Archaeological evaluation enables the rapid determination of the presence or absence, nature and extent of archaeological remains on a site. An evaluation can consist of one or a combination of differing methodologies. These might include non-intrusive techniques such as landscape or geophysical survey, but more usually take the form of trial trenching, carried out across the footprint of the proposed redevelopment. Whatever the method of evaluation, Pre-Construct Archaeology can design, undertake and manage a suitable evaluation strategy on behalf of our clients.

Should trenching be required, the number and size of trenches normally varies from site to site, but usually comprise between 4% and 10% of the footprint area. Pre-Construct Archaeology can negotiate the methodology with the local planning authority on our client's behalf.

The results of the evaluation are used to advise the planning authority on the character, extent and importance of archaeological remains. As such it is crucial that developers can trust the ability and experience of the organisation undertaking this type of work.
