DECARBONISATION FIRST

Methods for CO2 balancing in the life cycle of infrastructures

Winning project of the VIF 2020 tender (traffic infrastructure research in the field of climate protection)
 

Status Quo

50% of the world-wide CO2 emissions can be directly or indirectly allocated to the building industry - enabling an enormous saving potential for their carbon footprint. In the sector of civil and underground engineering the decisions have been predominantly taken on the basis of the expected structural life-cycle costs (=primary costs) to date, e.g.: in the course of tenders and competitions. There is no tool generally applicable to the sector for the calculation of consequential environmental costs yet.

DECARBONISATION FIRST follows the idea that future decision-making for building measures will be based on a considerably higher weighting of costs due to the carbon footprint while it aims to increase the acceptance of the associated primary costs at the same time.

Methods and Procedure

The objective of the research project is to create a database with CO2-equivalents representative for Austria (“Cradle to Grave”) for the relevant building materials of infrastructures (bridges, pavement, dams, retaining walls, trough constructions). For this purpose, a methodology for the connection of a life-cycle cost calculation with CO2 balancing (ÖNORM EN ISO 14040 Ökobilanz) considering the spreading of the input parameters is developed.

For the performance of variant analyses of infrastructures, a practical calculation tool is created which determines costs and CO2 equivalents over the whole life cycle (manufacturing, construction, operation, demolition, disposal/re-use). The methodology and the respective benchmarks and parameters are subsequently summarized in a guideline.

Perspective

DECARBONISATION FIRST provides a major instrument for shaping the resources applied in the course of a building project along the value-added chains with increased environmental responsibility to reach the national climate protection targets.

The project addresses the impending compensation payments of the republic of Austria for the purchase of CO2-certificates amounting to billions of euros and pursues the objective to reduce the share allocated to the civil and underground engineering sector within the shortest possible time to the highest possible extent. In the last few years climate protection has dramatically gained significance in society. DECARBONISATION FIRST immediately meets this social responsibility and ensures that the civil and underground engineering sector can make its contribution to the achievement of the climate protection targets in a measurable form.

Project Status

By the end of April 2022 the mid-term meeting took place with all the project partners and the clients. There the essential milestones already reached, i.e.: “methodical development” and the “elaboration of a detailed GWP catalogue for the addressed assets and their elements”, were presented.

Furthermore, first insights into Work Package 5 “Simulation calculations” were given by providing a comparative prediction of the whole noise barrier portfolio of ASFINAG including

• estimated reinvestment realization quantities,
• expected costs
• as well as the associated Co2 balance

for the upcoming 15 years.

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.

The university at Vienna’s Schillerplatz has been elaborately rehabilitated and extended for the last three and a half years. By autumn the final works shall be concluded and the Academy of Fine Arts shall shine in new splendour. The normal study programme shall be resumed at the beginning of the winter semester 2021/2022.

The listed building with 17,300 square metres of existing useful area and 500 square metres of new useful area as well as 1,000 square metres of open areas was erected between 1872 and 1877 according to plans by the architect Theophil Hansen.

In the course of the construction works extensive restoration of floor, wall and ceiling areas, furniture as well as ceiling frescoes was carried out. Historic doors and windows but also parquet and terrazzo floors were renovated. One of the new elements of the Academy is the establishment of a subterranean depot including a study room in front in one of the courtyards of the building.

Due to the renewal of the technical building equipment as well as a reinforcement of the exterior windows and roofs it was possible to create a modern university site from the historic building.

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.

Four underground railway lines are being constructed on a total length of 172 km in Doha, Qatar, in the scope of phase 1 of the Doha Metro project. At the end of May track slab design was approved by the Design Verification Engineer DVE. Furthermore the noise and vibration assessment was completed and the effectivity of the mass-spring systems was verified in a 1:1 in-situ test.

The track system is currently under construction. It is designed as ballastless Porr slab track system including light and heavy mass-spring systems as required. All in all approx. 80% of the precast track slabs have been already produced and are being installed continuously. The section comprises tunnel, at-grade and bridge sections. In addition turnout areas and the associated transition areas on ballastless track were developed and planned. The track design was revised and adapted for the installation of the slab track system.

VCE carried out noise and vibration assessment determining emission reduction measures (e.g. mass-spring systems) for providing the protection targets regarding vibrations, ground-borne noise and airborne noise. In order to verify the effectivity of the proposed mass-spring systems, true size mock-ups were installed, tested and their performance was verified.

The section of Phase 1 is to be put into operation in 2020, in due time before the start of the Football World Cup in 2022.

The existing, approx. 95 m long, network arch bridge consists of a timber arch and a prestressed concrete bridge deck, which is suspended by means of 68 prestressed steel rods (MacAlloy system).

The aim of the current investigation was the measurement-based determination of the effective forces of all 68 rods of the network arch bridge during the individual construction phases and 12 months after completion with BRIMOS^® Structural Health Monitoring.

The basis for investigation was geometrical information on all tie rods and the corresponding product specifications. According to the bending beam theory of mechanical engineering an analysis tool for the determination of the tension forces was established on the basis of the measured eigenfrequencies and applied in the course of the attendant dynamic construction element measurements.

After numerous adjustment processes the road surface project Herrengasse was released for implementation. The privately financed road project represents an important axis between Freyung and Michaelerplatz. In this section several palaces, hotels, ministries, Vienna’s first high-rise building and the Loos house are located. Apart from Herrengasse, Fahnengasse and parts of Wallnerstrasse are reconstructed as well.

With the implementation of the project this area receives an adequate surface for underlining historically important buildings. Apart from the new high-quality pavement (Austrian granite), lighting is also brought to the state of the art. The existing traffic organization is modified to a shared zone, which creates more areas for pedestrians and pavement cafés.

The preliminary works – installation of fixtures – will start at the beginning of April 2016, the actual surface works will start at the end of May 2016. The conclusion of the works is expected by mid-November 2016.

Low-cost residential buildings were developed , which can be quickly and easily assembled, with the company GHS Global Housing Solutions. 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.

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.
