ItemImproving design performance by alliance between contractors and designers in international hydropower EPC projects from the perspective of Chinese construction companies(MDPI AG, 2018-04-13)© 2018 by the authors. Extant literature lacks a systematic framework addressing the mechanisms of the alliance functional process and its impacts on management activities together with performance in delivering Engineering-procurement-construction (EPC) projects. This study quantitatively investigates the cause-effect relationships among these themes by building and validating a conceptual model of contractor-designer alliance in international hydropower EPC projects. With the support of data collected from an industry survey, the results reveal the key design problems, application of contractor-designer alliance, design management level and performance, which form a sound basis for design management emphasis in EPC activities, e.g., sufficiently considering sustainability of hydropower projects by incorporating environmental, social, and economic factors into designs. The path analysis indicates that the contractor-designer alliance can not only improve design performance by enhancing design management, but also directly promote design performance. This research has significant contributions to the body of knowledge by building interdisciplinary linkages between the areas of alliance, design management, and performance, theoretically demonstrating the mechanism of how interfirm cooperation functions to achieve superior design outcomes of hydropower EPC projects. Understanding these causal relationships will be crucial for contractors and designers to optimally allocate their complementary resources for seeking better design solutions in dealing with both technical issues and sustainability factors.

ItemQualitative Analysis of the Occupational Health and Safety Performance of Chinese International Construction Projects(MDPI AG, 2018-11-22)Chinese contractors undertaking international projects are frequently criticized for their poor Occupational Health and Safety (OHS) performance. It is noticed that people with different occupations may perceive OHS differently. From a qualitative perspective, this study investigates the perceived OHS performances of design managers and construction managers engaged in Chinese overseas construction projects, considering a range of subgroups classified by people’s overseas experience, project size, project industry, project location, and firm size. The analysis was based on an e-questionnaire survey that sampled responses from 52 design managers and 160 construction managers involved in 110 international projects, and face-to-face interviews with 26 managers. The findings indicate that the assessment variation of OHS performance between design managers and construction managers is not only related to their different mental ways, but also can be mediated by their in-progress communication and affected by project and organizational conditions. The varying OHS performance in projects with different sizes or from different regions also suggests that Chinese contractors should be more proactive in OHS management instead of passively responding to external requirements.
