Bridge Standard Practices
Accelerated Bridge Construction (ABC) Decision Process
The ABC Decision Matrix has been adopted as a Bridge Design Standard Practice. It will be used to assess the viability of accelerated bridge construction methodology during the preliminary design phase of all projects involving bridge deck replacement, superstructure replacement or entire bridge replacement. Below is a guide that explains the use of the worksheet and definitions of the input variables obtained from project preliminary design development. The results of the accelerated bridge construction assessment for any project should not be considered to be absolute as other factors not included in the decision matrix may be significant. However, accelerated bridge construction design methodology should be very strongly considered where the results of the worksheet analysis are favorable for accelerated bridge construction.
