SIMULATION OF OPERATION OF VACCINATION CENTERS OF THE SOUTH MORAVIAN REGION

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.

CHANGE IN THE MANAGEMENT OF THE ADMAS CENTER

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.

EXTENSION OF THE CAMEB PROJECT

In December 2020, the Technology Agency of the Czech Republic approved an application to extend the Center for Advanced Materials and Efficient Buildings project. CAMEB thus received funding by the end of 2022. 11 of the 12 original sub-research projects will continue.

The motivation for the establishment of the National Competence Center CAMEB was the decrease, resp. thinning of non-renewable natural resources, both material and energy, and the impact of this phenomenon on construction.

The National Center for Competence CAMEB (Center for Advanced Materials and Efficient Buildings) was established in 2019 in cooperation with the Czech Technical University in Prague, Brno University of Technology and twenty-eight other partners – universities and especially private companies. CAMEB associates partners with such competencies that will enable them to find better use of resources in construction. Based on life cycle optimization, we will be able to design better buildings using the principles of knowledge and circular economics. To do this, we also use modern technologies in the field of digitization, optimization, modeling and effective process control.

One of the goals of the CAMEB center is to develop direct cooperation between universities and companies on the basis of contract research, ie without state support.

NATIONAL COMPETENCE CENTER PROJECT – REVOZIM: RECYCLING OF WASTE AND SLUDGE IN THE FRAMEWORK OF GREEN URBAN INFRASTRUCTURE

A partial goal of the REVOZIM project is the installation and operation of a functional unit (fully instrumented models) for testing green roof compositions. The project activity is related to the partial design of suitable water management in an urbanized area, given that the watering is obtained from the so-called gray water, resp. white water, ie treated, slightly polluted so-called gray water from bathrooms, kitchens, laundry, etc.

The composition of the green roof is prepared as an innovated substrate, made on the basis of recycled materials – bio-coal and recycled material from construction waste. A disadvantage of currently commonly used substrates is the fact that the main components are primary rocks (for example spongilite, which must be mined in nature) or primary products (for example expanded clay, with high energy intensity of production). Substrates that use a high proportion of biological materials, such as tree bark, are at risk of rapid loss of green roof mass due to biodegradation.

The output of this part of the project are basically two utility models – a substrate for laying foundation carpets and a substrate for green roofs. Both of these substrates respond to the above-mentioned disadvantages and in accordance with the principles of circular economics, the presented innovative solution then replaces some of the primary materials with recycled materials. The first recycled material is recycled building material based on crumb brick. The second recycled material is biochar – pyrolyzed sewage sludge.

ADMAS HELPS IN THE CORONA CRISIS

 

The AdMaS Center heard a call for help from Mother Rosa’s Home for the elderly in Rajhrad, which was struggling not only with a lack of staff, but also with a disappearing supply of protective equipment.

Dozens of protective shields printed on the 3D printer of the Faculty of Civil Engineering under the leadership of Assoc. Prof. Jan Pencik were delivered into the establishment. These are used in the home not only by the permanent staff, but also by a number of volunteers who decided to help those in need during this difficult time. One of the Centre’s employees also offered his time and willingness to help and spent weekends taking care of the home residents.

GENERAL MEETING OF THE NATIONAL CENTRE OF COMPETENCE CAMEB PROJECT

On October 15, 2019, the online General Meeting of the CAMEB National Competence Center project was held online. The meeting was opened by the Chairman of the Board, Assoc. Prof. Ferkl from the Czech Technical University in Prague, who informed that in connection with the information provided by the Technology Agency of the Czech Republic (TA CR), it is possible to request an extension of the existing center of competence by two calendar years.

Given the fact that there was a time shift in the original intention of TA CR to announce a call for NCC II and NCC II projects will probably be financed only from year 2023, the extension of NCC I provides an opportunity to bridge the transition period of 2021 and 2022. It was confirmed from the solvers of sub-projects that they have the content and financially secured research content for the years 2021 and 2022 ready.

Some members are no longer interested in being part of the project from 2021, on the contrary, other entities have expressed interest in joining, which was approved by the General Meeting and will be taken into account in the amendments to the contract.

The wording of the Annual Report and the resignation of one of the members of the Board and the appointment of his deputy were also agreed.

Furthermore, Assoc. Prof. Ferkl pointed out that the mandate of the other members of the board would end and therefore proposed the re-election of all members of the board, which was subsequently approved.

NATIONAL CENTER OF COMPETENCE PROJECT- ADMATEC

UNDERLAYERS WITH A HIGH PROPERTY OF SECONDARY RAW MATERIALS

As part of the solution of the ADMATEC sub-project, which is a sub-project of the CAMEB center, one of the topics is focused on stabilizers for the base layers. In addition to experienced researchers at the Faculty of Civil Engineering, Brno University of Technology, the research team also includes students of doctoral, master’s and bachelor’s degree programs. One of the student of the bachelor’s program under the professional guidance of prof. Drochytky devoted herself to the possibilities of using secondary raw materials for soil-based stabilizers. As part of her activities mainly verified products after coal combustion and construction recyclates. The results of her work then confirm that a 20% replacement of soils with secondary raw materials is clearly possible. The materials achieve parameters comparable to the original mixture and in some cases even exceed them several times.

UNIQUE SUSPENSION FOR EARTH STRUCTURES

One of the topics of the ADMATEC sub-project is focused on suspensions for earth structures. This is a unique solution of earth structures using liquefied soils, which makes appropriate use of the self-compacting effect of the suspension, which perfectly fills the excavation space and within 24 hours becomes walkable and ready for further construction work. At the same time, it reaches the parameters of the original soil and is re-excavated by classical technologies. As part of the research activities, a student of the bachelor’s study program also took part in solving partial tasks. These were mainly ashes and recyclates. The conclusions of his work confirmed that 20% replacement of soil with secondary raw material in most cases not only does not worsen the parameters of the original mixtures, but in the case of fluid ashes increases the strength of the mass several times with a significant reduction in shrinkage.

NATIONAL CENTERS OF COMPETENCE PROJECT – REBUILD: VIRTUAL CONSTRUCTION BECAME A NEW REALITY

The aim of the project is the development of a virtualized environment as a tool for communication of individual participants in the design of a building. Communication in this environment will be audiovisual, ie in addition to the audiovisual presentation, it will also allow its recording. The record will then serve as a basis for editing the visualized intent.

Proven technology “Interconnection of software components of the building information model and virtual reality”

Verification of the functionality of the connection of the building information model (BIM) with the virtual reality (VR) engine (software) on the Unreal platform. Proven technology is a necessary starting step for the subsequent development of a real superstructure over this VR engine, which will enable
interactive work in a fully virtualized environment.

Unreal Engine (UE) was chosen as the basic programming environment for the proven technology of this grant, as it provides a wide range of programming options compared to other platforms. Specifically, Unity was still considered, but at the time of choosing the strategy and starting operations (01-05 / 2019) did not have the appropriate tools to view architectural BIM models and convert them to a VR-enabled engine.

Thanks to the template for collaborative views, which began to develop under the UE in 2018 and the Datasmith-software plugin for converting BIM models into the UE, it was possible to load models including metadata, ie non-geometric information of individual elements of the BIM model. Currently, the aforementioned Datasmith supports a large number of formats for CAD / BIM software, including IFC and RVT. Our goal is to develop a collaborative tool for BIM models, created on the Autodesk Revit platform for its widest use on the market for collaboration between professions involved in building a BIM model. Within the proven technology, the activity was focused on the issue of information transfer between the RVT model and the UE, where the goal is to transfer not only geometry, but especially metadata.

Software tool for audiovisual communication in a virtual environment

A tool for the use of virtual reality as a means of communication during the design of a building. The communication will be audiovisual, ie in addition to the audiovisual presentation, it will also enable its recording. The record will then serve as a basis for editing the visualized intent. The  information model of the building will be the input data that will be virtualized.

The project is developing a software tool that allows you to share your stay in a virtual environment, to which users connect from multiple computers and platforms. Within one “world”, users accessing from the desktop PC / Mac environment as well as users using VR technology can cooperate with each other. Within this world, users can move either by virtual walking or by virtual teleport. In this virtual world, there is a building model (s) that carry metadata obtained from Revit architectural software. This information is readable to the user by the user marking the element. Selected elements can be moved by the user for a better idea of ​​possible modifications.

Professional book The use of virtual reality in the design of buildings

A professional book describing the use of virtual reality during the complete process of building design, including testing its functionality and safety. The publication will focus on issues of building representation in a virtual environment, design planning, work coordination and analysis
design safety for users.

URBAN WATER XX CONFERENCE

 

 

 

On  October, 1 and 2, 2020, under the auspices of the expert group “Drainage of urbanized areas CZWA” and the Research Center AdMaS, firm ARDEC organized already XX. year of the URBAN WATER CONFERENCE 2020 in Velké Bílovice . The media partner of the conference was stavební server.com, the magazine Vodní hospodářství and the internet portal Vodovod info. The main partner of the conference was the company PREFA Brno a.s.

The URBAN WATER 2020 CONFERENCE has traditionally maintained a high level of presentations. The conference program was divided into 3 blocks. A total of 24 lectures were presented. Due to the difficult situation with COVID19, a number of delegates excused from conference, often at the last minute. Therefore it was decided that the lectures would be broadcast live using Microsoft TEAMS and that selected lecturers would also be allowed to deliver their lectures online.

The first day of the conference ended with a social evening in the riding hall of the state chateau Lednice. The event attended about 70 delegates which led informal discussions and gained personal contacts. Cimbalom music was played for listening, Moravian wines from top wineries and rich refreshments were prepared for the participants. The social evening was, despite the strict adherence to all currently valid measures and restrictions associated with Covid 19, very positively evaluated by the participants.

The twentieth year of the conference confirmed that the URBAN WATER CONFERENCE maintained the favor of participants despite the difficult situation, as about 100 delegates from research institutes and universities, design and supply companies, sewer operators and municipal councils, etc attended. Other participants had an opportunity to watch the online broadcast of lectures.

Preparations  of the XXI. URBAN WATER CONFERENCE, which will take place on October 7 and 8, 2021, have already started. Conference will traditionally focus on water management in 2021, water resources, ensuring the need for water from alternative sources, the concept of urban drainage solutions, urban watercourses, flood protection in relation to urban drainage, progressive technologies of wastewater treatment, technological WWTP processes and experience from the implementation of urban drainage constructions. A special section will also be devoted to contributions related to the COVID 19 pandemic.
