One of the hurdles faced by surveying companies is their abilities to deal with the diverse
surveying engineering field and office systems to efficiently deliver their end products in timely
manner. Integrated surveying technology focuses on field surveying data collection systems,
field software, and office software and provide common interface to connect, collect,
transfer, and process data from various field surveying systems in one homogeneous dataset
and in one common project file.
When integrated surveying technology is applied in real world applications, it provides survey
teams and customers with increased productivity and ensures the quality of the survey
data. Therefore, integrated surveying functionality is one of our most determining factors
when making decisions about surveying system acquisitions. Benefits of integrated surveying
technology include:
› Surveyors can efficiently collect and process survey data from various surveying systems
(GNSS receivers, total stations, laser scanners, etc.) with single controller and field software.
Therefore, surveyors have only to learn one field software application making them more
productive more quickly. In addition, the survey data from various field survey systems can
be combined and adjusted in one single file to efficiently establish homogeneous quality
control.
› GNSS control establishment techniques can be combined with total station survey without
the need for extensive traversing which saves time on the job site.
› Surveyors have more flexibility when performing topographic surveys by selecting the most
appropriate survey tool (GNSS or conventional) can be used depending on the work site
conditions.
Surveyors have more flexibility when performing stakeout, particularly on large construction
sites, where obstructions can often interrupt the use of GNSS or total station techniques.
Since integrated surveying technologies are complementary, a surveyor can use the most
appropriate tool to complete a survey using the same data collector on single job file. This
saves time and minimizes errors.
Our field data collection systems, field and office software are fully integrated to ensure we
do the job right the first time and provide our survey team with extended functionality for

TOPOGRAPHIC MAPPING
SERVICES
Topographic Mapping Surveys are carried out to document existing project site
conditions for various purposes such as urban and regional planning, project
design, road and utilities route design, site preparation and grading, quantity and
volume calculation. Topographic Survey typically depicts the configuration of the
ground surface details in addition to site planimetric details. Surface details are then
represented on topographic maps of various sizes, scales and formats depending
on the intended use of the maps.
Topographic data collection can be achieved using traditional survey total station
systems or satellite based positioning systems. The amount of details, accuracy, site
conditions, and project schedule constraints often determine the type of survey
systems used. Both techniques (GNSS RTK or Conventional Total Stations) almost
provide identical output and therefore can
be used interchangeably.
At Twozan Surveys we realize and fully
understand the importance of topographic
data we deliver to our clients which is a
vital input data into the project design and
planning phases. High quality topographic
data in terms of accuracy and completeness
is guaranteed via faultless and well defined
process of clearly identifying project
objectives, professionally supervised field
survey and mapping procedures, and more
importantly, well established quality control and assurance processes throughout
the entire project. All our deliverables are painstakingly tested and checked in
accordance with highest professional standards.
Twozan Surveys has completed numerous topographic mapping projects for various
types of engineering and planning purposes. Our list of featured projects presented
in this profile shows some samples of our previous works of topographic mapping.

CONSTRUCTION LAYOUT AND
STAKING SERVICES
Construction Layout and Staking Surveys are carried out to demark and flag the location (position)
and elevation of construction elements on the ground based on approved IFC design plans and
relative project coordinate system. Such elements include but not limited to foundations, axis lines,
concrete slabs, utility lines, ditches, drainage channels, embankments, dikes, grades, road horizontal
and vertical alignments, manholes, pipelines, culverts, street furniture, or any other design structure.
Construction layout and staking surveys can be carried out using conventional survey equipment
(theodolites, total station, and levels) or Real Time Kinematic (RTK) GNSS systems either combined
or interchangeably. Various levels of accuracies can be specified and achieved depending on
the type and significance of the construction feature. Based on the specified accuracy and site
conditions, our specialist project team will select the type of field survey systems that will deliver the
required accuracy.

COMPLETE SURVEYING SERVICES SOLUTION
FOR RABIGH INDEPENDENT POWER PLANT
Constructions Projects involve significant investments and commitment of human and financial
resources. It also involves the use of highly expensive heavy equipment which is hired or committed
to the project at very costly rates. Therefore, we carefully select and train our construction layout
survey teams to deliver the most reliable survey services for our construction clients. Our excellent
record of successfully completed construction survey projects proves that we have the know-how,
experience, qualified team, cutting-edge technology, and professional approach that will meet
and exceed your expectations.
Every project requires a number of reference
points (monuments) which are surveyed in order
to define their accurate position coordinates
and elevations relevant to a common project
coordinate system. A common coordinate
system is vital for project success and integrity
throughout the project planning, design,
construction, and documentation phases.
A network of well positioned project control
monuments and bench marks are planned,
constructed and accurately surveyed to serve
as the project coordinate framework. All survey
mapping and layout activities will be based on
this network of control monuments.
PROJECTS CONTROL MONUMENT
NETWORK AND COORDINATE
SYSTEM ESTABLISHMENT
Project control point coordinates and elevations
are typically established using Global Navigation
Satellite Systems (GNSS) static/fast static surveys,
conventional traversing, and differential leveling.
Twozan Surveys have extensive experience in
the establishment of geodetic control point
networks using both conventional and satellite-
based positioning systems ranging from small
project controls to regional and national
geodetic networks. We also have extensive
experience in tying project control monument
network to other local, municipal, national,
and global geodetic control networks. This is
important for interfacing the project with existing
26

27
or future adjacent development projects
and documenting the project for update
of municipal Land Information Systems,
Geographic Information Systems, or for the
generation of the project as-built plans.
We understand the importance of project
control network and its impact on the
project overall integrity and accuracy.
Therefore,weadoptthehighestprofessional
standards in the selection and construction
of survey control monuments in addition to
the selection and implementation of the
right technology to achieve the highest
professional accuracy standards when
determining the position coordinates
and elevations of the control monument

UNDERGROUND UTILITY
MAPPING SERVICES
Most planning and engineering agencies are
faced with difficulties concerning underground
utility line networks with no existing and accurate
as-built maps. As-built maps are rarely available
and when available, they are hard to gather from
various sources, inaccurate and often based on
the design plans not the actual as-built conditions.
This could result in considerable project delays,
costly accidents, infrastructure damage, service
disruption, and increased unforeseen costs.
Twozan Surveys employs different types and
combinations of state of the art technologies in
the detection and mapping of underground utility
lines of various material types and depths with an
unprecedented accuracy and high degree of

HIGH DEFINITION 3D
LASER SCANNING
AND MODELING
Highly detailed and congested sites are hard to survey using
conventional survey techniques due to limited access and
space and for other safety concerns. We have employed
the relatively new 3D laser scanning technology in similar
projects and produced excellent highly detailed 2D and
3D survey results. 3D laser scanning technology has many
advantages over conventional survey techniques.
The surveyed site objects are remotely sensed using laser
beam. Project site can be measured from various standing
points without need for direct contact or occupation of the
measured objects.
Thistypeofsurveyissuitableforsurveyofcongestedroadways;
there is no need for full or partial road closing to obtain the
required survey measurements. The resultant deliverables
are highly detailed 3D replica model depicting the exact
geographic position, dimensions, and actual surface color
of the scanned object or surface in virtual space.
Two and Three dimensional as-built plans can be generated

DEFORMATION MEASUREMENT
AND MONITORING SURVEYS
Deformation surveys are carried out to measure and document horizontal and vertical movement
or settlement of any natural or manmade structure or surface due to external natural or man-made
causes. Deformation measurement data are processed and compared against fixed measurement
baseline to determine the magnitude and direction of movement. It provides specialist engineers
with important input data that will be used in the analysis of the structural deformation and actions
to be taken to deal with the causes/consequences in order to mitigate or eliminate possible risks
and structural safety.
Deformation usually happens in small unseen magnitudes over a period of time. In some
occasions, structural deformation is visually noticed in the form of unusual cracks. This requires
accurate and periodically repeated measurements on carefully selected locations. It can be
done using one or combination of manual or automatic measurement systems to ensure proper
detection of possible deformation.
Deformation happens due to many causes such as natural seismic activity, structure aging, earth
moving activities, piling activities, improper soil compaction, unbalanced structural loads, etc.
Deformation surveys are carried out to monitor
the following sample structures:
› Dams and Embankments
› Rail Tracks
› Tunnels
› Buildings
› Retaining walls
› Bridge supports, beams, and columns
› Landslides and settlements
› Structural Cracks and load testing measurements

GEOGRAPHIC
INFORMATION
SYSTEMS
Geographic Information Systems (GIS) requires human
resources, hardware, software, and IT infrastructure to
collect, store, analyze, present, update, and maintain
spatial and non-spatial information. GIS provides decision
makers and planners with important spatial information
(location-based) and non-spatial (descriptive and
statistical) about the land to make best informed decisions
about planning and management of resources, facilities,
services, infrastructures, and environment.
At Twozan Surveys we understand that successful GIS
projects require good planning and continuous support
from higher organizational levels and commitment from all
organization branches and departments. We also realize

CADASTRAL AND
BOUNDARY SURVEYS
Ownership of the land and what lies on it is the
basis of economic development. As society
grows complex, efficient use of land becomes
a necessity for better living conditions.
Cadastral surveying is concerned with
measurement and delineation of property
boundary and registration and maintenance
of all legal rights in a property. A buyer of a
parcel of land, building or facility is not the
owner until the property is legally registered
and affected.
Property boundary surveys are carried out
to verify existing established boundary or to
establish new boundary such as in subdivided
land tracts. Twozan Surveys has extensive
knowledge and experience is cadastral land
surveys including:
› Construction of boundary monument corners
and boundary line markers
› Preparation of lot boundary maps
› Subdividing parcel of land according to
municipal and ministerial regulations and
laws.
