Midwest Mobile Diagnostic Imaging, L.L.C. (Midwest Mobile) (plaintiff) provided magnetic resonance imaging (MRI) services. Faced with increased demand for mobile MRI services, Midwest Mobile ordered four new trailers from Ellis & Watts, which was doing business as Dynamics Corporation of America (Dynamics) (defendant). Midwest Mobile instructed Dynamics to install MRI equipment in the trailers. Midwest Mobile included technical specifications related to the sensitivity of the MRI equipment. Midwest Mobile also emphasized interior-design standards. The trailers had to be aesthetically pleasing to meet the patients’ comfort expectations. The parties agreed on December 1, 1995 for the first delivery date. Midwest Mobile scheduled patients beginning December 4. Dynamics delivered the first trailer in late November. Midwest Mobile soon discovered that the trailer walls were unstable. Dynamics attempted to fix the problem by installing steel beams along the walls, and Dynamics redelivered the trailer on December 13. Midwest Mobile rejected the redelivered trailer, advising Dynamics that the steel beams were unsightly and interfered with the MRI equipment. Dynamics failed to offer additional repairs. On December 18, Midwest Mobile canceled the contract, and sued Dynamics for damages.
