EMERGENCY - Black Hawk SHS Museum Window Dormer Repairs & Replacements

The Illinois Department of Natural Resources, Office of Realty & Capital Planning – Statewide Operations has awarded an emergency contract to Renaissance Restoration, Inc. on July 20, 2026 for historic window and dormer repairs at the Black Hawk State Historic Site in Springfield, Illinois. This was a sole-source award justified by the contractor's prior experience with the initial phase, specialized knowledge of unforeseen expanded conditions, familiarity with State Historic Preservation Officer requirements, and ability to mobilize immediately; three contractors were contacted but only Renaissance Restoration was qualified to proceed on an expedited schedule.

The scope includes full restoration of six failed dormer windows and structural repairs to address extensive water infiltration threatening irreplaceable museum artifacts and state property. Work comprises removal and restoration of deteriorated window sashes and frames, construction of six new 1-3/4"-thick 30-lite sash units from Sapele Mahogany in compliance with Secretary of the Interior Standards, replacement of sills and subsills, glazing with salvaged historic glass, application of linseed oil-based primers and urethane trim enamel finishes, replacement of deteriorated dormer trim, and State Historic Preservation Officer-approved repairs to failed wall and dormer beam support connections using modern concrete masonry with custom wood-cladding details to preserve historic appearance.

The total contract amount is $206,432.00, funded through state appropriated funds on an actual expenditure basis. Renaissance Restoration, Inc. is located in Galena, Illinois. The emergency procurement was justified by immediate necessity to prevent further water infiltration damage and mold growth risks, protect state records and artifacts, and prevent service disruption requiring museum closure. No Business Enterprise Program goals applied based on NIGP code calculations despite the contract exceeding the $100,000 threshold.
