QuestionDear Sir, Is it required within the Competition Solution to elaborate architectural shaping of ventilation openings, including protection against atmospheric exposure (rain, snow and surface water) or it may be assumed that their final technical solution will be defined in further design phase in compliance with the requirements of the metro station system?

Answer  Dear Sir, In the Competition Program, Chapter 6.4 PROGRAM REQUIREMENTS, Item 3) Free and Green Areas, it is specified:

“Emergency openings should be planned at the ground level, while grids of ventilation openings may be planned at the ground level or at a certain height (maximum 3m) if they are an integral part of the concept of square landscaping (e.g. within benches, planters, artistic installations and alike).”

Burial of ventilation and emergency openings is not permitted. Due to technical, safety and exploitation requirements, openings are executed at the ground level (+-0,00), with possible exemptions in some specific cases, such as fire requirements. Their minimum elevation above the finished ground level is planned, thus providing protection against surface water and impurities, with minimization of visual impact in the space. During following design phases all specified elements are subject to compliance with technical, safety and exploitation requirements. The selected Competition Solution will be conceptually further developed and adjusted through detailed design elaboration in accordance with the final solution of the station and its technical defining.

QuestionDear Sir, Is there a possibility of extending the deadline for submission of Competition Designs, taking into account the scope and complexity of the Competition Brief? Thanking you in advance for your answer. .

Answer Dear Sir, In accordance with the Article 45 of the Rulebook on the Manner and Procedure for Announcing and Conducting an Urban and Architectural Competition (Official Gazette of RS, No. 31/15), at this moment there is no possibility to extend the deadline for submission of Competition Designs.

QuestionIn the Competition Program ventilation and emergency openings are specified as fixed elements of the metro station, but their height relative to the surrounding terrain is not defined. Please clarify whether it is allowed to design ventilation openings integrated into the landscaping (at the level of pedestrian and green areas), subject to fulfillment of all technical requirements for ventilation, or whether it is mandatory that they be raised above ground level (e.g. approx. 45 cm).

AnswerDear Sir, In the Competition Program, Chapter 6.4 PROGRAM REQUIREMENTS, Item 3) Free and Green Areas, it is specified:

“Emergency openings should be planned at the ground level, while grids of ventilation openings may be planned at the ground level or at a certain height (maximum 3m) if they are an integral part of the concept of square landscaping (e.g. within benches, planters, artistic installations and alike).”

Question Is it possible to make a slight change of the fire escape route? In the existing position it does not fit in the concept of my solution, and I would like to know whether there is a possibility of its adjustment, subject to fulfilment of all prescribed requirements
Is it possible to design fire escape route as a multipurpose communication, i.e. in everyday use to function as a bicycle or pedestrian-bicycle path, whereas in case of need it would enable unhindered access for fire-fighting vehicles?
Is canopy mandatory or we can remove it considering that it does not fit in my concept which requires the railway station to breathe

Answer  Dear Sir, The fire escape route presented in the extract of the Preliminary Design of Savski Trg Metro Station (EGIS RAIL, 2024) represents a proposal of the fire escape route, given as one of possible spatial and functional concepts of the space concerned.

The rules of development and construction relating to the access of fire-fighting vehicles and the corresponding requirements are defined in the Competition Program in Chapter 6.4 PROGRAM REQUIREMENTS, Item 4) TRAFFIC SOLUTION – ACCESSES AND COMMUNICATIONS.

The said chapter defines that access for fire-fighting vehicles may be provided from all perimeter streets and that the Competition Solution should reconsider the fire escape routes proposed by the available design documentation and, if necessary, propose new solutions in compliance with the effective legal regulations for the purpose of avoiding any spatial conflicts and complying with the proposed spatial concept.

Please note that during elaboration of the fire escape routes it is necessary to provide compliance with all parameters and requirements defined in the Competition Program, as well as effective regulations, subject to taking into consideration relevant layout and leveling elements of the metro station, public use buildings and contact communications defined in the technical documentation contained in the Competition Documentation, in order for the proposed solution to be functional, technically feasible and adequately integrated into the spatial matrix of the square.

As regards the canopy of the Old Railway Station in Chapter 6.4 PROGRAM REQUIREMENTS, Item 2) Spatial Organization and Contents there is the following requirement:

“Canopy of the Old Railway Station (Historical Museum of Serbia) along the façade of the main body towards the square should be integrated into the planned contents of the square.”

Question Is it allowed to use fire escape route also as a bicycle or pedestrian-bicycle path, taking into consideration that it is not in permanent function for interventions? Of course, it is understood that its dimensions, bearing capacity and passability would remain completely compliant with the requirements for access of fire-fighting vehicles.

Answer  Dear Sir, In the Article 7 of the Law on Road Traffic Safety (Official Gazette of RS, Nos 41/2009, 53/2010, 101/2011, 32/2013 – decision of Constitutional Court, 55/2014, 96/2015 – other law, 9/2016 – decision of Constitutional Court, 24/2018, 41/2018, 41/2018 – other law, 87/2018, 23/2019, 128/2020 – other law, 76/2023 and 19/2025) given are the definitions of bicycle path and pedestrian-bicycle path:

bicycle path is the road designated exclusively for movement of bicycles and light electric vehicles,
pedestrian-bicycle path is a road intended for movement of pedestrians, bicycles and light electric vehicles.
In line with the above, it is not allowed to overlap fire escape routes with bicycle and pedestrian-bicycle path.

Question Is it possible to make a slight change of the fire escape route? In the existing position it does not fit in the concept of my solution, and I would like to know whether there is a possibility of its adjustment, subject to fulfilment of all prescribed requirements

Answer Dear Sir, The fire escape route presented in the extract of the Preliminary Design of Savski Trg Metro Station (EGIS RAIL, 2024) represents a proposal of the fire escape route, given as one of possible spatial and functional concepts of the space concerned.
The rules for development and construction relating to the access of fire-fighting vehicles and the corresponding requirements are defined in the Competition Program in Chapter 6.4 PROGRAM REQUIREMENTS, Item 4) TRAFFIC SOLUTION – ACCESSES AND COMMUNICATIONS.

The said chapter defines that access for fire-fighting vehicles may be provided from all perimeter streets and that the Competition Solution should reconsider the fire escape routes proposed by the available design documentation and, if necessary, propose new solutions in compliance with the effective legal regulations for the purpose of avoiding any spatial conflicts and complying with the proposed spatial concept.

Please note that during elaboration of the fire escape routes it is necessary to ensure compliance with all parameters and requirements defined in the Competition Program, as well as effective regulations, subject to taking into consideration relevant layout and leveling elements of the metro station, public use buildings and contact communications defined in the technical documentation contained in the Competition Documentation, in order for the proposed solution to be functional, technically feasible and adequately integrated into the spatial matrix of the square.

Question Has number of pages of the A Booklet been prescribed or recommended? How many 2D graphic attachments are to be submitted? How many 3D views (renders) is planned or recommended? Is preparation and submission of animation mandatory or optional? Are there recommended or mandatory scales for the layout, plan, sections and other graphic attachments? Is it possible without section, if there is nothing to be seen?

Answer Dear Sir, Chapter 8.3 CONTENTS OF COMPETITION ENTRY PACKAGE precisely defines the documentation to be submitted within the Competition Entry Package. Item 2) Graphic Attachments 2D and 3D defines mandatory graphic attachments and their scale.

The Competition Program prescribes one mandatory 3D view from the direction of the street SAO 4 (Kraljice Drage Obrenović) and others at the competitor’s option.

It is recommended to select the most representative views representing the concept of the Competition Solution in a clear and comprehensive way.

Also, Item 1) Booklet with Textual Explanation and Graphic Attachments prescribes contents of the Booklet, but neither optimal nor maximum number of pages has been prescribed.

Question I would appreciate a clarification regarding the Competition Documentation. Could you, please, specify which graphic attachments are mandatory for submission? Specifically, are sections and details a mandatory part of the Competition Entry Package or the authors are free to adjust the method of their presentation to the concept of their Design, with clear presentation of the solution through layout, diagrams, render views and textual explanation?
Also, has a provisional scope of the Competition Entry Package, i.e. maximum or recommended number of pages of A3 Booklet been prescribed or recommended?
Finally, please clarify is there a recommended or mandatory scale for the layout, plan and other graphic attachments, or the authors are free to select the scales representing their design in the best way.

Thanking you in advance for your answer.

AnswerDear Sir, Chapter 8.3 CONTENTS OF COMPETITION ENTRY PACKAGE precisely defines the documentation to be submitted within the Competition Entry Package.

Item 2) Graphic Attachments 2D and 3D defines mandatory graphic attachments and their scale.

Also, Item 1) Booklet with Textual Explanation and Graphic Attachments prescribes contents of the Booklet, but neither optimal nor maximum number of pages has been prescribed.

Question8.3 Subparagraph (2): What is the specific level of detail required for the graphic attachments (2D and 3D) including documents such as “Site plan, Landscaping composition plan, plan of the ground-level area with all landscaping features, Characteristic sections/elevations of the square”? (Is this conceptual design detail or construction drawing detail?) Must these B1 drawings be prepared using CAD or Revit software? Are renderings or color illustrations acceptable?

AnswerDear Sir, Mandatory graphic attachments should be prepared at the level of the competition urban-architectural and landscaping solution, i.e. at the level of conceptual design elaborated in detail, and not at the level of technical documentation for execution. The attachments must clearly present all elements specified in the Item 2 of Chapter 8.3 CONTENTS OF COMPETITION ENTRY PACKAGE, in the prescribed scales. 

The Competition Program doesn’t prescribe the program for preparation of graphic attachments. Participants may use CAD, Revit or other appropriate software, provided that the final attachments are submitted in the prescribed format and quality in accordance with the Competition Requirements.

Renders and illustrations of B1 format are allowed, but they represent a supplement and may not replace mandatory 2D graphic attachments specified in the Competition Program.

All elements and attachments of the Competition Entry Package specified in Chapter 8.3, represent mandatory parts of the Competition Design. Designs not containing the required elements and attachments will not be taken into consideration.

QuestionRegarding the green space requirement under Clause 5.1.3 (minimum 10% uncovered green surface): Could you clarify whether this quota applies exclusively to green areas outside the underground metro station footprint, or if landscaped areas located above the metro zone (e.g., roof gardens/hardscape-integrated planting) are also eligible to be included in this 10% ratio?

AnswerDear Sir, In accordance with the provisions of the valid design documentation, which represents the binding ground for realization of the space concerned, the norm of minimum 10% green areas in direct contact with the soil relates exclusively to the areas outside the underground metro station footprint.
The said norm implies forming of green areas with full ecological functionality, enabling direct contact between vegetation and soil, infiltration of stormwater and planting of high and medium vegetation. For this reason, the greened areas formed above the structural slab of underground facilities cannot be counted into the prescribed minimum of 10% green areas in direct contact with the soil.

At the same time, it is possible to apply various technical solutions for greening above the underground facilities that may significantly contribute to improvement of ambient, ecological and visual qualities of the space. When planning them it is necessary to comply with the requirements and guidelines of relevant institutions, including the requirements of the PUC Belgrade Metro and Train, which define restrictions regarding the type and character of vegetation above the station box, and other requirements and guidelines contained in the Competition Documentation.

In the Competition Material, in the Folder 1 GRAPHIC DIGITAL BASEMAPS, subfolder 4 SPATIAL REQUIREMENTS, there is a graphic attachment within which the zone of mandatory high vegetation is marked, outside the underground metro station footprint, as a spatial guideline for implementation of the said binding norm.

QuestionRegarding Clause 8.3, item 2) Graphic attachments 2D and 3D, which mentions 3D views at the participant’s discretion: May we submit renderings that are identical to the JPG files requested under the Material for electronic exhibition section, or are we required to provide distinct visuals?
If distinct content is mandatory, could you please advise which type of visuals should be prioritized for the exhibition JPG files to best satisfy the competition submission criteria?

AnswerDear Sir, The Competition Program doesn’t prescribe that the electronic exhibition material must contain visuals different from those presented within graphic attachments. It is allowed to submit the same renders, provided that they are prepared specially in accordance with the requirements for electronic exhibition: in total five .jpg attachments, horizontal orientation, width 2000 px, in RGB system and resolution 150 PPI. It is recommended for this purpose to choose the most representative views that are in a clear and comprehensive way representing the concept of the Competition Solution. Material for electronic exhibition represents a separate submission format, but doesn’t require production of completely new views.

Question  Can you please clarify what these emergency elements at the square are representing? Do they refer to emergency staircases, elevators or some other technical infrastructure? I need this information in order to properly solve landscaping and arrangement of urban furniture.

Answer Dear Sir, Emergency openings represent openings of emergency staircases. 

Question  Are entrances into and exits from the metro station defined so to be oriented towards the outer perimeter of the location concerned, i.e. towards the nearby streets, or is it allowed to direct them towards the inside of the square/park in accordance with the proposed concept of development and organization of pedestrian flows?

Answer Dear Sir, As specified in the Competition Program, the design of Savski Trg metro station should be implemented in to the conceptual design of the square. Entrances into metro station and elevators will be made in accordance with the Architectural Branding Manual, which is an integral part of the said project.

Above-ground parts of the station represent fix elements in solving the square surface (entrances/exits, elevators, ventilation and emergency openings, etc.) and influence organization of the square contents.

The preliminary design of Savski Trg Metro Station (EGIS RAIL, 2024) was made for Savski Trg Metro Station. The Books of Architecture and Landscaping, as well as the Architectural Branding Manual are an integral part of the Competition Documentation.

Question  Entrance into metro station Is it planned to make entrances into metro station exclusively as open staircase recesses on the ground level, or is there a possibility to design canopies or other covered elements above the entrance?

Position of elevator at the right entrance into metro

Is it acceptable at the right entrance into the metro station, in the zone of the planned school, to position the elevator on the opposite side relative to the side presented in the delivered design documentation, if such a solution enables more logical organization of pedestrian flows and better functional connection with the surrounding?

Level of processing of structures in the surrounding

For the needs of the competition entry package is it sufficient to present the structures in the immediate surrounding in a simplified manner, as the basic volumes (cubi), or a detailed architectural elaboration of their appearance is expected?

Character of central public space

Does the Competition Brief mandate forming of clearly defined central square as a space for gathering, or is it acceptable to organize the concept predominantly as a park-like space with greater participation of green surfaces and smaller, dispersed places for stay and gathering?

Thank you in advance for your answers.

Answer Dear Sir, As specified in the Competition Program, the design of Savski Trg metro station should be implemented in to the conceptual design of the square. Entrances into metro station and elevators will be made in accordance with the Architectural Branding Manual, which is an integral part of the said project.

Above-ground parts of the station represent fix elements in solving the square surface (entrances/exits, elevators, ventilation and emergency openings, etc.) and influence organization of the square contents.

The preliminary design of Savski Trg Metro Station (EGIS RAIL, 2024) was made for Savski Trg Metro Station. The Books of Architecture and Landscaping, as well as the Architectural Branding Manual are an integral part of the Competition Documentation.

The Competition Brief does not define the level of detail of presentation of the structures in the immediate surrounding. Participants are free to adapt the manner and level of their elaboration to their own concept and the manner of presenting the competition solution.

The Competition Brief did not define in advance the exclusive model of space organization, bearing in mind that the location concerned should simultaneously respond to more different, mutually complementary functional and ambient requirements. Program requirements define the need of forming different ambient units for stay, rest and movement of users, providing at the same time a unique functioning of the space and its adaptability to intensive use, taking into consideration the cultural-historical significance of the location and its role of a common holding area of the public use buildings and metro system stations. The said requirements are not mutually exclusive, but are viewed as mutually complementary aspects of a unique spatial concept.

Precisely the participants are those from whom it is expected, through an authorial approach, to offer an original response to the complexity and multiple meanings of the space concerned, unifying the defined program, functional and ambient requirements into a single and recognizable spatial concept.

Question  Does the competition imply forming of a central square for larger public gatherings, or is it acceptable that the solution focuses on park-like character of the space, movement and a series of smaller ambiences for lingering?

Answer Dear Sir, The Competition Brief did not define in advance the exclusive model of space organization, bearing in mind that the location concerned should simultaneously respond to more different, mutually complementary functional and ambient requirements. Program requirements define the need of forming different ambient units for stay, rest and movement of users, providing at the same time a unique functioning of the space and its adaptability to intensive use, taking into consideration the cultural-historical significance of the location and its role of a common holding area of the public use buildings and metro system stations.

Precisely the participants are those from whom it is expected, through an authorial approach, to offer an original response to the complexity and multiple meanings of the space concerned, unifying the defined program, functional and ambient requirements into a single and recognizable spatial concept.

Question  Savski Square Is it necessary, in the layout drawing, to present Savski Square in accordance with the existing, as built solution, or is it sufficient to roughly indicate it (e.g. using radial paths) to create a connection with our design, bearing in mind that the square will be seen in the drawings anyway?

Sections

Are sections mandatory part of the submission? Considering that the terrain is almost completely flat and not having any more significant differences in elevation, I wonder whether in this case they have sufficient informative value.

Design sustainability

Will aspect of design sustainability be evaluated during assessment? If yes, does sustainability imply exclusively technical and environmental aspects (materials, water management, energy efficiency, etc.), or social and emotional sustainability of the space, i.e. its capacity in a long run to create high-quality experience and connection of users with the place will be also evaluated?

Answer Dear Sir, The executed parts of Savski Square need to be presented in the layout plan in the scope required for clear perceiving of spatial, functional and leveling connections between the existing and newly designed space. This particularly implies the parts of the existing development with which the competition solution is directly connecting, i.e. the surfaces, plateaus, ramps, staircases and other elements necessary for clear perception of the spatial, functional and levelling integration of the existing (executed) and the part of the square being the subject of competition elaboration.

Chapter 8.3. CONTENTS OF COMPETITION ENTRY PACKAGE prescribes that the competitors are required to submit characteristic sections and/or elevations of the square in adequate scale.

Although this terrain is predominantly flat, the said attachments represent an important instrument for perceiving spatial, functional and leveling relationships, as well as relationships between the landscaping elements in real scale because of which 3D views cannot replace them completely.

It is up to the author, in compliance with the character of the solution, to determine the type and position of characteristic sections and/or elevations with which he/she will most completely represent his/her spatial concept.

Competition material does not specifically define the notions of social and emotional sustainability of space. However, the requirements relating to affirmation of identity of place, quality of ambience, evaluation of the historic, cultural and sociological context, as well as creation of a recognizable public space, indicate that sustainability is not perceived exclusively through technical and environmental aspects, but also through ability of the proposed solution to contribute to the quality of the space and experience of its users in the long run.

Question  Is it necessary to present the part of Savski Square in front of the Old Railway Station, which has already been completed, in 3D model and renders completely identically to the as built condition, or minor deviations in the modeling are allowed, taking into account that the detailed design documentation is not available to participants? Is it allowed to use tools based on artificial intelligence for the post-processing of renders, provided that the spatial solution, 3D model and architectural concept are fully authorial and made by the author of the Competition Design.

Answer Dear Sir, Considering the spatial scope of the Competition and the documentation available to participants, minor deviations are allowed in modelling and graphic presentation of the executed part of Savski Square in front of the former Main Railway Station (Historical Museum of Serbia).

At the same time, presentation of the as build condition needs to be sufficiently faithful to enable perceiving the relationship between the existing and newly designed space, and also proper understanding of the authorial concept, functional integration and ambient assimilation of the competition solution into the existing spatial context.

Please note that the competition material represents a set of input data based on which competition solutions are prepared and evaluated.

The Competition Program does not prescribe any limitation as regards the use of tools for production and graphic processing of competition attachments. Consequently, it is allowed to use AI tools in the phase of visualization and post-production of renders, provided that the spatial solution, architectural concept and three-dimensional model represent authorial design of the participant.

It is also necessary that graphic presentations truthfully represent the proposed solution and not to be misleading as regards spatial, functional, form-related or technical characteristics of the Competition Design.

The applied tools and visualization techniques may contribute to perceive the author’s solution more clearly, whereas evaluation of Competition Designs is based on the quality of the offered solution and its compliance with the Competition Brief, irrespective of the used presentation tools.

Question  Good morning! The point 5.1.2 of text of the program specifies: “It is permitted to install a smaller prefab building as a tourist info point (with maximum surface area of 4 m²)”. However, in the document “3­_Secretariat for Transport.pdf”, point 21, it is indicated that it is required to plan 2 pavilions with dimensions 5x4x2.75 m for the bicycle rental station. Please clarify whether it is forbidden to install structures larger than 4m² only in some specific zone? Or is it required to plan a space exclusively for the bicycle rental station, while the pavilion itself will be designed by the Secretariat for Transport?

Answer Dear Sir,

The paragraph “It is permitted to install a smaller prefab building as a tourist info point (with maximum surface area of 4 m2)” in the subparagraph 5.1.2 of the Rules for Developing Free and Green Spaces is given as a planning requirement taken from the applicable Spatial Plan for the Special Purpose Area of Development of Part of Riverside Area of the City of Belgrade – the Riverside Area of the River Sava for the Belgrade Waterfront Project (Official Gazette of RS, Nos. 7/15, 48/22 and 86/25). This provision relates to a possibility and not an obligation to install a prefab building intended for provision of tourist information to the users of the space in question.

On the other hand, the requirements of the Secreatariat for Transport are attached to the Competition Program documentation specifying that it is necessary to reserve a space for insallation of the public bicycle rental station, i.e. two locations with minimum dimensions 5 x 4 m with vertical clearance of 2.75m, where such space may be on one or two locations, depending on the spatial possibilities, in accordance with the Plan of Locations for Installing Bicycle Rental Stations in the Territory of the City of Belgrade (Official Gazette of the City of Belgrade, No. 121/21) – Location No. 66.

Chapter 6.4 Program Requirements, point 4) Traffic Solutions – Accesses and Communications of the Competition Program specifies the requirements for defining microlocation(s) tor insatalling the public bicycle rental station, consisting of elements of urban furniture and accompanying technical equipment. It is not planned to install a prefab building in the function of the public bicycle rental station, but to provide a space with adequate dimensions and its adequate functional, leveling and organizational integration into the spatial matrix of the square.

When determining the microlocation(s) it is necessary to take into account a wider context of the space, directions of dominant pedestrian movements and to ensure continuity of the existing and planned bicycle flows in the area concerned, subject to fulfilment of the other program requirements defined by the Competition.

Based on all above mentioned, reserving the space for the public bicycle rental station represents a mandatory program requirement of the Competition, whereas installation of the tourist info point is not mandatory and remains in the domain of author’s estimate of competition entrants.

Question  Good afternoon. Could you please advise whether registration on the competition website is required in order to participate?

Answer Dear Sir, Registration on the website is not required for participation in the Competition. Each competitor who downloaded the Competition Documentation acquires the right to participate in the Competition.

Question  Can you provide 3d model? Or we have ourselves to model it based on autocad?

Answer    Dear Sir, Because of copyright protection and limitations regarding sharing the copyright material, it is not possible to provide to the competitors the generated 3D models of the surrounding structures, including buildings of station, post office, transformer substation and school. Additional photos taken from a drone are available for the needs of photo editing within the Competition Documentation, in the folder 5_PHOTO AND VIDEO DOCUMENTATION. In addition, available renders which may be used for photo editing can be found within the same folder, in a separate subfolder named 3_Renders.

Question  When analyzing the competition documentation, we noticed certain discrepancies between the delivered CAD material and visual representations that are an integral part of the competition material. Namely, in the perspective and layout views (attached) the space behind the building of the former Main Railway Station, along the circular street, is treated differently related to the geometry and organization of the space resulting from the delivered CAD model. That is why it not completely clear to us which view is relevant and the adopted planning solution the Competition Design should be based on.

 Please clarify:

 Which material has the priority in case of inconsistency between CAD basemap and visual/display materials of the Competition? I am sending the link with the photo of the structures behind the Railway Station forming a semi-circular plateau    

https://www.gradnja.rs/savski-trg-saobracaj-spomenik-stefanu-nemanji/

Answer   Dear Sir, The relevant graphic attachments for preparing the Competition Design are in the folder I GRAPHIC DIGITAL BASEMAPS. They are adjusted with the planning basis for construction on the competition site, i.e. with the Spatial Plan for the Special Purpose Area of Development of Part of Riverside Area of the City of Belgrade – the Riverside Area of the River Sava for the Belgrade Waterfront Project (Official Gazette of RS, Nos. 7/15, 48/22 and 86/25), General Regulation Plan of Rail Systems in Belgrade with the Elements of Detailed Elaboration for Phase I the First Line of Metro System (Official Gazette of the City of Belgrade, No. 102/21) and General Regulation Plan of Rail Systems in Belgrade with the Elements of Detailed Elaboration of the Second Line of Metro System – Phase II (Official Gazette of the City of Belgrade, No. 104/25), as well as the guidelines of the relevant institutions.

Question Is the subject of the Competition Brief to make this space a continuation, in terms of design and concept, of the existing solutions of Savski Square in front of the Railway Station, i.e. to represent its spatial extension, or is it allowed to offer autonomous urban-landscaping solution with own identity, subject to observing all set functional and spatial requirements?

Answer  Dear Sir, The conceptual design of Savski Square, realized in the area in front of the building of the former Main Railway Station (Historical Museum of Serbia), is not a binding framework for competition solutions. With their conceptual designs of the square landscaping, the task of the competitors is to establish a correlation with the realized landscaping solution of Savski Square in front of the building of the Old Railway Station (Historical Museum of Serbia), and at the same time to create a unique identity of this part of the square.

Question Is it required that we previously apply for participation in order to get a code for submission of Competition Design, or the code is obtained in some other way? Can the same team of authors submit two different Competitions Designs?

Answer Dear Sir, In the Competition Program in the Chapter 8. Competition Rules_8.4 Technical Processing and Formatting of Competition Design it is specified that the unique code is selected by the author and that it must consist of two letters and five Arabic numbers. Each competitor participating in this Competition, either an individual or a group, has the right to participate in this Competition only with one Competition Design and within only one team.

Question Dear Sir, Please clarify whether the existing radial concept of Savski Square landscaping, realized in front of the building of the former Main Railway Station, is a binding framework for competition solutions, or is it allowed to propose its changes and widening of the concept if in such way a higher-quality and more comprehensive urban-architectural solution of the area within the scope of the competition is achieved?   Yours faithfully

Answer Dear Sir, The radial concept of Savski Square landscaping, realized in the area in front of the building of the former Main Railway Station (Historical Museum of Serbia), is not a binding framework for competition solutions.

With their conceptual designs of the square landscaping, the task of the competitors is to establish a correlation with the realized landscaping solution of Savski Square in front of the building of the Old Railway Station (Historical Museum of Serbia), and at the same time to create a unique identity of this part of the square.

Question Dear Sir, Is it possible to obtain technical descriptions of or requirements for the ventilation and emergency openings of the metro station? Are shaft houses planned? (the question refers both to ventilation and emergency openings)? Does the metro station solution allow (provide sufficient space) for the ventilation openings to be buried (at the same level as the ground level)?

Answer Dear Sir, Elaboration of technical description of the ventilation and emergency openings will be made in detail in the next design phase. Rules of development and construction of escape-ventilation shafts, as well as the related requirements, are defined in the text of the Competition Program in the Chapter 6.4 Program Requirements, Item 3) Free and Green Areas.  

Three above–ground structures are planned: two entrance station portals (Entrance A and Entrance B), and one smaller elevated cubic structure for the elevator. All other ventilation and emergency openings are solved at the level of the existing ground (at the levels +0.00, +0.20 and +0.45).

Burying of ventilation and emergency openings is not permitted. Because of technical, safety and exploitation requirements the openings are executed at the ground level (+-0.00), with possible exceptions in specific cases, such as firefighting requirements. Their minimum elevation above the developed ground level is planned (approximately +0,20 m to maximally +0,45 m), whereby protection against surface water and impurities is provided, with minimization of visual impact in the space.

During the following design phases all above mentioned elements are subject to adjustment to technical, safety and exploitation requirements. The selected competition solution will be conceptually further developed and adjusted through detailed design elaboration in accordance with the final solution of the station and its technical definition.

Question Is it possible to obtain dwg fire service access route, from the Figure 31 Savski Trg Metro Station – Landscaping Design?

Answer Dear Sir, The fire service access route, presented in the Figure 31 Savski Trg Metro Station – Landscaping Design in DWG format can be found on the page DOCUMENTATION, II GUIDELINES OF RELEVANT INSTITUTIONS in ZIP file to be downloaded from: https://www.savskitrg-konkurs.rs/dow/2_GUIDELINES%20OF%20COMPETENT%20INSTITUTIONS.zip
After downloading and unpacking the ZIP file, the requested file may be found on the following location: [1_PUC Belgrade Metro and Train/Exterior Design Project/2_Stanica Savski trg.dwg]

Question

1. Is it possible to obtain the Old Railway Station frontal photos of better quality, as a material for visualization?
2. Is it possible to obtain aerial drone photos, into which we could incorporate our solution?
3. Is it possible to obtain render from the Figure 12, or similar, to enable photo editing of our solution into the planned context?
4. Is it possible to obtain the basic model of the planned surrounding? roads, positions of greenery and volumes of structures?

Answer  Dear Sir, Additional photos taken from a drone, which can be used as the material for visualization and possible photo editing, have been subsequently posted within the Competition Documentation, in the folder 5_PHOTO AND VIDEO DOCUMENTATION. In addition, the available renders will be posted in the same folder, in a separate subfolder named 3_Renders.
As regards the basic 3D model of the planned surrounding, including roads, positions of greenery and volumes of structures, as well as generated 3D models of the surrounding structures – station, post office, transformer substation and school –  because of copyright protection and limitations regarding distribution of copyright material, it is not possible to provide the said models to the competitors. 

Question  Hello, I have noticed that there are some discrepancies between the positions of ventilation and emergency exits in the landscaping drawings of the metro station in the folder “2-GUIDELINES OF RELEVANT INSTITUTIONS” and the drawing “1_Spatial requirements”. At least two positions are shifted (it seems by mistake), thus please confirm which of these two documents is relevant?

Also, in the metro station landscaping drawing, ventilation and emergency exits are treated graphically in an identical way and they protrude 45cm related to the ground level. How are, in such case, functioning the emergency exits, as regards exits and evacuation?

Answer Dear Sir, After consultations and adjusting with the PUC Belgrade Metro and Train it was established that there is a technical error in the graphic documentation. The relevant and correct positions of the emergency and ventilation openings are presented in the graphic attachments in the folder II GUIDELINES OF RELEVANT INSTITUTIONS (Graphic Attachment 1_Master Plan in the folder 1_PUC Belgrade Metro and Train/Architectural Design in which ventilation and emergency openings are presented using different crosshatching).

Graphic attachments in the folder I GRAPHIC DIGITAL BASEMAPS have been adjusted meanwhile, and Information about Redownloading of Graphic Digital Basemaps posted on the site.

Rules of development and construction of escape-ventilation shafts, as well as the related requirements, are defined in the text of the Competition Program in the Chapter 6.4 Program Requirements, Item 3) Free and Green Areas.  Because of technical, safety and exploitation requirements the openings are executed at the ground level (+-0.00), with possible exceptions in specific cases, such as firefighting requirements. Their minimum elevation above the developed ground level is planned (approximately +0,20 m to maximally +0,45 m), whereby protection against surface water and impurities is provided, with minimization of visual impact in the space.

During the following design phases all above mentioned elements are subject to adjustment to technical, safety and exploitation requirements, whereby the selected competition solution will be conceptually further developed and adjusted through detailed design elaboration in accordance with the final solution of the station and its technical definition.

QuestionSear Sir, In the metro station landscaping drawing the “Pavement surface of fire service access routes” is drawn which is inconsistent with the ventilation exits.

1. Should the drawn fire service access route be used in the design? If yes, please provide clarification regarding discrepancies with the positions of ventilation exits that are +0,45m in relation to the ground level?
2. Should the design solution (generally) plan the fire service access route? If yes, what structures (positions) should it cover?

AnswerDear Sir, Fire service access route should be taken into consideration during preparation of the competition and/or conceptual solution.

In further elaboration of the design the positions of surface elements (vertical and horizontal) will be adjusted, inter alia, with the requirements of fire service accessibility.

Rules for defining the fire service access route are provided in the text of the Competition Program in the Chapter 6.4 Program Requirements, Item 4) Traffic Solution – Accesses and Communications.

Fire service access route should be viewed in the function of the access to the Historical Museum of Serbia and the Savski Trg Metro Station.

During further elaboration of the design, the positions of all surface elements – vertical and horizontal – will be adjusted with technical, safety, exploitation and firefighting requirements, as well as with the final technical solution of the metro station. In this sense, the selected competition solution will be conceptually further developed and adjusted through detailed design elaboration.

Question Dear Sir, Is it possible to obtain generated 3D models of the surrounding structures (buildings of station, post office, transformer substation and school) or perhaps aerial (drone) photos in high resolution to enable photo editing?
Answer Dear Sir, Because of copyright protection and limitations regarding sharing the copyright material, it is not possible to provide to the competitors the generated 3D models of the surrounding structures, including buildings of station, post office, transformer substation and school.

Additional photos taken from a drone will be subsequently posted for the needs of photo editing within the Competition Documentation, in the folder 5_PHOTO AND VIDEO DOCUMENTATION.

In addition, available renders which may be used for photo editing will be posted within the same folder, in a separate subfolder named 3_Renders.
