Abstract:
Clearly defined tolerance specifications can help prevent disagreements about deviations between as-built dimensions and those indicated on project drawings. The Instituto del Cemento y del Hormigón de Chile (ICH) Committee on Technical Specifications for Contracts has developed ET 004-06, "Dimensional Tolerances in Reinforced Concrete Elements," based on data from several different sources. The specification provides a consistent set of tolerances for six surface finish grades and also establishes appropriate repair procedures for cases of noncompliance.
