What is

A set of integrated processes …

… relying on a model built with highly described elements

(Building Information Model)Railways (Building Infrastructure Model)

4

What BIM is not…

- It is not a model containing only pictures or 3D volume descriptions without attributes

-It is not a model containing non parametered bulky objects, unable to have their size or their position adjusted because of the lack of any true content, which leads to tiring and unefficient file loadings

5

What BIM is not…

-It is not a model enabling modifications within a view which would not be automatically updated in all other views

-It is not a set of softwares which will replacer our tools, for design, planning and Computer-aided Maintenance

- It is not the miracle tool that will automatically manage our projects

6

Benefits from BIM : Collaboration

Efforts and impacts of modifications are shifted earlier during the conception phases

Benefits from BIM : Knowledge Continuity

Without BIM : knowledge fracture at each phase transition

With BIM : Continuity of information

8

Benefits from BIM : Documentation

BIM brings the ability to generate and handle all the usual 2D documents, precise and with coordinates available within all views.Should modifications be performed within the BIM model, these documents will automatically be updated in BIM model.

9

Benefits from BIM : Coordination / Detection of issues

Coordination between the various contributors through the BIM platform, enabling automatic detection of interfering objects included in the project, prior to the real works.

10

Benefits from BIM : Implementation of 4D and 5D

With BIM model, planning of works can be simulated, tested, adjusted, then launched. Cost impact of each and every change is immediately estimated and available

[Planning control, Cost control]

11

Benefits from BIM : Asset Management

Once the Build phase done, the digital mock-up that contains all the smart data is converted into a reference database,

very useful for Infrastructure’s operation - Maintenance - Rejuvenation.

12

Benefits from BIM : Further ahead, enhanced reality

Data from BIM model can be confronted to field reality, Before - During - After Build phase

BIM : What is requiredManagement involvement, for deciding, initiating and supporting The changes required for the success of BIM deployment:

• Strategy & Organisation• Methods & Tools• HR contributions (evolution in jobs, new jobs,…)• Quick Investments in technological equipments (workstations, software licences)

Need for a specific team, PMO-like:

• Market analysis• Driving of the Change process• Assistance to users (methods & Tools)• Collect feedback from experience of former BIM projects

Everyone on board to succeed with the radical changes

14

Why BIM is useful

BIM fully contributes to the success of the ‘I&P 2020’ organisational project SNCF Engineering Division

Better knowledge of the assets, for safety but not only

Change and improve management of our studies and projects. A radical change towards Digital Engineering, for a global better service to customer.

Increase of productivity and reduction of complete cost of infrastructure and equipments (20-30 %). Control of the budget is key for the future.

Tighter cooperation, staff career development and lower level of stress, to have people accept the changes

BIM : Project Charles de Gaulle Express, Where SNCF is up to?

- Identify added values of BIM for Overhead Catenary and Power activities

- Inform employees and obtain their commitment (with coaching)

-Feed global brainstorming concerning the changes concerning the Engineering expertises

- build a prototype of a 3D digital model with BIM functionalities

Goals

Target definition

Target definition

• Expertise expectations • Interface issues • Definition of elemental bricks for each expertise and process to be set up

• Input data• Scanned data• Retro-engineering• Geometrical Modelling

BIM : ERTMS Project, Where is SNCF up to ?

Process launched in the ERTMS context and mock-ups initiated

- Bring a Feedback from experience on the various benefits fom BIM

- Demonstrate utility of BIM in terms of cooperation

- Demontrate integration of infrastructure’s modifications

- Estimate the required modifations (interoperability,…)

in railwayProject contextSetting up :

-A dedicated server for processing and storage of the -3D data and Drone (400 To)

- A dedicated team for the data processing and its control

- A light web service application to enable easy sharing of the data

Example of an unexpected (but possible) BIM application at ‘System’ level :

A Head-up Display for the train drivers,

connected to Information Technology,

complementary to all the existing equipment on the dashboard,

taking advantage of Infrastructure Model data,

to provide all useful information for a better driving, better service

The load curve of charge is shifted to the left

Low workload cases have increased

One of the initial study’s conclusions : reduction of the workload for driver

High workload cases have diminished

Focus on the influence of HUD on the perception of their workload, by the drivers themselves
