Europe-wide award of planning and construction services for the new construction of the Weissenhof Visitor and Information Centre (BIZ) in Stuttgart
Coinciding with the 100th anniversary of the Weißenhof Estate, an icon of modernism, the International Building Exhibition (IBA) 2027 will take place in Stuttgart and the region. The number of visitors to the Weissenhof Museum has already risen significantly since the two Le Corbusier buildings were inscribed on the UNESCO World Heritage List in 2016.
The IBA27 Stuttgart region expects at least 1 million visitors for its presentation year 2027, of which an estimated 250,000 visitors are expected for the Weißenhofsiedlung. Without supplementing the existing museum operations, these visitor numbers cannot be managed and cared for. Against this background, the state capital Stuttgart intends to create an innovative, multifunctional visitor and information center.
How can a building be designed and constructed that continues the pioneering ideas of modernity, but which claims to find a permanently valid form from the lessons of the past hundred years and the burning issues of the present? Resource issues, waste avoidance, climate neutrality play just as important a role as beauty, accessibility, appropriability and adaptability.
The BIS is intended to be both a starting point into the settlement and a point of orientation. The area between the State Academy of Fine Arts and the Weißenhof Estate has been chosen as a suitable location. The completed urban planning ideas competition Weissenhof 2027 has confirmed this location and set framework parameters for further processing.
The Weissenhof Visitor and Information Centre (BIZ) in conjunction with the new square space to be created is intended to serve as a connecting element between the Weißenhof Estate and the Academy Campus and to rearrange the entrance situation of the State Academy of Fine Arts.
In the exhibition year of IBA27, it is intended to serve as a presentation venue and starting point for a visit to the Weißenhof Estate. The space program to be realized provides for around 1,225 m² of usable space, with the following uses to be accommodated: ticket sales, exhibition room, media room, shop, offices, gastronomy, sanitary facilities, cloakroom. There are about 815 m² for visitors, about 120 m² for visitor ancillary rooms (cloakroom, toilets, etc.) and about 290 m² for the administrative unit. Further information on the use and requirements for the space program can be found in the appendix "General specifications".
The project will be implemented within the framework of a Europe-wide combined tender competition for planning and construction services in a negotiated procedure in accordance with VOB/A, preceded by a Europe-wide participation competition using the "two-envelope procedure". The draft part ("Envelope 1") and the economic part ("Envelope 2") to be submitted anonymously will be evaluated separately in a step-by-step procedure. Only the indicative tenders whose draft part achieves the minimum number of points described in more detail in the tender documents will be subject to an initial economic assessment. If the minimum scores are achieved, the design part will be weighted at 60% and the economic part at 40%.
It is of particular importance that in the realisation of the Weissenhof Visitor and Information Centre (BIZ), great emphasis is placed on the greatest possible proportion of innovation as well as urban planning, architectural and functional quality accompanied by high energy efficiency. As a result, an innovative, high-quality building appropriate to the building task is to be created, whereby the use of room modules is also possible.
The tender documents will contain provisions to the effect that the contracting authority may refrain from constructing the building if it is foreseeable at an early stage in the planning and approval phase that the construction work cannot be carried out on the completion date.
The applicants selected in the context of the participation competition will receive more detailed information on the subject of the order by requesting an offer. In this context, it is pointed out that planning proposals have to be worked out as part of the offer phase.
