Lean Construction (LC) has been implemented worldwide in different construction projects, and the Covid-19 pandemic has been no exception. However, more research needs to be compiled on the benefits of LC during this period, considering the high variability and uncertainty generated. Therefore, this article evaluates the benefits of implementing LC during the pandemic stage. In the first stage, a literature review was conducted using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), where the main benefits of implementing Lean Construction during the pandemic are identified. In the second stage, the benefits were validated through interviews with professionals in different Peruvian construction projects. The main benefits were: improved planning, easier identification of constraints, and improved project communication. The following study will help construction industry professionals consider LC implementation's benefits in future scenarios with high variability.

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.

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.

In recent years, Construction 4.0 has integrated Industry 4.0 technologies into the construction sector, with robots playing a key role in improving productivity and safety. However, few studies address strategies for implementing robots in specific contexts, particularly in developing countries. This study proposes a roadmap for robot implementation in the Peruvian construction sector. It identifies barriers and benefits and then validates the roadmap through expert consultation. The roadmap consists of four phases: aligning the company, evaluating technology, planning implementation, and executing while assessing practices. This provides valuable guidance for construction companies adopting robotic technology.

Robotics is a key component of Construction 4.0 and has gained increasing attention in construction projects. However, previous studies have mainly focused on technological development, with limited analysis of the perceived challenges and benefits among industry stakeholders. This study examines these aspects in the Peruvian construction sector. A literature review was conducted to identify potential challenges and benefits, which were validated by six experts, resulting in 11 benefits and 13 challenges. A survey was then administered to construction professionals, and the data were analyzed using Cronbach’s coefficient, Relative Importance Index (RII), and Exploratory Factor Analysis (EFA). The results show that the main challenges include weak innovation culture, limited investment capacity, and complex technological requirements. The most significant benefits are improved efficiency through automation and digital interoperability, continuous improvement through industrialized production, and enhanced organizational competitiveness. These findings highlight the importance of strengthening innovative culture, developing regulatory frameworks, and adapting implementation strategies to promote robotics adoption in the construction industry.
