Presentation Transcript

  1. MDDS: monument damage diagnostic system.A decision support system for architects, conservators, authorities, students, ……

  2. Degradation processes • degradation processes: mechanism & essential conditions • influencing factors, like • environment (conditions) • material properties (conditions) • Diagnosis + conservation / intervention • Use MDDS

  3. Why a diagnosis? • Diagnosis of damage: assessing why restoration / intervention / maintenance is necessary • Extremely important in order to guarantee a durable conservation

  4. Look-alike damages: push out push out: crypto-florescence push out: frost action

  5. Comparable crack types: different causes

  6. Illustrated glossary of damage types & definitions is contained in MDDS

  7. Foreseen users • Restoration architects • Authorities / Monumenten Wacht • Education (university students) • General • Support communication: damage atlas, definitions • Background information: diagnosis, conservation techniques

  8. Data are introduced on: • - the building • - the wall or other element under investigation • - the materials composing the wall • - the damage found for wall or building element + per material • - the area (or location) on the wall where the damage is present • The system subdivides the data in: • - properties • descriptions • Inspector is supported in making hypotheses, reaching a diagnosis and planning interventions Practical way of operating

  9. MDDS seminar Lisbon (2005) MDDS workshop Zeist (2005)

  10. MDDS: students work on site (2005 / 2006)

  11. MDDS: workshop Leuven (Feb 2007)

  12. Systematic description of wall Damage to wall Damage to individual materials

  13. Sampling for measurement moisture and salt content

  14. Visual representation salts

  15. Information from EU projects: COMPASS

  16. Information from EU projects: Saltcontrol

  17. Report

  18. MDDS - Monument Damage Diagnostic System (current state) • Prototype system • Assessment of state of conservation historic buildings • Support diagnosis • Support interventions / treatments / measures • Documentation of monuments (archive) • Interactive • User is supported during investigations • User finally decides on interventions
