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.

Download or read book Contract Time Optimization Methodologies for Highway Construction Projects written by Yi Jiang and published by Purdue University Press. 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.

Download or read book Construction Schedules Analysis Evaluation and Interpretation of Schedules in Litigation and Dispute Resolution 4th Edition written by Michael T. Callahan and published by Juris Publishing, Inc.. This book was released on 2011-06-01 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fourth Edition of Construction Schedules examines the use of construction schedules in resolving disputes over contract time extensions and the economic consequences of such, and takes an in-depth look at the only lasting opinions that count in this litigious arena. These opinions are the ones expressed by the United States court system and other third party neutrals across the world. Construction schedules are now globally used and analyzed to establish and prove opposing positions when projects are completed later than promised, occurrences that are attributable to a multitude of causes during the construction process. Entitlement to equitable adjustments due to changed conditions is now argued across the globe and American court opinions are the linchpin landmarks for neutral decision makers. The current edition of Construction Schedules reflects the current thinking of the courts and suggests how parties and their attorneys should prepare and proceed in litigation, arbitration, or mediation. For anyone involved or potentially involved in construction schedule litigation and/or dispute resolution, this work is the required starting point and reference.

Download or read book Towards the Determination of the Construction Contract Duration for Building Projects Prior to the Bidding Stage written by Ziad Abdul Monem Chehade and published by . This book was released on 2005 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Construction duration is defined as the time frame given by the owner for the contractor to complete the project under normal work conditions, normal construc tion practice, and consistent with reasonable limits on costs. It starts when the con tractor receives the instruction to proceed and ends at the completion of construction w orks on site, allowing for delays caused by unanticipated circumstances, such as change orders, extra works, supply of materials, location, weather, and site work conditions. A single and deterministic approach for setting and analyzing construction contract duration may not be suitable in today?s dynamic and complex project environment. Previous researches were studied, the problem was framed and?a construction duration checklist? was developed to identify the different factors and factor c ategories affecting construction duration such as site requirements and considerations, fa cility requirements and considerations? In addition, the duration was broken down into controlling phases and sequential lags, and methods for estimation were provided . Forecasting construction duration is generally a subjective practice based on planners experience and judgment. This project is an attempt to provide a more objective approach for determining a proper duration to allow for the contractor to complete the project. Consequently, the contractor could prepare realistic and p ractical detailed schedule at the allocated budget within the limited time frame.

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.

Download or read book Development and Application of a Production Rate Resource for Contract Time Determination written by Roberto Leandro Oramas and published by . 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.
