The City of Brno’s new zoning plan is now available to view as an online exhibition, as a joint project of the Urban Center and the City Architect’s Office (KAM), which also drew up the proposal. The online exhibition outlines the origins of the plan, and explains in detail its importance to the city.
The “Exhibition of 381,348 Spatial Planners” was set to take place in the Urban Center, but the ongoing epidemic situation means it has moved to a virtual environment. The name of the exhibition is a reference to the population of the city, as the organisers want to encourage participation in the public consultation over the plan.
The exhibition covers all aspects of the plan that are important for the development of the city. KAM identified nine “burning questions”, which are dealt with in detail, including urban greenery, the city’s allotment sites, and bicycle transport. The exhibition also provides information about strategic locations in the city where new buildings or even entire new neighbourhoods are planned, and the revitalisation and new uses of brownfield sites. The draft zoning plan views the city as a living and ever-changing organism.
Apart from designing the new Brno main train station itself – from the platform to the roof, the interior to the façades – the competing architectural teams had to submit concepts for connecting bridges and related public spaces.
They also had to identify the optimal location and appearance of a new bus station, public transport terminal, car parks, taxi stands, bicycle storage and pedestrian access. What’s more, as the construction will be part of the Trans-European Transport Network (TEN-T), designs must account for a range of interconnections.
At the Brno University of Technology, a collapsible 3-D model of the existing site is now being built, using a range of thermoplastics and machine-tooled wood. The nearly “million-crown” model will be akin to a giant puzzle on a 1:500 scale, which the teams competing to design the train station can modify as they see fit.
Michal Sedláček, head of the Brno City Architect Office (KAM), told Czech Radio that the city had will use the 3-D models not only to assess the competing teams’ designs, but also to assess high-rise building projects that should sprout up in the new Trnitá district around the train station.
The model, representing an area of Brno two kilometers long and one and a half kilometers wide on 12 square meters, will be used by the expert jury to choose the winning design from the 12 currently being prepared. Experts from FAVU are constructing the model from wood, and by means of 3D printing. Two thirds of the terrain is already complete. The finished model will include hundreds of buildings, over 2,000 trees, train and tram tracks, and the river Svratka as a significant landscape element, all at a scale of 1:500. The competition teams will insert their proposed buildings and other elements directly into the model, allowing them to be evaluated from a vantage point and in the context of the whole district.
The twelve competitors are now working on their designs for the new station by the river. Four of them will be selected for the second phase of the competition, in which they will complete the proposals in greater detail, including physical representations of the competition area to be inserted into the model of the new district. In July 2021, the jury will select a winner and determine the order of the second, third and fourth place entries.
The entire finished model, including the winning form of the main railway station, will be presented to the public in the autumn of this year, where it will be the centrepiece of an exhibition of competition proposals.
The 3D map allows you to display up to 14 categories of buildings divided according to their purposes, such as housing, commerce, sports, recreation or gardens. It can be easily searched by address. Users can change the types of background map or enable shadows to be displayed based on current time. They can view information about multiple buildings at once, using the shift key. Even in a 3D model, buildings can be distinguished by their purposes, or even by floors as in the previous 2D applications.
In two years, information was collected on approximately 110,000 buildings, from which our data specialists calculated gross floor areas, roof type and height using spatial and statistical analyses. So far, they have modelled the historical centre of Brno as part of the 3D solution, and they are now working intensively to extend the map to the outskirts. The pilot 3D map project was presented for the first time in October at an exhibition called “381,346 Spatial Planners” in the Brno’s Urban Centre. Based on the feedback from its users, they want to continuously update the map.
Depth measurements using a ground-penetrating radar should now reveal the condition of the building and whether it can be saved. The test measurement of the first section took place on Tuesday, December 1, and it was organised by the Brno City Chief Architect‘s Office.
The test measurement of the first section includes the first five arches, i.e. about fifty metres from the Malá Amerika building to the south. The results of the first measurement will be available at the beginning of next year. If the measurement method proves successful, we plan to measure the entire route of the viaduct to the bridge over the Svratka River.
It has not been known for decades whether the original viaduct still exists under the railway embankment and what its condition is. Therefore, we were looking for ways to focus survey the construction under the existing track. If the viaduct can be saved, it will be a significant building and one of the dominants of the new southern district Trnitá. It will serve as a city esplanade from the centre to the Svratka River, similar to the famous High Line in New York.
The Viennese viaduct in Brno was built during 1838 by the Emperor Ferdinand Northern Railway as part of the line between Brno and Vienna. The actual brick viaduct with 72 arches supported a single track and it was a total of 637 metres long. It was followed by a five-arch bridge over the Svratka River, which preserved to this day. Only a few small sections of the original viaduct have been preserved, because during the widening of the track in the 1890s, it was largely buried and hidden in a massive embankment. Fifteen brick arches are preserved under the tracks and accessible from the Malá Amerika warehouse, others are visible in Nové Sady Street.
The international panel evaluated a total of 46 portfolios, as the review revealed that one request to participate was duplicated. The participation was also confirmed by the three studios invited in advance. The international urban-transport-architectural competition for the design of the New Brno Main Train Station was announced on 31 August 2020. The joint contracting authorities are the City of Brno and the Railway Administration. It is a two-phase restricted competition. This format allows the contracting authority to reduce the number of participants based on portfolios and reference projects only to those who are most suitable for the competition, which then receive sketch fees for processing the proposal.
In the first phase, twelve competitors will partially prepare their competition proposals and four of them will be selected to participate in the second phase of the competition. In the second phase, the four selected participants will prepare a more detailed version of their proposals, the panel will select the winner and determine the order in the second, third and fourth place. The evaluation of proposals in the first phase will take place in early March; the second phase evaluation will take place in June 2021. The winner will participate in the elaboration of subsequent project documentation.
The competitors will be tasked with designing the station building, including the roof and the platforms, the layout of the interior and the location of the main station hall, as well as the complete solution of adjacent public spaces, including administration buildings, housing and public amenities. It is also necessary to solve the form and location of the bus station, urban public transport terminal, parking, bicycle storage or pedestrian connection. The representatives of the city and the region decided in 2018 that the new station will stand by the river on the site of today’s lower station.
