Architects and engineers don’t necessarily do the same type of job, but they are frequently tied together by insurance companies looking to provide professional liability coverage. Architects and engineers use the principles of math, science, and technology to create structures; at least, in general terms. 

According to Teach Engineering, the architect focuses more on how a building looks, whereas the engineer is more concerned with safety and meeting codes. A wide range of jobs fall under these two categories. Some of them are:

  • Electrical engineers
  • Structural engineers
  • Design architects
  • Production architects
  • Mechanical engineers
  • Land surveyors
  • Environmental consultants

Any of them can be sued for miscalculations, design flaws, or oversights. That’s where professional liability insurance (also called errors and omissions insurance or malpractice insurance – see how they are different here) comes in.

What is Professional Liability Insurance?

If a client is unhappy with some part of your work, professional liability insurance will protect you. It will cover:

  • Legal fees
  • Court costs
  • Settlements

Anything else, such as bodily harm or property damage, is covered by a different insurance policy, usually general liability insurance.

Errors and omissions insurance (or E&O and also called professional liability insurance: the two terms are interchangeable) provides protection against claims of negligence or mistakes that causes a client to suffer financial loss.

Why do Architects and Engineers Need Professional Liability Insurance?

Architects who design big money properties will undoubtedly be sued if expectations are not met. Princeton University filed a $10.7 million dollar lawsuit against lead designers for additional costs due to delays. (Archinect) And that’s just one lawsuit. 

Architects and engineers often serve corporate clients, who may be more inclined to sue to recoup their financial investment if things go wrong. And if you’ve worked as an architect or an engineer, you know that a lot can go wrong. Contractors can misinterpret renderings, resulting in delays. Someone orders incorrect materials and they can’t be returned. A structural engineer makes a bad recommendation. 

If you’re an independent contractor, just one lawsuit could bankrupt you. And you don’t have to be guilty of anything to be sued. Also, many of your clients may want to see proof that you have insurance.

What Affects How Much Architects and Engineers Pay for Professional Liability Insurance?

Why is there a discrepancy between architect and engineer insurance? Insurance companies have actuaries, the people who analyze all of the claims brought against a profession and analyze potential risks. Some engineering jobs carry higher risks because the potential lawsuits are bigger in the event a building collapses due to an engineering error. 

Below are the factors that affect how much architects and engineers pay for their professional liability insurance:

  • Amount of your deductible: Deductibles start at $1,000 and go up from there
  • Amount of your policy limit: The most common limit is $1,000,000 limit with a $1,000,000 aggregate, but up to $5 million is possible
  • Your field: There are many different types of engineers, and some carry more risk than others. 
  • Your claims history: The more claims you had in the past, the more your premiums are.
  • The types of materials you work with: Working with asbestos, lead, or other polluting materials will increase your premiums.
  • The types of engineers you are: There are forty different kinds of engineering degrees ( with engineers building everything from aerospace products to roller coasters. What you build will also affect rates. 
  • The types of things that you design: Architects can design anything from office buildings to stadiums. What type of building you design will affect rates to some degree, as will the size of the firm you work for, or the amount of revenue you earn if you work as a contractor. 

Last thoughts

Architects and engineers both work in the design field, although they have different roles. The architect is concerned with aesthetics, whereas the engineer is most concerned with safety and meeting enforced standards. Either one has the potential to be sued by an unhappy client, even if they didn’t do anything wrong. Professional liability insurance can help cover any errors or mistakes you made, or a client thinks you made.
