Damage assessment and conservation of underground space as valuable resources for human activities use in Italy and Japan

  1. 1. Damage assessment and conservation of underground space as valuable resources for human activities use in Italy and Japan CNR-JSPS Bilateral program 2018-2019 Roberta Varriale varriale@issm.cnr.it This work is licensed under a Creative Commons Attribution-NonCommercial 4.0 International License

  3. 3. Underground space and the management of aboveground urban conflicts • Environmental and urban history • Natural and social conflicts • Sustainable urban development • Long period • Cultural heritage valorization, green-economy, risk management and smart cities planning
  4. 4. UNDERGROUND BUILT HERITAGE (UBH) The complex of underground artifacts caved in the past to manage urban functions and now significant part of local cultural heritage
  5. 5. All phases of the decisional process: • Selection of sites • Individuation of the most suitable reconversion practice according to the historical use • Preservation and safeguard of the comunicative value within the reconversion What is the role played by historical classification within the reconversion planning?
  6. 6. Urban history approach, the projects: • Undergrounds in Naples • Underground in Europe • Undergrounds in the Mediterranean • Bilateral agreement Italy-China • Comparative study Italy-Algeria
  7. 7. 3 different levels of action for UBH regeneration • cultural heritage itself: monitoring, communication of historical functions, restoration, fruition as a cultural site (installations of technological instruments to diffuse the underground culture, reconstruction of underground life) • same functions as in the past: the historical sites restored and used again according new parameters (productive spaces reinvented according to the contemporary standards, sustainable living) • new functions: the sites are restored and new functions are located but the communicative role is preserved (shops, hotels, restaurants, urban facilities in pre-existent underground spaces)
  8. 8. Italy-Japan Case study: Naples and Matera • Visit 2018: NAPLES • Visit 2019: MATERA
  9. 9. Naples is known as the underground city • Greek settlers used yellow tuff to build the city, reconverted caves in cisterns, built the first aqueduct “the Bolla” and caved their necropolis extra moenia. • Romans built the second aqueduct, “the Claudio”, the catacombs of San Gennaro and thermal facilities. • During Middle ages new necropolis were built and dismissed caved were used as wheat and oil deposits. • During the Spanish domination the importation of building materials from outside was forbidden for demographic reasons and the citizens started caving in the city subsoil to build: underground became the negative face of the aboveground city. • Dismissed caved were used as collective burial places during epidemics till XVIII Century. • During XIX Century dismissed caves supported local economy • During Second World War, underground networks were used as bunkers

  15. 15. Monitoring case study: Via Posillipo 26 caves
  16. 16. Matera: the CAVED CITY Sometimes the underground experience was extreme … • Underground was the place for urban development itself • The idea of negative building culture was used in Matera in order to face and solve adverse social and climatic conditions: Strong annual temperatures ranges Plateau Water scarcity

  21. 21. Monitoring the risck (Marco Leo): Naples case study: coastal cave in Via Posillipo First acquisition Second acquisition
  22. 22. Point cloud comparison A region in the cloud with substantial metrical differences along two acquisition sessions. Differences have to be pointed out if they lay outside the intrinsic sensor uncertainty.
  23. 23. Using the sweep v1.0 , at a distance of 6 meters the uncertenty is about 2 cm. More accurate sensors are required to increase reliability. During the project e will try to minimize uncertenty trough high level reasonings (e.g. object segmentation and classification) inherited from computer vision field. Research activity
  24. 24. Knowledge improvement (Laura Genovese) Data collection and analysis of historical and archaeological information (also coming from documents, iconography, maps, photos, etc.) related to the underground heritage
  25. 25. Methods and Tools for Sustainable Enhancement Solutions to improve artificial caves cultural utilization and the integrated enhancement within a broader territorial scale. Project results dissemination.
