43 Chapter 6 ATC Implementation Toolkit This chapter describes a set of tools designed to assist agencies' implementation of ATCs on ACM projects. The actual toolkit is an interactive spreadsheet.

46 • Confidentiality considerations • Environmental review and permitting constraints • Design liability considerations • ATC ownership and incorporation of ATCs from unsuccessful proposals • Review and evaluation considerations For example, Figure 6.4 is a screenshot of the checklist for CATCs. It shows that the agency team works through each check point and determines whether it is applicable to the specific project.

48 Figure 6.6 Tool #3 – ATC Evaluation Attribute Example. The next step in the ATC evaluation framework is to determine if an ATC is equal to or better than the baseline design and develop the input for making trade-offs among various ATC objectives (e.g.

50 The final step is automatically generated by the tool using the input from all the previous steps. A weighted index is computed for the ATC and based on the conditions stipulated by the agency team in previous steps, a recommendation is made as shown in Figure 6.9.

53 challenges that otherwise would be addressed on a trial-and-error basis. It has probably been the case of most agencies currently using a mature set of ATC procedures, like MnDOT.

54 • MnDOT indicated that a challenging part of the ATC process is to ensure an effective and prompt evaluation of ATCs in order to prevent it from delaying other aspects of the procurement process. This is actually one of the purposes of Tool #3.
