300 m and 400 m bullet trap shooting range Neuholz, Wald

The project

Location: Wald (ZH)
Customer: Wald Municipality (ZH)
Phases: Project development, submission, site remediation
Duration: 2018-2020
Building costs: approximately CHF 1,000,000


The Neuholz in Wald (ZH) shooting range includes a 300 m bullet trap that is still in use, as well as an old 400 m bullet trap, which was used until around 1930. Both bullet traps are hundreds of metres away from the nearest street. For the contaminated site remediation of the two bullet traps, economic development and construction site logistics presented the major challenges.

As part of the contaminated site remediation, a total of almost 3,000 tonnes of heavily contaminated bullet trap material was removed and destroyed. After remediation, the terrain was recultivated in accordance with site requirements, and the 300 m bullet trap was converted to an emission-free bullet trap system.


Our services

  • Developing the remediation project for the contaminated site including preparing a planning application
  • Compiling submissions documentation and the public contamination remediation tender
  • Construction preparations and requirements management, taking into account the affected landowners, farmers and government authorities.
  • Contaminated site construction management and specialised management for the contaminated site remediation of the two bullet traps.
  • Pedological building management (PBM), coordination of recultivation and greening, regulation of subsequent cultivation with the affected farmers


  • Development and construction logistics proved to be extremely demanding and required construction tracks hundreds of metres long, as well as the crossing of a stream.
  • Numerous affected landowners and farmers were involved at an early stage of the project development.
  • Complex approval procedures with various special permits being required.
  • Stringent legal water protection requirements and conditions for the approval procedures and construction work.
  • Enormous amounts of heavily contaminated excavated material, which had to be professionally triaged and disposed of.
  • Large-scale and demanding recultivation in steep terrain.
