Novapoint Civil Construction

The location of the new runway means that planes
approaching must change their di-rection approximately
2.5 kilometers from the runway. To show this
an approach level has been added to the 3D model.
The level starts at the runway and then moves upward
with a 2 % tilt. The level is see-through in order to
keep the terrain beneath visible – see figure 2. At the
same time, the approach level shows places that hit
the terrain. In these cases parts of the terrain must be
removed.
At this point another level, the barrier level, has to be
added to the 3D model. This level also starts by the
runway and moves from this point upwards to all sides
with a 1:7 7 tilt – see figure below. The amounts that lie
above the barrier level is also shown in the figure
below.
Approach and barrier level
In Novapoint it is possible to calculate the excavation
amount. The approach level re-sults in a 3.5 mio. m3
excavation while the barrier level results in an over 92
mio. m3 excavation. These amounts are so huge that

an alternative – higher – location of the runway must
be examined.
A flight that shows the model without the two levels
has been made to show the 3D model - see the figures
at the bottom.
Different possibilities and cost estimations can be tested
out when ”laying” the run-way in a 3D model. This
gives a greater certainty about the final projekt when
it comes to quality, time frame and economy.
Earlier on, a preliminary examination consisted of
many longitudal profiles and cross sections. This was
slow and time consuming work. When using a 3D tool
you save valuable time and at the same time your data
is ready calculate masses.
LANDSVERK has used the 3D model to show and
explain the preliminary examina-tions. This has been
the best possible way to present their results to politicians
and other stakeholders. A 3D model makes it far
easier to explain non-specialists how the project needs
to be adapted to the challenging terrain.
LANDSVERK are currently examining three other locations
that are possible candi-dates for accommodating
an airport: Glyvursnes på Streymoy, Søltuvik på
Sandoi og Skorhæddin på Eysturoy.
LANDSVERK also performs seabed examinations that,
among other things, are used in connection with the
expansion of the Faeroese harbors. In such a case
Novapoint Virtual Map can be used to control and visualize
depth sounding that are made with such accuracy
that you can see ship wrecks and etc.
