Building Information Modeling (BIM) has been widely adopted in the building sector. However, it is still an emerging topic in road infrastructure projects despite its enormous potential to solve ongoing issues. While there have been several recent studies on BIM implementation in road projects, there is a lack of research analyzing the actual BIM Uses in road projects as reported in academic and technical documents. Considering this gap, this paper presents a systematic review of BIM Uses and complementary technologies to BIM in road infrastructure projects. The research method consisted of a systematic review composed of five stages: (1) question formulation, (2) searching of relevant documents, (3) document selection, (4) evidence collection, analysis, and synthesis, and (5) results report. A total of 384 documents were collected, from which 134 documents reporting BIM Uses on roads were analyzed. This study has two main contributions. First, 39 BIM Uses were identified, which are classified into nine categories: road design, traffic analysis, soil aspects, road safety, environmental issues, other engineering analysis, construction planning and analysis, cost analysis, and construction monitoring and control. Second, a set of 26 technologies complementary to BIM adoption in roads were identified, among the most prevalent of which are geographic information systems (GISs) and laser scanning. The results serve as a basis for researchers to learn about the status and propose future developments on BIM adoption in road infrastructure.

Los retrasos y sobrecostos en proyectos de construcción son objeto de constante preocupación por parte de los desarrolladores de proyectos, ya que incluso pueden afectar la viabilidad de estos. Por esto, es necesario estudiar las causas, especialmente en Colombia donde las causas generadoras de este tipo de desviaciones no han sido analizadas a profundidad. Esta investigación, realizó inicialmente una revisión de la literatura para identificar causas generadoras de desviaciones en tiempos y costos a nivel mundial. Posteriormente se realizó una encuesta dirigida a profesionales dedicados al desarrollo de proyectos de construcción en Colombia, para poder conocer en su concepto los factores significativos en la generación de desviaciones en tiempos y costos. Finalmente se ejecutó un análisis de significancia basado en los factores influyentes, estableciendo las correlaciones entre estos y aspectos como magnitud, tipo de proyecto, tamaño de las empresas, entre otros, implementando herramientas estadísticas y computacionales. El estudio arrojó la inadecuada planeación y falta de integración entre profesionales como uno de los factores más influyentes en la fluctuación de costos y tiempos en el país.

Teaching production systems and Lean tools is a challenge for educators in the construction area, which is highlighted by the difficulty of emulating in the classroom the scenarios that industry professionals will face. Hence, implementing pedagogical games has a high potential to improve construction education processes. However, gaps are observed in the proposal of pedagogical games applicable to teaching construction systems based on Lean tools. Considering this gap, this paper proposes a game of paper planes to support the teaching of production systems in construction based on the Lean tools Continuous Improvement Cells and 5S. The research method consisted of applying the Design Science Research (DSR) method to develop, evaluate, and improve the game proposal. Thus, the game was assumed as an artifact subject to a development and improvement process to solve an identified problem. The proposed game consists of three main rounds: (1) production system design, (2) Continuous Improvement Cells implementation, and (3) 5S implementation. The main theoretical and practical contribution is the proposal of a pedagogical game to support the teaching of construction production systems based on Lean tools, evaluating students’ knowledge by applying surveys before and after the game and assessing performance indicators. The application of the game to a group of undergraduate and graduate students showed a broad positive impact on the assimilation of the principles of construction production systems based on Lean tools.

Rural roads play an indispensable role in economic and social well-being, especially in developing countries, contributing to achieving the Sustainable Development Goals. For this reason, it is necessary to plan these projects properly to guarantee their success. In this line, the objective of this research is to identify significant variables generating overruns in time and cost using empirical data of 535 rural road projects in Colombia from 2015 to 2018. Bivariate analysis, with statistical tools like Spearman’s Rho and Kruskal–Wallis, allowed identifying that higher values of variables like budget and project intensity are related to higher deviations in cost and time. Additionally, it was found that projects with shorter durations are reporting higher time overruns. The worst performers are projects executed in the year that council mayors start their terms, those developed in municipalities with more resources, and those awarded using a competitive bidding process. Multivariate analysis, through Random Forest, assessed the effect of considering all variables interacting simultaneously and ranking them in order of importance. The results demonstrated a relationship between cost and time performance, and that numerical variables are more significant than the categorical ones. This study contributes to a better understanding of the causes of delays and cost overruns on rural roads, providing useful insight for researchers and industry practitioners.
