I was reviewing some of the New York State Department of Transportation Standard Specifications, general information to Contractors. As you know at one time NYSDOT was 100% metric, one of the earliest agencies to convert and one of the last to return to US Customary. However, a bit of metric legacy remains in the following section.
Safety Data Sheets, catalog cuts, manufacturer's directions and other documents prepared for general use may use U.S. Customary (USC) or International System of Units (SI) measurement units, or units from both systems. In drawings and documents containing dual units, the USC units shall be the primary units, and the USC units will be reviewed. The Contractor shall be responsible for all annotations on the source documents, conversions between the measurement systems and all errors resulting therefrom. Measurements, dimensions, and all other numerical data included in contract specific documents such as Material Acceptance Records, shop drawings, computations, and Material Details shall be presented in USC units, but they may also include SI units within parenthesis. The USC units shall be listed first, will take precedence and reviews will be based on these units. Documents that fail to adhere to this convention will be rejected. Howard Ressel NYSDOT Retired
