The "new" era of BS 8004 began with the 2015 revision, which marked a paradigm shift. Unlike its predecessor, BS 8004:2015 was revised to align fully with the principles of Eurocode 7 (BS EN 1997: Geotechnical Design). This transition was not merely cosmetic; it represented a fundamental change in how engineers think about risk. The standard moved away from "Global Safety Factors" to "Limit State Design" utilizing partial factors. This change allowed for a more nuanced approach to safety, applying specific safety margins to loads (actions) and soil properties (materials) based on the reliability of the data, rather than a single, catch-all safety factor.
