INSTRUCTOR: Alexander Newman, P.E., F.ASCE
Purpose and Background
It is impractical to expect that every dimension and every design detail indicated in the construction drawings will be built precisely as shown. Instead, the best we can expect is that the work will be built reasonably close to the drawings, within the established construction tolerances. But which dimensional deviations are acceptable? Where is this information provided? What specifically should the design engineer do to allow the building element to function even when the dimensions are not as shown on the drawings but still within the industry-accepted tolerances? Who is to blame when some component does not fit, and the contractor's work complied with the relevant tolerances? The last issue is unfortunately a common cause of construction problems and claims. This webinar answers these and many other practical questions related to incorporating construction tolerances in the design drawings, with a focus on dimensional tolerances. Specific examples illustrate how tolerances affect structural design details.
Primary Discussion Topics
- The definition of construction tolerances
- Tolerances in structural steel elements
- Concrete tolerances
- Tolerances in masonry construction
- How to deal with conflicting tolerances
Learning Outcomes
Webinar Benefits
- Understand whether flatness and levelness limits for slabs on grade apply to elevated slabs as well
- Know how masonry tolerances affect the common practice of embedding steel wires and anchors into masonry joints
- Learn about two simple details to assure that the tops of steel beams and open-web steel joists bearing on masonry walls are in alignment
- Find out what can be done if the project requires tighter tolerances than commonly accepted
- Discover how construction tolerances could make a common masonry design approach questionable
Assessment of Learning Outcomes
Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and fill in the blank questions).
Intended Audience

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion
To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.
How do I convert CEUs to PDHs?
1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
