Does engineering certification cover the whole build or just the slab?

This genuinely depends on your project — a single engineer might certify just your slab, while a broader structural design (framing, upper floors) could involve the same or a different engineer, depending on how your project is structured.

For a standard new home, your builder typically coordinates the full structural engineering scope needed across the whole build, though the slab specifically has its own distinct certification requirement within that broader process.

Understanding exactly what scope your specific engineering engagement covers — worth clarifying directly — avoids any gap in certification coverage across your overall project.
