👉 Preliminary engineering is the foundational phase of a project where the feasibility and basic design of an engineering solution are assessed. It involves identifying the problem, gathering data, and conducting preliminary analyses to determine if a project is viable. This stage includes feasibility studies, risk assessments, and preliminary design concepts to outline the scope and basic parameters of the project. Engineers at this level collaborate with stakeholders to refine ideas, ensuring that the proposed solution meets technical requirements and budget constraints while laying the groundwork for more detailed engineering work.
