    Use of Value Stream Mapping in a Case Study in Basement Construction
    (Pontificia Universidad Católica del Perú. Facultad de Arte y Diseño, 2021)
    The Value Stream Mapping (VSM) as a management tool helps evaluate the waste within the workflow. However, it must be adapted to the construction since it was originated in manufacture. This adaptation is possible through appropriate process mapping. This study aims to map the process of the basement construction system in the execution of a building in Lima-Peru city. The building in the case study will have nine basements and 11-floor levels. An adaptation of the optimization cycle for construction projects was used. It allows mapping all the relevant activities and proposing and implementing improvements in the construction system. As a result, three maps were obtained. The first one is a map of the current state (VSM 1). The second one is a map of the current state with improvements (VSM 2). Finally, a third map of the future state with improvements (VSM 3). This study demonstrated that it is possible to adapt the VSM in basement construction and the usefulness of this tool to evaluate and reduce waste within the workflow.

    Applying CBA to Decide the Best Excavation Method: Scenario During the Covid-19 Pandemic
    (Pontificia Universidad Católica del Perú. Facultad de Arte y Diseño, 2021)
    On January 30 of 2020, The World Health Organization declared the pandemic crisis as the first public emergency with international importance. Because of this, many building projects were paralyzed since then and the building industry experienced changes that have brought the inclusion of new tools to achieve the objectives of the projects. The purpose of the present paper is to present the application of Choosing By Advantages (CBA) methodology to select the best alternative in the material removal system in the execution of basements in a project that was paralyzed by the health emergency COVID 19. CBA is a lean tool used to make decisions with clarity and transparency and in this case is used to consider the constraints of COVID-19 protocol to guide in decisions making. This methodology was applied to a case study for a building project in the basement construction phase that restarts its activities in the excavations. For that, an expert panel was formed to analyze and decide the best alternative solution. Finally, the selected alternative was implemented on-site, validating the methodology. It is concluded that CBA is an excellent tool to transparently document the selection process of the removal system. Additionally, this methodology allows including activities regarding the COVID-19 protocol, without affecting the project's productivity.

    Simulations for teaching construction management: a systematic literature review
    (Emerald Publishing, 2025-01-01)
    Purpose – Simulations have been explored and used as effective educational tools to support active learning. However, despite the increasing adoption of simulation-based learning, there is a need for the design of comprehensive simulations that can support the acquisition of a range of competencies linked to the current construction industry demands. With an aim of determining the current situation, this study conducts a systematic literature review (SLR) on simulations for teaching construction management to undergraduate students. Design/methodology/approach – The articles were selected through a systematic literature review following the PRISMA guidelines, and utilizing Scopus and Web of Science databases. Findings – This study shows that a total of 94 simulations were identified from the literature and can be categorized in terms of their composition by virtual, real or virtual and real elements. The majority of the simulations have been designed with virtual elements. This study shows that 22 competencies and skills were developed in the 94 simulations. Also, the most frequent competencies and skills developed are not aligned with the most valued, according to construction professionals. Furthermore, most simulations currently implemented focus on development, often limited to technical aspects. In addition, this study shows that simulation evaluation should be generally improved. Practical implications – The findings from this review would help researchers, simulation developers and construction management developers identify the current situation of simulations in terms of their composition, validation and competencies linked to digitalization, sustainability and human-centered skills, particularly relevant in the emerging paradigms of Construction 4.0 and 5.0. This review also suggests that to improve simulation designs, future studies should apply more rigorous experimental designs, integrate real-time feedback mechanisms and validate simulation outcomes across different institutional and cultural contexts. Originality/value – This study undertakes a comprehensive SLR of studies about teaching construction management to undergraduate students published in the past 30 years, which indicate the latest trends. It is the first attempt internationally to provide a description of the current situation of simulations in terms of their composition, validation and competencies linked to the current construction industry demands.
