The basis-of-design plan sheet is not intended for construction and should not be included with
the bid set. The sheet is inserted after the project has begun. See DSG Chapter 1, Design Process.
5.4.2 Design Criteria List
The design engineer may use a design criteria list to develop a basis-of-design plan sheet. The
design criteria list is a shortened version of the most important design requirements (Table 5-2).
For water system infrastructure, this information includes how key design criteria were selected,
including working pressure, flow rate, and types of joints.
The list shows information that may be shown on the basis-of-design plan sheet. However, the
list is not intended for construction and should not be included with the bid set. If included with
the bid set, the design criteria list should be labeled “Informational Only.”
Typically, the design criteria list is completed with the preliminary engineering report as a
concise summary. However, that report can provide a much lengthier description of design
requirements.
Table 5-3 is an example of what a design criteria list might contain for a water facility design.
Note: Table 5-3 is only an example. It is not intended to explain technical concepts.
