Identifying the driving factors of successful megaproject construction management:Findings from three Chinese cases

The construction of megaprojects has always resulted in extensive and long-term impacts on the society.However,the performance of megaproject management is poor,and improving it remains an urgent and necessary issue.Although many studies on megaproject success have been conducted,existing studies on the driving factors of successful megaproject construction are rather limited.Therefore,this study aims to systematically explore the key factors that can lead to successful megaproject construction management based on three cases:The Beijing-Shanghai High-Speed Railway,the Three Gorges Dam,and the Hong Kong-Zhuhai-Macao Bridge.Mixed research methods,such as literature review,case studies,and expert interviews,were used in this study.Consequently,11 driving factors,namely,government support,public support,accumulation and application of technology and experience,development and innovation of technology,innovation and application of management system,organizational mode and structure,top management support,project culture,megaproject citizenship behavior,corporate reputation,and fulfillment of social responsibilities,were identified and grouped into five categories,namely,project environment,construction capabilities,organization,positive culture and behavior,and requirements for sustainable development.The contributions of this study lie in two aspects.First,the driving factors of successful megaproject construction are identified to deepen the understanding of industrial practitioners,assist them in focusing on key factors,and aid them in effectively managing megaprojects.Second,researchers could use the identified driving factors in conducting further empirical studies and apply them in future projects to enhance their chances of success.

Small mammal community succession on the beach of Dongting Lake,China after the Three Gorges Project

Although the Three Gorges Project(TGP)may have affected the population structure and distribution of plant and animal communities,few studies have analyzed the effect of this project on small mammal communities.Therefore,the present paper compares the small mammal communities inhabiting the beaches of Dongting Lake using field investigations spanning a 20-year period,both before and after the TGP was implemented.Snap traps were used throughout the census.The results indicate that the TGP caused major changes to the structure of the small mammal community at a lake downstream of the dam.First,species abundance on the beaches in­creased after the project commenced.The striped field mouse(Apodemus agrarius)and the Norway rat(Rat­tus norvegicus),which rarely inhabited the beach before the TGP,became abundant(with marked population growth)once water was impounded by the Three Gorges Reservoir.Second,dominant species concentration in­dices exhibited a stepwise decline,indicating that the community structure changed from a single dominant spe­cies to a more diverse species mix after TGP implementation.Third,the regulation of water discharge release by the TGP might have caused an increase in the species diversity of the animal community on the beaches.A sig­nificant difference in diversity indices was obtained before and after the TGP operation.Similarity indices also indicate a gradual increase in species numbers.Hence,a long-term project should be established to monitor the population fluctuations of the Yangtze vole(Microtus fortis),the striped field mouse and the Norway rat to safe­guard against population outbreaks(similar to the Yangtze vole outbreak in 2007),which could cause crop dam­age to adjacent farmland,in addition to documenting the succession process of the small mammal community inhabiting the beaches of Dongting Lake.

Relationship between Project Consultants’ Performance and Project Success in the Rwandan Construction Industry

As discovered, today’s Rwandan construction industry is developing day by day, which plays a very important role in the country’s economic growth. In the construction industry, project consultants play a very significant role in providing services for such projects. The project consultants provide services from the beginning of the project to the completion of the project. Using project consultants is very useful for construction projects because it can ameliorate project efficiency and effectiveness. The main purpose of this paper is to investigate the relationship between project consultants’ performance and project success in the Rwandan construction industry. The data used in this study were obtained from primary and secondary sources. The secondary data was attained through an elaborated literature review of various books, articles, and papers related to this research to outlining and describing the chief ideas of this research title. The primary data was compiled through a questionnaire survey that was directed to 110 selected professionals in the construction projects in Rwanda to collect data from the site for statistical analysis of the research to test the hypothesis. However, a total of 90 usable responses were received within the scheduled period representing the response rate of 81.82%, which is likely to be representative and acceptable. Data collected from the questionnaire surveys were analyzed using the Statistical Package for Social Scientists (SPSS), excel spreadsheets, and Relative Importance Index (RII), which provide more merit presentations. The survey results show that even if there are many obstacles in the use of project consultants in the Rwandan construction industry such as lack of knowledge and practice in project consulting, lack of well-trained project consulting professionals, lack of training opportunities in project consulting, lack of knowledge and experience in addition to the senior management opposition, and lack of local project consulting guidelines and information;they are needed in the construction project to make it more successful through reducing and saving the overall project’s life cycle cost according to client’s wishes, keeping time of construction project, improving quality of the project products in the present and future, removing major variations that affect construction project with its attendant cost overrun, and advising on construction project process. Therefore, it is more important to remark that the good performance of the project consultants in any industry especially in the construction industry will contribute to the successful implementation of the project. From the results of the study, the performance of project consultants is closely related to the success of the construction industry in Rwanda. The project consultants’ leading skills and knowledge automatically guide the project to complete with accurate time, budget, and quality to make the project successful. In this paper, we will also consider the project success criteria;the role and responsibility of project consultants;the factors affecting the performance of project consultants;and the reasons that hinder the implementation of project consulting in the Rwandan construction industry.

An Inquiry into Success Factors for Post-disaster Housing Reconstruction Projects: A Case of Kerala, South India

The 2004 Indian Ocean Tsunami triggered significant destruction to housing and related infrastructures across various coastal districts of south India.Research shows that tsunami reconstruction projects in Kerala experienced different degrees of success and failure.On this background,this study explored factors that contributed to the successful implementation of tsunami housing projects in Kerala by(1)consolidating various critical success factors(CSFs)for post-disaster reconstruction(PDR)projects under‘‘project management success traits’’through content analysis of existing literature;(2)deriving a conceptual model that envisages project success in PDR contexts;and(3)assessing the impacts of those success traits on tsunami housing projects using confirmatory factor analysis.Necessary data were gathered through a survey of various stakeholders involved in tsunami reconstruction projects in Kerala using structured questionnaires.The research revealed that PDR project success is attributed to critical dimensions of project management such as institutional mechanisms,reconstruction strategies,project implementation,and stakeholder management.A conceptual model with the interplay of project success,success traits,as well as their CSFs identified the project management actions that must be monitored during reconstruction.Since the project management approach is widely recognized for PDR projects,these success traits hold huge potential for effective organization and management of housing reconstruction projects.The study also helped to identify project management traits that need improvements for the successful implementation of post-disaster housing projects in Kerala.Thus the research findings can serve as a foundational study for formulating project management strategies appropriate to PDR projects in Kerala.

Influence of Farmer Capacity Building in Institutional Linkages on Performance of Smallholder Irrigation Projects in Migori County, Kenya

The smallholder irrigation sector in Kenya is considered inadequately developed. The study views unawareness of critical success factors in the smallholder irrigation sector as contributing to poor performance of smallholder irrigation projects. Consequently, the study investigated influence of farmer capacity building in institutional linkages on performance of smallholder irrigation projects in Migori County, Kenya. The study embraced a pragmatic view of philosophy, and used cross sectional and correlation research design. The target population was 2815, and comprised farmers drawn from fifteen smallholder irrigation projects that receive water from River Kuja through Lower Kuja Project. The sample size was 341. The study used systematic random sampling procedure to draw the sample, and collected data using questionnaire. Data was analysed using descriptive and inferential statistics. The study established that farmer capacity building in institutional linkages has a significant influence on performance of smallholder irrigation projects (r = 0.803, R2 = 0.645, F (5, 331) = 120.254 and p < 0.000 < 0.05). Thus, the study recommends that Migori County Government come up with policies that link smallholder irrigation projects in Lower Kuja Project to institutions that provide land ploughing services, certified seeds and fertilisers, control of crop pests and diseases, transportation of farm produce and marketing of farm produce.

Design-Stage Prediction of Project Correctness or Incorrectness

The success of a software development project requires the early objective determination of the project’s correctness or incorrectness and the identification of the most effective solution for project management. However, few studies have been conducted on the reliable quantitative early judgment of correctness or incorrectness. In recent years, the collection and accumulation of actual attribute data from Japanese domestic software development projects have been conducted by the Software Engineering Centre of the Information-Technology Promotion Agency of Japan. In a previous article, we proposed a precise definition of project correctness or incorrectness and identified the important factors in successful projects;we also proposed a quantitative decision-making method for judging project correctness or incorrectness objectively and quantitatively on the basis of discriminant analysis using project completion attribute data. On the basis of the previous results, we propose a quantitative decision-making technique for the early judging of project correctness or incorrectness based on the attribute data of design stage as early stage of development.
