General refurbishment of the tunnel chain between Inzersdorf and Schön

On Monday, 20 February, Asfinag will start the general refurbishment of the Upper Austrian A9 Pyhrn motorway between Inzersdorf-Kirchdorf and Klaus an der Pyhrnbahn. Until June 2025, four tunnels and their electrical safety installations will be repaired on the entire carriageway in the approximately nine-kilometre-long section, alternating on both lanes. These include the Tretter, Ottsdorf, Kremsurprung and Hinterburg tunnels. In the Ottsdorf tunnel, the tunnel ceiling has to be lifted due to the new ventilation technology. The work will last until June 2025.

Our Geodata Upper Austria branch was commissioned with the surveying work accompanying the rehabilitation of this construction project.

Geodata in the final at GIS 2022

The EUREKA GIS (Global Innovation Summit) took place in Portugal at the end of June. The GIS is an international forum for the exchange and networking of companies, innovators and researchers. Geodata, with its project partners Geodata Andina Chile and 3GSM, was one of three nominees in the final in the category Earth Observation & Monitoring.

The nominated project Defdrone-3D was developed with out partner 3GSM from Austria & Geodata Andina from Chile aa low cost 3D deformation monitoring system allowing the design and execution of an automatic UAV flight mission followed by an automatic processing of 3D deformations from the measured data. The monitoring objects adressed are landslides, rock walls, rock slopes and dams which are deforming due to manifold reasons incl. climate change.

1st breakthrough at the Semmering Base Tunnel

A few days ago, the first breakthrough for track 2 of the Semmering base tunnel was celebrated. This connected the construction sections between Göstritz in Lower Austria in the district of Neunkirchen (Lot SBT 1.1) and Fröschnitzgraben in Styria in the district of Bruck-Mürzzuschlag (Lot SBT 2.1). Thus, more than 24 km, i.e. almost 90% of the 27.3 km long twin-tube tunnel have already been excavated.

We are proud to have made a significant contribution to this success under difficult geological conditions as being responsible for the control survey of the entire tunnel structure and for the geotechnical measurements in Lot SBT 2.1.

VÖBU FAIR and Construction Congress - 2 successful events!

After a long break due to Corona, trade fairs and exhibitions finally took place again in the usual way. In April we were able to participate in the VÖBU FAIR in the Vienna Exhibition Centre and the Construction Congress in the Austria Center Vienna together with our partner VRVis (Centre for Virtual Reality and Visualisation) with an exhibition stand. At the VÖBU FAIR we presented our services in the field of geophysics, at the Baukongress with 2,000 participants the focus was on VR-supported monitoring of tunnel structures. We were also present at both events with a technical lecture.

We would like to thank all visitors to our exhibition booths for their keen interest!

S-LINK - We help realise this future-oriented inner-city transport project

The S-LINK project will make Salzburg’s transport fit for the future and create an attractive alternative to individual commuting.  As an extension of the local railway, the project will connect Salzburg’s main station with the south of the provincial capital and the city of Hallein in four construction phases. The first of four construction phases is the 1 km long underground section from the main station to Mirabellplatz and will start in 2023. For the remaining sections, extensive exploratory work is underway to select the route.

Geodata has already been involved since 2020 with extensive geophysical explorations (seismic and georadar) and the equipment of groundwater measuring wells with piezometers and data loggers. The latest contract involves the instrumentation and measurement of a test field for the planned ground improvement measures with jet grouting and includes georobot systems for automatic 3D monitoring, levelling and borehole instrumentation with inclinometers and magnetostrictive extensometers.
