300m and 400m bullet traps Neuholz shooting range, Wald
Remediation of contaminated sites incl. preparation of a planning application dossier
The project
Place: Wald (ZH)
Client: Municipality of Wald (ZH)
Phases: Project planning, submission, remediation of contaminated sites
Duration: 2018-2020
The Neuholz shooting range in Wald (ZH) comprises a 300 m bullet trap that is still in use and an old 400 m bullet trap that was used until around 1930. Both bullet traps are located several hundred meters from the nearest road. Economic access and construction site logistics posed a key challenge for the remediation of the two bullet traps.
As part of the remediation work, a total of almost 3,000 tons of heavily contaminated bullet trap material was removed and disposed of. After the remediation, the site was recultivated in line with the location and the 300 m bullet trap was converted to an emission-free bullet trap system.
Project planning for the remediation of contaminated sites incl. preparation of a planning application dossier
Preparation of tender documents and public invitation to tender for the remediation of contaminated sites
Preparations for construction and condition management with the involvement of the affected landowners, land managers and official bodies
Site management and specialist site management for the remediation of contaminated sites for the two bullet traps
Soil science construction supervision (BBB), coordination of recultivation and greening, regulation of subsequent management with the affected farmers
Challenges
Development and construction site logistics proved to be extremely challenging and required construction roads several hundred meters long and the crossing of a stream
Numerous affected landowners and land managers who were involved in the project planning at an early stage
Complex approval procedure with various special permits required
High water protection requirements and conditions in the approval process and during construction
Enormous quantities of heavily contaminated excavated material that had to be professionally triaged and disposed of
Large-scale and challenging recultivation in steep terrain
