3 Introduction to BIM on Bergen Tram Project Mott MacDonald Ireland delivered worlds First Complete 3D Tramway Design for Construction (2013) in Norway (7.5km Line and 40 tram Depot) 2014 FIATECH Celebration of Engineering & Technology Innovation (CETI) Award Winning Design Automation Large Project Design Management Office, staff used to overseas projects Light Rail; Dublin Luas Tramway , Bergen Tramway 2012-Ongoing Other Power & Civils Projects; Bahamas, Abu Dhabi, Mauritania Empower, Roads 334 individual 3D models, with 1,913 individual controlled transmittals, over 3 years. Collaboration between MM offices with Project Engineering, BIM and Technical expertise

4 - 16,000 Employees 180 Offices Worldwide 1.2bn turn-over

5 Kingdom of Norway Total Land Area of 385,000 square km. (84,000 Square km) Population 5,109,059 (6,378,000m) 4 th highest per capita income in the world Member of the European Economic Area Largest per capita producer of oil outside Middle East Wage differences - between lowest and highest Norway

6 BERGEN 2 nd biggest city in Norway Population of 277,000 in the city 412,000 in the Greater Bergen Region Principal city in Hordaland County Hordaland Fylkeskommune is the administrative authority for the county Bergen Kommune City Council Tram is funded through local and national government BERGEN 2250mm rainfall pa (Dublin 730mm) Bergen

7 - THE PROJECT: BERGEN TRAM STAGE 3 AND DEPOT 7.5 km of double track Depot with 3 Buildings 7 Stops 10 bridge structures Retaining Walls Cut & Cover Tunnels 6 tunnels 3.8km Multi-storey carpark Roads, public lighting and signalling Utilities Landscaping Power HV & LV Control Systems

8 BERGEN TRAM KEY DATES Stage 1 (2010) Stage 2 (2013) Stage 3 (2016) Flesland Terminal (2017) Depot (2015) Bybanen key Dates

9 Project Team Collaboration Project Team Collaboration Dublin : Civils / Elec & Rail Systems Cork : Roads, Bridges, Retaining Structures London: Tunnels Budapest : Tunnels Bristol : Geotechnical Prague & Brno : Bridges Bergen : Client Interface PiMS ProjectWise Key Dates 2012 Q1,2 : Bergen Line Setup 2012 Q3 : Bergen Depot Setup 2013 Q1 : Add Project Stage Controls External Collaboration Client 3D Workshops Contractors / Local Authorities Time - Quarters

10 BIM Models Generated Use of BIM Modelling Railways

12 BIM for Large Infrastructure projects - video

13 BIM for Large Infrastructure projects - Important Decisions

14 Important Decisions - Software Selection - Features - Interoperability - Staff capability - Hardware & network requirements - System Speed and Latency - Client/Contractor compatibility

15 Example of Software Selection (Interoperability) 1.Engineering/ Modelling 2. Coordination 3.Deliverables AECOsim Bentley MX Ben. Rebar MicroStation DGN DWG PDF DWG Civil 3D NWD Navisworks NWD Revit Cads RC P: NovaPoint

16 Important Decisions - Selecting and Staffing Design Teams - Work packaging - Train/Hire - Timing of Workload - Design team must buy in to 3D delivery - New Roles (Information Officer)

17 - Important Decisions - Level of Development & Detail

18 Important Decisions - 3D or 2D - Depends on design team capabilities - Project requirements - Programme - Budget

19 Useful Findings

20 Useful Findings: Client Benefits of BIM Shared Understanding Stakeholder Visualisation Model for Stakeholder Reputation...MMD has produced a fantastic 3d model which runs through a very complex terrain. From what i have seen on other projects, this is maybe the most complete and advanced infrastructure model you can find today... Construction Progress...A lot of the things MMD has done in this project with 3d models will probably set a benchmark for how things, are presented in 3d in future infrastructure projects in Norway.

21 Useful Findings QA & Workflow Tools

22 Useful Findings - BIM Management should allow changes to plan if beneficial: - Change to Navisworks in 2013

23 Useful Findings - Virtual walkthrough for Safety Assessments

24 Useful Findings 3D in Design Worked Well Design appreciation across disciplines Access to wider design team Sharing live information Design development with stakeholders Geospatial coordination Can Improve Planning: sequencing and interdependence of assumptions and deliverables Cut back on 2D drawings more Reduce number of software platforms (if possible) 100% model led designs Improved awareness on construction across teams

25 Useful Findings - Construction Information 3D Model - Setting Out

26 Useful Findings - Construction Information 3D Model - Setting Out

27 3D Model - Setting Out

28 3D Model - Setting Out Information Directly from 3D Model Appreciation of Construction Interfaces Maintain Project Controls

29 3D Model - Setting Out

30 Useful Findings working with the models Risks / Collaboration Need a shared understanding and accepted allocation of risk

31 Useful Findings - Challenges Time for changes, updates Timing of activities Resource management

32 Useful Findings Summary Positive Experience, many parties welcomed this new approach and took advantage of the project. Time savings on construction stage compared to traditional projects Needs buy in from all parties Using BIM and a CDE makes the larger projects more manageable, and can deliver project savings in time and quality.
