 CBAS Evaluations
 
 
An evaluation is a cost-effective way of establishing whether archaeological remains are present on a site. The main method of evaluation is through the excavation of one or more trenches, but an evaluation could also include other techniques such as geophysics and fieldwalking.

Evaluation trenches are normally excavated using a mechanical excavator with a flat-bladed bucket under archaeological supervision, which carefully removes spits of soil until archaeological remains or the natural geology is reached. Any archaeological remains uncovered are sampled and recorded so that their character, dating and function can be determined. This will allow the County Archaeologist, advising the planners, to determine what further mitigation work will be required prior to development commencing.

If important remains are found the development may be refused or a redesign may be necessary, or a full excavation to record the remains (called ‘preservation by record’) may be required. Less important remains may be mitigated by a watching brief during the development.

A Written Scheme of Investigation (WSI) is normally required as a specification/brief for the evaluation, and once the fieldwork is completed, the artefacts recovered need to be processed and assessed and a report written on the results.
