Precast linear element – Beam, column, or similar unit. Specific design use of embedded items nay require the specifier to designate tolerances of reduced magnitude for various embedded items. Search book title Enter keywords for book title search. The gap at any point between the straightedge and the floor and between the 17-10 shall not exceed: Control of Cracking in Concrete Structures Reapproved There were no books found for the applied search filters.
Vertical alignment – The location relative to specified vertical plane or a specified vertical 1117-10 or from a line or plane reference to a vertical line or plane. Where feasible, a greater tolerance magnitude should be utilized where the span-to-depth ratio is equal to or greater than Spiral – As used in circular stave silo construction, is defined as the distortion that results when the staves are misaligned so that their edges are inclined while their outer faces are vertical.
For pipe with an internal diameter not greater than 42 in.

Variations to these tolerances may be advisable after consideration of panel size and construction techniques required. Contract documents – The project contract, the project drawings, and the project specifications.
The tolerances in this Specification do not apply to special structures or procedures not cited in the document such as nuclear reactors and containment vessels, bins and silos, circular prestressed concrete tank structures and shotcrete.
