Letting you know where hazardous substances may be found

You are likely to find hazardous substances such as asbestos, polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PACs) or heavy metals in buildings constructed before 1990.

Generally speaking, these substances do not pose a health risk during ordinary use of the building. However, human health may be endangered if dismantling works are not carried out correctly. You are therefore duty bound to carry out a hazardous substance risk assessment before undertaking renovation or demolition works.

We provide comprehensive advice and guidance on building contaminants and when deciding when to perform certain investigations and when it is necessary to carry out decontamination. Our lawyers are available to advise you on legal issues relating to asbestos and other hazardous substances.

Our services:

  • Compiling reports on building contaminants (screening, building checks, pre-remediation investigations)
  • Drawing up project-specific decontamination plans for construction waste having regard to building contaminants (in accordance with the requirements of article 16 of the Ordinance on the Avoidance and the Disposal of Waste (ADWO)
  • Assistance when planning and carrying out asbestos decontamination work (specialist planning and construction management)
  • Implementing “independent monitoring” of building contaminants during renovation or demolition works in the Canton of Zurich
  • Determining the action required, providing clarity in questions of liability, assessing legal duties under public law, advising in respect of warranty claims in purchase agreements
