564.01 Description

This work is meeting the specified tolerances for the listed structure elements.

564.02 Reserved

564.03 Construction Requirements

Meet the tolerances shown in Table 564-1. In case of conflicting tolerances, the tighter tolerance controls. Increase precision as necessary to meet other contract requirements.

1.The Project Manager may approve requests for exceptions as necessary to avoid interference with anchor bolts or other conflicts. 2020 EDITION V5.1 STRUCTURE TOLERANCES – 564 564-3
2.Curved concrete barrier may be constructed of tangent segments, each having a maximum length of 10 feet (3 m). In the event an item does not meet a specified tolerance, the Project Manager may approve an exception if it is determined that there will be no detrimental effect to the structure. If the Project Manager determines that a nonconforming item may be detrimental to the structure, submit a written plan for approval that details corrective action.
