Section R. 408.31133 - Building systemsRule 1133.
(1) To obtain approval for premanufactured units or building components, a manufacturer shall submit a building system for evaluation by the bureau in accordance with the requirements of R 408.31151. Building systems shall be identified by model number or component number.(2) Before a full evaluation, the bureau shall determine that building systems submitted to it are suitable for processing. If the application is found to be unsuitable for processing, the applicant shall be notified in writing of the unsuitability and the basis thereof within 30 days of the date the application is received by the bureau and a portion of the fee may be returned. The finding of unsuitability is without prejudice. A subsequent submission shall be treated as a new application.(3) The bureau may require tests to determine whether a building system meets the codes, standards, and requirements of the act and these rules, if that determination cannot be made from evaluation of plans, specifications, and documentation alone. The procedures used shall be reviewed and evaluated by the bureau.(4) If a building system is disapproved, the bureau shall notify the applicant with a written explanation of the reasons for disapproval attached thereto.(5) Approval of a building system shall be evidenced by the stamp of approval of the bureau on each sheet, or by other effective means of identification. Each sheet shall be numbered serially and shall indicate effective dates of revision. One copy of all plans, specifications, and documentation shall be returned to the applicant.(6) The bureau shall prepare and issue to the applicant a building system approval report signed by the drafter and by the person in charge of the evaluation. The report shall be numbered and shall contain a summary description of the building system and all of the conditions of its use including installation instructions.(7) A building system, or an amendment thereto which has been approved, shall not be altered without prior authorization by the bureau. All approved changes shall be made a part of the written record of the approval. The authorization shall be in writing or be confirmed in writing within 10 days of any oral authorization.(8) A change in the codes, standards, specifications, and requirements shall not apply retroactively. The bureau shall notify all manufacturers with approved building systems and evaluation agencies of all changes. Each manufacturer shall submit to the bureau the necessary amendments to its already approved building systems.
(9) Amendments to building systems may be proposed by submitting to the bureau for approval, appropriate plans, specifications, or documentation showing the effect of the proposed amendment on each building system.(10) The bureau may suspend or revoke the approval of a building system when the approval was issued in error or was issued on the basis of incorrect information or was issued in violation of these rules or is later found to be in violation of these rules. Notice of suspension or revocation of the approval shall be in writing with the reasons set forth therein. Appeals from suspensions or revocations shall receive timely review.Mich. Admin.
