BIM lessons from the UK's Crossrail project

By intouch * posted 29-03-2016 15:38, the belief that bim technology is unaffordable is an “urban myth”, according to the head of technical information for europe’s largest construction project..

The AU $27.5 billion Crossrail project – London’s first new underground railway line in more than 30 years – will increase central London rail capacity by 10% when it is completed in 2019. Tunnelling started in 2012, and construction is now 75% complete, with the line due to open to passengers in 2018. The project has been hailed as a major driver of BIM processes, with managing company Crossrail Ltd aiming to make Crossrail the first major infrastructure project to fully realise the BIM lifestyle concept. Crossrail’s Malcolm Taylor – who was recently invited to Australia by technology provider Bentley to speak about BIM – says the sheer size of the undertaking meant working in the construction industry’s traditional silos was going to be impractical. “It was just too big a project to be undertaken by one designer, and we knew we were going to have 25 designers,” Taylor says. “We're talking about soaking up most of the UK design capabilities. So we were going to have a lot of people, and we had to figure out how that was going to work. “We used a British standard, BS 1192, that we helped develop, which was all about figuring out a way in which multiple parties, multiple organisations could actually operate and work together in a CAD environment. That set the scene for the concept of collaboration in common data.” Since planning began in 2008, about 1 million CAD files have been created, approved and integrated within a centralised, 3D BIM information model. Taylor says he often hears people describe BIM as “a big investment” – however, he argues that is not the case, particularly when viewed from a whole-of-life cost analysis. One of the greatest advantages of working in the BIM environment is that the model becomes a “single source of truth” for the project, which results in reduced errors by ensuring only the most appropriate version of models, drawings and documentation are used. “It may be a little costly and cost you a little bit of time initially,” Taylor says. “But once you're into it and you've adapted and you understand what it means to be working in a coordinated 3D world, the value that you add is so much better. “When people say to me, ‘Yeah, it's a big investment’, normally it’s people who don’t really understand what you actually invest in.” “It’s an intellectual investment in changing your processes of working, investment in changing how you do things. You're still buying computers, you're still buying software, but actually that's a small part of the cost. The difference between something that's going to do BIM-level two or BIM-level naught is minuscule. “People talk about training costs. Again, that's all very small. “That's why it is an urban myth that BIM costs more.” For a project the scale of Crossrail, the savings from using BIM have been mind-boggling. “Instead of having one application for asset information, one application for document management and one application for contract administration, all our contracts are managed through workflows in the same database,” Taylor says. “That saves us up to £10 million a year just in IT costs alone.” The accuracy afforded by using BIM’s 3D models has meant Crossrail has been pushing the boundaries of what is possible. The "Eye of the Needle" is a name that the contractors gave to a place at Tottenham Court Road station where the new tunnel needed to go over an existing Northern line tunnel and at the same time under an escalator tunnel, with less than a metre clearance from each. “The owners of all that infrastructure had to be persuaded that what we were doing was achievable and feasible,” Taylor explains. “It was our information world, really, that did that, and people could see that it would work. “If they had said no to that, we'd have been probably costing the project another £100 million, because we would have had to have gone at least another five to eight meters deeper. So it saves all sorts of costs.”

International BIM Object Standard

In 2015, NATSPEC, the National Building Specification UK (NBS) and Masterspec NZ agreed to work together to create an International BIM Object Standard using the NBS BIM Object Standard as the starting point. In December, an initial draft was sent to a number of industry experts in Australia and New Zealand for review. The second draft, including guidance notes and supporting information, is scheduled to be widely circulated for review and consultation within the Australian, NZ and the UK construction industries in April.  The Standard will consist of a core document that includes all items that represent a common approach, plus individual national appendices to accommodate local needs that are the inevitable product of differences in building and procurement practices, building products and regulatory frameworks.

Bim4rail – crossrail london railway stations, sector: rail & guided transport, services: digital twins,.

Laser scanning of three London Railway Stations to create a BIM, allowing the re-design to take place for new Crossrail plans.

Crossrail Limited, established in 2001, is the company that has been set up to build the new railway that will become known as the Elizabeth line when it opens through central London in 2018. Crossrail is pioneering the use of Building Information Modelling in Europe on a scale that has not been undertaken before. This has directly enabled us to develop innovative engineering design solutions, minimise waste and reduce future costs for maintaining the railway.’ – Crossrail.

In 2014 Severn Partnership were commissioned by Hochtief to undertake laser scan surveys of three London stations. The surveys took 3 weeks; one week per station, capturing up to 500 RGB static scans.

These stations are situated on the proposed Crossrail route & therefore are due to undergo substantial refurbishment.

Project Details

In 2016 many discussions took place between Severn & the design team with regards to the creation of a 3D model of each station. It was important that each model was suitable for each profession in terms of the level of detail and information included. For example, the Architect required LOD4 throughout all platforms capturing changes of surfaces such as drainage routes, concrete & tactile paving.

The model included all visible elements; platform furniture (seating, screens), tracks, sleepers, gantries, canopies, OLE, lighting and topography, as well as the main station buildings internally.

Each model needed to be created to within +/- 10mm. This lead to the decision to create the models within AutoCAD and export to the necessary DGN file format, to then be used within Bentley Microstation. CAD offered flexible modelling, allowing tight tolerances to be met for features such as the OLE. All components were categorised into the required and compliant Network Rail layering system. This was necessary to allow models to be segregated and federated between all stakeholders throughout GRIP design stages.

There are many challenges that come as a consequence from exporting to DGN (commonly loss of data). Our modelling team have processes in place to mitigate these risks. For example using the most up-to-date plug-in software exporting options, carrying out 3D visual checks and ensuring layering and entities are consistent between the two software packages.

The design team have utilised other deliverables such as Seeable Maps and TruViews, which are often agreed to be delivered as a package alongside 3D models. 360 Panoramic Images are taken on site in specified locations. Those images are then embedded within a 2D site plan or 3D model. Seeable Maps increase stakeholder understanding and allow visibility, ultimately reducing the need for on-site inspections. TruViews are a similar application which allow the user to ‘walk-through’ the point cloud. TruViews are hosted online for free, allowing anyone involved within the project to easily view and measure from the point cloud (using the various tools available). These tools have been made especially appropriate for those who have software restrictions.

All Severn Partnership surveyors are appropriately trained for working within the railway environment; with a dedicated HSQE performing site audits and completing necessary documentation.

Crossrail: embracing BIM for construction

As Crossrail’s Tier 1 contractors prepare for major work, Bentley Systems has been brought on board as part of the supply chain to help the £15.9bn project transition into the construction phase.

As any Londoner will tell you travelling on a packed Central line tube in rush hour is not an experience to relish. The capital is crying out for a major new transport link to ease east-west congestion and Crossrail is answering that call.

Crossrail’s world-class metro style service will carry over 200 million passengers per year. With 42km of new tunnels, 37 stations, eight new sub surface stations the scale of the project is huge. With a budget of £15.9bn it is Europe’s biggest construction project. An incredible 14,000 people will be needed by its supply chain at the peak of construction.

BIM beyond design

Managing a project of this size is a major challenge, and Building Information Modelling (BIM) is playing a major role.

“What I’m looking for Crossrail is a single BIM model that connects the start right the way through to the end,” said Crossrail chief executive, Andrew Wolstenholme. “As an industry we’re not very good at this. The as-designed versus the as-built versus the as-maintained tends to be on different platforms.

“[By linking these technology sets up] we have one continuous set of the truth, the right answer, in a single format that we can pass seamlessly through eventually to the operator.”

Crossrail’s integrated project team standardised on software from Bentley Systems from the very beginning. The software is used to contribute to a fully co-ordinated 3D model and the distributed project team is connected across multiple locations by Bentley’s ProjectWise collaboration platform with BS1192, the British standard for collaborative production of information.

With Crosrail now moving into the main construction phase the project is throwing up a whole new set of challenges. From a BIM perspective this includes how to get the various contractors to collaboratively contribute to information modelling and business processes.

To help bring the contractors on board Bentley has been appointed a Crossrail partner for construction enterprise and has become part of the supply chain, a much more integrated function than that of a traditional supplier of software.

In its new role, Bentley has put together some key initiatives to help support Crossrail’s transition into the construction phase. Bentley’s chief executive officer, Greg Bentley, communicated these proposals to Crossrail’s Tier 1 contractors earlier this year at Bentley’s UK headquarters in London.

Mr Bentley explained how Crossrail’s Enterprise License Subscription (ELS) will be broadened to serve its Tier 1 contractors — giving them controlled access to the full portfolio of Bentley software.

Access to the software will be provided through Bentley’s ‘select server’ and each supplier will be given a ‘key’ so usage can be tracked by Crossrail. Mr Bentley said that in some cases Crossrail will provide machines with pre-loaded software.

Mr Bentley was clear that contractors will not have to purchase any software licenses adding that “Crossrail sees the advantage to the project of using that software.”

Access to a standard set of tools is only one challenge, however, as Mr Wolstenholme explained, “BIM is not simply about the application of new software — it’s about a different way of working.

Crossrail facts and figures

• At £15.bn, Crossrail is Europe’s biggest construction project.
• Crossrail services will commence on the central section by 2018.
• Around 200 million passengers will travel on Crossrail each year and it will expand London’s rail network capacity by 10 percent.
• New Crossrail stations are being built at Paddington, Bond Street, Tottenham Court Road, Farringdon, Liverpool Street, Whitechapel, Canary Wharf, Custom House and Woolwich.
• 42km of bored tunnels will weave their way between existing underground lines, sewers, utility tunnels and building foundations at depths of up to 40m.
• Each Crossrail train will be 200 metres long and will accommodate up to 1,500 passengers.
• Up to 24 trains will run per hour between Paddington and Whitechapel during peak times.

“If we are to take advantage of the opportunity BIM offers the programme, and our contractor organisations, we need to collaborate closely with our supply chains to make it happen.”

Crossrail will start by expanding the reach of Bentley’s ProjectWise collaboration platform with BS1192. Tier 1 suppliers will be given access to Crossrail’s ProjectWise environment with caching servers used to solve large file problems.

Supporting the use of Bentley software through the Crossrail construction phase will also require significant investment in training. Bentley will work with Crossrail to create content for classroom workshops, which can be hosted at Bentley’s UK headquarters or locally. The Tier 1 supply chain will also be offered the benefits of Crossrail’s Enterprise License Subscription with Bentley, which includes unlimited learning through virtual classrooms.

New opportunities

An added benefit for Bentley of working with the Crossrail supply chain is the opportunity presented to expand its relationship with many of the industry’s leading contractors.

Mr Bentley explained how Crossrail contractors will be offered Bentley software, specifically ProjectWise, for use on their own projects for collaboration, work sharing and engineering content management. ProjectWise could be run on local servers or put entirely in the cloud, he said.

Mr Bentley confirmed the preferential discount and subscription terms offered to Crossrail would be extended, but the usage would not be tracked by Crossrail.

Bentley is also setting up a new BIM academy at its London headquarters, where it will invite contractors to discover and share ideas on Bentley technology. Technology pods will showcase a variety of new software and hardware including tools for mobile devices such as the iPad, intelligent digital pens, and laser scanning, a technology he sees playing a major role in the Crossrail project.

A legacy for industry

With a clear strategy in place for how to integrate BIM into the supply chain through the delivery phases, the next major challenge for Crossrail will be how to manage the handover to Rail for London.

Mr Wolstenholme sees this as a huge opportunity. “Infrastructure projects of the scale and complexity of Crossrail do not come around very frequently,” he said. “I want to use the Crossrail opportunity to move the whole industry forward in a number of areas which includes the use of BIM through the delivery and lifecycle phases of major projects.

“The real prize for me is to move the industry boundary as to how you manage the assets using digital technology,” he said.

Beyond the legacy of Crossrail itself, Mr Wolstenholme believes the project will become a “legacy of capability” for industry. He sees it playing an important role in the input for High Speed 2 [the new UK high speed rail network] and, in the future, maybe even for Cross Rail 2 and an aviation transport hub in the east of London.

Part of the book series: Management for Professionals ((MANAGPROF))

In the nineteenth century, the Regents Canal company highlighted the important role railways will play in London in future. Crossrail Ltd. was established in the year 2001 to build the new railway line known as the Elizabeth line through central London. The initial budget for the project was set at £154 million. Crossrail Limited is the wholly owned subsidiary of Transport for London (TfL). The company was established as a 50/50 joint venture company between Transport for London and the Department for London. The Crossrail project is currently Europe’s largest infrastructure project in Europe. The new Elizabeth line will be fully integrated with London’s existing transport and will be operated by Transport for London. The Elizabeth line will increase central London capacity by 10% and reduce congestion at many London underground stations. In a span of 3 years, eight giant tunnel boring machines had burrowed below the streets of London to construct the 42 km new rail tunnels. Over 200,000 tunnel segments were used to line the 42 km of tunnels. The final estimated amount of funding for the project amounted to £17.8 billion. The principal risks to which the project is exposed include safety programme delivery, commercial, organizational, stakeholder and financial risks.

BIM for Designing and Construction of Railway Infrastructure: A Comprehensive Guide

12 min read

September 20, 2023

Table of Contents

Building Information Modelling (BIM) is an essential tool for engineers and planners, providing them with a comprehensive 3D model of the entire railway network, including all the intricate components like tracks, stations, bridges and tunnels. BIM enables users to detect conflicts and clashes early during the planning phase, saving valuable time and resources and preventing costs because of delays in construction and revisions. In this blog, we will explore the essential role played by BIM in shaping the current and future railway systems. We will delve into the fascinating world of BIM and its transformative impact on railway infrastructure from the design and planning stages to construction, operation and beyond.

What Is Railway Infrastructure?

Railway infrastructure encompasses a wide array of physical components that collectively form the foundation of a railway system, facilitating the safe, and efficient operation of trains. These include tracks, bridges, tunnels, stations, signals, signage, electrification, rail yards, switches, crossings, fencing, security measures, communication and signalling systems, and maintenance facilities. Rolling stock, including locomotives, passenger cars, and freight wagons, are also essential. The complexity and scale of railway infrastructure can vary significantly based on factors such as the type of railway (e.g., commuter, freight, high-speed) and regional and operational requirements. The continuous maintenance and upgrading of railway infrastructure remain imperative to ensuring rail transportation systems' safety, efficiency, and reliability.

Use Of BIM In Railway Infrastructure

BIM is a versatile tool that has transformed railway infrastructure development. It provides efficiency, precision and sustainability in designing and planning. In this section, we will explore seven key aspects where BIM has transformed the railway infrastructure development contributing to the success of the vital transportation system. 

1. Design and Planning

BIM for railway engineers and planners is used to create a detailed 3D model of the entire railway infrastructure, including tracks, stations, bridges, tunnels, and other components. This visualisation by the 3D model helps in a better understanding of the project's scope and design. BIM software can identify clashes or conflicts in design early in the planning phase. This helps prevent issues that could lead to costly construction delays and revisions.

2. Cost Estimation and Budgeting

BIM for railways can automatically generate quantity takeoffs based on the model, helping project managers estimate costs more accurately. BIM software can visualise cost data, allowing project stakeholders to understand how different design choices impact the budget.

3. Construction Management

BIM for railways can simulate construction phases, helping project managers plan and sequence construction activities more effectively. BIM can be used to allocate resources such as labour and equipment efficiently. BIM can track the actual construction progress against the planned schedule, enabling early identification of delays or issues.

4. Asset Management and Maintenance

BIM for railways can serve as a digital twin of the railway infrastructure. It contains information about all components, materials, and equipment, making it a valuable resource for maintenance teams. BIM can be integrated with sensor data and maintenance schedules to predict when elements might require maintenance or replacement. BIM can be used to optimise railway operations by providing real-time data on track conditions, signalling, and other critical systems.

5. Safety and Risk Assessment

BIM for railways can simulate various scenarios to assess safety risks and develop mitigation strategies. It can aid in emergency planning and evacuation procedures by providing a detailed model of the railway infrastructure.

6. Stakeholder Communication

BIM for railway models can be used to communicate the project's progress and design to stakeholders, regulatory agencies, and the public more effectively. BIM facilitates collaboration among various stakeholders, including designers, engineers, contractors, and operators.

7. Sustainability and Environmental Impact

BIM for railways can be used to optimise the railway's energy consumption by simulating different operational scenarios. It helps assess the environmental impact of the railway project, including factors like noise pollution and carbon emissions.

Benefits Of BIM For Railway Infrastructure

Building information modelling (BIM) offers an extensive approach to building railway infrastructure projects, providing advantages across the whole project lifecycle. BIM for the railway industry allows for improving efficiency by reducing costs, minimising hazards, and supporting sustainability initiatives , from improved design and construction coordination to continuing maintenance and operation.

BIM for railway infrastructure projects is used to enhance design, construction, coordination, and ongoing maintenance, ultimately leading to more efficient, cost-effective, and sustainable rail networks. Here are six case studies highlighting the implementation of BIM in railway infrastructure projects around the world:

Improved Design and Visualisation: A precise and comprehensive visual representation of the entire railway infrastructure is provided by BIM via detailed 3D models. Designers and project stakeholders can better comprehend the project's scope, spot design flaws, and make informed decisions early in the planning phase.

Enhanced Coordination: BIM facilitates coordination among various project stakeholders, including architects, engineers, contractors, and suppliers. Clash detection tools in BIM help identify and resolve design conflicts and coordination issues, reducing errors and rework during construction.

Cost Estimation and Control: BIM enables accurate quantity takeoffs and cost estimations based on the model's components and materials. Project managers can use BIM to track costs throughout the project's lifecycle, helping to stay within budget.

Efficient Construction Management: BIM supports the simulation of construction phases, enabling project managers to optimise construction sequencing and resource allocation. Real-time progress tracking helps identify delays or deviations from the schedule early, allowing for timely adjustments.

Environmental Impact Assessment: BIM can simulate various construction scenarios to assess and mitigate environmental impacts, helping projects meet regulatory requirements. It aids in the design of more sustainable railway infrastructure by optimising energy use and minimising ecological disruption.

Stakeholder Communication: BIM models can be shared with stakeholders, including government agencies, communities, and the public, to provide transparent project updates and address concerns. Effective communication enhances public support and regulatory compliance.

Safety and Risk Assessment: BIM can simulate safety scenarios, helping assess and mitigate risks during construction and operation. Emergency planning and evacuation procedures can be tested using BIM, enhancing safety preparedness. Operational Efficiency: Railway operators can use BIM to monitor and optimise track conditions, signalling systems, and other critical components, ensuring smooth and safe operations. Real-time data from BIM models can improve decision-making and maintenance scheduling.

Crossrail is an example of how urban change has created integrated transport opportunities. This is one of a collection of four case studies covering social, economic and environmental opportunities resulting from urban change in London .

Crossrail Case Study – Transport in London

London has a  comprehensive, integrated travel system. This is a network of transport systems which link to one another to increase the use of public transport to help reduce traffic congestion and CO2 emissions;

London Underground – the new Elizabeth line links central London to the Suburbs, encouraging more people to use public transport.

Oyster Card is a travel payment method that people can use on buses, trains and tubes quickly and efficiently; you can now use a bank card.

Congestion Charging Zone – A £15 daily fee to any vehicle travelling in central London between 7 am and 6 pm, Monday to Friday and 12-6 pm on weekends.  This encourages more people to use public transport.

Bike sharing scheme – Self-hire bikes are available in many public places in London for as little as free for 30 mins. This has encouraged many people to cycle rather than drive, reducing traffic congestion.

Why is there a need for improved transport in London?

London’s transport system is well-integrated but struggles to keep up with the increasing number of passengers due to population growth and more work opportunities. Public transportation is preferred as most Londoners cannot rely on driving due to limited parking and traffic congestion. In 2014, approximately 75 million people used underground trains and buses in London per week, which continues to rise yearly.

Transport improvements in London

The demand for public transportation is predicted to increase by 60 per cent by 2050, making long-term planning and investment essential.

Launched in 2022, Crossrail is a recently built rail system that spans from east to west London and connects Shenfield and Abbey Wood in the east with Reading and Heathrow in the west. Upon completion, the rail system, renamed the Elizabeth line, runs underground through the city centre. It is expected to decrease travel times and bolster overall passenger capacity.

Plans for Crossrail 2 are already in motion, with a projected timeline of 2030. This second project would involve constructing a north-south rail system across London that is similar in scope and design to the first.

What could the impacts of Crossrail be for London?

Crossrail, one of the largest infrastructure projects in London’s history, is expected to deliver numerous advantages, including:

• Significantly reducing journey times, such as the trip from Liverpool Street to Heathrow, which will decrease from over an hour to just 35 minutes.
• Raising the number of rail passenger journeys in London by 200 million annually, resulting in a ten per cent increase.
• Enabling an extra 1.5 million individuals to commute to work in central London within a 45-minute timeframe. • Improving the transportation system in London by providing more connections with the Underground network.
• Boosting property values by approximately 25% in areas around stations along the Crossrail path.
• Stimulating further regeneration throughout London, providing access to thousands of additional employment opportunities.
• Enhancing accessibility for disabled individuals to new stations. There are no stairs from the platform to the street level.
