REMOTE SENSING & MAPPING
__rendered_path__6__rendered_path__9
The RWS - CKAS Joint Venture has done numerous
__rendered_path__7
projects across Africa, from 100 000 Ha to 30 Ha,
__rendered_path__10
some of them repeated bi-annually for monitoring
__rendered_path__11
and quantity purposes.
Quantities, As-Built Data, Contours and Sections can
easily be extracted from the data.
Typical absolute Lidar accuracies are 3-7cm even in
heavily vegetated terrain.
High resolution digital orthophoto mosaics enhance
the data, ‘a picture says a thousand words’. We often
deliver images with 7 sq cm pixels, this is 4 times
industry standard.
We are now able to achieve
by using
2 sq cm pixels

SUPERVISION & SETTING OUT
__rendered_path__4__rendered_path__7Image_31_0
RWS was fortunate enough to be involved
__rendered_path__5__rendered_path__8
with the FIFA World Cup 2010 and ensured
__rendered_path__9
that all the external cladding on the Moses
Image_27_0Image_28_0__rendered_path__15
Mabhida Stadium (Durban) fitted perfectly.
Image_30_0
No mean feat considering there were 5
different contractors involved and that the
base of the stadium is roughly circular and its
Image_29_0
top, oval.
RWS has handled many earthworks projects
from major dams to thousands of km’s of
roads. This included QA, design, volumes and
__rendered_path__1__rendered_path__29
setting out.

INDUSTRIAL SURVEY
Image_37_0Image_38_0
This is a spin off of Construction and
Image_39_0
Topographic Surveys. Experience
ranges from petro-chemical and
aluminum rolling plants to crane rails
__rendered_path__1__rendered_path__13
and architectural cladding.

MINE SURVEYS

FROM EXPLORATION
__rendered_path__7__rendered_path__10Image_46_0
TO MINING
__rendered_path__8
RWS assists mining companies
__rendered_path__11
from exploration right through
__rendered_path__12
to mining operations. Most of
__rendered_path__14
our experience has been in
Image_43_0Image_47_0
Open Cast where work includes
Image_48_0
measuring pits, stock piles,
waste dumps and dams.
Geological exploration involves
either measuring bore holes and
providing surface models or
setting up systems to enable the
geologist to survey the bore
holes themselves.
Another area of expertise is
geospatial planning and site
selection , with limited under
__rendered_path__1__rendered_path__35
ground experience.

ANNUAL SURVEYS
Image_54_0__rendered_path__6Image_55_0
Annual surveys are carried out in
accordance with DME regulations to
determine rate of rise, storm capacity,
freeboard, etc. Cross sectioning of the
piezo-meter lines is also undertaken for
stability analysis.

TAILING DAMS
__rendered_path__9__rendered_path__12
TAILINGS PROJECTS
__rendered_path__10
RWS has been involved with numerous tailings
__rendered_path__13
dams associated with platinum, diamond, gold
__rendered_path__14
and manganese mines across Africa.
Some projects involve identifying potential
sites and surveying them, followed by
modelling potential dams for feasibility
studies, others are the setting out the starter
walls and infrastructure for the construction of
__rendered_path__1Image_52_0__rendered_path__30
new dams.

RWS has surveyed hundreds of thousands of Ha’s
__rendered_path__12__rendered_path__15
using total stations, GPS, Laser Range Finders and
__rendered_path__13
Lidar. The deliverable is usually a Digital Terrain Model
__rendered_path__16
(DTM) also known as a Digital Elevation Model (DEM)
__rendered_path__17
as well as CAD drawings and 3D contours.

CONTROL

Behind the scenes a control
network generally needs to be
implemented to ensure that
the data is correctly
__rendered_path__1__rendered_path__24
positioned.

APPROPRIATE EQUIPMENT
Different environments and project
sizes require different technologies.
GPS performs well in the open but can
be augmented with Laser Range
Finders in heavily vegetated sites.
RWS has experience ranging from
deserts to jungles, sea level to 4500m

agreeing quantities, managing the quality
control of the layer works thickness and
level, calculating various scenarios to

DESIGN & QUANTIFICATION
__rendered_path__16Image_113_0
Digital terrain models (DTMs) are used to
__rendered_path__17__rendered_path__20
depict existing topography, additional
__rendered_path__18__rendered_path__21
design elements, such as platforms or
__rendered_path__22
roads, can be integrated into the project
Image_115_0
to balance the cut and fill as well as
determine volumes.
Potential tailings dams can be modelled in
3D to calculated stage capacities and
starter wall volumes thus optimising the
__rendered_path__1__rendered_path__23Image_114_0__rendered_path__26
design thereby reducing costs.
