The subject of the current examination is the determination of the current prestressing forces within the twelve steel bars as a part of the trussed roof frame construction of the Saarlouis fire station.

The examination was triggered by the failure of one of the stays (at the respective trussed roof frame an unusual deformation had been detected) at the end of October 2021. This led to the question regarding the distribution of the tension forces within the remaining group of eleven components.

On the basis of a non-destructive, dynamic measurement in November 2021 the actual prestressing level in the stays was determined. Thus, a relevant basis for the assessment and evaluation of the current situation and the further procedure was created.

Under the arch concerned an emergency support was erected immediately after damage detection and detailed expert investigations, which are still in progress, were introduced. The fire brigade remained ready for operation without any interruption.

The bridge deck has been completed on 22nd of September 2021 with the casting of the stitch in the middle of the bridge. The remaining works include tensioning of the remaining pre-stressing cables, activation of bearings, tuning of stay-cable forces, installation of parapets and barriers, application of asphalt and installation of expansion joints, lighting, drainage, road signs etc.

Gewan Island Stay-cable bridge provides a connection to the newly constructed Gewan Island, located between The Pearl, Qatar and Lusail.

The bridge design by Dar Al-Handasah defines a complex bridge geometrie with an S-shape in plan view, two pylons on pile foundations and a concrete deck supported by 72 parallel strand stay-cables.

Because the construction has to be performed while traffic on the main traffic connection with the luxury residential area The Pearl Qatar has to be maintained, the bridge is constructed using the free cantilever erection method. Both pylons, the abutments and parts of the deck will be cast in-situ, while the biggest part of the deck will be constructed from pre-cast concrete segments.

Generation and Preparation of strategic noise maps according to EU and Local Environmental Noise Directive for the reporting in 2022.

How high is the actual noise impact in Vienna?

VCE was repeatedly awarded to generate the actual strategic noise maps in the City of Vienna. In intervals of 5 years the European Parliament and the European Council released the obligation to implement the European Noise Directive 2002/49/EG resulting in strategic noise maps considering traffic noise from road and railways, aircraft noise and noise from industrial plants (IPPC plants). To prepare the generation and publication of the strategic noise maps in 2022 FCP is currently collecting traffic data in representative sections on site and starts with three-dimensional mapping of the City of Vienna. Subsequently different scenarios of noise sources and impacts will be generated and prepared for publication.

On the plattform laerminfo.at the strategic noise maps of the year 2017 can be reviewed for each and every location in Vienna.

To refine the noise model the actual traffic is counted at several locations. The results will be adopted to the main traffic network and considered in the noise model.

Additionally a detailed investigation of facades and a three-dimensional presentaton of noise levels at building surfaces shall be implemented in the model.

The wind park Gaweinstal consists of a total of 3 wind turbines of the type Vestas V112 with a hub height of 140 m and a performance of 3.3MW per wind turbine. Now the existing wind turbines shall be replaced with plants with a higher performance. The new plants of the type Nordex N163 have a hub height of 164m and a performance of 5.7MW per wind turbine.

Due to the considerably increased performance the EIA authority demanded a sonic study in which on the one hand the sonic impacts of this change had to be demonstrated with regard to the direct neighbours, on the other hand the concerned region is already at a disadvantage due to sonic exposure by the surrounding wind parks (WP Schrick I & II, WP Paasdorf-Lanzendorf WP Kettlasbrunn I & II, WP Höbersbrunn, WP Gugelberg). Apart from the sonic study regarding audible sound (20 to 20000 Hz) the coactive infrasound input had to be also analysed for the first time. Infrasound is defined as acoustic waves with frequencies lower than 20 Hz and thus below the threshold of audibility of human-beings.

The wind park Parndorf shall be approved in the course of an environmental impact assessment (EIA) change procedure for higher-performance plants. The location of the plants shall be also slightly changed.

In this process the predicted immissions by the planned wind park project Parndorf were assessed and inspected at all the immission points analysed considering the change of the plants and the wind situation.

Which load pattern do you use for track design? In rail track engineering it is common to apply load models developed for design and assessment of bridges as an approximation of loading regimes for rail tracks. VCE’s client questions the traditional approach and is interested in developing realistic load models for track designers.

Multi-body dynamic simulations have been performed to model the dynamic interaction of the coupled vehicle-track-soil domain. Comparison of numerical response quantities with readily available data extracted from measurements of the project VDE 8.2 reveals the superior quality of the novel methodology.

VCE proposes a novel load model consisting of both a realistic load pattern and spectra of dynamic amplification factors. This study contributes to the existing body of modifications to the next generation of modern track design codes. Theory, findings and possible applications will be published on the client’s website in the first quarter of 2019.

At the moment the following models exist:  Family Home for permanent solutions as well as the Emergency House and the Temporary Housefor a flexible use in disaster zones.

GHS Family Home: A GHS family home is a permanent and sustainable housing solution. The housing system consists of a high-quality synthetic formwork which is filled with concrete and should therefore endure natural disasters like earthquakes and hurricanes and be bulletproof.

GHS Temporary House: The GHS “temporary housing” programme is the fastest and most low priced solution for the humane accommodation of persons with an urgent need for housing. The basic model offers space for up to 20 persons. Thus existing family structures or similar social connections can be maintained. This housing type comprises four bedrooms, one kitchen, two separate & furnished sanitary rooms as well as one training classroom on approx. 136 m².

GHS Emergency House: The housing system was developed as emergency accommodation especially for disaster operation. The house is built on a wooden foundation so that it can be easily demounted and re-erected somewhere else anytime if necessary.

Three new traffic light symbols on the topic of diversity were designed for 49 selected pedestrian crossings in Vienna. The design shows one symbol each for red and green traffic lights.

Traffic safety – raised awareness during the red phase – and conveyance of up-to-date social topics (diversity) are the focuses of this campaign. It was important to us to represent the contents in a congenial and positive way. It had to be considered that the fixed size of the light signal diameter only allowed a limited illustration. A quick perceptibility of the contents without affecting traffic safety was essential.

The section U1/13 "Turnout System Favoritenstrasse" is part of the extension of the underground railway line U1 from the station "Reumannplatz" to the district Oberlaa. The Tunnel will be constructed on one hand with the open cut method and on the other hand with the cut and cover method. The temporary construction pit will be managed with several pile walls. In total, 870 bore piles will be deepened with a total length of approximately 12 km. Theexcavation at this construction stage amounts to approx. 80,000 m³. Currently, the last bore piles are produced and the excavation and structural works are running at full speed.

Starting in August 2014 the first load tests were carried out at the new route VDE 8.2 Erfurt-Leipzig/Halle. Subsequently test runs at different speeds up to a maximum speed of 330 km/h were performed with ICE-S trains.  

In the scope of these tests VCE determined the longitudinal stresses of the rails at a total offive measuring sections on three viaducts (Scherkonde valley, Unstrut valley and Saale-Elster valley). Among other things, they served for the verification of the calculations carried out by VCE in the scope of track system design.

In a total of six weeks 16 new measurement systems with 130 strain gauges and approx. 3000 m of cables were installed. In addition a further section was instrumented with four accelerometers and 36 displacement transducers for the determination of track system deformation.

The measurements of the test and load runs with up to 330 km/h were subsequently supervised on site for a further four weeks. All in all the test runs showed that the behaviour of the track system is non-problematic.

The fortress of Golubac including accessory projects shall be turned to a major tourist attraction of the region. For this purpose the historic and listed fortress of Golubac is revitalized and expanded by tourist facilities. Currently a road passes through the fortress (approx. from the 13^th century). For touristic utilization of the fortress this road has to be relocated. In the course of this new road (length approx. 800m) a tunnel has to be built as well (approx. 200m).

For an increased touristic attractiveness of the region a new visitor centre with connected archaeological park is established. In addition the Danube bank in the area of the project is equipped with a pedestrian and cycle path.

Furthermore a pier will be erected, which should enable tourists and persons passing the fortress by boat to visit the fortress.

The construction and revitalization works are carried out in close cooperation with the authorities for archaeology and the department for monument protection.

The project is funded by the European Commission, the implementation of the project and the administration of the budget is performed by the Austrian Development Agency (ADA) – the Agency for Austrian development cooperation.

On 22. November 2013 the last two platforms (8/9) of the new Salzburg main railway station were put into operation.

During the four-year reconstruction phase the important TEN junction became a modern through station. The reconstruction works took place under full operation of the station and were continuously supervised by the Austrian authority for the preservation of historical monuments.

The total reconstruction comprises 4,000 m² of leased areas, 3,200 m² of technical facilities/infrastructure and 2,800 m² of passage/ exploitation under the tracks in the new part as well as approx. 10,000 m² of useful area in the existing building.

The successful integration of both historic arched roof structures into the modern platform roof with approx. 22,000 m² was awarded the Austrian Design Prize and the European Steel Construction Prize in 2013.

The existing Pavilion 4 of the geriatric centre Baumgarten in 1140 Vienna, which is a listed building, is currently reconstructed to a multi-purpose hall. The two existing brick masonry vault and the roof structure are completely demolished. In the interior several reinforced concrete frames and a new reinforced concrete floor is built. As only about a third of the existing pavilion is used as multi-purpose hall, the authorities required a complete separation of the two buildings. For this purpose a 4 cm wide earthquake joint is cut into the existing approx. 60 cm wide masonry by means of a wire saw.

In the scope of the innovation test runs 2012 on the new route Vienna – St. Pölten extensive measurements were carried out at a total of 9 measurement sections.

The measurements comprise the recording of sound emissions on the free route and in the tunnel, the effectiveness of the floating track slab systems in Lainzer Tunnel, the dynamic interaction of bridge structures, the effectiveness of a noise protection wall near a track and the behaviour of the track system in case of velocities up to V = 330 km/h.

On the basis of the recorded measurement data important findings regarding safety relevance, effectiveness and efficiency could be acquired. The surveys prepared represent the basis for the start of operation of the route in December 2012.
