AEROmetrex Creates 3D Reality Model to Reduce Sydney Congestion - Reality Modeling Solution for Sydney’s Parramatta Light Rail - 1

CASE STUDY Project Summary Organization AEROmetrex Solution Reality Modeling Location Parramatta, New South Wales, Australia Project Objectives • Create a 3D model for all aspects of planning, route selection, estimating, and consultation. • Unify data for all disciplines and create a federated dataset for a 3D framework. Products Used Bentley AXSYS, ContextCapture, OpenRail Fast Facts • The Parramatta Light Rail project was AEROmetrex’s largest highresolution ContextCapture project, covering 19.6 square kilometers. • The project team used ContextCapture to edit and retexture the 3D models, providing high data integrity. ROI • AEROmetrex photographed approximately 60,000 images of the corridor over a period of six weeks and processed images in only 26 days. • The team completed the model in 45 days by using Bentley applications to edit the 3D model, meeting their project deadline. AEROmetrex Creates 3D Reality Model to Reduce Sydney Congestion Bentley’s Reality Modeling Solution Processed 60,000 Images in 26 Days for Sydney’s Parramatta Light Rail Designing a New Rail Line Connecting the Greater Parramatta Area In November 2016, Australia’s Department of Transport New South Wales (NSW) commissioned AEROmetrex, a world leader in reality modeling, to design the Parramatta Light Rail. The Parramatta Light Rail project was designed to facilitate the shift of Sydney’s population center to the west. Like many large cities, Sydney, Australia is experiencing rapid growth and unsustainable property prices. The city cannot expand to the east, north, or south due to physical barriers, so it is moving west toward the Greater Parramatta area. By 2036, it is estimated that more than half of Sydney’s population will be centered in this area. There are already developments in place for new residential and commercial locations, a new health precinct, and better access to the Sydney Olympic Park facilities. The challenge, however, is that existing public transportation and rail networks are inadequate to handle these developments. The Parramatta Light Rail project will help ease some of Sydney’s most congested traffic routes and reduce commuting times. AEROmetrex was retained to create a 3D reality model of the proposed rail network route. This model would be used for preliminary route selection and, later, for community consultation and as a surveying data source. The reality mesh would cover an area of 19.6 square kilometers, or about 7.55 square miles. AEROmetrex needed to create a 3D model that would be used for all aspects of planning, route selection, estimating, and consultation. The project team wanted a model that would help unify data for all disciplines involved in the project, as well as to create a federated dataset to use as the 3D framework for the project. safer for the surveyors because they did not have to be on the ground on a busy road or rail corridor. It also helped reduce traffic congestion; any ground-based methods would have added to Parramatta Road’s congestion, requiring specialist traffic management companies to manage any stationary surveying. The reality mesh was then scaled to GPS-surveyed ground control using Bentley’s ContextCapture to provide a final overall accuracy. It took about 10 weeks to create and deliver the 3D model to the client. The project team edited and retextured the 3D models, providing high data integrity on features that were of special interest to AEROmetrex’s client. The team also created a “true ortho” of the area, a scalecorrected 2D image where all the features, including the one above the terrain surface, were represented in their true position. This feature ensured that no details were obscured by buildings or trees. Providing a Single Source of Truth AEROmetrex’s 3D model improved collaboration between stakeholders by adding interpretability and context to all forms of other data. It created a single source of truth and provided easy incorporation of design models and underground services. The model can be displayed and used Creating a 3D Model from Photographs The Parramatta Light Rail project was the largest highresolution ContextCapture project undertaken by AEROmetrex. To create the 3D model, the project team photographed nearly 60,000 images of the corridor from a low-altitude oblique perspective using a helicopter over a period of six weeks.

"The application of Bentley's ContextCapture reality modeling to a large, expensive, and high-profile political project is a long step forward in the adoption of this technology for serious engineering applications. This is no longer a 'recent disruptor' technology. It is the future of mapping and surveying." - Mark Deuter, Managing Director, AEROmetrex Pty. Ltd. with all Bentley applications. The project has delivered a holistic, interdisciplinary, and federated dataset, creating a solitary location where users can trust that the information is accurate. The design models could also be...
