In the Swiss civil demolition and building deconstruction sector, the rigorous separation of recyclable mineral aggregates, hazardous building contaminants, and scrap metals underpins operational profitability and legal liability protection. Tightening regulations under the Federal Waste Avoidance and Disposal Ordinance (VVEA), mandatory pre-construction pollutant audits, and paperless waste tracking via the FOEN VeVA platform require demolition contractors to execute exact material stream accounting. Dedicated deconstruction software synchronizes weighbridge slips, containment zone logs, and tipping fees in real time.

1. Statutory Environmental Framework: VVEA Diagnostic Mandates (Art. 16) and Waste Disposal Concepts

Building demolition and deconstruction are governed by the Federal Environmental Protection Act (EPA, SR 814.01) and the Waste Avoidance and Disposal Ordinance (VVEA, SR 814.600):

  • Mandatory Hazardous Building Fabric Audit (Art. 16 VVEA): Prior to securing a demolition or major alteration permit for structures built before 1990, property owners must commission a qualified building diagnostic survey conducted by a certified building pollutant specialist (FAGES / ASCA).
  • Disposal Concept (Art. 16 Para. 2 VVEA): Where expected construction waste volumes exceed 200 m3 or where hazardous substances are present, a written waste disposal concept declaring waste categories, tonnages, and licensed treatment facilities must be submitted to the authorities.
  • Selective Deconstruction (Art. 17 VVEA): Hazardous substances and regulated wastes must be remediated and removed prior to commencing structural demolition (pre-demolition decontamination).

2. Hazardous Materials Management: Asbestos Abatement (Suva 6503), PCBs, PAHs, and Heavy Metals

Remediating building pollutants is subject to strict worker health and safety regulations enforced by Suva:

  1. Asbestos (Suva Directive 6503):
Friable Asbestos (Sprayed insulation, acoustic ceiling tiles, pipe insulation):* Remediation restricted exclusively to Suva-accredited abatement specialists inside hermetically sealed negative-pressure zones (Pdiff ≥ 20 Pa) with 4-stage HEPA H14 filtration and final VDI 3492 clearance air monitoring (< 1'000 fibers/m3). Non-Friable Asbestos (Asbestos cement sheets, vinyl floor tiles):* Low-dust wet dismantling with certified PPE and P3/FFP3 respiratory protection.
  1. PCBs (Polychlorinated Biphenyls per ChemRRV): Removal and high-temperature incineration of elastic joint sealants exhibiting PCB concentrations ≥ 50 mg/kg.
  2. PAHs (Polycyclic Aromatic Hydrocarbons): Abatement of legacy coal-tar parquet adhesives and bitumen roof felt materials.
Mandatory Suva 14-Day Advance Notification

All asbestos abatement operations must be formally notified to Suva and the cantonal labor inspectorate at least 14 days prior to commencing works (Art. 82 UVG). Non-compliance results in immediate site shutdown orders and penal prosecution.

3. Hazardous Waste Tracking: Electronic VeVA Manifests, e-vermark Portal, and Landfill Types A–E

Transport and processing of hazardous wastes are regulated under the Ordinance on the Movement of Waste (VeVA, SR 814.610):

  • Electronic VeVA Waste Manifest: Hazardous wastes (asbestos waste code VeVA 17 06 01 S, PCB-containing waste 17 09 02 S) must be transported under a statutory electronic tracking manifest utilizing a 6-digit FOEN enterprise ID.
  • VVEA Landfill Classifications:
Type A (Inert Soil Landfills):* Exclusively clean excavation subsoil and natural gravel. Type B (Mineral Construction Rubble):* Clean crushed concrete, bricks, and masonry containing low organic content (TOC ≤ 5 %). Type C / D / E (Hazardous and Residual Landfills):* Chemically stabilized residues, incinerator slag, and hazardous industrial wastes.

4. Bills of Quantities & Measurement Takeoffs per NPK 114, BKP 112, and SIA 118

Cost structuring and quantity takeoffs adhere to Swiss construction classification frameworks:

  1. Building Cost Plan BKP 112 (Deconstruction and Demolition): Structural breakdown into building demolition (BKP 112.1), hazardous material remediation (BKP 112.2), contaminated soil excavation (BKP 112.3), and tipping landfill charges (BKP 112.8).
  2. Standard Position Catalog NPK 114 (Demolition and Dismantling Works): CRB standardized items for decontamination airlocks, negative pressure equipment, volumetric (m3) or tonnage (t) demolition, and on-site concrete crushing.
  3. SIA 118 Measurement Rules: Invoicing based on certified weighbridge mass slips or theoretical solid bank volume of the demolished building fabric.
