ACI Specification for Tolerances for Concrete Construction and Materials ( ACI ) and Commentary (ACI R). Specification for Tolerances for Concrete Construction and Materials (ACI ) and Commentary. ACI contains a tolerance for the elevation of the top surface of formed suspended slabs, before removal of supporting shores (±3/4 inch, Section ).

Designate class of surface A, B, C, D: Plus or minus 1 in. Difference in width between adjacent trends. Please note that extra delivery cost and delivery time may apply for products ordered as hardcopy, as the products must first be shipped from our suppliers overseas.
Each additional 10 ft increment in excess of 40 ft. Other surfaces, deviation from a 1117-10 ft. If you like to setup a quick demo, let us know at support madcad. Vertical alignment – The location relative to specified vertical plane or a specified vertical line or from a line or plane reference to a vertical line or plane.
FL levelness tolerances shall not apply to cambered or inclined surfaces and shall be measured within 72 hr after slab concrete placement. Reduction in cover to formed soffits shall not exceed. Monitoring Aic monitoring is a free service designed for you who wish to be 1171-0 of changes to or new editions of aic standards required in your work.
Specialized concrete construction or construction procedures require specifier to include specialized tolerances. This service is not available if you are a URL user where you do not log in with an email address. Over 40 ft but not over 60 ft. For heights greater than ft. Member depth or thickness over 8 in.
When member size is over 12 in. Minus – tolerance decreases the amount or dimension to which it applies, or lowers a level alignment.
Guideway elements to be used as riding surface. For elements to be used as concrete guideways support and steering surfaces. Class D – Minimum quality surface where roughness is not objectionable, usually applied where surfaces will be concealed.
These mandatory requirements should designate the specific qualities, procedures, materials, and performance criteria acu which alternatives are permitted or for which provisions were not made in the Standard Specification.
For heights ft. When applied to battered walls, abutments or other nearly vertical surfaces, vertical xci is defined as the Fig. Greater than 2 ft. Manufacturers should be consulted for appropriate tolerances for their products.
Individual sections, articles, or paragraphs should not be copied into the Project Specifications since taking them out of context may change their meaning. One-quarter specified distance not to exceed.
Flashing reglets at panel 117-0. Level alignment – The location relative to a specified horizontal plane. Joints in Concrete Construction Reapproved For pipe with an internal diameter not greater than 42 in.
This specification provides standard tolerances for concrete construction and materials. 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.
Enter your account email address to request a password reset: Where a specific application uses multiply toleranced items that together yield a toleranced result, the specifier must analyze the tolerance envelope with respect to practical limits and design assumptions and specify its value where the standard tolerances values in this specification are 171-10 or inappropriate.
For elements which will not receive topping. Relative alignment – The distance between two or more elements in any plane, or the distance between adjacent elements, or the distance between an element and a defined point or plane. Remember me for one month. Tolerances in this specification are for standard concrete construction and construction procedures.
Bowing – The displacement of the surface of a planar element from a plane passing through any three corners of the element.
Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest 11-10. Print 1 2 3 4 5 page sstarting from page current page. For members with a span-to-depth ratio equal to or exceeding 30, the stated camber tolerance may require special 11-710 measures and result in cost premiums.
Industrial precast products may not conform to the planar tolerances. Total not more than. At discontinuous ends of members. acii
Roof elements without topping slab. In any 10 ft of height the centerpoint shall not change more than 1 in. This foreword is included for explanatory purposes only; it is not a part of Standard Specification
