Fabricate and install permanent structures for the water environment

This standard covers the fabrication and installation of permanent structures for the water environment. Structures may include bridges, culverts, weirs, revetments, concrete fencing and coastal defences. The standard covers the actual construction of the structure and the reinstatement of the site following completion of the work.

When working with power tools or machinery you must be trained and hold current certification, where required, in line with the relevant legislation.

You must carry out your work in a way that takes account of its impact on the environment.

This standard is for those employees and volunteers working on the fabrication and installation of permanent structures suitable for rivers, coastal areas and waterways.
