The fieldwork followed the methodology set out within the WSI (CA 2019). An archaeologist was present during intrusive groundworks comprising two test pits and four boreholes. An archaeological watching brief was undertaken by Cotswold Archaeology during groundworks associated with geotechnical investigations as part of the proposed A417 Missing Link scheme at Birdlip, Gloucestershire. No features or deposits of archaeological interest were observed during groundworks, and no artefactual material was recovered.
