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.

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.}, language = {en} } @inproceedings{ChenPanLinneretal., author = {Chen, Tianxi and Pan, Mi and Linner, Thomas and Zhong, Honghao}, title = {Development of Robotics for Building Exterior Inspection: A Literature Review}, series = {Proceedings of the 41st International Symposium on Automation and Robotics in Construction, Lille, France, June 3-5, 2024}, booktitle = {Proceedings of the 41st International Symposium on Automation and Robotics in Construction, Lille, France, June 3-5, 2024}, editor = {Gonzalez-Moret, Vicente and Zhang, Jiansong and Garc{\´i}a de Soto, Borja and Brilakis, Ioannis}, publisher = {IAARC}, doi = {10.22260/ISARC2024/0139}, abstract = {The aging of buildings is a global concern, with potential risks to human safety and property.

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.

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.

In diesem Beitrag wird daher das Forschungsprojekt (BMBF-Projekt) ReduSys (Akronym: Kontaktreduzierte Pflege im klinischen Umfeld durch multimodale Systeme und Robotik) vorgestellt und die sozio-technischen Entwicklungen im Kontext der Nachhaltigkeit er{\"o}rtert. ReduSys strebt eine ganzheitliche Systeml{\"o}sung an, welche bestehend aus verschiedenen Technologien (z. B. Sensorik, IoT, Robotik VR etc.) den {\"U}bergang von der herk{\"o}mmlichen zur kontaktreduzierten Pflege (z. B. bei pandemischen Situationen wie der Covid-19 Pandemie) erm{\"o}glichen soll. Durch den Technologieeinsatz (z. B. kontaktlos-kontinuierliche Vitalparametererfassung via Medical Smart Bed oder humanoide Robotik via ‚Robody' etc.) sollen Pflegekr{\"a}fte nachhaltig entlastet und gleichzeitig eine bessere Patientenf{\"u}rsorge gew{\"a}hrleistet werden. In diesem Zusammenhang bildet die Fakult{\"a}t Bauingenieurwesen mit dem ‚Building Lab/Digitales Bauen' an der OTH Regensburg die Schnittstelle zwischen gebauter Umwelt und den eingesetzten digitalen und robotischen Technologien. Dar{\"u}ber hinaus wird der Systemansatz durch die weiteren Projektpartner komplementiert und kontinuierlich praxisnah validiert, um eine m{\"o}glichst integrative Systeml{\"o}sung zu gew{\"a}hrleisten. In diesem Beitrag wird auf die Entwicklung digitaler, als auch modularer Technologie als ‚Infill' f{\"u}r Geb{\"a}ude bzw. M{\"o}bel seitens der OTH Regensburg eingegangen, um veranschaulichen zu k{\"o}nnen, wie mit gezielten technologischen Eingriffen ein signifikanter Mehrwert f{\"u}r die klinische bzw. pflegerische Umgebung geschaffen werden kann und simultan Aspekte der {\"o}kologischen, sozialen, wie auch wirtschaftlichen Nachhaltigkeit in die technische Entwicklung miteinfließen k{\"o}nnen}, language = {de} } @incollection{BiersackSchmailzlLinneretal., author = {Biersack, Stefan and Schmailzl, Marc and Linner, Thomas and Eder, Friedrich and Obergrießer, Mathias}, title = {Von der Handarbeit zur Hochtechnologie im Reallabor: Die M{\"o}glichkeit der BIM-basierten Planung und effizienten Produktion von Ziegelw{\"a}nden durch Roboter}, series = {Mauerwerk-Kalender 2025}, volume = {2025}, booktitle = {Mauerwerk-Kalender 2025}, editor = {Schermer, Detleff and Brehm, Eric}, edition = {1.

By integrating process design with AI-based algorithms into simulation tools, various construction process layout variants including robot-assisted scenarios can be simulated and evaluated based on user-specific key performance indicators (e.g., ergonomic score, layouting parameters) to identify optimized solutions. A data processing algorithm automates the process, eliminating the need for manual simulation variations and resulting in increased operational productivity. The AI-based system evaluates and optimizes process layouts by adjusting control parameters. A case study on a brick laying process serves as an exemplary use case, highlighting the necessity and impact of adopting process optimization.

Solutions for on-site drilling, spraying, masonry, logistics, and finishing are now being piloted at an unprecedented pace. Their deployment in emerging construction robotics hubs in Singapore, Hong Kong, Canada, Dubai, Abu Dhabi, Egypt, Denmark, Switzerland, and Germany demonstrates both the momentum of this technological shift and the considerable challenges that remain. In real-world testing environments, the integration of these robots into digital construction pipelines—particularly BIM-to-robot workflows, semantic task modeling, and robust digital twins—continues to be a bottleneck. These challenges position digitally enabled fabrication and robotics as a priority topic within academia, motivating research on methods, techniques, algorithms, and workflows that can accelerate adoption in construction. This Topical Collection brings together research spanning the emerging landscape of digitally enabled construction robotics. The contributions advance robotic fabrication, from flexible timber processes to innovative formwork, reinforcement, and earth-based additive methods, alongside computer vision, BIM integration, and sensing approaches that improve monitoring and quality assurance. The collection also includes mobile and aerial systems for inspection and mapping to support system autonomy in construction. Together, these works show how integrated perception, planning, and sociotechnical understanding of human-robot collaboration are becoming essential for reliable robotic performance in construction. While current construction robots still focus on simple, structured tasks, the advances in this topical collection point toward a more capable generation. Contributions outline principles for robot-compatible buildings through new fabrication logics and BIM-linked task data, while work on perception, BIM integration, and data fusion reduces interoperability gaps. Research on sensing and adaptive processes supports more consistent workflows, and mobile and aerial robotics provide insights for deployment and site logistics. Collectively, these developments show how digitally enabled production processes can help to overcome key systemic barriers and enable future, scalable construction robotics.}, language = {en} }
