Indiana Register, Volume 25, Number 4, January 1, 2002INDIANA DEPARTMENT OF LABORNOTICE OF CHANGES INENFORCEMENT OF STEEL ERECTION REGULATIONSThe federal Occupational Safety and Health Administration, effective January 18, 2002, has revised the steel erectionregulations contained in 29 CFR 1926, Subpart R. Effective 60 days after January 18, 2002, on March 19, 2002, the IndianaDepartment of Labor will be enforcing those regulations in Indiana.A number of provisions in the final rule, 29 CFR 1926, Subpart R, address the safety of certain structural components and theseprovisions are known as “component requirements.” Component requirements contain requirements for structural components tohelp ensure that the structure can be erected safely…


Slide7 l.jpg

Component RequirementsThe new effective date, March 19, 2001, for the steel erection standards contained in 1926 Subpart R will be applied to thecomponent requirements in the following manner:(1) Where a building permit was obtained before the final rule was published on January 18, 2001, the component requirementslisted above will not apply to the work project.(2) If the steel erection work in question began on or before November 15, 2001, the component requirements of the final rule,listed above, will not be applied.


Slide8 l.jpg

("component requirements")

Contain requirements for these components to help ensure that the structure can be erected safely.

For example, there are provisions that prohibit shear connectors on members before they are erected (§ 1926.754(c)(1)(i)); require all columns to be anchored by a minimum of 4 anchor bolts, which must meet specified strength requirements (§ 1926.755(a)) (there is a comparable requirement for systems-engineered metal buildings, § 1926.758(b)); set requirements for double connections (§ 1926.756(c)(1)) (there is a comparable requirement for systems-engineered metal buildings § 1926.758(e)); require column splices to be at a specified height and meet a strength requirement (§ 1926.756(d)); require perimeter columns to have holes or other devices for perimeter safety cables (§ 1926.756(e)); in some instances require a vertical stabilizer plate to stabilize steel joists (§ 1926.757(a)(1)(i)); require certain joists to be strong enough to allow one employee to release the hoisting cable without the need for erection bridging (§ 1926.757(a)(3)), and require certain joists to be fabricated to allow for field bolting during erection (§ 1926.757(a)(8)(i)).
