PCA offers a wide range of measured survey and landscape investigation services. We are able to undertake fieldwork on monuments, sites and landscapes in both urban contexts and rural areas, using a range of traditional and technological techniques as appropriate to the accuracy, scale and final output with cost and efficiency in mind. We offer:
- Measured survey (TST/GNSS/Laser scanning)
- Landscape setting through observation, survey, aerial photograph and LiDAR interpretation, historic map and documentary research
- Analytical earthwork survey (graphical/TST/GNSS, resulting in traditional hachured plan or DTM)
- Geospatial imaging (photogrammetry/Structure-from-Motion/scanning)
- LiDAR and laser scan point-cloud data processing and visualisations
- Advice on recording methodologies for different site-types and levels of recording
- Landscape investigation of sites, monuments and landscapes from rapid assessment to detailed field survey, analysis and interpretation
Topographic, contour and landscape surveys can be supplemented by a range of geophysical techniques, such as resistivity, magnetic susceptibility or ground penetrating radar, which are predictive tools designed to investigate below ground level.
The comprehensive service provided by Pre-Construct Archaeology will integrate the results of survey as part of a complete archaeological package developed in consultation with our clients and tailored to suit the requirements of each project.
Various types of surveying techniques are used to investigate, identify, analyse, record and interpret the historic environment. Survey is essential in providing the knowledge and understanding required for making effective management decisions.
Survey work may be required in response to the recommendations of a Conservation Management Plan, Environmental Impact Assessment or Historic Landscape Assessment. It is also used for the recording, analysis and interpretation of historic sites, landscapes, buildings and monuments.
Types of survey undertaken by PCA are site set-up and recording, topographical survey, earthwork survey, building recording and landscape assessment. PCA’s team are equipped with the latest technology in survey instruments and software.
Examples of Our Survey Work
- Topographical survey to provide a geographical context, aid understanding and interpretation of a site or its components’ location;
- Urban townscape assessment and recording;
- Parkland surveys to understand the development of the park and record earlier activity in the form of deserted settlements and agricultural vestiges;
- Large scale recording providing full detail and analysis of earthwork features;
- Archaeological survey of gardens to record extant and lost features and identify past phases in the garden’s development;
- Small scale recording and rapid assessments of large areas of landscape;
- Integration of features into their landscape, working together with the building recording and photography teams;
The results can be provided as raw or processed data, as CAD drawings or as part of a GIS. Additional work may be carried out in the form of documentary research and map regression, in order to provide a full analysis and interpretation in the form of a report, which may lead to a publication.
