TERRISTRIAL 3D LASER SCANNING AND SPATIAL IMAGING

Terrestrial 3D laser scanning is a ground based technology used to measure the position and dimensions of objects in 3D space.

The laser beams are directed in various orientations by a system of mirrors combined with an instrument rotation. The horizontal field of view is 360 degrees while almost 310 degrees in vertical direction are possible. State of the art laser scanners offer an accuracy of about 0.1 mm. The data created by the scanners in the form of a long list containing either Cartesian (XYZ) or polar coordinates (vertical and horizontal angle) along with an additional information on the intensity (reflectance) of the received signal. These data can be visualized in 2D image but actually describes 3D cloud of detected points in space, a so called ‘point cloud’. Twozan Surveys employs a combination of stationary laser scanning and vehicle mounted mobile mapping systems on projects requiring full details and for various engineering, planning and asset management applications.

Topcon high Density 3D laser scanning and digital imagery mapping System

The IP-S2 HD vehicle-based mobile mapping system provides fast, high accuracy, high density data and dynamic imaging for any linear mapping project. It collects data at normal roadway travel speeds. Safety is improved by removing data collection personnel from vehicular travel areas.

Accurate vehicle positions are obtained using three technologies: a dual frequency GNSS receiver establishes a geospatial position; an Inertial Measurement Unit (IMU) tracks vehicle altitude; and connection to external wheel encoders obtains distance information. These three technologies work together to sustain a highly accurate 3D position for the vehicle even in locations where satellite signals can be blocked by obstructions such as buildings, bridges, or tree lines.

It features a rotating LiDAR sensor with 64 internal lasers that capture targets up to a range of 100 meters. The sensor’s 360ř horizontal field of view provides full coverage of scan areas with a 30 vertical field of view to minimize laser shadowing. A six-lens digital camera system produces 360 degree spherical images at user-defined time or distance intervals. Five optional single-frame cameras can be added for focused, forward-facing views. Scanning at 700,000 points-per-second, the rotating LiDAR sensor captures the 360-degree environment with 32 internal lasers. The IP-S3’s six-lens digital camera is designed to provide data-rich results with its 30 MP panoramic imagery.

› Leica Photogrammetry Suite LPS 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.

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

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, we adopt the highest professional 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 network.

We advise our clients to plan their project coordinate system and control network monuments as early as possible during the project initiation phase to ensure successful completion of the project. For assistance or more information, kindly contact one of our client relations representatives.

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.

This type of survey is suitable for survey of congested roadways; 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 from the 3D model for any top, side view, or cross section which can be used for any other engineering design application on any industry standard CADD application. The generated 3D model; tied to common reference coordinate system, reflecting the exact dimensions, shape, and location of existing facilities and structures greatly assists

32

33

the design team best fit newly planned expansion structures or facilities with great certainty.

Digital photos are captured along with the scanning process from colors and textures of the scanned surfaces are projected into the final 3D model which helps the end user visualize and walk through the project site on his computer screen without any need for repeated site visits.

3D Laser scanning generates more details and therefore enables more versatile use of the generated object model.

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

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. › Preparation of legal description of land boundary › Land boundary retracement surveys according to existing legal and survey records › Determination of boundary encroachments and resolution of boundary conflicts. › Locating easements and restriction on land use. › Survey of actual and apparent improvements such as dwellings, garages, sheds, driveways, roadways, utility line connections, swimming pools, farming areas, etc. › Survey of property adjacent roads and right of ways.
