| Abstract: |
The archaeological works were undertaken in accordance with the FCCFs and LSWSI produced for the site, and in accordance with the Technical Standard: Specification for Historic Environment Investigations and relevant CIfA standards (CIfA 2014a; CIfA 2014b). All spatial setting out and recording were undertaken in accordance with the Ordnance Survey National Grid and Ordnance Datum Newlyn (ODN), as defined by the OS Active Global Navigation Satellite System (GNSS) network, and use of a virtual reference system. All interventions were located to a horizontal accuracy of ±500mm, with surface heights recorded using Real Time Kinematic (RTK) GNSS and related to PGMs. Levelling accuracy was recorded to within 10 mmÖk, where 'k' is the total distance levelled in kilometres. The survey methodology is further detailed in two survey reports: 1EW03-FUS_COP-EV-REP-CS06_CL22-000017 (Oatleys Farm) and 1EW03-FUS_COP-EV-REP-CS06_CL22-000021 (Grove Hill Farm) . All archaeological recording areas were mechanically excavated. The removal of overburden was undertaken using excavators fitted with toothless ditching buckets under the constant supervision of a suitably trained, competent and experienced archaeologist, until the first archaeologically significant horizon was reached, or when the absence of any such horizon was adequately demonstrated. Further use of mechanical excavation was only undertaken with the specific permission of the Contractor. All fieldwork was monitored by the Contractor. Excavated soil was deposited adjacent to the archaeological recording areas using mechanical excavators and dumpers. Topsoil and subsoil/overburden were stripped and stored separately Metal detectors were used by experienced staff to scan for metal finds following the mechanical stripping of the site areas and during the hand excavation of key archaeological features and deposits In accordance with the FCCFs and LSWSI, a sufficient number and proportion of features were hand excavated to meet the aims of the archaeological recording. At least 50% of the number of pits considered as part of the pit alignment were investigated, with each pit generally being subject to a 50% sample by volume and excavated to full depth. A number of pits that formed 1.6.9 Archaeological hand excavation and recording was undertaken to the general requirements as described in the GWSI: HERDS and the Technical Standard: Specification for Historic Environment Investigations. The sampling strategy was guided by the CIfA Standard and Guidance for Archaeological Excavation (CIfA 2014b) and other relevant guidance documents, as detailed in the FCCFs and LSWSI. The excavation was agreed by the Employer and the Contractor. Fieldwork Recording A sufficient sample of each feature was excavated to meet the requirements of the GWSI: HERDS. Archaeological recording included, as a minimum: • A record of the full extent in plan of all revealed archaeological features and deposits based on digital survey data, supplemented where appropriate by hand drawn records on polyester-based drawing film (at a scale of 1:10 or 1:20 unless otherwise agreed); • The written record of individual context descriptions on appropriate pro-forma recording sheets; • Single context planning used only if appropriate; • Digital photographs and other appropriate drawn and written records; and • Sections, including the half-sections of individual layers or features drawn as appropriate to 1:10 or 1:20. Archaeological recording at Grove Hill Farm (Areas C25124 and C25125) and Oatleys Farm (Areas C25135 and C25136) was undertaken separately and at different times, resulting in context and section/plan number sequences being repeated. Contexts were numbered across the excavation areas as 1–197 for Area C25124, 1–89 for Area C25135 and 100–124 for Area C25136; no features were revealed in Area C25125. |
