The decisive feature of such components is that they reunite product properties from multiple product categories and therefore cannot be assigned to a specific category, such as static component or technical building equipment. Well-established product exchange standards within the construction industry such as ICF, simple ifcXML or VDI 3805 are not suitable to cover the wide-ranging properties of multi-functional components. In order to provide a comprehen-sive digital representation of such components and to enable the integration within the methodology of Building Information Modelling, the following paper presents a data schema based on Semantic Web Technologies. The designed multi-layered ontology enables and supports interpretability the wider use of Semantic Web technol-ogies in the construction industry.","PeriodicalId":193683,"journal":{"name":"eWork and eBusiness in Architecture, Engineering and Construction","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128950274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Multi-LOD model for describing uncertainty and checking requirements in different design stages","authors":"J. Abualdenien, A. Borrmann","doi":"10.1201/9780429506215-24","DOIUrl":"https://doi.org/10.1201/9780429506215-24","url":null,"abstract":"The design of a building is a collaborative process between multiple disciplines. Using Building Information Modeling (BIM), a model evolves throughout multiple refinement stages to satisfy various design and engineering requirements. Such refinement of geometric and semantic information is described as levels of development (LOD). So far, there is no method to explicitly define an LOD’s requirements nor any specification of its uncertainty. Furthermore, despite the insufficient information available in early design stages, a BIM model appears precise and certain. This can lead to false assumptions and model evaluations, for example, in the case of energy efficiency calculations or structural analysis. Hence, this paper presents a multi-LOD metamodel to explicitly describe an LOD’s requirements taking into consideration the information uncertainty. This makes it possible to check the consistency of the geometric, semantic, and topologic coherence across the different LODs. The model is implemented as a webserver and user-interface providing a means for managing and checking exchange requirements between disciplines. As part of this research group, we propose the development of a multi-LOD meta-model, which explicitly describes the LOD requirements of each individual building component type taking into consideration the possible uncertainties. The multi-LOD meta-model introduces two layers, data-model level and instance level, which offers high flexibility in defining per-project LOD requirements and facilitates formally checking their validity, such as defining and checking required information to support the Embodied Energy calculations at different design stages. This paper discusses the advantages in representing the uncertainties at early design stages and highlights the benefits of systematically managing and checking exchange requirements between disciplines. In order to ensure the model’s flexibility and applicability, its realization is based on the existing Industry Foundation Classes (IFC). IFC is an ISO standard, which is integrated into a variety of software products (Liebich et al. 2013). The paper is organized as follows: Section 2 discusses the background and related work of our research. Section 3 provides an overview of the multiLOD requirements and describes the design concepts, and Section 4 presents the meta-model design. In order to evaluate the multi-LOD model, Section 5 illustrates how it can be used to define and check the requirements of the Embodied Energy calculations, and a prototype implementation is discussed in Section 6 in terms of usability and possible integration in the design process. Finally, Section 7 summarizes our progress hitherto and presents an outlook for future work. 2 BACKGROUND & RELATED WORK 2.1 Level of Development (LOD) The concept of LOD is employed to manage the model evolvement through the different stages of the building life-cycle.

{"title":"Defining quality metrics for photogrammetric construction site monitoring","authors":"Felix Eickeler, A. Borrmann, Arnaud Mistre","doi":"10.1201/9780429506215-19","DOIUrl":"https://doi.org/10.1201/9780429506215-19","url":null,"abstract":"Point clouds are becoming a quasi-standard as a representation for capturing the existing context, for construction progress monitoring and quality control. While it is possible to create and track sites with a reasonable amount of effort using photogrammetry, different recording strategies and computational power lead to different properties of the point cloud. While the needed specifications are based on the concrete type of analysis and will vary from recording to recording, the overall properties of the reconstruction toolchain are immanent to assess the performance of further processing. Within this paper we will present different criteria for the quality and evaluation of point clouds in respect to construction sites. These indicators together form a benchmark and can be used to evaluate a given toolchain and estimate the properties of a resulting point cloud. While all these publications tend to apply slightly different use cases, the first hurdle for a successful identification is registration of the captured point cloud to the geometric representation. For the relative registration of the geometric model, two base approaches exist in literature: feature-based recognition and the reduction of distances between the alignments (optimization). An Iterative Closes Point (ICP) (Besl and McKay, 1992) showed good results (Bosché, 2010; Masuda et al., 1996) after a successful manual initial alignment. It also worked well in combinational approaches (Huang and You, 2013). A generalized approach for surface to pointcloud was deducted by Segal (Holz et al., 2015; Segal et al., 2009). All these approaches need initial alignment or filtering since the ICP is a non-convex method. This problem leads to a global alignment when dealing with noisy construction site captures (Braun et al., 2016; Tuttas et al., 2017). The SfM/MVS based approach was identified as less accurate but much cheaper (Golparvar-Fard et al., 2011) compared to laser scanning and lead to a discussion of quality (Toth et al., 2013). To predict the quality of site captures, recent developments showed two different approaches: deducing the quality of the recording based on the result of the identification process (Rebolj et al., 2017) or using pure point cloud related properties and toolchains (Angel Alfredo Martell, 2017; Dyer, 2001; Haala et al., 2013). Following up on these publications, we present simple metrics of quality and emphasize on developing robust independent criteria. 3 PROCESS OF RECONSTRUCTION 3.1 Structure from Motion The structure from motion pipeline provides us with the first step to create a 3D model from taken images. It eliminates the need of a calibrated camera where the extrinsic and intrinsic parameters are fixed and known. In all taken images, points of interest are calculated and their correspondence is determined. Rejecting flawed correspondences, each camera is registered relative to the initial match.

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 predominantly manual manner, the work processes are not aligned with the dynamic nature of the projects. Tracking and acting upon changes is a manual, and therefore an errorprone and labour intensive task. In this article, we suggest a generic method for working with the concept of spaces at different abstraction levels in order to compare requirements with actual properties in a non-static manner using semantic web technologies, primarily developed by the W3C Linked Building Data (LBD) Community Group. The generic modelling approach has the potential of also being applied to other concepts than building spaces. an RDF-graph (Resource Description Framework) following the suggested modelling approach, and partly by using a custom developed exporter for the BIM authoring tool, Revit.
