Chapter 1 - Introduction

1.3. Guidance

The following definitions offer guidance for interpreting policy statements found in the GDOT Design Policy Manual:

May – The use of the word “may” indicates a permissive condition. Under this condition, the designer is encouraged to make a reasonable effort to follow the appropriate design criteria. In those instances where it is impractical to follow appropriate design criteria, the designer should use sound engineering judgment; no further GDOT authorization is required.

Shall/Will – The use of the words “shall” and “will” designates a mandatory condition and the designer must make every practical effort to follow the appropriate design criteria. In those instances where it is impractical to follow the appropriate design criteria, it will be necessary to request a Design Exception or Design Variance from the GDOT Chief Engineer.

Should – The use of the word “should” indicates an advisory condition. Under this condition, it is recommended, although not mandatory, that the designer follow the appropriate design criteria. In those instances where it is impractical to follow appropriate design criteria, the project manager shall receive approval from the appropriate Office Head. Acceptable documentation may be in the form of an email, letter to file, or meeting minutes. The project manager shall document the decision and approval in the Project Design Data Book. The criteria for the Project Design Data Book can be found in the GDOT Plan Development Process (PDP).
