The Duncan Shop Bus Hoist Replacement project involves the removal of twenty-nine (29) existing bus hoists consisting of twenty-three (23) standard 2-post hoists and six (6) 3-post articulated bus hoists. The project consists of fifteen (15) phases to ensure the day-to-day operation of the maintenance facility is not disrupted. Each set of hoists within a phase must be fully commissioned and put into service prior to proceeding to the next phase. Scope of work includes all structural, mechanical, and electrical modifications required to accommodate the installation of new in-ground cylinder post type hoists.
