Good practice produces a complete, accurate engineering record: calculations, assumptions, design decisions, correspondence, field notes, change orders, and the basis for professional judgments. Records demonstrate due diligence, allow others to check the work, and protect the practitioner if a decision is later questioned.
Records must be retained for a period set by the regulator, contract, statute of limitations, or the design life of the works, often several years to a decade or more. The guiding idea: keep records long enough that you can defend your decisions and that others can rely on them throughout the asset's life.
- Document the basis of design and any assumptions, so judgments can be reconstructed later.
- Record-keeping supports liability defence: contemporaneous notes are far stronger evidence than later recollection.
- Confidential client records must still be securely stored and properly disposed of when retention ends.
Exam tip: "Why keep records?": to support checking, due diligence, and liability defence, and to allow reliance over the works' life.
