This presentation will cover all things steel tolerances. Understanding how straight a beam should be to how much lean a column can have is essential to producing a good design that avoids field fixes and compromise in the architectural design. The presentation will cover the AISC 303 “Code of standard practice for steel buildings” which is the document that the steel specifications reference for allowable fabrication and installation tolerances of steel members. Understanding this document is essential to being able to produce a design with the appropriate amount of tolerance so there are not clashes between the steel elements and architectural finishes. The presentation will also cover how steel tolerances can impact the ability to have flat floors and how to best set up the design documents to get the best product for the owner.
