FAQ
Work follows the elevator safety code (ASME A17.1 / CSA B44) as adopted in Illinois, and devices are licensed and inspected by the Office of the State Fire Marshal (with the City of Chicago for Chicago buildings).
Usually several weeks per car, depending on scope. We phase multi-car buildings so at least one elevator keeps running.
Equipment age and type, controller generation, parts availability, inspection history, callback log review and a recommended scope.
Yes — car controls, signals, door timing and, where needed, platform or LULA lifts.
When parts for the controller are hard to source, callbacks are rising, or inspection orders keep recurring. A condition survey shows whether you're there yet.

Compliance
Chicago metro
For larger Bolingbrook buildings we sequence modernization car by car, coordinate with property management, and keep at least one elevator in service throughout.
Typical scope in Bolingbrook: new controller and drive, door operators and restrictors, hall and car fixtures, and — where needed — machine replacement. Shaft, rails and car frame are usually retained.
Cold winters, road salt and grit wear door sills and tracks, and hydraulic cars slow down in unheated spaces.
