Construction Project Safety Performance Management Using Analytic Network Process (ANP) as a Multicriteria...

Area of Science:

• Construction Management
• Risk Assessment
• Occupational Safety

Background:

• The construction industry faces significant risks due to intense labor, machinery, and overlapping activities, leading to accidents and fatalities.
• Accidents incur substantial costs and delays, negatively impacting all project stakeholders.
• Effective hazard identification and impact quantification are vital for construction safety planning, yet risks are complex and interconnected.

Purpose of the Study:

• To address the literature gap in understanding hazard interconnections and occurrence frequencies in construction.
• To identify and prioritize construction risks by considering their interrelationships and frequency.
• To develop a novel integrated methodology for construction risk assessment.

Main Methods:

• Utilized a survey distributed to 106 construction professionals to gather data on hazard interconnections and frequencies.
• Employed the frequency-adjusted importance index to quantify risk impact.
• Integrated the Analytical Networking Process (ANP) tool for risk prioritization, using importance index results for pairwise comparisons.

Main Results:

• Identified and prioritized key risks within the construction sector based on their interconnections and frequency of occurrence.
• The integrated approach provides a comprehensive understanding of risk dynamics.
• The study successfully combined the frequency-adjusted importance index and ANP for the first time in risk assessment literature.

Conclusions:

• The developed methodology offers a robust framework for prioritizing construction risks, considering their complex interdependencies.
• Findings provide valuable insights for industry professionals to enhance building safety and mitigate potential delays and costs.
• This research contributes a novel, integrated approach to construction risk management and safety analysis.
