Education cluster Polyfeld Muttenz

At the cantonal school site Kriegacker in Muttenz, a new focus location for vocational education is being created with the first stage of the Polyfeld secondary school campus. The Baselland Vocational Training Center will receive a comprehensively renovated tower, a new workshop building, a triple sports hall and an auditorium-cafeteria.

The canton of Basel-Landschaft is combining the BBZ BL, the Muttenz grammar school and the Zentrum für Brückenangebote into a joint secondary II campus at Polyfeld. Stage 1 focuses on the dismantling and conversion of the existing tower, which has been gutted from top to bottom, decontaminated and completely dismantled in the core area. The core walls, staircases, floor slab and foundations were removed in a controlled manner over an area of around 20 by 20 meters.

To ensure that the slender tower remained stable during the conversion and new construction, temporary bracing with heavy steel frames was installed on each floor. At the same time, the new construction of the building core and the construction of the new main staircase, which is to become a design center of the BBZ as a freely suspended prefabricated construction in exposed concrete, began.

Exposed concrete, workshop building and triple sports hall
All new buildings in stage 1 will be constructed in high-quality exposed concrete, with a project-specific formwork and concreting concept for uniform surfaces. The workshop building, which is around 55 meters long and 26 meters wide, is being built in three stages so that walls, columns, earthquake walls and ceilings can be constructed in parallel on each floor.

The new triple sports hall will have a complex supporting structure made of pre-stressed prestressed concrete beams, which will be assembled in stages, provisionally supported and pre-stressed after the ceiling has been concreted. This allows the hall to be flexibly divided into three smaller units at a later date. An external spiral staircase with specially developed formwork provides an architectural accent. The adjoining assembly hall and canteen is a prefabricated construction, combining exposed concrete with a composite timber ceiling and functionally linking the different parts of the building.

Life science training building in the Polyfeld
Parallel to the cantonal campus project, the Polyfeld is being given an additional focus with a new life science training center. The Basel district council has approved a contribution of around two million francs for this. Around CHF 1.7 million for the construction of the new training location at Birsfelderstrasse 46 and around CHF 390,000 for special laboratory equipment. The new building will have a net floor area of around 19,500 square meters. Cantonal funding will be provided for an eligible floor space of around 1,400 square meters.

The project is sponsored by the Aprentas training association, which intends to combine its existing locations on Lachmattstrasse and in Schweizerhalle in the new building. Aprentas, which originally emerged from the Novartis environment, offers inter-company courses for EFZ training in chemistry, biology and chemical and pharmaceutical technology. The cantonal funding strengthens Muttenz as a life science training location and complements the Polyfeld secondary school campus with a clearly profiled, practice-oriented training infrastructure for regional industry.
