This project involved the strengthening of the substructure of the Calliope River Bridge located outside of Gladstone on the Gladstone – Mt Larcom Road. The bridge comprises 9 spans, with Piers 1 to 3 founded on cast insitu piles and Piers 4 to 8 founded on PSC driven piles. The existing Pier 4 pile cap and piles were displaying unacceptable levels of deflection under traffic load and were affected by corrosion.
Works included construction of two new bored concrete piles offset to the existing piles at Pier 4, connected by a new headstock to encompass the existing Pier 4 columns to effectively make the existing Pier 4 piles and pile-cap redundant.
Civil Support was engaged by Transport and Main Roads to Superintend the Road Construction Contract (RCC), in a multi-stage process to fit with obscure design and funding constraints. As such, works were conducted intermittently between August 2010 and December 2013. Civil Support also provided resources in the role of Site Engineer at various stages throughout the project.
