109.01 Measuring Quantities

To measure completed work, the Engineer will use the United States customary measure or International System of Units (SI), as specified in the contract. The units of the two systems are not equal and are not interchangeable within a contract.

The Engineer will determine quantities of materials the Contractor furnishes and the work the Contractor performs using measurement methods and computations conforming to sound engineering practice.

The Engineer will measure actual quantities of work completed as described in the measurement subsections for individual pay items. The Agency will make payment based on these actual measured quantities. Accept estimated quantities designated in the contract to be used as final payment quantities for final payment, unless revised by approved change order.

The Engineer will measure completed work as follows:

A.   Lump Sum or Each. Consider “lump sum” or “each” payment as full compensation for all resources necessary to complete the work.

B.   Length. The Engineer will measure items paid by the linear foot (meter) or inch (millimeter) along the finished surface of the item.

C.   Area. The Engineer will use horizontal longitudinal and plan (neat) transverse measurements for surface area computations. The Engineer will not deduct individual fixtures having an area of 10 ft2 (1 m2) or less.

D.   Volume. The Engineer will measure structures using plan (neat) or approved change order dimensions.

The Engineer will use the average end area method to compute excavation volumes.

For material specified for measurement by volume in the vehicle, haul the material in vehicles approved by the Engineer. The Engineer will measure materials at the point of delivery. Ensure the body shape of the vehicle allows contents to be accurately and readily measured. Load and level vehicles to their water level capacity.

If the contract allows, the Engineer may weigh materials and convert the mass to volume using specified conversion factors.

The Engineer will measure water to the nearest 250 gallons (1000 liters) with calibrated tanks, distributors, or water meters.

The Engineer will measure bituminous materials by the gallon or ton (liter or megagram).

The Engineer will measure volumes at 60°F (16°C), or will correct volumes to the volume at 60°F (16°C) according to ASTM D 1250 or ASTM D 633.


Guide Specifications for Highway Construction
The Engineer will use net certified scale weights, or weights based on certified rail car volumes, as a basis for measurement. The Engineer will correct for bituminous material lost, wasted, or otherwise not incorporated in the work.

When bituminous materials are shipped by truck or transport, the Engineer will correct net certified weights or volumes for loss or foaming when computing quantities.

The Engineer will measure timber by the thousand feet board measure (cubic meter), based on nominal widths and thicknesses and individual maximum lengths.

E. Weight (Mass). The Engineer will use certified scales to determine weight (mass).

The Engineer may accept certified “car weights” for material shipped by rail, except for material to be subsequently processed in mixing plants.

Obtain certified haul truck tares as specified. Ensure that each haul truck displays a legible identification mark.

The Engineer will measure cement by the pound or ton (kilogram or megagram).

The Engineer will accept nominal weight (mass) or dimensions for standard manufactured items unless otherwise specified. The Engineer will accept industry-established manufacturing tolerances, unless otherwise specified.

The Engineer will measure aggregate weight (mass) in the saturated surface dry condition.

Furnish, erect, and maintain weigh systems tested and certified by ____________

(contracting Agency to complete), or use certified permanently installed commercial scales. Provide certifications after each setup and before use or as requested by the Engineer. Seal the weigh system after certification and display certification stamp. Ensure weigh systems are accurate to within ±0.05 percent of the correct weight throughout the range of use.

Provide uniformly graduated scale intervals not to exceed 0.001 times the nominal rated scale capacity, or 1 lb (0.5 kg), whichever is less. Use only mechanical or electronic scales.

Arrange beams, dials, platforms, and other scale equipment for safe and convenient viewing by the operator and inspector.

Maintain 10 standard 50-lb weights (22.5-kg masses) or other approved devices to test scales.

Service and test scales for accuracy before use at a new site. Install and maintain platform scales with the platform level and with rigid bulkheads at each end.

Correct quantities of materials received on scales found to be outside of specified tolerances based on the last documented test within specified tolerances.
