On the one hand, these projects are charaterised with the need for high design knowledge and technical skills; competent human resources and managerial capabilities as well as excessive cost investment. Conversely, developing countries experience shortage of many of these requirements, which obstruct the development of (MCPs). This paper aims to identify, validate, and classify the challenges of delivering (MCPs) in developing countries. Towards achieving this aim, two approaches were employed, namely literature review and case studies, to accomplish four objectives.
Challenges of mega construction projects in developing countries• Reviewing the nature and characteristics of developing countries and (MCPs); identifying the challenges of delivering (MCPs) in developing countries and establishing the need for (MCPs) in developing countries.• Validating the challenges identified from Litearture review through collecting and analysing 36 case studies of (MCPs) in developeding countries. Case studies confirmed many of the identified challenges and added new insights that were not covered in current literature.• Classifying the identified clalenges into four categories: engineering challenges, human development challenges, managerial and political challenges and sustainability challenges.• Outlining research conclusions and recommendations useful for delivering successful (MCPs) in developing countries.
• Firstly, building a comprehensive background of the research topic through covering: the nature of construction industry, its stages and players, identifying the factors of project failure and their impacts.
Open public green spaces (OPGSs), such as parks and gardens, sports facilities and green corridors, play a significant role towards providing environmental, social, and economic functions and benefits to communities. Environmentally, they are air and water purification, wind and noise filtering, microclimate stabilization. In addition, they reduce stress, rejuvenate people, and provide peacefulness. Socially, OPGSs encourage the use of outdoor spaces, increase social integration and interaction among neighbors. Finally, its economic services include air purification by trees that reduces costs of pollution prevention; promotion of city as a tourist destination; and increase of property values. However, literature review and case studies showed that OPGSs are not fully satisfying their intended functions and benefits to communities. As an approach for increasing the sustainability of OPGSs, this paper aims to investigate the causes of inefficient use of OPGSs in Egypt. A research methodology based on literature review, is designed to build a comprehensive background of the research topic through reviewing the definition of OPGSs, functions and benefits of them as well as identifying the causes of inefficient use of OPGSs.The importance of this research emerges from the need to improve the environment, social and economic role of OPGSs and increase its sustainability. In addition, it raises the awareness of designers and proposes a criterion and guidelines to be considered during the design of OPGSs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
