Renovering og utvidelse av flermannbolig - Webergutstrasse 4a

Full renovering av 40 leiligheter

Implenia was tasked with renovating the property at Parkstrasse 11 in Bern, which includes 40 apartments. The project encompassed comprehensive renovations such as the complete removal of all installations, windows, and door frames, as well as professional removal and disposal of asbestos-containing materials. Other works included the primary walling in kitchens and wet rooms, plus all plastering work inside the apartments. Notably, a new concrete staircase was constructed between the fifth and attic floors.

Mulighetsstudie og kostnadsestimat

Their Real Estate Consulting unit provided a feasibility certification for this project, which included a rough estimate of the costs to add an attic floor, aligning it with a neighboring building that had the same addition a few years prior. Furthermore, feasibility and cost estimates were provided for transforming recessed balconies and terrace areas into additional living spaces. This contributed to projecting the future returns generated from the added floor and expanded living areas.

Logistikk- og tidsplanutfordringer

The project faced several challenges, including cramped on-site conditions that allowed only one skip at a time. Rubble had to be sorted and stored inside the building before disposal, and access was facilitated via an external lift. The project operated on an extremely ambitious schedule, putting significant pressure on the workers, particularly during the demolition of the old lift passage, which was allocated just five days before applying the 280 m² concrete.

Hev 40 leiligheter-3.96 m CHF

The successful extension of the building enabled the addition of potential floor areas, meeting the client's strategic objectives. Remarkably, all 40 apartments were rented out swiftly upon project completion. The renovation project had a construction volume valued at 3.96 million CHF, 4.2 million EUR, 3.5 million GBP, 49.3 million NOK, 48.2 million SEK, and 4.4 million USD, with costs converted based on average yearly exchange rates during the project's realization. Implenia Schweiz AG served as the architect for the project.
