Available in PDF, EPUB and Kindle. Book excerpt: In May 2002, Virginia's Commonwealth Transportation Commissioner tasked his Chief of Technology, Research & Innovation with leading an effort to develop a definitive, consistent, and well-documented approach for estimating the cost of delivering construction projects. A task force that included Virginia Department of Transportation (VDOT) central and district office staff, Virginia Transportation Research Council staff, Commonwealth Transportation Board members, and a metropolitan planning organization member was formed to either locate a well-founded, tested method for estimating project costs that could be adapted for use by VDOT or develop one. The task group found that a VDOT district had been using an estimation worksheet for several years that produced consistent and reliable results for certain types of roadway and bridge construction. The task group determined that no other method examined had the specificity and potential of this tool. The project team expanded the tool by collecting extensive project data and obtaining evaluations of VDOT project management personnel statewide to develop it further. The existing Excel worksheet with roadway and bridge estimates was expanded to include construction engineering, to be applicable for interstates, and to generate estimates for right-of-way and utilities costs. Data on completed projects were collected from all VDOT districts to help calibrate the model further to account for cost variations across the state. The task group also recognized early on that a very strong focus on project scoping was essential to accurate project estimation. A previous VDOT scoping committee had determined that VDOT did not have a consistent, uniform method that was being used statewide to scope projects. As a result, project cost estimates made at the scoping stage often did not hold up over time because key project features were invariably overlooked. The result was inaccurate estimates. Testing of the cost estimation tool was completed in the summer of 2003. Analysis of a sample of completed VDOT construction projects throughout the state showed that the tool yielded results that, on average, differed from actual final project costs by 22 percent. After further modifications, the Project Cost Estimation System (PCES), as it was named, became a fully operational system for VDOT in October 2003. The PCES is composed of three elements: a cost estimation tool, an improved scoping process, and a project development website. The responsibility for maintaining and updating the PCES now rests with VDOT's Scheduling & Contract Development Division.

This book was released on 2006 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report warrants consideration in the development of goals, performance measures, and standard cost-benefit methodology required of transportation agencies by the Virginia 2006 Appropriations Act. The Virginia Department of Transportation has begun to implement a quantitative methodology as an aid to prioritizing highway construction projects in four categories: interstate, primary, urban, and rural. The methodology adopts fifteen quantitative metrics including level of service (LOS), volume-to-capacity ratio, traffic flow, intermodal access, crash rate, emergency route access, heavy truck usage, unemployment rate, environmental issues, right-of-way use, use of alternative transportation modes, bridge sufficiency rating, and cost-effectiveness. The results of the methodology are used by executive review teams to negotiate, interpret, and support decisions regarding the selection of construction projects for funding in a $1.8 billion construction program. This report describes an effort to extend the current prioritization methodology via modeling and uncertainty analysis of the risk reductions, benefits, and costs that are expected of candidate construction projects. The report (1) develops monetized estimates of benefits in several categories including crashes avoided, travel time saved, fuel uses avoided, and emissions avoided; (2) compares the estimates of benefits to the estimates of project costs, representing the uncertainty of the results as numerical intervals; and (3) compares the results to the results of the prioritization methodology that is currently in use. The major contribution of the report is the assembly of existing and new methods of benefits assessment via an interval analysis of uncertainty that enables a prioritization to proceed with sparse data on a large number of potential projects. With the interval analysis of uncertainty, a decision maker is provided with a sound basis to recommend that more data are needed or that existing available data are sufficient to distinguish among the potential projects. The developed methodology is demonstrated with project data from VDOT's Northern Virginia District using a database of performance criteria of 53 candidate projects ranging in cost from $2 million to $130 million. A prototype of a prioritization software was developed along with the report for the support of future analyses.

Book Synopsis Review of Operations in the Virginia Department of Transportation's Project Development Process by : Benjamin H. Cottrell
Download or read book Review of Operations in the Virginia Department of Transportation's Project Development Process written by Benjamin H. Cottrell and published by . This book was released on 2007 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Virginia Department of Transportation's (VDOT's) project development process (PDP) directs how construction projects are developed. The purpose of this study was to evaluate the manner in which operations is currently considered throughout the PDP and to identify opportunities to expand and enhance the consideration of operations such that the outcome is a more efficient and effective roadway system. The term operations refers to the safe, efficient, and effective movement of traffic on the highway system. Overall, the PDP is working well with regard to addressing traffic engineering issues. The project team process is valuable in reviewing and developing plans. Although there is some variety in the manner in which TE staff participates in the PDP across regions, there is consensus that the process is most effective when TE staff members are involved regularly and throughout the process. A blend of flexibility to account for the uniqueness of projects and project teams and consistency in the application of the basics of the PDP is important. Communication among all PDP team members is a critical component of the process. The resolution of recommendations brought by any team member needs be documented and disseminated to all team members. Checklists used to ensure that all issues have been addressed are not currently universally employed but are considered valuable in instances where team members are new to the process or the team desires the additional structure checklists provide. Clear procedures for dispute resolution are needed to improve the PDP process when consensus cannot be reached on recommendations. Recommendations are offered for improving the operations aspect of the PDP, including providing a description of role and responsibilities of the TE staff in the PDP, providing guidance as to who has responsibility and accountability for TE and safety-related items in the plans, reviewing the process for establishing a schedule and budget to make certain that adequate time is provided for project development and reviews with a focus on program management, and examining the opportunity to begin the PDP concurrent with the end of the planning process.

This book was released on 1998 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this effort is to assist the Virginia Department of Transportation (VDOT) in improving the comparison in planning of potential primary and secondary roadway improvement projects. Historical projects that have been implemented or considered for implementation have been used as a case study data set. Methods are proposed for estimating cost, performance gain and crash risk reduction of future roadway projects, with the main focus being the presentation of trade offs among these criteria. If, in a particular case, more accurate and/or appropriate data is available for one or more of these criteria (e.g. from a simulation study that has been performed), then this information can easily be used to supplement or replace the estimations proposed here. The project comparison instrument combines three major decision making attributes in project selection: crash risk, performance, and project cost. By quantifying these attributes across a number of proposed highway improvement projects, projects can more readily be compared to one another, and a more holistic view of potential projects is achieved. This is an important step when choosing a portfolio of projects each year. In order to compare projects, attributes are quantified in the following manner for planning level decisions. Crash risk reduction is calculated as the number of crashes avoided per year at the project site. Particular roadway improvements are typically assumed to decrease the expected number of crashes by a statistically determined and pretabulated percentage. Performance gain is quantified by the vehicle minutes of travel time avoided in the peak hour. Finally, cost is modeled as the sum of preliminary engineering, right of way and construction costs. Once the objectives are quantified, they can be graphically displayed in a Project Comparison Chart. Examples for applying this approach are given in the text and in the accompanying workbook.
