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.

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.

This chapter presents a preliminary understanding of cross-cultural challenges and synergistic experiences of multicultural students engaged in Global Virtual Teams (GVTs). In this case study, we introduce the GVT structure as a novel learning platform which utilizes Computer Mediated Communication (CMC) tools as part of its virtual-based learning. We administer the case study with 30 students (n=30) in the United of Emirates (UAE) who engage in GVTs across the globe—encompassing 26 universities and 22 countries. Qualitative data is collected in the form of documents—reflective reports of the students’ experiential learning over a 10-week period. We content analyse the reports based on the thematic analysis with two distinctive categories—cultural challenges and cultural synergies based on the first seven weeks of the experiential learning process. In this study, we find that students experienced challenges such as managing technical difficulty, language barriers, deteriorating motivations, geographical distance, time differences, and non-committed and unresponsive attitude. However, students also experience synergies from the GVTs such as strong relationships and continued friendships, formation of emergent leadership, learned diverse managerial styles and competencies skills, varied use of varied CMC tools, and international exposure to diverse cultures without the need to travel abroad.
