of stone ready for placement. In determining the tonnage of a cargo, the change in gage readings due to discharge of the cargo shall be used.

1.6.6.3 Barge Displacement Tables

The barges shall be fitted for the work sufficiently ahead of the time fixed for commencement to enable the Contracting Officer to measure them accurately before beginning work. The Contractor shall at its expense place barges in dry dock for measurement and furnish materials and facilities for taking the necessary measurements for preparing barge displacement tables. The Contractor shall pump the water from the barges when so requested but no pumping of a barge shall be done between the time it is gaged loaded and light to determine the amount of barge load.

SECTION 35 32 16.10 45 Page 5

1.6.6.4 Repairs and Additions

Repairs and additions made to the barges during the progress of the work shall be promptly reported to the Contracting Officer. During the progress of the work, when the Contracting Officer deems it advisable or necessary, each barge shall be re-measured at the expense of the Contractor and under the supervision of the Contracting Officer. No barge shall be used which is not in a seaworthy condition or which leaks excessively. The barges used shall be so constructed that when loaded they do not bend or warp so that the gages are unreliable. Each barge load shall contain only one type of material.

1.6.6.5 Determination of Weights

The gages shall be read in calm water conditions which will allow accurate determination of weights. Locations of the gage readings shall be approved in advance. To determine the load, measurements will be taken immediately before a barge starts for its point of unloading and immediately after it returns from that point. The gages will be read by the Contracting Officer and the Contractor is invited to be present when the readings are taken.

Disagreements on the part of the Contractor as to the weight of material will be submitted in writing within 10 days of their occurrence. To ensure the use of the proper weight of surrounding water in calculating the weight of material from the barge gage readings, hydrometer measurements will be made along side each barge when it is gaged loaded and light. Other methods of measurement may be used when approved.
