One of the best ways to manage risk on construction projects is through insurance and bonds. Throughout the next several weeks, the AIA Contract Documents Program is going to release a series of articles pertaining to construction insurance. This is Part 6: Additional Insureds.
All parties to a construction contract obtain insurance through their own insurance carriers. In some instances, however, each party will add another party (or parties) to their insurance policies as “additional insureds.” The designation as an additional insured brings with it several attributes.
First, “additional insured coverage is intended to cover the vicarious liability of the additional insured arising out of the operations of the named insured.” Stated differently, if the negligence of the named insured (say, the contractor) could lead to liability for another party (say, the owner), then the owner is covered by being named as an additional insured on the contractor’s insurance policy.
Second, as a general rule, an insurance company cannot sue its own insured for things like reimbursement of claims payments. Being added as an additional insured gives this layer of protection to the party added as an additional insured, such that they cannot be sued by the insured’s liability carrier.
The effects of additional insured status are somewhat similar to those from a waiver of subrogation, which was discussed in Part 4: Waivers of Subrogation. Of course, there are many more aspects to additional insured status, but those listed above are some of the more critical ones.
Do AIA Contracts Contain Insurance Requirements Related to Additional Insureds?
