Title
Resolution to Approve Change Order 3 with Gerace Construction Company, Inc. for the 2022 Bandemer Park Bridge Repairs and Renovations Project (RFP 22-18, $86,035.00 Increase) (8 Votes Required)
Memorandum
Attached for your review and approval is Change Order 3 to the construction contract with Gerace Construction Company, Inc. for the 2022 Bandemer Park Bridge Repairs and Renovations Project (RFP 22-18).
The work included in Change Order 3 consists of drilling weep holes in the truss diagonal members of both bridges and installing a cover plate on the bottom flange of a pedestrian bridge floor beam. Additionally, after removal of the false decking that was preventing debris from falling into the river or onto passersby, several areas of deterioration that had not been noted previously were identified. This included an additional lateral bracing member that required repair, five lateral bracing members near the abutment that required replacement, two vertical truss members that required repair and 19 locations in the floor beams that required web repairs.
The original fabrication drawings show weep holes were intended per the plans, but they were not included when the structure was built. DLZ discussed the lack of weep holes with Contech, the truss fabricator, and their recommendation was to drill weep holes during the current construction project. Weep holes allow any moisture that gets inside the tube members to drain and prevents damage from occurring if water is trapped inside the tubes and freezes.
Additionally, steel section loss had developed to the point of creating holes on the bottom of one of the pedestrian bridge floor beams, and this was not identified until the beam was being cleaned prior to painting. The floor beam was last inspected in 2018 and it did not have any holes or notable section loss at that time.
Six lateral bracing members had deteriorated to the point that five of the members could not be economically repaired and were replaced. A sixth member was able to be repaired. These members are above the river and were not accessible during the 2018 inspection.
Two vertical truss member had cracks extending along the length of the members (splitting). At the time of the 2018 inspection, neither member had evidence of a crack or splitting.
After the false decking was removed, the remaining floor beams were able to be inspected. The floor beams were sounded with hammers to remove rust and scale from the beams, and once this was performed, holes were found in the webs of the floor beams and 19 web repairs were required.
