Key Findings The use of ATCs in ACM projects continues to furnish a mechanism to obtain early contractor design involvement with the goals: Improving the project s final technical quality, Improving both cost and schedule certainty. The use of ATCs is increasing. However, most of the growth remains in DB and P3 projects. NCHRP 08-112 ATC Guidebook 4
Key Findings The use of DBB ATCs has not been perceived as attractive by most DOTs. Primary technical issue is the time it takes to receive, evaluate, and approve proposed ATCs in a traditionally short procurement period. Primary risk issue is the assignment of design liability and complications added by only modifying individual features of work. Limited scope DBB ATCs where the allowable changes are restricted to temporary works and traffic control seem to provide the most potential for growth in this area. Opportunities during procurement to propose alternatives to the solicitation s scope has been expanded: Alternative financial concepts (AFC) in P3 Alternative configuration concepts (ACC) in DB. Pre-Approved Elements (PAE): utilities, geotechnical investigations, etc. NCHRP 08-112 ATC Guidebook 5
Proposed Working Definition Synthesizing the various definitions discussed above leads to a working definition for ATCs that satisfies the following tests: The alternative must modify a specific contract requirement in a manner that is not contemplated by the project s solicitation. It must be equal to or better than the baseline design as determined by the agency advertising the project in a verifiable manner. Incorporating the above tests into a single definition results in the following: An ATC is a proposed modification to a contract requirement in a manner that is equal to or better than the baseline articulated in the project s solicitation.

Typical Project Delivery Method Appendix Flow chart Example CATC/ATC submittal form Example Evaluation Plan Conceptual Alternative Technical Concept Submittal Form General Description: A narrative that describes the proposed ATC in concept and includes the basic differences between the BTC and the ATC, the location where the ATC will be used on the project, and any design exceptions required by the ATC. Design-Build Project Proposer ATC Number Advantages and Disadvantages: A listing and brief description of the comparative advantages and disadvantages of the Conceptual ATC including: Effects on the service life, safety, durability, reliability, economy of operation, ease of maintenance; other factors significantly altered by the Conceptual ATC; and rationale for the proposed deviation(s) from the BTC. Impacts to Permits and/or Third-Party Agreements: A description of steps necessary to address existing permits, new permits, or third-party agreements that may be impacted or required in order to initiate the proposed Conceptual ATC. In addition, the Bidder shall describe its expectation of securing or modifying these documents; and the responsible party(s) and time frames required to implement such requirements. Identification of Prior Similar ATCs: If the Conceptual ATC has been used under comparable circumstances, provide details of other projects where it has been used under comparable circumstances, and the action taken by the relevant agency. Known Use or Testing: A description of any previous use or testing of the Conceptual ATC that is known to the Bidder, including the tester, the conditions, and the results. Identification of Interdependencies: A brief description of interdependent components of each ATC NCHRP 08-112 ATC Guidebook 11
Visual Content Maximized Risk Assessment Example ATC Evaluation Factors Project Development and Delivery Process - DB FACTOR TYPE FACTOR 30% DB Contract Award Proposed ATC complies with current project design criteria. ATC does not require a design deviation. Proposed ATC PAM matrix score is greater than or equal to the baseline PAM matrix score. Proposed ATC cost is less than the engineer s estimate for the modified feature of work. Proposed ATC schedule is less than the period specified in the solicitation. Proposed ATC costs more but has a lower life cycle cost. Proposed ATC cost savings are validated. Proposed ATC meets minimum net savings amount after re- design costs Proposed ATC reduces the period traffic is disrupted. Proposed ATC schedule savings are validated. Proposed ATC reduces the construction period for the modified feature of work. Proposed ATC changes to the baseline design criteria have been successfully used in another US agency. Proposed ATC reduces internal agency oversight costs.

Summary Draft Guide is in panel review. Next step is to vet the draft of the revised guide with two DOTs. Vetting #1 Experienced DOT Colorado, Ohio, Minnesota, or Washington State Vetting #2 DOT new to ATCs Alabama or Nebraska Developing an implementation toolkit to go along with the guide ATC project early identification tool ATC model contract clauses and risk mitigation tool Equal to or Better Than decision tool. Training material as needed. Project is on schedule - Final completion March 31, 2019 Welcome any feedback dgransberg@gransberg.com NCHRP 08-112 ATC Guidebook 13
