Seismic Isolation Bearings for Bridges in Medium to High Seismic Areas

[VoyageofDiscovery]

Does anyone have typical costs for these type bearings used to retrofit short to medium span highway bridges?

Your state DOT should have unit prices available on their website.
Are you referring to elastomeric bearings or actual isolation bearings with the lead core? NYSDOT has unit prices available for elastomeric bearings. They're categorized by load carrying capacity. If you use their prices you would also have to include a cost for removal and a cost for bridge jacking.

You could also call a manufacturer.

Thanks.

I found it on Caltrans.
