Available in PDF, EPUB and Kindle. Book excerpt: Costs of highway construction projects have been rising with rising prices of construction materials such as asphalt, concrete and steel. Identifying cost saving strategies is one of the ways of efficient utilization of available funds (federal and local) by the state Department of Transportations (DOTs) and Local Public Agencies (LPAs). A case study comprising of a sample pair of projects (a federal-aid project and a 100% locally funded project) constructed in Elkhart County, Indiana was undertaken to compare construction costs when sources of funding vary. Based on analysis of cost details from these two projects and discussions with the general contractor involved with these projects and other contractors in Indiana, possible reasons of cost differences between the projects were identified. Pavement evaluation tests were conducted to compare the pavement conditions of the road sections built under the two sample projects. This report presents some observations regarding cost differentials between federally funded projects vs. 100% locally funded projects, and provides some suggestions for future investigation and study.

This book was released on 2009-03-01 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted to develop methodologies for appropriately determining the monetary values of I/D rates of highway construction projects in Indiana. In this study, a comprehensive literature review was performed to identify possible effective methodologies for work zone effects, construction impacts, and contract time optimization. The highway production rates were developed in a previous study. The production rates were validated and adjusted with the help from INDOT field engineers. The weigh-in-motion (WIM) collected traffic data were obtained, processed, and analyzed to provide input data for user cost calculations at highway work zones. Construction data were obtained and processed to develop the relationship between the construction cost and construction time. With the traffic and construction data, the methods for user cost calculations were developed as the basis of determining appropriate I/D rates. User costs resulting from traffic delays at Indiana highway work zones were analyzed. A series of equations for estimating user costs at work zones were developed. User cost calculation sheets using MS Excel were developed based on the traffic data on Indiana highway network. Finally, a method was developed to determine I/D rates based on the relationship between construction cost and construction time in combination with the estimated user costs at given work zones. Guidelines for developing A+B bidding and I/D provisions were provided.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The Construction industry, which can be in the form of residential building, commercial, public and utility buildings, or civil engineering building, has a huge influence on any nation’s economy. Its influence can be either manifested in its contribution to the economy or the service it provides to the community. In order to build any infrastructure project with a balanced cost, time, and quality, project managers search for alternatives that can satisfy these contradicting attributes. The traditional time-cost trade-off was enhanced with the three-dimensional time-cost- quality optimization in the last two decades. The optimization is aimed to minimize the time and cost as much as possible while increasing the quality of the infrastructure to be built. The issue of financing in developing countries has been a bottle neck of success in constructing infrastructure like highway. Many researchers have concluded in their studies the causes of time and cost overrun in high-way construction were, contractors’ financial problems, Inflation, progress payments delay by owner, political issues, variations, lack of managemental skills, cost fluctuation of materials during construction, environmental issues, Shortage in equipment, Inadequate contractor experience etc. The number of studies in the literature that deals with financial optimization and cash-flow analysis to address the problem of financing and inflation are getting more attention. The cash-flow analysis and maximum overdraft to be paid give a good indication to the main participants about the trends toward cost and time overrun. They can also help in making a proper decision right at the beginning. The purpose of this study is to deal with the optimization of time and profit of highway constructions taking in to consideration the amount of available credit and future value of the cost of each activity and cash-flow analysis in a comprehensive model. This type of analysis gives the contractor how its profit will be influenced with his allowable credits and the time associated with it. Besides, the model also generates a line of balance scheduling for the project as highways are among the repetitive projects. The cash-flow analysis gives extra information on the overdraft so that it can be optimized to find good combination of execution of the activities which will minimize the overdraft, interest paid to banks and most importantly maximize the profit to be gained by the project using GA approach. This type of analysis also gives alternatives for contractors how much profit would they like to gain by providing different amount of credits. At first the profit and time are optimized individually to get the maximum profit and minimum time for completing the project. Then the multi-objective optimization using goal programing takes place which tries to minimize the deviation from the optimum individual values by assigning importance weight to the individual objectives to find the near optimal solution. The model is tested for different allowable credits and its sensitivity analysis outcomes are plotted to see the relationship between the allowable credits and the profit. To validate the efficiency of the developed model, it is applied to a project from the literature that addresses scheduling and cost optimization of repetitive projects. It is found that the outcome of the model that maximizes the profit and minimizing the time outlooks the results of the literature with 4.65% and 0.38% improvement in duration and cost of the project respectively.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Pursuant to a legislative requirement, GAO provided information on the equipment rental rates states use to reimburse contractors for unanticipated work on federal-aid highway projects, focusing on: (1) the basis on which states establish equipment rental rates; (2) whether states establish rental rates that are appropriate with contractors' actual equipment costs; and (3) whether the Federal Highway Administration (FHwA) adequately oversees states' use of rental rate guidelines. GAO found that: (1) of the 52 departments of transportation that use a standard rate guide to determine equipment rental rates, 47 use national standard rate guidelines, 3 use published guidelines from external sources, and 2 have developed their own rate guides; (2) although the California Department of Transportation (Caltrans) has taken steps to lower its rates, its rates remain 10 percent higher than national standards because its equipment rental rate guidelines are not based on national standard rates and include unallowable costs; (3) 28 of 52 departments of transportation improperly established their equipment rental rates because they failed to follow FHwA guidelines, adhere to required methodologies, or fully account for duplicative overhead cost factors; (4) FHwA has allowed duplicative overhead costs to be paid by federal funds because its staff is not familiar with standard rate guidelines; (5) FHwA oversight of states' use of rental rates is inadequate because its rental rate guidance is not incorporated into highway program and policy manuals, guidance on contractor discounts is insufficient, review of rental rates is not systematic and consistent, and its field offices are not told of potential problems; and (6) FHwA inattention to rental rate policy guidance and rate-setting methodologies has resulted in higher costs and inequitable treatment of contractors.
