2. Structures will be measured according to neat lines indicated or as ordered in writing, unless otherwise specified. Concrete and masonry will be measured and accurately computed by dividing the work into simple geometrical figures and adding their volumes.

3. Items which are measured by the linear foot, such as guardrail, under-drains, and the like, will be measured parallel to the base or foundation upon which such structures are placed, unless otherwise indicated or specified.

4. In computing volumes of excavation, embankment or borrow, methods utilizing electronic computation, planimeters, or other accepted engineering procedures having general acceptance in the engineering profession will be used. When measurement is based on cross sectional area, average end area method will be used.

5. Allowance will not be made for surfaces laid over a greater area than those indicated, or for any material moved from outside the area of cross section and lines shown on the

Drawings except when specifically authorized by the Engineer.

August 2026 01150-2

6. The term "gauge" when used in connection with the measurement of plates, will mean the

U.S. Standard Gauge, except that when reference is made to the measurements of galvanized or aluminum sheets used in the manufacture of corrugated metal pipe, metal place culverts and arches, metal cribbing and corrugated aluminum pipe, the term "gauge" will mean that specified in AASHTO Designations M36, M167, M196, or M197.

7. When the term "gauge" refers to the measurement of wire, it will mean the wire gauge specified in AASHTO Designation M32.

8. The term "pound" when used in the measurement or payment of any material or work, will mean 16 ounces avoirdupois, based on computed or scale weight.

9. The term "ton" when used in the measurement or payment of any material or work, will mean the short ton consisting of 2,000 pounds avoirdupois. When applicable, materials measured in pounds will be converted to tons.

10. Materials that are specified for measurement by weight shall be weighed on standard scales furnished by, and at the expense of, the Contractor. Such scales shall be sealed at the expense of the Contractor as often as is necessary to insure their accuracy. A sworn weigher, to be compensated by the Contractor, shall weigh materials required to be weighed as above provided. Weighing of such materials may be witnessed by the

Engineer. If materials are shipped by rail or trucks, the car weights or quarry weights may be accepted but scales shall be used as above, if so directed. Weight slips shall be provided for each shipment of material weighed. Each weight slip shall be signed by the sworn weigher. Weight slips will be countersigned on delivery by the Engineer and no weight slip not so countersigned will be included for payment under the Contract.

11. When requested by the Contractor and approved by the Engineer in writing, material specified to be measured by the cubic yard may be weighed and such weights will be converted to cubic yards for payment purposes. Factors for conversion from weight measurement to volume measurement will be determined by the Engineer and shall be agreed to by the Contractor before such method of measurement to pay quantity is used.

12. Bituminous materials, where specified to be paid for separately, will be measured for payment by the gallon; or by the ton and then converted to gallons.

13. Bitumen delivered in tank trucks or tank feeders shall be weighed on scales, and the volume computed on the basis of a current tabulation of "Weights per Gallon of

Bituminous Materials," as approved by the Authority.

a. Provisions for weighing bitumen shall conform to the requirements of Article 1.2

D.10 above.

b. Bitumen delivered in tank cars, when not actually weighed, shall be measured by volume at loading temperature, and this quantity converted to the volume at the applying temperature. Coefficient of expansion or contraction per degree F shall be

0.00035 for asphalt, 0.00025 for asphaltic emulsions, 0.0004 for cutback asphalt, and 0.0003 for tar.

c. In no case shall the total number of gallons of bituminous material for any car be in excess of the United States Interstate Commerce Commission's rating for the car, August 2026 01150-3 plus the expansion based on the volumetric change between the loading and the specific application temperature.

d. Only the quantity of bituminous material actually placed in the Work and accepted will be considered in determining the amount due the Contractor.

14. Where specified to be paid for separately, Portland cement will be measured by the bag or barrel as indicated. A bag of cement shall contain 94 pounds net and shall be considered equal to 1 cubic foot. A barrel of cement shall weigh 376 pounds net.

15. Timber will be measured by the 1,000 feet board measure (M.F.B.M.) actually incorporated in the structure. Measurement will be based on nominal widths and thicknesses and the extreme length of each piece.

16. The term "each," when used as an item of payment, such as project markers, right-of-way monuments, and the like, will mean complete payment for the work prescribed for that item.

17. The term "lump sum," when used as an item of payment will mean complete payment for the work prescribed for that portion of the Contract work under the item, or all work prescribed in the Contract, as the case may be.

18. When a complete structure or structural unit (in effect, "lump sum" work) is specified as the unit of measurement, the unit will be construed to include all necessary fittings and accessories.

19. The Quantities may be shown on the Contract Drawings for items for which lump sum is the method of measurement. If shown, the quantities are approximate and are shown for estimating purposes only.

20. The term "complete in place," when used in the measurement and payment provisions, means the completion of the contract item, including the furnishing of all materials, equipment, tools, labor and work incidental thereto, unless otherwise specified.

21. Rental of equipment will be measured by hours of actual working time and necessary traveling time of the equipment within limits of the Contract, or between the source of supply and contract site (but not exceeding 100 miles) except when special conditions or other agreements make some other method of measurement desirable and is specified.

(Also see Article 1.4B of this Section 01150)

22. When standard manufactured items are specified such as fence, wire, plates, rolled shapes, culvert pipe, and the like, and these items are identified by gauge, unit weight, section dimensions, or other measurements, such identification will be considered to be nominal weights or dimensions. Unless more stringently controlled by tolerances in cited specifications, manufacturing tolerances established by the industries involved will be accepted.
