SECTION 01 22 00.00 10 Page 2

0010.

All Stone will be measured for payment by the ton as determined by barge/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 prior to weighing any stone. The scales shall be capable of printing a weight ticket including time, date, truck number, and weight. If commercial scales are readily available in close proximity (within 10 miles) of site of work, documentation shall be submitted certifying that the scales meet the requirements of the specification. Furnish the scales and weigh the stone in the presence of the Contracting Officer,. 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. Scales will be checked and certified before hauling stone and after each 50,000 tons increment of stone weighed under this contract.

b. Barge or vessel Load

(1) If delivered by barge or vessel, stone will be measured for payment by the Contracting Officer by weight determined by barge/vessel displacement. Furnish the Contracting Officer a barge/vessel displacement table not less than 10 work days prior to unloading the stone from any barge/vessel. Each table submitted shall show the name and/or number of the barge/vessel 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 vessel displacement tables a drawing or sketch of each barge/vessel, dimensioned in sufficient detail to permit checking of the tables. The drawings shall show, as a minimum, the length, width, depth of the barge/vessel, 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/vessel in feet and tenths from zero to the full depth of the barge/vessel and the corresponding gross displacement to the nearest ton. Each barge/vessel shall be suitably marked with two displacement gaging locations on each side near each end of the barge/vessel and two amidships on opposite sides. Each gaging location shall be marked by a line perpendicular to the edge of the barge/vessel, 4 inches wide and 1 foot long, on both the deck and side of the barge/vesseland two amid ship on opposite sides. BargesVessels with rakes shall have the displacement gaging lines placed at each corner of the box section between the rakes. If a barge/vessel 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 four gaging locations and the displacement determined by the use of "STANDARD BARGE/VESSEL TABLES" from the

SECTION 01 22 00.00 10 Page 3 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. BargesVessels 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 + 2xG4 + 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/vessel until after the final readings have been taken.

(2) If barge/vessel tables are furnished for fresh water and if it is believed that barge/vessel displacement measurements made within the contract limits of the work are being taken in water that has salinity, the Contractor has the option of obtaining water samples and determining densities or unit weights of these samples. These water samples shall be taken in accordance with ASTM D3370 (Practice A - Grab Samples) at depths of 4 and 8 feet in the area where measurements are made. Water sampling shall be performed when the bargesvessels are measured for quantities, both when fully loaded and when empty. Take water samples, as witnessed by the Contracting Officer, with the use of "Polypro" 2000 ml water sampler, or equal. Densities shall be determined as specified in ASTM D1429 (Method D-Hydrometer Method). Testing shall be done for the Contractor by a certified testing laboratory, and test results certified by the laboratory. After review and approval of the test results by the Contracting Officer, the average of the densities obtained at 4 and 8 feet will be used as the suitable salt water conversion factor. In all calculations, the unit weight of 62.4 pounds per cubic foot will be used for fresh water.

c. Stockpiled Stone . If the Contractor elects to stockpile stone on the worksite or offsite, the stone shall be weighed immediately before placement by either method described above. Stone placed in temporary storage on the worksite as specified section 35 31 19 STONE MATERIALS AND PLACEMENT paragraph WORKSITE STOCKPILE will not be required to be re-weighed prior to placement. If the barge/vessel displacement method is elected, a minimum of one-third the total maximum displacement of the barge/vessel tons of stone is required on each bargevessel.

d. Determination of Excess Stone. All stone outside the limits and tolerances of the cross sections of the structure, except variations so minor as not to be measurable, will be deducted from the quantity of new stone for which payment is to be made. Weight of excess stone will be determined from the cross sections obtained by the method provided

SECTION 01 22 00.00 10 Page 4 for in paragraph FINAL SURVEYS, on the basis that the cubic feet of volume (including voids) for each type of stone, as listed in the Table in section 35 31 19 STONE MATERIALS AND PLACEMENT paragraph FACTORS USED FOR CONVERTING IN PLACE VOLUME TO WEIGHT, is equal to one ton or 2,000 pounds for the bulk specific gravity and percentage of voids shown. If the bulk specific gravity of the stone furnished or the percentage of voids is other than as listed below, the cubic feet of volume equaling 2,000 pounds shall be recomputed. Should any excess stone be disclosed above the tolerance line as defined in paragraph TOLERANCES, its volume will be computed by the average end area method, based upon the cross section in the following manner. The average end area of excess stone above the tolerance line for two (2) successive cross sections, multiplied by the distance between the cross sections will be accepted as the volume. In addition to the above, stone, which has been delivered to the site and has been lost or wasted or otherwise not properly incorporated into the final required work, shall be deducted from the quantity for which payment is to be made.

e. Final Surveys. Survey work and measurements required for determination of excess volume computations for stone materials shall be performed in the presence of the Contracting Officer. Notify the Contracting Officer not less than 3 days in advance of each survey. In the event of unavailability of the Contracting Officer, perform the survey and certify to the Contracting Officer that it complies with the specifications. Cross section surveys shall be taken perpendicular to the axis of the structures. Elevations and soundings shall be taken on lines 25 feet apart measuring along the structure reference line, with the readings at 5-foot intervals and at breaks in the grade along the line. Other survey intervals and readings may be used if deemed appropriate or advisable by the Government's on-site representative.

Additional cross sections, elevations, and soundings may be taken if determined necessary by the Government's on-site representative.

Determination of quantities will be made by the Government's on-site representative and having once been made, will not reopen, except on evidence of collusion, fraud or obvious error. Prior to performing any work under this Section, coordinate all operations with the Government's on-site representative so that excess volume surveys will be made at the appropriate time. The surveys made under section 35 31 19 STONE MATERIALS AND PLACEMENT paragraph CHECK SURVEYS may be used when deemed appropriate by the Government's on-site representative, as part of the surveys required herein. Stone quantity computations shall be based entirely upon weights of new stone as determined from carrier displacement or certified scale weight tickets. Existing stone placed in lieu of new stone from off-site sources is excluded from measurement and payment.
