Progress with slope stabilisation in Bergdietikon

Bergdietikon AG/Opfikon ZH, May 2024

After completing the slope stabilization in Land Rai, the municipality of Bergdietikon is conducting further measurements to ensure the buildability of the area. Due to heavy rainfall during the observation phase, geologists have decided to collect additional data. Six core drillings and six piezometer drillings for pressure measurement are to provide further clarity. The results of these investigations will determine the future development of the site.

Following the completion of slope stabilisation measures in Land Rai, the municipality of Bergdietikon has arranged for measurements to be taken. These are intended to ensure that the site can be built on. Due to heavy and persistent rainfall during the observation phase, two independent geologists decided to collect further measurement data. In May 2022, Implenia Schweiz AG began dewatering work on the slope and stabilisation measures in close cooperation with the municipality. The monitoring phase then began.

According to a press release, the heavy rainfall led to meaningful measurement data. Although no critical values were measured at the measuring points of the neighbouring buildings, the geologists were not yet able to make a conclusive assessment of the buildability of the slope based on the measurement data collected. Further data would therefore be collected in consultation with the cantonal specialist centre. Six core drillings will be carried out from 21 May. In the northern part of the site, six piezometric boreholes will also be drilled to measure the pressure. These will be carried out by the company Geocontrol from Rumlikon ZH.

A design plan was adopted by Bergdietikon municipal council on 23 November 2020 and approved by the canton on 26 February 2021. If buildability can be guaranteed, the Rai land will be developed. The developer will then be Implenia Schweiz AG, which would like to realise several residential buildings there based on the guideline project from 2019.
