American Association Of State Highway And Transportation Officials Guide For Design Build Procurement

This guide is intended to supply state highway agencies with strategies and methods for successful design-build implementation, including the preparation of requests for qualifications (RFQ) and requests for proposals (RFP) and the selection of a qualified proposer. It is based on best practices from experienced state highway agencies and other public sector agencies. Topics include understanding design-build, developing a design-build program, defining project goals, and allocating project risks. Over fifty contractual provision examples are provided.

The use of engineering consultants by state transportation agencies continues to be important in providing the appropriate solutions to transportation needs. This publication replaces the Guide for Contracting, Selecting and Managing Consultants in Preconstruction Engineering, published by AASHTO in 1996. In order to assess current practices, questionnaires were developed for both state and consultant practitioners. The responses showed significant growth in the volume of work done by consultants and in the range of services provided by consultants. The results of these surveys, along with the collective experience and expertise of the technical committee membership, were used to restructure much of the guide and to update and expand the discussion of current practices for the effective use of consultants.

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 402: Construction Manager-at-Risk Project Delivery for Highway Programs explores current methods in which state departments of transportation and other public engineering agencies are applying construction manager-at-risk (CMR) project delivery to their construction projects. CMR project delivery is an integrated team approach to the planning, design, and construction of a highway project, to help control schedule and budget, and to help ensure quality for the project owner. The team consists of the owner; the designer, who might be an in-house engineer; and the at-risk construction manager. The goal of this project delivery method is to engage at-risk construction expertise early in the design process to enhance constructability, manage risk, and facilitate concurrent execution of design and construction without the owner relinquishing control over the details of design as it would in a design-build project.

Context-sensitive solutions (CSS) reflect the need to consider highway projects as more than just transportation facilities. Depending on how highway projects are integrated into the community, they can have far-reaching impacts beyond their traffic or transportation function. CSS is a comprehensive process that brings stakeholders together in a positive, proactive environment to develop projects that not only meet transportation needs, but also improve or enhance the community. Achieving a flexible, context-sensitive design solution requires designers to fully understand the reasons behind the processes, design values, and design procedures that are used. This AASHTO Guide shows highway designers how to think flexibly, how to recognize the many choices and options they have, and how to arrive at the best solution for the particular situation or context. It also strives to emphasize that flexible design does not necessarily entail a fundamentally new design process, but that it can be integrated into the existing transportation culture. This publication represents a major step toward institutionalizing CSS into state transportation departments and other agencies charged with transportation project development.

"TRB's National Cooperative Highway Research Program (NCHRP) Report 753: A Pre-Event Recovery Planning Guide for Transportation is designed to help transportation owners and operators in their efforts to plan for recovery prior to the occurrence of an event that impacts transportation systems. The guide includes tools and resources to assist in both pre-planning for recovery and implementing recovery after an event. NCHRP Report 753 is intended to provide a single resource for understanding the principles and processes to be used for pre-event recovery planning for transportation infrastructure. In addition to the principles and processes, the guide contains checklists, decision support tools, and resources to help support pre-event recovery planning."--Publisher description.

This Supplement includes alternative design procedures that can be used in place of or in conjunction with the American Association of State Highway and Transportation Officials (AASHTO) "Guide for the Design of Pavement Structures", Part II, Section 3.2, Rigid Pavement Design, and Section 3.3, Rigid Pavement Joint Design. The Supplement contains the recommendations from National Cooperative Highway Research Program (NCHRP) Project 1-30, modified based on the results of the verification study conducted using the Long Term Pavement Performance (LTPP) database.

Written for water and wastewater utility personnel, the collection of 30 articles provides a basic template of how DB projects can be planned, procured, and executed. Discussions include how the processes and procedures of design-build differ from those of design-bid-build, their impact on preliminary design and planning, procurement, and project execution.
