  • Investigating Unpredicted Infrastructure Failure

    This report is an outcome of PIARC mechanism for Special Projects, which is PIARC instrument to respond quickly to emerging issues for PIARC member countries. This report provides a review of 15 Unpredicted Infrastructure Failure (UIF) case studies that have been collated from around the world. For the purposes of the report UIF is defined as: instances where failure1 occurs on an asset that is considered in good condition and is well maintained The case study data from our interviews and [...]

  • Inspections and Damage Assessment Techniques - Case Studies

    The PIARC TC D.3 Bridges Technical Committee is publishing a worldwide compilation of case studies as examples for bridge owners in making critical decisions to ensure the safety of the traveling public during a bridge incident caused by damage and deterioration. This case study compilation has 28 worldwide case studies received from 15 unique countries. These case studies provide examples of incidents where owners discovered damage or deterioration under two main circumstances. Firstly, damage [...]

  • The Use of Unmanned Aerial Systems for Road Infrastructure

    From Canada to Tanzania, transportation agencies are using unmanned aerial systems (UASs), also known as drones, to collect data, design and construct road infrastructure, inspect bridges, monitor roads for avalanche and mudslide dangers, identify flood damage risks in urban areas, reconstruct crash scenes, and monitor traffic and road conditions. Public agencies, under pressure to reduce costs and to be adaptable, are turning to drones as one means of improving operations and cutting costs. Many [...]

  • Adaptation of road bridges to climate change

    Climate change has now become a global issue of concern and it is for this reason that PIARC has incorporated it into the strategic themes and technical committees for the term 2012-2015. Higher levels of carbon dioxide as part of greenhouse gas emissions are being released resulting in heat being trapped in the atmosphere, which over time will result in a rise in the earth's air temperature. This rise in temperature will filter into the oceans, causing sea water to expand and therefore raise sea [...]

  • Risk-based management of the bridge stock

    In the past, the Technical Committee 4.3 Road bridges reviewed the bridge management systems implemented in several countries and advised a revision of the management of bridges based on risks (Management of bridge stock 2011 - report ISBN 2-84060-238-5). This report aims to provide some answers with respect to risk-based management for bridges. It discusses the integration of risk-based analyses into the bridge management systems of several countries and gives examples of formal methods of [...]
