Reviewers are invited to provide case studies in their portfolios that provide illustrations of:
- infrastructure data currently in use
- intended future uses of infrastructure data
- projects or assets that were impacted by a lack of structured data interchange
- novel uses of data combining different data assets
- application of standards to facilitate data interchange across systems
Case studies will be used within the body of the document as context for key points.
This current Appendix will not form part of the final document.
User Case Study: Applying Digital Engineering to support the development of Circular Quay
The Circular Quay Precinct Renewal project will upgrade the Circular Quay ferry wharves to make them accessible for all customers and cater for future growth. To achieve this, the NSW Government required a comprehensive understanding of the existing infrastructure and conditions at Circular Quay.
There were challenges including GIS data integration, collaboration between different multidisciplinary teams and finally the site location, with Circular Quay being a busy tourist hotspot.
Digital engineering methods were used to bring together a range of different types of survey data, site investigation and geotechnical reports in a single cloud-based model - the Asset Information Model (AIM). The AIM allowed the teams to manage data input and output during and after the project.
New Technologies Case Study: Data Sharing in Infrastructure
The UK National Infrastructure Committee commissioned a significant report from Deloitte in 2017 on New Technologies Case Study: Data Sharing in Infrastructure. A key gap identified by many stakeholders was the absence of an overarching set of principles that provided guidance and clarity on issues such as data ownership, what constitutes data, what might be interpreted as personal and non- personal, ensuring security by design, and so forth. While such a framework cannot ever be considered definitive, a common set of principles applicable across the whole sector (which can be customised) can be used as a starting point for subsequent data sharing, building on the work by industry groups to providing overall guidance.
The principles of the framework could cover areas including:
- Best practice guidance for organisations to carry out an internal audit of their data, classifying different types and identifying data that can be shared, either as open data or with restrictions.
- Best practice guidance for data quality and formatting for different categories of data.
- Approaches to specifying contracts that give appropriate emphasis to data requirements, clarity around.
- responsibilities and liabilities related to data and ensure there is scope for data to be used and re-used.
- Approaches to data anonymization and aggregation so that confidential data may become shareable.
- Steps to deal with grey areas around data ownership, data and IP, personal and non-personal data, etc.
- Appropriate security measures for data sharing in infrastructure, building on the Government’s ’10 steps guidance’ and NIS Directive principles to build awareness and understanding among infrastructure players, setting out explicitly how best practice in cybersecurity can be achieved by infrastructure organisations.
This framework would benefit from leadership by a public body with an invested interest in each industry, which would be complementary to the work carried out by industry-led groups. Inputs should be sought from industry and academia, and facilitated by public bodies such as regulators and NIC.
User Case Study: Digital Engineering reduces commercial risk for the Parramatta Light Rail
Digital Engineering (DE) makes use of processes that enable more productive methods of planning, constructing, operating and maintaining infrastructure assets. This case study focusses on the use of DE to improve the quality of underground utility surveys for the Parramatta Light Rail (PLR) Stage 1 project.
The PLR will connect Westmead to Carlingford via the Parramatta CBD. Experience from previous light rail projects highlighted that a lack of accurate information about underground utilities poses a significant risk to contractors.
As a solution to this, multiple parties were engaged to conduct surveys and gather details about the existing underground utilities. The application of DE was applied to develop a coordinated utilities model that was made available on a GIS system to potential tenderers. This allowed the NSW Government to provide bidding parties with accurate and reliable data.
Standards Case Study: Uniclass 2015
Internationally, Uniclass 2015 is the UK Government’s official construction sector classification system and is part of its Building Information Modelling (BIM) Level 2 resource set.
Support for Uniclass 2015 continues to grow:
- Austroads has independently recommended the adoption of Uniclass 2015 for classification of road assets.
- The Australasian Rail Industry Safety Standards Board (RISSB) is considering the benefits of Uniclass 2015 for nation-wide adoption
TfNSW is currently working in collaboration with NBS, the custodian of Uniclass 2015, to further develop Uniclass 2015 to meet transport requirements.
