Book Synopsis Lessons Learned from the Selection of Project Delivery Methods in Highway Projects by : Vassiliki A. Demetracopoulou
Download or read book Lessons Learned from the Selection of Project Delivery Methods in Highway Projects written by Vassiliki A. Demetracopoulou and published by . This book was released on 2019 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Evaluating Project Assessment Techniques for High-Profile Transportation Projects Development and Delivery by :
Download or read book Evaluating Project Assessment Techniques for High-Profile Transportation Projects Development and Delivery written by and published by . This book was released on 2019 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis A Guidebook for Selecting Airport Capital Project Delivery Methods by : Ali Touran
Download or read book A Guidebook for Selecting Airport Capital Project Delivery Methods written by Ali Touran and published by Transportation Research Board. This book was released on 2009 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Development of a Decision-support Tool for TxDOT Delivery Methods Selection by : Mayra Soledad Martinez
Download or read book Development of a Decision-support Tool for TxDOT Delivery Methods Selection written by Mayra Soledad Martinez and published by . This book was released on 2015 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alternative delivery methods for transportation infrastructure projects, besides the traditional Design-Bid-Build (DBB) approach, have been implemented by private and public sectors since the last decades. The Texas Department of Transportation (TxDOT) is not the exception, and the fact that TxDOT has available alternatives for delivering its projects lead to the need of a formal decision process. This work presents the existent approaches made by different owner entities to formalize the delivery method decision. This research provides with decision procedures, criteria and principles to develop a quantitative decision-support tool; thus serving any entity seeking for a formalized and documentable Delivery Method decision procedure. A complete decision process was developed specifically for TxDOT, based on the literature review findings, but also on the agency's needs, experience and legal authority. This work intends to help the agency's staff make an informed choice between their available delivery methods: Design-Bid-Build and Design-Build. The decision method was formalized in the way of a Multiple Criteria Decision Making (MCDM) process, and organized as a MS Excel decision-support tool. The process incorporates knowledge --in the shape of performance scores-- from TxDOT experts as well as from other organizations that work closely with the agency. This input allows for the creation of a tool fully customized for TxDOT goals and projects' characteristics. The decision-support tool developed incorporates quantitative measures, but is transparent and flexible. It constitutes a rigorous, repeatable and documentable decision process, evaluating characteristics and goals of each project to determine each delivery method's suitability degree. Overall, the present works provides with guidelines for the development of a decision-support tool regarding the delivery methods decisions for any entity needing to formalize the process. It also specifically contributes to TxDOT, producing a formalized decision process that may be taken as an example for any other entity willing to modify and quantify their current Delivery Method selection procedure.

Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
