Construction surveying
Using modern surveying techniques in the form of 3D laser scanning, photogrammetry and classic surveying measurements, we service construction investment projects in a manner ensuring top quality.
In addition to the classic land surveying documentation, we also offer inspections in the form of non-invasive and rapid scanning and low-light photogrammetry with the use of drones (unmanned aerial vehicles) and ground-based close-range. This allows us to document the condition of the planned investment as of the date of the measurement and verification of the works performed during its lifetime.
Thanks to precise monitoring and application of advanced CAD tools, we are able to control and prevent failure of the investment resulting from design or construction errors. On the other hand, experienced teams of surveyors ensure timely completion of staking out or inventory tasks with the appropriate high accuracy.
Modern technologies used allow us to quickly deliver large amounts of information in three-dimensional data exchange formats (point clouds, 3D models) or orthophotos. Each technology has its limitations, the most important of which is the problem of availability of the object of interest. The equipment base that we have at our disposal allows us to conveniently combine surveying techniques, thanks to which we are able to quickly and efficiently inventory even the most complicated objects on the construction site.
Robotic total stations applied by us allow for greater flexibility of surveying teams on the construction site and significantly increase our availability for subcontractors or general contractor of the construction. In order to meet the market expectations, during the construction we provide modern data allowing for effective construction management in accordance with the BIM methodology.
Under the comprehensive implementation of tasks in the field of investment services, we perform, among others:
Land surveying services for investment projects

- measurements of cross-sections and longitudinal and transverse profiles of linear and engineering objects.
Our products
As a result of appropriate data processing, we can offer several products - both for full 3D and classic 2D work. These are, among others, orthophoto-maps, projections, cross-sections, longitudinal profiles and various thematic maps.
Point cloud
A point cloud is a multi-million point set that is a geometric representation of a scanned object.
Clouds are acquired either indirectly (photogrammetry) or directly (3D laser scanning). There is a possibility to provide a cloud that is a combination of both technologies, which allows for full imaging of a scanned object.
Point clouds are usually so dense that they appear to form a continuous surface. The density of a point cloud depends on the class of scanner, its accuracy settings, and the distance from the object being scanned. Each point has a colour assigned to it, which makes it easier to identify the reconstructed objects in the cloud. Unlike the photogrammetry technique, the acquired point cloud has a scale, so measurements can be performed on it immediately without the need for fitting.
Upon client’s request, the cloud is provided in Polish Coordinate System 2000. Available data exchange formats include: LAS, LAZ, PLY, XYZ, RCP and RCS. Point cloud can be conveniently viewed and measured in Autodesk Recap software. Additionally, it can be loaded into AutoCAD, Microstation, Cyclone or ArcGIS software.
Application: Design, architectonic, visualization and planning purposes
3D model with superimposed texture
3D model with superimposed texture: OBJ, STL, PLY, FBX and 3D PDF.
It is possible to load the file into programs such as Revit, Inventor, Meshmixer, Infraworks, 3D Studio Max and Sketchup and print it on a 3D printer.
Application: Visualization and planning purposes
Orthophotos
Orthophoto-map is a cartometric image acquired as a result of processing a photo taken by an unmanned aerial vehicle (BSP, drone). It is a comprehensive source of knowledge about a given space.
The image obtained from the drone is characterized by a high resolution of the field pixel (at the level of 1 cm), which allows us to identify even the smallest elements of the infrastructure. In contrast to the aerial photo, orthophoto-map has a uniform scale for the entire surface of flat field. The use of drones in surveying work enables the preparation of an orthophoto-map of a given area even of several hundred hectares. The product is georeferenced which makes it possible to read the map in the appropriate software and to make the project and add resources in the form of the basic or register map.
It is possible to load maps with accurate georeferencing into such programs as AutoCAD Map 3D, AutoCAD Civil 3D, Microstation and ArcGIS.
Uses: spatial planning, land registry modernization, environmental analysis, designing construction works, site visualization, detecting changes in the natural environment, creating documentation of natural disasters, quality control of maps and cartographic data
Numerical land coverage model
Numerical coverage model provides precise representation of the existing field, which generates a wide range of possibilities for analysis, comparison, calculation, design and spatial planning.
The available formats are: GEOTIFF, XYZ, LAS and LAZ. It is possible to import the file to AutoCAD Map 3D, AutoCAD Civil 3D, ArcGIS and Microstation.
Videos and photos with editing
Tworzymy filmy w dowolnej jakości – nawet do 4K. Dokumentacja video pozwala na precyzyjną inspekcję
We create films in any quality - even up to 4K. Video documentation allows for a precise inspection of a specific element. We also offer visualisations in the universal MPEG4 (MP4) format which enables a comfortable presentation of an object to a Client, investor or supervisory inspector. We offer taking a very large number of photographs (from several dozen to several thousand - depending on the size of an object) with a resolution of up to 36 MP.
The photos are in a customized format.
Application: Very detailed documentation of an object and its changes over time
We deliver films in MP4 or AVI format.
Application: Very detailed documentation of a specific component
Calculations of volume, area and length
The information is supplemented by an appropriate graphical presentation, authenticating the calculated value.
We use low-altitude aerial photogrammetry technique with the use of non-metric images. The technology involves processing digital images to a 3D point cloud, which is a spatial, finite representation of field consisting of points with coordinates X, Y, Z and the colour value of each point (pixels).
In order to calculate the volume of earthworks, we create numerical field models in the form of TIN (Triangulated Irregular Network) grid in AutoCad Civil 3D software.
The computational task is to compare the created numerical field models (TIN meshes). The difference between the 3D surfaces is obtained and then the values of excavations and embankments between the models are calculated.
Cross-sections and projections
An interesting product for documenting building structures is the orthometric projection.
It is a fully cartometric representation of a specific plane, e.g. a façade, a building front, an acoustic screen or a retaining wall. Saving to a TIFF file enables us to review an object in high resolution. Depending on the Client’s wish, cross-sections may be saved to CAD (DWG, DXF) or PDF files.
Application: Creating a clear architectural and construction inventory (mainly for planned renovations).
3D modelling
3D modelling is a process in which we use software to transform a mathematical representation of an object into a 3D model. The created object is called a three-dimensional model used in branches such as mining, industry, construction or architecture.
3D modelling facilitates communication of ideas, is used to create interactive positioning of objects or surfaces that represent the actual design. It provides control of the real condition with design parameters. It allows us to create a part of a physical object in a very fast time, so we can make analyses of physical properties and then update the model as needed.
Available data formats are: DWG, DXF, DGN, STP and others. Models (solids) are created by us on the basis of a point cloud to maximally facilitate the Client’s work in such programs as AutoCAD Civil 3D, Inventor, Revit or Archicad. Processed buildings, machines or pipe networks give the possibility to work comfortably in the environment familiar to the designer.
Online application - sharing 3D measurements
Our company offers data sharing on platforms such as Sketchfab and Cloud PIX4Dcloud, as well as YouTube.
