Drawings and general provisions of the Contract, including General and <br />Supplementary Conditions and Division 01 Specification Sections, apply to this <br />Section. <br />1.2 SUMMARY <br />A. This Section includes grouted, reinforced masonry consisting of grout and reinforcing <br />steel. <br />B. Related Sections: <br />1. Section 03 20 00 "Concrete Reinforcement" for reinforcing steel. <br />2. Section 03 30 00 "Cast-In-Place Concrete" for concrete. <br />1.3 DEFINITIONS <br />A. CMU(s): Concrete masonry unit(s). <br />B. Reinforced Masonry: Masonry containing reinforcing steel in grouted cells. <br />1.4 PERFORMANCE AND PRECONSTRUCTION TESTING REQUIRMENTS <br />A. Provide structural unit masonry that develops indicated net-area compressive <br />strengths at 28-days. Contractor shall determine the net-area compressive strength <br />of masonry based on 1.4B or 1.4C. Mortar for unit masonry shall comply with ASTM <br />C270. Contractor shall meet ASTM C270 requirements based on the Property or <br />Performance Specification. <br />B. Determine net-area compressive strength of masonry from average net-area <br />compressive strengths of masonry units and mortar types (unit-strength method) <br />according to Tables 1 and 2 in ACI 530.1/ASCE 6/TMS 602. <br />1. Preconstruction Testing Service: Owner will engage a qualified independent <br />testing agency to perform preconstruction testing indicated below. Retesting of <br />materials that fail to comply with specified requirements shall be done at <br />Contractor's expense. <br />a. Concrete Masonry Unit Test (Property and Performance Specification): For <br />each type of unit required, according to ASTM C 140 for compressive <br />strength.
