AIA B101 requires which insurance type for covering errors and omissions?

• A. General Liability
• B. Professional Liability
• C. Workers' Compensation
• D. Auto Liability

Answer: (B)

Professional liability insurance (errors and omissions) is the coverage tied to the architect’s design services. AIA B101 contracts are about the architect’s professional work, so the insurance needed to address claims of design errors, omissions, or negligence is professional liability. General liability covers third-party bodily injury or property damage from overall operations, not the architect’s design mistakes. Workers’ compensation covers employee injuries, and auto liability covers vehicle-related incidents. Thus, the insurance type covering the architect’s professional services is professional liability.
