About this file
This is a mechanical hydronic piping plan for the Illinois Secretary of State's boiler replacement project at the Chicago West facility located at 5301 W. Lexington Street, Chicago, Illinois 60644. The plan details the lower-level mechanical hydronic piping layout for the installation of two new condensing boilers (CB-2 and CB-3) to replace an existing water tube boiler. The design includes new piping connections for hot water supply (HWS) and return (HWR) lines ranging from 2 inches to 4 inches in diameter, integration with existing constant flow pumps (HWP-1 through HWP-4), a new chemical pot feeder, and a new 4-inch concrete housekeeping pad. The plan shows connections to existing boiler room infrastructure, including a 14-inch by 18-inch chimney shaft, existing combustion air intake, and floor drain relocation. A 12-inch stainless steel flue insert is specified for installation through the existing chimney shaft, with all piping penetrations requiring firestopping. The drawing was issued for 50% review on May 9, 2025, progressed through 75% review on August 13, 2025, 100% review on October 14, 2025, and was issued for bid on January 6, 2026, with subsequent addenda issued on April 20, 2026, and May 19, 2026.
The plan serves as a technical specification document supporting the competitive bidding process for the new boiler installation project. Bidders must be pre-qualified by the Illinois Capital Development Board and demonstrate seven years of documented commercial boiler installation experience. A mandatory pre-bid conference is scheduled for May 15, 2026, at 10:00 AM at the project site, with bids due on May 28, 2026. The work scope requires compliance with the Illinois Works Jobs Program Act and Apprenticeship Initiative, general commercial liability insurance of $1,000,000 per occurrence, a 10% bid bond at submission, and a performance bond for the full contract amount. The project will be awarded on a lowest-price-responsive-and-responsible-bidder basis with a firm, fixed total cost pricing structure. Contract work must be performed during normal business hours (7:00 AM to 5:00 PM, Monday through Friday) unless otherwise arranged, and the initial contract term is four years from execution with a maximum total term not to exceed ten years including any renewals.
