In Hawkeye-Security Ins Co v. Vector Construction Co, 185 Mich. App. 369; 460 N.W.2d 329 (1990), the insured (Vector Construction) performed all concrete work involved in an improvement project at a wastewater treatment plant. When the owner of the plant discovered that the concrete Vector had used did not meet project specifications, Vector was forced to remove and repour some 13,000 yards of concrete. Vector sought indemnity from its insurance carrier pursuant to the terms of a comprehensive liability policy substantially similar to the policy at issue in this action. The Michigan Court of Appeals determined that the insurer owed no duty to defend or indemnify Vector because "the defective workmanship of Vector, standing alone," was not the result of, nor did it constitute, an "occurrence" within the meaning of the insurance contract. Vector, 185 Mich. App. at 378-379.
