Eagles Oversight Investigation
Bill Dodd and Bruce Beechie inspected the Eagles Club on June 5. The area of concern was in the main hall at the northeast corner of the building. Tile separations and radial cracking are evident. They installed two crack monitors. One is located in the main hall near the kitchen access window and the other is located about 2 ½ feet north of the men's restroom at the northeast corner of the building in the hallway. The crack in the dining room floor appears to be a separation joint. The widest crack is below MP-1 near the kitchen access window and measures .2 inch or approximately .5 centimeters. Photographs were taken of the cracks/separations.
Loren Daede, City of Beulah Engineer and Shirley Oyen, Eagles Club Manager were present. Shirley said she would keep and eye on the crack monitors and do her best to protect them. Bill Dodd and Bruce Beechie will periodically check the crack monitors and keep a log of measurements. The following are pictures of the floor:
