The Interstate Route H-1 Seismic Retrofit Waialae Viaduct involves upgrading the existing Waialae Viaduct concrete footings and concrete columns.
Scope of Work includes installing fiber reinforced polymer (FRP) fabric to the viaduct girder, beams, and columns, strengthening the column foundations with an additional concrete pilecap.
