~.~~... Elk~~ MEMORANDUM River TO: HRA FROM: Bob Ruprecht, Building Official DATE: 10/28/201 I SUBJECT: 716 and 720 Main St. NW I was asked by Annie Deckert, Director of Economic Development, to inspect the buildings at 720 and 716 Main St. in July of 2011 to identify areas that were leaking into the 716 building during the winter. At that inspection, I noticed the fractured truss in the 720 building and recommended contacting a structural engineer for inspection. Louks and Associates were contacted by the HRA and an inspection was completed on August 19, 2011. An informal report was prepared by Louks and presented to the HRA. It was determined that a formal property assessment needed to be performed to fully understand the complexity of a possible demolition of the buildings. In their preliminary inspection, Louks recommended that no one enter the building until a further detailed investigation and either the building is demolished or repaired. It is my concern that complete failure of the 720 roof truss may also cause damage to the 716 and 724 Building. The occupants of 716 Main St. (Elk River Area Arts Alliance) asked for the opportunity to conduct an inspection with their structural engineer. That inspection took place on October 27, 2011. Gregory J. Duerr, a structural engineer from Structural Design Associates, Inc., completed the inspection with me, Annie Deckert, Ron Touchette and David Raymond from the ERAAA, Denny Chuba of Chuba Construction present. The inspections by Louks and Associates and Structural Design Associates, Inc., confirm my determination that the 720 roof truss is nearing complete failure. Occupancy of the 720 building should be severely restricted. To ensure the structural integrity of the adjacent buildings, a snow mitigation plan should be developed for 720 Main St. to minimize the risk of a roof failure. Further, I recommend shoring the failing truss from below, which would substantially reduce the risk of failure until the property survey is completed and further actions are decided.
