Engineering surveying is a branch of geodesy that focuses on the application of geodetic principles and techniques to support engineering projects, such as the construction of roads, bridges, buildings, tunnels, and other civil engineering structures. The main goal of engineering surveying is to provide accurate spatial information and geodetic data to enable efficient planning, design, construction, and maintenance of civil engineering projects.

Within engineering surveying, we offer the following services:

• Preparation of 1D, 2D, and 3D geodetic network projects
• Adjustment of geodetic networks based on field observation results obtained through various working methods
• Terrain surveying and preparation of topographic plans
• Geodetic marking of foundations and control points
• Data preparation and interpretation of construction plans
• Monitoring of building settlements
• Processing of measured data and analysis of results

Surveying plays a crucial role in high-rise construction by providing accurate spatial information and geodetic data necessary throughout all phases of designing, constructing, and maintaining tall buildings.

Within high-rise construction, we offer the following surveying services:

• Designing geodetic networks: Planning and layout of geodetic network points.
• Height control and leveling: Precise leveling of the terrain and height control are crucial steps in setting the foundations of tall buildings to ensure stability and balance.
• Geodetic marking: Geodetic marking is used to establish accurate geodetic references on the ground for precise construction and positioning of tall buildings in accordance with the project.
• Construction work control: Geodetic control is used during the construction of tall buildings to ensure the accuracy of dimensions, positions, and orientations of construction elements such as columns, walls, slabs, etc.
• Deformation monitoring: Geodetic instruments are used for continuous monitoring of deformations and movements in tall buildings during construction and after completion to detect potential problems or damages.
• Creation of digital terrain models: Geodetic data is used to create digital terrain models that can be used in the design and simulation of tall buildings to identify potential challenges and optimize design and construction.

A cadastral-topographic plan is a type of geodetic document that combines cadastral data about land parcels with topographic information about the terrain relief and existing features on that land. This plan provides a detailed representation of a specific area, typically in the form of a map, where parcel boundaries, buildings, roads, rivers, forests, and other relevant features are clearly marked.

There are several different methods for collecting data required for creating cadastral-topographic plans, and the choice of method depends on the specific characteristics of the terrain, available resources, and technological capabilities. Here are several common data collection methods:

• Field Surveying: This is a traditional approach involving the physical inspection of the terrain by a surveying team using total stations and GPS. During field surveying, the terrain is measured, parcel boundaries are marked, elevation differences are determined, and other relevant information is gathered.
• Aerial Photogrammetry: This method involves capturing high-quality aerial photographs of the terrain using aircraft or drones. The photographs are then used to generate three-dimensional terrain models and create topographic maps using photogrammetric software.
• LIDAR (Terrestrial LiDAR scanning, aerial LiDAR scanning, and mobile LiDAR scanning): LIDAR technology uses a laser to accurately measure distances to the surface of the terrain. LIDAR is often used for surveying large areas with high accuracy and speed, enabling the generation of detailed digital terrain models.
• Satellite Imaging: High-resolution satellite imagery can be used to collect data about the terrain, parcel boundaries, and other features. These images can be combined with GPS data for geopositioning of features on the ground.

These methodological approaches can be combined and tailored depending on the specific project requirements, goals, and available resources.

Volume calculation is the process of determining the capacity of a space or object, typically expressed in cubic meters or other appropriate volume units. This technique is commonly used in construction, geodesy, mining, and other industries where estimating the quantity of materials, such as soil, rock, wood, or other resources, is necessary. In the context of geodesy, volume calculation is often used to assess the amount of material that needs to be excavated or filled during construction works.

This process typically involves the following steps:

• Terrain surveying: Detailed terrain surveying is conducted to determine elevation differences and terrain contours.
• Digital Terrain Model (DTM): Based on terrain surveys, a digital terrain model is generated, accurately depicting elevation variations and terrain shape.
• Surface determination: Using the digital terrain model, the surface area of the analyzed area is determined.
• Volume calculation: Based on the surface area and elevation differences, the volume of material is calculated using an appropriate mathematical formula. This step may involve various methods, such as Simpson's method, trapezoidal method, or interpolation.
• Validation and analysis: The final results are typically validated and analyzed to ensure the accuracy and reliability of the volume calculations.

Volume calculation can be crucial for planning and managing construction projects, as well as for assessing the costs and resources required for the works. The accuracy of this process is vital to ensure efficient project management and resource optimization.

A utility network cadastre encompasses the registration of linear assets such as power lines, telecommunication networks, gas pipelines, and similar structures. This segment of the cadastre system provides detailed data on the locations, routes, dimensions, and other characteristics of these utility networks.

The utility network cadastre is pivotal for planning, constructing, maintaining, and managing energy, telecommunication, and gas infrastructure. These data enable efficient planning of new projects, resource identification, risk analysis, and optimal utilization of existing infrastructure. Moreover, the utility network cadastre can prove beneficial for repairs, expansions, or upgrades to existing infrastructure.
