Many of the elements appeared to be replaced or repaired. There are newly painted non distorted <br />steel members which correlate to previous damaged members. Refer to Photo 8. <br />There are various spots where the primer coat is intact but the finish coat have faded on the steel truss members. Refer to photo <br />numbers 3 and 4 from the 2020 BIR and Photos 7, 8, and 9 from this inspection. <br />There were no significant defects noted. <br />Pack rust up to 0.37 inch thick was noted by the Fracture Critical Team at the gusset plate connections of the portal bracing to the <br />upper chord truss members. <br />There is a crack in the gusset plate at the right truss that joins the center floor beam to the east steady wheel beam at Pier 7. The <br />crack is located along a bend and weld in the gusset plate and is approximately 3.5 inches long. The crack does not appear to have <br />grown since the initial discovery by the Fracture Critical Team on 10/15/2003. <br />Non-Routine Inspection Element Notes: <br />Non-Routine Inspection Element Notes: <br />Non-Routine Inspection Element Notes: <br />Non-Routine Inspection Element Notes: <br />Non-Routine Inspection Element Notes: <br />Non-Routine Inspection Element Notes: <br />Non-Routine Inspection Element Notes: <br />NSTM (08/22/2023): See the report narrative for description of the defects (0.1 m in CS3). <br />NSTM (08/22/2023): See the report narrative for the list of members that were inspected. <br />NSTM (08/22/2023): See the report narrative for the list of members that were inspected. <br />NSTM (08/22/2023): See the report narrative for description of the defects (0.1 m in CS2). <br />NSTM (08/22/2023): See the report narrative for the list of members that were inspected. <br />NSTM (08/22/2023): See the report narrative for description of the defects (22 in CS3).
