34、 Tolerancesfor Concrete Construction and Materials (ACI 117M-10).”The purpose of the commentary is to provide an illustrativeand narrative complement to the specification; it is not apart of the specification.No structure is exactly level, plumb, straight, and true.Tolerances are a means to establis

35、h permissible variation indimension and location, giving both the designer and thecontractor limits within which the work is to be performed.They are the means by which the designer conveys to thecontractor the performance expectations upon which thedesign is based or that the project requires. Such

36、 specifiedtolerances should reflect design assumptions and projectneeds, being neither overly restrictive nor lenient.Necessity rather than desirability should be the basis ofselecting tolerances.As the title “Specifications for Tolerances for ConcreteConstruction and Materials (ACI 117M)” implies,

37、thetolerances given are standard or usual tolerances that applyto various types and uses of concrete construction. They arebased on normal needs and common construction techniquesand practices. Specified tolerances at variance with thestandard values can cause both increases and decreases inthe cost

38、 of construction.Economic feasibilityThe specified degree of accuracy hasa direct impact on the cost of production and the constructionmethod. In general, the higher degree of constructionaccuracy required, the higher the construction cost, and thelower the degree of construction accuracy, the highe

39、r thecost of required repairs.Relationship of all componentsThe required degree ofaccuracy of individual parts can be influenced by adjacentunits and materials, joint and connection details, and thepossibility of the accumulation of tolerances in criticaldimensions.Construction techniquesThe feasibi

40、lity of a tolerancedepends on available craftsmanship, technology, materials,and project management.CompatibilityDesigners are cautioned to use finish andarchitectural details that are compatible with the type andanticipated method of construction. The finish and archi-tectural details used should b
