Linear infrastructure projects, including roads, tunnels, and railroads, are vital for the socioeconomic advancement of regions and nations. Given their large scale, these projects require significant resources, leading to substantial environmental impacts and demanding the collaboration of professionals from multiple disciplines. In this context, it is essential to adopt strategies that favor digitalization to enhance the sustainability of such projects by automating the analysis of various alternatives. Despite the proliferation of studies in this area, there needs to be more research synthesizing the main trends in digitalization and sustainability in linear projects. Given this knowledge gap, this study focuses on identifying and analyzing the main trends in digitalization and sustainability in the context of linear infrastructure projects. To this end, a comprehensive bibliometric analysis of a selected set of papers has been carried out. The research method follows five main steps: (1) scope definition, (2) selection of bibliometric analysis techniques, (3) data collection, (4) bibliometric analysis execution, and (5) evidence analysis and synthesis. An analysis of 419 documents was done, applying performance analysis and scientific mapping techniques. The results reveal that trends in digitalization and sustainability in linear projects can be categorized into five main clusters: road construction, road administration, life cycle analysis, digitalization of linear infrastructure, and sustainable development, leading this line of research towards computer-aided design technologies such as BIM, GIS, and computer vision to study sustainable development throughout the whole life cycle analysis of linear infrastructure projects.

During the 16th and 17th centuries, Latin American cities adopted earthen construction techniques from European colonizers. As a result, rammed earth (RE) buildings now occupy an important place in Latin America’s cultural heritage. However, earthquakes around the world have shown that unreinforced earthen constructions are highly vulnerable. For several years, researchers in northern South America have been proposing a technique that consists of installing confining steel plates (or wooden elements) on both sides of the RE walls to form a grid. This system has shown excellent performance in controlling seismic damage and increasing strength and ductility capacity. Although researchers have tested full-scale one- and two-story earthen walls under pseudo-static loading in the laboratory, and one- and two-story earthen walls at 1:1 and 1:2 scales on uniaxial and biaxial shaking tables, the behavior of a complete reinforced module (one- or two-story) on a shaking table has never been assessed. The present study presents the results of shaking table tests performed on two-story RE modules at 1:4 scale. The experimental data indicate that the retrofit system with confining steel plates was effective in reducing the seismic damage of earthen constructions. In addition, the comparison of the results of the 1:4 scale tests with the 1:2 and 1:1 scale tests previously conducted by the researchers shows that the acceleration levels of the equivalent prototypes are in the same order of magnitude for the three scales.

The integration of digital technologies in managing technical and design information is transforming architecture, engineering, and construction (AEC) processes within educational institutions. Despite this, construction education lacks practical, interactive learning tools, and there is insufficient collaboration between academia and the construction industry. To address these challenges, the CAMPUS 2.0 project at Pontificia Universidad Javeriana developed a web-based platform that integrates building information modeling (BIM) and gamification elements. This platform improves project coordination, facilitates interdisciplinary learning, and enhances the management of technical and design information for campus buildings. CAMPUS 2.0 also promotes collaboration and active user engagement, filling a critical gap in the practical tools in construction education. This study assesses the usability of CAMPUS 2.0 among 235 students, teachers, and staff members, demonstrating a positive impact on the university community. The findings provide insights into how digital tools can improve project management, interdisciplinary collaboration, and knowledge sharing within educational settings, offering broader implications for other institutions.

The present study presents the results of shaking table tests performed on two-story RE modules at 1:4 scale. The experimental data indicate that the retrofit system with confining steel strips was effective in reducing the seismic damage of earthen constructions. In addition, the comparison of the results of the 1:4 scale tests with the 1:2 and 1:1 scale tests previously conducted by the researchers, shows that the acceleration levels of the equivalent prototypes are in the same order of magnitude for the three scales.
