INTEGRATED 3D SURVEY AND DIAGNOSTIC ANALYSIS FOR THE BUILDING ENGINEERING: THE FORMER KINDERGARTEN SAN FILIPPO NERI IN DALMINE

Abstract. The paper aims to emphasise the positive contribution that the 3D laser scanning and digital photogrammetry survey, integrated with diagnostic analysis techniques, can make in the field of construction engineering. The case study of the former kindergarten San Filippo Neri in Dalmine intends to contribute to the development of methodologies and operational tools related to the knowledge and conservation of modern and contemporary heritage. After archival research aimed at retracing the building's technical-constructive evolution, the study was extended out through the metric and morphological survey of both its external walls and internal spaces, paying special attention to the analysis of the deformations of the large horizontal surfaces, such as floors and ceilings. Diagnostic investigations – thermographic and microclimatic – have completed the survey campaign, so allowed to read both the envelope and the substance of the building, and to identify the critical issues. This work adopts and shows the correct glide slope to succeed in an adaptive reuse project in which the design stage can result solely from the in-depth study of the building.
