NEW QUESTION # 18
In mass timber construction of Type IV-C, the fire-resistance ratings of bearing walls are permitted to be reduced by _____ where supporting a roof only.
Answer: D
Explanation:
IBC Table 601, Footnote "a," permits a one-hour reduction in the required fire-resistance rating of the primary structural frame and bearing walls where those elements support a roof only. Option C is therefore correct.
For Type IV-C construction, the normal Table 601 requirement for bearing walls is two hours. Where a bearing wall qualifies as supporting only roof construction, application of the footnote permits that rating to be reduced from two hours to one hour.
The limitation "supporting a roof only" is critical. The reduction cannot be applied simply because a wall is located at the uppermost occupied level. If the wall carries a floor, mezzanine, transfer load, occupied rooftop structure, or another structural element beyond qualifying roof construction, the condition for the reduction is not satisfied.
Options A and B are not reductions prescribed by Table 601. Option D would effectively eliminate the entire normal two-hour Type IV-C bearing-wall rating, which the footnote does not permit.
For inspection purposes, the approved construction documents and structural load path must substantiate use of the reduction. The fire-protection installation should then be checked against the actual reduced rating specifically authorized by the design.

NEW QUESTION # 19
Where Type X gypsum board serves as noncombustible protection for interior surfaces of wall and ceiling assemblies, all of the following code provisions are correct except:
Answer: A
Explanation:
Option D is the incorrect statement. IBC Section 722.7.2.1 requires the panel edges of the face layer , rather than the base layer, to be taped and finished with joint compound. Fastener heads on the face layer must also be covered with joint compound.
The other three provisions accurately reproduce the code. Each gypsum-board layer must be secured with Type S drywall screws long enough to penetrate the mass timber at least 1 inch when driven flush. Screws for the base layer are installed at 12 inches on center in both directions . Subsequent layers use the same general spacing but are offset from screws in the preceding layer. In addition, the panel edges of each succeeding layer must be offset 18 inches from the panel edges of the previous layer.
These details are not merely workmanship recommendations. They form part of the installation conditions under which the protection contributions in Table 722.7.1(2) can be credited.

NEW QUESTION # 20
Buildings of Types IV-A, IV-B, and IV-C construction designed to be greater than six stories above grade plane shall meet which of the following requirements for fire safety practices during construction?
Answer: B
Explanation:
The 2021 IFC specifically requires standpipes to be provided in accordance with Section 3313 for Type IV-A, IV-B, and IV-C buildings designed to exceed six stories above grade plane. Therefore, option A is correct.
The code also requires a water supply for fire department operations, but it must be approved by the fire code official and fire chief; it is not described as a mandatory "portable water supply." This makes option B inaccurate. Where noncombustible protection is required, at least one layer-not two layers-must be installed on applicable building elements more than four levels below active mass timber construction before additional levels are erected. Option D therefore overstates the number of layers.
Required exterior wall coverings must similarly be installed more than four levels below active mass timber construction. Option C incorrectly substitutes two levels for the prescribed four-level threshold.
These provisions limit the amount of unprotected combustible construction exposed at one time and provide the fire department with usable suppression infrastructure as erection progresses. Inspection coordination should verify standpipe extension, hose-connection accessibility, water availability, the progression of passive protection, and exterior-wall covering installation.
References/Topics: 2021 IFC Section 3308.4 and Section 3313; fire safety during construction of tall mass timber buildings.
NEW QUESTION # 21
The fire-resistance of a protected mass timber assembly is equivalent to the fire resistance time of the:
Answer: B
Explanation:
IBC Section 722.7 establishes the governing calculation principle for protected mass timber. The required fire resistance consists of the inherent fire resistance of the unprotected mass timber element plus the protection time contributed by the noncombustible protection . Therefore, option D is correct.
This approach recognizes two sequential protective mechanisms. First, the noncombustible covering delays heating and charring of the timber. After the credited protection period, the remaining mass timber cross section provides structural fire resistance through predictable charring behavior and residual section capacity.
Section 722.7.1 further requires the contribution of the covering material to comply with the prescribed protection times or to be established under Section 703.6.
Option A ignores the contribution of the protective membrane. Option B ignores the inherent structural fire resistance of the timber. Option C incorrectly substitutes a finish rating for the code-recognized protection contribution. A finish rating is a separate temperature-based performance concept and is not automatically additive as the protection time used by Section 722.7.

NEW QUESTION # 22
Combustible construction forming concealed spaces shall be protected with noncombustible protection with an assigned time of 40 minutes in which construction type?
Answer: D
Explanation:
The requirement applies to Type IV-C construction. Under the 2021 IBC provisions governing Type IV-C, combustible construction forming concealed spaces must be protected with noncombustible protection having an assigned protection time of not less than 40 minutes. Therefore, option C is correct.
The assigned protection time is determined using the protection-time values prescribed by the code, including the applicable values for gypsum board and other approved noncombustible materials. The provision is intended to delay ignition and involvement of combustible mass timber surfaces located within concealed spaces, where fire growth might otherwise remain undetected and become difficult for fire-suppression personnel to access.
Type IV-A and Type IV-B are subject to more extensive noncombustible protection requirements because those construction types support taller buildings and require greater protection of mass timber elements. Type IV-HT uses the traditional heavy-timber concealed-space provisions and may employ alternative methods, such as complete filling with noncombustible insulation.
During inspection, the special inspector must confirm that the installed layers, thicknesses, fastening patterns, joints, penetrations, and transitions collectively provide the required 40-minute assigned protection time.
