Review of the application of social network analysis (SNA) in construction project management research

Safety leading indicators for construction sites: A machine learning approach

Business Process Management (BPM) includes methods, techniques, and tools to support the design, enactment, management, and analysis of operational business processes. It can be considered as an extension of classical Workflow Management (WFM) systems and approaches. Although the practical relevance of BPM is undisputed, a clear definition of BPM and related acronyms such as BAM, BPA, and STP are missing. Moreover, a clear scientific foundation is missing. In this paper, we try to demystify the acronyms in this domain, describe the state-of-the-art technology, and argue that BPM could benefit from formal methods/languages (cf. Petri nets, process algebras, etc.).

Business Process Management: A Survey

Does working from home on a given day complicate or rather facilitate combining work and home roles that day, why and for whom? To answer these questions, we examined how a teleworking day affects daily work-to-home conflict and daily home-to-work conflict. Based on boundary theory, we expected these relationships to be mediated by daily role transitions and moderated by employees’ preferences to protect their home(/work) domain from work(/home) interruptions. Hypotheses were tested through multilevel moderated mediation modeling using diary data collected during 14 consecutive workdays with 81 employees (N = 678 data points). In line with our expectations, employees were found to make more work-to-home transitions (i.e. interruptions of work activities to deal with home demands during work hours) on teleworking days, which was related to lower work-to-home conflict but higher home-to-work conflict on these days. They also made more home-to-work transitions (i.e. interruptions of home activities to deal with work demands after hours) on teleworking days, which was related to more work-to-home conflict on these days. The latter effect was stronger for employees with a home protection preference. There was no moderating impact of work protection preference. Overall, employees experienced less work-to-home conflict but more home-to-work conflict on teleworking days compared to non-teleworking days.

Adopting recycled aggregates as sustainable construction materials: A review of the scientific literature

Leading or lagging? Temporal analysis of safety indicators on a large infrastructure construction project

Decisions made during the design stage of construction projects can impact work health and safety (WHS). Design decisions arise as the result of social interactions and information exchanges between project actors. Interactions can be studied using social-network analysis (SNA). The patterns of social interaction that underpinned key design decisions with the potential to impact construction WHS were investigated in an Australian case-study project. SNA was applied longitudinally to capture network information for 42 sequential design decisions. Changes in network density were examined over time, and networks were compared before and after a contractor was engaged. In-depth interviews explored differences in design and WHS outcomes. The results revealed changing social networks over the study period. Furthermore, improvement in WHS-related design outcomes was observed as participants with relevant construction knowledge joined the social networks and moved to prominent positions. It is argued that understanding how social networks change and play out to produce project outcomes (e.g., WHS) can help project leadership teams to develop communication networks that are more likely to support effective decision making and performance.

Understanding the dynamics of construction decision making and the impact on work health and safety

The position of the constructor in communication networks, including those before the commencement of construction, is likely related to the quality of work health and safety (WHS) outcomes realized. In order to examine the extent of this relationship, 23 cases were drawn from 10 participating construction projects in Australia and New Zealand. Social network analysis was used to mathematically and graphically model information exchanges in 13 of these cases. For each case, the quality of WHS risk control outcomes was measured. This measurement was based on an established ‘hierarchy of control’ in which risk controls are classified in descending order of effectiveness from the elimination of a hazard (the most effective) to the reliance on personal protective equipment (the least effective). Social network metrics were calculated reflecting: (1) the ratio of actual links among parties in the project network relative to the maximum number of links possible (network density); and (2) the extent to which the...
