                        International Code Council 93-Tall-Mass-Timber-Buildings Sample Questions (Q59-Q64):

                        NEW QUESTION # 59
                        Which of the following requires periodic special inspection of mass timber elements?

                        Answer: A

                        Explanation:
                        Concealed connections in Type IV-C construction require periodic special inspection under 2021 IBC Table
                        1705.5.3, making option B correct.
                        The mass timber special-inspection table specifically applies to mass timber elements in Types IV-A, IV-B, and IV-C . Among the activities listed for periodic inspection are bolted connections, concealed connections, erection of mass timber construction, screw installation, verification of required predrilling, and several other connection-related installation characteristics.
                        Options A and C are incorrect because they specify Type IV-HT. Table 1705.5.3 is expressly scoped to Types IV-A, IV-B, and IV-C rather than Type IV-HT. Option D involves a listed Type IV-A activity, but its inspection frequency is wrong: adhesive anchors installed horizontally or upwardly inclined to resist sustained tension loads require continuous , not periodic, special inspection.
                        For concealed connections, inspection must occur while the relevant components remain observable. Once CLT panels, wood cover, gypsum protection, or finishes hide the connection, critical installation details may no longer be verifiable without destructive removal.
                        References/Topics: 2021 IBC Section 1705.5.3 and Table 1705.5.3, Required Special Inspections of Mass Timber Construction.


                        NEW QUESTION # 60
                        Which of the following requires continuous special inspection?

                        Answer: D

                        Explanation:
                        Adhesive anchors installed horizontally to resist sustained tension loads require continuous special inspection.
                        Therefore, option D is correct.
                        Continuous special inspection means that the special inspector must be present during the performance of the regulated work. This heightened oversight is necessary because horizontal or upwardly inclined adhesive- anchor installations resisting sustained tension are sensitive to installation variables such as borehole cleaning, adhesive proportioning, mixing, placement, embedment depth, temperature, cure time, and prevention of adhesive loss before curing. A concealed installation defect can substantially reduce long-term tension capacity.
                        The other listed activities are generally subject to periodic inspection under the mass timber special-inspection provisions. Periodic inspection allows the inspector to observe the work intermittently at appropriate stages rather than remaining present throughout the entire operation. Bolted connections, concealed mass timber connections, and anchorage of mass timber construction to deep foundation systems must still be inspected, but the code does not automatically designate each of those activities as continuous.
                        The inspector should also verify installer certification where required, approved adhesive-anchor evaluation documentation, expiration dates, storage conditions, drilling method, hole dimensions, and compliance with the approved structural documents.
                        References/Topics: 2021 IBC Sections 1705.3 and 1705.5.3; Table 1705.3; continuous inspection of adhesive anchors under sustained tension.


                        NEW QUESTION # 61
                        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.
                        References/Topics: 2021 IBC Section 722.7.2.1, Items 1-9; fastening, panel-edge offset, and finishing of Type X gypsum protection.


                        NEW QUESTION # 62
                        When Type X gypsum board is used as noncombustible protection over mass timber on the building ' s exterior walls, which of the following fasteners are permitted?

                        Answer: C

                        Explanation:
                        Option A reproduces one of the two permitted exterior gypsum-board fastening methods in 2021 IBC Section
                        722.7.2.2. Type X gypsum board used as noncombustible protection on the exterior side of mass timber walls may be attached using galvanized nails of minimum 12 gage with a 7/16-inch head and sufficient length to penetrate the mass timber at least 1 inch .
                        The code also permits ASTM C1002 Type S, W, or G screws, but those screws must likewise penetrate the mass timber a minimum of 1 inch . Options C and D are therefore incorrect because they specify only 3/4- inch and 7/8-inch penetration, respectively. Option B is incorrect because it substitutes 16-gage nails for the minimum 12-gage requirement.
                        Section 722.7.2.2 additionally requires exterior Type X gypsum-board layers to be fastened 12 inches on center each way and 6 inches on center at joints or ends. Panel-edge fasteners must be located at least 1 inch and not more than 2 inches from the edge.
                        These fastening details are part of the conditions necessary to claim the protection contribution in Table
                        722.7.1(2).
                        References/Topics: 2021 IBC Sections 722.7.1 and 722.7.2.2; exterior Type X gypsum-board protection.


                        NEW QUESTION # 63
                        For Type IV-A, IV-B, and IV-C construction, each of the following materials on the exterior side of mass timber exterior walls is required to be noncombustible except:

                        Answer: C

                        Explanation:
                        The code provides a specific combustible-material exception for qualifying water-resistive barriers , making option D correct. The exterior-protection provisions for Types IV-A, IV-B, and IV-C require the exterior side of mass timber walls to receive noncombustible protection with at least a 40-minute assigned protection time, and components of the exterior wall covering are generally required to be noncombustible.
                        A water-resistive barrier may be combustible only where it satisfies stringent fire-performance criteria.
                        Among those criteria, the 2021 IBC limits peak heat-release rate and total heat release under ASTM E1354 and establishes flame-spread and smoke-developed limits under ASTM E84 or UL 723. The provision therefore does not create a blanket exemption for arbitrary combustible membranes.
                        Insulation, exterior cladding, and architectural components forming part of the regulated exterior wall covering must comply with the applicable noncombustibility requirements unless some other express code allowance applies. The WRB is the specifically identified exception tested by this question.
                        During inspection, product identification and fire-test documentation should be checked rather than assuming that a membrane qualifies merely because it is marketed as a water-resistive barrier.
                        References/Topics: 2021 IBC Sections 602.4.1.1, 602.4.2.1 and 602.4.3.1; exterior wall protection and qualifying water-resistive barriers.
