The headquarters building of RLI, a publicly held specialty insurance company in Peoria, IL, had become dated and needed extensive interior and exterior repairs. Originally constructed in 1970, the 81,000 sq. ft. building‘s precast concrete facade had deteriorated significantly. To give the building a new look, RLI hired Dewberry Architects, Inc., Peoria. The firm considered many products to revitalize the building's exterior but ultimately chose zinc claddings from RHEINZINK America Inc. of Woburn, MA.
