QUANTITY MEASUREMENT TERMS

Measurement under the contract shall be according to the United States standard measure.

The methods of measurement and computation will be those necessary to accurately determine the quantities of materials furnished and work performed. Measurement will be made of each item or unit of work, as shown in the Schedule of Items, completed and accepted in accordance with the contract provisions, specifications, and drawing.

1. All items which are measured by the linear foot, will be measured parallel to its longitudinal centerline, unless otherwise shown on the drawings.

2. A station when used as a definition of term or measurement will be 100 linear feet

3. Miles will, in the absence of known distances from existing plans or surveys, be determined by the Government using a calibrated survey odometer or equal substitute operated on the traveled way at or parallel to road centerline.

4. The term "ton" will mean the short ton consisting of 2,000 pounds avoirdupois. Trucks used to haul material measured by truck weight shall be weighed empty at least once daily, and each truck shall bear a plainly legible identification mark. Weigh tickets furnished by the

Contractor from certified scales will be used to determine weight measurements.

5. Materials measured by the cubic yard in the hauling vehicle shall be measured therein at the point of delivery. Vehicles may be of any size or type, provided that the box is of such shape that the actual volume may be readily and accurately determined.

6. Measurement by the acre will use the length and width treated. Measurement of width will approximate significant slope breaks, but will not include minor deviations along the slopes.

The measured slope distance for width will be multiplied by the length treated and converted to a standard 43,560 square foot acreage value of the surface area treated.

7. Volume of bituminous products will be measured at 60° F, using ASTM D-1250 for asphalts except the quantity of emulsified asphalt will be determined by measuring the emulsified asphalt at a temperature of 60° F, or by converting the gallonage measured at another temperature to gallonage at 60° F by means of the following formula:

Gallons. at 60° F = Gallons at A° F

1+0.00025 (A° F − 60° F)

In which A° F is the temperature of the material at the time the gallonage is measured.

8. The term "lump sum" when used in the Schedule of Items will mean the complete unit as required by or described in the contract.
