Integration of Nondestructive Evaluation and Bridge Management Systems


Book Description

A project for the integration of nondestructive testing methods and bridge management systems is reported. The project examines the practices for inspection of bridges, the information needs of bridge management systems, and the data and assessments offered by NDE methods to develop seamless, coordinated use of NDE methods. The project delivers new definitions of condition states for commonly recognized bridge elements, a catalog of NDE methods and guidance for their use in condition rating, a review of the role of visual inspections, and a methodology for the inclusion of new NDE methods as these become available.













National Bridge Inspection Program


Book Description

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.

Element Level Bridge Inspection


Book Description

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.
