In recent years, the construction industry has adopted methodologies such as Lean Construction and Building Information Modelling (BIM). Various studies have explored the benefits of integrating these tools to optimize projects. Construction companies, responsible for executing projects that involve multiple stages, often delegate specialized tasks to subcontractors. However, the involvement of multiple subcontractors with varying levels of experience can complicate communication, leading to issues such as rework. Therefore, this study focuses on improving the effectiveness of daily task communication during the finishing stage of multifamily housing projects through a Lean-BIM integration model. The methodology used in this study includes: (A) recording and analyzing information through surveys and interviews, (B) identifying the conventional process, (C) developing a new process, and (D) implementing the proposed process in the third evaluated project. The results show that the proposed approach significantly enhances the communication of daily tasks, enabling more efficient interactions.

The current drinking water system in Cupiche is inefficient and lacks adequate maintenance, which generates a poor and scarce service. The research starts from this critical need and proposes a new system suitable to improve the situation. The methodology adopted is a mixed approach, combining qualitative and quantitative tools. The Epanet software was key in this research, since it allowed modeling and simulating the water distribution network, analyzing critical variables such as flow, pressure at the nodes and estimated demand to project the functionality of the system.

La estabilización de suelos mediante materiales naturales ha cobrado importancia en la ingeniería civil, destacándose el uso de residuos agroindustriales como la cáscara de coco, un recurso sostenible con múltiples beneficios. Este artículo realiza una revisión de la literatura actual sobre los efectos de la cáscara de coco y cemento en la estabilización de suelos, enfocándose en sus propiedades químicas y físicas, así como en su aplicación en suelos arcillosos y de baja capacidad portante. Los estudios analizados indican que el uso de cáscara de coco, en sus formas triturada o como polvo de carbón, mejora significativamente la resistencia al corte, la capacidad de carga (medida a través de ensayos CBR) y la resistencia a la deformación. Asimismo, la adición de este residuo reduce la expansión del suelo en condiciones de humedad, lo cual es crucial para la durabilidad de las infraestructuras viales en regiones con suelos problemáticos. Se discuten además los porcentajes óptimos de incorporación y los métodos de ensayo empleados en las investigaciones revisadas, resaltando la utilidad de esta alternativa como un método ecológico y económicamente viable para la estabilización de subrasantes. La revisión concluye que el empleo de la cáscara de coco en proyectos de estabilización de suelos es una estrategia eficaz para mejorar las propiedades mecánicas del suelo, reducir el impacto ambiental y fomentar la reutilización de residuos orgánicos.

In Peru, "self-construction" represents a constant risk due to its numerous deficiencies, one of them being the lack of curing for concrete structures. This situation leads to serious structural risks. Therefore, the objective of this research was to experimentally determine the influence of the lack of curing on the compression resistance using concrete specimens, this was evidenced through compression resistance tests carried out at 3, 7, 14 and 28 days, obtaining resistance results of 281.32 kg/cm², 300.82 kg/cm², 324.58 kg/cm² and 376.44 kg/cm² respectively in the cured specimens while for the uncured specimens they were 249.15 kg/cm², 263.34 kg/cm², 289.22 kg/cm² and 312.91 kg/cm² respectively, showing a loss of resistance of 16.9% after 28 days. Concluding that the compressive strength of concrete is significantly higher for those that are in a 100% cured condition compared to those that have not been cured. This is why it is important not to overlook this process, in order to guarantee the obtaining of quality concrete, thus contributing to the advancement of knowledge and best practices in the construction industry.

The prevalence of roads in poor condition violates safety and affects the comfort of drivers and pedestrians on their daily journeys. Therefore, in this research article, the influencing factors are determined during the self-repair process of the flexible pavement in Jiron Arguedas using mechanomutable asphalt material, in the Villa Maria del Triunfo district, compared to traditional asphalt mixture designs. It presents a quantitative approach, obtaining the results in numerical values ​​through experimental tests with the study of its behavior at scale. From one of the results obtained, it can be highlighted that the interior heat conservation capacity of the samples is 0.28%. increased by 99.07% and that of 0.90% by 39.81% compared to that of 0% steel wool, of the three samples the one that presented a better level of self-repair is the one that had a average percentage of steel wool, allowing the tar to maintain its thermoplastic property for longer, filling its cracks, and when it is no longer exposed to heat it solidifies again, completing its self-repair cycle. It was concluded that the mechanomutable asphalt material can contribute to the reduction of road maintenance periods required by traditional flexible pavements through its self-healing property. This contribution to the development of self-healing pavements will not only improve its durability, but will also promote a safer and more efficient road environment for all users.

This study seeks to address the need for innovation in the improvement of subgrades, highlighting the importance of the bearing capacity of the soil in the construction of infrastructure. This is why a detailed investigation is presented on the use of metallic spark as an innovative material to improve soil properties. The results obtained demonstrate a significant improvement in the CBR index (California Bearning Ratio), confirming the viability and effectiveness of this method.

The conclusions highlight the potential of metallic spark to strengthen foundations, providing a solid foundation to develop more resilient infrastructure. The recommendations suggest expanding the research to various contexts and optimizing the application of the metallic spark. This study contributes to the advancement of geotechnical engineering, offering new perspectives for sustainable soil improvement in construction projects.
