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.

Available in PDF, EPUB and Kindle. Book excerpt: Scope and method of study. Contract time, is the maximum time allowed for completion of all work described in contract documents. The determination of contract time affects not only the actual duration of the construction project, but also such aspects of construction such as costs, resource planning, selection of contractors and traffic problems. An accurate estimation of contract time reduces the impact of a delayed project on the local economy and provides justification to contractors during construction claims. This research performed an extensive literature review on various contract time determination procedures and systems developed and used by various state agencies to estimate contract time for their highway projects. This study surveyed 24 DOTs in the United States to determine the prevalent contract time procedures and determined their advantages and disadvantages.

This book was released on 2021-06-20 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book outlines the processes of calculating and critically reviewing construction costs and times for clients and contractors in different project phases. Any project or structural analysis should yield accurate information on times, costs, and prices. The related database is more or less uncertain depending on project complexity and the circumstances of work performance. It is thus recommended to use ranges of key input parameters. This approach consistently considers uncertainties within a holistic project view, thus enhancing the plausibility and validity of specific values. Only the integration of probabilistic methods will allow for calculating and graphically representing the chance/risk ratio as a crucial project variable ultimately influencing the entire business. This book examines the systemic modeling and consideration of uncertainties when determining construction costs and times, and life-cycle costs. It contains detailed descriptions of other decision-making processes, including project preparation and planning (developer calculation, soil survey, cost estimate), work preparation (costing, pricing, construction time evaluation, resource identification, comparison of construction methods, bid analysis, contract award), and project execution (site logistics, construction method selection, construction process planning, work coordination, sourcing, determination of additional costs, trend analyses), as well as for project portfolio management as a tool relevant to all phases.
