Skanska USA Building, Inc. v. M.A.P. Mechanical Contractors, Inc. (Opinion - Leave Granted)Annotate this Case
Plaintiff Skanska USA Building Inc. served as the construction manager on a renovation project for Mid-Michigan Medical Center–Midland (the Medical Center); plaintiff subcontracted the heating and cooling portion of the project to defendant M.A.P. Mechanical Contractors, Inc. (MAP). MAP obtained a commercial general liability insurance policy (the CGL policy) from defendant Amerisure Insurance Company (Amerisure). Plaintiff and the Medical Center were additional named insureds on the CGL policy. In 2009, MAP installed a steam boiler and related piping for the Medical Center’s heating system. MAP’s installation included several expansion joints. Sometime between December 2011 and February 2012, plaintiff determined that MAP had installed some of the expansion joints backward. Significant damage to concrete, steel, and the heating system occurred as a result. The Medical Center sent a demand letter to plaintiff, asserting that it had to pay for all costs of repair and replacement. Plaintiff sent a demand letter to MAP, asserting that MAP was responsible for all costs of repair and replacement. Plaintiff repaired and replaced the damaged property, at a cost of $1.4 million. Plaintiff then submitted a claim to Amerisure, seeking coverage as an insured. Amerisure denied the claim. The issue this case presented for the Michigan Supreme Court's review centered on whether the unintentional faulty subcontractor work that damaged an insured’s work product constituted an “accident” under a commercial general liability insurance policy. Because the Court concluded the answer was yes, it reversed the Court of Appeals’ judgment to the contrary.
