oderna Inc. is suing construction firm The Gutierrez Co., alleging defective work at its Marlborough manufacturing facility led to extensive water leaks, mold, and structural damage. According to a report by Boston Business Journal reporter Hannah Green, the lawsuit claims Gutierrez failed in designing and constructing the building's core and shell.

    Problems cited include mold in the roof system due to moisture, water infiltration across various systems, and dislodged exterior metal panels. Moderna is seeking over $10 million in damages, stating it must now fund repairs after completing its purchase of the property in April 2023.

    Gutierrez was responsible for overseeing construction teams and design professionals, but allegedly failed to do so properly, according to the complaint. The firm has not responded to requests for comment. Moderna, headquartered in Cambridge, is Massachusetts' second-largest manufacturer, known for its mRNA-based vaccines, including those for Covid-19 and RSV.
