A defined measure of engineering maturity indicating the completeness and reliability of engineering information at a particular stage of a project.
Level of Engineering (LOE) is a structured measure of engineering maturity used to communicate the completeness, accuracy and fitness for use of engineering deliverables during a project. It helps stakeholders understand the confidence that can be placed in designs, estimates and technical decisions at each project phase, from concept through as-built documentation.
Level of Engineering provides a common framework for communicating engineering maturity and supporting project decision-making throughout the project lifecycle.
Organizations typically define multiple LOE stages aligned with project phases such as concept, FEED, detailed engineering, construction and as-built documentation, although the specific definitions vary between organizations.
Level of Engineering measures the maturity of engineering deliverables, whereas Level of Detail and Level of Development describe the maturity of digital models, particularly within BIM workflows.
