Lake County Forest Preserve District retained The Hezner Corporation to develop an approach to forensically analyze and develop construction documents for a roof replacement on the Brushwood Center, located in the Ryerson Forest Preserve, in Riverwoods, IL. The Brushwood center was originally the Ryerson family summer home and is designated on the National Historic Registrar as having historical significance. The planned replacement was a balancing act between historical interpretation and required technical corrective measures that resulted in a truly successful project for the Ryerson Forest Preserve.
