Mega-engineering projects in the construction industry are generally carried out by public–private partnership models with the participation of different stakeholders. This paper aims to identify the effect of stakeholder-associated risks on the success of mega-engineering projects. Therefore, the risks were determined and then validated by focus discussions. Afterwards, an illustrative case study was presented to better understand the effects. Finally, a fuzzy analytical hierarchy process method was used to prioritize the identified risks. The prominent risks were found to include “improper partner selection,” “inadequate relationships with employer,” and “incompetent contractor selection.” Engineering managers need to work in close coordination with all members of the project. To better manage projects, engineering managers are expected to be familiar with the concepts of project risk management, because effective project risk management has a direct and positive effect on project management performance. Professionals in the field of engineering management can benefit greatly from the findings of this study by using it as a baseline for coordinating the relationships in multistakeholder organizational structures and analyzing stakeholder-associated risks throughout their projects.

Numerous studies have been conducted by researchers on the delay analysis topic, which is one of the primary areas of scientific study due to the effects of delays on time and cost in construction projects. Following fruitful contributions made by the researchers, it is believed to be extremely important to summarize the existing studies in terms of being a road map for future studies and practitioners. In this context, not only does this study aim to detect the most significant authors, sources, organizations and countries contributing to the improvement of delay domain in the construction industry concerning delay analyses worldwide but also to provide the researchers with extensive insights concerning the prominent research themes, trends and gaps in the literature. Hence, 168 documents related to delay analyses from 1982 to 11 February 2021 were detected through the Scopus Database and the Web of Science Database, and scientometric analyses were conducted via VOSviewer software. By evaluating the related research, two main research areas were detected in this field, namely; improving the delay analysis methods and resolving the disputes before they occur. This study is believed to make theoretical and practical contributions in that it examines the delay analysis topic in all aspects such as prominent institutions, countries, authors and sources, synthesizes the data and highlights possible research domains, gaps and trends concerning the delay analysis topic in construction industry.

Globalized competition and customer needs forced construction companies to measure their performance beyond the financial measures such as profitability, turnover, etc. As qualitative determinants were added to measurement systems, their investigation and evaluation became a major area of research. In this study, the impact of “resources and capabilities,” “strategic decisions,” “project management competencies,” and “strength of relationships with other parties” on “company performance” was investigated. A questionnaire survey was administered to 73 Turkish contractors and the results of the survey were analyzed using structural equation modeling. The findings indicate that, as expected, resources and capabilities and strategic decisions have an important and direct impact on company performance, whereas project management competencies and strength of relationships with other parties impact company performance only indirectly, through their impact on companies’ resources and capabilities and strategic de...

Changing of business conditions due to globalization, improved technology, transformed demands, needs of customers and etc. gives a rise to increase a competition in construction industry. In this context, in order to survive and sustain in the long term, construction companies should progress in the field of technology and innovation. Thus, innovation approaches such as information technology (IT) used in construction is one of the most essential in terms of competitiveness for the construction industry's success. Among IT tools such as designing and structural analyses programs (CAD, Revit, SAP2000), enterprise resource planning (ERP) and data management programs; the BIM technologies became a major shift for the construction industry in order to organize the reciprocal interdependencies between different stakeholders considering the increasing complexity of construction projects in design, bidding, construction and maintenance processes also with additional benefits on change control, decrease in repetition, energy efficiency, health and safety, risk and quality management. Taken into consideration of the worldwide rising importance of the BIM technologies, Turkish construction companies should tend towards the BIM use in order to increase their global competitiveness and to provide the sustainability of Turkish construction industry's performance. In this context, the main aim of this study is to diagnose Turkish construction industry to develop a clear understanding of the BIM adoption, to investigate challenges and benefits of the BIM applications in Turkish construction companies and to provide recommendations for the Turkish construction industry about the BIM implementation
