Integrating Bim and Gis Data to Support the Management of Large Building Stocks

Abstract

<p><strong>Abstract.</strong> The survey phase is an essential prerequisite for effective management and improvement of existing buildings. The low accessibility of information regarding the design and construction phases and the current state of the buildings, are the main causes of inefficient actions on existing buildings. The lack of “As Built” documentation (building components, installations, etc.) and the complex task of detecting their current status in terms of use (intended use and space dimensions, environmental context, etc.) and maintenance (conservation status of building components, age of the technological installations, previous maintenance work, compliance with current regulations, etc.) causes deep difficulties in planning, scheduling and controlling appropriate interventions. Starting from these assumptions, this paper shows the findings of a research, aimed at testing the integrated use of Building Information Modeling (BIM) and 3D Geographic Information Systems (3D GIS) in order to structure knowledge. The research concerns a case study and it has actually led to the development of a BIM- 3D GIS workflow which formalizes knowledge and information involved of a significant building, according to its management: the INA houses by Enrico Mandolesi, a residential complex for about 2500 inhabitants built around 1960 in the eastern suburbs of Cagliari (Italy).</p>

Building Information Modeling and Geographic Information System: Integrated Framework in Support of Facility Management (FM)

“…Vach et al [51] present an integrated GIS-BIM-FM system for the management of public real estate in the city of Prague, Czech Republic. Vacca et al [52] show the results of research about the integration between BIM and 3D GIS, applied to a housing project in the city of Cagliari, Italy. Mangia et al [53] provide a comprehensive study, based on the analysis of the literature, concerning BIM-GIS integrated systems for managing large building stocks.…”

Management of the maintenance process in social housing: A case study

“…Compared to the work by (Vacca et al, 2018), the DMS of this study focuses on the need for an agile tool for all the stakeholders involved, thus the choice of developing it as a web application. For the needs of this case study, the model is linked in the viewer with its footprint on GIS maps by means of the ID IBU, which did not require a model conversion.…”

“…Thus, the data collection is a fragmented process that leads to lacking knowledge and poor control over the assets (Pinti et al, 2018). In this regard, Vacca et al (2018) presented a work involving a BIM/GIS integration for large building stocks in social housing. The result is a stock of 3D building models in a GIS environment which allows querying building components (features not available in BIM software such as Revit), supporting the maintenance and management phases of the building's life cycle.…”

Highway Alignment Optimization: An Integrated BIM and GIS Approach

“…BIM uses a detailed parametric model that simulates the project throughout its life cycle to effectively manage building projects [23]. The BIM model provides the benefits of rich geometric and semantic information throughout the project life cycle [24]. GIS is a powerful tool for performing complex spatial analysis and in generating the optimum path, including data management, spatial analysis, and geographical visualization [25].…”
