What Are the Key Differences Between AIG and Aon General Liability Insurance?

Construction Risk and Covered Operations

Aon lists general liability within construction liability and describes third-party injury or property damage tied to negligent acts during construction or operations. AIG's catalogue names general liability only within selected programs and does not state occurrence triggers or covered operations. Contractors should compare each submission against job types, project contracts and insured operations, since Aon's practice-page summary also leaves policy triggers and exclusions to the proposed form. [1] [2]

Advisory Scope and Policy Terms

Aon describes project-specific risk advisory and risk-transfer planning for contractors, owners, developers, engineers and related parties. AIG describes program support through program administrators, including underwriting and loss control. These services arise from different distribution structures; ask Aon how advice shapes project placement and ask the AIG program administrator what services attach to the quoted policy. [1] [2]
