EMU depot and stabling yard services a new fleet of passenger trains
We provided a range of planning and design services for KiwiRail in the early stages of this major project for Auckland Transport.
Auckland Transport needed an electric multiple unit (EMU) depot and stabling yard to service a new fleet of passenger trains. Opus provided master planning, concept design and costing advice for KiwiRail in the early enabling works of this $90M project.
For the subsequent detailed design for Auckland Transport, our designers considered the rail operations including the stabling facility and the running of the adjacent main line.
KiwiRail were tasked by the Government with procuring a site suitable for the maintenance of the new electric train fleet in Auckland. KiwiRail identified a site adjacent the main line in Wiri and Opus was selected as the consultant to provide master planning and concept design services for the project.
The first phase was to work with the client to define the operational requirements and develop a full brief for the project, including future proof allowance for fleet increases. The second phase was to produce a master plan and concept design for the site. We needed to manage a complex stakeholder environment to ensure all stakeholders’ requirements were understood and included.
Having resolved the site layout and key operational requirements, we successfully integrated the specialist plant and equipment required. We prepared performance specifications for this plant which the Client has procured independently from the main depot civil and building works.
In developing the design we looked at a number of alternate site layouts and assessed these against a matrix of criteria which took into account operational requirements. Throughout this project our fundamental approach has been to challenge assumptions to achieve the best balance between capital investment, through life operating costs, and operational efficiency.
Opus, in conjunction with international specialist Arup, provided the full range of services which included rail infrastructure design, architecture, structural, mechanical, electrical, environmental and geotechnical engineering.
We have subsequently undertaken the detailed design for Auckland Transport with
construction completion in 2013.
