Book Description
The selection of a project delivery method is a complex decision that can greatly affect the project outcome. Multiple methodologies have been developed to facilitate the selection for private entities as well as for public entities, like State Highway Agencies. The elements examined during the selection process include project characteristics, desired goals, institutional constraints, and the proper risk allocation. Within the highway sector, the principal choice of delivery method is between Design-Bid-Build, Design-Build, and Construction Manager/ General Contractor. In Texas, only the Design-Bid-Build and Design-Build methods are legislatively available. To ensure the effectiveness of the project delivery method selection, many State Highway Agencies have developed decision-making tools/ methodologies. Use of these tools allows the empirical investigation to refine our understanding of the factors that guide selection and their potential interactions. In particular, this study utilizes data from a quantitative tool developed for the Texas Department of Transportation. Since 2014, 57 projects have been evaluated by the tool, providing a large dataset for analysis. Specific findings identify the most impactful decision elements for each delivery method selection, such as site conditions and utility relocations for Design-Bid-Build and opportunity for innovation for Design-Build. Among the project characteristics, those most commonly selected as applicable include early project completion, site conditions, designer-contractor integration, and contractor better at handling third-party issues. Correlations measured among applicability of characteristics find some strong positive correlations, principally among the characteristics relating to innovation and designer-contractor integration. The emergence of need for innovation as a primary element of the decision is further examined by assessing the complexity of the evaluated projects through a Project Information Sheet distributed to TxDOT practitioners. The findings of this analysis indicated that complexity of design elements is highly correlated with innovation and that traffic challenges are the most common element increasing project complexity. These findings are also evaluated using importance weightings generated by an expert panel. The quantitative results are useful both for practitioners seeking to refine their project delivery method decision-making process and for researchers seeking a quantitative basis for future investigation

Book Description
Time delays and cost overruns in construction projects are generally due to factors such as inappropriate planning, design errors, unexpected site conditions, inadvisable tools selection, change scope, weather conditions, lack of resources, and other project changes. Time delays and cost overruns are of concern to most project managers, owners, and governments. These elements of time and cost are two of the critical defects that impact the construction project delivery. These defects can lead to project failures and to various negative issues like increasing in disagreements among the project team, the contractor, suppliers, and the owner. State Departments of Transportation (DOTs) in the U.S. continue to spend heavily on roads, highways, and bridges construction, as well as development, maintenance, and expansion. This continued financial commitment reflects decades of commitment to improve the transportation service for safer and better use by the general public. Despite the notable efforts from most of the states to develop the transportation infrastructure, budget restrictions and lack of funds are some of the major challenges faced by DOTs. Highway and bridge infrastructure has a high potential growth in the U.S. construction market. Well-organized highway and bridge project investment decision-making becomes increasingly crucial in the transportation sector. In this research, transportation is specified to highway and bridge projects, and it focused on high-profile projects. All states are working with their state transportation plan, listing the projects based on each state priorities and population growth. Proper planning leads to the right decision regarding selecting the best alternative within budget, and it must reflect certain core principles, including a comprehensive analysis. To facilitate such a decision process, decision makers need a trusted decision model that considers all important options and impacts. By using a decision model, decision-making will not be subjectively influenced to favor one option or group. The decision model becomes the primary tool for selecting the best option, based on its structure levels, perspectives, sub-criteria, and experts’ input. Recently, there is an apparent need for a decision model to help DOTs evaluating their options. Effective project delivery assessment tools, techniques, or practices are strongly needed to improve transportation construction projects’ performance. The research objective is to develop a comprehensive decision model that can be used by project managers and their teams to choose the most effective project assessment technique for measuring the success of performance and outcomes related to the delivery of transportation projects. This research was focused on the assessment techniques that are used in the development phase within the transportation project lifecycle phases.

Book Description
Describes various project delivery methods for major airport capital projects. The guidebook also evaluates the impacts, advantages, and disadvantages of these various project delivery methods. The project delivery methods discussed include design-bid-build (DBB), construction manager at risk (CMR), and design-build (DB). The guidebook offers a two-tiered project delivery selection framework that may be used by owners of airport projects to evaluate the pros and cons of each delivery method and select the most appropriate method for their project. Tier 1 is an analytical delivery decision approach that is designed to help the user understand the attributes of each project delivery method and whether the delivery method is appropriate for their specific circumstance. Tier 2 uses a weighted-matrix delivery decision approach that allows users to prioritize their objectives and, based on the prioritized objectives, select the delivery method that is best suited for their project. The report will be helpful to airports with determining the most appropriate project delivery methods (e.g., DBB, DB, or CMR) for various types of airport capital projects.

Book Description
This guidebook demonstrates how a state transportation agency (STA) can improve its project scoping process (PSP) and practices to produce a project cost estimate and schedule that facilitate programming decision making and accountability. It illustrates the effort needed to develop a robust cost estimate and then manage to a baseline budget and scope throughout the project delivery cycle. The guidebook consists of two parts. Part 1, “Research Results about the PSP,” addresses the following issues: why STAs should formalize the PSP; current practices for PSP; and how agencies can implement an effective PSP. Part 2, “Implementation Guidelines,” provides an easy-to-understand layout and describes how to implement the PSP. The guidelines are divided into three sections. Each section details one of the three major activities of the PSP—develop the project, analyze the alternatives and document findings, and develop the recommended alternative. The guidelines also have two appendices. The first appendix summarizes the tools that can be used while performing different activities in the scope development process. The second appendix is the list of online links to various resources and tools to support the PSP, as referenced in this guidebook.
