Renovering og utvidelse av flermannsboliger - Berninastrasse 85

Totalrenovering av åtte bygninger

The Allenmoosstrasse renovation project is centrally located in Oerlikon, close to Zurich. This extensive project involves the complete renovation of eight multi-occupancy homes, extension of the buildings, and refurbishment of an underground car park with 48 spaces. The buildings were taken back to their support structures, adjustments made to floor plans, and new lift systems were added alongside larger balcony recesses.

Generalkontrakt og trematerialer, CHF 21M

As the general contractor, Implenia managed the entire project, which included the refurbishment and extension of eight apartment buildings to high standards. The buildings now house 88 apartments and 48 underground parking spaces. Key construction elements featured wooden structures such as roof extensions, balcony enlargements, laminated timber ceilings, and cross-laminated timber walls. The total project cost was CHF 21 million, with CHF 1.5 million attributed to wooden construction.

Utfordringer med byggetekniske forskjeller

One of the major challenges was developing the renovation concept in coordination with the building contractor. Technical clarifications were necessary due to dimensional differences in the existing structure, requiring comprehensive measurement concepts and integrative planning. Other challenges included maintaining utility lines, managing short construction timelines, handling site logistics in cramped spaces, and achieving a 100% occupancy rate before the end of construction.

Fokus på miljøvennlig bygging

Environmental sustainability was a focus in this project, with the building extension made from structural prefabricated wood elements and a framework structure. The project was successfully completed and significantly enhances the living conditions and functionality of the residential units.
