“…Toole (2002) conducted a survey that has shown the lack of uniform agreement on site safety responsibilities among design engineers, general contractors, and subcontractors. Thekdi and Lambert (2014) demonstrated that consensus on risk mitigation is difficult to achieve among stakeholders within infrastructure projects due to discrepancies in perspective, expertise, and interests.…”

Safety management in construction is an integral effort and its success requires inputs from all stakeholders across design and construction phases. Effective risk mitigation relies on the concordance of all stakeholders’ risk perceptions. Many researchers have noticed the discordance of risk perceptions among critical stakeholders in safe construction work, however few have provided quantifiable evidence describing them. In an effort to fill this perception gap, this research performs an experiment that investigates stakeholder perceptions of risk in construction. Data analysis confirms the existence of such discordance, and indicates a trend in risk likelihood estimation. With risk perceptions from low to high, the stakeholders are architects, contractors/safety professionals, and engineers. Including prior studies, results also suggest that designers have improved their knowledge in building construction safety, but compared to builders they present more difficultly in reaching a consensus of perception. Findings of this research are intended to be used by risk management and decision makers to reassess stakeholders’ varying judgments when considering injury prevention and hazard assessment.

“…Applications of risk and uncertainty analysis in systems engineering have had considerable interest in recent years (e.g., Thekdi and Lambert 2014;Xu et al 2014;Hamilton et al 2013;Lambert et al 2013a, b;Karvetski and Lambert 2012;Ayyub et al 2012). In a system-level formulation, an image or a model of an object that emphasizes some important and critical properties is defined.…”

“…While the definition of time to develop and contributing factors has been modeled in earlier work using several alternative perspectives [26,27], this paper has focused on a single perspective elicited from experts. The data for each influential factor was processed to define levels for each factor value.…”
