As the title “Specifications for Tolerances for Concrete Construction and Materials (ACI 117)” implies, the toler-ances given are standard or usual tolerances that apply to various types and uses of concrete construction. Hence, the accumulation of tolerances of several inches in overall dimension is not unusual. Here, the Preface, Table of Contents, Foreword and Scope of most Australian Standards are available. Thus a tolerance in level of a ceiling amounting to ¼ inch in 10 feet(1)* of length could represent con-crete that is up to ¼ inch(2) above the target level or as much as ¼ inch below. Some members of the industry have argued that printed standards increase a surveyor’s liability.

The JISC is composed of many nationwide committees … The Residential Construction Performance Guidelines suggest a tolerance limit of 1/2″ in 32″ horizontally or 1/2″ in 8ˈ vertically for walls that have a bow. Appendices to this standard give information relating to site surveys, examples of the calculation of tolerances, characteristic accuracy values, and data from a BRE survey. Tolerances in construction are generally a variation in a dimension, construction limit, or physical char-acteristic of a material. In single family construction, lumber type and grade, span, spacing and load bearing capacities are tightly controlled by code, while the carpentry foreman uses his own judgment in determining the exact layout.

This document updates and replaces the Government Construction Common Minimum Standards for the procurement of the built environments, published in 2012.. Complete to within ± 0.1 foot of designated grade at time of final acceptance, except when rock subgrade is specified, the tolerance is ± 0.2 foot. w�`�! When the requirement states a specified range, such as in section 609.4 where grab bars must be installed between 33 inches and 36 inches above the finished floor, that range provides an adequate tolerance. Traditional brick and block remains the most common construction method in new homes. and industry concerns that identified a need to collate general building standards and tolerances into one, easy to read document. Standards 1 Formwork 1a Formwork dimensions and openings for services 1) Tolerance for cross-sectional dimensions of cast in-situ & precast elements: +10mm / -5mm 2) Tolerance for penetration / opening for services: +10mm for size and ±25mm for location 3) Tolerance for length of precast members (major dimension of unit): The surveyor who fails to perform up to a standard, either through ignorance or incompetence, will eventually be brought to task.

Tolerances for Concrete Foundation Construction as per ACI 117M-10 1. The Handbook of Construction Tolerances suggests a maximum misalignment of 1/8″ for adjacent framing members when gypsum wallboard is being directly attached to them. So with this industry standard, if the drawings specified 34” AFF maximum or just 34” AFF to the top of the counter, the industry tolerance would allow for 34¼” for actual installation since the dimension was either an open range dimension and in the second option an absolute dimension. 1.1.2 The indicated tolerances govern unless other-wise specified.
