About this file
This document is a Scope of Work specification summary prepared by the State of Colorado, Design & Construction Management for the modernization of Freight Elevator #3 located at the State Office Building, 201 East Colfax Avenue in Denver, Colorado (Project 2024-070M23). The project involves the complete modernization of a single freight elevator with a 2,500-pound capacity operating at 200 feet per minute, servicing six primary floors plus an alley entrance. The scope of work encompasses replacement of the existing Otis geared hoist machine with a new permanent magnet AC gearless hoist machine, installation of new programmable microprocessor controllers compliant with ASME A17.1-2019 standards, upgrade of power-operated front freight doors with sequential closing operation, installation of new hoistway entrances with bi-parting door panels, and replacement of all related mechanical and electrical components including hoist cables, governor equipment, door tracking systems, and counterweight adjustments. Additional work includes cab refurbishment with new aluminum diamond plate flooring, installation of new signal fixtures and pushbutton stations, pit ladder and safety devices per current code, and comprehensive fire service integration with addressable smoke detection and three interface modules for primary floor recall, alternate floor recall, and machine room notification systems.
The specification document does not provide pricing information, contract award dates, response deadlines, bidder conference details, site visit requirements, or contract term information in this summary excerpt. The document explicitly notes that this summary is a brief outline and that if any discrepancy exists between the summary and the full technical specifications, the complete technical specifications should take precedence. The project represents a significant capital improvement initiative for state elevator infrastructure modernization with emphasis on compliance with current safety and fire service codes.
