PWL Pay was developed at Clemson University under contract from the Federal Highway Administration Western Federal Lands Highway Division (FHWA-WFLHD). James L. Burati, Jr. was the principal investigator and provided all technical guidance. Thomas P. McAfee, Jr. performed the computer programming for PWL Pay. Bruce E. Wasill was the technical representative for FHWA-WFLHD.
PWL Pay allows users to input any Percent Within Limits (PWL) acceptance plan, along with the corresponding quality characteristics and their test results. The software then allows the user to compute payment factors; to consider the potential impacts of various changes in the process mean, standard deviation, or both; and to develop and display control charts.
PWL Pay should provide a powerful tool for contractors to use to track their processes, develop control charts, determine payment factors, analyze risks, and make informed decisions necessary to maximize profit while providing agencies with the quality product they desire. The software will provide agencies that do not already have a materials database a simple way of collecting and tracking contractor and agency test data.
