Sydney Harbour Bridge Arch Maintenance Units (AMU)

Project lifecycle

We offer services to improve business performance by providing expert advice on all phases of a project lifecycle, from initiation to finalisation


RMS (now TfNSW) is proposing the replacement of the four existing Arch Maintenance Units (AMU) on the Sydney Harbour Bridge. The dated AMUs are to be replaced with new infrastructure consisting of two cranes at each end that span between the top chords of the bridge.

The works are needed to provide safe and efficient maintenance access to the full bridge arch and lateral steel members.  The work scope will include replacement of existing stairs, handrails, tracks and power reticulation on the top chord.

CJC role

RMS engaged CJC to undertake an initial Constructability and Risk Workshop. The purpose of the workshop was to discuss the likely construction process with the RMS project team members, key project personnel and stakeholders, as well as identifying constructability issues and opportunities.

The initial Constructability and Risk Workshop focused on the installation works and did not consider the off-site manufacture or transport of components to Australia.

CJC prepared a Constructability and Risk Workshop Report outlining the outcomes of the initial workshop. This advice is to be considered in further developing/progressing the project.
