Plant and project documentation of power and processing plants. As-built documentation


Plant documentation is commonly referred to as “as-built” documentation. In the course of assembly or installation, the following documents must be provided to the operators:


  • Plant description
  • Functional description of the entire plant and its constituent parts
  • Operating and maintenance instructions
  • Technical drawings and plans
  • CE marking, manufacturer’s recommendation, certificate of conformity
  • Inspection results and inspection reports


There are different reasons for why customers are missing documents or these documents are no longer valid:


  • Changed government regulations
  • Changed government requirements and/or standard requirements
  • Old plants with undocumented modifications
  • No prior as-built documentation
  • Loss due to force majeure
