Available in PDF, EPUB and Kindle. Book excerpt: Provides the results of an audit of the Fed. Hwy. Admin. (FHWA) to improve its oversight of states¿ bridge inspections, load ratings, and max. weight postings. FHWA should encourage states to use more detailed data to manage their bridge programs. Shortly after the I-35W bridge collapse in Minneapolis, MN on Aug. 1, 2007, killing 13 people, the Sec. of Transportation asked whether FHWA¿s Nat. Bridge Inspection Program delivered the highest level of bridge safety. Objectives for this audit were to evaluate FHWA¿s: (1) implementation of data-driven, risk-based oversight to target bridge safety risks most in need of attention, particularly those related to load ratings and postings; and (2) promotion of state use of bridge management systems.

Book excerpt: In 2012, Congress passed the Moving Ahead for Progress in the 21st Century Act (MAP-21) and committed to the development of a data-driven, risk based approach to asset management in the United States. This law requires the collection and submission of element level bridge inspection data for all National Highway System bridges, in addition to the National Bridge Inspection condition rating data. Ultimately, the data collected during element level bridge inspections should satisfy the requirements of the Federal Highway Administration and MAP-21 and be utilized by INDOT to evaluate bridge condition, predict deterioration, and guide decision making. The objective of this project is to develop recommendations for element level bridge inspection techniques, data collection, and inspector training based on a survey of INDOT peer agencies and a literature review of existing research and bridge inspection guidance. In order to collect consistent and reliable data, a rigorous inspector training program and detailed quality control procedures are necessary. INDOT must provide inspectors with the tools to be successful, including clearly defined expectations and instructions, comprehensive training and technical support, and effective inspection equipment. Similarly, robust quality control measures and periodic performance testing should be implemented to improve inspection quality and assess the agency's performance.

Book excerpt: The Guide Manual for Bridge Element Inspection builds on the element-level condition assessment methods developed in the AASHTO Guide for Commonly Recognized Structural Elements, which it replaces. Improvements have been made to fully capture the condition of the elements by reconfiguring the element language to utilize multiple distress paths within the defined condition states. The multi-path distress language provides the means to fully incorporate all possible defects within the overall condition assessment of the element. The overall condition of an element can be utilized in this aggregate form, or broken down into specific defects present as desired by the agency for Bridge Management System (BMS) use. The Bridge Element Inspection Manual provides a comprehensive set of bridge elements that is designed to be flexible in nature to satisfy the needs of all agencies. The complete set of elements capture the components necessary for an agency to manage all aspects of the bridge inventory utilizing the full capability of a BMS -- Publisher's website.

Available in PDF, EPUB and Kindle. Book excerpt: This synthesis reports bridge inspection practices in the United States and selected foreign countries. The synthesis is a collection of information on formal inspection practices of departments of transportation (DOTs). These are primarily visual inspections and they provide data to bridge registries and databases. For U.S. inspection practices, this synthesis reports on inspection personnel, inspection types, and inspection quality control and quality assurance. Staff titles and functions in inspection programs are reported, together with qualifications and training of personnel, formation of inspection teams, and assignment of teams to bridges. Inspection types are described in terms of their scope, methods, and intervals. Quality control and quality assurance programs are reviewed in terms of the procedures employed, staff involved, quality measurements obtained, and the use of quality findings in DOT inspection programs. Foreign practices are presented in the same organization of inspection personnel, types, and quality programs. Comparisons of U.S. and foreign inspection practices are included. Information was obtained from a questionnaire sent to U.S. state transportation departments, similar questionnaires modified individually for transportation agencies in selected foreign countries, and formal documents used by transportation departments and agencies. These documents primarily included bridge inspection manuals, inspection training manuals, and technical memoranda, but also included blank forms for inspections, DOTs job descriptions for inspectors, and descriptions of inspection training courses. Overall, this synthesis includes information from forty U.S. state transportation departments and from roads agencies in eight foreign nations (Denmark, France, Finland, Germany, Norway, South Africa, Sweden, and the United Kingdom). The synthesis also includes, in an appendix, information from a few provincial and municipal transport agencies in Canada.

Download or read book Assessing National Bridge Inspection Standards (NBIS) Metrics Using Data Extracted from National Bridge Inventory Source Files written by Scott McClure and published by . This book was released on 2013 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transportation agencies face significant challenges in the maintenance, repair and operation of the nation's bridge infrastructure as these structures continue to age and deteriorate. Compounding the issue is a chronic lack of adequate funding to perform recommended improvements, an increase in the frequency and magnitude of oversized commercial vehicles, and a dramatic reduction in the number of bridges built or reconstructed over the last decade. In response to a USDOT audit recommending the Federal Highway Administration (FHWA) develop and implement minimum requirements for data-driven, risk-based bridge oversight during FHWA annual National Bridge Inspection Standards (NBIS) compliance reviews improve, and to develop a comprehensive plan to routinely conduct systematic, data-driven analysis to identify nationwide bridge safety risks for remediation in coordination with the States, FHWA identified twenty three (23) specific metrics to assess states compliance with National Bridge Inspection Standards (NBIS) requirements and to identify potentially at-risk structures using a data driven approach. These metrics were implemented in 2011 and revised in 2012. This paper presents the results of efforts by the New Mexico Department of Transportation to refine a prototype bridge information system developed in 2010 to include a simplified means to query data contained in the National Bridge Inventory Database and to provide the means to prepare reports and randomized lists of bridges in categories related to these metrics to assist federal oversight personnel in assessing state compliance levels and recommending follow-up actions.

Available in PDF, EPUB and Kindle. Book excerpt: The New York State Department of Transportation (NYSDOT) maintains an inventory of over 17,000 highway bridges across the state. As per New York State's Uniform Code of Bridge Inspections, all bridges in New York State are inspected biennially, or more often as necessary. Bridge inspectors are required to assign a condition rating for up to 47 structural elements of each bridge, including 25 components of each span of a bridge, in addition to the general components common to all bridges based on visual inspection of these elements. The bridge condition rating scale ranges from 7 to 1, 7 being new and 1 being in failed condition. In addition to this, ratings 8 and 9 are assigned to cases "not applicable" and "condition and/or existence unknown". The objectives of this research have been to (1) conduct a detailed evaluation of the consistency of inspection ratings, and (2) provide recommendations for improvements to bridge inspection procedures and training to improve consistency, whenever possible. A broader outcome of the research has been the development of knowledgebase [sic] on factors affecting consistency of bridge ratings. These research objectives have been achieved through a detailed and comprehensive literature review on inspection practices and the NYSDOT bridge inspection program and, development and evaluation of consistency of the bridge inspection ratings through the inspection of 4 selected bridges by 21 inspection teams. Numbers of bridges and inspection teams have been selected to generate statistically sufficient data for the evaluation of consistency of inspection of different bridge elements. A detailed and quantitative evaluation of consistency of inspection ratings of different bridge elements has been carried out through the analysis of inspection data. Results show that the overall consistency of ratings of different elements is more than 90%.

Available in PDF, EPUB and Kindle. Book excerpt: A large percentage of bridges in the state of Iowa are classified as structurally or functionally deficient. These bridges annually compete for a share of Iowa's limited transportation budget. To avoid an increase in the number of deficient bridges, the state of Iowa decided to implement a comprehensive Bridge Management system (BMS) and selected the Pontis BMS software as a bridge management tool. ... The objective of this work was to develop an automated-computerized methodology for an integrated data base that includes the rating conditions as defined in the Pontis program.
