has a three-aisles structure built in two distinct construction phases. Originally it had vaults covering
the presbytery alone, while the aisles had an exposed wooden roof; between 1553 and 1559 the interior
of the church was renovated, creating the vaults to cover the three aisles, thus hiding the timber roof
from sight. The original roof was intended to be seen from inside the church and it is still well preserved
in the nave and southern aisle; it presented interesting construction features and some simple
polychrome decorations, still preserved in a few elements. On the basis of a careful dimensional,
geometric, material and constructional survey, the article will describe in detail the constructive
characteristics of the interesting fourteenth-century structure.

Remarkable historic timber roofs. Knowledge and conservation practice. PART 1 - Construction history and survey of historic timber roofs, 2022

where, thanks to the support of Bishop Speciano and some notable
families, it started the construction of the church of Saints Marcellino and
Pietro (1606-1620), the Schools and the College. The church model of the
aisleless rectangular hall – large enough to accommodate a large number
of faithful – forced the fathers to resort to unusual solutions for the area of
Cremona, which, over the centuries, also led to instability and structural
problems. The careful archival and bibliographic research made it possible
to investigate the wooden roof with wide-span “Palladian” trusses
(about 15.20 m), directing the diagnostic analyses, identifying the peculiarities
of the technical solutions adopted, in a continuous comparison between
indirect sources and in situ investigations. The construction events
of the trusses and secondary framing were investigated over a long period
of time, to include the succession of minute maintenance and repairs,
also carried out in the last two centuries; the complexity and stratification
of works carried out in phases and singular interventions, linked to the
chronological succession of events, is the basis for the interpretation of the
current state of the structure, therefore for a restoration intervention aimed
at protecting the building palimpsest.

The municipality commissioned the research to support the preliminary design of the preservation plan. The first digitisation level has been started from the richness of surveying data acquired from static and dynamic terrestrial laser scanning (TLS), and photogrammetry, overcoming challenging constraints due to the scaffolding covering the surfaces. The geometric survey allowed authors to acquire massively geometric and material information supporting the three-dimensional (3D) volume stratigraphic and the creation of the Heritage Building Information Modelling (HBIM). The paper proposes a shift from the Geographic Information System (GIS)-based analysis of the materials toward spatial HBIM management. Building Archaeology is turned into HBIM 3D volume stratigraphy, overcoming the bidimensional (2D) surface mapping, in fav...

The city administration, in co-operation with the conservation authority, started a programme in 2006 for the integrated restoration of more than 200 interiors in the Palace of Podestŕ and it gave the university the task of organising a project to acquire information on these buildings and help identify potential new uses. The paper presents a summary of the studies on the palace, surveys, diagnostic investigations and historical and archive research started more than a decade ago by the late Arturo Sandrini, designed to document and restore this complex which is a true and genuine repository of historical and archaeological information in the heart of the city. Behind the veil of the façades, recomposed after 1461 by Giovan Antonio d'Arezzo and repaired during restoration work in the last century, lies a dense stratification of continuous modifications, at times stately and at times humble, a background against which the still valuable mediaeval fragments stand out. The results include the identification of the many construction and distributive details, the fruit of difficult construction work over many centuries, and the characterisation of the conservation and restoration constraints which the final design will have to work with in a delicate balance between the requirements of conservation and those of public use.

Francesco, dei Filippini e di S. Orsola. Se, in tale contesto, pare complessa la definizione di una strategia di tutela a livello urbano, è invece riscontrabile, nelle decisioni riguardanti i singoli edifici, un modus operandi in parte ancora legato a teorie e prassi antecedenti il dibattito post-bellico

Vaulted systems, which are characterized by a variety of solutions developed across time and space, and whose knowledge is obtained during the analysis and diagnostic phases planned for preservation purposes, are mostly unknown to the public and collected information risks to be missed. This way, the chain of knowledge transfer is interrupted both for more informed future sustainable interventions and touristic purposes. The potentials offered by the adoption of a Pan European Virtual Hub to manage open data with semantic, spatial and temporal sub-setting allows to reconstruct a new framework of the construction techniques widespread across the world, permanencies and mutations to the common typologies with the contribution of skilled workers moving during the centuries across Europe. The case study of Palazzo Magio in Cremona with a rich abacus of vaults apparently belonging to a simple ‘cloister’ typology is described from the HBIM generation to data publication in the GeoDB HUB. Different Level of Detail, Geometry and Information, acquired in other Cremona Palaces, are feeding the DB and its vocabulary in a bottom-up process. The result is a contribution to the construction of an open access updatable inventory model inheriting the tradition of historical repertoires.

It is necessary to carry out progressively, but systematically, high-detailed surveys and to correlate them with the existing discontinuous documentation. Diachronic comparisons – referring to significant geographical areas in which evident constructive constants are recognizable – would highlight the variation over time of the models and their diffusion, while the comparison, especially synchronic, between solutions evidently different or apparently similar, would allow to better understand both the constructive choices and their static behaviour. A series of models – including the structural ones – should be elaborated, for directing design in a sector, often seriously flawed, prone to simplification and the introduction of high safety factors essenti...

The geometric continuity at the intrados makes generally possible the execution all over the span of frescoes, stucco and decorations. The construction of brick vaults, from the late Middle Age, was sped up by limiting the centering to the wooden planks arches that were instrumental in the profile determination. Nowadays, the availability of several procedures, phases and tools for carrying out a survey allows to draw reliable assumptions about the construction methods and the execution time. It is mandatory to determine the properties of the binders, the shape and dimensions of the bricks, and to carry out a comparison between the geometry of the intrados surface and the evidences emerging at the extrados. The support of the laser scanner technique allows to accurately identify the surface profile and thickness. All these indications...
