When in the course of inspections of the initial industrialized unit, the third-party inspection entity identifies items of non-conformance with the approved construction documents, the items are to be corrected and the next unit(s) are to be inspected in accordance with this section until no further items of non-conformance have been identified in subsequent units. Records of initial inspections, including items of non-conformance and corrective action, are to be maintained by the third-party inspection entity and provided to the board upon request.

(2) Subsequent reduced inspections. Where the initial inspections of industrialized units have demonstrated that the manufacturer's compliance assurance program is capable of assuring that the industrialized units produced are built in accordance with the construction documents approved by the board and no further items of non-conformance have been identified by the inspector in accordance with paragraph (C)(1) of this rule, then the manufacturer may choose to self-perform required inspections of each module or panel of subsequent industrialized units. Such inspections are to be performed by an employee of the manufacturer who is certified by the board of building standards in accordance with rule 4101:10-9-01 of the Administrative Code to inspect the scope of construction under the authorization. Records of such inspections, including items of non-conformance and corrective action, are to be maintained by the manufacturer and provided to the board upon request. For manufacturers that produce five or more units of any authorized industrialized units, the third-party inspection entity is to visit the manufacturing plant, at random times at least four times per year, and conduct inspections of units intended for Ohio, audit the manufacturer's plant evaluation and compliance assurance program and review the record of inspections.

Exception: Where the manufacturer does not self-perform required inspections, the third-party inspection entity is to perform at least one on-site inspection of "open" construction of each subsequent industrialized unit. The inspection is to include but is not limited to the rough framing and the rough building services inspections. Inspection of individual modules or panels of the same industrialized unit inspected at different phases of completion is acceptable provided at least one module or panel allows for rough framing inspection and one allows for rough building services inspection. Records of inspections completed under this exception, including items of non-conformance and corrective action, are to be maintained by the third-party inspection entity and provided to the board upon request.

(3) Increased inspections. Notwithstanding the above, upon notification by a third-party inspection entity to the board and the manufacturer that the compliance assurance program of a manufacturer does not sufficiently ensure compliance with the approved construction documents, or on the board's own motion, increased inspection frequency may be ordered by the board so that each assembly or component will be inspected by the third-party inspection entity. These inspections are to continue until an inspection demonstrates that the manufacturer's control of the materials and processes used is sufficient to ensure that the units are constructed in accordance with the approved construction documents. Records of such inspections, including items of non-conformance and corrective action, are to be maintained by the third-party inspection entity and provided to the board upon request.

(4) Remote inspections. All inspections are to be in-plant except that a third-party inspection entity may provide remote virtual inspection when the third-party inspection entity has an established program for conducting remote inspections where directed by the inspector, recorded and conducted in real time.

(D) Insignia required. Each modular unit or panelized unit or equipment unit of an authorized industrialized unit must have an insignia applied.

(1) Insignia acquisition. An insignia is to be obtained from the board for each industrialized unit module or panel to be used within the state of Ohio.

(2) Insignia placement. The insignia is to be affixed to each unit, in the location identified in the authorized construction documents, after a determination is made by the third-party inspection entity that the unit is constructed in accordance with the construction documents authorized by the board.

(a) For industrialized units inspected per paragraph (C)(1) of this rule, the insignia cannot be applied until after the final inspection is completed by the third party and is satisfactory.

(b) For industrialized units inspected per paragraph (C)(2) of this rule, the manufacturer is extended the authority to apply the insignia to the self-inspected units provided the third party audit of inspections and process is kept in good standing and increased inspections are not required.

(c) For industrialized units inspected per paragraph (C)(3) of this rule, the board has the authority and discretion to direct who is to apply insignias, under what conditions, for how long and the conditions under which the manufacturer can earn the right to apply insignias.

(3) Insignia signifies. An insignia, applied to the unit, constitutes final approval of the unit as compliant with the requirements of the applicable building code.

(4) Insignia expiration. An insignia expires at either of the following events:

(a) After the building owner receives a certificate of occupancy for the building in which the industrialized unit with this specific insignia is installed.

(b) After two years from the effective date of the subsequent model-based building code.

(5) Assemblies without insignia. Modules, panels or equipment units constructed without an authorization or arriving at the site of intended use without an insignia from the board of building standards are not industrialized units.

(E) Adjudication orders required. When the board of building standards denies any authorization or takes action in response to findings of non-compliance with the rules of the board, such action is to be initiated by issuing an adjudication order, prior to seeking any remedy, civil or criminal.

(1) Response to orders. The person receiving an order shall exercise their right to appeal within thirty days of the issuance of the order, comply with the order, or otherwise be released from the order by the board of building standards.

(2) Time limitation of application.
