“…Thereafter, a second preliminary step (i.e., Step 2) was conducted that consisted of the BIM modelling. The BIM modelling, which is described in Santa Cruz et al [42], served as the benchmark to obtain the quantity take-off (i.e., bill of materials) that was used in the study. This leads, already within the current operational framework, to the definition of additional criteria in the MCDM (Step 3a) through the participation of stakeholders, but also to a clear computation of the foreground system in the life cycle inventory (LCI) in the LCA (see Step 3b).…”

“…Recent efforts by the Peruvian government, however, are trying to reduce the vulnerability of these infrastructures by drawing up an ambitious plan to retrofit these schools to withstand big earthquakes [42]. For this, three different low-cost incremental seismic rehabilitation (ISR) techniques (i.e., steel, concrete and masonry) were developed, all of which were validated in previous studies in terms of seismic resistance and economic values [38,43].…”

“…Data were gathered from an array of bibliographical sources. Having said this, an important portion of the primary data were obtained from the BIM 3D model, as described in Santa-Cruz et al [42]. This allowed using automated and auditable high-accuracy estimations of the quantity take-off needed for the three ISR techniques.…”

Building information modeling (BIM) is an emerging technology that improves visualization, understanding, and transparency in construction projects. Its use in Latin America and the Caribbean (LA&C), while still scarce, is developing in combination with multi-criteria decision-making (MCDM) methods, such as the choosing by advantages (CBA) method. Despite the holistic nature of MCDM methods, the inclusion of life cycle environmental metrics is lagging in construction projects in LA&C. However, recent studies point toward the need to optimize the synergies between BIM and life cycle assessment (LCA), in which a method like CBA could allow improving the quality of the decisions. Therefore, the main objective of this study is to integrate LCA and CBA methods to identify the effect that the inclusion of environmental impacts can have on decision-making in public procurement, as well as comparing how this final decision differs from an exclusively LCA-oriented interpretation of the results. Once the LCA was performed, a set of additional criteria for the CBA method were fixed, including transparency, technical, and social indicators. Thereafter, a stakeholder participative workshop was held in order to gather experts to elucidate on the final decision. The methodology was applied to a relevant construction sector problem modelled with BIM in the city of Lima (Peru), which consisted of three different construction techniques needed to retrofit educational institutions. Results from the LCA-oriented assessment, which was supported by Monte Carlo simulation, revealed a situation in which the masonry-based technique showed significantly lower environmental impacts than the remaining two options. However, when a wider range of technical, social, and transparency criteria are added to the environmental indicators, this low-carbon technique only prevailed in those workshop tables in which environmental experts were present and under specific computational assumptions, whereas teams with a higher proportion of government members were inclined to foster alternatives that imply less bureaucratic barriers. Finally, the results constitute an important milestone when it comes to including environmental factors in public procurement in LA&C.

El objetivo de este trabajo es mostrar las técnicas efectivas empleadas para enseñar construcción de edificaciones en el tercer año de un programa de la carrera de ingeniería civil de la Pontificia Universidad Católica del Perú. Este enfoque implicó integrar plataformas virtuales y software para realizar videoconferencias y laboratorios en las que se utilizan herramientas como Building Information Modeling (BIM) y Lean Construction, entre otras. Esta metodología balanceada sirve como un modelo exitoso para impartir conocimientos sobre la construcción de edificaciones. Las visitas a obra se simularon mediante recorridos virtuales creados con la tecnología scanner laser, fotogrametría y BIM. Los gemelos digitales generados se colocaron en plataformas en línea y los estudiantes recorrieron interactivamente el proyecto de construcción. Adicionalmente, los estudiantes desarrollaron planos de layout utilizando modelos BIM 3D y 4D. Durante la asignatura también se instruyó a los alumnos en el análisis de precios unitarios y en las mediciones de las actividades de obra a través de la metodología BIM con software 5D, teniendo como resultado el desarrollo de los presupuestos. La efectividad de esta metodología se evidencia en la alta calidad de los trabajos académicos, evaluaciones y encuestas realizadas a los estudiantes. Esta propuesta también ganó el Premio a la Innovación y Mejores Prácticas en Docencia convocado por la Pontificia Universidad Católica del Perú, concurso en donde un jurado internacional de expertos especializados en innovación docente evaluó el desarrollo de competencias genéricas y habilidades colaborativas generadas, destacando la claridad, alineación curricular y el carácter sostenible y transferible de la innovación implementada.AbstractThe objective of this report is to showcase the effective techniques employed to teach building construction in a third-year civil engineering program at Pontifical Catholic University of Peru. This approach involves integrating virtual platforms and software for video conferences and laboratories, while utilizing tools like Building Information Modeling and Lean construction, among other systems. This balanced methodology serves as a successful model for imparting knowledge on building construction. Construction site visits were simulated by virtual tours created using scanner laser technology, photogrammetry, and BIM. The generated digital twins were placed on online platforms. Students interactively toured the construction project with input from professionals managing the project. Additionally, students developed layout plans using 3D and 4D BIM models. The course, however, instructed on generating and analyzing unit prices and conducting quantity surveys of activities through the BIM methodology with 5D software, resulting in the development of project budgets. Theeffectiveness of this methodology is evident in the high-quality papers, evaluations, and student surveys. This proposal also won the Award for Innovation and Best Practices in Teaching 2022 organized by the PontificiaUniversidad Catolica del Peru, where an international jury of experts in teaching innovation evaluated the development of generic competencies and collaborative skills generated in students, highlighting the clarity, curricular alignment and the sustainable and transferable nature of the innovation implemented.

“…In order to increase the transparency and quality of decision-making, Santa-Cruz et al [14] presented an approach based on the combination of building information modelling (BIM), information and communication technologies (ICTs), and multicriteria decision-making (MCDM) methods in determining priorities among seismic building renovation projects. The reason for including MCDM is reflected in the possibility of taking into account different criteria such as economic, social, environmental, and other criteria.…”

This paper aims to form a concept of infrastructure management based on a multicriteria approach to determining management priorities. As the complexity of infrastructure construction and maintenance management requires looking at this problem from different aspects, the proposed multicriteria approach in this paper is based on the application of a two-phase analytical hierarchy process (AHP) method and technique for order of preference by similarity to ideal solution (TOPSIS) method. Using the two-phase AHP method, the process of determining the relative weights of the criteria is improved with the aim of providing better management of stakeholders as one of the essential preconditions for the success of the entire management process. In this way, it is desired to simulate the decision-making process as realistically as possible, in which the opinions and interests of all stakeholders are respected, but the key decision-maker is responsible for the final decision. Furthermore, with the help of the TOPSIS method, a ranking list of maintenance management priorities is formed, based on which it is possible to distribute limited financial resources intended for annual maintenance more rationally. The stability of the TOPSIS results was confirmed by a sensitivity analysis when changing the relative weights of the criteria. The proposed allocation of financial resources represents the basis for a better design of the maintenance management plan of the analyzed infrastructure elements, thus completing the observed gap in the existing literature. The aim of the above is to improve the planning function and at the same time to improve the implementation, monitoring, and control management functions, which creates a more efficient management system that can preserve the value of the analyzed infrastructure elements and extend their lifetime.
