(e) Minimum Acceptable Quality of Existing Unreinforced <br /> Masonry Walls. <br /> (1) General Provisions. All unreinforced masonry <br /> walls utilized to carry vertical loads and seismic <br /> forces parallel and perpendicular to the wall <br /> plane shall be tested as specified in this <br /> subsection. All masonry quality shall equal or <br /> exceed the minimum standards established herein or <br /> shall be removed and replaced by new materials. <br /> Alternate methods of testing may be approved by <br /> the Building Official. The quality of mortar in <br /> all masonry walls shall be determined by <br /> performing in -place shear tests or by testing <br /> eight inch diameter cores. Alternative methods of <br /> testing may be approved by the Building Official. <br /> Nothing shall prevent pointing with mortar of all <br /> the masonry wall joints before the tests are first <br /> made. Prior to any pointing, the mortar joints <br /> must be raked and cleaned to remove loose and <br /> deteriorated mortar. Mortar for pointing shall be <br /> Type S or N except that masonry cements shall not <br /> be used. All preparation and mortar pointing <br /> shall be done under the continuous inspection of <br /> a designated special inspector. At the conclusion <br /> of the inspection, the inspector shall submit a <br /> written report to the licensed engineer or <br /> architect responsible for the seismic analysis of <br /> the building setting forth the result of the work <br /> inspected. Such report shall be submitted to the <br /> Building Official for approval as part of the <br /> structural analysis. All testing shall be <br /> performed in accordance with the requirements <br /> specified in this subsection by a testing agency <br /> approved by the Building Official. An accurate <br /> record shall be kept of all such tests and of <br /> their locations in the building, and these <br /> results shall be submitted to the Building <br /> Official for approval as part of the structural <br /> analysis. <br /> (2) Number and Location of Tests. The minimum number <br /> of tests shall be two per wall or line of wall <br /> elements resisting a common force, or 1 per 1500 <br /> square feet of wall surface, with a minimum of <br /> eight tests in any case. The exact test or core <br /> location shall be determined at the building site <br /> by the licensed engineer or architect responsible <br /> for the seismic analysis of the subject building. <br /> 11 <br /> • <br />
