Bridge concepts Perspective BIM
Floating bridge – side anchored or end anchored Multi-span suspension brdge Submerged floating tube bridge
5
Bjørnafjorden Area Perspective on BIM
Planning of roads, tunnels and bridges in the Bjørnafjorden area Replacing two ferries with bridges Reduced travel time north- south 1h.10min. New travel time north-south 50min. Approx cost 35Mrd NOK Traffic up to 20000/day 20 years after start service period.

Bjørnafjorden bridge challenge
Perspective on BIM Bjørnafjorden bridge challenge Bjørnafjorden bridge challenge 5km wide fjord, one-span bridge solutions not possible. 550m deep fjord, tunnel solution not feasible. Concept development initiatives established. Extremely large structures to be investigated and built. Approx tonnes construction steel in bridge girder and pontoons. Challenge: How to secure the predictable project execution and service time?
7
Bjørnafjorden bridge goals
Perspective on BIM Bjørnafjorden bridge goals NPRA is the contract owner and responsible for budget obligations on behalf of the norwegian society. We wish to reduce risks: Related to budget and compensation. Related to purchasing of material, quality and quantity. Related to progress. Related to quality documentation for engineered components and constructed components. Related to service period activities (100 years).
8
Perspective on BIM Digital logistics
The Bjørnafjorden bridge project need a seamless solution for digital logistics: Through engineering phase Through construction phase Through service period (100 years)

Bjørnafjorden Live Center
Perspective on BIM Bjørnafjorden Live Center A Live Center shall provide: Any view into the 3D-model and development status. Interactive and dynamic harvesting possibilities. Automatic and realtime KPI-presentations. Compensation acceptance related to BIM status definitions and development. Service period operation and maintenance planning tool and documentation database. How to establish the Live Center utilising the digital approach that BIM offer?
10
Strategic issues in NPRA:
Perspective on BIM Strategic issues in NPRA: Facilitate future transport infrastructure Road administration through digitalisation Safer road users, improvement Increase sustainable road administration and reduce greenhouse gas emmissions Strenghten NPRA’s implementation capacity
11
BIM – the concept of full BIM implementation?
Drawings 3d model contains all data from concept, engineering, building to operations and maintenance Documents Process codes 3d model Logistics Build phases Materials Operation and maintenance Object types Perspective on BIM
12
Use of BIM in a project? BIM implementation
Establish a BIM culture that runs through the entire project organization – important! Have to assure that all the information is stored and dynamic an all phases of the project. Collaboration between project management, ICT (IKT), project engineers, contractors and operation and maintenance personell. Objective: Seamless integration of data from start to end Perspective on BIM
13
Project management plan
BIM implementation Project management plan Decide on an objective, e.g full BIM implementation Define roles, scope, time and resources. Evaluate competance within the organisation. Establish communication flow – engineers, contractors and maintenance system and software requirements. Risk assessment – use of BIM for quality assurance, progress and compensation. Example: NPRA is the owner, build a bridge over Bjørnafjorden, in- house engineering with aid from consultants, decide on engineering programs, object oriented software, develop a operating system for maintenance………….. Perspective on BIM
14
BIM manual BIM implementation
A BIM manual is a guiding document for project implementation: Coordinate system. Use of existing data (terrain, roads, water and sewage). Object names (projectcode manual). File and folder structure. Model owners – roles and responsibility. Engineering tools – softwares allowed in project. Manuals/instructions – model build-up, splitting of models. Routines for control of models. Viewer tools – both for 2D, 3D og data. Perspective on BIM
15
How to store data in a 3d model?
BIM implementation How to store data in a 3d model? Layer based or object oriented information? A database connected to the model. Standards for data storage in 3d model? Currently no standards for bridges, roads and terrain. Use the .ifc format? 2 file system, 3d file and data file? Possible solution? «Information model»? Perspective on BIM
16
Introducing the «Information model» and object oriented engineering
BIM implementation Introducing the «Information model» and object oriented engineering Handbooks from the NPRA describes the hierachy of a bridge, naming all major components (objects) and also to a lesser extent their corresponding attributes. Bridge Superstructure Abutments Plate Beam Box Foundation Wall Perspective on BIM
17
«Information model» BIM implementation
An «Information model» is a hierachy of object types and their relations – object names and attributes. Bridge Objects Attributes Pillar Road Tower Material Concrete B45 Steel B55 …….. ……... … …….. Perspective on BIM

Collaboration between Dutch and Norwegian road administrations
Prototype from the NPRA Collaboration between Dutch and Norwegian road administrations Example shows XML data inside an Excel sheet. Standardized object names and attributes based on «Information model». Reminder: There are no standards for files concerning bridges, roads and terrain. Building engineers have standards and the .ifc file format. Perspective on BIM
20
Live Center BIM implementation
A Live Center importa data directly from 3d model and the XML file Works as: a viewer a database a logistics center a dynamic gatherer of information a collision controller an interactive interface – generating reports, tables, graphs and change logs. Perspective on BIM
21
Example of a Live Center
BIM implementation Example of a Live Center All info available – both 3d model and associated data. Click on items in viewer to retrieve data or search in database for information. Plan procurement – logistics. Perspective on BIM
22
Challenges How to promote BIM to your managment?
How to illustrate risk reducing effects? Benefits of BIM in general? What is in it for me? Perspective on BIM
