2 Client Stakeholders Supplier Designers Contractors

3 What is the Project? C510 contract

4 Liverpool Street Station

5 Whitechapel Station

6 What was the problem? Delayed Access Programme Methodology

7 What was the problem? Delayed Access Delayed access to top of the escalator barrels as the other contracts were still constructing their works Programme Methodology

8 What was the problem? Delayed Access Programme Mitigation was required in order to win back time on the programme and take the escalator barrels off of the critical path Methodology

9 What was the problem? Delayed Access Programme Methodology Traditionally excavation is downhill with plant accessing from the top utilising winches to support the plant. Uphill excavation puts the working team beneath the exposed tunnel face with a standard excavator located on the tunnel invert

10 What was the problem? Traditional uphill tunnelling

11 What was the solution? manufacturing suspended systems for the mining and rail industries in Germany in the field of suspended mechanised platforms and machines.

12 300 custom made units

13 300 custom made units

14 What was the solution? BBMV integrated the Lasershell TM principle to continue to provide maximum safety potential: 300 custom made units

15 Suspension 300 custom made units Innovation

16 Lasershell TM Suspension 300 custom made units Innovation

17 Lasershell TM Suspension 300 custom made units Innovation

18 Lasershell TM Suspension 30 incline 300 custom made units Innovation

19 Lasershell TM Suspension 30 incline 300 custom made units Innovation Excavation & spraying arm

20 Lasershell TM Suspension 30 incline 300 custom made units Innovation Excavation & spraying arm Separate operators cab

21 Lasershell TM Suspension 30 incline 300 custom made units Innovation Excavation & spraying arm Separate operators cab Bespoke walkway alongside

22 The innovation Suspended excavator remains away from the invert keeping the operator safe

23 The innovation Suspension system cast and fixed as the tunnel advances.

24 The innovation Suspension system cast and fixed as the tunnel advances.

25 The innovation Suspension system cast and fixed as the tunnel advances.

26 The innovation Uphill excavator with walkway alongside.

27 The innovation Uphill excavator with walkway alongside.

28 The innovation An innovative solution that enables the operator and engineer to be elevated away from the tunnel invert in a safe position.

29 The benefits Removing the escalators from the projects critical path

30 The benefits Removing the escalators from the projects critical path Released key interfaces between several contractors

31 The benefits Removing the escalators from the projects critical path Released key interfaces between several contractors Allowing BBMV to work almost completely independently from others, without interference and/or constraint.

32 The benefits 6 months earlier completion (ES1) Reduced the time frame that BBMV required in the station shafts and helped with the optimisation of the overall Crossrail programme. Significant Cost Savings 13.5m on the general time related expenses of the project from the tender option ES2 1.5m from the ES1 value engineering of stand-by time

33 The Future Safe system of work for constructing incline tunnels from the bottom up Inclined excavations carried out from the confines of the serviced tunnels without disturbing the connecting shaft or tunnel Independently construct to open shafts and live/operating station, 24/7 Electric powered reducing the emissions from normal tunnel excavators and spraying robots Avoiding suspending works due to breakthroughs or temporary works
