Title: Perceptions of 3D Printing Construction Adoption in Latin America: Opportunities, Barriers, and Strategies for Sustainable Infrastructure
Within Architecture, Engineering, and Construction (AEC), 3D Printing Construction (3DPC) offers significant potential by facilitating design flexibility, reducing reliance on formwork, and enhancing sustainability. However, the broader adoption of 3DPC is hindered by critical challenges, including lack of standards, material properties, and extra costs associated with a high initial investment. While previous studies have already explored the opportunities and barriers regulating the adoption of this technology from the perspective of a developed country, there is a critical need to better understand its potential in developing nations. This research aims to identify the AEC community's perception of 3DPC across four key dimensions: opportunities, barriers, strategies, and potential applications. Using a structured questionnaire, the perspectives of 341 construction professionals from developing regions were analyzed to comprehensively assess the feasibility and potential impact of 3DPC in these contexts, informing future strategies for effective implementation. This research contributes to understanding how 3DPC can revolutionize construction practices in developing countries, promoting sustainable and efficient infrastructure development.  more » « less

  1. This study aimed to investigate the key technical and psychological factors that impact the architecture, engineering, and construction (AEC) professionals’ trust in collaborative robots (cobots) powered by artificial intelligence (AI). This study seeks to address the critical knowledge gaps surrounding the establishment and reinforcement of trust among AEC professionals in their collaboration with AI-powered cobots. In the context of the construction industry, where the complexities of tasks often necessitate human–robot teamwork, understanding the technical and psychological factors influencing trust is paramount. Such trust dynamics play a pivotal role in determining the effectiveness of human–robot collaboration on construction sites. This research employed a nationwide survey of 600 AEC industry practitioners to shed light on these influential factors, providing valuable insights to calibrate trust levels and facilitate the seamless integration of AI-powered cobots into the AEC industry. Additionally, it aimed to gather insights into opportunities for promoting the adoption, cultivation, and training of a skilled workforce to effectively leverage this technology. A structural equation modeling (SEM) analysis revealed that safety and reliability are significant factors for the adoption of AI-powered cobots in construction. Fear of being replaced resulting from the use of cobots can have a substantial effect on the mental health of the affected workers. A lower error rate in jobs involving cobots, safety measurements, and security of data collected by cobots from jobsites significantly impact reliability, and the transparency of cobots’ inner workings can benefit accuracy, robustness, security, privacy, and communication and result in higher levels of automation, all of which demonstrated as contributors to trust. The study’s findings provide critical insights into the perceptions and experiences of AEC professionals toward adoption of cobots in construction and help project teams determine the adoption approach that aligns with the company’s goals workers’ welfare.

  2. Exoskeletons and exosuits (collectively termed EXOs) have the potential to reduce the risk of work-related musculoskeletal disorders (WMSDs) by protecting workers from exertion and muscle fatigue due to physically demanding, repetitive, and prolonged work in construction workplaces. However, the use of EXOs in construction is in its infancy, and much of the knowledge required to drive the acceptance, adoption, and application of this technology is still lacking. The objective of this research is to identify the facilitators, barriers, and corresponding solutions to foster the adoption of EXOs in construction workplaces through a sequential, multistage Delphi approach. Eighteen experts from academia, industry, and government gathered in a workshop to provide insights and exchange opinions regarding facilitators, barriers, and potential solutions from a holistic perspective with respect to business, technology, organization, policy/regulation, ergonomics/safety, and end users (construction-trade professionals). Consensus was reached regarding all these perspectives, including top barriers and potential solution strategies. The outcomes of this study will help the community gain a comprehensive understanding of the potential for EXO use in the construction industry, which may enable the development of a viable roadmap for the evolution of EXO technology and the future of EXO-enabled workers and work in construction workplaces.

    Effective construction engineering and management education requires hands-on experiences that have not traditionally been offered in classroom settings. Physical building competitions like Solar Decathlon are valuable for providing experiential learning opportunities that may support tacit and explicit knowledge development among students, but they are often not available to all students due to funding and resource limitations. Less resource intensive teaching strategies, such as project based learning, can mimic the benefit of physical experiences by providing context to learning content. This paper reviews project based learning literature to identify trends in reported learning gains from the adoption of this strategy. Additionally, emerging technologies offer the ability to create low cost, immersive multimedia environments that may be able to support the types of learning targeted by physical design and construction experiences. Literature on multimedia learning theory is explored to identify opportunities for multimedia applications to facilitate learnings derived by physical educational contexts, but with the use of increasingly affordable multimedia strategies. This paper resulted in identifying six learning gains that have a theoretical potential to be facilitated using augmented reality and virtual reality technologies. The theoretical potential was deduced based on prior research on teaching strategies that provide real-world context to learning content. The authors of this paper propose using the identified learning gains as targets to specifically design implementation studies to verify this potential. The learning gains identified in the results section can be targeted and measured in future research when empirically validating the use of immersive technologies for construction education. The contribution of this work is in synthesizing the learning gains that future researchers should target based on evidence from prior research in related learning contexts.

    Nascent Professional Identity Development in Freshman Architecture, Engineering, and Construction (AEC) Women Increasing the persistence of talented women into male-dominated architecture, engineering, and construction (AEC) professions could reduce prevailing workforce shortages and improve gender diversity in AEC industry. Identity theorists advocate that professional identity development (PID) improves students’ persistence to become professionals. However, little empirical research exists to inform and guide AEC educators and professionals on AEC-PID in undergraduate AEC women. As the preliminary part of a larger nationwide and longitudinal research study investigating PID processes in undergraduate AEC women, the objective of this research is to examine the characteristics and nascent AEC-PID in 69 women enrolled in freshman AEC courses in five U.S. institutions. A purposive sampling approach ensures participants have a wide range of demographic characteristics. Data from a recruitment survey is analyzed using the NVivo qualitative data analysis software. Content and relational inductive open coding are conducted vertically for each participant and horizontally across different participants. Results indicate passion/interest, inherent abilities, significant others, benefits from industry, and desire to contribute to industry influence decisions to pursue AEC careers. With 52% of participants having science, technology, engineering, art, and math (STEAM) subject preferences, an in vivo code, Perfect Middle Ground, demonstrated the quest to combine STEM and visual art preferences in AEC career decisions. A participant noted that ‘this major (civil engineering) is the perfect middle ground because I can be creative, but still use my strong gift which happens to be math’. Girls with STEAM strengths and passion, particularly in math and fine art, are most likely to develop nascent AEC-PID. Beyond STEM pre-college programs, AEC educators should consider recruiting from sports, as well as visual and performing arts events for pre-college students. Participants’ positive views focus on the importance and significant societal impact of the AEC industry; while, negative views focus on the lack of gender and racial diversity. A combination of participants’ AEC professional experiences and views reveal four increasing levels of nascent AEC-PID which are categorized as the 4Ps: Plain, Passive, Progressive, and Proactive. As a guide to AEC education and professional communities, recommendations are made to increase the AEC-PID of women in each category. With the highest nascent AEC-PID, women in the Proactive category should serve as leaders in AEC classrooms and student organizations. Considering their AEC professional experience and enthusiasm, they should serve as peer mentors to other students, particularly AEC women. Furthermore, they should be given the opportunity to step into more complex roles during internships and encouraged to pursue co-op opportunities. Insights can guide more targeted recruitment, mentoring, preparation, and retention interventions that strengthen the persistence of the next generation of AEC women professionals. In the long term, this could reduce AEC workforce shortages, improve gender diversity, and foster the innovation and development of more gender friendly AEC products and services.
