“(2) Any repairs, replacements and modifications to the anchor bolts were conducted in accordance with § 1926.755(b).”
“(b) Commencement of steel erection. A steel erection contractor shall not erect steel unless it has received written notification that the concrete in the footings, piers and walls or the mortar in the masonry piers and walls has attained, on the basis of an appropriate ASTM standard test method of field-cured samples, either 75 percent of the intended minimum compressive design strength or sufficient strength to support the loads imposed during steel erection.”
“(1) Adequate access roads into and through the site for the safe delivery and movement of derricks, cranes, trucks, other necessary equipment, and the material to be erected and means and methods for pedestrian and vehicular control. Exception: this requirement does not apply to roads outside of the construction site.”
“(d) Pre-planning of overhead hoisting operations. All hoisting operations in steel erection shall be pre-planned to ensure that the requirements of § 1926.753(d) are met.”
“(e) Site-specific erection plan. Where employers elect, due to conditions specific to the site, to develop alternate means and methods that provide employee protection in accordance with § 1926.753(c)(5), § 1926.757(a)(4) or § 1926.757(e)(4), a site-specific erection plan shall be developed by a qualified person and be available at the work site. Guidelines for establishing a site-specific erection plan are contained in appendix A to this subpart.”
Free practice questions on 29 CFR 1926.752
Question 1
A controlling contractor is preparing to let a steel erector start setting columns on new cast-in-place concrete piers. Field-cured cylinder breaks, tested by an appropriate ASTM method, show the concrete has reached 60 percent of the intended minimum compressive design strength. The engineer has not stated that the piers can support the erection loads. What should the steel erection contractor do?
Show answer and source
Answer: C. Not erect steel until it has written notification that the concrete has reached 75 percent of design strength or sufficient strength to support erection loads
OSHA's steel erection rule, 29 CFR 1926.752(b), bars the erector from erecting steel until it receives written notice that the concrete has reached 75 percent of its intended minimum design strength or enough strength to carry erection loads. Sixty percent with no strength statement meets neither condition. Verbal approval, erecting only perimeter columns, and graded access roads do not replace that written notice.
On the job
A project engineer for a steel erector reviews the foundation package for a wind turbine tower base before scheduling the first lift. The only documentation is an email saying the pedestal concrete was tested and looks fine. The engineer holds the lift and requests a written notice stating that field-cured samples reached 75 percent of the intended minimum compressive design strength or that the concrete can support erection loads, because no steel is erected without that written notification.

29 CFR 1926.752(b)(opens ecfr.gov in a new tab)“A steel erection contractor shall not erect steel unless it has received written notification that the concrete in the footings, piers and walls or the mortar in the masonry piers and walls has attained, on the basis of an appropriate ASTM standard test method of field-cured samples, either 75 percent of the intended minimum compressive design strength or sufficient strength to support the loads imposed during steel erection.”
Question 2
A controlling contractor is about to let a steel erector begin setting columns. The erector already holds written notice that the footing concrete has reached the required strength. During anchor bolt checks, a few bolts were found out of position, and the concrete contractor repaired and modified them. No one has told the erector in writing how those repairs were done. What should the controlling contractor do before authorizing steel erection to start?
Show answer and source
Answer: D. Give the erector written notice that the anchor bolt repairs and modifications were done in accordance with the anchor bolt requirements of the steel erection standard
OSHA's steel erection standard says the controlling contractor must ensure the erector gets written notice that any anchor bolt repairs, replacements and modifications followed the anchor bolt rule. The concrete strength notice is a separate item. Verbal assurance is not written notice, and checking the bolts after columns are set comes too late.
Answer D rests on
