What is the difference between Front End Engineering Design and Detailed Design Engineering?

Front End Engineering Design (FEED) focuses on the initial phase of a project, where concepts are developed, feasibility is assessed, and high-level designs are created to outline the project's scope, costs, and timelines. In contrast, Detailed Design Engineering involves the comprehensive development of the project’s specifications, drawings, and engineering documents needed for construction, ensuring that all design elements are accurately defined and ready for implementation. Essentially, FEED sets the foundation, while Detailed Design Engineering provides the intricate details necessary for execution.
