Environmentally conscious construction has become a subject of research during the last decades. Even though construction literature involves plenty of studies that emphasize the importance of environmental impact during the construction phase, most of the previous studies failed to combine environmental analysis with other project performance criteria in construction. To achieve environmentally conscious construction and successfully manage a complex construction environment, multiple project objectives and their relationships need to be considered. In this study, the authors propose a framework on the basis of the concept of control accounts to determine optimal construction operations when project time, cost, and environment impact (TCEI) are considered as project objectives during project planning. The framework also supports decision-making by using sensitivity analysis. Life cycle assessment is applied to the evaluation of environmental impact in terms of global warming potential (GWP).

The construction industry has a considerable share in overall resource and energy consumption. Consequently, decision-makers try to achieve environmentally conscious construction by integrating environmental objectives into the selection of construction elements. Due to the complexity of construction projects, it is a known challenge to provide an effective mechanism to select the most feasible construction methods. Thus, it is crucial to learn the interdependency between various resource alternatives, such as material and equipment type, under various project conditions like unavailability of resources. An analytic network process (ANP) was used in this study to construct a decision model for selecting the most feasible construction method. Data collected via interviews with highway construction experts were used to model the dependency between decision parameters, such as project conditions and resource performance indicators. The proposed ANP model output the relative importance weights of decision parameters so that they can be used to identify environmentally conscious construction methods. The proposed mechanism is a valuable asset for construction decision-makers especially when their ability to select construction methods is limited by project constraints. Although the model was tested in a highway project in this paper, it can be further extended to benefit building construction and sustainable decision-making problems.

The learning era of construction management (CM) has been enriched with the introduction of cyberspace, where the traditional learning process was exchanged with a smart learning environment. Despite the benefits of technical improvements, cyberspace has brought pedagogical challenges in motivating and assessing students. The main problem has become finding and choosing the most effective technology for cyber educators, who are challenged with technological improvements and lack of a comprehensive review and analysis on previous cyberlearning applications. This gap in literature has been the motive to prepare a review on a selection of cyberlearning tools and methods in CM education. The purpose of this paper is to present a comprehensive literature review on the history of computer tools and how the key ways of using technology have been used to promote CM learning in cyberspace. A critical literature review was combined with means and methods of teaching in previous studies to assess a variety of cyberlearning applications such as virtual reality technologies, simulation and gaming and Cyber-Physical Systems. This study is valuable for CM education educators and research to learn about the applications and trends in CM cyberlearning, as well as gaps in the knowledge to fill.

Over the past decade, the construction industry has undergone significant change due to technological advancements. Among these, Building Information Modeling (BIM) has been one of the pioneer technologies to impact this transformation. Projects using BIM reported increased productivity with expedited work of project stakeholders while maximizing their collaboration. While BIM has achieved remarkable success in developed countries, its adoption in developing countries remains limited. Studies showed that the acceptance of BIM technology is still very low in some countries. This study examines the status of BIM adoption including exploring the barriers as well as the factors that contribute to overcoming these barriers in adopting BIM in developing countries. BIM enablers in construction projects from the perspective of public clients were examined via a systematic review performed through the literature to identify these factors. Interviews were conducted with public clients to examine these factors. The average severity of each factor was ranked by clients. Notably, the study reveals that unfavorable economic conditions, high costs, and unclear project benefits as the significant barriers to BIM adoption. Clear advantages of BIM were reported as the ease of use, high analysis ability, positive attitude of the company, and demand/satisfaction of the clients.
