The project “For healthier and better water in Brno” implemented in cooperation with Brno Waterworks and Sewerage, a.s. and ALS Czech Republic s.r.o. In accordance with the assignment, the project team led by Prof. Hlavínek focused on monitoring the sources of drinking water for Brno and at the same time monitoring the wastewater produced in the city of Brno. As part of the annual campaign, the researchers of the AdMaS Center focused on the content of pesticides, drugs, hormones, microplastics in drinking water and came to a positive conclusion that both treated drinking water and surface and underground drinking water sources for Brno are high quality non-life-threatening micropollutants, hormones, narcotics.
In addition, during wastewater monitoring, they focused on the presence of industrial substances and heavy metals and found that wastewater is polluted as expected and, based on the monitored indicators, contains microplastics, pesticides, but also narcotics and other monitored substances (heavy metals, etc. .). Experts point out that technologies for the removal of micro-pollution in wastewater already exist. However, these are not yet widespread in practice, partly because the legislation of the Czech Republic does not require this.
On March 29, 2022, Professor Lina Sakalauskiené, Dean of the Faculty of Civil Engineering from Vilnius University of Applied Engineering Sciences, visited the AdMaS Center together with Erasmus Coordinator Inga Piščikiené. Director dr. Krejza introduced the AdMaS Center and presented the centre’s research activities. As part of the guided tour of the center, the Dean was interested in the technical equipment and opportunities for research cooperation in a number of construction areas. At the end of the tour of the center, the Dean actively participated in the recycling of unused plastic filaments from 3D printers, from which the equipment of the rest room for students of the Faculty of Civil Engineering in building Z is created.
The tendency to expand green areas in cities also brings news in the area of parking spaces. Experts from the AdMaS science center, led by Ing. Tomáš Chorazy Ph.D., decided to test three types of parking spaces in the new experimental car park. The so-called Sewer gratings, which are common to all three types of parking spaces, allow the rainwater to be drained into the soil instead of the classic drainage, thus helping to combat drought. In addition, the researchers placed biochar under one parking space, which helps to remove heavy metals, pesticides and also cleans rainwater. Modern cities and urban development use biochar for the regeneration of green areas, the construction of green roofs or tree planting, or just to build the aforementioned green parking lots. Now the testing will be transferred from the laboratories directly to the experimental car park. In addition, for example, dynamic impact tests are planned for monitoring the load-bearing capacity within long-term use or monitoring the effectiveness of seepage, etc. The staff of the Faculty of Civil Engineering at BUT cooperated with ASIO NEW, spol. s r.o.
On Tuesday, January 18, the Dean of the Faculty, Construction Professor Bajer, together with other representatives of construction faculties and industrial partners, signed the entrance to the platform of the National Construction Center 4.0.
This platform aims to exploit synergies in the implementation and optimization of digitization, automation and application of the principles of sustainable environmental behavior. The current major challenge for the construction industry is, among other things, the introduction of new technologies, including the use of the principles of Industry 4.0 in construction and increasing the competitiveness of the Czech Republic in this area on a European scale.
The AdMaS center plans to be one big construction testbed.
On 18 August 2021, was ceremoniously presented a new frame 3D printer in the area of the AdMaS Center of the Faculty of Civil Engineering in cooperation with the Faculty of Mechanical Engineering, which enables the use of 3D printing in construction.
A team of researchers led by Dr. David Škaroupka produced 14 parts for a parkour playground in just 10 hours. The mixture from which the obstacles are made resembles concrete, but it is not concrete because it does not contain coarse particles. The mixture is based on a combination of cement, water, aggregate and polypropylene fibers. The parkour playground will be used for leisure activities in the City District of Prague 11. The playground project meets several interesting aspects, such as the sustainability and uniqueness of 3D printing together with active spending free time. This is the first 3D construction printing project in the Czech Republic, which will serve people in public space.
Gasman from GasNet together with representatives of the AdMaS Center of the Faculty of Civil Engineering of BUT organized the first conference in the Czech Republic on 26 May 2021 on the use of LNG in transport and energy. The event took place under the auspices of the Dean of the Faculty of Civil Engineering professor Bajer. Associate professor Zdeněk Dufek presented a global view of the possibilities of higher use of LNG in freight transport, and the issue of fire safety in relation to Czech standards was presented by engineer Beneš.
On Monday, May 3, 2021, Czech Television filmed a robotic 3D printing of concrete in the construction 3D printing laboratory (3DCP) in connection with the forthcoming Czech Television documentary with the working title “Wanderings in the Czech Future”.
An interesting feature of this laboratory is the used printing mixture, which is filled with recycled material from the construction industry.
Along with 3DCP team, 3Deposition, ERC-TECH and Master Builders Solutions also took part in the implementation of 3D printing and interviews.
At the end of 2020, the AdMaS Center, together with its partners, launched a solution for the project “For Healthier and Better Water in Brno”, which was commissioned by the City of Brno. The aim of the project is to gain current knowledge about the quality of drinking and wastewater in Brno with a focus on micropollutants such as medicaments, drugs, pesticides, microplastics, etc.
During December 2020, weekly monitoring of wastewater flowing into the Brno-Modřice Wastewater Treatment Plant (WWTP) took place, which treats this wastewater from the territory of the city of Brno and its vicinity. This initial weekly “screening” provided insight into the amount and species composition of infiltrated micropollution, which was evaluated during January 2021.
The average daily value of micropollution flowing into the Brno-Modřice WWTP consists in total of: about 20 kg of medicaments (the main pharmaceutical substances were paracetamol, iomeprol and gabapentin), 0.5 kg of drugs (pervitin and THC metabolite), 1 kg of pesticides and 0.07 kg of polycyclic aromatic hydrocarbons and polychlorinated biphenyls. In terms of widely discussed microplastics (plastic parts smaller than 0.5 mm), their occurrence was monitored on average 267 particles per liter of wastewater
The project will now continue as long-term annual sampling campaign of quality of drinking water from the city of Brno water sources for the, wastewater sampling at the inflow and outflow of the Brno-Modřice WWTP to evaluate the effectiveness of micro-pollution removal at the treatment plant and wastewater monitoring on the sewer network busy roads.
Assoc. Prof. Tomas Apeltauer, head of the Institute of Computer Aided Engineering and Computer Science at BUT and the main researcher of the National Competence Center project “Rebuild – virtual environment”, which has been solved within the AdMaS center for last 3 years, is preparing a simulation of operation of vaccination centers in the South Moravian Region.
Together with colleagues from the AET Institute, the South Moravian Innovation Center and the University Hospital Brno, they collected data for simulations and are testing the Vaccination Center at the Brno Exhibition Grounds, all with the support of the South Moravian Region. The aim is to make the most of the process and optimize the operation of other regional centers. Every second saved will be a win after the start of a full load.
The team transfers its experience from the first optimizations of the vaccination center at BEG to the preparation of centers in the regions. Last week, they not only focused on the simulations and testing itself (eg the capacity of the initial doctor’s examination before the vaccination itself), but even composed Lego models of the first regional center in Breclav.
Conveniences such as CDE (Common Data Environment) or designs completely in Autodesk Revit are a matter of course throughout the process. BIM is simply applied wherever possible.
We are proud that among our colleagues there are people who are willing to dedicate their free time and without rewards to such important projects.
After less than 7 years, the AdMaS Center changed its management – the Director, Assoc. Prof. Zdeněk Dufek, left his post and handed the position over to his Deputy, Dr. Zdeněk Krejza.
Assoc. Prof. Dufek is still connected to the Center thanks to two projects of the Technology Agency of Czech Republic. The first project, “Safety of LNG filling stations”, on which the Center has been gradually cooperating with GasNet, the Technology Platform and innogy for four years now, will end in August this year. The latter, CAMEB, a large project of the National Competence Center called “Center for Advanced Materials and Constructions” will not be completed until December 2022.
This one includes several sub-projects in which four universities (BUT, CTU, MENDEL and TUL) and many private companies participate. The motivation for its creation was a decrease, resp. thinning of non-renewable natural resources, both material and energy, and the impact of this phenomenon on construction.
During his tenure as director, Dufek also devoted himself to many important government contracts (eg for the Directorate of Waterways, Directorate of Roads and Motorways, etc.), collaborated on the writing of several professional publications and raised awareness of the center’s qualifications at the Czech and international level.
On behalf of the employees, I would like to thank to Assoc. Prof. Dufek for his contribution to the Center, always professional and collegial behavior, and wish the new director, Dr. Krejza, many interesting projects and work successes in the following years.
