Measurements performed, and the associated calculations, should be well documented in the project records and should be recorded to no less than the minimum specified precision of the measurement. (For example: “Measurement will be made to the nearest linear foot” means to measure to no less than the nearest linear foot.) Confirm that the tools being used to make the measurement are accurate within the range required for the measurement. Calculations may be made manually, with a calculator or a computer but in each instance the results should be independently verified to eliminate math, keystroke or computer related errors.

Specifications typically have a "Method of Measurement" clause that indicates the minimum unit of measurement and pay. Each day that a work item is reported, the total quantity of work completed or material placed that day is to be totaled and then reported to a degree of accuracy no less than what is designated in the specification. Rounding is generally not necessary. For instance, tickets for hot mix asphalt generally show the measured quantity to the nearest hundredth of a ton even though the degree of accuracy per spec is only required to be to the nearest tenth of a ton. The tickets should be totaled to the nearest hundredth and reported to that accuracy in AWP each day. The daily quantity does not need to be rounded nor does the final pay quantity at project closeout need to be rounded.

When payment is made per station, it should be assumed that the work is performed in a single pass through the project limits and that the work may be along the centerline, on either side or on both sides. For example, work on both sides of the centerline that is one station long is to be paid as one station of work, not two. This guidance is to be waived when the specifications or plans are explicitly contradictory.
