Sinclair Knight Merz lands Sydney Harbour Bridge contract

10 Jul 13 Sinclair Knight Merz (SKM) has been appointed by RailCorp to assess railway deck and transom replacement strategies for the Sydney Harbour Bridge.

The iconic Australian bridge carries eight road-traffic lanes, two railway lines and separate pedestrian and bicycle pathways. The decking and transoms supporting the railway track currently require regular cyclical maintenance over short intervals because of the design life of the material used.

SKM will be evaluating the replacement of the existing high-maintenance timber with more durable components.

In advance of the study, SKM will be using 3D laser scanning to carry out a survey across the rail corridor to facilitate concept design.

The project will draw on design and construction work carried out by SKM in the UK where fibre-reinforced plastic was used to re-deck two Network Rail Bridges at Calder Viaduct and Rubha Glas.

SKM technical director Professor Sam Luke said: “It’s an honour to bring our multi-disciplinary team together to work with RailCorp, as well as NSW Roads and Maritime Services on this symbolic piece of infrastructure.”
