Novapoint Civil Construction

planning work was started. The first working drawings
were delivered on approximately 1 December
2006, one month after start up. Project completion
is 15 December 2007. 7 I.e. only one year from the
detail planning start to project completion.
ThE PROJECT
The road project
includes approximately
4 km of new
highway 44, approximately
2 km of local
roads and a similar
length of footpaths.
A rock tunnel, three
bridges and four
underpasses are
included in the project.
There is in addition
a significant
amount of municipal
line re-routing.
The rock tunnel has
been stipulated to Normal profile surface section
protect the valuable
recreational area by Kleppelunden. The road would
probably otherwise have been planned as a surface
road on the west side of ridge if this condition had
not been included.
The road section has three crossings which are
designed as roundabouts.
Dimensioning traffic 20 years
after opening is estimated to
be 18,000 AADT. At this traffic
volume level, the road should
be designed as a four lane
road with central reservation.
The tunnel should, in accordance
with standards, have
two shafts with two lanes in
each direction. The Norwegian
Public Roads Administration
has approved an exemption from road and tunnel
standards and set the road standard to a wide two
lane road with central barrier.
Tunnel cross section T10.5 is selected to achieve a
1.5 m separation zone in the centre of the tunnel.
Barriers are not acceptable in a tunnel, as this
would hinder evacuation in the event of an accident.
PLANNING
The project is planned digitally using the different
professional modules in Novapoint. Organisation of
8
drawings and folder structure follows The
Norwegian Public Roads Administration’s PROF
standard. A digital terrain model is set up based on
digital maps and supplementary surveying data
along the entire route. The surveying was carried
out by Skanska Survey.
The OPS project E39
Klett - Bårdshaug in
the county of Sør-
Trøndelag and the
tender phase for
OPS E18 Grimstad -
Kristiansand has
allowed ViaNova to
develop a strong
cooperation with
Skanska. This cooperation
continues in
this project.
Cooperation has
contributed to the
development of
both planning
methodology and
software. A modern road construction site with GPS
controlled machines and equipment needs much
more comprehensive surveying data than was previously
the norm. Road models have been supplied
for all roads, both road surfaces and formations.
Surveying data has in addition been prepared in kof
format for all lines, manholes,
lighting foundations, sign foundations,
cable trenches etc.
Surveying data in the form of
goals from a reference line has as
far as possible been avoided.
A work procedure where the
solutions are verified in a 3D
model is required if satisfactory
cross-profession co-ordination
and survey data control is to be
achieved. Controls carried out in
the ‘old fashioned’ way in 2D using associated
height calculations can no longer be accepted, as
the solution also must be cross-profession checked
in x, y, z. A cross profession VR model was therefore
set up immediately after start, using Novapoint
Virtual Map. All professional areas plan digitally and
deliver data to the VR model co-ordinator, who
updates this continuously. The solutions are
checked/evaluated in the VR model in cross-profession
meetings and changes are agreed. Revised
solutions are prepared based on the review which is
updated and then reviewed again in the VR model.
This process continues until the ‘right’ solution is
