    Use of Value Stream Mapping in a Case Study in Basement Construction
    (Pontificia Universidad Católica del Perú. Facultad de Arte y Diseño, 2021) Espinoza, Lisseth R.; Herrera, Rodrigo F.; Brioso, Xavier; Pontificia Universidad Católica del Perú
    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) Espinoza, Lisseth R.; Brioso, Xavier; Herrera, Rodrigo F.; Pontificia Universidad Católica del Perú
    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.
