Monumentenwacht Vlaanderen MAKSin, a recording system for conservation assessments Risk- and value-based priorty ranking in historic interiors Monumentenwacht Vlaanderen vzw Veerle Meul, advisor historic interiors Inauguration Unesco Chair on Preventive Conservation, Maintenance and Monitoring of Monuments and Sites Raymond Lemaire International Center for Conservation, University of Louvain Louvain, Belgium, March 2009

Conservation assessments of the historic interior

Condition survey Currently  Visual survey, ‘quickscan’: material state and damage  Baseline (reference) report (benchmark)  Record of the extent and condition of an interior, damage

Preventive conservation assessment Identification and assessment of agents of deterioration 10 agents of deterioration (CCI-ICC, Waller and ICCROM):  Fire  Water  Wrong relative humidity  Wrong temperature  Physical forces  Light and radiation  Pests  Contaminants  Dissociation/neglect  Vandals and thieves

Problem The report Conservation assessment report:  Aim: document to support local conservation management planning  Recommendations with long list of activities  Advice for housekeeping and cyclic maintenance planning, mostly standard good-practice advices  List of strategies to avoid, to detect, to block, or to mitigate the effects of possible harmful agents  Long list of remedial conservation activities, only those to be done by specialists are ranked in order of urgency (ambiguous judgment by assessor)

Decision-making matrix with 4 parameters: RISK-based (principles ‘Cultural Heritage Risk Assessment’, as developed by ICCROM, CCI-ICC, CMN, ICN) A.Speed of continual decay processes; the frequency of incidents; probability of disasters B.Effect of consequential damage of defects (condition survey) OR of future damage by the agents of deterioration (risk assessment) C.Health and safety indicator VALUE-based D. Relative importance of the parts affected Priority ranking Decision-making matrix
