Social Network Analysis (SNA) is a significant tool for analyzing networks in complex project management that examines the actors' interdependence in iterative and interactive social structures. It can also be used for non-social structure analysis. The potential of SNA could be extended significantly if its application to complex project management could be clarified. The objectives of the present review are threefold: (1) to clarify the interpretation of SNA metrics; (2) to identify its applications to complex project management knowledge areas; and (3) to reveal its uses in the non-social structures of complex networks. The authors conducted a qualitative systematic review based on 65 peerreviewed publications to identify 38 SNA metrics and concepts in nine complex project management knowledge areas. The findings show that SNA is a useful tool for application to the analysis of non-human resource networks and can be used for strategic planning and the improvement of project transmission efficiency and interdisciplinary interactions. The authors also delineated the future studies and the potential applications of SNA to provide new insights into advancing the use of SNA for analyzing and mitigating complex project management issues.

Safety monitoring is a critical component of safety management. However, asymmetric safety information and inefficient communication between various stakeholders currently limit the effectiveness of safety monitoring in the construction industry. The aim of this study is to develop a holistic and collaborative information integration framework for safety monitoring that collects, analyzes, and disseminates safety information. The proposed framework provides an interconnecting platform for stakeholder communication consisting of five layers for safety monitoring: preparation layer, monitoring layer, integration layer, reporting layer, and intervention layer. To evaluate the proposed framework, a prototype system was developed and tested as a case study for building projects in Qingdao, China. The results indicate that the proposed framework and prototype were embraced by the stakeholders in the city and contributed to an improved collaborative working environment for safety inspection and monitoring in construction projects.
