Conceptual Design, FEED, Detailed Design and Engineering Consultancy Services


Conceptual Design is an early phase of the design process, in which the broad outlines of function and form of something are articulated. It includes the design of interactions, experiences, processes and strategies. It involves an understanding of peoples needs - and how to meet them with products, services, & processes. Common artifacts of conceptual design are concept sketches and models.

FEED (Front End Engineering Design) means Basic Engineering which is conducted after completion of Conceptual Design or Feasibility Study. At this stage, before the start of EPC (Engineering, Procurement and Construction), various studies take place to figure out technical issues and estimate rough investment costs. This work is normally contracted to EPC contractors such as Chiyoda, as an optional contract or through bidding. The product of the activity is called “FEED Package” which amounts up to dozens of files and will be the basis of bidding for EPC Contract.

It is important to reflect the clients intentions and project-specific requirements into the FEED Package without fail, in order to avoid significant change during EPC Phase. The FEED Work takes about 1 year in case of a large-sized project such as an LNG plant. As it is essential to maintain close communication with the client, it is a common practice that client stations at the Contractor’s office during the work execution.

Detailed Design and engineering follows a process that entails conceptual design, embodiment design and detail design and, when performed professionally, eventually results in a well-designed solution.
Conceptual design is Phase One of detailed design and engineering in which drawings are the main output. The drawings produced are often quite simple ideas with little detail, but the aim of the conceptual phase is to commit ideas to paper.
Detailed design is the phase where the design is refined and plans, specifications and estimates are created. Detailed design will include outputs such as 2D and 3D models, P & ID’s, cost build-up estimates, procurement plans etc. This phase is where the full cost of the project is identified.
