Demolition and Disposal

From the baseline sampling of suspected hazardous building materials to building restoration and the selective deconstruction of buildings to construction site clearance, the unsealing of operational areas to land recycling of entire brownfields, experts from a wide range of disciplines work together in order to find economical and sustainable solutions for our clients.

From the initial planning stages to the approval inspection of a structure, our competent coordinators monitor all project steps for compliance with occupational health and safety requirements.
Our clients may rely on professional construction coordination, construction supervision, and disposal management.

Protection of Occupational Health and Safety

  • DGUV 101-004 and TRGS 524 (German Statuary Accident Insurance and Technical Rules for Hazardous Substances): Preparation of health and safety plans for work in contaminated areas and appointment of a health and safety (ArSi) coordinator
  • TRGS 519 (asbestos) and TRGS 521 (old mineral wool): Preparation of health and safety plans and appointment of a competent coordinator
  • Construction Site Ordinance: Preparation of health and safety plans, advance notices and documents required for the subsequent operation of equipment within the scope of all types of underground civil engineering and remediation measures, and appointment of a health and safety (SiGeKo) coordinator

Exploration of Hazardous Building Materials

  • Historical research
  • Preparation of customized sampling concepts
  • Specific sampling of building components suspected of contamination (e.g. asbestos, MMF (artificial manmade fibers), PAH (polycyclic aromatic hydrocarbons), PCB (polychlorinated biphenyls), DDT (dichlorodiphenyltrichoroethane), TPH (total petroleum hydrocarbons), etc.)
  • Sampling of mineral building structure, preliminary classification of mineral waste materials
  • Compilation of contaminant registers
  • Compilation of survey reports
  • Assessment of remediation necessity

Planning Services, Building Restoration and Deconstruction

  • Procurement and assessment of existing documents and plans, building inspections and field surveys
  • Compilation of room inspection logs / building inspection logs
  • Preparation of remediation / deconstruction concepts based on results of contaminant surveys
  • Disposal planning and preparation of disposal concepts broken down by waste categories for recovery or disposal
  • Remediation / deconstruction planning, quantity surveys, compilation of service specifications
  • Preparation for and participation in contracting of construction works

Construction Site Coordination and Management

  • Coordination regarding compliance in terms of occupational safety specifications (appointment of an ArSi / SiGe coordinator according to TRGS 519, 521)
  • Expert supervision of demolition work
  • Performance of sampling for proof of compliance and – according to LAGA PN98 (Länder Working Group on Waste) – declaration analysis purposes
  • Invoice verification; cost monitoring
  • Change order management
  • Site management by compilation of aerial imagery and 3D modeling using drones
  • Ecological monitoring of construction projects

Disposal Management

  • Sampling of accumulating construction waste (LAGA PN98)
  • Computer-based declaration / waste disposal management according to LAWA, LAGA, Länder Working Groups on Water and Waste) DepV (Landfill Ordinance), EPP (Position Paper), RC Guideline & BBodSchG (Federal Soil Protection Act)
  • Consultation regarding potential disposal paths / waste treatment
  • Waste management and coordination
  • Performance of electronic disposal certification process for hazardous waste (eANV)
  • Drone-based stockpile survey and documentation of results

Construction Site Clearance and Land Recycling

  • Construction site clearance in terms of legacy pollution, ground risk and warfare agents in the area of current and former military installations and weapon production sites as well as in industrial and commercial areas
  • Promotion of percolation of rainwater from sealed areas: cost/benefit calculations
  • Investment in unsealing and percolation systems
  • Promotion or re-use of resources by way of selective deconstruction
  • Clean-up or containment of legacy pollution through treatment, soil excavation, relocation, sealing/waterproofing or encapsulation
  • Preparation of concepts, planning services, supervision of construction implementation

GIS and Database Development

  • Computer-based declaration / disposal management according to Länder Working Groups on Water and Waste) DepV (Landfill Ordinance), EPP (Position Paper), RC Guideline & BBodSchG (Federal Soil Protection Act)
  • Digital processing of building surveys
  • Stockpile documentation and management based on aerial images generated using drones and 3D modeling
