For this purpose, the Systematic Literature Review approach (SLR) was employed. The review which was based on studying 48 sources identified six categories to classify the motives and barriers for the two C3DP techniques; cost, transportation, design flexibility, workers and materials, production process, and environmental considerations. The literature identified the cost as the main factor that influences the choice between the two techniques. The presented list of motives and barriers is helpful to support decision-making in C3DP projects.

Aiming to increase the knowledge about DT, this study analyzes how DT can be understood in the BE sector and investigates its different potential benefits and expected challenges. To do so, the Systematic Literature Review (SLR) approach was employed. Using 228 publications, the current study presents a proposed definition and structure for DT systems. The proposed structure is based on four main layers: physical, digital, application, and user layers. The study also classified the applications of DT into six groups: sustainability and environmental, facility management, safety, health, and risk management, structural performance, construction management, and architectural and urban-related applications. The challenges of DT implementation were also grouped based on industry-related, social and organizational, economic, technological, and political and legal challenges. Based on the results, future research directions and practical recommendations were presented to support the successful deployment of the technology.

We first (Chapter 2) introduce the detailed testing strategy of REACH, which details and brings forward previously described conceptual provisions (see Deliverables D4, D9 and D29) and responds to previous reviewer comments (R5 and R6, second review, November 2017; aiming at the improved emphasis of geriatric and medical aspects and their normalisation across Touchpoints and project activities). In response to the reviewers’ comments, REACH re-aligned some of its resources and formed a medical/geriatric task force (SK, HUG, DTU, TUM), which analyses and streamlines testing activities across Touchpoints, clarifies the common goals and measures, and works towards a normalisation of study designs and tools used across the project. We outline in this context the overall hypothesis for the REACH system along with four well-defined sub-hypotheses for each Touchpoint. Based on this, in Chapter 3, we present our methodological approach with regard to testing in REACH and provide an overview and a classification system for all testing activities carried out. Accordingly, in Chapter 4, we present the results (documentation of the carried-out testing activities), and in Chapter 5, we interpret the testing results. Chapter 6 summarises the state of play regarding testing in REACH and outlines the next steps and upcoming activities. The Appendix contains the full trial reports sorted according to a variety of items. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 690425.

Abstract: This deliverable report examines the outcomes of the REACH research project with regard to data privacy and data security, associated with Task T7.5. This document gives an overview of our analyses involving ethics and privacy concerns in terms of the individual touchpoints and shows how these findings guided the project towards the determination of the medical purpose and intended use-cornerstones to on the path to market entry. In addition, we provide a brief overview of how the guidelines regarding data protection and encryption influenced the technical design and implementation of project components. Furthermore, we provide an update on the management of legal implications (and the implications resulting from this for system requirements and business strategy) of the use of machine learning and artificial intelligence in the context of REACH solutions, incorporating an external expert opinion. Finally, this deliverable report contains a summary of our approach towards risk gov-ernance and standardization in this regard: our work in REACH on privacy and security schemata, culminated in a CEN Workshop Agreement (guideline) that generalizes REACH outcomes and makes them accessible and usable beyond the REACH consortium .

It is anticipated that mechatronic and automation technologies would play an important role in transforming the construction industry to embrace for the fourth industrial revolution. However, construction automation problems bring up new research challenges that diverge from traditional methods. Unlike the factory environment, which is typically structured and predictable, construction sites are dynamic places where the working environment is unstructured and always changing. Due to lack of skilled labor, time and cost overruns, quality deficiencies, and the recent pandemics, mechatronic and automation technologies offer solutions for future safe, rapid, performative, prize worthy, and digitally protocolled construction projects. The coexistence of human workers, heavy vehicles, varying environmental conditions, and automated mechatronic systems also make safe human–machine interaction an important issue. Beyond expertise in a specific discipline, construction automation also requires multidisciplinary expertise to integrate with various fields, such as Internet of Things (IOT), robotics and its construction oriented subsystems, adaptive/robust control, machine vision, sensing technologies, artificial intelligence (AI), and building/construction/process information modeling (BIM/CIM/PIM) for automated construction process management and design. The main aims of this focused section in the IEEE/ASME Transactions on Mechatronics (TMECH) are to document the current state of the art in mechatronics and automation for constructions, and to present new results in several emerging research areas.

Building inspection and maintenance are crucial for ensuring structural integrity and safety. However, traditional manual methods are time-consuming and pose safety risks, especially for exterior inspection at height. Robotics offer a promising alternative to enhance building inspection efficiency and cost- effectiveness, but still in the early development stage. This paper aims to review and analyze the state-of-the-art design and development of robotics for building exterior inspection, referring to the literature published in the last two decades. Firstly, the review classifies different types of robots for building exterior inspection in terms of locomotion and adhesion modes, and discusses the capability of robots from navigation, obstacle surmounting, wall-to-wall/floor transition, curved wall climbing, grasping, barrier avoidance, and self-protection. Secondly, the paper examines the applicability of robots to various building materials for inspections and summarizes the most typical applications (i.e. glass curtain walls, tile walls, and concrete walls). Thirdly, the paper discusses the typical data collection and analysis methods for building exterior inspection using robots. The paper also explored potential enhancements for robotic inspection through the integration of building information modeling, augmented reality/virtual reality, and the involvement of human-in-the-loop. Finally, the paper summarizes the typical application of robotics in building exterior inspection regarding robot types, inspection applications, data collection and analysis methods, discusses the challenges, and outlines the future directions.

Das in vielen Fachbereichen ausbaufähige Angebot von Digitalthemen in der Hoch- schullehre wird hiermit dauerhaft erweitert. Ein Digitalisierungskolleg besteht aus einer Vorlesungs- reihe mit angrenzendem Seminar, in denen Studierende interdisziplinäre Lösungen für Fragen der digitalen Transformation entwickeln. Geleitet werden sie von etablierten Wissenschaftlerinnen und Wissenschaftlern, aktiv betreut und ausgestaltet von ein bis zwei Coaches. Kernelement sowohl des Kollegs als auch der einzelnen Projekte ist die Interdisziplinarität. Eine*r der beteiligten Projekt- leiter*innen hat einen direkten Bezug zur Technik und kommt aus der Informatik, der Wirtschafts- informatik, der Elektrotechnik oder vergleichbaren Disziplinen. Zielgruppe der Projekte sind Studierende verschiedener Disziplinen im Masterstudium oder in den letzten Semestern eines Bachelorstudiums. Durch die Teilnahme erwerben auch Studierende aus digitalisierungsfernen Fächern frühzeitig umfangreiche IT-Kenntnisse. Als Begleiteffekt der umfangreichen Vernetzung zwischen den Digitalisierungskollegs (Studierende, Coaches und Projektleitende) entsteht bereits zu Beginn einer wissenschaftlichen Karriere eine große digitale Community. Alle Teilnehmenden lernen frühzeitig die interdisziplinäre Zusammenarbeit und verbessern erheblich ihre Karriere- chancen innerhalb und außerhalb der Wissenschaft.

From large scale applications in the context of city planning to the detailed evaluation of critical infrastructure they enable specialists to observe problems, interpret relationships, test solutions virtually and apply them in the real world. This is only feasible if the individual underlying digital model meets the requirements imposed by the analysis at hand. In practice, especially models of existing buildings are not easy to come by as the information describing the existing structure is often scattered across multiple different data sources in various formats. Previous research efforts have outlined methodologies which leverage machine learning, computer vision and subsequent semantic enrichment in order to achieve the (re)construction of such building models. However, these methods are generally not integrated with each other, nor do they consider being able to interface with a shared repository of building related data. In this paper we present a methodology which focuses on establishing a common context for all building related data by utilizing the Industry Foundation Classes (IFC) schema. In particular we focus on utilizing readily available geometric and semantic data originating from geographic information systems as a basis, subsequently referencing additional data sources in their corresponding context and finally outlining interfaces with downstream enrichment processes in both directions. Through incorporating contextualized (IFC) data into the early stages of the remodeling workflow, we outline an end-to-end process from the initial component-based data-acquisition to the as-built building information model. In establishing a standardized foundation for data exchange and collaboration it enables all stakeholders to work more seamlessly across different stages of the remodeling project.
