Developing a safety audit checklist for in-operation administrative buildings.

Background: The structure of buildings is in degradation over time, monitoring their safety status and providing timely warnings is crucial. Therefore, an efficient visual inspection of the building's safety has intrinsic value to give early warnings to owners and managers.

Objective: This study aimed to provide an audit tool for evaluation of the administrative in-operation buildings' safety status.

Methods: Factors affecting the administrative buildings' safety status was determined based on the National Building Regulations of Iran (NBRI) and other studies. Checklist items and their guidelines were prepared. Face validity (quantitative and qualitative), Content Validity Ratio (CVR), and Content Validity Index (CVI) were calculated for the checklist. The Intra-class Correlation Coefficient (ICC) used for inter-rater reliability and Cronbach's α was used to evaluate internal consistency of the checklist.

Results: Forty-seven items related to in-operation building safety were extracted from literature review. Based on the results of the psychometric analysis, 5 items were removed and 42 items remained. The values of different psychometric indices for the other items indicated their acceptable validity (α= 0.82, ICC≥0.75).

Conclusion: The designed checklist had a good level of validity and reliability for inspecting architectural, technical services, and managerial safety aspects of administrative in-operation buildings. Stakeholders can use it for quick and comprehensive assessment of building safety. Use of this checklist are expected to give early warnings about the safety of buildings to the stakeholders.
