Excavation Controlled archaeological excavation has been the core of TPA’s activities for over 40 years. Small to large, urban to open-area rural - TPA has unrivalled local expertise.
Geophysical Survey Geophysical survey is a non-invasive remote sensing technique, allowing us to ‘see beneath the soil’. TPA can undertake resisitivity (earth resistance) and magnetometry (fluxgate gradiometry) surveys.
High Definition Survey Laser scanning and HDR photography is revolutionising the recording of cultural heritage. Millimetre accuracy, high speed and stunning visuals - TPA is at the forefront of this exciting field.
Written AssessmentsTPA can provide Desk-based assessments, Environmental Impact Assessments, Historic Area Assessments, Heritage Statements, Written Schemes of Investigations and Project Designs.
Community Archaeology TPA has decades of experience working with local groups and local people. We aim to inform and empower - it’s your archaeology!
Building RecordingBuilding recording and analysis to English Heritage and RCHMS standards, medium format and HDR photography, metric survey and laser scanning.
Field evaluationEvaluation of possible archaeological deposits in the field will save money in the long term. Techniques include fieldwalking, boreholing, test-pitting and trial trenching.
Environmental Services We do environmental processing.
Resource Management We do resource management and large-scale research projects.
Advice and Assistance We offer specialist advice on possible archaeological planning issues.
Post-excavation Services TPA can offer specialist post-excavation services including finds analysis, assistance with publication, experimental archaeology and more.
Watching BriefsDuring a Watching Brief an archaeologist monitors ongoing groundworks for surviving deposits of archaeological interest. This can be very cost-effective for smaller developments.

TPA has always understood that archaeology is only as important as the interest that people show in it, and we work hard to ensure that local communities share in our work. As well as giving hundreds of talks to local societies over the years, and teaching to University students and local groups, TPA regularly incorporates volunteer input into our work. Sometimes this is in the form of individuals working on site with us, sometimes with post-excavation work such as finds-washing and cataloguing, and sometimes with full-scale community excavations. Recent large-scale excavations with major community involvement have included open-area rural work at Girton quarry and Langford quarry in Nottinghamshire, and excavation of Second World War remains at Wollaton Park Nottingham.If you'd like to volunteer to help, see our Volunteering page.
High-definition survey by laser scanning (terrestrial lidar), coupled with high dynamic range digital photography, allows TPA to record and visualise cultural heritage at speeds and levels of detail not previously possible. TPA owns a Leica HDS6100 laser scanner capable of recording 500 000 3D points per second, at an accuracy of +/-2mm or better. This equipment, coupled with digital HDR photography and GPS/total station georeferencing, can be used to record everything from carved stones to whole landscapes.The range of possible products and deliverables from laser-scanned surveys is broad - raw 3D point cloud data, photorealistic point clouds, rendered still images, animated videos, sections and slices, contour plans, DTM/DEMs, building elevations, drawn CAD illustrations, 3D meshes, 3D models for SketchUp, Rhino, Maya or 3DS Max. In fact almost anything from a 2D line drawing to a full 3D explorable environment is possible.If you haven’t seen what laser scanning data can do for your site, have a look at our YouTube site and the Nottingham Caves Survey website, or contact Dr David Strange-Walker on 0115 9514 828.
TPA has extensive experience of geophysical survey in the Trent Valley and further afield.Small areas can be economically and manually surveyed by Resistivity (also called Earth Resistance) or Magnetometry (also called Fluxgate Gradiometry). Resistivity is the slowest technique in the field but is extremely good at identifying small archaeological features. Magnetometry (often coupled with a rapid Magnetic Susceptibility survey) is much more rapid and is particularly good at identifying evidence of burning and thus human activity.For large area surveys TPA chooses to use the GEEP system, with an array of extremely sensitive caesium magnetometers towed on a sledge and located by GPS. This can provide very rapid and economical surveys - several hectares can be surveyed in a single day.In 2007 TPA completed a major English Heritage-funded research project assessing the effectiveness of geophysics in the East Midlands. A copy of this survey in PDF format can be downloaded here.The success of a survey and choice of appropriate technique depends on the geology and topography of each individual site. Contact Dr Paul Johnson to discuss your requirements.
An archaeological Watching Brief is often specified by a local government Development Control Archaeologist if the possibility of damage to surviving archaeological deposits is relatively low. During a watching brief the developer conducts the site groundworks as normal but a archaeologist will be present monitoring the works. The archaeologist will wish to record the presence or absence of surviving archaeology.TPA has many years experience working on site with developers large and small. Our staff are CSCS certificated to work on construction sites and have an impeccable safety record. We also understand that time is money and work hard to ensure a minimum of distruption on site for archaeological recording.
Local government Development Control Archaeologists may insist that field evaluation of archaeological deposits takes place before development is allowed. The goal of this work is to establish on the ground the quantity, location and extent of archaeological remains that survive. Evaluation may lead to further excavation, to a Watching Brief, or may well conclude that there is no need for further archaeological investigation.FieldwalkingIn arable fields archaeological artefacts (especially flint tools, pottery and metalwork) may be ploughed up and can be systematically collected from the ground surface. Mapping the density and character of these finds can identity and date settlement patterns.BoreholingDrilling systematic boreholes or manual auger-holes can determine the depth of archaeological deposits and also locate waterlogged or possible palaeoenvironmental materials.Test-pittingTestpitting is a method of establishing depth, character and extent of archaeological deposits through the systematic excavation of a number of small (usually 1m x 1m) test-pits. This technique is most commonly used in rural areas. Test pits are usually dig by hand and cause little long-term impact.Trial trenchingThe excavation of one or more trial trenches, often targeted following geophysical survey, can most accurately determine whether archaeological features and deposits survive. Trial trenches are often dug by machine and then cleaned and recorded by hand.
