I <br /> ' B. Reinforced concrete shall conform to ACI Specification 318-89 or latest revision. <br /> C. Field testing and inspection services required will be provided by the Contractor. <br /> I Cost of such work, except as specifically stated otherwise, will be paid for by the <br /> Contractor. Methods of test will comply in detail with the latest applicable ASTM <br /> Methods of Testing. <br /> 1 D. Samples of constituents and of concrete as placed will be subjected to laboratory <br /> tests. Materials incorporated in the work shall conform to approved samples. <br /> ' E. Under special circumstances, the Engineer may allow minor deviations from the <br /> material requirements specified, provided the resulting concrete quality is not <br /> adversely affected or provided a suitable adjustment in cement content is made to <br /> Icompensate for such deviations without cost to the Owner. <br /> 1.05 SUBMITTALS <br /> 1 A. Submit, as provided in the General Conditions and Section 01340, shop drawings <br /> showing placement of forms, form joints, major inserts and blockouts. <br /> 1.06 QUALITY ASSURANCE <br /> A. The actual acceptance of aggregates and development of mix proportions to <br /> I produce concrete conforming to the specific requirements shall be determined by <br /> means of prior laboratory tests made by the Concrete Supplier or the Contractor at <br /> his expense with the constituents to be used on the work. <br /> IB. The Concrete Supplier shall submit through the Contractor to the Engineer for <br /> approval the concrete mix he intends to use, designed within the limits of these <br /> specifications, listing the brand of cement, source and results of tests of <br /> I aggregates and admixtures not later than 14 days prior to the beginning of placing <br /> concrete. <br /> 1 C. The limiting strengths, water-cement ratios and cement factors as shown on (Table <br /> A) shall apply. Maximum water-cement (#/#) for structures shall be 0.53 by weight. <br /> ITABLE A <br /> Minimum Maximum Net Minimum <br /> Comp. Str.
