Abstract

This paper discusses the creation of an integrated historic BIM-GIS for the complex of San Pietro al Monte, an important Romanesque monument in Civate (Italy) inscribed in the UNESCO tentative list with other seven medieval Benedictine settlements. The reason behind the choice of an integrated H-BIM-GIS solution is motivated by the large extension of the considered area (about 30 km2) and the need for multi-scale digital information integrated into a 3D parametric environment. The model includes geospatial information at a territorial scale and in situ digital data capturing the complex at a higher level of detail. The work aims at exploring the pros and cons of a novel parametric 3D environment able to integrate both BIM and GIS data, methods, and processing tools in the case of historic buildings and sites.

Summary

Introduction

In recent years, Building Information Modeling (BIM) has gained progressive importance for heritage documentation. HBIM (Historic BIM) was described by [1,2] considering the case of historic buildings, notwithstanding that parametric modeling from laser scans had already been proposed by the same authors in [3]. Different authors have proposed different procedures and methods to generate accurate HBIM for different typologies of historic constructions, such as churches and cathedrals, villas and palaces, castles, and bridges, among others [4,5,6,7,8,9] Digital recording methods such as laser scanning and photogrammetry [10] are often used to capture accurate and dense point clouds that can guide the modeling phase in BIM software.
