Issues:
Long two-span curved girder bridge with top flange lateral bracing in exterior girder bays along entire length of bridge
Action Item:
Reevaluate guidance on top flange lateral bracing; may only be required in parts of the span (such as near the interior bent for multiple span bridges), depending on the assumed girder erection/construction sequence
Issues:
At another bridge site on this project where MSE walls were used, the piles were driven before backfilling; when backfill was applied, the piles moved; temporary bracing was required to stabilize
Action Items:
· Provide a note on plans to require temporary bracing of piles when pile driving precedes backfilling
· Collaborate with Geotech to determine the height of an MSE wall that would require pile bracing
