Within the IWIQ project, together with our partners, we are researching how urban water cycles can be relieved of pressure and simultaneously used for energy recovery. The focus is on integrating decentralized treatment of lightly polluted greywater in existing buildings – for example, from showers, kitchens, or washing machines. This is treated on-site to produce high-quality process water and initially used for toilet flushing. In the future, it can also be used for washing machines, garden irrigation, building cooling, or infiltration. This can reduce drinking water consumption by up to 60%.
IWIQ thus makes a concrete contribution to two key future challenges: resilient water supply in times of increasingly scarce resources – and the local energy transition in the city. We demonstrate how technological innovation, municipal planning, and existing buildings can be integrated – creating a sustainable circular economy that is transferable and future-proof.

The division Non-Destructive Testing Methods for Civil Engineering promotes the practical application of non-destructive testing (NDT) methods for all areas of civil engineering, improves existing methods, develops new methods and supports the development of regulations.
Challenges as Researcher
My contribution to the research group Non-Destructive Testing Methods for Civil Engineering division at BAM involves data analysis and software development for materials research. Specifically, I am working on implementing machine learning models in Python to enhance the analysis and interpretation of NDT data as well as improving the development of a python-based application designed for the evaluation of Laser‑Induced Breakdown Spectroscopy (LIBS) measurements. It offers tools for element quantification, element mapping, control charts, and more. Currently, the application focuses on 2D measurements of cementitious materials. Key features of the application:
Custom data processing, including denoising, baseline correction, and/or normalization,
Regression models (univariate and multivariate),
Estimation of element maps and profiles,
Filtering and grouping/clustering of data points,
Determination of concrete phases and derivation of cement content

As the core to support the envisioned innovations, we are developing an information system that allows evaluating a building’s circular potential — the Reincarnate Circular Potential Information Model (CP-IM).
The CP-IM will allow to store and capture all required data to understand the potential to extend the lifetime of a building, its building components, and materials, and to find optimal reuse possibilities for each of its elements. It will also enable to trace construction products and materials across different buildings, waste management steps, and construction sites.
Our final goal is to provide the basic technology and insights that will allow construction actors across Europe to regionally apply the Reincarnate innovations for significantly reducing construction waste.
Challenges as Researcher
Increasing significantly the construction and demolition waste utilization, including reuse, recycling and transformation of waste into secondary products.
Increasing by 50% the reusability of construction products post demolition and reducing the down cycling of construction waste by facilitating modular dismantling of complex construction products.
Therefore, the implementation of advanced methodologies, such as machine learning, for evaluating the quality of materials and determining their potential for reuse contributes significantly towards enhancing the sustainability of the construction industry through the promotion of a circular economy in green building practices.

To enable the European construction industry to significantly improve its productivity, while reducing cost and ensuring safe work conditions, ASHVIN will provide the first of its kind digital twin platform that will be completely IoT ready and that will be interoperable with a wide range of design and engineering applications. Through this interoperability, the ASHVIN platform will be able to represent as-designed models. At the same time, through the integration with a wide range of sensors (including photogrammetric sensors) a continuous synchronization between the as-designed and the as-built models will be achieved.

The demonstration of the ASHVIN’s Digital Twin System expands
Since last Spring, 2023, the ASHVIN project has openly invited ongoing construction projects to participate in the demonstration of its digital twin platform. The project partners have been very invested in finding new external stakeholders who want to join this effort by providing sensor data from their construction sites. This effort has been effective; 13 new construction sites external to the ASHVIN consortium have been or are about to be onboarded to the ASHVIN Digital Twin platform!
The freshly onboarded sites come from six European countries, including Poland, Spain, Croatia, Germany, Romania, and Sweden. These included a varied range of assets: two bridge structures, airport infrastructures, family houses and bigger houses, as well as office buildings, such as Habitat7 from Gothenburg in Sweden, managed by our partner, NCC.
On these sites, the ASHVIN partners have supported sensor installations to collect data that helps monitor and assess specific aspects of the ongoing construction project, such as structural safety, health and safety or productivity at the site. The deployed sensing technologies include cameras installed on the construction site, sensors on cranes, drones, and movement sensors. For the first set of these sites, the BIM models have been developed and integrated into ASHVIN’s IoT (Internet of Things) platform, making the connection between the sensing devices and the digital twin tools.

The viability of using digital twin technology and IoT has been proven in pilot projects.
The constant flow of real-time data from IoT sensors combined with historical data from other projects can be used not only in the monitoring of current job sites, but to provide the required historical data for predictive and prescriptive analytics with advanced AI methods.

Sustain.ALL project lab is a way to shape the future with Sustainable Development Goals. Our research question is how can we bring sustainable projects into a digital world to achieve the maximum social, ecological and economic impact?
Sustain.ALL project lab is a way to shape the future with Sustainable Development Goals. Our research question is how can we bring sustainable projects into a digital world to achieve the maximum social, ecological and economic impact?
The module gives an overview of Sustainable Development Goals, related to diverse field of engineering , socio-economic and environmental research through sustainable impact. By working on various projects, which serve the chosen SDGs, the students learn how to make a local contribution to global targets. Before working on the projects, students learn how to independently manage a project through the lecture, how to do scientific research and present input about the topics they have chosen, and how to moderate a virtual/ presence group work. During the project phase, students independently implement their projects together with their team members and project partners of Sustain.ALL. Partner workshops /projects, different conference and seminars allow them to expand their knowledge.

Senior Field Engineer, Site Development Unit
Since 2017, IOM (international Organization for Migration) has continued its comprehensive humanitarian support for lifesaving assistance based on feedback from communities for over 900,000 Rohingya in Bangladesh, who have been displaced from Myanmar, preceded by decades of influxes spurred by systemic discrimination and targeted violence.
IOM's Site development unit aims to improve living conditions and reduce risks posed by natural hazards through improving civil infrastructure, such as stairway, slope stabilization with sustainable materials as well as masonry structure across the camps and building the capacity of skilled volunteers to maintain camp access through drainage and pathways. This also includes site development for new shelter designs, as well as the upgrade of bamboo bridges to modular steel bridges to ensure all-weather access to services for the camp population.
