Insurance & Bonding: Risk Transfer Demystified
Construction is the business of managing risk. Insurance transfers that risk from your balance sheet to a carrier's.
The Big Three Policies
Every legitimate contractor needs three primary instruments of risk transfer. Operating without them is negligent and often illegal.
1. Commercial General Liability (CGL)
CGL protects your business from financial loss should you be liable for property damage or personal and advertising injury caused by your services, business operations or your employees. It does not cover your own work (e.g., if you build a roof wrong, CGL won't pay to replace the roof, but it will pay for the water damage to the house below it).
- Typical Limits: $1M per occurrence / $2M aggregate.
- Rating Basis: Usually based on gross revenue or payroll.
- Crucial Endorsement: Additional Insured (allows you to name a GC or owner on your policy).
2. Workers' Compensation
Statutory coverage required by almost all states if you have employees. It covers medical costs and a portion of lost wages for employees injured on the job, regardless of who was at fault.
- Rating Basis: Payroll × Class Code Rate (e.g., Roofers pay much higher rates than Trim Carpenters).
- Experience Modifier (X-Mod): A multiplier based on your claim history. An X-Mod of 1.0 is average. An X-Mod of 1.25 means you pay 25% more than average. Safety programs directly impact your management costs.
3. Surety Bonds
A bond is not insurance. It is a credit instrument. It involves three parties: the Principal (you), the Obligee (the client or state), and the Surety (the backer). If you fail to perform, the Surety pays the Obligee, and then the Surety comes after you for the money.
- License Bond: Required by the state to maintain your contractor license.
- Bid Bond: Guarantees you will honor your bid if awarded.
- Performance & Payment Bond: Guarantees the work will be completed and subcontractors/suppliers will be paid.
Common Mistakes
Not Checking Subcontractor Certificates
If you hire a subcontractor who doesn't have Workers Comp, and their employee gets hurt, your Workers Comp policy will have to pay the claim. Always collect Certificates of Insurance (COIs) before they step on site.
Action Over Exclusions
Many cheap CGL policies include "Action Over" exclusions. This means if a sub's employee gets hurt, collects workers comp, and then sues you (the GC) for an unsafe site, your CGL policy won't defend you. Read the exclusions.
Frequently Asked Questions
What is Builders Risk Insurance?
It's property insurance for a building under construction. It covers damage from fire, wind, theft, and vandalism to the structure itself and materials on site.
How do I lower my premiums?
Implement a strict safety program to lower your X-Mod for Workers Comp. For CGL, ensure accurate classification of your work (don't let them rate you as a framer if you only do finish work).
