MDDS: monument damage diagnostic
system.
A decision support system for architects,
conservators, authorities, students, ……
Degradation processes
• degradation processes: mechanism & essential
conditions
• influencing factors, like
• environment (conditions)
• material properties (conditions)
• Diagnosis + conservation / intervention
• Use MDDS
2
Why a diagnosis?
• Diagnosis of damage: assessing why restoration /
intervention / maintenance is necessary
• Extremely important in order to guarantee a
durable conservation
3
Look-alike damages: push out
push out: cryptoflorescence
4
push out:
frost action
Comparable crack types: different causes
5
Illustrated glossary of
damage types & definitions
is contained in MDDS
6
Foreseen users
• Restoration architects
• Authorities / Monumenten Wacht
• Education (university students)
• General
• Support communication: damage atlas, definitions
• Background information: diagnosis, conservation
techniques
7
Practical way of operating
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

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
