This is a site location and schematic work area map document prepared by Trivers Associates, Inc. for the Illinois Department of Natural Resources Old State Capitol restoration project located at S 6th Street and E Adams Street in Springfield, Sangamon County, Illinois. The document provides architectural elevations and site plans for an emergency window replacement project at the Old State Capitol State Historic Site, with CERP Code OSC-27-034. The project involves the restoration and replacement of twenty-three failed historic windows across multiple floors of the building, including the ground floor (100'-0"), upper floor (117'-2"), observatory floor (156'-3"), and top of cupola (207'-7"). The site is located in Township 16 North, Range 5 West, Section 34, as identified on the Springfield West Quadrangle map. The architectural drawings, dated May 12, 2021, represent the 100% construction document set prepared under Project No. 104-600-018.

The work area maps and elevation drawings depict the full extent of exterior and interior restoration work required, including stone masonry repointing, reinstatement of salvaged stone steps and caps, preformed roofing panel installation, counterflashing, and flat seam metal wall panels. The drawings indicate work on all four building elevations (north, east, south, and west) and identify specific restoration requirements through detailed keynote legends. The document also references related restoration and elevator upgrade work at the facility. As this is an emergency declaration notice rather than a formal solicitation, specific pricing, contract terms, timeline requirements, and bidding procedures are not detailed within these architectural plans. The project is under the purview of the Illinois Department of Natural Resources and represents a historic preservation effort for the state-owned Old State Capitol State Historic Site.
