ACSU was appointed to carry out the advance archaeological test excavations and subsequent resolution of 69 identified sites on the above road scheme between August 2015 and December 2018. The appointment included the role of PSCS for the duration of all four stages of the archaeological contract.
Over 20 km of new road in both greenfield and wetland areas was subject to test excavation and the subsequent full excavation and reporting for 64 sites confirmed a range of new archaeological discoveries, from prehistoric burnt mounds and barrow monuments to medieval metalworking sites and a post-medieval mill complex. The works also included Underwater Surveys and Architectural Heritage Surveys.
Post-excavation work included radiocarbon dating; palaeo-environmental analysis of large assemblages of wood, charcoal and plant macro-remains; osteological analysis of human and animal remains; archaeo-metallurgical residue analysis; organic residue analysis of burnt stone and specialist examination of lithics, glass, clay pipes, worked bone, pottery and ceramics.
Advanced photography methods were also applied, including Reflectance Transformation Imaging (RTI) of worked wood, UAV (drone) photography and 3D models of archaeological sites.
