Manukau Rail Station redevelopment
KiwiRail developed the Manukau Rail Station as part of a new 1km rail spur to provide a direct connection to the Auckland CBD.
After earlier work to identify and evaluate options for the Manukau Interchange, Opus was awarded by KiwiRail the concept design of the Davies Avenue bus interchange and the rail station with all associated works adjacent to the site.
We provided architecture, transport planning & traffic engineering, stormwater and wastewater management, civil engineering, roading, geotechnics, surveying, planning and consenting, risk services, building services, and structural engineering.
Critical issues during concept design included accessibility issues, functionality associated with the pedestrian safety and traffic signals and platform access capacity issues. Our traffic engineers also worked on the effects on local bus networks, patronage forecasts and modelling expected future bus movements in the local area.
Opus prepared resource consents to enable construction and operation of the bus interchange and an interim station entrance building. Our design team was then novated to the Leighton Downer Construction JV to design the main station box including all the below ground civil drainage works. A number of design options were considered, which were reviewed by the combined project design and construction team taking into account costs and constructability.
A key strength of this project was the design and construction team working together to deliver the design for the station box, stormwater system and remaining consent applications. To facilitate a closer working relationship, our engineers worked closely with the construction team who were based in the same office.
