Complete guide to conducting construction site safety and quality audits. 12 steps from preparation to follow-up.
Before stepping on site, review the project's construction phase plan, recent inspection reports, and any outstanding corrective actions from previous audits. Your checklist should cover: site security, housekeeping, welfare facilities, PPE compliance, scaffold condition, excavation safety, fire safety, electrical safety, working at height controls, plant and equipment, COSHH compliance, and documentation currency.
Check that all required documentation is current and accessible on site: construction phase plan, RAMS for active work activities, permits to work, scaffold inspection records (within 7 days), crane thorough examination reports, COSHH assessments, fire risk assessment, and the site induction register.
Start with the site boundary. Check hoarding condition, security gates, public protection measures, signage (CDM notification board, emergency contact details, PPE requirements), and vehicle access/egress arrangements.
Verify that welfare facilities meet Schedule 2 of CDM 2015: heated rest area with seating and tables, clean drinking water, toilet facilities (1 per 7 workers), washing facilities with hot and warm water, changing and drying facilities, and first aid provisions.
Walk through each active work area systematically. Observe: are workers following their RAMS? Is PPE being worn correctly? Are exclusion zones properly established? Are work platforms in good condition? Are materials stored safely? Is housekeeping adequate?
Verify that all plant has current inspection records, operators hold appropriate CPCS/NPORS cards, daily pre-use checks are being completed, and any defective equipment is taken out of service and tagged.
Working at height is the leading cause of fatal injuries in UK construction. Check: edge protection on all platforms and openings, scaffold integrity and tag status, ladder use only where justified, harness anchor points for any unprotected edges, and netting or soft landing systems where appropriate.
Check fire extinguisher locations, inspection tags, and suitability for the risks present. Verify escape routes are clear and signed. Check hot works permits are in place where needed. Confirm that combustible materials are stored properly and waste is removed regularly.
A good audit includes worker engagement. Ask: Do you know the emergency procedure? Where is your nearest fire extinguisher? Have you been inducted on this site? Do you have access to the RAMS for your activity? Do you know how to report a near-miss? Workers' responses reveal the real safety culture.
Photograph every finding — both positive observations and deficiencies. GPS-stamp and time-stamp photographs where possible. Record findings in a structured format: observation, location, risk level, responsible person, and required action.
Rate each area on a consistent scale (typically RAG: Red/Amber/Green or a numerical score out of 10). This allows trend analysis over time and comparison between sites. Common scoring areas: housekeeping, PPE, documentation, welfare, working at height, fire safety, and environmental.
Compile your findings into a clear report within 24 hours of the audit. Include: executive summary, scoring overview, positive observations (recognise good practice), non-conformances with photographic evidence, corrective actions with deadlines and responsible persons, and comparison with previous audit scores.
