Our firm has switched to the term "record drawings" and we now use it exclusively. Several engineering organizations, particularly civil eng and geotechnical, encourage the use of "record drawings" rather than "as builts." The reason behind this is that the term "as-built drawing" has been used against engineers numerous times in court and the term seems to have a legal meaning that the "as built" drawing shows everything absolutely as it exists in the field. In reality, we can't verify every detail unless we see every weld, test every cubic foot of backfill for density, watch the contractor's every move during construction, etc. The term "record drawing" seems to have a legal meaning that to the best of our knowledge, we believe that what we're showing on the drawing is how it exists after construction.
