Task 54, FY 1993, "Financial Impacts of Conversion to the Metric System" (The University of Alabama and Mr. Peter Smith). The AASHTO Standing Committee on Highway's Task Force on Metrication requested funding from Project 20-7 to assist in the identification of the factors that must be considered for conversion and to analyze cost impacts. The Task Force also decided that a Guide to Metric Conversion should be developed under this task to provide guidance to AASHTO and state and local transportation agencies on the steps, planning and procedures that will be necessary for conversion to metric. The procedures will emphasize aspects of cost minimization; i.e., methods for which unit costs and total costs at the state level can be minimized and possibly absorbed in existing budgets. The University of Alabama was selected to develop the guide document. In addition, a consultant from Ontario, Canada, was employed to document the steps, procedures, and engineering standards employed by the Province of Ontario during its conversion efforts in the mid-1970s. The draft guide was reviewed and approved by the Metric Task Force in October, and submitted to the AASHTO Board of Directors for action in 1992. A guide of recommended engineering standards was approved by the Task Force and the 20-7 panel in December 1992. The guide was adopted and published by AASHTO and the project is completed.
