The Waterview Tunnel is New Zealand’s largest and most complex road infrastructure project to date, and is the longest road tunnel in the country. It is a key part of the Western Ring Route, a 48 km highway that runs through West Auckland and connects Manukau, the city, West Auckland and North Shore.

The project consists of a 5 km highway with 3 lanes in each direction and includes a 2.5 km fully equipped double-deck tunnel linking State Highway 20 (SH20) with SH16.

SICE was appointed as a 50% partner of the Alliance for the design, supply, installation, testing and commissioning of the Operations Management and Control System (OMCS), the Mechanical and Electrical (M&E) Systems and all the ITS subsystems. All tunnel systems are controlled by the OMCS developed by SICE.

SICE supplied the following systems for the project:

• Operations Management and Control System (OMCS)
• CCTV and Digital Video Management System (DVMS)
• Automatic Video Incident Detection System (AVIDS)
• Traffic control system
• Voice communication systems (METS, FETS, IOCS)
• Hosting platform and control room equipment (workstations, video wall)
• Tunnel Closure Systems
• Overheight Vehicle Detection System (OHVDS)
• Vehicle detection systems
• Radio and mobile relay systems
• Public address systems
• Signalling (VMS, TMS, LUMS/ISLUS, VSLS)
• Motorway Network Communication System (MNCS) (fibre, switches, firewalls, etc.)
• PLC network (PLCs, Remote IOs, switches, cabinets, etc.)
• Ramp measurement system
• Electrical system (HV, LV, lighting)
• Ventilation system
• Fire detection and suppression system
• Tunnel drainage system
• Tunnel hydrant network

After completion, SICE took on the lead role, with a 40% stake, in the Waterview Tunnel Joint Operation (WTJO), the Alliance responsible for the Operation and Maintenance (O&M) of the tunnel for 10 years, until 2027. As Alliance leader, SICE is responsible for the maintenance of the OMCS supplied as well as all mechanical and electrical (M&E) equipment and all the ITS subsystems.
