Abstract
SURVEY, HBIM AND CONSERVATION PLAN OF A MONUMENTAL BUILDING DAMAGED BY EARTHQUAKE
Highlights
1.1 Geometrical survey of monumental structures damaged by earthquakeSurveying a monumental building damaged by the earthquake means to analyse its geometries, the structural elements, the connection still existing between the different parts, in order to define its state of conservation, to make structural analysis and to plan a proper project of conservation, consolidation, seismic improvement or addition of new elements
How and by which instruments the geometric analysis are conducted depends on many factors, not always exclusively on the will of the experts involved in the restoration project, but more often dictated by political, technical, social or economic needs
The accurate geometrical survey is referred as fundamental operation even by national Directive for evaluation and earthquake risk reduction of cultural heritage (G.U. 29/01/2008 n. 24 and 2011 updates), which defines guidelines for preventive interventions on built heritage in order to make the structures less vulnerable in case of earthquake
Summary
Surveying a monumental building damaged by the earthquake means to analyse its geometries, the structural elements, the connection still existing between the different parts, in order to define its state of conservation, to make structural analysis and to plan a proper project of conservation, consolidation, seismic improvement or addition of new elements. The accurate geometrical survey is referred as fundamental operation even by national Directive for evaluation and earthquake risk reduction of cultural heritage 24 and 2011 updates), which defines guidelines for preventive interventions on built heritage in order to make the structures less vulnerable in case of earthquake. The wide use of tools and accurate surveying techniques makes it possible to achieve an adequate level of information related to the buildings, overcoming the difficulties due to accessibility of the damaged structures
