The complaint alleges that, prior to September 25, 2023, Energy Control Service Inc., by its employees, agents, contractors, or subcontractors, negligently performed the work. On or about September 25, 2023, the sensors installed by Energy Control did not operate as intended and the building management system failed. As a result, the pump supplying water to the 23rd floor tank failed to shut off, causing the tank to overfill and water to overflow into and throughout the premises, including Norton Rose Fulbright’s commercial space.
