“…Construction projects that are characterized by elements of high uncertainty and interdependent units can be referred to as complex projects (Sridarran, Keraminiyage and Herszon, 2017). They further opined that a project referred to as large size (that is, spanning over several years, or involving billions of dollars) does not necessarily imply that it is complex -it may just be resource intensive.…”

The characteristics of a project that makes it hard to understand, predict, and manage its general behavior despite the availability of required information relating to the project dynamics is referred to as project complexity. A good knowledge of project complexity at the construction phase of a project, as well as a well thought out plan to manage complexity will determine how proficiently construction projects are planned, managed, and executed in an environmentally friendly manner. The level of complexity of construction projects to a large extent determines the performance or otherwise of the projects with regards to achieving specific environmental standards. At construction sites, the effects of adopting green site practices on environmental performance is largely dependent on the level of complexity inherent in the project’s construction processes. This study investigates the moderating effects of project complexity on the relationship between various green construction site practices and environmental performance of construction projects. A survey was conducted on class A contractors in Nigeria and 168 usable responses were received. The data were analyzed using the partial least squares structural equation modelling technique. The results show that project complexity moderates the relationship between waste management and environmental performance, and the relationship between materials management and environmental performance. But project complexity does not moderate the relationship between energy management and environmental performance. The study provides important theoretical and practical information for construction managers in understanding the dynamics involved in managing of projects with different degrees of complexity, while adopting certain green site practices with the aim of delivering projects with high degree of environmental performance.

Evaluation of complexity is of considerable importance for project managers in mega projects. Project managers faced with complexities that have not worked so far and are new to their kind. While as for the complexity of project, there is still a lack of complete understanding of the complexity concept among practitioners in the industry as well as in project management body of knowledge. In this regard, the traditional project management principles and practices are not capable of controlling emerging complexities in mega projects. Undoubtedly one of the key factors for success in mega projects is knowledge of project managers about overall complexities and contributing factors on complexities. As the main approach of this paper is overview the factors of complexity in mega projects, a systematic literature review analysis on complexity features in mega projects achieved by examining over one hundred and fifty published research papers during the period of 2012-2019. As a result of this exploration, the research highlighted three (3) dimensions (Environmental, Technological, and Organizational) and over seventy-three factors of complexity in mega projects from the extent literature. The research findings help scholars and practitioners in the project management field developing the perception of complexities in managing mega projects effectively.

“…e inherent complexities and uncertainties of construction projects are due to the involvement of many parties, as well as political, economic, and social conditions under which the projects operate [4]. Complicatedness and uncertainties may have negative effects on the project with respect to cost, time, quality, safety, and sustainability [5,6].…”

Construction projects are typically conducted in a complex and dynamic environment in which the accumulation of many interrelated factors causes high uncertainty. Many factors may have negative effects on construction projects and thus cause project cost overruns. The aim of this study is to identify significant cost-influencing factors for sustainable development in construction. Considering the effects of economic and environmental factors on project cost is indeed a challenging task due to the shortage of appropriate methodology. This study examines the relationships between cost-influencing factors and construction project cost by using a structural equation model based on the generalized maximum entropy (GME) and Bayesian estimation methods. The advantages of GME and Bayesian methods are discussed, and results obtained from the statistical analysis are provided for illustration. The results can enhance cost performance through the identification and evaluation of the cost-influencing factors. The improved project performance is considered as an important step to transit into a sustainable development in construction. The sustainable development may greatly affect the emission reduction target of the industry.
