HVAC Contractor's Growing Subcontractor Network
Summit Mechanical is an HVAC contractor with 60 field technicians, 18 subcontractors, and $18 million in revenue. It has grown 40% in two years by using subcontractors for peak commercial work. In the last 60 days, three near misses were reported: a van backing into a loading dock, a technician falling from the third rung of a ladder, and a refrigerant burn during a changeout. A new property-management contract requires Summit to name the owner as additional insured and waive subrogation for all subcontractors. The certificate file shows one subcontractor’s general liability policy expired six weeks ago. Five-year loss runs show five auto claims totaling $42,000, two general liability claims totaling $15,000, and no workers compensation claims, but four first-aid reports. The owner wants to “buy more insurance” and reuse a 2015 safety checklist. No one has reviewed the subcontractor agreement or mapped the workflow for the new contract.
1. Using at least four risk identification methods, explain what each would reveal about Summit’s exposures. Then classify at least three identified risks as hazard, operational, financial, or strategic.

Four identification methods and what they reveal:
- Loss-history review: auto backing claims, refrigerant burns, first-aid reports, and the absence of WC claims despite four first aids-possible underreporting.
- Physical/jobsite inspection: ladder setup, backing routes, refrigerant storage, PPE use, and housekeeping at commercial sites.
- Contract review: the new property-management contract’s additional-insured and waiver-of-subrogation requirements, indemnity wording, and subcontractor flow-down obligations.
- Flowchart/workflow analysis: how a subcontractor is onboarded, who verifies insurance, and where the new contract handoff can fail. Other methods: interviews, near-miss reports, financial statement analysis (subcontractor cost growth), and an updated checklist. Classification examples: backing and refrigerant exposure = hazard risks; reliance on subcontractors and rapid growth = operational/strategic risks; expired subcontractor certificate and contractual liability = financial/compliance risks. Identification asks what can happen; analysis later estimates frequency and severity. The 2015 checklist is a tool, not a program; it may miss subcontractor and contract exposures entirely.
2. The expired certificate is often treated as a compliance problem. Explain why it is also a risk identification failure and what the contractor should do before the next subcontractor starts work.

An expired certificate is a compliance symptom, but the underlying failure is that no one identified the subcontractor’s insurance status as a live exposure that changes daily. Risk identification should capture the subcontractor’s work scope, payroll, vehicles, safety history, and insurance requirements before mobilization, not after a certificate file audit. If the subcontractor is uninsured, Summit may bear liability for its acts, breach the owner’s contract, and lose additional-insured protection. Before the next subcontractor starts: prequalify in writing; obtain certificates directly from the broker or carrier; verify additional-insured and waiver-of-subrogation endorsements, not just limits; check expiration dates and auto-renew; require an indemnity/hold-harmless agreement; audit safety programs and vehicle records; and set a no-certificate-no-site-access rule. Assign an administrator to track expiration dates and require renewal certificates 30 days before expiration. The key judgement is that a certificate is evidence of insurance, not a control; the control is a prequalification process with authority to stop work.
