5.4 Subcontractor Safety File Verification and Onboarding
Key Takeaways
Construction Regulation 7(1)(c)(i)–(x) requires the principal contractor to issue the specification, check safety pricing, verify competence and COIDA good standing, appoint in writing, approve plans, audit and stop unsafe work.
A contractor that appoints another contractor takes on the principal contractor's CR 7(1)(b)–(g) duties towards it (CR 7(3)), and must be reasonably satisfied of its competence (CR 7(2)(c)).
Onboarding checks include a valid COIDA letter of good standing, a signed Section 37(2) agreement, Annexure 3 certificates from an occupational health practitioner, and proof of operator competence.
CR 7(1)(c)(vii) requires site audits and document verification of each contractor at agreed intervals, but at least once every 30 days.
CR 7(1)(c)(viii) requires the principal contractor to stop any contractor whose work departs from the specification and plan or threatens anyone's health and safety.
5.4 Subcontractor Safety File Verification and Onboarding
Cascading Statutory Duties under Construction Regulation 7
Modern construction projects rely heavily on specialized trade contractors—such as structural steel erectors, piling specialists, HVAC technicians, electrical contractors, and earthmoving teams. In South African occupational health and safety law, the term "contractor" denotes any employer who performs construction work, while "principal contractor" denotes the primary employer appointed in writing by the Client under CR 5(1)(k).
A critical legal principle governs this hierarchy: the Principal Contractor cannot sub-contract away its statutory safety oversight. Under Construction Regulation 7, the legislature created a cascading governance structure. Most duties the client has towards the principal contractor under CR 5 are mirrored downstream in CR 7(1)(c), and a contractor that appoints another contractor takes on the principal contractor's duties in CR 7(1)(b)–(g) towards it (CR 7(3)).
Core Principal Contractor Duties toward Subcontractors
- Provision of Specification (CR 7(1)(c)(i)): Give contractors tendering for work the relevant sections of the client's health and safety specification;
- Tender Financial Verification (CR 7(1)(c)(ii)): Ensure that potential contractors submitting tenders have made sufficient provision for health and safety measures;
- Competency and Resource Assessment (CR 7(1)(c)(iii)): Appoint no contractor unless reasonably satisfied that it has the necessary competencies and resources to perform the work safely;
- Compensation Fund Verification (CR 7(1)(c)(iv)): Ensure before work starts that every contractor is registered and in good standing with the Compensation Fund or a licensed compensation insurer such as FEM;
- Written Appointment (CR 7(1)(c)(v)): Appoint each contractor in writing for its part of the project;
- H&S Plan Approval (CR 7(1)(c)(x)): Discuss and negotiate the contractor's health and safety plan and then finally approve it for implementation (CR 7(2)(a) requires the contractor to provide it before performing any construction work);
- Audits (CR 7(1)(c)(vi)–(vii)): Take reasonable steps to ensure each contractor's plan is implemented, with periodic site audits and document verification at agreed intervals but at least once every 30 days (the 7-day report rule in CR 5(1)(p) applies to client audits; many specifications apply it to principal contractor audits too);
- Stop-Work Authority (CR 7(1)(c)(viii)): Stop any contractor executing work that is not in accordance with the specification and plan or that threatens the health and safety of persons;
- Contractor Register (CR 7(1)(f)): Keep in the file an updated list of all contractors on site accountable to the principal contractor, the agreements between the parties, and the type of work being done.
Step-by-Step Subcontractor Onboarding Protocol
To satisfy these statutory obligations and prevent unsafe subcontractors from infiltrating the site, the Principal Contractor's Construction Health and Safety Manager (CHSM) must implement a formal four-phase onboarding gateway:
Phase 1: Procurement & Tender Vetting (Issue Spec & Verify Safety Budget)
↓
Phase 2: Pre-Mobilization Safety File Audit (Technical Verification)
↓
Phase 3: Formal Plan Approval & Induction Clearance (Written Sign-Off)
↓
Phase 4: Site Access, DSTI Integration & Monthly Auditing (Continuous Oversight)
Phase 1: Procurement and Tender Vetting
Before commercial contracts are finalized, the Principal Contractor's procurement team, in conjunction with the CHSM, must issue the project-specific H&S specification to tendering subcontractors. Subcontractors must submit an itemized safety budget detailing allocations for PPE, medical fitness exams, equipment certifications, and safety supervision. Bids with zero-rated safety line items fail CR 7(1)(c)(ii) and should not be accepted.
Phase 2: Pre-Mobilization Safety File Audit
At least two weeks prior to scheduled mobilization, the subcontractor must submit their physical or digital site safety file. The CHSM conducts a comprehensive audit against a standardized verification checklist, interrogating legal appointments, risk assessments, safe work procedures, and employee competency files.
Phase 3: Formal Plan Approval and Induction Clearance
Once all non-conformances are resolved, the Principal Contractor executes a formal Subcontractor Health and Safety Plan Approval Letter under CR 7(1)(c)(x). Subcontractor supervisory personnel and artisans are scheduled for mandatory site-specific safety induction under CR 7(5). Biometric or physical access cards are issued only after induction completion.
Phase 4: Operational Oversight and Monthly Auditing
On site, subcontractor teams must participate in daily pre-task briefings (DSTIs) and adhere to the Principal Contractor's Permit-to-Work systems. The CHSM conducts formal audits at least every 30 days under CR 7(1)(c)(vii). If serious non-conformances or imminent hazards are detected, the CHSM or Construction Manager stops the work under CR 7(1)(c)(viii).
Mandatory Onboarding Verification Documents
During Phase 2 auditing, the CHSM must verify four non-negotiable statutory pillars:
1. COIDA / FEM Letter of Good Standing
Every subcontractor employer must hold a valid, unexpired Letter of Good Standing issued by the Compensation Commissioner (under Act 130 of 1993) or the Federated Employers Mutual Assurance Company (FEM). The CHSM must verify:
- That the trading name on the letter matches the contracting legal entity precisely;
- That the nature of business classification covers the intended construction activity (e.g., civil earthworks vs electrical installation);
- That the expiry date extends beyond the anticipated contract period (or diarize monthly tracking for renewal dates);
- Warning: An invoice or proof of electronic payment to the Department of Employment and Labour does not constitute a valid Letter of Good Standing. Without an official letter bearing an authentic verification reference, the subcontractor cannot start work (CR 7(1)(c)(iv)).
2. Section 37(2) Mandatary Agreement
Section 37(2) of the OHS Act applies the Section 37(1) presumption to mandataries: an employer is presumed to have committed its contractor's offences unless the parties have agreed in writing on the arrangements and procedures to ensure the contractor's compliance. The agreement should therefore record those arrangements:
- The agreement must explicitly stipulate that the subcontractor (as mandatary) warrants that all work will be performed in full compliance with the OHS Act and Construction Regulations;
- Critical Legal Boundary: While a Section 37(2) agreement protects the Principal Contractor from vicarious criminal liability for the direct unilateral negligence of the subcontractor, it does not exempt the Principal Contractor from its affirmative duties under Construction Regulation 7. A Principal Contractor who signs a Section 37(2) agreement but fails to inspect the subcontractor's file, fails to approve their plan, or fails to ensure audits at least every 30 days remains liable for its own breaches of CR 7(1)(c)(vi)–(x).
3. Medical Certificates of Fitness (CR 7(8))
Every subcontractor employee must hold an individual Annexure 3 medical certificate of fitness issued by an occupational health practitioner (CR 7(8)). The CHSM must verify:
- The certificate specifically certifies fitness for the intended physical trade;
- Where the subcontractor executes working at heights (scaffolding, structural steel, roofing) or confined space work, the certificate must explicitly state "Fit for Working at Heights" or "Fit for Confined Spaces";
- Expiry dates must be tracked. CR 7(8) sets no fixed validity period; follow the practitioner's expiry date, which is commonly 12 months.
4. Competency Verification and Equipment Certification
Subcontractors must provide verified proof of competency for all specialized trades and plant items:
- Plant Operators: Proof of competency and written authorisation for construction vehicles and mobile plant (CR 23(1)(d)), and lifting machine operators trained for the specific machine (Driven Machinery Regulation 18(11)), from accredited training providers;
- Scaffolding Personnel: SANS 10085 competency certificates for Scaffold Erectors, Scaffold Inspectors, and Scaffold Supervisors;
- Lifting Tackle: Examination records at intervals not exceeding 3 months for slings, chain blocks and wire ropes (Driven Machinery Regulation 18(10)(e));
- Hand and Power Tools: Daily pre-use inspection records for electrical machinery (CR 24(e)) and the site's periodic portable tool inspection and tagging records.

A structural steel erection subcontractor arrives on a major civil site to commence assembly. During file verification, the Principal Contractor's CHS Manager discovers that the subcontractor's COIDA Letter of Good Standing expired two weeks prior. The subcontractor's director presents an electronic banking receipt proving that an assessment fee was transferred to the Compensation Commissioner three days ago, claiming this entitles them to immediate site access. Under Construction Regulation 7(1)(h), how must the Principal Contractor act?
The Principal Contractor may allow the work to proceed for 14 days while the Department of Employment and Labour processes the banking payment.
Refuse access and work until a valid letter of good standing from the Fund or FEM is produced.
The Principal Contractor must pay a penalty fee on behalf of the subcontractor and deduct the amount from their initial progress certificate.
Allow it if the workers sign indemnity waivers.
A principal contractor signs a comprehensive Section 37(2) mandatary agreement with an electrical installation subcontractor. Two months into the project, the electrical subcontractor fails to implement lock-out/tag-out (LOTO) procedures, resulting in an electrician suffering severe arc-flash burns. An investigation reveals that the Principal Contractor never reviewed the subcontractor's safety file, never approved their health and safety plan, and conducted no audits under CR 7(1)(c)(vii). How does the signed Section 37(2) agreement affect the Principal Contractor's statutory liability?
It shifts all liability onto the injured electrician under Section 14.
The Section 37(2) agreement provides an absolute, impenetrable legal shield that exonerates the Principal Contractor from all criminal and civil charges.
It does not protect the principal contractor, whose CR 7 duties to approve plans, verify files and audit remain.
The Section 37(2) agreement is rendered legally void because electrical installations fall under the Electrical Installation Regulations rather than the Construction Regulations.
During an audit of a bulk earthworks subcontractor under Construction Regulation 7(1)(c)(vii), the principal contractor's safety manager finds a 20-tonne tracked excavator being operated by a labourer who has no proof of competency, no written authorisation and no medical certificate of fitness. Under Construction Regulation 7(1)(c)(viii), CR 23(1)(d) and Section 8 of the OHS Act, what must the principal contractor do immediately?
The Principal Contractor must assume direct operational ownership of the excavator and assign an internal site foreman to operate it without amending the contract.
Fine the labourer R5,000 on the spot and take his driver's licence.
The Principal Contractor must allow the operator to finish the day's trenching shift and table the non-conformance at the next monthly safety committee meeting.
Stop the excavator, remove the unauthorised operator, and allow no restart until a competent, authorised operator is provided.
