Current through Register Vol. XLI, No. 28, July 12, 2024
11.1.
				Measurement of Quantities. All work completed under the contract will be
				measured by the engineer according to United States standard measure.
11.1.a. The method of measurement and
				computations to be used in determination of quantities of materials furnished
				and of work performed under the contract will be those methods generally
				recognized as conforming to good engineering practice.
11.1.b. Unless otherwise indicated, the
				requirements prescribed hereinafter shall govern.
11.1.c. Earthwork will be computed by the
				average end area method, using the horizontal length measured along the
				centerline as the distance between sections, applying corrections for curvature
				where the apparent error exceeds 25 percent of the volume in any one cut. Other
				acceptable methods may be used.
11.1.d. Unless otherwise specified,
				longitudinal measurements for area computations will be made horizontally and
				no deductions will be made for individual fixtures having an area of nine
				square feet or less. Unless otherwise specified, transverse measurements for
				area computations will be the neat dimensions shown on the plans or ordered in
				writing by the engineer.
11.1.e.
				Structures will be measured according to neat lines shown on the plans or as
				altered to fit field conditions.
11.1.f. All items which are measured by the
				linear foot, such as pipe culverts, guardrail, underdrains, etc., will be
				measured parallel to the base or foundations upon which such structures are
				placed. The term "gage," when used in connection with the measurements of
				plates, will mean the U. S. Standard Gage.
11.1.g. The galvanized sheet thicknesses to
				be used in the manufacture of metal cribbing, corrugated iron or steel culvert
				pipe, underdrain pipe, plate pipe, pipe arches, plate pipe arches and plate
				arches shall be as specified in AASHTO M 36 or AASHTO M 167.
11.1.h. The sheet thicknesses to be used in
				the manufacture of corrugated aluminum alloy culvert pipe, underdrain pipe,
				plate pipe, pipe arches, plate pipe arches and plate arches shall be as
				specified in AASHTO M 196 or AASHTO M 219.
11.1.i. The "size number" used in the
				measurement of wire will be as specified in AASHTO M 32 or AASHTO M
				225.
11.1.j. The term ton will mean
				the short ton consisting of 2,000 lb. All materials which are measured or
				proportioned by weight shall be weighed on approved scales by competent,
				qualified personnel. Scales for weighing shall be of either the beam type,
				springless-dial type or digital recorder type.
11.1.k. All plant and truck scales and
				metering devices shall be inspected, approved and sealed in accordance with the
				requirements of the West Virginia Division of Labor, Bureau of Weights and
				Measures, or other appropriate agencies of the state or its political
				subdivisions. Poises shall be designed to be locked in any position to prevent
				unauthorized changes. When the beam type scales are used, provisions for a
				"telltale" dial shall be made for indicating to the operator that the required
				load in the weighing hopper is being approached. A device on the weighing beams
				shall clearly indicate the critical position.
11.1.l. Truck scales shall be provided by the
				producer or contractor, except that truck scales are not required where the
				material is weighed at properly calibrated automatic batching plant facilities
				which are equipped with digital print-out equipment. The scales shall be of
				sufficient size and capacity to weigh the heaviest loaded trucks that are used
				for delivery of the material. All truck scales shall be mounted on solid
				foundations which will ensure their remaining plumb and level.
11.1.m. A weigh person shall be provided by
				the producer. The weigh person shall certify that the weight of the material,
				as determined either by the truck scales or from the digital print-out of the
				weights, is correct. To signify the certification of weight the weigh person
				must either sign their full name on each ticket, or if the ticket printer
				prints the weigh person's full name, they must at least initial each
				ticket.
11.1.n. Each truck shall be
				weighed empty prior to each load, except at automatic batch plants approved to
				operate without truck scales. A digital recorder shall be required on all truck
				scales. The digital recorder shall produce a printed record of the gross, tare
				and net weights, and the time, date, truck identification and project number.
				Provision shall be made for constant zero compensation and further provision
				shall be made so that the scales may not be manually manipulated during the
				printing process. The system shall be interlocked so as to allow printing only
				when the scale has come to rest.
11.1.o. In case of a breakdown of the
				automatic equipment, the engineer may permit manual operation for a reasonable
				time, normally not to exceed 48 hours, while the equipment is being
				repaired.
11.1.p. If material is
				shipped by rail, the car weight may be accepted provided the actual weight of
				material only will be paid for. However, car weights will not be acceptable for
				material to be passed through mixing plants.
11.1.q. Devices used to meter or measure
				component or other materials in a simultaneous manner shall be located so as to
				be readily accessible and visible to a single inspector, unless otherwise
				directed by the engineer.
11.1.r.
				Materials to be measured by volume in the hauling vehicle shall be hauled in
				approved vehicles and measured at the point of delivery. Vehicles for this
				purpose may be of any size or type acceptable to the engineer, provided that
				the body is of such shape that the actual contents may be readily and
				accurately determined. All vehicles shall be loaded to at least their water
				level capacity, and all loads shall be leveled when the vehicles arrive at the
				point of delivery.
11.1.s. When
				approved by the engineer, material specified to be measured by the cubic yard
				(meter) may be weighed and these weights converted to cubic yard (meter)s for
				payment purposes. Further, when it is impractical to measure the material by
				weighing, or in its original position, the material will be measured in its
				final position and adjusted by a volume change factor. These conversion factors
				will be determined by the engineer and shall be agreed to by the contractor
				before these methods of measurement are used.
11.1.t. When bituminous material is measured
				by volume, the measured volume at loading temperature shall be converted to
				volume at 60° F (15° C) using the temperature correction factors in 705
				for asphaltic materials and 706 for tar materials, except that when volume is
				measured by an approved temperature compensated metering device, no further
				volume correction for temperature shall be required. When bituminous material
				is measured by weight, the actual specific gravity, API gravity, or weight per
				gallon (liter) of the material shall be used to convert the measured weight to
				volume at 60° F (15° C). The contractor shall furnish all information
				necessary as determined solely by the division to determine the amount of
				bituminous material actually incorporated into the project.
11.1.u. Net certified scale weights or
				weights based on certified volumes in the case of rail shipments will be used
				as a basis of measurement, subject to correction when bituminous material has
				been lost from the car or the distributor, wasted, or otherwise not
				incorporated in the work.
11.1.v.
				When bituminous materials are shipped by truck or transport, net certified
				weights or volume, subject to correction for loss or foaming may be used for
				computing quantities.
11.1.w.
				Cement will be measured by the cwt (hundredweight = 100 lb) (kilogram). For the
				purpose of determining the total amount used in the mixture, one bag of cement
				shall be considered as weighing 0.94 cwt (42.64 kg), and one barrel of cement
				shall be considered as weighing 3.76 cwt (175.55 kg).
11.1.x. Timber will be measured by the
				thousand feet board measure (mfbm) (cubic meters) actually incorporated in the
				structure. Measurement will be based on nominal widths and thicknesses and the
				extreme length of each piece.
11.1.y. The term "lump sum" when used as an
				item of payment will mean complete payment for the work described in the
				contract.
11.1.z. 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.
11.1.aa.
				When standard manufactured items are specified such as fence, wire, plates,
				rolled shapes, pipe conduit, etc., and these items are identified by gage, unit
				weight, section dimensions, etc., 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.
