Filler stone shall not measured for payment, filler stone is considered as an incidental item to cover stone. Quantities will be computed to the nearest whole ton. Stone will be measured for payment, in the presence of the Contracting Officer or authorized representative, by weighing on approved, accurately calibrated scales furnished by and at the expense of the Contractor. The scales shall be capable of printing a weight ticket including time, date, truck number, and weight. Weight certificates furnished by a public weighmaster will be acceptable. Submit Weigh Scale Certification and Certified Weight Scale Tickets, by a copy of the certification from the regulation agency, attesting to the scale's accuracy and a copy of each certified weight scale ticket after 7 working day(s) after weighing.

Stone will be measured for payment by the ton as determined by barge or vessel displacement, certified railroad weights, where direct placement into structure(s) is practicable, or by weighing by the truckload on approved scales meeting the requirements of paragraph TRUCKLOAD.

a. Truckload. Each truck load will be weighed to the nearest 0.1 ton and the final quantity rounded to the nearest whole ton. Stone will be measured for payment by weighing on approved scales before being placed in the work. Scales shall be of sufficient length to permit simultaneous weighing of all axle loads and shall have an accuracy within 0.2 percent throughout the range of the scales. The scale's accuracy shall conform to the applicable requirements of NIST HB 44 and shall be certified by an acceptable scales company representative by an inspector of the State Inspection Bureau charged with scales inspection within the state in which the project is located prior to weighing any stone. The scales shall be capable of printing a weight ticket including time, date, truck number, and weight. The Contracting Officer may elect to accept certified railroad weights or weight certificates furnished by a public weighmaster in lieu of scale weights at the jobsite. Quarry weights will not be accepted. Scales will be checked and certified before hauling stone and after each 50,000 tons increment of stone weighed under this contract.

b. Barge Load

SECTION 01 22 00.10 Page 5

(1) If delivered by barge, stone will be measured for payment by the Contracting Officer by weight determined by barge displacement.

All measurements for determing gauging tables and for calculating loads are to be made in still water close to the work site. The gauging table shall be based upon 62.4 lb/cf in fresh water and 64 lb/cf in salt water. Furnish the Contracting Officer a barge displacement table not less than 10 work days prior to unloading the stone 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 preparing the table. Furnish with the barge displacement tables a drawing or sketch of each barge, dimensioned in sufficient detail to permit checking of the tables. The drawings shall show, as a minimum, the length, width, depth of the barge, and dimensions of the rake or rakes. Each such 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 freeboard of the barge in feet and tenths from zero to the full depth of the barge and the corresponding gross displacement to the nearest ton. Each barge shall be suitably marked with three displacement gaging locations on each side near each end of the barge and two amidships on opposite sides. Each gaging location shall be marked by a line perpendicular to the edge of the barge, 4 inches wide and 1 foot long, on both the deck and side of the bargeand two amid ship on opposite sides. Barges with rakes shall have the displacement gaging lines placed at each corner of the box section between the rakes. If a barge has a box end or ends, the gaging locations shall be placed approximately 4 feet from the box end(s). The freeboard will be measured at the six gaging locations and the displacement determined by the use of "STANDARD BARGE TABLES" from the average of these measurements. The displacement will be determined before and after being unloaded and the difference between these values shall be the quantity delivered. Submit the Gaging Table Data, stone hauling vessel, gaging tables and a copy of the data and calculations used for the preparation of the tables. Barges shall be loaded so that the readings taken at the gaging locations do not vary more than 1.5 feet port to starboard fore and aft and do not vary more than 0.5 feet port to starboard. If such is not the case, trim the carrier by shifting the stone until this limit is reached, before the measurement will be accepted. The draft shall be determined from the average of all six readings weighting the readings of the middle gage at double those of the end gages. (G1 + G2 + 2xG3 + 2xG

4 + G5 + G6) divided by 8 = average draft. All carriers used in transporting stone shall be free of leaks such as would render accurate gauging difficult. Facilities for inspecting the hold of each carrier to determine whether leakage is occurring shall be provided. Each carrier shall also be provided with adequate pumping facilities, and if water is found to be accumulating in the hold, the carrier shall be pumped dry before each gaging, both before and after unloading. Lightening by pumping or by transfer of crew or supplies will not be permitted while stone is being transferred. Rejected stone and unacceptable material shall be left aboard the barge until after the final readings have been taken.

Field and Laboratory tests to which the material may be subjected are listed in the paragraph titled REFERENCES. The COR may waive the requirement for laboratory testing of stone, based on the results of visual inspections and service records in projects similar to this project. Under no circumstances will the Contractor be allowed a Contract extension for the time necessary to evaluate materials for acceptability.

1.5.1.5.1 Sources

a. Selection of Source. Designate in writing only one source or one combination of sources from which he proposes to furnish stone. It is the Contractor's responsibility to determine that the stone source or combination of sources selected is capable of providing the quality, quantities and gradation needed and at the rate needed to maintain the scheduled progress of the work. Samples for acceptance testing shall be provided in accordance with paragraph EVALUATION TESTING below. If a source for stone so designated by the Contractor is not accepted for use by the Contracting Officer, the Contractor may not propose other sources but shall furnish the stone from a source listed at the end of this Section with no additional payment.

c. Acceptance of Materials. Acceptance of a source of stone is not to be

SECTION 35 31 19 Page 8 construed as acceptance of all material from that source. The right is reserved to reject materials from certain localized areas, zones, strata, or channels, when such materials are unsuitable for stone as determined by the Contracting Officer. The Contracting Officer also reserves the right to reject individual units of produced specified materials in stockpiles at the quarry, all transfer points, and at the project construction site when such materials are determined to be unsuitable. During the course of the work, the stone may be tested by the Government, if the Contracting Officer determines that testing is necessary. If such tests are determined necessary, the testing will be done in the Government's testing laboratory or commercial laboratory selected by the Government. Materials produced from a listed or unlisted source shall meet all the requirements herein. The cost of testing will be at the Government's expense. During the contract period, both prior to and after materials are delivered to the job site, visual inspections and measurements of the stone materials may be performed by the Contracting Officer. If the Contracting Officer, during the inspections, finds that the stone quality, gradation or weights of stone being furnished are not as specified or are questionable, re-sampling and re-testing is required. Sampling of the delivered stone for testing and the manner in which the 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. When test results indicate that materials meet specified requirements, an equitable adjustment in the contract price will be made for the sampling and testing. Any material rejected shall be removed or disposed of as specified and at the Contractor's expense.

1.5.1.5.2 Pre Production Reference Stones

Before selecting a source for preparation of Pre-Production Reference Stones, the Contractor shall be reasonably certain that the source is capable of meeting the quality, quantity and source requirements specified in PART 2 - PRODUCTS below.

1.5.1.5.3 Inspection and Field Tests

At the quarry and project site, visual inspections shall be made of each Stone randomly by a SMC inspector. The visual inspections shall check size, gradation, elongation, fractures, deterioration and other defects to assure that handling during loading, transporting, unloading and placement has not caused damage to the materials and to assure they are placed in accordance with the requirements of this Section. Weighing of stones or re-measuring them shall be performed to verify computed weights when the COR brings the size of specific stones into question or the SMC inspector observes the need to do so. Except as allowed by gradation tolerances, any material broken, cracked, out of gradation or weight limitation or improperly placed in the work shall be removed and replaced with satisfactory stones and corrective action taken at no additional expense to the Government. Rejected material shall be promptly removed from the project site. Such materials are excluded from measurement for payment.

1.5.1.5.4 Random Sampling

The stone produced by each source maybe sampled by the Government for Quality Assurance testing on the basis of a maximum once each year. The samples will be evaluated based upon petrographic analysis, specific gravity, unit weight, and absorption, or such tests as determined necessary by the COR.
