Abstract

The design of the Contractor Payment System was started in June of 1968. The system was implemented in March of 1969. Prior to the implementation of this system all documents necessary in paying a contractor and reporting progress on construction projects were prepared by the individual field offices responsible for each project. In order to eliminate the excessive amount of paper work in the field offices, it was decided to place the work load of determining the amount of progress payment to the contractors and preparation of progress reports on the computer. In addition to this the computer also keeps track of the total quantities in place, the amount of money retained to date, percentage of contract time elapsed, and percentage of work completed on each contract.
