546-070-028-01 | Replace Roofing Systems

The General Jones Readiness Center (H0505) is a 3-story building constructed in 1929.
This project includes the complete replacement of aging roofing systems at the General Jones Army National Guard Readiness Center in Chicago, Illinois. The facility is approximately 294,720 square feet and includes approximately 155,563 square feet of existing roofing systems. The existing roofs include approximately 75,800 square feet of steep-slope standing-seam metal roofing installed in 1993, approximately 44,460 square feet of low-slope modified- bitumen roofing installed in 1993, and approximately 35,303 square feet of low-slope single-ply membrane roofing installed in 2013. The scope of work includes, but is not limited to, removal and replacement of the existing standing-seam metal, modified-bitumen, and single-ply roofing systems with comparable new roof systems. The project also includes replacement of approximately 1,000 linear feet of existing gutters and associated downspouts, originally installed in 1979. Work includes, but is not limited to, new roofing materials, insulation, underlayment, flashing, trim, roof-edge components, drainage components, transitions between roof systems, penetrations, rooftop equipment coordination, and all necessary accessories to provide complete, watertight roofing and drainage systems.
The project will include an environmental inspection of the existing roofing materials before demolition activities. The project also includes investigation and repair or replacement, as necessary, of roof-deck or supporting components identified during the detailed design and construction phases.
Hazardous materials may be encountered.
The State Historic Preservation Office should be consulted during every phase of this project.
The A/E shall assess the project for eligibility under applicable utility incentive programs, energy grants, rebates, and other funding opportunities. The A/E shall identify all qualifying programs and shall prepare, coordinate, and submit all required applications, calculations, supporting documentation, and related materials necessary to obtain available incentives for the project.
The A/E is encouraged to include independent cost estimators on their teams to verify estimates are in line with current market conditions to avoid project bids that exceed the available funding for the project. The A/E estimates should be updated and verified at each stage of the project in accordance with the Design and Construction Manual. Designers are reminded that their Professional Services Agreements make them responsible for providing a design that is within budget, and they can be held responsible for redesigning the project should the bids received exceed project funding.
The design will need to comply with the Illinois Stretch Energy Code. The Professional Services Agreement shall be executed no later than May 2027 and the project must be designed and bid to allow for construction notice of award no later than August 2028. The following A/E goals are applicable to the A/E team:
