Engineering Geodesy

For solving tasks in construction for the needs of various professions, we perform all necessary geodetic works depending on project type and investor's requirements. While doing so, we use a variety of engineering and satellite geodesy methodsthat require the best equipment and high expertise, and thus provide an extremely high accuracy of our work. Field of application of these methods is wide, from registrating of the current situation for the design of new facilities and reconstruction of existing ones, to monitor the construction of new facilities, preservation of natural and cultural heritage, modeling facilities and development of GIS.

Geodetic survey

The basis of creating every quality preliminary / main project or planning serious activities in the landscape are accurate and updated geodetic surveys, which create as much as possible realistic insight into the area of operations in the landscape. We deliver created geodetic surveys in all formats supported by most modern software solutions.

Stake out

According to the architectural project placed on the cadastral plan facility is staked out (placed) using geodetic methods actually in the field. Depending on the type of project and the required accuracy we implement appropriate methods of staking. With sole staking out of the building we provide staking report.

Monitoring construction

Various influences on the built objects cause their relative movement in space (usually subsidence). In order to determinate these movements the planned and systematic monitoring of the construction is necessary, within which we create the project of geodetic basis and from it we observe movements and changes.

Supervision

We own the consent for professional supervision of geodetic works in construction. For the construction of large and complex structures constant control and supervision are required in order to avoid mistakes that can have a significant impact on the construction of the building, resulting in an cost increase of the project.

Geospatial analysis

Acquiring 1D, 2D or 3D data we conduct all kinds of their spatial (relative) analysis, but also observe them in fourth dimension (4D) in the case of repeated observations. We provide full support and development of complete products with a visualization in spatiotemporal analysis.

PROJECTS

Monitoring the removal of the facility and earthworks with volumetrics calculations of terrain change

SENSA NEKRETNINE d.o.o.

k.o. Vrapče

The project included the development of a digital terrain model based on aerial photogrammetric images in a total of 10 observations. The volumes of terrain change were calculated from the differences of the digital terrain model.

Monitoring the displacement of the construction pit, subsidence of the foundation plate and the slope of the constructed road

FEAL IN d.o.o.

k.o. Središće

The project included the observation and monitoring of benchmarks placed on the main beam of the construction pit; monitoring the subsidence of the foundation plate of the building with precise leveling and calculating the slope of the constructed road.

Slope of the constructed road

Terrain difference volumetrics calculation

Grad Zagreb

cadastral municipality Sesvetski Kraljevec

The project included the development of two digital terrain models based on aerial photography. Digital terrain models are made with a lag of 10 months, and their difference calculated volume difference on the terrain (subsidence and new materials).

Monitoring shoping mall construction

Zagreb beton d.o.o.

cadastral municipality Pešćenica

While monitoring construction complete geodetic support in construction works has been provided. We've set geodetic base on the site that was used for the setting out on the batter boards and referencing 3D models. Every week we've made a 3D model of the site that was used to calculate the cut and fill volumes of materials, and creating profile lines.

Monitoring residential building construction

Nivogradnja d.o.o.

cadastral municipality Trnje

The project included development of geodetic survey, staking out the building on the terrain and on the batter boards and creation of 3D model from which we removed the object for the purpose of calculating the volume of excavation.

The transition of the main pipeline Rogatec-Zabok over the river Sutla

PLINACRO d.d.

cadastral municipality Hum na Sutli

The project included a detailed altitude site map and Sutla river profiles development in the transition region of the main gas pipeline Rogatec-Zabok across the Croatian border with Slovenia. During the project, the identical points on the terrain in GK5 projection were observed that enabled connection of our data with colleagues from Slovenia. As a part of the project characteristic points on the ground were staked out.

DSM analysis and heliport corridor proposal

Agrokor d.d.

cadastral municipality Pešćenica and Žitnjak

Developed DSM has been analyzed for the purpose of creating proposals for possible takeoff and landing heliport corridors. The analysis included calculating the difference between conical surfaces of different inclination and height differences relative to a heliport reference point and DSM. On obstacles layers made in relation to the specific criteria proposed corridors have been constructed in WGS84 system.
