Start with the outcome
Tell us what is being built or changed, where the project is located, who will use the drawings and the date you are working toward. Include any submission checklist or reviewer comments you already have.
Build one source folder
Keep the most recent plans, survey, photos and written scope together. Label superseded drawings clearly. If a PDF and DWG disagree, identify which file should govern before drafting starts.
Make field measurements readable
Label rooms consistently across sketches and photos. Record overall dimensions as well as individual segments. Flag measurements you could not access rather than estimating them without a note.
Mark changes in one place
Use a consolidated markup and one person to collect feedback. Separate corrections to source information from new design decisions. That distinction helps the drafting team scope revisions and keep issue dates clear.
Confirm the handoff format
Agree on sheet size, PDF output, editable file needs and software versions. An organized handoff reduces clarification cycles; it does not replace field verification or required professional review.
