Many of the large number of underground works constructed or under construction in recent years are in unfavorable terrains facing unusual situations and construction conditions. This is the case of the subject under study in this paper: a tunnel excavated in evaporitic rocks that experienced significant karstification problems very quickly over time. As a result of this situation, the causes that may underlie this rapid karstification are investigated and a novel methodology is presented in civil engineering where the use of saturation indices for the different mineral specimens present has been crucial. The drainage of the rock massif of El Regajal (Madrid-Toledo, Spain, in the Madrid-Valencia high-speed train line) was studied and permitted the in-situ study of the hydrogeochemical evolution of water flow in the Miocene evaporitic materials of the Tajo Basin as a full-scale testing laboratory, that are conforms as a whole, a single aquifer. The work provides a novel methodology based on the calculation of activities through the hydrogeochemical study of water samples in different piezometers, estimating the saturation index of different saline materials and the dissolution capacity of the brine, which is surprisingly very high despite the high electrical conductivity. The circulating brine appears unsaturated with respect to thenardite, mirabilite, epsomite, glauberite, and halite. The alteration of the underground flow and the consequent renewal of the water of the aquifer by the infiltration water of rain and irrigation is the cause of the hydrogeochemical imbalance and the modification of the characteristics of the massif. These modifications include very important loss of material by dissolution, altering the resistance of the terrain and the increase of the porosity. Simultaneously, different expansive and recrystallization processes that decrease the porosity of the massif were identified in the present work. The hydrogeochemical study allows the evolution of these phenomena to be followed over time, and this, in turn, may facilitate the implementation of preventive works in civil engineering.

Purpose – Rework is an endemic problem in construction projects and has been identified as being a significant factor contributing cost and schedule overruns. Causal ascription is necessary to obtain knowledge about the underlying nature of rework so that appropriate prevention mechanisms can be put in place. The paper aims to discuss these issues. Design/methodology/approach – Using a supervised questionnaire survey and case-study interviews, data from 112 building and engineering projects about the sources and causes of rework in projects were obtained. A multivariate exploration was conducted to examine the underlying relationships between rework variables. Findings – The analysis revealed that there was a significant difference between rework causes for building and civil engineering projects. The set of associations explored in the analyses will be useful to develop a generic causal model to examine the quantitative impact of rework on project performance so that appropriate prevention strategies can be identified and developed. Research limitations/implications – The limitations include: small data set (112 projects), which include 75 from building and 37 from civil engineering projects. Practical implications – Meaningful insights into the rework occurrences in construction projects will pave pathways for rational mitigation and effective management measures. Originality/value – To date there has been limited empirical research that has sought to determine the causal ascription of rework, particularly in Hong Kong.

Abstract As part of the trend toward internationalization of higher education, governments and universities have introduced policies to encourage the expansion of English-medium instruction (EMI). However, top-down policies do not necessarily translate to teaching and learning practices. This article provides a case study examining the implementation of undergraduate EMI engineering programs at a state university in Turkey to explore the gaps that exist between national- and institutional-level EMI policies and classroom-level practices. Data were collected through policy documents, classroom observations, semi-structured interviews with teachers, and focus group discussions with students. The findings suggest that the implementation of EMI varies across classrooms, even within the same university department. Despite policies that envision one-language-at-a-time instruction, the EMI lecturers in this study varied in terms of language preference and teaching practice in their EMI lectures. Implications are discussed with respect to policy planning, teacher training, and the expansion of EMI across university contexts.

The flipped classroom, as an active learning model, has given remarkable results in several areas in the university teaching; however, its execution is still able to improve. This research shows the implementation and improvement of the flipped classroom model in the course of Pavements. It evaluates their influence on the students’ final grades and their learning experience. Three groups of students participated in this study, who enrolled in the course of Pavements in the Civil Engineering. Group A took the course with the traditional model, while Group B took it with a flipped classroom, and Group C experienced it with a reinforced flipped model. Groups did the course the subject in 2017, 2018 and 2019, respectively. Results show that even though with the flipped classroom models, the finals grades did not increase compared to the scores of the traditional model; however, it improved their learning experience. The students were more satisfied with the method; they even asked for fewer modifications than they did in the traditional model. This research shows that adding little academic things to the course, it would greatly influence their students' opinion.

El Lean Project Delivery System (LPDS) es un sistema que implementa principios y herramientas Lean en todo el ciclo de vida de un proyecto de construcción. El LPDS es adaptativo pues es flexible para especificar las entradas y salidas de los procesos y tiene la libertad de elegir herramientas, técnicas y tecnologías acorde a las últimas tendencias. El propósito principal de este artículo es presentar un marco de generación de valor a través de la adaptación del LPDS al proceso de revisión de un plan de estudios. Este trabajo adapta el modelo del LPDS al proyecto de elaboración o actualización de un plan de estudios de la especialidad de ingeniería civil, incorporando BIM, realidad virtual y fotogrametría a lo largo de las asignaturas del área de gestión de la construcción. Se incluyen herramientas blandas y competencias tecnológicas que potencian la empleabilidad del egresado. Como estudio de caso se presenta la aplicación del modelo en la Pontificia Universidad Católica del Perú.ABSTRACTLean Project Delivery System (LPDS) is a system that implements Lean principles and tools throughout the life cycle of a construction project. The LPDS is adaptive because it's flexible enough to specify the inputs and outputs of each process and allows the freedom to choose tools, techniques and technologies according to the latest trends. The main purpose of this paper is to present a value-generation framework through the adaptation of the LPDS to the Undergraduate Degree Plan process. This work adapts the LPDS model to the current project, elaboration or updating of the civil engineering curriculum, incorporating BIM, virtual reality and photogrammetry in the construction management area subjects. Soft tools and technological skills are included, and as such, enhancing the employability of the undergraduate.

Global Classroom

A new learning opportunity among civil engineering students is learning about urbanization in cities, which combines the sub-disciplines of civil engineering in a seamlessly interdisciplinary manner.  One of the greatest benefits of learning about a global phenomenon such as urbanization is introducing the opportunities to offer examples of the technological, cultural and social diversity surrounding the evolution of urban design, technologies and sustainable strategies from global cities. The ability to have a globally diverse classroom to bring in these perspectives and create a learning experience that captures this information sharing and exchange can be created through course design, learning activities, and assessments, hence the “global classroom.”  The authors present a case study of the global classroom for the online course “Sustainable Cities: Adding an African Perspective” and share their perspective on learner-driven formats that support the global classroom, which hinges upon students’ own interest and commitment to an online learning format.
