Historic Building Recording and Archaeological Watching Brief 1 INTRODUCTION 1.1 Project background 1.1.1 Wessex Archaeology has been commissioned by Dynasafe BACTEC Ltd., on behalf of Dŵr Cumry Cyf (‘the client’), to produce a written scheme of investigation (WSI) for proposed historic building recording and archaeological watching brief during urgent reactive works to the Gwent SECS foul water main. The works to be monitored comprise a 0.7 km long pipeline, centred on NGR 50959 188298 (ST 50959 88298), at Black Rock Road, Portskewett, Gwent, NP26 5TW (Fig. 1). 1.2 Scope of document 1.2.1 This WSI sets out the aims of the historic building recording and watching brief, and the methods and standards that will be employed. In format and content, it conforms to current best practice, as well as to the guidance in Management of Research Projects in the Historic Environment (MoRPHE, Historic England 2015) and the Chartered Institute for Archaeologists’ (CIfA) Standard and guidance for an archaeological watching brief (CIfA 2014a). 1.2.2 This document will be submitted to the Archaeological Planning Officer, archaeological advisor to the Local Planning Authority (LPA), for approval, prior to the start of the watching brief. 1.3 Location, topography and geology 1.3.1 The proposed archaeological work is located on agricultural land to the south of the Gloucester–Newport railway line, in Porskewett, Gwent. The eastern end of the pipeline starts adjacent to the railway line, then loops southwards, crossing a disused railway cutting and Black Rock Road to the south of Aust Farm. To the west of Black Rock Road, the pipeline loops back to the west, then follows the south-west alignment of the Gloucester– Newport railway line. 1.3.2 Topographically, the pipeline is situated on slightly elevated land that overlooks the Caldicot Levels and the Severn Estuary to the east. Existing ground levels range between 8 m aOD and 17 m aOD. 1.3.3 The underlying geology is mapped as Triassic Sandstone and
