Key Concepts

Design method and sizing basics - Wall framing (exterior and interior) shall be in accordance with Section 2308 unless a specific design is furnished (IBC 2021, Section 2304.3). - Where dimensions of lumber are specified in Chapter 23, they are nominal dimensions unless specifically designated as actual (Section 2301.2). Computations to determine required member sizes shall be based on net dimensions (actual sizes), not nominal sizes (Section 2304.2). - Studs shall have full bearing on a 2-inch-thick (actual 1½-inch) or larger plate or sill having a width not less than equal to the width of the studs (Section 2304.3.1).

Key Concepts

Pre-erection and site readiness - The steel erector must receive written notification that the concrete or mortar has attained either 75 percent of the intended minimum compressive design strength (based on an appropriate ASTM field-cured sample test method) or sufficient strength to support the loads imposed during steel erection — 29 CFR 1926.752(a)(1) and (b). - Job planning rests with the owner's designated representative for design (ODRD), who works with the owner's designated representative for construction (ODRC) — the party responsible to the owner for overall construction, planning, quality and completion, usually the general contractor or construction manager on site (Study Guide, Structural Ironworking Two, Sec. 2.3.1). - A competent person must determine the erection sequence before…

Key Concepts

Roof slope limits and underlayment - Asphalt shingles shall only be used on roof slopes of 2 units vertical in 12 units horizontal (2:12) or greater; slopes from 2:12 to less than 4:12 require double underlayment (IBC 2021, Section 1507.2.2). - Asphalt shingles shall be tested in accordance with ASTM D7158 and meet the classification requirements of Table 1504.2 for the appropriate maximum basic wind speed; packaging must bear a label showing compliance.

Key Concepts

• Scope. Chapter 29 and the International Plumbing Code govern design, construction, erection and installation of plumbing components, appliances, equipment and systems. Toilet and bathing rooms are constructed per Section 1210. (IBC 2021, Section 2901.1)
• Minimum fixtures. Fixtures shall be provided in the minimum number shown in Table 2902.1 based on the actual use of the building or space. Uses not shown in the table are considered individually by the code official. (Section 2902.1)
• Fixture calculations. To determine the occupant load of each sex, the total occupant load is divided in half; the fixture ratio(s) for each…

The verified questions for this topic all come from one place: IBC 2021, Chapter 28 (Mechanical Systems), Section 2801.1. That single scope section is the highest-yield text available in the SOURCE.

Key Concepts

Chapter 28 is a linking chapter. The user note on page 652 of the 2021 International Building Code states: "Mechanical systems are a key element of any building. Chapter 28 regulates such systems by linking to the International Mechanical Code® and International Fuel Gas Code®, where details of mechanical system requirements are provided." Chapter 28 itself contains Section 2801, General, and Section 2801.1, Scope — the detailed technical rules live in the referenced codes.

Emergency and Standby Power Systems (IBC Chapter 27)

The SOURCE for this topic is IBC 2021 Chapter 27, Electrical. It covers only Section 2701 (Scope) and Section 2702 (Emergency and Standby Power Systems). Nothing in the SOURCE addresses GFCI/AFCI protection, service sizing, grounding and bonding, branch circuits, receptacle spacing, wiring methods/conduit fill or panelboard clearances, so this brief is limited to the chapter's emergency and standby power provisions. The most efficient preparation is memorizing the numbered durations, capacities and ratings in Section 2702.
