ST. CHARLES – A local company that specializes in making products for manmade ponds and backyard water features has filed suit against eight other construction-related businesses, alleging they are liable for the 2011 collapse of a large “green roof” at the company’s St. Charles headquarters.

Aquascape Designs Inc. of St. Charles and Wittstock Family of Wayne brought the action in Kane County court late last month, seeking $13 million in damages from the various contractors, led by Artisan Design Build, of Monroe, Wis.

Other businesses named in the suit include Olsson Roofing of Aurora; Tecza Landscape Group of Elgin; Tricon Construction Management of Dubuque, Iowa; Senektekts of Monroe, Wis.; NCI Group of Houston, Texas; Area Erectors of Rockford; Applied Ecological Services of Broadhead, Wis.; and Dewberry Architects of Fairfax, Va.
