Stepping up collaboration to support the transformation of New Zealand’s rail network


How Interdisciplinary Visual Collaboration Software Enables Efficient Delivery of New Zealand Rail Network Upgrade Projects

New Zealand’s rail network has connected people and goods across the country for over 150 years. KiwiRail is in the midst of an exciting transformation thanks to government investment of over $4 billion since 2017. This funding enables KiwiRail to provide more than just physical assets, as investment projects create an opportunity to also transform the operation of KiwiRail. .

The New Zealand government has presented its 10-year vision for rail as part of the NZ Rail Plan. It also represents a historic change in the way the rail network is planned and financed in New Zealand. In July 2021, the first Rail Network Investment Program (RNIP) came into effect, which sees transport agency Waka Kotahi NZ fund rail infrastructure from the National Land Transport Fund (NLTF), providing a long-term infrastructure investment pipeline.

From 2020 to 2024, KiwiRail’s Wiri to Quay Park (W2QP) project is one of many investment rail projects powered by Revizto. As KiwiRail revitalizes the busy junctions of Westerfield and Wiri and builds the third main track to separate slow moving freight trains from faster commuter trains, Revizto acts as the key coordination tool that brings the delivery team together in one single-source-of-truth collaborative environment.

Derek Jannings, Head of Digital Engineering at KiwiRail, explains how Revizto supports the delivery of the Wiri to Quay Park project throughout the project life cycle. Derek shows us how Revizto helps achieve shared results for all stakeholders involved.

“Revizto is our golden thread on the project. It is used in design and construction coordination meetings to troubleshoot issues and provide visual context, drive conversations, and allow the W2QP team to resolve complex issues before performing site work.

As rail is a living environment, access to the network for the construction of complex infrastructure means that the planned works must be completed within the agreed deadlines. KiwiRail has taken a bold approach to providing licenses to their supply chain which they work in collaboration with to complete projects. This means that everyone has access to Revizto on the project and 3D and 2D information is democratized. For KiwiRail, the cost of uncoordinated onsite issues is significantly higher than providing licenses for Revizto.

The challenge of delivering complex rail infrastructure projects on time and within budget

Without a collaboration tool, complex rail infrastructure projects can be difficult to deliver on time and on budget. There are a number of different stakeholders who support the delivery of KiwiRail projects, and this is often done using a range of design authoring software for specific disciplines. Before Revizto, KiwiRail lists the particular challenges encountered from a technical point of view.

  • Disjoint information located in multiple places
  • Designers or consultants using discipline-specific pattern-making software who cannot access other design patterns
  • Multiple issue tracking logs (spreadsheets) on projects that were unrelated to visual information
  • Rich 3D information is limited to specialist BIM practitioners

KiwiRail’s transformational digital engineering program is changing the way projects are delivered

KiwiRail’s transformational digital engineering program changes the way projects are executed and seeks to leave the company with more than physical assets, but also rich digital assets at the end of this breakthrough investment period. A consistent approach to large-scale collaboration environments across our portfolio is key to delivering these assets.

  • Designs are now connected and coordinated in one place
  • Democratized information, 3D models are available to everyone – not just BIM specialists
  • Visual background. Stakeholders can be brought into the Revizto environment to provide meaningful input into the design. Teams are more aligned and on the same page

“Design updates are uploaded fortnightly along with monthly as-built models – the as-built models are then integrated into the design environment. This allows the team to always coordinate with the latest information and update them when necessary adjustments are needed, reducing risk and on-site errors.

Derek Jannings, Digital Engineering Program Manager

“Using Revizto as a collaborative environment on projects allows us to significantly reduce risk and errors during construction. Because we work in an active rail environment, when we have access to the rail corridor to perform construction of infrastructure, it is essential that we complete the works within the given deadline, this means that things must be coordinated!With Revizto, everything went according to plan.

Next level coordination with Revizto

The breadth of the W2QP project means that there are a number of different workflows at different stages of a project’s lifecycle. This means that due to tight timelines, the construction and design work for the project is happening at the same time. KiwiRail receives monthly as-built models and imports them into Revizto to coordinate them with the proposed design models. This allows for the next level of coordination for the project, further reducing the likelihood of issues needing to be resolved on the spot.

Remove barriers to interoperability

For KiwiRail and the W2QP project, Revizto is more than just a design information platform. Monthly as-built drone surveys, as-built models, existing underground services, and rail-specific track gauge clearance models. Revizto is also able to host 3D models developed in rail-specific software, such as overhead line models. The ability to integrate 3D lane clearance models into the platform allows the W2QP project to coordinate tight tolerances for the design of overhead lines and signals at the Wiri and Westfield junctions. These are the busiest junctions in the New Zealand rail network and therefore require a high level of precision when coordinating new assets.

Powerful Features of Revizto for KiwiRail

Multiple search sets – Research sets in Revizto allow KiwiRail to democratize a large number of models and design disciplines on their projects and then make them available to a wider audience on a single platform. Project teams unfamiliar with object trees can easily filter models through object properties or predefined areas, giving KiwiRail actionable insights.

Custom properties – Custom properties in Revizto are essential for the success of KiwiRail on W2QP. With an industry-specific railroad, the expertise comes from KiwiRail’s need to think outside the box with traditional authoring tools and bring together expert input from project stakeholders through custom settings in the templates. railway clearance.

Multi-stamping and issue tracking – Prior to Revizto, KiwiRail handled spreadsheet-based issue logs with no visual representation, which caused ambiguity with team collaboration workflows. Issue tracking solves this communication problem between KiwiRail’s design and construction teams with predefined metadata, markup reviews, defect detection, and data visualizations with granular detail.

Bookmarks and tooltips with object-based navigation – Access to fast, real-time data is extremely critical for the delivery of time-sensitive WQ2P projects. KiwiRail uses these two Revizto features to bring location-based data and visuals closer together when switching between parallel workflows to eliminate bottlenecks and focus on high-priority items in a compressed project schedule.

“Revizto allows us to prioritize issues that need to be addressed before the physical construction work is scheduled. Teams are working collaboratively to resolve any issues in the digital world before construction begins: we are under tremendous time pressure, and there is no room for error.
