D28 is an update on D27. Additional associated deliverables are D12, D13, D23, D31, and D44. Abstract: In order to provide a comprehensive summary of all testing activities, the medical core group (DTU, HUG, SK, TUM) created a mini protocol template (which requested the outline of some methodological aspects of each study such as study designs, the recruitment phase, population under investigation, etc.), and ensured that data were submitted and provided by the trial manager to the core group. In this deliverable we present, structure, and interpret the formalized results of the final testing and optimization activities of all testing activities in REACH. The deliverable includes the summarization of testing and evaluation of final testing of a continuously improved system in the form of prototypes in real world environments and the presentation of optimization measures. The deliverable is an update on deliverable D27 and associated with tasks T6.5, T6.6, T6.7, T6.8. In reaction to the reviewers' comments we initiated additional trials focusing on practice cases. Those trials are specifically ladled and included in the updated overview. A review on factors, i.e., falling, frailty, cognitive decline , sarcopenia, social isolation, and malnutrician, was performed to show the most important cofactors. Addressed in this deliverable is also the role of privacy and the hierarchy of needs which are essential components of the acceptance and use of technology .

Worldwide labour and resource shortages, the need to increase circularity and resource efficiency, new materials and the increasing utilisation of digital construction tools in the planning and construction industry massively spur the uptake of robotic solutions for on-site construction. The initial boom of construction robots happened in the 1970s, driven by the Japanese construction industry. In the 1980s, a combination with parallel developments was supposed to achieve complete, integrated robotic on-site factories. From the mid-1980s onwards, the global interest in construction robots decreased gradually. Bulky and expensive systems, complex on-site navigation and logistics approaches, a narrow scope of tasks, inflexibility, incompatibility with on-site work organisation and professional qualification, low usability and insufficient inter-robot coordination capabilities revealed the immaturity of the systems. Only a few organisations predominantly situated in Asia such as Takenaka, Obayashi, Kajima Corporation, Nihon Bisho Co., Samsung, and Hitachi maintained development activities. However, since the mid-2010s, development activities are gaining traction again. On the application side, this is mainly driven by trends such as the need to upgrade the energy performance of buildings in Europe, a global necessity to remove asbestos from existing structures, and a demand for enormous quantities of high-rise buildings all over East Asia. On the system side, the renewed interest stems from major advances in physical–mechanical robot technology in other automation-driven industries such as the automotive industry. Robots became lighter, more flexible, their parts modular and interchangeable, more user friendly as well as significantly cheaper. On the digital side, the BIM-to-Robot pipeline was subject of intensive reserach and development. More and more methods and tools help to increase the usability of robots and facilitate the simulation and optimisation of robot-driven construction processes. In the last 4–5 years, the worldwide growing need and interest in construction robotics became highly evident. More than 200 robot systems are pushed by start-ups and spin-offs and their investors to the market. This is backed by an enormous number of activities and projects carried out in the academic area pushing to the boundaries of what is technologically possible. Major associations and their conferences increase significantly in popularity such as ISARC (International Association for Automation and Robotics in Construction), EC3 (European Council of Computing in Construction), and Robots in Architecture. Competency in digital construction, automation and robotics becomes a key for all stakeholders in the construction industry and many universities worldwide launch dedicated interdisciplinary programs. Powerful governments (China) and major funding programs such as Horizon Europe (Europe) massively request and fund the development of robotic solutions for construction such as drones, mobile robots, 3D-printing solutions, cable-driven robots, and exoskeletons. Regulators and standardisation organisation start to develop the first certification and standardisation schemes for construction robots and large software companies make attempts to allow to simulate and program robotic construction processes efficiently and robustly based on digital building and construction data. To showcase the diversity of cutting-edge research in the area, this special issue invited eight extended versions of selected papers from the ISARC 2021 conference. As such, this issue covers digital approaches to embed fabrication and robot information in BIM and IFC and program robots directly from digital building models. New robot systems spur novel robotic production processes, and machine learning enable novel logistics approaches for building components that may ultimately lead to robotic cranes and other robotic on-site logistics and handling solutions (including autonomous construction machines). In parallel, systematic evaluation and robot development methods are developed that allow to shed light on their performance in the construction process.

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 presented Deliverable (associated with Task T6.2) provides a presentation/demonstration of the executed trials including different partner groups in different use case settings. It is worth mentioning that since this deliverable report has a nature of “Demonstrator”, this document tries to show the implemented trials. Therefore, it was tried to integrate as many pictures as possible to prove the trials. This deliverable report targets mainly the Touchpoints TP1, TP2 and TP3. This is decided due to the person months of the partners involved in this task. In these trials the partners addressed a pre-integration of sub modules involved in the future REACH presentation. Additionally, this deliverable discusses the trials from the first step which is the planning and execution, then to the execution/implementation and then to analysis and studying the results. Furthermore, using these trials the deficiencies and shortcomings were identified in these lab experimentations. Early detection of shortcomings and deficiencies will lead to simplified implementation and adjustment before reaching the final testing and integration stages. At the current time, the partners are already planning and preparing for the future tests/trials at the use case settings sites.

T1 - COVID-19 and the ageing workforce: global perspectives on needs and solutions across 15 countries JF - International Journal for Equity in Health volume N2 - BACKGROUND: COVID-19 has a direct impact on the employment of older people. This adds to the challenge of ageism. The World Health Organization has started a worldwide campaign to combat ageism and has called for more research and evidence-based strategies that have the potential to be scaled up. This study specifically aims to identify solutions to combat the adverse effects of COVID-19 on the global ageing workforce. METHODS: We present 15 case studies from different countries and report on what those countries are doing or not doing to address the impact of COVID-19 on ageing workers. RESULTS: We provide examples of how COVID-19 influences older people's ability to work and stay healthy, and offer case studies of what governments, organizations or individuals can do to help ensure older people can obtain, maintain and, potentially, expand their current work. Case studies come from Australia, Austria, Canada, China, Germany, Israel, Japan, Nigeria, Romania, Singapore, Sweden, South Korea, Thailand, United Kingdom (UK), and the United States (US). Across the countries, the impact of COVID-19 on older workers is shown as widening inequalities. A particular challenge has arisen because of a large proportion of older people, often with limited education and working in the informal sector within rural areas, e.g. in Nigeria, Thailand and China. Remedies to the particular disadvantage experienced by older workers in the context of COVID are presented. These range from funding support to encouraging business continuity, innovative product and service developments, community action, new business models and localized, national and international actions. The case studies can be seen as frequently fitting within strategies that have been proven to work in reducing ageism within the workplace. They include policy and laws that have increased benefits to workers during lockdowns (most countries); educational activities such as coaching seniorpreneurship (e,g, Australia); intergenerational contact interventions such as younger Thai people who moved back to rural areas and sharing their digital knowledge with older people and where older people reciprocate by teaching the younger people farming knowledge. CONCLUSION: Global sharing of this knowledge among international, national and local governments and organizations, businesses, policy makers and health and human resources experts will further understanding of the issues that are faced by older workers. This will facilitate the replication or scalability of solutions as called for in the WHO call to combat ageism in 2021. We suggest that policy makers, business owners, researchers and international organisations build on the case studies by investing in evidence-based strategies to create inclusive workplaces. Such action will thus help to challenge ageism, reduce inequity, improve business continuity and add to the quality of life of older workers.

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.

Thereby, state-of-the-art software solutions attempt to streamline the design and production processes accordingly. However, most digital workflows lack in terms of adequate sequential data preparation, agglomeration, and interfacing capabilities for consecutive design phases. These issues result in long, tedious correction loops, a wide range of software solutions and extensions to mitigate the issues. In addition, many digital workflows do not consider or integrate construction, production and machine relevant data holistically (respectively geometry and semantics). In this context, the production relevant data in from of human-centered work process data referring to digital human models (DHM), derived human abilities, safety and ergonomic criteria are often neglected. However, this is essential to interface the construction, human and machine relevant data in a holistic manner. This paper therefore proposes a DtP-workflow which is intended to solve some of the issues by interfacing relevant software solutions incorporating construction, production (including DHM and more) and machine relevant data in a holistic manner using a Building Information Modeling (BIM)-approach (based on the IFC schema). In this regard, the DtP-workflow aims to reverse common top-down digital workflows by considering and integrating the relevant data for consecutive design phases from the beginning. Subsequently, the DtP-workflow should achieve a reduction in planning effort.

CO2-Emissionen, die bei der Zement- und Betonherstellung an-fallen, müssen reduziert, Produktionsmethoden verbessert und Betonzusammensetzungen angepasst werden. Zudem steigt die Nachfrage nach Beton, während fossile Brennstoffreserven und die Verfügbarkeit von mineralischen Rohstoffen abnehmen. Hinzu kommt, dass bei der Betonherstellung neue mineralogi-sche Phasen entstehen, was ein echtes Recycling erschwert. Die Implementierung kreislaufkonformer Strategien wie der Verlängerung der Nutzungsphase ist ein wichtiger Hebel, um Umweltwirkungen im Bauwesen zu reduzieren, und erfordert die ganzheitliche Betrachtung des Bauwerks. Besonders großes Potenzial liefern hier die digital vernetzte und modellba-sierte Planung sowie die darauf aufbauende robotergestützte Fertigung der Bauteile, mit der sich leicht lösbare Verbindun-gen, einfach rückbaubare, multifunktionale, flexible sowie bzgl. Dauerhaftigkeit optimierte Strukturen ökologisch und kosten-effizient generieren lassen. Technisch wären bereits viele Pro-jekte in der Praxis umsetzbar, allerdings müssen hierzu die rechtlichen Rahmenbedingungen verbessert und bürokratische Hürden abgebaut werden. Dieser Beitrag hat das Ziel, das Be-wusstsein für den nötigen Wechsel von der Linear- zur Kreis-laufwirtschaft im Betonbau und den korrespondierenden Daten zu erhöhen und dem Planer einfache Grundsätze für den Ent-wurf, die Ausschreibung und Umsetzung mitzugeben, um jetzt schon einen wichtigen Beitrag zum verantwortungsvollen Um-gang mit immer knapper werdenden Ressourcen zu leisten.

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.

Simultaneously, the industry experiences one of the lowest degrees of digitalization. In this context, cyber-physical education is essential to empower learners with skills to utilize digital and physical solutions more effectively. Therefore, a modular as well as construction specific learning setting was designed. The setting facilitates a range of topics, such as production planning considering human and robot capabilities, (semi-) automated construction machines, robotics, sensing & actuation and more. The digital part of the cyber-physical toolbox consists of various methods and tools to learn programming languages, frameworks, offline simulators, post-processors and more. This step is essential to enable an end-to-end data-/workflow from design (e.g., BIM-based planning methodologies) to (machine-based) production. A focus is given to human-machine/-robot collaboration and appropriate simulation tools (e.g., emaWD) enabling the incorporation of human factors. The physical setting is highly modular, and each device and its periphery can be customized to a broad variety of learning scenarios and levels. This paper describes the details of the learning setting, extracts learning strategies, and analyzes selected learning scenarios and their initial testing in various learning formats.

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.

This paper therefore introduces a methodological framework aiming to address the industry's pressing need for a systematic approach for assessing the feasibility of integrating robotics into human-centered construction processes. It aims to enhance decision-making regarding the degree of automation in human-centered construction processes, ranging from partial to full robotization or non-robotization. The framework is characterized by a more holistic end-to-end data-/workflow and therefore adopts a multifaceted approach, leveraging BIM-based planning methodologies and integrating new technologies [e.g., Motion Capturing (MoCap), work process simulation software incorporating Digital Human Models (DHM), self-developed conversion/interfacing software and more] that have not been widely used in the industry to date. Subsequently, the framework is evaluated in a real-life bricklaying construction process to ensure a more application-based approach. Overall, the framework advances current construction processes with a more inclusive and conscious technology infill to empower construction professionals with the workflow and corresponding tools necessary for the practical integration of robotics into human-centered construction processes.
