<br />OJ2444 <br /> <br />Durango Pumoing Plant - Stage I <br /> <br />Table 03300E - Deviations from Specified Lines, Grades, and Dimensions <br /> <br />Ii <br />, <br /> <br />2. Variations from level or specified grades for slabs, beams, <br />and horizontal grooves: <br /> <br />(a) When overall length ofline or surface is: <br /> <br />Less than 10 feet <br /> <br />Exposed: :1:3/8 inch <br />Buried: :1:3/4 inch <br /> <br />F. <br /> <br />4. <br /> <br />10 feet or more <br /> <br />Exposed: :I: 1/2 inch <br />Buried: :I: I inch <br /> <br />(b) For any two successive intermediate points <br />on the line or surface separated by: <br /> <br />10 to 20 feet, inclusive <br /> <br />Exposed: 318 inch <br />Buried: 3/4 inch <br /> <br />More ihan 20 feet <br /> <br />Exposed: 1/2 inch <br />Buried: I inch <br /> <br />Surface Irregularities: <br /> <br />I. Bulges, depressions, and offsets are defined as surface irregularities or roughness. <br /> <br />2. Surface irregularities are classified as "abrupt" or "gradual" and allowable <br />tolerances are specified in Table 03300F - Surface Tolerances. <br /> <br />a. A surface tolerance is designated by a capital "T" followed by a number I <br />through 5. <br /> <br />b. Surface tolerance designations are separate from surface finishes and <br />structural deviations. <br /> <br />Abrupt Surface Irregularities: <br /> <br />a. Abrupt surface irregularities are defined as offsets such as those caused by <br />misplaced or loose forms in which maximum dimension of irregularity <br />perpendicular to surface is greater than maximum dimension of <br />irregularity in plane of surface. <br /> <br />b. Abrupt surface irregularities include all incidences of isolated surface <br />irregularities which exceed specified gradual irregularities. <br /> <br />Gradual Surface Irregularities: <br /> <br />a. Gradual surface irregularities are defined as bulges and depressions <br />resulting in gradual changes on surface. <br /> <br />b. Gradual surface irregularities are further defined as isolated undulations <br />on surface. Maximum dimension of undulation perpendicular to surface is <br />small relative to maximum dimension of undulation in plane of surface. <br /> <br />3. <br /> <br />Cast-in-Place Concrete <br />03300 - 40 <br /> <br />( <br /> <br />I <br />, <br />
