⚠ If cracks are widening, floors are sagging fast or concrete is falling, stop using that part of the building now and call a structural engineer. Do not wait for a score.
1. When was the building constructed?
2. Was the structure designed by a structural engineer, and do you have the drawings?
3. Have floors been added since the building was first built?
4. Has the use of the building changed (for example, residential to factory or storage)?
5. Are there heavy loads on upper floors — machinery, stacked goods, generators, boilers or large water tanks?
6. Are there cracks in columns or beams, or diagonal cracks in walls?
7. Do you see rust stains, or concrete falling away to expose steel bars?
8. Do floors sag, slope, or do doors and windows jam?
9. Is the ground floor mostly open (parking or shops) with walls on the floors above?
10. What is the ground like?
11. Is there persistent leakage, dampness or flooding around the structure?
12. When was the structure last assessed by an engineer?
