NVF 2. sep 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. Digital Road model Design Construction Tender model Supervision Road model Traditional tender Supervision Design 2d cad Drawing files Construction Tender documents

Preparation The Danish Road Directorate has worked with an internal project for “Digital Construction”. The Danish Road Directorate

Digital process The 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. DATA-MODELDATA-MODEL Drawings Reports Visualization Road Drainage Terrain Equipment Soil drilling Setting out data Bridge Rainwater basins

Function created with Microstation Customize – ”VD Theme” Dicsipline models are registrered in the database-table MAPS.

Technology All 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. iPad application – GIS4Mobile Bentley Navigator Registrations of conditions made with GIS4Mobile by field supervisors Registrations made with GIS4Mobile accessed in Bentley Navigator

Policy ICT = Information and Communications Technology Delivery specifications Document describing requirements for suppliers of digital deliveries. Links to the model standard Model standard Homepage describing the content and appearance of model data. Home of information about data for all project participants. ICT – communication specification Document describing Common basis for all communication. Links to the model standard ICT – Technical CAD- specification Document describing how the data should be structured. Links to the model standard Delivery specifications Model standard ICT – communication specification ICT – Technical CAD-specification

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 Object Price Time-consuming for instalation ”I am an electric light bulb” Object Price pr running meter Time-consuming for instalation ”I am a waterpipe”

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 bridge Budget 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

BIM Requirements 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
