Construction Tolerances


Construction TolerancesDesign Assumptions◦ All materials have specific dimensional sizes

◦ 24” x 24” Concrete Column

◦ All construction elements are dimensioned to a theoretically exact position relative to 1 or more datum points.◦ Centered on the Grid Lines

Construction Reality◦ Dimensional sizes and position vary slightly◦ How much variance?

◦ Shop-fabricated components = 0.001”◦ Working Point of a Column = 2”-3”


Building Layout (Horizontal) ISO 4463-1 Measurement Methods for Buildings - Setting out and Measurement◦ Describes procedures for establishing a survey grid,

relating it to a building site, and establishing building layout and control points based on property boundaries and major survey control points.

Primary System = official control system (site)◦ National or municipal coordinate system

Secondary System = Grid reference◦ ± 3/16” up to 13’-0” (linear dimensional tolerance)◦ ± 3/8” in 100’-0” (right angle layout)

Position Points = location of individual elements◦ Horizontally + Vertically◦ ± 1/8” up to 13’-0” (linear dimensional tolerance)


Building Layout (Horizontal)


Building Layout (Horizontal) Right Angle (90°) as Offset ◦ Steel Tape = ± 3/4” in 100’-0”◦ Micropter Transit = ± 1/8” in 100’-0”◦ Const Laser = ± 1/32” in 100’-0”

Linear Dimensions◦ Steel Tape

◦ ± 1/8” up to 10’-0” ◦ ± 1/4” 10’-0” to 100’-0”

◦ Const Laser = ± 1/16” up to 6000’-0”

Position Points◦ ± 1/8” up to 13’-0” ◦ ± 5/16” in 100’-0”

ISO 4463-1 : Acceptable Plumb Deviation ◦ ± 1/8” up to 13’-0”◦ ± 5/16” up to 100’-0”

Level◦ Spirit Level = ± 1/4” in 20’-0”◦ Water Level = ± 1/8” in 30’-0”◦ Optical Level = ± 1/8” in 200’-0”◦ Laser Level = ± 1/16” in 100’-0”◦ Digital Level = ± 1/16” in 3280’-0”

ISO 4463-1 : Acceptable Vertical Deviation ◦ Primary to Secondary Benchmark = ± 3/16”◦ Secondary to Secondary Benchmarks

◦ ± 1/8” up to 13’-0”

◦ Secondary Benchmarks to Position = ± 1/8”


Construction TolerancesConcrete : Slabs on Grade ◦ Above/Below specified elevation◦ Levelness

◦ Degree to which the surface parallels horizontal◦ Flatness

◦ Degree to which the surface approximates a plane

Levelness ◦ Over the entire surface of a conc slab, all points

must fall within an envelope 3/4” above/below the elevation plane.

Flatness : 10’ straightedge set test◦ Conventional : 1/2” - 3/4”◦ Moderately Flat : 3/8” - 5/8”◦ Flat : 1/4” - 3/8”

Construction Tolerances2010 ADA Standards

Chapter 1: Application and Administration

104.1 Dimensions. ◦ Dimensions that are not stated as “maximum” or

“minimum” are absolute.

104.1.1 Construction and Manufacturing Tolerances. ◦ All dimensions are subject to conventional

industry tolerances except where the requirement is stated as a range with specific minimum and maximum end points.


Construction TolerancesANSI-A117.1 2009

104.2 Dimensions. ◦ Dimensions that are not stated as

"maximum" or "minimum" are absolute. ◦ All dimensions are subject to conventional

industry tolerances.

Different from ADA◦ NO “except where the requirement is

stated as a range with specific minimum and maximum end points.”


Construction TolerancesAdvisory 104.1.1 Construction and Manufacturing Tolerances.

Conventional industry tolerances recognized by this provision include those for field conditions and those that may be a necessary consequence of a particular manufacturing process. Recognized tolerances are NOT intended to apply to design work.

It is good practice when specifying dimensions to avoid specifying a tolerance where dimensions are absolute. For example, if this document requires "1 inches," avoid specifying "1 inches plus or minus X inches."

Where 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 floor, the range provides an adequate tolerance and therefore no tolerance outside of the range at either end point is permitted.

Where a requirement is a minimum or a maximum dimension that does not have two specific minimum and maximum end points, tolerances may apply. Where an element is to be installed at the minimum or maximum permitted dimension, such as "15 inches minimum" or "5 pounds maximum", it would not be good practice to specify "5 pounds (plus X pounds) or 15 inches (minus X inches)." Rather, it would be good practice to specify a dimension less than the required maximum (or more than the required minimum) by the amount of the expected field or manufacturing tolerance and not to state any tolerance in conjunction with the specified dimension.

Specifying in the manner described above will better ensure that facilities dimensions in design and elements accomplish the level of accessibility intended by these requirements. It will also more often produce an end result of strict and literal compliance with the stated requirements and eliminate enforcement difficulties and issues that might otherwise arise. Information on specific tolerances may be available from industry or trade organizations, code groups and building officials, and published references.

Dimensioning : WHAT?Dimensioning DOs

DO plan (cartoon) Dimension strategy◦ What was the Design Intent?

◦ Symmetry?◦ Aligning with other and/or existing components?

DO consider how Dimensions will be affected by future revisions (XA-sheets).◦ Say it once …

◦ Dimensioning in multiple views will require add’t XA sheets

Dimensioning DO NOTs

DO NOT duplicate Dimensions in other Views◦ Call-outs should not have annotation

(dimensions, partition types, keynotes, etc) in the source view …. Save it for the call-out

◦ Do not Dimension components in elevation that are located in plan

DO NOT duplicate Dimensions per the Specs◦ Spec may give instructions where (extent) and

how (method) certain components are to be installed

SDI 127F-02Butted Frames Rough Opening Sizes

It has been “customary” to allow 1/4" clearance around the frame perimeter when establishing rough opening sizes …

We therefore recommend that the rough openings for these cases be no less than 3/16" larger on all 3 sides than the “intended” overall frame size.

Dimensioning : WHEN?


Dimensioning : WHEN?It depends …

Consider the sequencing of construction

Once the Structural Components (foundation, bearing walls, columns, beams, slabs w/openings) and Grid Lines have been set, the locations of the Architectural components are determinate on these "in-place" benchmarks

Use Grid Lines as common project Benchmarks
