The building official plays a key role in enforcing special <br />inspection requirements specified in the standards. The building <br />official must specify that the trusses were inspected as spe- <br />cified in the code. <br /> <br />Answer to Questign 7~ uBc Standard 2518, Section 25.1825, <br />requires trusses fabricated of plywood components to be 'iden- <br />tified with an appropriate trademark of the approved independent <br />inspection and testing agency. Light metal plates are required <br />to be identified with the plate ~anufacturer's name (See UEC <br />Standard 2518, Section 25.1734(b)4). Trusses fabricated with <br />light metal plates are not required to be marked by the inplant <br />inspection agency; however, a definition of "approved agency" is <br />an established and recognized agency regularly engaged in con- <br />ducting tests or furnishing inspection services once such agency <br />has been approved by the building official. ~nternational <br />Conference of Building Officials has a long lis~ of quality <br />control agencies. In general, each is required to have a logo or <br />stamp. Again, the building official is the key to the control <br />system by demanding evidence that the manufacturer has employed <br />an approved agency. <br /> <br />Answer to Question 8: The building official may authorize job <br />fabrication o~'~the trusses. Quality control must be provided by: <br /> 1. direct inspection by the building official, <br /> 2. fabricator must retain an approved quality control <br /> agency as specified in UBC Standard 25-17, Section 25.1739, <br /> <br /> 3. requiring special inspection as detailed in Section <br /> 306(a)12, "Special Cases", and Section 306(f). <br /> <br />Answer to. Question 9~ As specified in Section 302(b), Exception <br />2,::the buildin~ 'official may waive the requirement for an archi- <br />tect or engineer's design on slngle family residential buildings <br />when he determines that the work is not of a highly technical <br />nature or there is no unreasonable Potential hazard to life <br />and/or safety. The.building official, therefore, may authorize <br />a homeowner to use a handbook design or prepare his own plan. The <br />building official is reminded of the complexity of truss design. <br />If the design has been approved, the buildlng official has the <br />authority to authorize such fabrication. We suggest careful <br />inspection of first trusses so assembled. <br /> <br />Answer to Question 10: ORS 456.750(6) says "A prefabricated <br />structure is a build~ng or structu~ unit which has been in <br />whole or substantial part manufactured in an off site location to <br />be wholly or partially assembled on a site." <br /> <br />A truss is a building component and may be part of a component <br />system. A building component, such as a truss, by itself is not <br />normally regulated as a prefabricated structure since they are <br /> <br /> <br />
