A structural connection links an existing hollow structural section (HSS6x6x1/4) and an existing W21x49 steel beam supporting a metal deck adjacent to an 8-inch concrete wall. The connection incorporates a 1/2-inch plate and requires selective demolition of existing plates above and below the HSS section. Installation procedures require removing existing 7/8-inch diameter nuts and washers after angle installation, alongside typical bolt hole spacings of 1-1/2 inches, 3 inches, and 6 inches.
