Whether above or below water, the requirements of structural inspection are the same; to obtain an accurate record of the existing condition. As well as structural deterioration, specific potential problems relating to submerged structures such as scour, erosion and accelerated local corrosion problems also need to be checked.
The preparation of the inspection report will often be undertaken by an engineer who may not have an in-depth knowledge of underwater inspection techniques. This publication provides advice to engineers, their clients and supporting contractors so that inspections are conducted in a safe manner and provide accurate and meaningful information at reasonable cost. It is therefore essential reading for anyone likely to be involved in such inspections.
Current practice for undertaking inspections of underwater, inland and coastal structures in water depths of up to 30m (including inspection techniques, equipment and safety) are examined. Provisions of the Diving at Work Regulations 1997 and the associated Approved Code of Practice (ACOP) are also taken into account. Individual chapters consider:
Reporting Appendices provide a bibliography, a list of terms, advice on the design of limpet dams, and typical forms used in the overall process. The Institution also gratefully acknowledges the sponsorship provided for this report by the Environment Agency, the Highways Agency, British Waterways and Defence Estates. While it is intended that the contents of the report reflect current UK practice, input has been provided by corresponding members of the task group, and others, in South Africa, Jamaica and Australia.
