A calculation can be perfectly correct and still fail on site if the drawings do not let the crew build what was calculated. The test of a solar drawing package is simple: could a fabricator and an installation team who have never met the designer assemble it correctly?
That depends on three things: complete geometry, clear connection intent and a revision trail everyone trusts.
What the package has to show
General arrangement drawings, member schedules, sections and connection details have to tell the same story. Dimensions, levels, member marks and set-out references belong on the sheet, not left for the site team to infer. Where support or foundation conditions change from one area to another, the drawing should say so and say where.
Status matters too. A tender set, a review set and an approved-for-construction set are different things, and the title block should state which one the sheet is.
- Drawing number, revision and issue status are visible on every sheet.
- Member marks match across plans, schedules and details.
- Dimensions, levels and set-out references are complete.
When site and drawing disagree
The right response is to record the location, note the drawing revision and raise a technical query. Guessing a dimension or changing a connection informally moves the structure away from what was calculated, and nobody downstream knows it happened.
Revisions only work when they reach everyone. Procurement, fabrication, installation and inspection each hold their own copies, so the distribution list and the removal of superseded sheets belong in the issue procedure.
- Keep one controlled register for drawings and comments.
- Mark or remove superseded issues in active work areas.
- Log approvals and agreed deviations.
- Keep as-built information for handover.
