A major water leak has closed Wisconsin’s Department of Administration headquarters in downtown Madison after a chilled-water pipe failed on the building’s penthouse floor early Monday, Sept. 14. The leak affected all 10 floors of the 101 E. Wilson St. building, according to an email sent to employees by Deputy Secretary Anne Hanson. Water reached key electrical areas, prompting officials to shut off power to the building, including its elevators. No one was injured, Hanson said. The water was shut off and contained relatively quickly, but crews are continuing to remove water and assess the damage. Wet carpeting and fallen ceiling tiles were reported in some work areas, although officials said the impact was not uniform throughout the building. The building will remain closed to the public and non-authorized employees through at least next week. Department employees have been directed to work remotely, with alternate work locations available and limited access to documents or equipment as needed. The Department of Administration said it is assessing the extent of the damage and carrying out remediation. The agency has not released the amount of water that entered the building or the number of employees who work there. The 10-story building, constructed in 1991 at the corner of East Wilson and South Pinckney streets, is the department’s headquarters and includes five levels of underground parking. It also houses the Wisconsin Office of the Commissioner of Insurance, the Board for People with Developmental Disabilities, the Wisconsin Ethics Commission, the Board of Commissioners of Public Land and the Tax Appeals Commission. The closure affects agencies involved in state operations, including budget development, oversight of state-owned buildings and construction projects, and administration of public grant programs. Capitol Police responded after an alarm alerted officers early Monday, though additional details about that response were not immediately available.
