Pulaski Skyway

Under the Pulaski Skyway Rehabilitation project, SJH provided inspection of the superstructure and substructure elements from Pier 79 to 98 including the truss structure over the Passaic River. Field work includes in-depth inspection and documentation of existing conditions of all steelwork between Piers 79 to 98 including trusses, gusset plates, truss bracing members, floorbeams, stringers, purlins and secondary members. Substructure inspections included hammer sounding of all faces when possible. SJH developed repair of steel elements of the bridge including bearing replacements.

Based on the field inspection, SJH identified items that required priority repair recommendations and prepared priority repair reports. We organized field notes, prepared CADD sketches and photographs for the final inspection report. We also prepared a summary inspection report consisting of findings and recommendations at the end of inspection.

In addition, SJH reviewed pier seismic analysis results. For any members or components that had C/D ratios less than 1.0 and were determined to require retrofitting, SJH developed alternatives including structural calculations to determine the required member strengthening details and cost estimates to assist in the evaluation and selection of the most cost effective retrofit scheme.

Upon NJDOT’s approval for the recommended seismic retrofit schemes, SJH prepared contract plans for the pier seismic retrofit and any pier modifications that may be required to facilitate the replacement of existing steel rocker bearings with seismic isolation bearings.
