The maximum transverse elevation difference between wheel tracks; The maximum elevation difference between front and rear axle; and The maximum rate of change per foot for 1 and 2 as the vehicle travels down the aisle. The remedy for noncompliance with specified defined flatness tolerances should be included in specification language. For random traffic slabs-on-grade, the remedy can range from liquidated damages, to localized grinding, to application of a topping, to removal and replacement, depending on the purpose for which the slab is being installed.
The remedy for defined traffic installations is generally grinding of high spots. All slabs will shrink; joints and cracks in slabs-on-ground will curl with time, resulting in a surface that is less flat with the passage of time.
If the needs of the user are such that a delay in testing is necessary to allow successful installation of subsequent Work, this requirement for delayed testing should be clearly stated in the specifications. Survey lines should be parallel to the direction of slope. In instances where the Specifier chooses to provide a tolerance at construction joints, specific provisions for data collection should be included in the Project Specifications.
The system evaluates the levelness of a floor surface by measuring elevation changes relative to a horizontal plane and between points separated by a distance of 10 ft.
Higher numbers indicate better quality in the surface characteristic being reported. Consequently, after the entire floor has been installed, the system permits the immediate calculation of liquidated damages based on the final aggregate areas defective relative to either SOFF or SOFL whichever yields the larger penalty. These variations can be caused by normal occurrences, such as inconsistent setting time of concrete, changes in ambient conditions, or delays in delivery or placement of the concrete.
Acceptance or rejection of a minimum local area requires that data collection within the minimum local area in question meet the requirements of ASTM E Smaller gaps between the straightedge and supporting surface are indicative of higher flatness quality.
This method is not sufficiently precise to evaluate very flat and super-flat categories. Table 4. A sample is a single placement of the straightedge. The Specifier may provide alternative procedures as long as specific testing requirements and acceptance criteria are established. Test results should be reported in a manner that will allow the data to be verified or the test to be replicated. When using this approach to evaluate floor surfaces, levelness is subject to the provisions of Section 4.
Data collection procedures and evaluation of data shall comply with the requirements established in the Contract Documents or Section 4.
Data are taken using an instrument other than a straightedge and processed using a computer to produce results similar to that achieved using a manual straightedge. The flatness is evaluated by moving a simulated 10 ft long straightedge along each data line at 1 ft intervals. No ASTM standard has been developed to govern evaluation of a floor surface using this procedure, so the Specifier should provide specific testing requirements and acceptance criteria as described in the Mandatory Requirements Checklist.
Results should be reproducible. The Specifier is advised that current available software for computerized simulation of a freestanding 10 ft straightedge does not meet the requirements of Section 4. Each survey line used in the RMS levelness calculation shall be parallel with the others and all lines shall be in the direction of the pitch or tilt. Tolerances in this standard apply to cast-in-place concrete elements that interface with precast concrete elements.
Tolerances for tilt-up concrete are specified in Section More than 36 in. Greater than 12 in Refer to ACI Heights greater than ft Edges of openings, sleeves, and embedments greater than 12 in More than ft Horizontal deviation Concealed surfaces Refer to commentary Sections R4.

General notes G1. ACI Specification is intended to be used by reference or incorporation in its entirety in the Project Specification.
Do not copy individual Sections, Parts, Articles, or Paragraphs into the Project Specification, because taking them out of context may change their meaning. If Sections or Parts of ACI Specification are copied into the Project Specification or any other document, do not refer to them as an ACI specification because the specification has been altered.
Each technical section of ACI Specification in this Standard associated with items in the Mandatory Requirements Checklist are accompanied by text indicating an item in the section is specified in the Contract Documents.
ACI Specification is written to the Contractor. This Foreword is included for explanatory purposes only; it does not form a part of ACI Specification ACI Specification may be referenced by the Specifier in the Project Specification for any building project, together with supplementary requirements for the specific project.
Responsibilities for project participants must be defined in the Project Specifications. ACI Specification cannot and does not address responsibilities for any project participant other than the Contractor.
The Optional Requirements Checklist identifies Specifier choices and alternatives. The Checklist identifies the Sections, Parts, and Articles of the Reference Specification and the action required or available to the Specifier.
The Specifier should review each of the items in the Checklist and make adjustments to the needs of a particular project by including those selected alternatives as mandatory requirements in the Project Specifications. Checklists do not form a part of ACI Specification Checklists assist the Specifier in selecting and specifying project requirements in the Project Specifications.
Building codes set minimum requirements necessary to protect the public. ACI Specification may stipulate requirements more restrictive than the minimum. The Specifier shall make adjustments to the needs of a particular project by reviewing each of the items in the checklists and including those the Specifier selects as mandatory requirements in the Project Specifications.
The Mandatory Requirements Checklist indicates Work requirements regarding specific qualities, procedures, F7. Recommended references—Documents and publications that are referenced in the Commentary of ACI Specification are listed below. These references provide guidance to the Specifier and are not considered to be part of ACI Specification Martinez, J. Specific use of a tolerance item may warrant less or more stringent tolerances than contained in the specification.
Identify in the Contract Documents any tolerances the Contractor is required to achieve, but are not addressed in ACI Coordinate tolerances for concrete construction and those of any materials that interface with, or attach to, the concrete structure. Specify concrete tolerances that are more or less stringent than those contained in this specification.
Specification of more restrictive tolerances for specialized constructions, such as architectural concrete, often results in an increase in material cost and time of construction. The Specifier should specify dimensional tolerances considered essential to successful execution of the design. Success may require one or more of the individual tolerances to be more restrictive than those contained in ACI Successful resolution of any questions will almost certainly require active participation of the Design Professional.
Specify acceptance criteria in accordance with ACI or equivalent. Section 2—Materials 2. Section 3—Foundations Specify category of drilled pier. The Specifier should be aware that the recommended vertical alignment tolerance of 1. Section 4—Cast-in-place concrete for buildings 3. Designate Section 4. Refer to Table R4. Refer to Tables 4. Designate Floor Surface Classification. Section 5—Precast concrete Specify tolerances for precast concrete.
Section 6—Masonry Specify tolerances for masonry elements. Section 11—Cast-in-place bridges Specify method of testing. ACI committee documents covering specialized construction may provide guidance on specialized tolerances. Specify tolerances for Architectural Concrete. Where possible, excess cover to other protection of the reinforcing steel should be specified instead of reduced tolerance because of the accuracy of locating reinforcing steel using standard fabrication accessories and installation procedures.
Specific design use of embedded items may required the Specifier to designate tolerances of reduced magnitude for various embedded items. Section 3—Foundations 3. Refer to ACI for guidance. Plus tolerance for the vertical dimension is not specified because no limit is imposed. Specifier should designate plus tolerance if desired. Specifiers are cautioned that a tighter tolerance should be specified where there is a potential for cutting reinforcement.
Designate distribution of test reports. Specify minimum number of samples, test procedure must be reproducible , and acceptance criteria.
