Snagging is a term used in the construction industry in the UK. Snagging is the production of a list of quality defects at the end of a build process/phase/stage. Typically each defect listed will carry a description of the issue, who is responsible and a target date for rectification. Snagging is carried out by the Main Contractor during the build and the responsible parties are the sub-contractors. The client for the construction project will produce a final snag list at the end of the build. Back-snagging is the term used for checking that the defects have been successfully rectified and if not the production of an up-dated snag list.
