Why Contractor Management Matters
In most commercial buildings, 60-80% of maintenance and project work is performed by contractors. Contractors cause a disproportionate share of building incidents because they are unfamiliar with site-specific hazards, procedures, and emergency arrangements. Effective contractor management is not bureaucracy but a direct safety control.
Applicable Standards
- ISO 45001 — Occupational Health and Safety Management
- ISO 41001 — Facility Management Systems
- OSHA General Duty Clause — Employer responsibilities for contractor safety
- CDM Regulations (UK model) — Construction Design and Management
Contractor Lifecycle
| Phase | Actions | Documents |
|---|---|---|
| 1. Pre-qualification | Verify company registration, insurance, safety record, relevant experience, trade licences | Company profile, insurance certificates, safety policy, reference projects |
| 2. Scope and contract | Define scope clearly, include safety requirements, specify permit requirements, agree SLA/KPIs | Contract, scope of work, method statement, risk assessment (RAMS) |
| 3. Site induction | Building-specific hazards, emergency procedures, restricted areas, permit requirements, PPE rules | Induction record (signed), ID badge, access card |
| 4. Permit to work | Issue permits for high-risk activities (hot work, electrical, confined space, height, roof) | Completed permit form, RAMS, toolbox talk record |
| 5. Supervision | Monitor work quality and safety compliance, verify permit conditions maintained | Inspection checklist, photo records |
| 6. Completion | Verify work complete to spec, site restored, permits closed, as-built info provided | Completion certificate, handover documents, updated drawings |
| 7. Review | Assess performance against SLA/KPIs, record issues, update approved contractor list | Performance review record, incident reports if any |
Site Induction Checklist
Every contractor must receive site induction before starting work. Induction must cover:
- Site-specific hazards (asbestos locations, live services, overhead power lines)
- Emergency procedures (fire alarm, evacuation route, assembly point, first aid)
- Permit to work requirements (which activities need permits, who issues them)
- Restricted areas (electrical rooms, plant rooms, roof access, server rooms)
- PPE requirements (minimum and task-specific)
- Working hours and access arrangements
- Waste management and housekeeping rules
- Accident and incident reporting procedure
- Hot work and smoking restrictions
- Parking and delivery arrangements
Insurance Requirements
| Insurance Type | Minimum Cover | Purpose |
|---|---|---|
| Public liability | BDT 5-10 crore (or USD 1-2M) | Damage to third parties or property |
| Employer liability | BDT 5 crore (or USD 1M) | Injury to contractor employees |
| Professional indemnity | BDT 2-5 crore (for design work) | Errors in design or professional advice |
| All-risks/CAR | Contract value | Damage during construction/installation |
Performance KPIs
| KPI | Target | Red Flag |
|---|---|---|
| Response time (emergency) | Within SLA (typically 2-4 hours) | Repeated SLA breaches |
| First-time fix rate | Above 80% | Below 60% |
| Safety incidents | Zero | Any RIDDOR-reportable incident |
| Permit compliance | 100% | Any work without valid permit |
| Defect-free handover | Above 90% | Below 70% |
| Documentation delivery | Within 5 working days | Consistently late |
Common Failures
- No induction — contractor arrives and starts work without knowing emergency procedures or site hazards.
- Scope creep without reassessment — contractor starts additional work outside the original risk assessment.
- Expired insurance — insurance certificates not checked at renewal. An incident with lapsed insurance exposes the building owner.
- Sub-contracting without approval — main contractor brings unknown sub-contractors who bypass induction.
- Poor housekeeping — contractor leaves materials, waste, and trip hazards in occupied areas.

Insights & Guidance
- 60-80% of building maintenance is done by contractors. They cause a disproportionate share of incidents due to unfamiliarity with site hazards.
- 7-phase contractor lifecycle: pre-qualification, scope/contract, induction, permits, supervision, completion, review.
- Every contractor must complete site induction covering hazards, emergencies, permits, PPE, and restricted areas before starting work.
- Insurance verification is not optional. Check certificates at contract award AND renewal dates.
- Track KPIs: response time, first-time fix rate, safety incidents, permit compliance, defect-free handover.
Contractors who are not properly managed create safety risks, quality failures, and liability exposure. A contractor incident on your site is your incident from a legal and insurance perspective.
- No induction — contractor does not know emergency procedures or site hazards.
- Expired insurance — an incident with lapsed insurance exposes the building owner to full liability.
- Unapproved sub-contracting — unknown workers bypass all controls.
- Approved contractor list with pre-qualification records
- Signed induction records for all contractors
- Current insurance certificates on file
- Completed permit to work forms
- Are contractors wearing ID badges?
- Are permits displayed at work locations?
- Is the work area properly cordoned and signed?
- Do you have an approved contractor list?
- What does your contractor induction cover?
- How do you verify contractor insurance is current?
