Our draughts men and designers are familiar with the industry standard and ensure meticulous and professional planning, enabling us to implement your projects more efficiently and cost-effectively.

  • Schematic flow diagrams, process flow diagrams and detailed P&I diagrams which comply with DIN and ISO standards
  • Circuit diagrams
  • 2D and 3D models of your production site with
    • All building measurements and outlines, doors, windows etc., in direct cooperation with the architect involved, if relevant
    • The line/pipeline routing for the external supply of all operating consumables to the production site, including pipe bridge layout diagrams and piping isometric drawings
    • The line/pipeline routing within the production site, including piping isometric drawings
    • The main production plant components, such as tanks, drums, pumps, apparatus, valves etc.
    • The electrical installations, control boxes and the routes of the cableways within the production site
    • All steelwork constructions and components, such as stairs, gangways etc., including design and production drawings

In addition to services specific to plant construction, our drawing office also carries out the standards-compliant (DIN ISO) revision and maintenance of your existing drawings on request (schematic flow diagrams, process flow diagrams and P&I diagrams, site plans, general plans, fire defence diagrams, escape route diagrams, explosion protection zone diagrams etc.).
As a supplementary service, we can also survey your site or parts of it and produce a 3D representation of your site using 3D scanning technology on request. This will give you an overall picture of your installations and it will act as the basis for the planning and visualisation of future extensions or conversions.
