In the change of project intention into its implementation, there is a journey through engineering. Assessment of input conditions, suggestion of possible concepts, optimisation of design documentation specification of purchased goods and documents for manufacture, documentation for installation and testing– we know this all.

1. Conceptual design

It usually contains dimensional requirements of the main equipment, its positioning plan, description of operational and process conditions, interconnection between surrounding equipment and devices.

Usual scope of documentation contains:

  • Process data and overviews
  • Calculation of preliminary design of thermal / mass balance scheme (K-Pro,
  • Questionnaires
  • General layout of the main buildings positioning
  • Positioning of equipment within systems and buildings

2. Basic design

In details processed set of documents consisting of drawings, technical reports, list of materials and equipment, specifications of all important parts, description of the main control loops and function groups during all operational stages (start up, normal and emergency operation, shut down).

Usual scope of documentation contains:

  • Land layout
  • Basic processes and measurements (P&ID schemes) and process diagrams (PFD/UFD diagrams)
  • Technical report and process description of all units
  • 2D and 3D drawings of construction units and isometric designs
  • Philosophy of operation and management, emergency switch-off, operation during start up and shut down of equipment

3. Detailed design

Final stage of design documentation with all necessary and compulsory information for the equipment supplier or manufacturer.

Usual scope of documentation contains:

  • Technical reports
  • Detailed drawings
  • Installation drawings
  • List of items
  • Welding plan
  • Static calculation (pressure parts, steel and concrete structures)
  • Purchase specification

Real scope of engineering design depends on client’s requirements.
