Several methods for creating building-related Linked Data graphs exist. This paper focuses on the conversion of IFC Building Information Models (BIM) to RDF Abox graphs using the emerging W3C Linked Building Data (LBD) modular ontologies: BOT (building topology), PRODUCT (classification of building elements) and PROPS (building-related properties)....

Combining conventional Building Information Modeling (BIM) tools and Linked Data technologies improves the options to connect building models to external datasets. Existing workflows in this regard expect a conventional BIM model - including object’s geometry - as a starting point. This paper presents a novel, alternative workflow oriented towards...

A reliable data exchange – often including geometry-related data – between stakeholders is crucial in construction projects. In this regard, data exchange frameworks built on Linked Data principles are very promising for combining disparate data sets. However, existing proposals to combine geometry and Linked Data either demand dedicated applicatio...

The Web currently hosts a vast amount of 2D images and 3D building models. Each repository has its own data structure and a limited set of semantics according to their own needs. With the advent of Semantic Web Technologies, the opportunity arises to combine these heterogeneous data sets and publish them as Linked Data. It is within the scope of th...

[link to the full text of the dissertation, available as open access: https://lirias.kuleuven.be/handle/123456789/674476] Collaborative built heritage projects require that a large variety of stakeholders, often using different tools and datasets, collaborate efficiently to conserve a valuable heritage building. Despite the opportunities of a thor...

Building Information Modelling (BIM) has changed the way in which buildings are conceived, planned and executed. Apart from their frequent use for as-planned buildings, BIM authoring tools have now been adopted for a number of years for digitising existing buildings as well, mostly by performing a ‘scan-to-BIM’ process: the creation of a BIM model,...

http://docs.ogc.org/wp/19-078r1/19-078r1.html The purpose of this document is to outline the benefits of representing geospatial data using semantic and graph technologies. It aims to provide motivation for OGC members to consider the publication of geospatial data using these technologies.

The exchange of construction-related data over the Web via Semantic Web Technologies is gaining interest in current research. However, most research focuses on non-geometric data, neglecting the description of geometry. While several methods to include geometry descriptions into a Semantic Web context exist, no uniform approach or general recommend...

The Damage Topology Ontology (DOT) is presented, a web ontology that provides terminology to represent construction-related damages and their topology as well as relations to affected construction elements and spatial zones. Besides the topology, classes and properties for documentation management and a minimal structural assessment have been propo...

In this paper the Damage Topology Ontology (DOT) is presented, a web ontology that provides terminology to represent construction- related damages and their topology as well as relations to affected con- struction elements and zones. Besides the topology, classes and proper- ties for documentation management and a minimal structural assessment have...

Currently, existing online 3D databases each have their own structure according to their own needs. Additionally, the majority of online content only has limited semantics. With the advent of Semantic Web technologies, the opportunity arises to semantically enrich the information in these databases and make it widely accessible and queryable. The g...

Linked Open Data (LOD) is the publicly available RDF data in the Web. Each LOD entity is identfied by a URI and accessible via HTTP. LOD encodes globalscale knowledge potentially available to any human as well as artificial intelligence that may want to benefit from it as background knowledge for supporting their tasks. LOD has emerged as the backb...

Any stakeholder operating in the AEC industry knows that designing a building is a complex and highly iterative task. The project evolves over time and changes happen rapidly, meaning that design requirements, as well as solutions (often as a consequence), must undergo revision. Since building requirements are, however, documented and handled in a...

The W3C Linked Building Data on the Web community group discusses different potential patterns to associate values to properties of building elements. In this paper, we are interested in enabling a different value association method for these and other properties, to account for changes in time, or to annotate a value association with metadata such...

During the design process of a shared ontology, domain experts, software developers and ontology engineers collaborate. As they typically have a different view on the ontology and understanding of the technology, it can be difficult to communicate proposals within the group. The proposed SPARQL-visualizer application discussed in this paper tackles...

Presentation

The use of Building Information Modeling (BIM) for existing buildings based on point clouds is increasing. Standardized geometric quality assessment of the BIMs is needed to make them more reliable and thus reusable for future users. First, available literature on the subject is studied. Next, an initial proposal for a standardized geometric qualit...

Point cloud segmentation is a crucial step in scene understanding and interpretation. The goal is to decompose the initial data into sets of workable clusters with similar properties. Additionally, it is a key aspect in the automated procedure from point cloud data to BIM. Current approaches typically only segment a single type of primitive such as...
