A Historic Building Survey provides a systematic record and assessment of historic structures that may be affected by repair, alteration, or redevelopment.

An Archaeological Watching Brief is a commonly required form of archaeological mitigation during development where groundworks may affect buried archaeological remains.

Archaeological Desk-Based Assessments (DBAs) form a key early stage in the UK planning process where development may affect heritage assets or areas of archaeological potential.

An Archaeological Evaluation is undertaken to determine whether significant archaeological remains are present within a development site and, if so, to assess their nature, extent, and significance.
