The Challenge

The biggest contribution to the project’s duration is made by the detail engineering phase. As in all cases, the scope and complexity of detail engineering activities essentially depends on the type and size of the project. The most important working points during the detail engineering are:


  • Process engineering design of the apparatus including strength calculations
  • Preparation of technical specifications
  • Pipeline planning & statics
  • P&ID flow charts
  • Installation planning
  • Documentation




Detailed planning is a highly multidisciplinary process that involves many specialists whose goal is to complete in detail, fix and establish package plans for all the requested units. The variety of activities in the planning area should not be underestimated.

Many documents in the detailed planning phase cannot be processed independently of each other. Piping isometrics, for example, can only be finalized once the piping plans are available. Piping plans can only be finalized when the final layout, the piping and instrument flow diagrams as well as the corresponding pipe route plans are submitted. The specific nominal diameters in the piping and instrument flow diagrams require the hydraulic design to be carried out. Finally, when new documents are created, additional changes may occur for documents that already exist, which in turn are essential for the creation of new documents.

For all above reasons, EPD Engineering Services trust AutoCad Plant 3D to design the facilities.



The planning results of this engineering phase are handed over to the procurement process in the form of tender and inquiry documents with defined specifications for all technical equipment and materials required for the construction of the process plant, including assembly services. The services of basic and/or detail engineering can also be requested separately from EPD Engineering Services. We always collaborate with the Client in a customized way that suits to  its individual needs.


EPD Engineering Services presents comprehensive Plant Design Engineering Services that include design, analysis, and procurement solutions.

We perform plant design and construction for our clients with state-of-the-art 3D planning and engineering tools. We utilise the latest 3D modelling software for each phase of project design development, from conceptual to definitive design, right through to the production of documentation for construction.

Our services range from machine engineering and finite element analysis to fully integrated, multi-disciplinary industrial plant design.

It includes the preparation of layouts and General Arrangement (GA) drawings, equipment design and specifications/data sheets, fabrication and shop drawings, piping design, arrangement, spool generation, isometric drawings and bill of materials, Finite Element Analysis (FEA), vendor document approval, drafting and 3D modeling, and as-built documentation.
