Which of the following services does professional liability insurance not typically cover for contractors?

Professional liability insurance is specifically designed to protect contractors and other professionals from claims of negligence, errors, or omissions during the course of providing their professional services. This type of insurance is particularly important for areas where professionals may give advice or provide services that can lead to financial losses for clients.

In the context of this question, the services that are typically covered by professional liability insurance include design services and project management, as these roles can lead to claims related to professional mistakes or inadequate services. General contracting, which can involve managing various aspects of construction projects, may also fall under protection from such insurance, though it can depend on the specifics of the policy.

Surveying, on the other hand, is usually considered a specialized professional service that may require a different type of insurance or additional coverage for liabilities specific to that field. It is often associated with structural assessments or land measurements, placing it outside the typical realm of contractor activities covered by standard professional liability insurance.

Therefore, the correct answer highlights the distinction between the services typically needing the protection of professional liability and those that don't fit as neatly within that category, such as surveying, which involves distinct risks and responsibilities that may require separate coverage.
