Golden Ears Way Bridge Deck Rebar Assessment During DBFM Period
Golden Ears Way Bridge required an assessment to check for indications of corrosion activity during the DBFM project’s 30-year concession period. Modern, non-destructive evaluation methods were used to assess the corrosion potential of the bridge deck rebar and determine any remedial maintenance required to reduce overall operation costs.
A deck rebar condition survey was completed on the structures at Golden Ears Way, comprised of 12 separate bridge structures totalling 95,000 square metres of deck area. The project was undertaken at the ten-year service life milestone to assess for indications of corrosion activity as part of the inspection and monitoring of the structures during the DBFM project’s 30 year concession period. A modern, non-destructive evaluation method was used in localized deck regions to assess the corrosion potential and rate of the bridge deck rebar. This approach provided a cost-effective method of assessing the bridge decks and determine if any remedial maintenance interventions are required to reduce overall operations costs.
This session was initially presented at the 2020 TAC Conference.
