Archaeological monitoring of all groundworks as specified in the project brief and WSI. Approximately 39m of foundation trench was machine-excavated under the supervision of a CAT archaeologist. The trench for the eastern extension was 0.6-0.65m wide by c 1.25m deep and for the northern 0.65-0.7m wide by c 1.55m deep. All trenches cut through topsoil (L1, c 0.3-0.4m thick) and subsoil (L2, c 0.25-0.4m thick) into natural (L3, encountered at a depth of between c 0.58-0.80m). Archaeological monitoring was carried out at 'Valcot', London Road, Chelmsford, Essex during the construction of extensions to the property. Despite being located within an area of archaeological potential, no archaeological deposits were identified during the works.
