Project manager of Asfinag Ing. Hans-Peter Ritter took the morning to give a detailed presentation of the overall project, which was launched in 2017.

The total traffic clearance of the approx. 857 million and 28.4 kilometers long project is scheduled for mid-2025.

Many thanks to Hans-Peter Ritter for the lively presentation of this impressive transport project and for the opportunity to take a tour of the construction site afterwards. We wish further all the best for the project execution!

Marie Pulsinger has been entrusted with the management of the administration department for many years. It is therefore responsible for all internal company processes.

BM DI (FH) Christian Vötsch brought a lot of know-how in the field of project control and project development to Thomas Lorenz ZT GmbH and is currently working on building up the related department.

DI Roland Zmugg is deputy head of department in the Construction Management | ÖBA department and manages the department together with Manfred Grangl.

We are happy about the growth!

With an even broader ownership structure, we are creating a solid basis for entrepreneurial and responsible action beyond the management board.

Thomas Lorenz ‘s team was entrusted by GIG Fassaden GmbH with the structural analysis of the steel structure and the facades of the two connecting bridges and the adjacent building facades in the area where the bridges connect. The architecture was penned by Henry J Lyons, with Arup providing the preliminary structural design.

The centrally placed truss leads to a floating impression. The structural analysis was prepared in close cooperation with the Irish auditor from the Arup office. In addition to the usual verifications, the load-bearing structures also had to be verified for impact sound-induced vibrations. Due to the limited space available on site, the installation concept was a challenge for the company. GIG from Attnang-Puchheim a special challenge. In the end, it was decided to lift the steel structure in individual parts using a 300-ton mobile crane and to assemble the bridge facades later using suspended scaffolding.

A total of almost 110 tons of steel will be used for both bridges. The total weight of both fully extended bridge structures is around 200 tons. Overall completion is scheduled for April 2024.

Essentially, various structural changes will be made to the interior, such as breakthroughs, enlargement of rooms, reorganization of the changing area and the like, to make the building more attractive to users.

Work is currently taking place on the exterior, and the underpinning of the existing building using DSV columns has already been completed. The excavation of the foundation pit is carried out using the pilgering method, whereby a section is excavated and simultaneously secured with a back-anchored shotcrete shell. Currently, the concreting of the clean layer and the shotcrete protection for the excavation pit are being completed.

The general ÖBA and the test statics are taken over by the team of Thomas Lorenz ZT GmbH for this project. Production during operation is particularly challenging.

The team of architects consisting of Zechner & Zechner and Marcel Grabher impressed with their design in the 2020 architectural competition and brought Thomas Lorenz ZT GmbH on board for the structural design. After the “Quadrill” project in Linz, this is already the second project in which the team around Thomas Lorenz is in demand from the Bodner Group in terms of structural design.

The planned building complex will be combined with the actual headquarters of the Bodner Group, which will provide space for approx. will offer 250 employees, and two other independent buildings consisting of 3 structures. For the realization of the “Bodner Campus” on an area of 7,825^m2, construction costs in the amount of approx. 66 million has been budgeted.

Construction started in December 2022, currently. is the shell of the building part 1 on the 1st floor. The completion – so specification of managing director Mag. Ing. Thomas Bodner should be done in a timely manner so that the 2024 Christmas party can already be held at the new headquarters. We keep our fingers crossed for all participants and do our best to achieve this goal!
