Zusammenfassung:

Work flows for digital construction employ a multitude of software types. Among others, authoring-, simulation- and validation- tools or collaborative platforms can be cited. Information exchange is supported by Industry Foundation Classes (IFC), a vendor independent data scheme, developed and managed by buildingSMART international and standardized by ISO. IFC can be considered as the “backbone” for a lossless digital communication of product data in construction. It is therefore important to understand which information can be transferred by IFC and how this complex data scheme is structured. The present book first introduces the IFC structure using buildings as examples, paying a particular attention to placement and spatial organization of constructed objects. The concept is then extended to the newest IFC version 4.3, treating infrastructure assets like roads and bridges. Complementary chapters explain how geometry is represented by IFC, the interaction of BIM and GIS systems, as well as the future of IFC. Finally, buildingSMART standards are presented and contextualized for their use in digital workflows. This book is recommended for everybody who is interested in construction and maintenance processes driven by openBIM methods, in particular for AEC professionals defining data exchange requirements as well as BIM Coordinators and Managers.

Digital modelling of underground volumes, including the visualization of confidence levels for the positioning of subsurface objects

Wissenschaftlicher Artikel ArODES

Kamel Adouane, Fabian Boujon, Bernd Domer

Applied Sciences, 2021, vol. 11, no. 8, article no. 3483

Zusammenfassung:

This paper addresses the issue of offering a consistent 3D visual rendering of subsurface objects when databases face non-completion. Digital modelling of subsurface objects, like utility lines, underground buildings or tree roots, is a difficult task. Data available are incomplete and not precise. The in situ acquisition of existing objects to increase data quality is complex and, therefore, costly. In this paper, a methodology to obtain missing spatial and geometrical data through field or empirical means is proposed. In addition, confidence levels are assigned to existing and derived spatial and geometrical attributes. They are consolidated on a class level and visualized through a bounding shape, called secondary object.

Du BIM pour le sous-sol?

Professioneller Artikel ArODES

Cadastre revue spécialisée consacrée au cadastre suisse, 2019, no. 31, pp. 26-28

Zusammenfassung:

La modélisation numérique de l’environnement urbain est au cœur de l’attention depuis quelque temps, du fait notamment de la propagation de la méthode BIM. Le BIM, technologie disruptive1, bouleverse notre façon de travailler à toutes les échelles: si les systèmes d’information géographique (SIG) gèrent aujourd’hui des territoires étendus, les systèmes de BIM aident d’ores et déjà à planifier les ouvrages au millimètre près. La Haute école du paysage, d’ingénierie et d’architecture de Genève (HEPIA) a été mandatée par l’Office fédéral de topographie swisstopo et le canton de Genève pour répondre à la question suivante: jusqu’à quel point ces deux technologies peuvent-elles être utilisées pour une modélisation structurée des objets situés en sous-sol?

A model-based approach to convert a building BIM-IFC data set model into CityGML

Wissenschaftlicher Artikel ArODES

Kamel Adouane, Rudi Stouffs, Patrick Janssen, Bernd Domer

Journal of Spatial Science, 2019

Zusammenfassung:

Digital building modelling faces issues related to inconsistent integration/interoperability, in particular for a BIM GIS convergence. A consistent data conversion approach should consider semantic and spatial geometric modelling, therefore potentially leading to a loss of spatial geometric information. This paper simplifies semantic solving, and concentrates on the accuracy of the spatial geometric representation to avoid conflicting 3D spatial mismatches. To solve the geometry, original spatial specifications in 3D described in the IFC data schema are considered for all objects present in the model. The method is explored with a main BIM-IFC model, and additionally tested with two other models.

Buch ArODES

un vademecum d'économie, de droit et de planification pour le bâtiment

2017, Presses polytechniques et universitaires romandes (PPUR) : Lausanne, 525 p.

Yohann Schatz, Bernd Domer

Zusammenfassung:

La formation des architectes et des ingénieurs met principalement l'accent sur les aspects qualitatifs du métier, parfois au détriment des connaissances en lien avec la gestion du projet de construction. La maîtrise du budget, l'organisation des appels d'offres, la gestion des délais ou les questions de droit font néanmoins partie intégrante des nombreuses prestations que se doit d'assurer tout constructeur vis-à-vis de son client. C'est afin de combler cette lacune que ce vade-mecum, rédigé par des enseignants de la Haute école du paysage, d'ingénierie et d'architecture de Genève (hepia), a été conçu. Synthétique et pratique, il procure l'ensemble des clés de compréhension indispensables à la conduite d'un projet de construction, en s'attachant aux questions de droit public et de droit privé, d'organisation, de planning, de budget, de gestion du chantier ou de cycle de vie. Rédigé dans un langage clair et accessible à tous, précis et exhaustif, sa lecture peut se faire de manière linéaire ou séquentielle, selon les besoins du lecteur. Une référence tout spécialement conçue pour les praticiens, les étudiants en architecture et ingénierie dans le domaine du bâtiment, ainsi qu'à tous ceux qui se lancent dans un projet en tant que maître d'ouvrage.

Optimizing IFC-structured data graph for code compliance checking

Konferenz ArODES

Proceedings of the 29th EG-ICE International workshop on intelligent computing in engineering, 6-8 July 2022, Aarhus, Denmark

Zusammenfassung:

Construction code compliance checking requires applying specific computer-interpretable rules on datasets. A proposed solution is to represent IFC data as an RDF graph and perform rule-checking using a rule engine. However, the generated graph has a complicated structure since it follows the IFC data model. Consequently, the definition of compliance rules can be challenging, and rules are sensitive to variations of input graphs structure. A methodology is proposed to optimize graphs by giving them a predefined or "standardized" structure. A case study shows that optimization allows the formulation of more straightforward and easier-to-write compliance rules, applicable to all standardized graphs regardless of the initially used BIM authoring tool. In addition, graph size is significantly reduced.

Qualifying spatial information for underground volumes

Konferenz ArODES

Kamel Adouane, Fabian Boujon, Bernd Domer

Proceedings of eg-ice2021, 30 June- 2 July 2021, Berlin, Germany

Zusammenfassung:

Urbanization and condensation of habitants per m2 have led to an intense use of subsurface volumes as construction space. Planning and constructing in such spaces is a very challenging task, since knowledge of existing objects is fragmentary and imprecise. An intelligent identification of present objects and thereby detecting available volumes would increase the design quality of projects, since incidents reported during field excavations (Tanoli et al., 2019) are numerous and costly. Combining existing official territorial data with intelligent methods for information completion, compliance checking and data management, is a promising approach as it has been partially demonstrated by the use of ontologies (Caselli et al., 2020; Métral et al., 2020). The minimum level of necessary information for a model-checking framework is identified and formalized by an ontology. The ontology then serves as a basis schema for a triple store database, storing data, completion and compliance rules. The process of data completion allows to qualify the confidence in spatial information delivered.

a case study

Damien Varesano, Eric Amos, Bernd Domer, Francine Laferrière, Dario Redaelli, Marco Viviani

Proceedings of 20. Status-Seminar "Forschen für den Bau im Kontext von Energie und Umwelt", Zurich, Switzerland, 6-7 September 2018

Zusammenfassung:

In order to reduce environmental and financial costs caused by construction material flow, web platforms have been created. Their objective is to increase the visibility of materials available on construction sites and promote their reuse. A benchmark of existing national and international platforms - considering functional aspects, effectiveness and how the platform interacts with local construction community - has been established by the research team. Strengths and weaknesses of each analyzed platform have been identified, giving an up-todate picture. The benchmark points out, that no “comprehensive“ platform, providing material exchange services as well as support for a large and strong user community, exists. Such a platform could be enhanced by several features – like linking it to geographical information systems and technical assistance, creating a coordinated waste management among construction sites thereby. The Great Geneva Area has been identified as an ideal location to implement the concept and an action plan has been proposed.

Le vivant et le recyclage des matériaux de chantier, facteurs de résilience environnementale et de lien social

Zusammenfassung:

L’impact sur le plan social, écologique et économique de la construction d’habitats, de bâtiments administratifs et industriels, d’infrastructures de transport et de loisir et leurs aménagements, n’est plus à démontrer. Épuisement des ressources naturelles, transformation des matériaux, transports, gestion des déchets de chantier et d’excavations, autant de sources d’émissions de GES et d’effets négatifs sur le sol et le paysage qui influent sur la qualité de vie et les perspectives d’avenir de la population, à l’échelle du territoire, de la ville, du quartier. Cette présentation aborde la question de la prise en compte du vivant dans une démarche d’optimisation de la qualité de notre environnement, dimension encore trop souvent sous-estimée dans le processus de la construction et véritable enjeu de ce début de 21e siècle. 1. L’impact écologique : tenir compte du sol, non comme un matériau inerte, socle physique aux seules qualités de support, mais comme un complexe vivant de grande valeur et grande fragilité, rare et indispensable à la végétation et à la gestion des eaux. Le sol fertile se raréfie en milieu bâti, dans la ville en particulier où l’anthroposol et les revêtements imperméables deviennent la règle. 2. L’impact social : Mettre en relation les acteurs du site, une responsabilité sociale. La prise en compte des personnes, habitants actuels et futurs, voisins, la population dans son ensemble et les visiteurs, tous impactés de près ou de loin par les nuisances des travaux, la transformation des lieux, la perte d’éléments repères et à la recherche affirmée et croissante d’une qualité de vie en espace construit.

a round trip between GIS and IFC

Sébastien Chognard, Alain Dubois, Yacine Benmansour, Elie Torri, Bernd Domer

Advanced Computing Strategies for Engineering. EG-ICE 2018

Zusammenfassung:

Building design and surrounding environment are influencing each other. Environment is usually described by a Geographic Information System (GIS), while buildings are often designed with Building Information Modeling (BIM) software. Despite some differences on technology and standards, GIS and BIM deal with geometrical data and attributes. Possible links between GIS and BIM using the City Geographic Markup Language (CityGML) and the Industry Foundation Classes (IFC) as standard exchange formats have been studied [1, 2, 3, 4]. The present work establishes an exchange between IFC and GIS features. As an open format, IFC files can be handled by AEC-related software. It is therefore of interest, if IFC can be used for a roundtrip between GIS and BIM. A three-step translation protocol has been developed and tested: (1) Data from GIS had to be transformed into an IFC reference environment model. (2) A test building has been designed. Imported environmental elements have been edited as well. (3) The exported IFC file was then imported into GIS data sets in order to update existing data. The process employed the FME software to convert GIS to IFC and back. Data management tasks have been delegated to a database complying with the IFC format (BIMserver). The accurate import and export of data has been monitored over the entire data exchange process. This study uses the development of a digital construction permit submission procedure for the canton of Geneva in Switzerland.
