FAQs about business insurance for steel erection contractors
Review answers to frequently asked questions about steel erection insurance requirements and licensing.
Do I need a license or permit for my steel erection business?
State laws and local regulations typically require steel erectors to have a license and permit. To obtain them, you usually need to be bonded and insured.
Steel erectors must submit building designs and site preparation plans for approval, and comply with safety programs mandated by the Occupational Safety and Health Administration (OSHA).
Here are several examples of what you might need:
- Business license. To form a business, you'll need to get a business license and register with your local government.
- Contractor's license. In most states, you'll need a contractor's license to construct steel structures. You'll likely need to be a certain age, have a specific amount of experience, pass an exam, pay a fee, and show proof of liability coverage or a bond.
- Building permit. Steel erectors will need a permit from their local building and zoning department or state agency before they can begin a project.
- Additional permits. You might also need a permit for work that involves scaffolding, hazardous materials, equipment that releases pollutants, or excavation, all depending on your local regulations.
Even when it's not required, a license or certification in structural steel erection can help elevate your business above the competition when trying to get a contract or win a bid. The general contractor or project owner may also have their own requirements.
For example, you could get trained as a Certified Erector by the American Institute of Steel Construction (AISC) or a Steel Erection Specialist (SES) by the National Association of Safety Professionals (NASP).
Why do steel erection contractors need business interruption insurance?
Constructing steel frameworks requires a tremendous investment in time and money. These projects are also vulnerable to unexpected shutdowns from incidents such as a fire, storm, or vandalism at a construction site.
If your business is forced to halt operations temporarily due to a fire or other covered property claim, business interruption insurance, also called business income insurance, can cover your financial losses.
That might include:
- Lost profits
- Employee wages
- Rent or mortgage payments
- Leased equipment
- Temporary relocation
- Other day-to-day operating expenses
Because steel erectors have high operating costs and projects that can take a long time to complete, this policy provides essential coverage. You can usually add it to your commercial property insurance or business owner's policy.
What other types of insurance do steel erection contractors need?
Steel erectors often rely on other types of construction insurance as part of a comprehensive risk management strategy:
- Builder's risk insurance provides financial protection for a structure in progress and materials at a construction site in the event of theft or damage from a fire or storm.
- Commercial property insurance covers your office and its contents, including computers, furniture, and equipment stored at your business address. If you don't have an office, you can buy business personal property (BPP) coverage to protect the items that belong to your business instead.
- Commercial umbrella insurance activates to provide coverage when your underlying general liability insurance, commercial auto insurance, or employer's liability insurance policy reaches the limit on a claim.
Our agents can help you find the right insurance program for your unique risks. Get peace of mind with coverage that fits your business needs at an affordable price.
