Industry is changing from documents to models

But Why and How?

A highly precise virtual reality model is being created

in parallel with the design of a Norwegian road, to

help avoid conflicts in both design and construction.

(World Highways 7 January 2008)

Case Study: RV 150 Ring 3, Ulven – Sinsen Owner: Road Department, Contractor : Veidekke

Average cost per change/conflict has

been calculated to be about

$ 9600 (Norwegian Road Authority)

Part 1: VDC model was not used About 250 out of 600 changes were caused by

design conflict between domains

Additional cost of $ 2.4 mill. (+4,6%)

Part 2: VDC model was used “There has been almost no design

change/conflict on this parcel, E22”, Petter

Bakke, Veidekke

Potential cost savings $ 2.4 mill.

Case Study: 31774 Gjønnes station Owner: KTP AS, Contractor: Veidekke

Total 350 conflicts was found

Half of them had not been

detected without a VDC model

Based on Norwegian Road

Authority estimate potential cost

savings have been $ 1.7 mill.

VDC Potential in Construction

Typical construction additional change

orders are about 20% of construction costs

By using VDC about 75% of change orders

can be avoided

Potentially 5-15% savings

Almost 0 changes or waiting on site

because of design errors

VDC may increase design costs but:

Better design quality, error free designs

Less documents, more digital data

Understanding and communication increases

More time to study alternative better solutions

Affect costs and changes in in earlier phase

Less risks, more fluent construction

Clearly positive ROI, very good investment

Norwegian Contractor Comments

“The 3D models we get for all domains, makes our

working day easier and more efficient. There has

been almost no design change/conflict on this

parcel, E22”

Petter Bakke, Veidekke

“In practise, there are no longer any

change/conflict in the design models we get for

each domain. We use the models for multiple

purpose: Stake out, communication with

construction workers to plan todays work etc.

We love working this way!”

Erik Hval Olsen, Veidekke

“Continuity in production, for all our man and

machine AND doing everything just once, is the

two most important issues for a cost effective

construction.

The use of collaboration models on the

Marienborg project, did that we actually had

almost zero stop at site, caused by errors in

design (like collision between domains). We could

produce continuously.”

Bård-Olav Aune, SKANSKA

Case Study: Zoo Interchange Pilot Owner: Wisconsin Department of Transportation, USA

Input data DGN, DWG, IFC (Utilities, Civil3D, Revit)

LandXML (InRoads, Civil3D)

Modeling Parametric tools allows automatic utilities

modeling from line data

Direct links to input data allows automatic

model updates when design changes

Results Cost effective GIS data modeling in 1 day

Immediate updates directly from Civil3D

Design system independent via open standards

Opportunity: 5% savings from 1.7B$ estimated

construction cost would be 85M$!

Model view with easy navigation makes it easy to get overview of the project and go rapidly into

details. Models can be visualized using color coding or by attaching realistic materials to imported

model elements.

5D simulation tool allows attaching a schedule and cost information into model

parts. Supports MS Project. Schedule is linked to clash detection.

Value based clash detection finds most important design clashes easier and

faster than traditional clash methods.

Collaboration is integrated into the model. With collaboration users can attach

comments to model or manage model specific tasks. These topics can be viewed

with a thumbnail list or as an Excel like table with sorting and filtering tools. Topics

are sunchronized between users via VDC Collaboration Server.

Topics is the center for

collaboration. Topics have

name, description and

attributes.

Attributes are used to classify

topics for example by priority,

responsible, deadline,

discipline.

Topics can have multiple

viewpoints attached which

are saved to collaboration

server for users to browse

without model.

Under topic there can be

additional comments which

form a discussion thread

around the topic.
