The fluorescent lights of the maintenance bay hummed a low, electric B-flat, matching the vibration in Elias’s hands. On the steel workbench lay the Hilti SID 4-A22
, a veteran of a thousand deck screws and a dozen high-rise builds. It was silent now, its brushless motor choked by the fine, gray dust of a concrete demolition job. Elias smoothed out the parts diagram
