CHAPTER 9 FIRE PROTECTION SYSTEMS

901 GENERAL


901.2 Exception: Delete exception and replace with the following:
Exceptions:
   1. Any fire protection system or portion thereof not required by this code shall be permitted to be
       installed for partial or complete protection provided that such system meets the requirements of
       this code the applicable NFPA Standard.
   2. Where alternative fire protection designs, which vary from any prescriptive requirements of 780
       CMR 9.00, are to be utilized the owner shall engage an independent registered professional
       engineer to review said alternative design. The scope of the review shall include, but not be
       limited to:
           a. Design assumptions, methodologies, and resulting proposed system designs, to determine
               whether or not
                    i. the proposed fire protection systems and any other systems which are affected by
                       the alternative design, are consistent with the general objectives and prescriptive
                       provisions of 780 CMR 9.00
                   ii. they all conform to accepted engineering practice.

            b. Preparation of a written report to the building official as to the appropriateness of the
                proposed design specifically listing any variances from the prescriptive provisions of 780
                CMR 9.00 and describing, in detail, the design provisions used to achieve compliance.
       If the reviewing engineer concurs with the proposed design, the owner shall make application for
       a variance, to the State Building Code Appeals Board as provided in 780 CMR 122.0113.0. In
       addition to all supporting information and materials, the reviewing engineering‟s report required
       per this exception shall be included in the application for variance. A building permit shall not
       be issued until the variance, if required, has been granted, or unless the building permit is issued

       upon request of the owner, may provide that the variance shall be applicable to such future
       buildings. If such request is made, a quorum of the BBRS shall hear the appeal. Each such
       application to a future building will be subject to determination as prescribed in 780 CMR
       110.8107.1.2 by the building official in conjunction with the fire official that its use is in
       conformity with the terms of the variance.
