Archaeological evidences and finds, not properly detected and identified during the preliminary phase of a construction project, could lead to serious consequences during the excavation activities, such as delays to project timelines, costly redesign works or, even, bringing the entire construction site activities to a halt. These situations can be properly managed in advance, adopting effective and efficient techniques and methods to detect archaeological finds and to transform discoveries into opportunities to add value to the project.
In compliance with local legislation, Enel Green Power carries out archaeological investigations to evaluate and manage this task, combining traditional and innovative technology systems, in order to detect archaeological finds in an early stage of the construction project, and to identify areas where further detailed investigations are needed.
Archaeological finds search and survey, traditionally carried out by expert personnel, represent a considerable effort in terms of time, and they can be not compatible with project timelines, in particular when they are carried out over large areas of hundreds or thousands of hectares.
Other more innovative approaches, like the Ground-Penetrating Radar (GPR), cannot perform a detailed detection of small objects, of a few centimeters in size, located on the surface or partially buried spread on large areas with varying vegetation and soil.
Enel Green Power (EGP) is looking for non-destructive techniques to automatically detect small shallow archaeological finds (e.g. potsherds, lithic tools, bones, etc.) scattered in large areas, in order to improve efficiency and effectiveness of archaeological surveys, carried out during the preliminary phases of construction projects, to preserve the historical and cultural heritage.
Submissions should address the following Solution Requirements.
The proposed solution must:
- automatically detect different small archaeological finds (e.g. potsherds, lithic tools, bones, etc.). These small archaeological finds are characterized by different dimensions (starting from 7 mm and up to 10 cm) and they could be partially buried;
- detect different materials like pottery, stone, wood, bone, metal or any combination of them;
- be capable of analyzing thousands of hectares of area in a reduced amount of time compared with conventional and traditional techniques;
- be based on non-destructive techniques and not cause any changes and/or damage to the site or archaeological finds.
Moreover, the proposed solution should:
- be able to detect archaeological finds independently from weather conditions;
- be adaptable to different types of landscapes like, but not only, desertic areas and zones with vegetation;
- be able to analyze different type of soils like, but not limited to, clay, sand and silt.
Commercial Ground Penetration Radars (GPR) were already tested without successful results for the detection of small objects, located on the surface or partially buried spread on large areas with varying vegetation and soil. According to the above, this solution will not be considered for the present challenge.
The submitted proposal should include the following:
- Detailed description of the proposed method and/or technique, including (but not limited to):
- advantages and weaknesses of the proposed solution;
- information about the accuracy in terms of dimension and materials of archeological finds detectable and time required for the surveys execution (e.g. minimum detectable archaeological finds’ size, maximum underground depth reached, etc.);
- evidence or calculated esteem of detection probability, if applicable.
- information about its applicability (i.e. type of areas, type of soils, weather conditions)
- Data, case studies, patent and journal references or any additional material that supports the proposed solution.
The proposal should not include any personal identifying information (name, username, company, address, phone, email, personal website, resume, etc.) or any information the Solvers may consider as their Intellectual Property they do not want to share.
