A moving truck, exceeding the garage height limit, proceeded to enter the parking garage structure and hit a stem of a precast double-tee at an estimated 20+ mph while traveling the first level ramp. The damage to the double-tee was very significant and called for immediate lane closures, emergency shoring and a review / repair design by a structural engineer. The double-tee damage occurred due to head-on impact which fractured approximately the middle one-third (1/3) of one (1) each double-tee stem. The damaged area of the stem had approximately twenty-five (25) linear feet of concrete that needed to be removed and replaced. The design called for the installation of structural steel components to support the span of the tee during and after permanent structural concrete repairs.
