Demolition / Dismantling

When dismantling buildings, the aspect of building contaminants must be taken into consideration due to strict waste specifications. Not only industrially used buildings can contain hazardous materials, office and residential buildings have also been found to be problematic.

Unnecessarily high disposal costs are incurred if contaminated materials are mixed with unimpacted construction debris during dismantling. A systematic preliminary survey can avoid these additional costs.

Contaminant analyses of the building materials thus form the basis for detailed project planning and qualified bidding documents and ensure that there is no delay in the construction process due to contaminants and/or that the planned measures remain economically viable.

The particular challenges of “controlled” dismantling are, however, not restricted to the issue of hazardous materials. All waste that accumulates must be separated into identical materials insofar as possible. This necessitates meticulous planning of the dismantling process and the compilation of disposal concepts. Occupational safety and immission control, and ultimately also specifications for demolition technology, are part of the planning of the dismantling.

Our experience has shown that cost certainty during dismantling is based on three pillars:

  • qualified, thorough investigations
  • watertight bidding documents
  • rigorous construction supervision

On this basis we can offer our clients a time and cost-effective project management from a single source.

Our services to you include:

  • Technical investigation (collection and analysis of material samples)
  • Contaminant register
  • Dismantling concepts
  • Health and Safety Plans (A+S-Plans)
  • Recycling and disposal concepts
  • Cost estimates for remediation and dismantling
  • Bidding documents
  • Project management, construction management, construction supervision
  • Safety and Health Coordination
  • Disposal management

The General Association of Hazardous Material Remediation (Gesamtverband Schadstoffsanierung, GVSS) has certified us as “Remediation experts for surveying and planning” for the remediation of buildings and plants impacted with contaminants.

Moreover the LGA-IUA is qualified as “Examination Center for Contaminated Building Materials and Construction Waste” to perform external quality controls and take on tasks as head technical expert.

The German Demolition Association (Deutscher Abbruchverband, DA) has officially recognized Dr. Kisskalt as an “expert advisor” for the categories “general demolition”, “hazardous building materials” and “waste management”.
