Authors:Paul James Pages: 1 - 26 Abstract: Risk and security management is an important aspect of construction activities, especially in countries where the level of security is challenging. This paper is focused on evaluating the impacts of risk/security measures resulting from stakeholder failures related to explosives mismanagement and security events, over an 18-month period, on a large, complex Dam project in a remote area in Pakistan. In July 2021, an incident occurred that had huge ramifications for the risk/security management of a large dam construction site. A qualitative methodology was utilised, where content analysis was conducted on project documentary evidence and where the research design targeted a closed population of 12 - Engineer supervisors/managers to explore their personal opinions. The outcomes indicated that the Employer, the Engineer, WB group and contractors engage in destructive managerial behaviour considered primarily to reduce project performance and create unsafe project situations that were systemically induced. Further, stakeholders are not managing explosives or the security situation underpinning poor project physical progress, leading to consistent project failure issues.

A lack of a centralized historical crash database impedes the efforts to perform large-scale studies to understand the causes of crashes. However, the information for most major crashes are normally shared on social media. Therefore, this study used social media posts to extract information related to head-on and run-off roadway (ROR) crashes that occurred between 2010 and 2020. A total of 661 crashes were collected, which included 409 head-on and 252 ROR crashes. Geographical Information System (GIS) applications and multinomial logit models were developed to understand the spatial distribution of crashes and the resulting severity. It was found that the spatial distribution of crashes differs significantly by type and severity. Head-on collisions were predominant in two eastern regions, while ROR collisions appeared to spread on a large scale across the entire country. The pattern of fatal collision includes one southern region in addition to the two Eastern regions. Conversely, the pattern of non-injury crashes shows predominance along the coastal area. The Multinomial model results showed that speeding was two times more likely to result in fatalities for ROR crashes. Crashes in rural areas were about two times more likely to be fatal, given that they were head-on collisions. Further, bus-involved crashes were less likely to result in injuries. The implications of these study findings to the practitioners are discussed. PubDate: 2022-12-26 DOI: 10.5296/jss.v7i1.20488 Issue No:Vol. 7, No. 1 (2022)
