Concrete 3D printing offers several significant advantages, including the ability to create complex geometries, increased material efficiency, faster build times and cost savings. These are particularly important in the context of the current skilled labour shortage and emphasis on resource efficiency in construction. Nevertheless, challenges persist in the areas of machine reliability, process integration, and material adaptation to meet the requirements of 3D printing. The case studies will present modular and design-engineering-based strategies for the development of efficient, scalable automation solutions that integrate 3D printing into existing processes and allow for project-specific customisation through selective automation. These findings provide a robust framework for industrial applications that enhance efficiency and adaptability. By comparing concrete 3D printing to conventional methods, the insights offer a foundation for advancing automated production in construction, promoting scalable, resource-efficient, and economically sustainable practices that address the industry’s evolving demands.

Sustained physical activity matters greatly to the health and well-being of older people and significantly improves their chance of maintaining independent living. It can make a difference across the whole care continuum as well as in almost every setting. Therefore, REACH solutions focus on the systematic, target-oriented increase of physical activity of older people, and tackle the whole prevention spectrum (primary, secondary, and tertiary). It seeks to empower older people and their formal and informal caregivers, and works towards viable solutions for both the formal and in-formal care sector. Technology-based personalization of prevention, activation, and care services provided in various living and care settings is at the center of the developed solutions. Ideally toolkit approach would allow for the tailoring of solutions that create value for end-users, care providers and health care payers alike through the combination, integration and adaptation/re-design elements towards the different contexts of different countries, different payment and reimbursement structures. This Special Issue sheds light on such solutions, their conception, their development, and their testing.

Many enablers have been identified across various studies; however, a comprehensive synthesis defining the enablers of design for digital fabrication does not yet exist. This work conducts a systematic literature review of 59 journal articles published in the past decade and identifies 140 enablers under eight categories: actors, resources, conditions, attributes, processes, artefacts, values and risks. The enablers’ frequency network is illustrated using an adjacency matrix. Through the lens of actor-network theory, the work creates a relational ontology to demonstrate the linkages between different enablers. Three examples are presented using onion diagrams: circular construction focus, business model focus and digital twin in industrialisation focus.

The research addressed the question of whether the CDPR was capable installing CWMs with sufficient accuracy while being competitive compared to conventional manual methods. In order to develop and test such a system, a conceptual framework that consisted of three sub-systems was defined. The tests, carried out in two close-to-real demonstration buildings, revealed an absolute accuracy of the CWM installation of 4 to 23 mm. The working time for installing a CWM was reduced to 0.51 h. The results also show that the system is competitive for a workspace greater than 96 m2 compared to conventional manual methods. However, improvements such as reducing the hours for setting up the CDPR on the one hand and achieving a faster and more robust MEE on the other hand will be still necessary in the future.

Most of the accidents are associated with the presence of maintenance personnel in the working area during programming, configuration, training, repair and maintenance of robots. The article describes measures to ensure safety during the maintenance of robots and manipulators. The stages of preparing the construction industry for the use of manipulators, robots and robotic complexes are presented. A system of measures for preparing equipment for use and its maintenance during operation is proposed.

However, there is still a gap in the ubiquitous application of STCRs for onsite construction due to various reasons, such as cost concerns. Therefore, cost–benefit analysis (CBA) can be used to measure the net economic benefit of the STCRs, compared to traditional construction methods, in order to boost the implementation of STCRs. This paper presents a simple and practical framework for the economic evaluation of STCRs and conducts a case study of a cable-driven facade installation robot to verify the method. The results show that the cable-driven robot for facade installation is worth investing in in the UK, as well as in the majority of G20 countries. Furthermore, other socioenvironmental implications of STCRs and the limitations of the study are also discussed. In conclusion, the proposed method is highly adaptable and reproducible. Therefore, researchers, engineers, investors, and policy makers can easily follow and customize this method to assess the economic advantages of any STCR systems, compared to traditional construction technologies.

Recent scholars study design for automation to facilitate robotization in design and planning. Besides, it has the potential to enable circularity to assist in the current resource crisis. This article explores how robotization can foster the circular built environment with design for fabrication, assembly and disassembly in current practice. This article first presents the industry adoption of robotization through design for fabrication, assembly and disassembly (Design for X) and Robot-Oriented Design (ROD) in Japan and abroad. Secondly, based on the concept of ROD, this work investigates how this fosters the circular built environment through industry review and literature review. It is concluded with three takeaways of robotization for the circular built environment with ROD and future directions in research. The work contributes to the body of knowledge in automation in construction, construction management, technology and innovation.

Current solutions for installing and fitting prefabricated modules on existing buildings are time consuming. The objective of this research is to reduce the time currently required for the installation of timber-based 2D modules by using innovative technologies while improving placement accuracy. A novel installation concept was proposed based on a digitally produced matching kit interface that corrects existing building’s irregularities and connector placement deviations. This solution was tested, validated, and compared in several manufacturing contexts. The tests recorded measurable variables such as the manufacturing time and placement accuracy of the modules. The results demonstrate decreases up to 73% in installation time and placement deviations of less than 2 mm.

The report presents the outcome of an identification and detailing of user acceptance and motivation strategies for the overall system (REACH, Touchpoints & Engine concept) and subsystems (Touchpoints, REACH toolkit elements), providing full consideration and detailing of ethical, privacy, legal and usability/accessibility aspects. The REACH system incorporates two strands of technological elements; on the one hand, sensing and monitoring elements, and, on the other hand, motivational and physical engagement elements. For both types, user acceptance is critical allowing for a user experience that leads to (intrinsic, extrinsic, etc.) motivation to more physical activity. The remainder of this Deliverable is structured as follows. First, we introduce the REACH-specific interplay of the concept “user acceptance” with the linked concepts “behaviour change/motivation” and “personalization” in the context of (early) physical activation of elderly persons, and outline the related work and activities conducted in REACH (overall and per TP). Second, we present an analysis and structuring of acceptability drivers (ethical, privacy/security, legal, and accessibility considerations) per Touchpoint. From this we developed an integrated view that represents REACH specific know-how about how to use these acceptability drivers to integrate advanced ICT-driven technology for early detection and intervention use cases seamlessly into age inclusive communities. Third, we present our findings in the context of the development of acceptability drivers for the use of sensing and monitoring elements. We conclude the deliverable by outlining acceptability related evidence and examples from REACH trials (based on Deliverable D27 findings), and by summarizing the overall findings of this deliverable.
