Level of risk management knowledge among construction project managers in Sri Lanka
(researchgate.net, 2022-06-24) Welikala, D. H. N; Jayasena, H. S; Perera, B. K. C
Risk management often becomes a significant concern among the construction professionals especially due to the complex nature of the industry. Though it is a popular subject in project management discipline, it was observed that authentic application of the principles of risk management at times is arguable in practice. As a Project Manager who is a key role player in a project, it is vital to have a solid knowledge on risk management and its related arena. Evidence was found of limited risk management knowledge among construction professionals. Therefore, a study was conducted to find the status of risk management knowledge among the construction Project Managers in Sri Lanka. A mixed method approach was followed by a comprehensive literature review on elements of body of knowledge of risk management and later a questionnaire survey to contextualise the status of the knowledge gap of Project Managers in real. According to the findings of the study, it could be concluded that Sri Lankan Project Managers are not fully confident on their risk management knowledge. It was primarily likely to be due to the limited learning in the subject area when pursuing higher studies. The study also identifies the options to device appropriate strategies to improve risk management knowledge among the Construction Project Managers in Sri Lanka.

REGULARITIES AND PATTERNS OF CONSTRUCTION COSTS UPON POLITICAL EVENTS
(SLIIT, 2022-02-11) Perera, B. K. C; Jayasena, H. S
Though the market prices change before and after political events were often speculated, if such changes could be systematically accounted for in construction cost forecasting was unknown. This study aimed to bridge this knowledge gap by identifying the regularities and patterns of the construction costs upon political events. A decade of period was selected in which the scope of the study started in 2010. Time series analysis was used along with regression analysis, assuming a linear relationship between construction costs and time. After a comprehensive literature review, CIDA construction cost indices were chosen as the most appropriate cost representation for the local context, and these were taken as the dependent variables. All indices were plotted in diagrams and long-term trends were observed, then indices were carried for further analysis of cycles. Major political events were collected through a document survey and the findings were plotted on the time series analysis output. It was noticed that in 2013 indices were changed mostly, where three provincial elections were held, and some more pattern changes had occurred close to the local government elections which took place in 2011 and 2018. The study concluded that there is neither pattern nor regularity in construction costs upon political events where it cannot be systematically incorporated into construction cost forecasting. However, the findings did not deny the impact of political events on construction costs, and novel areas were found where further explorations are required.
