Book Synopsis Estimating User Costs as a Basis for Incentive/disincentive Amounts in Highway Construction Contracts by : James S. Gillespie
Download or read book Estimating User Costs as a Basis for Incentive/disincentive Amounts in Highway Construction Contracts written by James S. Gillespie and published by . This book was released on 1998 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Virginia Department of Transportation (VDOT) occasionally includes an incentive/ disincentive for early completion (I/D) in its construction contracts. This report presents the results of a project to identify procedures that would (1) enhance the effectiveness and enforceability of the I/D provision and (2) reduce the staff time and effort necessary to determine the need for an I/D and to calculate an appropriate per-day dollar amount. The researcher first reviewed the relevant literature pertaining to construction contracts and to road user cost calculation, and then evaluated the available user cost methodologies, especially computer software. Next, the researcher surveyed the current use of I/D provisions in Virginia and other states, and described VDOT's current project development process, with special emphasis on the user cost data that are typically generated during that process. The report makes five conclusions. First, various forms of I/D, though known by a variety of names, are fundamentally similar. Second, use of an incentive rather than a disincentive alone enhances the enforceability of the disincentive clause, though it may increase the final cost of the contract. Third, cost-plus-time bidding enhances the effectiveness of the incentive clause and the enforceability of the disincentive clause. Fourth, the end of the design public hearing is a logical point for VDOT to judge the need for an I/D. Fifth, road user cost savings calculated from the output of the Highway Capacity Software already in common use in VDOT forms a legally sound justification for a per-day dollar I/D amount.

Book Synopsis Use of Incentive/Disincentive Contracting to Mitigate Work Zone Traffic Impacts by : Andrew R. Mackley
Download or read book Use of Incentive/Disincentive Contracting to Mitigate Work Zone Traffic Impacts written by Andrew R. Mackley and published by . This book was released on 2012 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Incentive/disincentive clauses (I/D) are designed to award payments to contractors if they complete work ahead of schedule and to deduct payments if they exceed the completion time. A previously unanswered question is, "Did the costs of the actual work zone impacts that were avoided justify the incentives paid?" This paper answers that question affirmatively based on an evaluation of 20 I/D projects in Missouri from 2008 to 2011. Road user costs (RUC) were used to quantify work zone impacts and included travel delays, vehicle operating costs, and crash costs. These were computed using work zone traffic conditions for partial-closure projects and detour volumes and routes for full-closure projects. Conditions during construction were compared to after construction. Crash costs were computed using Highway Safety Manual methodology. Safety Performance Functions produced annual crash frequencies that were translated into crash cost savings. In considering an average project, the percentage of RUC savings was around 13% of the total contract amount, or $444,389 of $3,464,620. I/D provisions were very successful in saving RUC for projects with full-closure, projects in urban areas, and emergency projects. Rural, non-emergency projects successfully saved RUC but not at the same level as other projects. The I/D contracts were also compared to all Missouri Department of Transportation contracts for the same time period. The results show that I/D projects had a higher on-time completion percentage and a higher number of bids per call than average projects. But I/D projects resulted in 4.52% higher deviation from the project budget and possibly more changes made after the award. A survey of state transportation departments and contractors showed that both agreed to the same issues that contribute to the success of I/D contracts. Overall, in terms of work zone impact mitigation, I/D contracts are very beneficial at a relatively low cost.

Book Synopsis Optimal Incentive/Disincentive Determination Between Cost and Benefit by : Piyush Sharma

Available in PDF, EPUB and Kindle. Book excerpt: In an effort to motivate contractors to complete construction projects early on high-impact highway pavement construction projects, state transportation agencies (STAs) including TxDOT have often used incentive/disincentive (I/D) contracts. However, determining I/D rates is extremely difficult due largely to the lack of systematic methods for helping STAs determine effective I/D rates. The primary goal of this project is to develop a novel framework for determining the most realistic and economical I/D dollar amounts for high-impact highway improvement projects. To achieve its goal, this project proposes an integration analysis including project schedule and the lower and upper bounds of the I/D contract. The lower bound is the contractor's additional cost of acceleration, and the upper is the total savings to road users and to the agency. The study data were gathered using Construction Analysis for Pavement Rehabilitation Strategies (CA4PRS) software. These data were then grouped by four different types of pavements, namely Joint Plain Concrete Pavement (JPCP), Continuously Reinforced Concrete Pavement (CRCP), Hot Mix Asphalt (HMA), and Milling and Asphalt Concrete Overlay (MACO). With these data, a series of regression analyses were carried out to develop predictive models for the validation of time-cost tradeoff to determine I/D lower bound. Road user cost and agency cost savings were quantified using CA4PRS to develop lookup tables to determine I/D upper bound. Adjustment of contractors' additional cost of acceleration with Level of Service (LOS) and total savings adjustment using Net Present Value (NPV) were incorporated in the research study to calculate point based estimates of I/D for lower and upper bound, respectively. Lastly, case studies on real world projects were conducted to evaluate robustness of the model. The research results reveal that the predictive models give appropriate results for the case studies in determining the I/D dollar amount for the lower and upper bound. This study will provide the research community with the first view and systematic estimation method that STAs can use to determine the most economical and realistic I/D dollar amount for a given project- an optimal value that allows the agency to stay within budget while effectively motivating contractors to complete projects ahead of schedule. It will also significantly reduce the agency's expenses in the time and effort required for determining I/D dollar amounts.

Book Synopsis Systematic Procedures to Determine Incentive/disincentive Dollar Amounts for Highway Transportation Construction Projects by : Jae-Ho Pyeon
Download or read book Systematic Procedures to Determine Incentive/disincentive Dollar Amounts for Highway Transportation Construction Projects written by Jae-Ho Pyeon and published by . This book was released on 2012 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Federal Highway Administration has encouraged state transportation agencies to implement Incentive/Disincentive (I/D) contracting provisions for early project completion. Although general guidelines to determine the I/D dollar amount for a project are available, there is no systematic and practical tool in use to determine optimum I/D dollar amounts for I/D projects considering road user cost, agency cost, contractor acceleration cost, and contractor cost savings. Therefore, systematic procedures and models to assist project planners and engineers in determining an appropriate I/D dollar amount are essential to optimizing the use of I/D contracting techniques. This research performed a literature review related to the determination of daily I/D dollar amounts. Caltrans I/D project data were then collected and evaluated. Project performance data were analyzed with regard to project outcomes in two key areas: project time and project cost. Statistical analyses were performed to identify the impact of I/D dollar amount on project time and cost performance. Using Construction Analysis for Pavement Rehabilitation Strategies (CA4PRS) software, Caltrans I/D projects were analyzed to introduce three different levels of CA4PRS implementations for the I/D dollar amounts calculation. Based on the results of the I/D project case studies, the systematic procedures to determine appropriate I/D dollar amounts were developed using the CA4PRS schedule-traffic-cost integration process for the new I5 rehabilitation project in LA. The proposed procedures were applied to a typical highway pavement rehabilitation project using HMA (hot mix asphalt) materials. Further research is needed to apply the proposed model to other types of highway projects, with adjustment for the type of project.

Book Synopsis Project Development Methodologies for Reconstruction of Urban Freeways and Expressways by : James B. Saag
Download or read book Project Development Methodologies for Reconstruction of Urban Freeways and Expressways written by James B. Saag and published by Transportation Research Board. This book was released on 1999 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis presents a review of the current practices associated with the techniques and policies employed by state and local transportation agencies to address the many project development issues required for the reconstruction of existing urban and suburban freeways and expressways. This topic is of special interest because there is a need to reconstruct many highway facilities that have been in existence for over 40 years. The need arises both from the deterioration of the infrastructure and from changes in capacity requirements. This synthesis will be of interest to state and local highway design engineers, traffic engineers, finance and contracting specialists, and contracting personnel in these agencies. It will also be of interest to consultants who are engaged in freeway/expressway reconstruction projects. While many of the project development methodologies in practice for reconstruction of urban and suburban freeways and expressways are similar to those used for new construction, there are unique differences that apply primarily to the reconstruction of major urban highway facilities. This report of the Transportation Research Board highlights the similarities and differences in the planning and management of projects as well as in contracting and financing innovations. Methods for effectively managing traffic during the reconstruction process are important to the process, as are traffic control procedures in the work zone. Public participation and public information dissemination related to traffic changes are vitally important to the effective completion of a reconstruction project. Other aspects, such as the design process, including the use of 3-D and 4-D visualization, pavement renewal procedures, environmental impact mitigation and enhancement activities, that are considered in the process are also addressed.
Book Synopsis Exclusive Lanes for Trucks and Passenger Vehicles on Interstate Highways in Virginia by : Lester A. Hoel
Download or read book Exclusive Lanes for Trucks and Passenger Vehicles on Interstate Highways in Virginia written by Lester A. Hoel and published by . This book was released on 1997 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increases in heavy truck traffic on Virginia's highways in recent years have raised concerns about both safety and capacity, particularly on the interstate system. Transportation agencies have developed a number of strategies for dealing with the impacts on safety and capacity of a truck population that has been increasing in volume and in the percentage of large tractor-trailers. One strategy that has been suggested is separate lanes for trucks and passenger vehicles. A reliable methodology to determine when separate lanes for trucks and passenger vehicles are economically feasible would enable transportation officials to make informed decisions concerning when this approach should be considered and used. This study evaluated a computer program, Exclusive Vehicles Facilities (EVFS), developed by the Federal Highway Administration for determining the economic feasibility of separating trucks and other vehicles on freeway segments. A 50.7-km (31.5-mi) segment of 1-81 in Virginia was selected to demonstrate the application of the program. A number of factors contribute to the feasibility of exclusive lanes. Although no single factor predominates, traffic volume, vehicle mix percentage, accident rates, and maintenance and construction costs are given more weight than other factors in the program. Among the program's strengths are its ability to analyze a number of alternatives for a variety of different conditions, its ease of use, and the fact that it can be inexpensively applied. Its weaknesses include its inability to differentiate between the lane(s) (i.e., inside, middle, outside) to which restrictions are applied and its unsuitability for analyzing exclusive lane alternatives in which a barrier is used to separate vehicle types. With respect to 1-81, several exclusive lane strategies produced a benefit-cost ratio greater than 1.0 and a net present worth in the millions of dollars. Should 1-81 or another high-volume interstate corridor with a large truck percentage be considered for improvement, VDOT should apply EVFS to assist in evaluating the feasibility of exclusive lane alternatives. Since EVFS is designed to perform economic analyses, operational and geometric implications of any exclusive lane strategy should also be considered.
