4.5.8 Hierarchy of PS&E Elements
In the PS&E, certain elements have precedence over others in the case of conflicting information. This hierarchy is discussed below:
- Numerical dimensions govern over scaled dimensions;
- Special provisions govern over plans (including general notes);
- Plans (including general notes) govern over standard specifications and special specifications; and
- Job-specific plan sheets govern over standard plan sheets.
However, in the case of conflict between plans (including general notes) and specifications regarding responsibilities for hazardous materials and traffic control in Items 1 through 9, “General Requirements and Conditions” and Item 502, “Barricades, Signs, and Traffic Handling,”
special provisions govern over standard specifications and special specifications, which govern over the plans.
