The London Bridge Station Redevelopment was a six-year programme with 11 ‘Entry Into Service’ (EIS) stages.
At the original outset of the project, there was no requirement to provide a BIM Level 1 As-Built 3D model but as the project progressed, the benefits of using the BIM features of Level 2 became apparent. One of these features is the Smart Asset Registers.
With the accumulation of six years of work, the project had amassed:
- 14,000+ Red Line mark-ups
- 4000+ As-built drawings
- 6000+ maintainable assets
- 16000+ non-maintainable fabric assets
- 2000 plus assurance files
- 100 operation and maintenance manuals
Traditionally this material is stored by the National Records Group and incorporated into a health and safety file but retrieval of information can take up to four weeks.
Using BIM level 2 meant scanned 3D models of the station areas with maintainable assets could be tagged with physical QR code asset IDs and digitally tagged on the Smart Asset Register. Assets were captured with photos, videos, photogrammetry and LIDAR laser scanning to create a digital model which could be accessed online. The cloud-based platform allowed all the assurance amassed over the Project to be hosted on the platform so all information available at a click of a button. This pilot scheme was used to be compatible with OPAS so the new system could be used for asset faulting and generate Planned Preventative Maintenance records/programmes. With the assets QR-coded, any time maintenance is carried out the operative can use the new platform to download the report, complete update on what was maintained/replaced and load back as completed PPM.
This has also been beneficial for new staff who may not know what an asset is called, using the Smart Asset Management System, each room has been scanned and the maintainable assets digitally tagged. This means the user can see the asset they are looking for click on it and the information page displays the manufacture information, contact details and the O&M.
Operational staff now can access asset information from mobile devices, tablets and desktop computers instantly and from wherever they are.
Key benefits and recommendations
Utilising and implementing BIM has large client benefits and provides a visual close out for areas.
- It mitigates the loss of staff turnover as knowledge is stored in a single place accessible to all rather than in a single user’s files.
- Projects can provide EIS assurance from the BIM model itself.
- Areas can be captured on the BIM model linking Form 5 assurance information such as LUX levels, PAVA audio levels, floor slip resistance, fire systems and CCTV monitoring.
- Information is transferable.
- Storage space is unlimited.
- Systems meet all requirements standards.
