This has a positive impact on the public in terms of improving their well-being. This literature review attempts to compare the challenges encountered in implementation of PPP projects across the world, with a view to determining cross cutting challenges and recommendations for developing countries. A literature review was conducted for empirical studies focusing on construction projects. The studies are reviewed by analyzing the methodology used and conclusions made to identify the geographical study area, Public Private Partnership project financing model, emerging challenges and recommendation for future project management. The literature search was based on four keywords: construction projects, completion of construction projects, public private partnership, challenges in construction projects. Thus, a total of 11 empirical studies were identified for review in Europe, Asia and Africa. The review revealed that most risk factors affecting project completion can be categorized as human and organizational factors and unknown geotechnical conditions that were not known beforehand. Specifically, project owners’ interference was also attributable to delays with the delays having significant implications for project execution. Risks have great impact on the performance of construction projects because they affect their quality, time and cost. The general remedy to such potential risk factors is adoption of reliable prediction mechanisms which would estimate those factors using a probabilistic model that does not rely on expert judgments as they tend to be unreliable.展开更多

These issues require efficient risk management techniques. The success of construction companies running projects in international markets depends on how the risks arise from the host country conditions as well as the project specific risk factors. Successful management of risks requires identification of risks, construction of a risk model which can be used to assess the magnitude of risks, and implementation of response strategies so that an acceptable risk-return balance can be achieved. The project success usually depends on the combination of all risks, response strategies used to mitigate risks, and a company＇s ability to manage them. There exists a need to develop risk models containing the risks of doing business in international markets and factors that affect manageability of these risks. One of the market＇s critical challenges is scheduled management and the understanding and application of program management. This paper uses systematic risk identification, classification and analysis, and measurement and response methodologies to help international contractors quantify the risks of project development and accomplishment.展开更多

We collected relevant data on the number and distribution of civil airports, the construction of which had started or that had been assessed and approved. Based on a comparative analysis of the limits of ecological restoration in different ecologically vulnerable areas from the perspective of space, as well as an examination of ecological sensitivity factors in the ecosystems surrounding airport construction projects, suggestions concerning key ecological control techniques to be employed in airport construction projects in different ecologically vulnerable areas are put forward. The results showed that the airport construction projects recently approved by the Ministry of Water Resources and the Environmental Protection Agency are mainly distributed in the ecologically vulnerable areas of the Red Soil Hilly Area in southern China, the Karst Rocky Desertification Area in southwest China, the Agro-pastoral Ecotone in the southwestern mountain region, and the Desert-Oasis Connecting Belt in northwest China. The airport construction projects in the southwest mountain area, the hilly areas of southern China, and in the Qinghai-Tibetan Plateau are mainly based on the ecological technologies of slope protection, interception and drainage management, and vegetation restoration, respectively. In the arid and semi-arid areas, the ecological control technology employed in airport construction is mainly the rational utilization of water resources and reduction or mitigation of the effects of sandstorms. This study aims to serve as basis for soil and water conservation plans in airport construction projects and accelerate ecosystem restoration within the vicinity of airport construction sites.展开更多

It is critical how to realize collaborative work and information sharing among such participants. The information and communication technologies(ICTs) provides a technical guarantee for solving this problem. Existing research has been achieved the partial processes digitization of construction site, but certain problems still exist: 1)information perception of the construction site is passive.2) common collaboration and coordination problems in the construction industry have not been addressed. The emerging trends of ICTs have resulted in the integration of various computer technologies such as CPS, BIM, big data, and cloud computing into construction process,which would changes behavioral and management mode of construction sites. These new ICTs have been applied successfully in MCP, in particular, Hong Kong-ZhuhaiMacao Bridge project. A new management mode of construction sites is inspired by these case. In this paper, a new management mode of construction site for MCP has been proposed, namely, smart construction site. The ultimate goal of smart construction site is to accomplish safe, efficient and high-quality construction. This study put forward the conceptual framework for smart construction site, and have identified three key elements of smart construction site, including information support platform,collaboration work, and intelligent construction management. A case study on Hong Kong-Zhuhai-Macao Bridge project work as an evidence to support the practicability of the proposed mode. Significant contributions of this study is to propose a new management mode for MCP in construction industry, which would enrich the body of knowledge or the construction management community.Future research should be dedicated to further explore the potential of smart construction site in MCP management.展开更多

The results showed that the airport construction projects recently approved by the Ministry of Water Resources and the Environmental Protection Agency are mainly distributed in the ecologically vulnerable areas of the Red Soil Hilly Area in southern China, the Karst Rocky Desertification Area in southwest China, the Agro-pastoral Ecotone in the southwestern mountain region, and the Desert-Oasis Connecting Belt in northwest China. The airport construction projects in the southwest mountain area, the hilly areas of southern China, and in the Qinghai-Tibetan Plateau are mainly based on the ecological technologies of slope protection, interception and drainage management, and vegetation restoration, respectively. In the arid and semi-arid areas, the ecological control technology employed in airport construction is mainly the rational utilization of water resources and reduction or mitigation of the effects of sandstorms. This study aims to serve as basis for soil and water conservation plans in airport construction projects and accelerate ecosystem restoration within the vicinity of airport construction sites.

文摘The construction sites of mega construction projects(MCP) often have numerous participants with interfacing work within a highly complex system. It is critical how to realize collaborative work and information sharing among such participants. The information and communication technologies(ICTs) provides a technical guarantee for solving this problem. Existing research has been achieved the partial processes digitization of construction site, but certain problems still exist: 1)information perception of the construction site is passive.2) common collaboration and coordination problems in the construction industry have not been addressed. The emerging trends of ICTs have resulted in the integration of various computer technologies such as CPS, BIM, big data, and cloud computing into construction process,which would changes behavioral and management mode of construction sites. These new ICTs have been applied successfully in MCP, in particular, Hong Kong-ZhuhaiMacao Bridge project. A new management mode of construction sites is inspired by these case. In this paper, a new management mode of construction site for MCP has been proposed, namely, smart construction site. The ultimate goal of smart construction site is to accomplish safe, efficient and high-quality construction. This study put forward the conceptual framework for smart construction site, and have identified three key elements of smart construction site, including information support platform,collaboration work, and intelligent construction management. A case study on Hong Kong-Zhuhai-Macao Bridge project work as an evidence to support the practicability of the proposed mode. Significant contributions of this study is to propose a new management mode for MCP in construction industry, which would enrich the body of knowledge or the construction management community.Future research should be dedicated to further explore the potential of smart construction site in MCP management.
文摘In the highly overlapped contexts of urbanization and social transformation,and with the advent of the"Risk Society," the social issues,called "Not in My Back Yard(NIMBY)" conflicts,caused by the construction or operation of the NIMBY projects have become a serious problem in China.Hence,it is in urgent need to find out the influencing factors and discover the generation mechanism of the NIMBY conflicts.From the perspective of social conflict theory,the authors built a process model of the NIMBY conflicts on the basis of identifying stakeholders and analyzing their interest interaction.Thereafter,the authors conducted a questionnaire survey,followed by exploratory factor analysis(EFA) revealing the underlying influencing factors of the NIMBY conflicts.Finally,they performed the confirmatory analysis method of Structural Equation Modeling to test the preliminary research hypothesis of the model and its interaction path in AMOS 18.0,with the results showing that unequal exchange and consensus mobilization will contribute to the formation of common consciousness of the opposition party,the opposition party's common consciousness and action mobilization affects the generation of social conflicts.The process model reveals the generation mechanism of the NIMBY conflicts,and it facilitates further investigations in the governance of the NIMBY conflicts.
