1.6QUANTITY MEASUREMENT

A.General

1.The Department uses nominal weights and dimension, and

industry-manufacturing tolerances unless otherwise specified

2.The Department measures and determines quantities of material

furnished and work performed according to the measurement and payment section of the contract.

3.The Department identifies standard manufactured items by gauge,

unit, weight, or section dimensions.

B.Plan Quantity

1.The calculated quantity in the Bidding Schedule is the quantity for

which payment will be made.

Measurement

2.An adjustment to the final quantity for payment may be made if an

error is discovered in the calculated quantity by either the Department or the Contractor.

a.Provide all computations, plots, and supporting

documentation necessary for the Engineer to verify the error and determine the final quantity for payment. 1) Work required to provide computations, plots, and supporting documentation may be paid for as new work when the final quantity differs from the calculated quantity by more than 10 percent.

b.The Engineer may adjust the final quantity for payment by

the amount of increase or decrease to the calculated quantity in the Bidding Schedule based on provided supporting documentation.

C.Lump Sum or Each

1.The Department measures the complete structure or structural unit,

signal or lighting system, or other items of work specified in the Bidding Schedule to be measured by lump sum or each to include all necessary work, fittings, and accessories for a complete unit or system.

2.“Lump sum” or “each” includes all resources necessary to

term of measurement.

E.Area

transverse measurements unless otherwise specified.

F.Volume

1.The Department measures items using plan (neat) dimensions, or

altered dimensions when approved by the Engineer to fit field conditions.

2.The Department uses average end area or computer generated

Digital Terrain Model (DTM) method for computing volumes.

3.Materials specified to be measured by volume may be converted to

unit weight for payment purposes when approved.

a.Obtain approval for all factors for conversion from volume to

weight before using this method of measurement.

Measurement

G.Weight

1.The term “ton” means 2,000 pounds avoirdupois.

2.Measure aggregate weight in the saturated surface dry condition.

H.Alternative methods of measurement

1.Refer to Section 01721.

1.7WEIGHING REQUIREMENTS AND PROCEDURES

A.Weigh all materials that are measured or proportioned by weight, or

contract items measured by the ton, such as aggregates and asphalt materials, on scales that have been approved, certified, and that meet specification requirements.

1.Obtain certified haul truck tares at times as determined by the

Engineer and place a legible identification mark on each truck.

2.The Department may return to be reweighed any loads that appear

to be deficient or questionable.

B.Furnish, erect, certify, and maintain, or use permanently installed and

certified commercial scales for weighing highway and bridge construction materials that are required to be proportioned or measured and paid for by weight.

1.Scales must be accurate within the limits set by the laws of the

State of Utah and meet requirements of the U.S. Bureau of Standards.

2.Scales must bear a current seal of acceptance from the State of

Utah Department of Agriculture, Division of Weights and Measures.

3.Have the Utah State Department of Agriculture Division of Weights

and Measures inspect and seal all scales at least once a year and after each setup before use, or as requested by the Engineer.

4.Install and maintain platform scales with rigid bulkheads at each

end. The platform must be level.

a.Platform scales must be of adequate size and capacity so

the entire power unit and hauling unit can be weighed at the same time.

5.Physically arrange electronic, beam, dials, platform, and other scale

equipment for convenient and safe viewing by the operator and inspector.
