ATC Implementation Toolkit 51 essentially lays out the major risks and opportunities faced by most typical projects. Tool #1's underlying assumption is that a project should have sufficient flexibility in its technical content and administrative arrangements to permit viable options to be generated by industry during procurement.

54 Guidebook for Implementing Alternative Technical Concepts in All Types of Highway Project Delivery Methods Experience has shown that many agencies have a third outcome from their ATC evaluation methodologies, and that is to issue a conditional approval. This occurs when the ATC is deemed attractive but has one or more shortcomings that must be corrected before it can be approved.

ATC Implementation Toolkit 57 However, because the Community Impact attribute was assessed to not be equal to the baseline, but was believed to be correctable, a conditional approval is recommended. The value of Tool #3 is not only in its functional output but also in the documentation that is generated as an agency team develops the input that is used to generate the recommendations.
