Bergmann served as the owner’s representative overseeing the demolition of this 92-year-old, double track, through-truss swing bridge that is potentially eligible for the National Historic Register. Demolition included full removal of the 304-foot-long through-truss, control house and machinery, timber starkwaters (end rests), timber fender system and pilings, center pivot pier and pilings, as well as contaminated sediment dredging and disposal. Salvage and restoration of select bridge components for historic mitigation was also conducted.
As the owner's representing Bergmann developed the demolition plans, specifications, cost estimates and contract documents for removal of the bridge. Bergmann also procured the demolition contractor using a two-step pre-qualification and BAFO process, served as the client’s structural technical advisor for the environmental permitting process and provided construction phase administration and inspection services.
