  • Auckland Harbour Bridge Maintenance Contract
    Auckland, New Zealand

    This contract is for the management and maintenance of the Auckland Harbour Bridge (AHB). In addition to the head contract, several significant variations have been awarded to Total Bridge Services (a joint venture between SRG Global, Opus and Fulton Hogan) over the course of the contract period.

    In 2013, the original AHB performance specified maintenance contract (introduced in 1999) was replaced by a new three year sub-alliance contract, which sits within the greater Auckland Motorway Alliance. The AHB sub-alliance is still responsible for all maintenance activities on the structure as well as the development and implementation of an asset management plan and a new containment system.

    Approximately 90 percent of the AHB is located directly above the Waitemata Harbour, with the remainder over land and tidal zones. Our proactive approach to working within a sensitive environment is overviewed by the Auckland Council with annual compliance audits completed. Environmental effects have been covered as part of our work procedures and we have implemented systems that contain any spills, despite working over live waterways for the majority of the time.

    As part of our activities on the AHB we have had to work with a wide variety of stakeholders, including residents, local businesses, traffic control, the NZ Police and emergency services. Each stakeholder has needs that we have had to respond to differently to ensure a positive relationship is maintained with all parties.

    The AHB is a hazardous site due to the fact the much of the structure has to be accessed using suspended stages, gantries or fall arrest techniques. The age of the structure also meant that many of original safety systems from the late 1950’s had become completely outdated and no longer complied with legal requirements. Since SRG Global was awarded the initial contract, significant upgrades have been made to ensure improved safety for staff while working on the bridge. This has included the construction of new service walkways, replacement of handrails, upgrades/replacement of stairs and the installation of meshing under the carriageway to prevent items from the road deck landing on workers below.
