Definition
Structural drawings define the load-bearing elements: footings, ground beams, columns, beams, slabs and stairs, with sizes, levels, reinforcement details and concrete grade, plus general notes for construction.
Why it matters on a project
They secure the building's safety and are required for the permit. The bar bending schedule and the take-off of concrete and formwork come from them.
Measurement and pricing
Concrete in cubic metres per element, steel in tonnes from the bar bending schedule, formwork in square metres.
Common mistake
Building from a superseded revision, or without checking against the architectural set, so columns land in doorways or beams under windows.
Frequently asked questions
Does a villa need structural drawings?
Yes, they are required for the building permit and designed to the Saudi code and the soil report.
How do they differ from structural shop drawings?
Structural drawings set the design; shop drawings and bending schedules turn it into exact details for every bar.
