Maintaining our bridge stock - risk based inspections

The importance of a regular schedule of bridge inspection, usually annual or biennial, is emphasised. In recent years the understanding of deterioration mechanisms has increased which has enabled engineers to focus more attention on the vulnerable parts of a bridge. Research undertaken for the Rail Safety and Standards Board, UK has investigated how inspection regimes can be tailored to suit different bridge types. Those that deteriorate more rapidly would be inspected more frequently than those that have slower deterioration rates. The more amenable a structure is to examination, the earlier the defect is likely to be picked up by the examination regime and the greater the scope for extending the interval between examinations. The development of a mathematical model for the determination of inspection interval is described.
