An Open Framework for Infrastructure Digital Twins
Open Source and Collaborative Models Build Trust, Reduce Costs, and Create Value
What would you say if you could wave a magic wand and eliminate all the time and effort that you and your organization spend on transforming data, integrating data, and aggregating data? What if you could spend your time generating insights and helping your teams make decisions that can save you money and reduce your risk?
When I began my career, our industry was going through the digital transformation of computer-aided design (CAD), which was taking what we were doing on paper and moving that to the computer. The next disruption was when the industry moved from CAD to building information modeling (BIM). Now, our industry is advancing beyond BIM with the emergence of infrastructure digital twins — so-called iTwins. These iTwins bring in the missing dimensions of context – the physical characteristics of where the asset is on the planet — and the dimension of time, as well as other types of data such as Internet of Things (IoT) and operational data. We've gone from document-centric workflows to model-centric workflows, and now in the era of the digitally built environment, the next logical step is the move to data-centric workflows.
Networking with ET, IT and OT
Enterprises are collectively becoming data-driven, and the organizations that are going to succeed are going to be those that can convert data into actionable information and maximize its value over the asset lifecycle. Infrastructure data can benefit from network effects, which means that the more people that use the data, and have access to the data, and contribute to the data, the more valuable the data becomes. Therefore, openness and connectedness are going to be the enablers for maximizing the value of data and causing those network effects to thrive in the infrastructure ecosystem at large.
The objective is to federate data coming from engineering technology (ET), information technology (IT), and operational technology (OT) and bring it together where it can be viewed through a single pane of glass. One of the primary challenges in orchestrating this data aggregation has been the time and effort involved in transforming and aligning proprietary and incompatible data formats. What is needed to solve this problem is an open platform that can extract all these different types of information and integrate them together seamlessly.
Openness of Digital Twins
In a paper titled “The Gemini Principles,” the Centre for Digital Built Britain (CDBB) identifies “openness” as the central principle for achieving “effective information management of the built environment.” Their conclusion is that open source and collaborative models build trust, reduce costs, and create value better than any other approach.
For a digital twin platform to be “open,” we at Bentley think that it must meet three primary criteria. First, it must be vendor neutral with regard to the applications being used. The system needs to be able to extract all this information and make it available in an open context.
Second, the system must be open to where the files are located. It should not be expected that all the data that you're working with is going to be in one homogenous, structured space or monolithic database. Connectors can be built to go find the data, where the data lives.
Third, the system must be open in terms of the semantics of the data, with the ability to take data in its native format and open it into an open standard that you can query, interrogate, and integrate the information.
”Open source and collaborative models build trust, reduce costs, and create value.“
In June 2019, we released version 1.0 of the iModel.js platform on GitHub. This is an open source platform for creating, visualizing, and analyzing infrastructure digital twins. It is open, flexible and built for the cloud, web and mobile world we live in today. It establishes an open platform for you and your supply chain to build upon, to connect, and to be able to derive value from infrastructure digital twins across all your workflows. The system is written using modern cloud and web technologies and is available for building your own solutions to visualize and connect with the rest of the digital world.
Open Source for Complex Infrastructure Projects
Bentley is willing to make its most innovative and new technology available as open source, because we have a fundamental belief that — in the long-run — an open system will be the most successful in creating a thriving digital twin ecosystem for infrastructure.
Complex infrastructure projects will benefit from a thriving, open and interconnected ecosystem of data. Data should flow freely — in and out of infrastructure digital twins, and it should be transparent and easily understandable by users. It should also be easy to develop workflows that access and take advantage of the data within digital twins.
The potential for infrastructure digital twins is truly unlimited, and openness will be a prerequisite for delivering digital twins that will advance our industry beyond BIM — helping us derive greater insights during design and construction and ultimately deliver more sustainable and resilient infrastructure during operations. For digital twins, openness wins.
