COMIT/Fiatech Conference 2015, Hallam, London Ray Dudding, BIM and Automated Design, Atkins and Alex Heward, Engineering Excellence Group , Laing O’Rourke The Digitally Enabling Electrification project Applying the latest information management, survey and digital modelling techniques to the railway electrification lifecycle. It is a partnership between Laing O’Rourke, Atkins, DHP11 and Imperial College set up to align with the UK Government BIM strategy. The project is demonstrating real world construction efficiencies brought about by the management of information through digital engineering. It is grant funded by the Rail Safety and Standards Board (RSSB) and Innovate UK under Future Railways. A key aim is to develop an open data format to allow easy transfer of data between parties. By examining and redefining the information flows between Designers, Surveyor, Constructor, Manufacturer and Asset owner the project aims to minimise on site errors and rework.

3. Challenge: to create efficiencies across the
whole supply chain through digital technology
The project supports :
• The UK Government’s BIM Strategy
• Enabling the Digital Railway

4. Why Digitally Enable?
UK electrification:
£3 billion committed
over 10 years
Resource constrained:
• Timescales tight
• Engineers in short supply
Remit:
How can digital technology help?

(If Possible)

5. Scale of the problem - for every project:
Thousands of structures at
unique locations, individually:
• Designed
• Procured
• Assembled
• Constructed
• Commissioned
• Maintained

7. Why the problem isn’t already solved?
Traditional Methods:
• Massive quantity of design
documents in each project
– circa 1.4Million
• Information spread and repeated
• Potential for error
• Resulting in rework and delays
• Still hand over Paper & PDF

14. • Solve a real world problem
• Involve leading providers
• Prove technology in the field
• Deployable on projects

15. • Precise positioning of piles is
difficult
• Over 1 in 10 are out of
tolerance
• Difficult to measure variance
• Impact on design integrity
• Results in major difficulties

Survey Data Acquisition

16. Survey Data Acquisition –
Assess the state of the art
Market leaders in survey technologies
• Point cloud
• Photogrammetry
• LIDAR
• Traditional surveying technologies
The means of capture:
• Drones
• Road rail vehicles
• Trained surveyors
• Trackside personnel
• Satellite imagery

17. Technology trial on a real railway:
Network Rail Test Track - Tuxford
1. Overhead line foundation piles
in cess
2. Each supplier – surveyed piles
3. Erected different types of
structures
4. Suppliers surveyed
structures

18. The criteria we are assessing:
1. Track Access requirements
2. Limitations of weather conditions –
low light, rain, bright sunlight etc.
3. Time taken to survey
4. Skill level of staff needed to
capture data
5. Cost of survey
6. Time taken to turnaround of data
into usable model
7. Skill level of staff needed to
process data
8. Accuracy of final model
9. Usability of the final model

20. Immediate benefit - When it goes right….
Foundation location within tolerance
Equipment Precision - millimetre accuracy
• Assemblies preconfigured off site
• Minimise adjustment on site
Reduce time on site
Very expensive possession time
• Saving up to 15 minutes per assembly
• Potently £10’s of millions a major scheme

21. When it goes wrong… 3 possible results:
Compelling
Image Here
1. Within equipment design
tolerances
Pre-adjust equipment to new
position
2. Different equipment needed to
retain designed wire position
Order and pre-adjust new
equipment to new design
3. Not possible to retain designed
wire position
Redesign whole area to
accommodate actual structure
location

22. Reduces the chances of this happening…

23. The project has demonstrated:
Augmented Reality
in electrification
projects
New surveying
technologies and
capture techniques
The ability to
modify design
in ‘real time’
The potential for reducing
cost, timescales, disruption
and improving safety
UK Government
BIM strategy
compliant workflow
Advanced BIM
Modelling
through lifecycle
The resolution of
issues with foundation
location and alignment

24. • To make digital technology a viable
and cost saving solution for
Electrification
• Generate open standards so this
new data driven system a fair
market to enter
Less adjustment and hammers on site
Summary
More precision in a safer working
environment for our workforce

25. When the results are in…
Dissemination Day at
The National Railway Museum
York in January 2016
