Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to highway administrators; design, construction, and specification engineers; project schedulers; and highway construction contractors. The synthesis describes the state of the practice with respect to procedures used throughout the United States and other countries to determine highway construction contract time, with emphasis on new methods in use. Transportation agencies must set reasonable times for completion of construction projects. Factors to be considered in determining contract time include materials, equipment, labor, cost, and constraints such as weather, traffic conditions, utilities location, and user convenience. This report of the Transportation Research Board covers the still pertinent procedures from NCHRP Synthesis 79: Contract Time Determination (e. g., critical path methods, linear scheduling, bar charts) as well as new methods in use (e.g., A + B methods, lane rental, flexible time-to- start). In addition to information on various methods to determine contract time, information on issues related to implementing procedures for contract time determination, from both agency and contractor perspective, is included.

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.

This book was released on 2017 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Production rates are significantly important for contract time determination procedures as these are essential for estimating the duration of every activity needed to complete a highway construction project. For this reason, many estimation systems, including Texas Department of Transportation’s Contract Time Determination System (TXCTDS), explicitly depict production rate data of work items considered important in highway construction projects. Though many systems and databases available in the public domain provide an abundance of production rate data, they provide different rates for comparable work items. This research focusses on the development of the Production Rate Resource, a single, easy to use reference of production rate data gathered from publicly available sources intended to be used by TXDOT contract time estimators. The resource was developed by gathering production rate information through conducting a literature review and organizing the found data into a well assembled Excel workbook. This arrangement contains Excel sheet tabs depicting the resource’s introduction, details of the included production rate sources, a summary of the included work items and their respective production rate data, and item worksheet tabs portraying the gathered production rate data for each work item. These item worksheets also contain production rate averages, graphs that allow comparison and analysis of the data through visual aid, and specific scope information provided by the original sources. A recommended process based on the critical path method (CPM) was also developed for conducting a contract time determination using the Production Rate Resource. The gathered production rate data was then tested by conducting two contract time estimations of actual TXDOT highway construction projects using the recommended process. The results were compared with TXDOT’s contract estimations for an in-depth analysis, and the findings led to significant improvements to the resource. The final assembly of the Production Rate Resource provides production rate data for 59 highway construction work items provided by six publicly available sources.

This book was released on 2004 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes a process for estimating the construction contract time for highway projects. The process developed uses the critical path method (CPM) to assess complex, non-repetitive construction items, while at the same time, assessing horizontal, repetitive construction items with the linear scheduling method. This is chiefly done by the identification of strategic sequencing options and critical-path-limited scoping of the model.

Available in PDF, EPUB and Kindle. Book excerpt: Excessive contract time is costly because it extends a construction crew’s exposure to traffic, prolongs the inconvenience to the public, and subjects motorists to less than desirable safety conditions for longer periods. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 298: Developing a Systematic Approach for Determining Construction Contract Time seeks to provide a systematic approach for determining construction contract time for a wide spectrum of highway projects. The document is supplemental to NCHRP Research Report 979:Systematic Approach for Determining Construction Contract Time: A Guidebook.

This book was released on 2017 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Establishing contract time is an important part of the highway project development process. Contract time directly impacts project costs, the public, and risk for contractors. This synthesis documents current methodologies and procedures used in state transportation agencies to estimate contract time for various highway project delivery methods. Information used in this study was gathered through a literature review and a survey of state transportation agencies. Follow-up interviews with selected agencies provided additional information. Timothy R.B. Taylor, Roy E. Sturgill, Jr., and Ying Li, University of Kentucky, Lexington, collected and synthesized the information and wrote the report. The members of the topic panel are acknowledged on the preceding page. This synthesis is an immediately useful document that records the practices that were acceptable within the limitations of the knowledge available at the time of its preparation. As progress in research and practice continues, new knowledge will be added to that now at hand."--PDF page 5.
