69 Implementation of the Recommended Practice Implementing an alternative pipe system selection and bidding process gives contractors the ability to choose from among alternative drainage pipe systems that are of satisfactory quality and are equally acceptable to the owner. This will promote competition and lower costs, and is the primary driver pushing the implementation of such a system.

71 (assuming that a champion at a specific DOT can be identified) • Training opportunities – Hosted and recorded webinars – Workshops at conferences and conventions 14.4.3 Industry Stakeholders As the Recommended Practice is implemented by the early adopter DOTs, it will be necessary to provide information and training to other industry stakeholders.

72 Participating agencies were chosen based on their interest and willingness to participate and in an attempt to access a wide range of agency policies applied to diverse drainage, climatological, and environmental conditions; technical evaluation criteria; and bidding practices. Specifically, variations in agency approach to design, alternative/optional bidding, post-installation inspection, geographic location, and other factors were considered in approaching and selecting agencies for participation.

73 – Abrasion is typically evaluated on a qualitative basis – Methods to couple evaluation of abrasion and corrosion are not widely used. Increase in EMSL from coatings is not standardized • The effectiveness of an alternative bidding protocol is predicated on the use of a broad inventory of pipe systems • Short hand inventory codes, similar to those used by MTO and NDOR provide benefit and facilitate tracking and transfer of design output into bid documents and quantity sheets • Post-installation inspections are an essential part of alternative pipe bidding to reduce risk of premature pipe system failure • The inspection requirements defined in current AASHTO guidance are thorough and robust and are recommended for increased adoption • Inspection methods that provide objective continuous records of quality indicators along the length of the pipe are preferred and are to be encouraged • Agencies that impart standard application of post- installation requirements typically allow a wide range of pipe systems • Widespread adoption of alternative bidding will likely require automation (most likely a software application)

74 The Recommended Practice has been designed in such a way that the results of future advances in research, standardization, and practice can be readily incorporated. The Recommended Practice retains an agency's flexibility to manage risk for each design component as per agency preference but makes a clear distinction between disqualifications made for technically justifiable reasons and disqualifications made for agency or designer preference.
