Standard Specification addresses each of the Three-Part Section Format of the Construction Specifications Institute, organized by structural elements, structural components and types of structures; the numbering system reflects this organization. The offset between adjacent pieces of formwork facing material shall not exceed: All tolerances single plane and as shown.
If application of positive tolerance to Type 9 results in a chord length equal to or greater than the arc or bar length, the bar may be shipped straight. Where range is specified there is no tolerance. Each additional 10 ft increment in excess of 40 ft. Plus or minus 1. Clear distance – In reinforced concrete, the least distance between the surface of the reinforcement and the referenced surface, i.
When applied to roadways, bridge decks, slabs, ramps, or other nominally horizontal surfaces established by elevations, level alignment is defined as the vertical location of the surface relative to the specified profile grade and specified cross slope. The most restrictive tolerance controls.
This specification provides standard tolerances for concrete construction and materials. The permitted variation from a given dimension or quantity. For members with a span-to-depth ratio equal 17-10 or exceeding 30, the stated camber tolerance may require special production measures and result in cost premiums.
