ARCHAEOLOGICAL SURVEY OF ONSHORE WIND FARM SITE REVEALS UNRECORDED NEOLITHIC FEATURES
Fugro recently completed an airborne light detection and ranging (LiDAR) survey of five onshore wind farm
sites in the county of Caithness, Scotland for RES and Baillie Windfarm Ltd. The detailed mapping exercise
highlighted the benefits of the accurate terrain data derived from LiDAR.
Undertaken for AOC Archaeology Ltd, the survey was part
of a major archaeological landscape survey in Caithness,
an area rich in ancient sites. It is one of the most detailed
landscape mapping exercises ever undertaken in Scotland
and was designed to record the setting of the Baillie Hill
wind farm prior to construction.
“Our recent airborne LiDAR assignment at Caithness presented
lots of challenges,” says Chris Boreland, Business Development
Manager of Northern Ireland-based Fugro-BKS, a full-service
geospatial and aerial acquisition company. “The weather was
particularly poor at four of the sites and the fifth was adjacent to
the Dounreay nuclear power station, necessitating special flight Piper aircraft used for the airborne LiDAR survey
permissions to fly over the site.”
Seeing Through Vegetation
Chris explains the reason behind an increase in the use of
airborne LiDAR surveys for wind farm developments: “A major
benefit of LiDAR mapping is the rapid collection of a high
accuracy 3D terrain model of the survey area. In the case
of Fugro’s FLI-MAP® system, a further benefit is the ability
to measure ground height information underneath dense
vegetation.” The FLI-MAP® system effectively ‘sees through’
this vegetation, even when very dense, and can define the
ground surface, rocks, mounds and tracks that are otherwise
obscured and impossible to map by other means. This is done
FLI-MAP ® system installed in the aircraft
by distinguishing the first reflected light returns, which define the
tops of trees, bushes, grass and other vegetation from the final
return, which represents the ground surface. The setting, at Cnoc Freiceadain, is of one of the most important
clusters of Neolithic funerary monuments in Caithness and
the survey offers a unique view of the sites in their landscape
context. Processing the data brought to light a large number of
unrecorded features, greatly increasing the number of known hut
circles in the area and redefining the extent of medieval and later
settlement and agriculture. The dataset therefore constitutes an
invaluable research tool and an unparalleled means of preserving
the landscape of 21st century Caithness for future reference.

Project developers and consultants are increasing their use
of geospatial information, such as the terrain data derived
from LiDAR, in a variety of ways. Prior to construction it can
be used for wind speed analysis, vegetation cover, roughness
and clearance, view shed analysis, slope stability analysis,
access road design and for environmental and archaeological
assessments. This information is an invaluable aid for turbine
location selection and volumetric calculations for crane pad
construction, as well as providing corridor mapping for network
grid connection and substation location selection.

OVER 1,000 KILOMETRES OF IRISH RAIL NETWORK SURVEYED IN JUST SEVEN DAYS
In a major contract for Iarnród Éireann (Irish Rail), Fugro recently completed the collection of railway
trackbed data using train-mounted ground-penetrating radar (GPR). The work, which covers almost half
of the Irish Rail network, was awarded after a competitive tender process.

A TALE OF TWO SYSTEMS
FUGRO DEMONSTRATES LEADERSHIP IN LiDAR WITH FRENCH COASTAL SURVEYS
Working with France’s hydrographic agency, Fugro is conducting surveys of the Finistère and
Provence-Alpes-Côte d’Azur (PACA) regions of France. This important project is part of the Litto3D® survey
programme, which is to become the core of the country’s future integrated coastal management projects.
As the only company in the world to manufacture, support

FROM SMALL DUTCH ENGINEERING COMPANY TO GLOBAL SERVICE PROVIDER!
The ability to generate early solutions for new challenges is one of the cornerstones of
Fugro’s success. Since its formation in 1962, its innovative approach to developing new
expertise and technology has led Fugro to a market-leading position as a service provider.
Mr Klaas Wester’s presentation
Technical ingenuity and determination have been decisive
factors during the past 50 years. Fugro’s development of electric
cone penetration testing equipment in the 1960s represented
a breakthrough in offshore site investigation. More recent
innovations include highly accurate offshore satellite positioning
systems, the optimisation of deepwater pipeline design with the
Smart Pipe tool and the new WaveWalker 1 walking jack-up rig
which will improve utilisation rates as it is less susceptible to the
impact of adverse sea conditions.
