Final answer:
Inspecting architectural drawings, testing structural materials, and analyzing soil composition.
Step-by-step explanation:
The activities that will allow an engineer to determine that a building's design is sound are:
- Inspecting architectural drawings: By examining the architectural drawings, engineers can identify any design flaws or areas that may pose structural risks.
- Testing structural materials: Engineers can conduct tests on materials such as concrete, steel, or wood to ensure they meet the necessary strength and durability requirements.
- Analyzing soil composition: By studying the soil composition at the building site, engineers can determine whether the foundation will be secure and stable.
