Internal Dimensions —The internal dimension shall not vary more than 1 <br /> 11 percent or 2 inches, whichever is less, from the Plan dimensions. The haunch <br /> I 12 dimensions shall not vary more than 3/4 inch from the Plan dimensions. <br /> 13 <br /> 14 2. Slab and Wall Thickness —The slab and wall thickness shall not be less than <br /> I 15 that shown in the Plans by more than 5 percent or 1/2 inch, whichever is <br /> 16 greater. A thickness more than that required in the Plans will not be a cause <br /> 17 for rejection if proper joining is not affected. <br /> 18 <br /> I <br /> 19 3. Length of Opposite Surfaces —Variations in lengths of two opposite surfaces <br /> 20 of the three-sided section shall not be more than 3/4 inch unless beveled <br /> 21 sections are being used to accommodate a curve in the alignment. <br /> I22 <br /> 23 4. Reinforcing steel placement shall meet the tolerances specified in Section 6- <br /> 24 02.3(24)C. <br /> I 25 <br /> 26 Tolerances for PRCBC and PRCSBC shall be as follows: <br /> 27 <br /> I 28 1. Internal Dimensions —The internal dimensions shall not vary more than 1 <br /> 29 percent from the Plan dimensions. If haunches are used, the haunch <br /> 30 dimensions shall not vary more than 1/4 inch from the Plan dimensions. <br /> I 31 <br /> 32 2. Slab and Wall Thickness —The slab and wall thickness shall not be less than <br /> 33 that shown in the Plans by more than 5 percent or %6 inch, whichever is <br /> 34 greater. A thickness more than that required in the Plans will not be a cause <br /> I 35 for rejection. <br /> 36 <br /> 37 3. Length of Opposite Box Segments—Variations in lengths of two opposite <br /> 1 38 surfaces of the box segments shall not be more than 1/8 inch per foot of internal <br /> 39 span, with a maximum of 5/ inch for all sizes through 7 feet internal span, and <br /> 40 a maximum of 3/4 inch for internal spans greater than 7 feet, except where <br /> I 41 beveled sections are being used to accommodate a curve in the alignment. <br /> 42 <br /> 43 4. Length of Box Segments —The underrun in length of a segment shall not be <br /> I <br /> 44 <br /> 45 more than 1/8 inch per foot of length with a maximum of inch in any box <br /> segment. <br /> 46 <br /> I 47 5. Length of Legs and Slabs —The variation in length of the legs shall not be <br /> 48 more than 1/ inch per foot of the rise of the leg per leg with a maximum of/8 <br /> 49 inches. The differential length between opposing legs of the same segment <br /> 50 shall not be more than 1/2 inch. Length of independent top slab spans shall not <br /> I 51 vary by more than 1/2 inch per foot of span of the top slab, with a maximum of <br /> 52 5/ inches. <br /> I <br /> I AMENDMENTS TO THE 2016 STANDARD SPECIFICATIONS BOOK <br /> Revised: 811116 <br />
