Located in Moline’s Overlook District, the Deere-Wiman House and Butterworth Center were constructed in 1872 and 1892, respectively. These neighboring, historic mansions are now managed by a non-profit organization. Working with the preservation consultant, Sullivan Preservation, SGH assessed the structure’s condition and helped prepare a Historic Structure Report for both homes and the ancillary buildings.
SGH assessed the condition of several structures, including the mansions and their additions, carriage houses, and tunnels extending from the homes to their respective garages/carriage houses. For both properties, SGH performed the following:
Observed the structures’ interiors and exteriors to document the existing conditions and any readily visible deterioration
Documented structural damage, deterioration, and evidence of water infiltration
Provided repair and restoration recommendations to extend the useful life of the structures
Recommended additional investigation for certain components exhibiting significant structural damage
Prepared a report summarizing our findings, which were included in the Historic Structure Report and Preservation Plan prepared by Sullivan Preservation
