Novapoint Civil Construction

Sandvika east surface section: Early version of the model
BACKGROUND
The development of a 3D model was initially not a
part of the agreement with The Norwegian
National Rail Administration. In a separate meeting
with The Norwegian National Rail
Administration it was discussed whether to use
this type of technology and working methodology
in the work. We and The Norwegian National Rail
Administration both saw the potential and the
many opportunities it could offer and it was therefore
agreed to initially establish models for both
the surface sections (Lysaker west and Sandvika east).
The start point of this work was the setting up of
models of the substructure. This work should also
be started immediately so that the basic model
was ready by the time the first track plan version
was completed.
TEChNOLOGY AND CONTENTS
The work started immediately. It was decided that
Novapoint Virtual Map should be used as a tool.
This is a quick and efficient tool for updating the
model as planning work progresses and is simple
for all parties to use. Procedures for working with
the model for the different professional areas were
set up, so that we could include all constructions
directly into the model and generate an updated
model in a short space of time.
The existing situation for both surface sections
was set up using existing maps and associated
orthophotos. It was also agreed to incorporate
planned elements continuously, such as:
• Track geometry
• All constructions (portals, tunnels, walls etc)
• Fences/railings
• Vegetation planting plans
• Road geometry and emergency service areas
• Railway engineering installations such as KL
masts and cable ducts
• Rig areas
The model was initially used at internal working
meetings with The Norwegian National Rail

Sandvika east surface section: Demo construction model
Administration as a basis for discussions and to
quality control solutions. It was in addition used to
extract still pictures from agreed view points to
present the different solutions.
The model was used more and more actively and
updated continuously as the planning work progressed.
We, working with The Norwegian National
Rail Administration, saw several opportunities to
expand the model geographically, its content and
not least into more areas of application.
The work was expanded, at the request of the
Norwegian National Rail Administration, to include:
• The option to drive through the entire section.
Entire tunnel sections should therefore be
modelled including all details such as niches,
fans, suspended masts, emergency tele
phones, block telephones and other installations
in the tunnel.
• Establish routes for different types of train
• Construction models for all rig areas including
transverse tunnels with loading stations
• New Lysaker station. Basis was received from
Cowi, who had set up a model of the station
previously
• All main signals, repeat signals and dwarf
signals for the stations
• All markers
• DVD film for use in information meetings with
affected neighbours
I.e. Everything which is planned and visible along
the entire section in 3D.
AREAS OF USAGE AND ExPERIENCE
How was the model used in the project group and
by the client?
As mentioned previously, the model was used in
all types of meetings and was on average shown
once a week in different forums (planning meetings,
land owner meetings, information meetings,
presentations, professional groups etc). This tool
was also perfect for:
