Book Description
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.

Book Description
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.

Book Description
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.

Book Description
FAO and the Global Alliance of Geographical Indications (oriGin) have been collaborating since 2016 to develop the Sustainability Strategy for Geographical Indications (SSGI). This strategy for sustainable GIs aims to highlight and strengthen the relationship between GI systems and sustainability, raise stakeholders’ awareness of their role in GI sustainability and boost the sustainability performance of GI systems. Geographical indications (GIs) are signs used on products that originate from a specific territory and possess qualities or a reputation related to that origin. Through their establishment and management, GIs can stimulate endogenous development when ensuring leadership by local producers, product specifications that are tailored to local conditions and recognition by buyers of products’ origin-linked qualities. This guide provides a practical step-by-step roadmap for GI organizations that wish to engage on their own sustainability journey. The roadmap consists of three key stages: 1. prioritize sustainability topics for the GI system and engage with public and private stakeholders; 2. assess needs and establish a baseline for each priority topic; and 3. monitor and improve the GI system’s sustainability performances, and regularly review the roadmap in collaboration with allies. Communication is the fourth crucial and transversal component of the roadmap; it improves efficiency during the process and allows stakeholders to share and celebrate the results. By following the eight steps outlined in this guide, with detailed guidance, examples and models, GI practitioners will be able to design a sustainability roadmap for their GI system, together with stakeholders.
