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.

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.

This book was released on 2016 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The estimation process represents the critical underpinning of any project. It is a collaborative process carried during different stages. State Highway Agencies (SHAs) strive to develop an engineering estimate that is in line with the market considerations and hopefully, the low bid for the project. One important indicator of the effectiveness and accuracy of the estimating process is how closely it predicts the low bid. The problem of inaccurate SHASs' estimates is a major concern for legislators. Too low of an estimate leads to uncertainty whether the costs submitted by the contractor is fair and reasonable and should be awarded. Too high of an estimate can mean additional projects must be developed and included in the program to meet published yearly construction amounts. Accurate project estimates are critical, particularly when evaluating the reasonableness of single bids. To measure the credibility of the SHA's project’s estimate, the Federal Highway Administration (FHWA) established a degree of accuracy standard requiring the engineer’s project estimate to be within 10% of the low bid for at least 50% of the project. The Wisconsin Department of Transportation (WisDOT) has established its own level of accuracy performance standard targeting at least 60% of the projects to be within 10% of the low bid. However, WisDOT bid tabs showed a significant deviation from this desired goal. This continued performance problem resulted in WisDOT reexamining its current estimating process. WisDOT requested that the Construction and Materials Support Center (CMSC) at the University of Wisconsin-Madison assist the Department in the improvement of the accuracy its current estimates. First, WisDOT requested CMSC to look at the project level and improve the engineering estimate accuracy (EEA). In an attempt to achieve the desired objective, the research team analyzed the WisDOT bid tabs at the contract level and created regression models to improve the accuracy of the engineer’s estimate. The underlying concept is dependent on improving the engineer's estimate by predicting the lowest bid for the project. However, the various statistical analyses performed and the various models formulated to improve WisDOT EEA did not boost the EEA to the 60% threshold. One reason for these results is that the engineer's estimates themselves contain a high degree of noise or hidden variables such as the number and experience of the personnel who develop the estimates. Thus, inaccuracy of the cost estimates stem not only from the engineer's estimate. This paper presents the results of this analyses. Following these results, WisDOT requested the research team to expand the research and look at the construction cost index (CCI) as a potential tool for improving the estimating process. CCIs are important SHA to provide an indicator of construction cost escalation over time and to update old bid cost information to current year pricing. FHWA publishes a National Highway Construction Cost Index (NHCCI) based upon cost data from several states for SHA to use. WisDOT uses a CCI to measure the changes in purchasing power of their construction dollar from one year to the next. Currently, WisDOT uses a fixed-weight index to compute the CCI for a fixed basket of seven construction items. However, the current WisDOT CCI is subject to considerable short-term variation and does not accurately reflect the project bid costs that the department is experiencing. This paper presents results of the study requested by WisDOT to develop an approach for calculating a more representative, reliable and objective CCI. The paper presents various approaches to calculating a CCI, highlighting their properties and characteristics. It also outlines the process used to select a representative basket of items to calculate the index and outlines the data preparation steps needed to improve data quality. The recommended methodology uses a chained, two-stage aggregation computation process. The paper compares the newly constructed WisDOT CCI to the old CCI as well as to the NHCCI. The impact from selecting different size baskets of items is also investigated and it is concluded that a basket containing a representative number of items is sufficient to calculate a reliable CCI. Finally, the research team developed time series models to accurately forecast the CCI.
