126 9 GUIDEBOOK A Guidebook was developed as the primary means to convey research results. This section provides an overview of the Guidebook, which is available in a separate publication. The Guidebook defines highway construction sustainability and provides guidance on how to meaningfully incorporate it into highway projects. It is meant to be used by practitioners as an aid in communicating, implementing, and evaluating sustainable highway construction. Specifically, this Guidebook can be used to: ï· Define a common meaning for sustainability when included in construction procurement and contracting. ï· Describe owner sustainability goals and objectives more precisely in project procurement and contracting. ï· Identify what construction categories and practices best address what sustainability components. ï· Provide a source of sustainable construction practice (SCP) ideas. ï· Evaluate any construction practice for sustainability. ï· Aid in procuring and contracting sustainability. Key features of the Guidebook are: Audience and purpose. Intended for the highway construction industry: the practitioners who work for and with owner agencies, construction contractors, designers and related professions. It should assist in communicating sustainability in highway construction, selecting appropriate sustainable construction practices given project context, using sustainability as a criterion to evaluate highway construction practices, and specifying sustainability in procurement and contracts. Guiding principles: ï· Provide concise, useful information to practitioners. ï· Provide ideas, but do not tell industry how to construct highways. Scope. Only address sustainable highway construction practices that can be implemented now. Other practices that may be necessary for construction to occur (such as planning, design, permitting, funding), that happen once construction is complete (such as operations and maintenance), or that are not currently feasible (such as future technology) are not addressed. The focus is at the project level including project delivery and project-specific practices. A list of sustainable construction practices (SCPs) identified by the industry as viable and, in the right context, ready for implementation now. The Guidebook presents this list of 79 SCPs along with a construction and sustainability framework to organize it, and Appendix A expands on the list with more detail and rating of each SCP. A method for using sustainability as a criterion to evaluate any highway construction practice. The Guidebook presents a straightforward evaluation method that can be used as the
