 I.4) The application documents must be sent to the following address:



II.1.1) Title of the competition issued by the client 

An open application procedure for working groups consisting of one or more architects, open space planners, structural engineering offices and supply technology engineering offices (insofar as these tasks are not the core competency of the office) from the EEA member states and Switzerland for a subsequent single-stage, restricted design competition in an anonymous procedure based on the general principles of the OAI (the general principles of the organization of architectural tenders in the Grand Duchy of Luxembourg). 

II.2.2) Description

Overall, the urban district of Belval is divided into four development modules, the Cité des sciences with its restored, imposing backdrop of smelting furnaces, the Square Mile, the Park Belval and the Belval residential quarter.

The subject of the planned competition is the redesign and revitalisation of the two former sinter basins on the Central Square, the central space in the future Square Mile quarter.

The sinter basins were built in the 1970s and were used to prepare the coal residues before they were taken to the smelting furnace. Today, all that remains of the site are the concrete structures and some steel installations. The basins have diameters of up to 40 m and a maximum depth of approx. 12 m in relation to the car parking area that currently borders them. The total area of the sinter basin square to be designed is approx. 6,730 m² (up to the edges of the planned surrounding buildings). The site consists of several operating levels and is also permeated with passages, galleries and ancillary spaces.

As part of the development of the quarter, the intention is to restore a useful purpose to the former sinter basins. This should be in harmony with the mixed areas of use (offices, trade and residential) of the surrounding buildings currently in the concept design phase.

The product of the project competition will be an expressive, timeless design which will blend in with the overall concept for the quarter, and which will form the beating heart of the quarter due to its attractiveness and unique nature.

In general, the tenderer is pursuing the following goals with the project:

·       The creation of a unique, vibrant square that invites visitors and residents to use it all year round.

·       Incorporation of the different basin levels into the overall concept.

·       The creation of a reference to the area’s industrial past.

·       Integration into the overall architectural design of the quarter with its pedestrian streets and arcade walkways.

·       Development of a usage concept (e.g. sport, leisure, relaxation, culture, gastronomy, etc.) taking into account a potential phased usage of the site.

In order to achieve this goal, AGORA plans to issue for tender a single-stage, anonymous project competition with a preliminary application procedure and a restriction of the maximum number of participants to 7 teams. Through this invitation for applications, the aim is to find a planning team consisting of a combination of offices for architectural and open space planning, as well as structural engineering and supply technology offices for technical support.

II.1.3) Place of implementation:

Belval, Belvaux, Luxembourg


III.1) Eligibility for participation

All planning offices based in the EU or Switzerland are eligible to apply for the pre-selection procedure. Sufficient evidence of ability to perform professional services must be provided in the form of the entry in the commercial or professional register (or similar) and an authorization to present building documents (or the equivalent) in Luxembourg must be guaranteed. Evidence of this must be provided before any contract is awarded.

Should the applicant fail to provide this authorization, a cooperation must be entered into with a Luxembourg-based planning office which is in possession of the necessary authorization to present building documents.

The planning offices approved to take part in the project competition after the pre-selection procedure form a planning team. In this planning team, the participating architect's office takes the leading role and in addition, groups together the following members (if these tasks do not lie within the core competency of the leading architect’s office):

·       Office for open space planning

·       Structural engineering office

·       Supply technology engineering office

The formation of bidding consortia is permitted. Evidence of permission for all members to perform professional services in Luxembourg must also be provided if a contract is awarded.

Bidding consortia must act as a joint and severally liable working group and nominate an authorized representative. A binding declaration regarding the legal form, the authorized representative and the joint and several liability of all members must be submitted together with the application documents.

The entire project planning must be oriented to the legislation applicable in Luxembourg. A good knowledge of the administrative documents is required. The building owner requires the constant presence in Luxembourg of a professional representative of the project team to whom the contract is then awarded throughout the project implementation period.

Due to the complexity of the task, collaboration with an experienced structural engineering planner in the area of usage conversion/industrial monuments is required. Evidence of the technical feasibility of the design must be provided during the project competition phase.
