Notes
The Miller Park Baseball Stadium's retractable roof developed malfunctions within the first year of acceptance by the owner, Southeast Wisconsin Professional Baseball District. Hardesty & Hanover teamed with LZA for evaluation and rehabilitation services. This $7 million project included evaluation, inspection and operational tests on the mechanical and electrical systems of the movable roof that lead to the development of operational monitoring systems and replacement of the roof pivot bearings. Automated systems were designed to monitor the position and movement of the roof and the drive motor power output during roof operations.
New pivot bearings and housings were designed to replace the faulty existing bearings. Bearing replacement required: jacking each of the five roof panels; removal of the existing bearings; in-place machining of each of the bearing's receiving surfaces; and installation of the new bearings. The replacement bearings each carry 2 million pounds.
