The project requires installation of new aluminum diamond plate flooring, pit ladder, stop switches, and buffers, along with cleaning, painting, and refurbishment of existing components including the freight elevator cab, safeties, and guide shoe inserts. No pricing information, contract terms, bid deadlines, or award dates are included in this specification summary document.
