INTERNATIONAL OPEN PUBLIC COMPETITION FOR THE CONCEPTUAL DESIGN OF THE BRIDGE IN DOLAC NEIGHBORHOOD IN THE CITY OF BANJA LUKA (PP No 03-404-313/19)

In order to obtain the appropriate architectural design of the bridge across the river Vrbas in position of the special cultural, historical and ambient importance for Banja Luka (named “Settlement Dolac”), and to get quality concepts and conceptual solutions for planning and activating Urban zones in the immediate surroundings of the bridge, the city of Banja Luka is announcing the OPEN, INTERNATIONAL COMPETITION FOR THE ARCHITECTURAL DESIGN OF THE BRIDGE IN THE DOLAC SETTLEMENT IN THE CITY OF BANJA LUKA

Like any river, the river Vrbas connects and separates; like any river, it has two faces – the generous and pleasant one, which benefits the human community even without investing in the river, and the frightening one, when its force turns against this community. Both faces are reflected on the human need to cross it, to connect its banks for his benefit in his coexistence with the river… to establish one of the basic forms of his relationship to the river – crossing over.

Bridge is the intersection of this relationship…

A bridge over the river Vrbas in the village of Dolac, near Banja Luka fortress Kastel, will upgrade the townscape of the inner city center. The well-known scene of the fortress will become even better known with the presence of a bridge… from a star townscape, it will become by force of its importance and meaning – a superstar – a townscape for the future.

Questions and answers

Is it possible to get a longitudinal profile of the road, as well as the defined lower edge of the bridge construction in relation to the river Vrbas? It is necessary for the positioning of the bridge and for the layout of construction support sites.

Competitors can find definition of the level of the lowest bridge element in Folder “2_COMPETITION_PROGRAM_AND_REQUIREMENTS”, page 24, Competition Task.

In folder “3_3_SPATIAL_PLANNING_AND_TECHNICAL_REQUIREMENTS_EXCERPT”, competitors can find spatial constraints, i.e. the obligatory elevation angle at the crossing of Đure Daničić St. and Carica Milica St. with the access roads to the bridge. The definition of the final longitudinal profile and the constructive proposal of the bridge is the task of the competition with the respect of the mentioned elevation angle.

Where can we download tender documentation in English or Latin?

Competition documentation in English is available for the applicants via link http://en.banjaluka.rs.ba/wp-content/uploads/arhitektonski_konkursi/bl_bridge_dolac_competition_documentation.zip

In the document COMPETITION ANNOUNCEMENT, under the 2.3.4. Graphic Attachments part it is stated that the content of the required competition documentation includes six 3D visualisations (9.1.-9.6.) and a 3D animation. However, in the graphic poster layout there is only four of these 3D visualisations (9.1.-9.4.). What does that mean - are the last two optional or? Also, is the existance of 3D animation eliminatory, or is it possible to provide it later in case of winning the competition?

As stated in Chapter 2.3. CONTENTS OF THE REQUIRED COMPETITION DOCUMENTATION all participants are obliged to submit the following documentation: notebook with textual and graphic attachments, exibition poster, small poster for digital exibition, all graphic attachments (1-10) and 3D animation.
With regard to the graphic display of the template, participants can select four 3D views out of the six required, which, in their opinion, are the best illustrations of their solution/proposal.

I was wondering if you might consider modifying the requirement of providing 3D animation (for example by making it optional or obligatory only for winners). I am asking because this one element (if done properly) might take more time than the design process + preparing all the other drawings and renderings combined. 30-60 seconds animation requires making 720-1800 individual renderings and if outsourced its price can easily exceed 5-10.000 euro. Because of that, I am afraid that this requirement might discourage many of the potential participants.

As stated in Chapter 2.3. CONTENTS OF THE REQUIRED COMPETITION DOCUMENTATION all participants are obliged to submit 3D animation.

What is the length of the bridge?

As stated in COMPETITION PROGRAM AND REQUIREMENTS (folder 2), page 20:
“The task of the competition is architectural conceptualization of a bridge at the mouth of the river Crkvena in the river Vrbas, the exploration of possibilities for development of the public and green space under the bridge, as well as the general conceptualization of the form and fabric of the immediate urban surroundings. The concept implies basic geometry of the bridge, the number of spans and the proposed structural system.”
Lenght of the bridge will depend on the chosen concept.

Can the bridge be straight for some reason?

Bridge position is defined by SPATIAL PLANNING AND TECHNICAL REQUIREMENTS, foder 3.3 of Competition documentation.

How will he/she be able to address the question after 7th August 2019 if there are technical interferences or something unpredictable happen, because the deadline is too short for the conceptual design and I think it should be possible, ie. extend the deadline for questions?

Deadline for questions is defined in Competition announcement.

How could we get competition code (5 digits and 2 letters)? or is it intentionally named(coded) by the competitor?

А unique code consisting of five Arabic numbers and two letters is chosen by the competitor.

Is it possible a single competitor to submit more than one proposal?

Each applicant (competitor) is allowed to submit only one competition proposal without any variant solutions. (page 7., Competition announcement)

Is there any prize money?

Awards are defined in the chapter 6. (page 10., Competition announcement)

The need for questions will be after 07.08.2019. especially when the paper is submitted, now I have a question about the graphical representation of the template, does the participant choose the four 3d views and enter chosen graphical views in view 9.1 - view 9.2- view 9.3 and view 9.4 and where will participant enter the other six obligatory views, is it to be entered in the horizontal projection of the bridge 1: 500, longitudinal section 1: 1500, code, textual description up to 1000 characters, what is entered in the field situations 1: 1000 and what is entered in the place for the table and for such technical problems and ambiguities about submitting proposal and technical problems with filling would you allow questions until the end of the competition.

An integral part of the Competition documentation is the Competition announcement in which are defined the contents of the required competition documentation, as well as deadlines.

Is it possible to know which is the average level of the river water compared to the right and/or left bank? Moreover: do you need to guarantee river be navigable - i.e. do you need any particular vertical distance between river water and bridge deck to allow a boat to navigate through the river? If yes, could you clarify this measure? Thanks!

Deadline for questions is defined in the competition announcement (7th August 2019).
The competition task is available to competitors in the folder “2_COMPETITION_PROGRAM_AND_REQUIREMENTS”, where they can find the information on the lowest bridge element level. Note: Answers to similar questions can be found on the official website of the competition under „Questions and Answers“.
