OAR 918-674-0510. Definitions

The following definitions are in addition to those included in ORS 455.010 and ORS 455.705. Definitions in other rules adopted by the division or in Oregon adopted specialty codes apply where applicable to prefabricated structure construction provisions. Where a conflict exists, the specific provision applies over a general provision. (1) “Alteration” means any construction, retrofit or renovation to an Oregon-approved prefabricated building that would typically require a permit for the equivalent construction activity on a site-built building. This includes, but is not limited to, a change in occupancy classification, change of use, reconfiguration of building sections, or changes to a system (structural, plumbing, electrical, mechanical). (2) “Approved” means approved by the Building Codes Division or prefabricated third-party agency. (3) “Audit” means an evaluation of a manufacturer’s compliance control procedure or an examination of prefabricated structure construction by the division. (4) “Building Site” means any lot, tract of land, or an existing building upon which a prefabricated structure is installed. (5) “Closed Construction” means a factory-assembled structure or component that encloses factory-installed structural, mechanical, electrical, plumbing or energy conservation equipment or material inside a floor, wall, or roof cavity that is not entirely open for visual inspection of the equipment or material at the building site. (6) “Compliance Control” means the method of controlling the construction, fabrication, assembly and erection where applicable, including storage and use of various materials, to ensure compliance with the rules and construction codes adopted for the regulation of prefabricated structures. (7) “Component.” (See Prefabricated Structure.) (8) “Design Option” means an alternative design or type of construction associated with a plan. (9) “Division” means the Building Codes Division. (10) “Incomplete Structure” means a prefabricated building that, if approved by the division, is not complete when it leaves the manufacturing facility where approved construction elements will be completed at the building site. Incomplete construction includes, but is not limited to, design, size or transportation limitations, installation of roof framing, installation of plumbing fixtures inside the building, or roof-mounted heating, ventilation or air conditioning equipment. (11) “Insignia of Compliance” has the meaning given in ORS 455.705. (12) “Installation” means the placement, setup, or assembly of a prefabricated structure at a building site, and the process of attaching the prefabricated structure to land, foundation, to an existing building, or within an existing building. (13) “Manufacture” means the process of making, fabricating, constructing, forming or assembling a product from raw, unfinished or semi-finished materials to produce prefabricated structures. (14) “Manufacturer.” (See Registered Manufacturer.) (15) “Manufacturer’s Compliance Control” means an inspection program implemented and maintained by the manufacturer under division certification and audit procedures. (16) “Monitoring” means an evaluation or examination by the division of a prefabricated third-party agency to determine compliance with Oregon laws, rules and the Oregon Specialty Codes. (17) “Notice of plan review” means an official document created by the division or a prefabricated third-party agency during plan review that is attached to an approved set of plans for a prefabricated building. This document is part of the approved plans and must remain attached to the approved plans. (18) “Oregon-approved prefabricated building” is a prefabricated building that when first manufactured complied with the following: (a) Applicable Oregon laws and adopted specialty codes; (b) Constructed and inspected according to division-approved plans for the occupancy classification and intended use; (c) Has Oregon insignia of compliance affixed to the building; and (d) Has not since been altered without approval from the division. (19) “Panel.” (See Prefabricated Component.) (20) “Plan” means a specific design of prefabricated building as designated by the manufacturer to be the working drawings for production of a unit. For the purposes of design options, this is the base plan. (21) “Prefabricated Third-Party Agency” means an independent contractor (private or municipal) certified by the division to provide plan review and inspection services to manufacturers of prefabricated buildings as established in ORS 455.705 and the rules adopted thereunder, and who operates under the authority and direction of the division’s building official charged with the administration of the division’s prefabricated structures program. (22) “Prefabricated Structure” has the meaning given in ORS 455.010 and includes the following types of structures and components: (a) “Prefabricated Component” means any structural subassembly or component such as wall, floor or roof panels; sandwich panels; and reinforced concrete components or subassemblies, provided that they are built at an off-site location using closed construction, but do not contain concealed systems that require inspection prior to concealment. It does not include roof trusses, open wall panels and similar subassemblies that are built at an off-site location using open construction. (b) “Prefabricated Component Building” means a building consisting of prefabricated components and shipped to a building site for assembly. (c) “Prefabricated Building” means either one of the following: (A) “Prefabricated Permanent Building” means a prefabricated structure built as one unit that may be divided into transportable sections and is designed to be permanently installed on a building site. (B) “Prefabricated Relocatable Building” means a prefabricated structure built as one unit that may be divided into transportable sections and is designed to be moved from one location to another. (23) “Reciprocity” means a contractual agreement between two or more states for prefabricated buildings produced in the one state that are designated for sale, rent, lease or installation in the other state. (24) “Registered Manufacturer or Business” means a person, partnership or corporation that has been approved by the division to manufacture or alter prefabricated structures. (25) “Sandwich panel” means a panel made of a minimum of three layers consisting of a core material that is bonded to a skin layer on each side. (26) “Specific Use Structure” means a prefabricated building intended to be used for longer than 30 days in one location and specifically includes the following: (a) “Dedicated Use Structure” means a prefabricated building designed for a specific dedicated use beyond normal shelter or storage, such as hazardous materials buildings, walk-in freezer/coolers, clean rooms or toilet facilities; (b) “Employee Protection-Only Structure” means a prefabricated building that is limited to employee occupancy only such as guard shacks, toll booths and kiosks; and (c) “Equipment Protection-Only Structures” means a prefabricated building used for the protection of stationary equipment that is only occupied during maintenance or servicing of equipment, such as structures housing electronic switching stations, control equipment, power generators, or communications equipment. (27) “Substantial Compliance” has the meaning given in ORS 455.410. (28) “Substantially Prefabricated or Assembled” means a section or the major portion of a prefabricated structure that is assembled in such a manner that all portions may not be fully inspected without disassembly or destruction of the part. (29) “System” means a specific part of the construction, structural, plumbing, electrical or mechanical. [Publications: Publications referenced are available from the agency.]
