Both exhibit exposed rebar with varying <br />degrees of section loss. See Photo 8 dated 11/30/2022. <br />Throughout the intermediate diaphragms there are spalls up to 4 inches tall x 2 inches wide x 1 inch deep. <br />As this condition is in the diaphragm, no defect is warranted at this time. <br />Due to high water levels this element was not inspected during this investigation. <br />There are multiple vertical spalls/delaminations that span up to 6 feet in Girder 4 Bay 3 side all spans. There are similar <br />delaminations in Girders 2 and 3 in all spans that span up to 2 feet length of the girders. There is exposed rebar that exhibit varying <br />degrees of section loss. See Photo 7 dated 11/30/2022. <br />Non-Routine Inspection Element Notes: <br />UWI (05/28/2020): See Table 3 of the report from AECOM. There are 9 lineal feet (3 meters) of girder spalls with associated exposed <br />reinforcing with section loss. A hands-on inspection of exposed reinforcing steel was not possible by the diver.
