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: frost action
push out: crypto-florescence
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

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

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
