Sign positioning
Final positioning of signs
along a road is normally carried
out in-situ. Sign positioning
in this project was
however set using the VR
model. All signs were
entered with correct text
and size and the positioning
was determined based on
visibility requirements and
relevant guidelines for
signs. The VR model provides
a good basis for evaluating
sign positioning.
Planning permission processing
The VR model is in addition
used for providing information
on the project in planning
permission applications.
Still pictures are
extracted from the model
and enclosed with the application.
VR MODEL AVAILABLE TO ThE ENTIRE PRO-
JECT ORGANISATION
Each time the VR model is updated, it is copied to
the project hotel. This is then available to all project
participants including planning, execution and
development personnel.
Use of the model at the construction site helps
understand and plan execution of road construction.
VR MODEL AS FDV DOCUMENTATION
The VR model can provide a useful supplement to
the traditional ‘As Built’ documentation.
Visualisation of the infrastructure which is concealed
under road surfaces, behind tunnel walls etc.
will make work easier for those who in the future
are looking for information on the installation.
What form the VR model for highway 44 should be
delivered with other FDV documentation for the
construction site has not been not clarified with The
Norwegian Public Roads Administration.

PROJECT hOTEL
As companies in the project
group, contractors and the developer
are geographically separated,
a project hotel based on the
Internet is used for exchanging
reports, drawings and surveying
data. This is structured so there
is an area for delivery for
approval and an area for
approved working documentation.
Contractors and planning
personnel in addition have their
own area for internal exchange of
planning data, surveying data
etc.
The drawings are in dwf format
and are plotted and distributed
directly to the construction site.
EVALUATION
This it the first road project in
Norway with such extensive use
of 3D models throughout the planning and construction
phase. There is little doubt that this type
of aid is necessary if increasing requirements for
deliveries and detailed working document are to be
met. Greater knowledge and overview of project
solutions will ensure better execution and reduce
the extent of errors. The model increases understanding
of the construction site and improves the
documentation used in the evaluation of alternatives,
solution decisions and the planning of different
work operations.
The model is also an important tool in satisfying the
requirements for external information.
We have come a long way in this project. However,
several improvements can be implemented in the
next project. Not least reducing the threshold for
use of the model. It should be very natural to
access the 3D model when problems linked to the
project are to be discussed by the developer and
contractor. The model should be used extensively
and actively at the construction site as an aid in the
planning of work operations and as a supplement
for working drawings.
Development is moving towards planning directly in
3D models, as we see in other sectors such as
building and offshore. We have not had the same
level of development within road construction. One
of the reasons for this is the length of the construction
area and continuous changes in the interface
towards neighbouring areas, terrain, ground
conditions etc.
