Book Description
'TRB's National Cooperative Highway Research Program (NCHRP) Report 574: Guidance for Cost Estimation and Management for Highway Projects During Planning, Programming, and Preconstruction explores approaches to cost estimation and management designed to overcome the root causes of cost escalation and to support the development of consistent and accurate project estimates through all phases of the development process, from long-range planning, through priority programming, and through project design. NCHRP Web-Only Document 98 details the steps followed by the research team in the development of NCHRP Report 574"--Publisher's description.

Book Description
Under the Virginia Transportation Act signed into law in April 2000, more than $10 billion would have been invested in highway construction, public transportation, airports, and ports during the following 6 years. However, recent budgetary constraints will result in a delay in investing more than $2 billion in road projects for more than a decade. In the current study, a previously developed comparison tool was extended to bring quantitative evidence of safety and categorical evidence of broad motivations to planners, engineers, and the public in comparing the benefits of proposed transportation projects. The extended tool developed in the current study provides visual devices for presenting multifaceted information about project attributes. Policymakers and planners may find the presentation useful in assessing what types of projects are being undertaken and what projects to prefer to others. The extended tool represents project information including cost, average daily traffic, and crash rates for comparison and prioritization of the 1,500 candidate projects that constitute the development plan of Virginia highways. The extended tool is flexible to accommodate applications such as project selection (planning) and programming. Several sources of information include the crash databases of the Virginia Department of Transportation (VDOT) and project plans for districts and localities. The extended tool enables planners to identify principal motivations for various projects based on categories defined by the Transportation Equity Act for the 21st Century. The tool introduces summary reports of criteria including project aggregate costs and counts of projects with particular motivations, facilitating system-level analyses and project ranking. The summary reports can be useful to interpret outcomes of human deliberation or multicriteria rating and ranking processes, some of which are demonstrated in this study in the body of the report and in a substantial appendix. The major innovation of the extended comparison tool is its ability to synthesize the relevant quantitative and categorical information on a large and diverse portfolio of highway investments, bringing more evidence to the table earlier in the planning process. Three case studies demonstrate the application of the extended comparison tool in short-, medium-, and long-term transportation plans. These case studies are the VDOT-Culpeper District Transportation Development Plan (a 6-year plan), long-range financially constrained plans of selected small Virginia localities, and the long-range plan of the Thomas Jefferson Planning District Commission. The incremental data to assess over 100 projects in a VDOT District Six-Year Plan were collected in 90 minutes, providing an advantage over typical methods that can require several hours or more per project. Recommendations are given for implementation of the extended comparison tool and further development of the software prototype.

Book Description
Successful highway construction is measured by cost, time, safety, and quality. One further measure of success is the quantity of Request for Information's (RFI) submitted and their impact. An RFI is a formal written procedure initiated by the contractor seeking additional information or clarification for issues related to design, construction, and other contract documents. The RFI process was identified as an important best practice for the delivery of major highway project and as a significant source of benchmarking and metric opportunities. Implementation of an RFI process is considered to be an integral part of successful project management for construction projects because it improves communication between the construction, design, and project management teams. The ability to quantitatively measure the performance of the RFI process has the potential to identify areas of concern within a project, to breakdown the reasons for why an RFI is submitted, and to understand the expected submittal rate of RFIs. However, there are no studies completed on the quantitative evaluation of the RFI process for highway construction. Even though the procedure for using RFIs has been documented by State Highway Agencies (SHAs), there are currently no available benchmarks or metrics identified as performance measures for use within the RFI process for major highway projects.

Book Description
The federal-aid highway program provides $33 billion a year to states for highway projects. The fed. gov¿t. provides funding for and oversees this program, while states largely choose and manage the projects. This report reviewed the Federal Highway Admin.'s (FHWA) implementation of several requirements in the Safe, Accountable, Flexible, Efficient Transportation Equity Act: (1) oversight of states using a risk management approach; (2) efforts to develop minimum standards for estimating project costs, and periodically evaluate states' cost estimating practices; and (3) reviews of states' financial management systems. Also reviews FHWA's policy on presenting an estimate of financing costs in financial plans for major projects. Charts and tables.
