The same signed cards as the trainer above, in one list to read or print.
- Sizing a footing: what is the order of lookups?
- Soil value first, then the building (stories and construction type), then the R403.1 footing table, then depth and frost protection.IRC 2024 R401.4, R403.1, R403.1.4
- No soil test on site. What soil value can the inspector use?
- The presumptive load-bearing value for the soil class in Table R401.4.1. The AHJ can require a test where soil is doubtful, such as fill, expansive clay or organic soil.IRC 2024 R401.4, Table R401.4.1
- Where does the local frost depth come from?
- Table R301.2, where the jurisdiction fills it in. It is not one national number.IRC 2024 Table R301.2; R403.1.4.1
- Name two ways to give a footing frost protection other than going below the frost line.
- A frost-protected shallow foundation (R403.3), or bearing on solid rock. R403.1.4.1 lists the options.IRC 2024 R403.1.4.1, R403.3
- Why do the footing tables give a brick veneer or solid masonry house a bigger footing than light frame?
- Heavier walls put more load on the soil, so the minimum width and thickness go up.IRC 2024 R403.1
- A footing on a sloping lot: when must it be stepped, and what do you check?
- When its bottom would slope more than R403.1.5 allows. Each step then bears on level ground. Check the trench bottom, not the top of the form.IRC 2024 R403.1.5
- A footing sits near the edge of a slope. Which section?
- R403.1.7, because the soil in front of the footing could give way.IRC 2024 R403.1.7
- Expansive soils, wood foundations, precast concrete foundations: where?
- Expansive soils R403.1.8. Wood foundations R401.1, R403.2 and R404.2. Precast concrete R403.4 and R404.5.IRC 2024 R403.1.8, R403.2, R403.4, R404.2, R404.5
- A column bears on a footing. What is the inspector's main check?
- Restraint at the base so the column cannot slide off, plus the beam connection at the top. A wood column on concrete also brings in decay protection (R304).IRC 2024 R407; R304
- A concrete foundation wall table needs which three facts from the field?
- Wall height, height of unbalanced backfill, and soil class.IRC 2024 R404.1
- Sill plate anchor bolts: what are the checks?
- Bolt size, embedment and spacing; a bolt near each end of every plate piece; washers and nuts on before framing covers them. Straps, where used, go in to their instructions.IRC 2024 R403.1.6
- Before checking foundation anchorage, what should you look up in Table R301.2?
- The seismic design category. Higher categories add anchorage rules.IRC 2024 Table R301.2; R403.1.6
