The above ground structure of the buildings were demolished prior to the start of the archaeological monitoring. Subsequently, the removal of the concrete slabs forming the floor of the buildings were removed with a 360� excavator under the supervision of an archaeologist. The resultant rubble was only partially removed from within the footprint of the buildings. No additional invasive groundwork was carried out. Due to the presence of asbestos in the demolished structures, no hand-cleaning of deposits was carried out. Standard John Moore Heritage Services techniques were employed throughout, involving the completion of a written record for each deposit encountered. A photographic record was also produced. The archaeological monitoring and recording aimed to investigate the presence of later Prehistoric (Iron Age) and Romano-British remains at the site. However, during the course of the excavated works, no archaeological deposits or features were observed. This is likely due to the severe truncation caused by the construction of the now demolished modern-brick buildings.
