The works will potentially include the erection of a protective cage around the Carreg Hir Standing Stone (00583w/GM170/NPRN 907226), demolition of existing buildings within the site including any grubbing up of floor slabs and/or foundations. A separate planning application is proposed for the construction of a new primary school on part of the site and the excavation of service trenches in the playing fields for installation of services to the proposed primary school block. The Glamorgan-Gwent Archaeological Trust Ltd Projects Department (GGAT Projects) have been commissioned by Neath Port Talbot County Borough Council to prepare the Written Scheme of Investigation (WSI), which provides the framework for the archaeological works. This written scheme of investigation has been produced to meet the requirements of both the protection to the SAM and demolition of existing buildings, and the erection of the new school building. There is a potential risk of encountering archaeological remains during work being carried out in the area of the new primary school as the first edition Ordnance Survey Map (1878) indicates a building, likely to be a longhouse, within the footprint of Block 1 (Figure 1). There is also a potential risk of encountering buried archaeological remains relating to the Bronze Age during works carried out in any part of the site as there is a known Bronze Age monument in the area (Carreg Hir Standing Stone (00583w/GM170/NPRN 907226)) and these features are often found as part of a larger cluster of monuments. The scheme provides for an archaeological watching brief to be carried out on all penetrating ground and demolition works in the development area. The scheme also includes contingency arrangements including the provision of sufficient time and resources to ensure that any archaeological features or finds that are discovered are properly excavated, recorded and removed; it also includes the provision for any sampling that may prove necessary, post-excavation recording and assessment and reporting and possible publication of the results. A protective cage will be erected around the Carreg Hir Standing Stone and Scheduled Monument Consent will need to be sought prior to the commencement of any works. The archaeological watching brief would also apply to any ground intrusive works on or near the standing stone. The scheme also recommends that any proposed development due to follow within the vicinity of the Carreg Hir Standing Stone (00583w/GM170/NPRN 907226) should aim to be sympathetic to its setting and a recommended exclusion zone should be put in place surrounding the monument. This can be defined further following the demolition of the surrounding buildings which may provide information on the supposed underlying burial mound. It is a suggestion that this area be used as a ‘green space’ within any proposed development so to mitigate the effect on the archaeological resource. During the post-excavation stage, archives will be prepared to the specifications in Management of Archaeological Projects (MAP2) Appendices 3 and 6, followed by a programme of analysis and research, the production of a site narrative and final report. 3 Cwrt Sart Comprehensive School, Old Road, Neath Port Talbot: archaeological written scheme of investigation A copy of the report and archive index will be deposited with the National Monuments Record, RCAHMW, Aberystwyth and the Regional HER curated by the Glamorgan- Gwent Archaeological Trust, Curatorial Division, Swansea The archaeological works will be carried out to the professional standards laid down by the Chartered Institute for Archaeologists.
