Fast Facts

Auckland City Hospital is a complex stakeholder environment with patients, staff, specialist service providers, emergency vehicles and a helicopter pad all intersecting within a small footprint in central Tāmaki Makaurau, Auckland.
The project team planned the construction method to suit the 24/7 live hospital environment and minimise disruption to stakeholders by creating a custom traffic management plan, including an access ramp so large vehicles like trucks could be separated from hospital traffic.
Dust, noise and vibration impacts were monitored closely during construction via SiteHive, an innovative environmental sensor capable of tracking data levels to ensure the project complied with resource consents. The real-time readings allowed the team to promptly adapt any methods that caused noise or vibration to exceed permitted levels.
The McConnell Dowell and Built Environs joint venture has completed complex projects across Australasia and draws on their collective experience in piling deep foundations, open-trench tunnelling methodologies, and building multi-storey vertical structures.
Work on this project will include:
Services Tunnel
The 4m x 3.5m services tunnel connects the existing support building A01 to the new building A40, and includes an extension to the west for future development. The extension will eventually provide a services tunnel ring main through the campus. The tunnel works includeed large diameter retaining piling, bracing, deep excavation and large reinforced concrete sections cast in situ.
Central Plant Building
The five-storey A40 building is a concrete-framed structure with precast concrete and glass cladding, designed to be earthquake-resistant with bespoke triple-friction pendulum bearings to increase seismic resilience. The facility must be operational after an earthquake or other disaster, so it also features a backup electric generator to manage services during a power cut.
The building was constructed with deep 7.5m to 26m foundations and includes double-height spaces for large chiller and generator halls, as well as a roof-level double-height cooling tower. The building is also future-proofed as a Health Alliance data centre.
Plant and Equipment Installation and Decommissioning of Building A06
The Central Plant and the Services Tunnel has been fitted out with all the necessary plant, equipment, and services to reduce the reliance on the A06 Building. Following the installation of the services, there will be a period of commissioning which will need to be carefully staged and managed to reduce disruption.
