Abstract:
Objective To solve the problems in selecting analog objects for occupational hazard pre-evaluation in construction projects by establishing an analogy database of construction projects to prioritize analog objects and improve analog deduction reliability.
Methods Based on the accumulation of occupational hazard evaluation data, an analog database was established and used to identify analog objects meeting selected requirements. Statistical balance test on objects selecting was performed.
Results The prioritized objects selection was explained by an example. A balance test was applied to the most appropriate analogy objects which were identified by a query filter in two projects using the established database (P > 0.05).
Conclusion Prioritized selection using analog database querying in combination with statistical principle can improve the quality of pre-evaluation of occupational hazards in construction projects.
