Historic building recording (HBR) is mitigation that is applied when a historic structure is to be altered or demolished. It more commonly occurs in relation to listed buildings, but it can also be applied to locally-listed or non-designated buildings. There are four levels of recording, from Level 1 (a basic visual and written record) to Level 4 (full measured survey and detailed recording and historic research). The level of detail required for the record is usually decided by the Conservation Officer or Archaeological Advisor to the planning authority.
Watching briefs are archaeological monitoring exercises which take place during the construction process.
The evaluation of a site takes place during the proposal stage of a development.
Within the development framework, excavation (also known as strip, map and record/sample) is undertaken when important archaeological sites cannot be preserved in situ.
