Digital construction - the road towards BIM.
Agenda• Digital Construction in The Danish Road Directorate
• Storstøms bridge
2.
Working method
Traditional tender
3d design is flattened in to 2d drawings in the tender documents. Surveyors uses many resources on markings. The field supervisors keep track of construction process’.
Digital construction
Data saved in one digital model. The contractor can use models for planning and construction. Navigation is based on the model combined with GPS-coordinates. The field supervisors can access model data and do their job in the field.

PreparationThe Danish Road Directorate has worked with an internal project for “Digital Construction”. The Danish Road Directorate
Digital processThe road model is the center of information. Current versions of data is stored here and there are access for all project members.
Different kinds of extractions can be made from the model.

Dicsipline models are registrered in the database-table MAPS.
TechnologyAll discipline models are saved in one location.
Dicsipline models can be accessed through a number of different platforms and applications such as:
• MicroStation
• Bentley Navigator
• GIS4Mobile (iPad app)
• WWW.
• Etc…
Registrations in the field made by field suporvisors in GIS4Mobile can be accessed in our CAD-programs.

Why?• Reuse of information
• Better design material
• Coordination between disciplines
• Clash detection
• Significantly reduction of drawings in tender documents
• Save time during construction and optimize machine time
• Enable digital calculations for the contractor
• Better design material to reduce downtime for the contractors machinery
BIM is the next level• BIM is:
• Building
• Information
• Model
• 4D time
• 5D price
ObjectPrice Time-consuming for instalation”I am an electric light bulb”

The Storstøms brigde and BIM
Storstrøms bridge Old bridge will be replaced by a new bridge
Old bridge would not be able to bear the weight of the trains in the future
Storstrøms bridgeBudget 4,2 bil. dkk kr.
Two tracks for highspeed trains for 200 km/h
Two lanes for cars for 80 km/h
Bidirectional bicycle path
ICT-requirements for the Storstrøms bridge• ICT = Information and
Communications Technology
• A great chance for BIM way of thinking
• BIM in operation and maintenance
• 4D simulation
BIMRequirements for a very detailed 3D model of the bridge
Requirements for a database to O&M
Our dream when it comes to O&M• Physical inspection is
ekstensive
• Automotion with drones could help a lot
• Photo recognition Automatic rapport generation
