Understand When UAV is Right for a Project

We understand which projects, or, parts of projects are suitable
and cost effective to survey with a UAV. The UAV must be con-
sidered as another tool, and only used where suitable from H&S,
costs effectiveness, etc, allow.

Deliverables can include:

• 3D Point cloud
• Rectified High Definition Orthophotos
• Digital Surface / Terrain Model
• 3D CAD Model
• Contour lines

UAV Building Surveys

UAV Building Surveys

UAVs can be extremely useful for certain building
survey tasks, particularly at externally high areas
that are not visible safely from ny other point.

UAV Flight Planning

The remote pilots UAV flight path will be predetermined in the
planning stage and flown in a systematic route around the asset
to give 100% confidence that all surfaces are covered and to
ensure statutory requirements for safe flying are met.

Processed Dense Point Cloud

Using the hi-resolution images captured from the UAV to create
dense 3D point cloud which are used to complete measure-
ments of gradients, heights, distances and volumetric calcula-
tions.

CAD Drawings

CAD drawings can be produced rom the scale point cloud which
includes spot heights, roof foot print, roof furniture and pitch an-
gles—all to aid space planning of additional roof plant, access
route discussions, etc.

Condition Report

Warner Surveys can provide condition reports of the asset which
will be highlighted in the report which can aid preventative
maintenance.

UAV Volumetric Surveys

UAV Volumetric Surveys

Volumetric stockpile measurement surveys have become ex-
tremely efficient and accurate in recent years using UAVs.
At WS we have embraced this and teamed up with a cloud-
based secure platform so you can visualise and analyse site
data with tools everyone can use at any time in any location.
All repeated site surveys are laid over one another to create a
visual timeline to monitor changes and create downloadable
reports.

Cloud Based Portal
Secure cloud based portal providing 24hr access to the pro-
cessed data sets. Downloads available include: Orthophoto,
Digital Surface Model, 3D Point Cloud , 3D Model
With a cloud based system there is no need to install software
locally to PC, and the portal is accessible on tablets and mobile
phones for ‘on the move’ viewing.

3D Volume Cut and Fill
As simple as clicking the mouse pointer around the stock pile
the portal will instantly work out the cut and fill volumes of the
selected area. A visible 3D ‘uplift’ is generated for the user to
visual confirm that the correct area has been selected.
The base ‘underside’ survey (often interpolated by the surveyor,
and often not ‘flat’) is crucial for accurate volumes. Our 40 year
survey heritage ensures we establish the most robust interpreta-
tion possible.

Stockpile Cross Section
The portal can generate cross sections, highlighting the peaks
and troughs. These can be draped over the model for visualisa-
tion purposes.
Cross sections can be compared to the interpolated base survey
as shown.

UAV Project Progression Monitoring

UAV Progression Monitoring

Periodic Monitoring or ‘Snapshots in Time’ can be extremely
beneficial on a construction project to record progress against
schedule and / or to aid or confirm sub-contractor payments, as
well as for marketing or neighbourhood relations.

UAV photos, videos, maps and models provide an aerial over-
view of your entire project. By investing a couple of hours flying
a UAV at each milestone (weekly / fortnightly, etc), you will have
an archive of data to help your team work more efficiently, make
more informed decisions, potentially save money and communi-
cate with ease.

Previous clients also use the footage to enhance and show the
health and safety risks in the site induction.

4K Aerial Video & Photos

Let your project stand out from the crowd - capture previously
unreachable angles from the air and produce branded video.
Photos of progress of, e.g. brickwork lifts can be recorded for
payment purposes.

Stockpile Volumes

Volumes of stockpiles of loose materials can be calculated.

Health and Safety

Data can be accessed remotely by staff in distant locations and
potential H&S risks can be identified - e.g. Scaffold issues

Cloud Based Portal

Data can be accessed via secure 24hr cloud based portal.
Downloads available include: Rectified Orthophotos, Digital Sur-
face Model, 3D Point Cloud , 3D Model
