Respect for People (RFP) is a crucial element in Lean Construction philosophy, along with continuous improvement. However, despite its importance, research on RFP is still limited. Therefore, the following article aims to identify good practices, benefits, and barriers generated by its implementation on the construction site. The research begins with a literature review, following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria. Subsequently, with the list of good practices, benefits, and barriers, nine lean experts were interviewed, validating the information obtained from the literature review. This process identified eleven good practices, eleven benefits of implementing RFP in construction projects, and nine barriers. The upcoming research will serve as a valuable contribution for professionals seeking to implement good practices of RFP on the construction site and researchers aiming to delve deeper into this concept.
In the field of technological construction tools, 360-degree panorama provides a panoramic virtual reality capable of representing the construction environment in great detail. While there are many studies on their pedagogical and safety applications, few studies address the benefits of their use in construction monitoring and control. For this reason, the present research aims to explore its application and benefits for monitoring and control, the research for which begins with a literature review of the application of 360-degree panoramas in construction, where the authors identified the main benefits. In the second stage, the authors analyzed two case studies of its application: the first is based on the construction of a retail project, and the second is based on an infrastructure project. After the implementation, the researchers conducted interviews with the team members responsible for implementing 360-degree panorama. The main benefits of 360-degree panorama are as follows: a complete overview of the construction site situation, verification of the distribution of the space used, documentation of the current project situations, as well as progress control and quality control. These results will hopefully help to improve the understanding of this tool’s current state of the art in the construction field and open the door to future investigations on cost–benefit analysis that facilitate the application of this tool in construction sites.
The construction industry is a critical sector in the economy of countries; however, it has low productivity and is associated with errors and rework. In response, poka yoke or mistakeproofing devices have been developed to avoid errors or reduce the possibility of committing them. Their application has been documented in manufacturing and, to a lesser extent, in the construction sector, where the literature on this subject is scarce. Therefore, the following article aims to develop a literature review of poka yoke in the construction sector. To this end, a literature review was conducted using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis). Twenty-five articles related to poka yoke were analyzed. From the literature review, it was obtained that the main poka yoke found corresponds to the principle of facilitation; the main benefits reported were improvement of quality and performance and reduction of errors, and the main barrier is the lack of training on the subject. The following article will contribute to professionals and researchers in the construction sector to have a better understanding of the applications of poka yoke.
In recent years, the construction sector has been influenced by different technologies, which has given way to construction 4.0. One of the elements of Construction 4.0 is the use of artificial intelligence, and in recent years, chatbots have become popular in different industries, including construction. However, the literature on how chatbots can help in construction projects is limited. In this sense, the following article aims to study the degree of reliability presented by a chatbot (ChatGPT) to improve the implementation of the Last Planner® System (LPS). This article begins with a literary review of LPS barriers. From this, 13 main barriers are validated with the help of 10 expert judgments. After that, ChatGPT 3.5 is interacted with to provide possible solutions to the barriers found, which are validated again with eight expert judgments. The results show that 68.27% of ChatGPT responses are "Totally agree" and "Somewhat agree." The following article will contribute to professionals in the construction sector so that they can evaluate the reliability of chatbots and explore their applications to solve LPS implementation problems and other problems in construction projects.
The construction industry faces a number of challenges, including cost increases, schedule delays, and dissatisfied customers. The Virtual Design and Construction (VDC) methodology has emerged as a response to this. However, there is a research gap on the applications and results of VDC specifically in hospital projects. This study focuses on how the implementation of VDC influenced the results of the hospital project in the construction phase and its monitoring through metrics, using on-site observations, document analysis, and unstructured interviews as sources of evidence. Among the results, a 22% reduction in the time for dismantling the tower crane was achieved, a 24% reduction in the time for constructing the structural shell, and a saving of 25,000-man hours in the formwork, steel, and concrete items. In addition, the safety goal of zero accidents was met.
This research addresses the critical need to study human capital and organizational design in the construction industry. To overcome the scarcity of literature on the functionality and responsiveness of organizational charts, this study carries out a comparative analysis of large-scale construction projects in Chile and Peru. Using a multiple-case study approach and a Complex Adaptive Systems (CAS) framework, the research examined how organizational structures configure and adapt to local contexts through semi-structured interviews, exploring the influence of external factors such as regulations, the market, and culture on the design of organizational charts. The results reveal that while Peruvian structures tend toward centralization influenced by cultural factors, Chilean structures exhibit greater horizontality. Furthermore, Lean philosophy emerged as a key contextual factor that facilitates organizational adaptability in complex environments. The study concludes that organizational adaptability is not merely a product of formal design, but an emergent property driven by the interaction between formal roles and management practices. These findings contribute to a deeper understanding of how construction firms can configure their structures to better respond to project complexity. For future research, it is proposed to explore the correlation between the complexity of organizational charts and project performance, using quantitative and qualitative indicators, and analyzing the evolution of organizational structures throughout the project life cycle. In addition, it is suggested to investigate the impact of digitalization and agile methodologies, as well as to conduct longitudinal studies to assess the resilience and adaptability of organizational charts to regulatory and market changes.
