research presented here is the result of two related
theses, carried out in collaboration between PoliMi,
(Italy) and NTUA, (Greece). Part of it is carried
out within the INTERREG EU project framework, which
aims to the valuation and dissemination of the role
of the Church of S. Maria di Scaria (Vall' Intelvi)
in the international European exchange of skills in
the past centuries. It mainly focuses on the
Carloni's intervention (XVIII century), a local
family of craftsmen, famous across many European
cities and regions for the construction of monuments
with rich decorations. In this way they managed to
send holy gifts and money, but also offered their
skills in order to enrich the church of Scaria as a
symbol of their success. The laser scanning and
photogrammetric surveys have been carried out with
the on-site stratigraphic analysis and with the
quest for the scarcely available historical
documents, in an attempt to study the reconstruction
and the main transformations and chronological
phases, from the Romanic to the Baroque
interventions and to the more recent ones: An
integrated BIM approach has been chosen as an
experimental way of transmitting a piece of the
history of the church life to the local people and
also for touristic purposes. In order to disseminate
the information on the transformations of the
building and on the various decorations in a way
that would facilitate the readability and
interpretation of the monument by the visitors, a
little local museum, co-funded by the EU Interreg
programme, is planned to be realized mainly
containing the exhibition of the collections of the
sacred vessels and furnishings donated to the church
in the past. To enhance this aim a 3D object
modeling will also be exposed in the multimedia
section of the museum. A Heritage Building
Information Modeling (HBIM) has been developed,
while investigating the potential of an object
library specially generated to illustrate the
various structural elements, the multiple
construction technologies for the walls, the vault
system, the roof etc., and the decorative layers
(frescos, stuccos and frames), along with the
critical aspects faced by standard BIM in a complex
geometry shift from Surface approach to Object
modeling. The research contributes to the
explanation of the sequence and construction
technologies adopted for the vault system, the first
two vaults of the nave (their interesting texturing
and the particular geometry registered by laser
scanning related to the hypothesized centering),
with respect to the vault covering the altar and the
apse. The HBIM approach development is analyzed to
help the generation of a vocabulary and an abacus of
elements to be geographically referenced across
Europe to disseminate typical construction elements
and skills. PUBLICATION ABSTRACT
