What is the ConSASS audit checklist?

The ConSASS audit checklist is a comprehensive tool used by MOM-approved auditors to systematically assess a construction worksite’s Safety & Health Management System (SHMS). It consists of 204 structured questions grouped into Bands I–III, covering key PDCA cycle stages:

  • Policy & Planning (Plan)
  • Support & Operation (Do)
  • Performance Evaluation (Check)
  • Improvement (Act)

  • Each question specifies the required audit method - Document Review, Interviews, or Physical Inspection - with auditors marking responses in “Yes/No/N/A” and providing comments. A minimum of 70% compliance in Bands I & II is required to progress to Band III.


    What are the ConSASS interview sheets?

    The Questionnaire for Interview of Personnel is intended to guide auditors in conducting informal conversations with various site personnel - such as managers, supervisors, workers, and contract staff, during the audit. The questions are derived from the main checklist and may be applicable only to certain groups (e.g., management-level staff). For audit items assessed using the Interview of Personnel (IP) method, at least 70% of interviewees must provide a positive response for credit to be awarded.


    What is the ConSASS scorecard?

    The ConSASS scorecard is a summary tool that tabulates audit results across the 20 SHMS elements evaluated. Auditors record the highest Band (I–III) achieved per element, input percentage scores, and fill in the necessary particulars including the company being audited, dates of audit, and the name of the lead auditor in the audit team with his/her signature.

    The completed scorecard visually represents the maturity profile of the site's SHMS, helping management identify areas for improvement.
