Extension of Uster Hospital: Soil surveys and monitoring of soil displacement process

The project

Location: Uster (ZH)
Customer: Uster Hospital
Phases: -
Duration: 2019-2020
Building costs: approx. CHF 350,000,000


Uster Hospital is being converted and extended in several phases. Some of the new buildings will be accommodated in the present parking lot and a lawn is being temporarily used for installations and temporary parking. Some of these areas have been entered in the test perimeters for soil displacement (PBV). Thus samples of the topsoil and subsoil were taken from various parts and analysed for the relevant contaminants. In addition, invasive neophytes on the site were collected and mapped. These measures were used to ensure appropriate processing of the displaced soil during construction work.


Our services

  • Assessment and testing of general suspected contamination by evaluating GIS maps and aerial photographs
  • Development of a representative survey concept for the phased building works
  • Planning and execution of a sampling campaign
  • Collection and mapping of invasive neophytes within the project perimeters
  • Evaluation of the findings and results, evaluation of soil contamination in accordance with the VBBo and VVEA regarding use and disposal
  • Issuing of soil displacement forms for the planning application
  • Monitoring of soil removal and the soil displacement process


  • Representative sampling in the small parking lot
  • Very restricted space for intermediate storage and use of the displaced soil on site
