Bentley Systems held the Rail Virtual Press Briefing entitled “Going Digital in Rail and Advancing BIM through Digital Twins” this week, featuring presentations from Bentley executives, Steve Cockerell, Industry Marketing Director, Rail and Transit, Eduardo Lazzarotto, Director of Project Management, and Teresa Elliott, Industry Marketing Direction, Digital Cities.
Key users spoke on their projects: Peter Ruff, BIM manager, Skanska, STRABAG Joint Venture and Robert Alberola, BIM Information Manager for TYPSA UK – SCS Railways and Baptiste Frioux, Senior Consultant – Flow and Mobility, AREP.  Canterbury Vent Shaft – Skanska, Costain, STRABAG (SCS) With increased urbanization, globally 55% of the world population lives in cities, and city occupancy should grow to 68% over next 30 years, noted Cockerell. “With an urgent need to respond to climate change, our future needs to be sustainable. Look at emissions per passenger per km traveled. Air travel is the largest producer of emissions. Transit travel is 28 times more polluting than rail. Rail is the key to a more sustainable future.” Making a case for rail also includes consideration of the Covid-19 pandemic. “I hope this challenge can be converted into an opportunity,” said Cockerell. “And can be a driver for going digital. Recent digital transformation involving 80% of people working from home will be part of people’s new normal.” Collaboration tools are more important now than ever before to Bentley Systems, with the demand most likely accelerating. McKinsey & Company advocates increased digitalization and simulation in use to re-plan and optimize project schedules, among other things, in their report, “How Construction Can Emerge Stronger from Corona Virus.” In the short term:
In the long term:

 Ruislip Portal – Skanska, Costain, STRABAG (SCS) Britain’s New Railway has been going digital and simultaneously working on HS2 for about 4 years with ARUP, Costain, Skanska and HS2, said Peter Ruff. “The project should be delivered right the first time. The goal is to design, construct and maintain the railway digitally using both graphics and non-graphical information in a Common Data Environment providing real time access to reliable and accurate data.” The teams are using BIM services – 3D, 4D, 5D +6D; Information Management Services – CDE, Asset information; Geographic Information Systems Services – web maps, spatial analysis; Data Services – analytics, structures, databases, schema; Technology Services – digital survey, VR, AR, mobile. There are many complicated interfaces and existing infrastructures to be considered in the project such as Network Rail, TFL, London Underground and a lot of utilities. “On previous projects the teams may have interacted on one or two workstreams,” said Huff. “We can now enhance processes of other teams. This includes members from the community engagement team in understanding works and quality, and is made possible by the high level of data.” Used in the production line are: ArcGIS, management workspace/schema inside ProjectWise, iModel Transformer and FME, Synchro, CostOS, SQL database and PowerBI to consume it, a wide range of mobile apps, connecting machines, including OpenBuildings and OpenRail. “Digital data has allowed us to plan in sequence, has allowed the team to optimize sequencing in Synchro, and caches in time can be identified early,” said Huff. “Digital twins link assets with costs and time to form a project controls perspective.” HS2 puts great emphasis on reducing carbon on the project and SQL stores digital tools and a wide range of applications for the data. The creation of a robust set of processes and tools for the digital manufacturing line, allow the teams to use digital information in many processes. Data extracted is now analyzed in a sophisticated way by using advanced reporting and data analytics. SCS uses imodel information to derive estimates for the work, a key feature in the assessment of carbon, said Robert Alberola. HS2 uses the 5D+ approach as a fundamental feature that allows rapid analysis and creation of a carbon footprint generated by design. They optimized construction from the carbon point of view, as well as cost, and were able to model 3D cost. The project led the industry due to speed, efficiency and accuracy, all made possible by going digital. “The information helps us build the project, and going digital speeds up delivery of data for quality inspections,” said Alberola. “We have more consistent outputs, and reality meshes and point clouds show where teams are constructed out to tolerance.” Bentley’s digital permitting process increased the understanding of utilities onsite and safety. The use of virtual reality and artificial intelligence in a more interactive setting enhanced the team’s knowledge. Return on investment:
“Learning from past experiences. we knew our approach had to be scalable,” said Alberola. “We knew upscaling was a must. We tested and benchmarked solutions we have put in place, and needed to capture hearts and minds. It had to be a datacentric approach.” “The use of intelligent iModels has allowed us to remove many drawings,” said Alberola. “The 5D approach used fewer resources in time. 4D allows for 30% reduction in plan time, intelligent iModels allowed us to remove 80% drawings. SCS has three million pounds savings with digital.” Eduardo Lazzarotto, Director of Project Management said that the lifecycle moves from project delivery through handover of assets in operations. “We can’t cover every asset. Our focus is on stations and platforms. Going digital increases reliability and optimizes performance on day one but ensuring assets remain fit for purpose throughout their operational lifecycle.” Lazzarotto used the example of London’s Bond Street Station, and going through the conceptual design and using simulation so they could quickly test the design- how people will behave and move inside that station, and also how to adapt the station for the future of disruption. “All the technological disruptions we’ve been seeing over last couple of years, not just Covid-19. We can use that simulation to understand shops, barriers and other operational plans to run that station.” “We can accelerate design of that station, using GenerativeDesign, and the information can be taken to the operation of that station, and social distancing can be applied in the early stages of design.” Lazzarotto said that all the data gathered in the concept and design phase can be implemented in the whole timeline of the project and through operations of the asset. “Many are operating as we are delivering parts of the project. After it goes into operation, all that information we’ve generated during the design and construction phase, can be converted into a digital twin, it can be used to simulate the digital future, lighting, access and egress, evacuation, social distancing, energy efficiency, aisle devices in that space, etc. We can sue that data to create what if scenarios of the space, so we can deliver more of the asset over time.” Digital stations become resilient stations, so they are ready for different types of disruption, and they are quickly able to respond to that situation, and they go through to a recover space. Those models can be used to reopen some of those stations and railways. Baptiste Frioux, Senior Consultant – Flow and Mobility, AREP spoke on Railway – Going on a Digital Journey. The goal with the Paris St. Lazare Train Station was to simulate and analyze foot traffic on infrastructure assets. Teams needed to accurately test designs and operational or commercial plans to enhance footfall, wayfinding, crowd management and safety and security strategies. With LEGION software, they were able to optimize the use of space to improve safety, efficiency and revenue. Their objectives were to work closely with the architects to develop the most efficient design to accommodate all amenities (services and shopping facilities) without reducing pedestrian comfort. The project was complex in that there were multiple actors and financiers: Shopping center owner’s objective is to create a maximum of commercial space Transport operator’s objective is to improve traveler connection by reducing journey time. During the construction stages – Objectives:
Execution: Team work with the architects and the construction firms to propose alternatives such as:
“It would save us a lot of time to integrate pedestrian into one model,” said Baptiste. “We’re integrating pedestrian integration into StationDesigner to make sure it’s available from the earliest stages of design.” Teresa Elliott, Industry Marketing Director, Digital Cities, spoke on City-scale Digital Twins.  Winner Innovation in Reality Modeling: City of Helsinki – Helsinki 3D+ The project for the City of Helsinki is the Kalasatama digital twin that communicates the project with stakeholders and citizens, explores future and current parts of the work. “People are taken out to see the progress and they can provide comments in that digital twin environment. Helsinki 3D Plus won the TechFest competition. Helsinki had early projects on wind and noise analysis, and worked with wind simulation and other energy analysis projects.” To create the digital twin, they use city scale in Context Capture, streaming online and to mobile devices. ContextCapture provides much clearer communication in the early planning stages. “There is a difference between rail and transit,” said Elliott. “Organizations must immerse their teams in decision making and run different analytics to provide different outcomes.” But for the future, looking at carbon footprint and efficiency, “Make sure rail remains smartest, fastest, means of moving goods and people between countries.” Tags: 3D, 3D cities, AEC, architects, architecture, Bentley Systems, BIM, building design, building information modeling, CAD, Cloud, collaboration, construction, covid-19, design, digital twin, engineering, engineers, generative design, GIS, infrastructure, laser scanning, mobile, point clouds, reality capture, visualization, Year In Infrastructure 2019 Categories: 2D, 3D, AEC, AECCafe, apps, architecture, Bentley Systems, Bentley Year In Infrastructure 2019, BIM, building information modeling, Cloud, collaboration, construction, construction project management, drones, engineering, field, field solutions, file sharing, geospatial, GIS, greenhouse gas emissions, IES, IFC, infrastructure, integrated project delivery, Internet of Things, IoT, mobile, point clouds, project management, reality capture, rendering, simulation, site planning, sustainable design, traffic simulation, video, virtual reality, visualization, wearable devices, YII 2019 |
