Sections

28-8. General Requirements.

Steel Erection Activities

Include activities such as hoisting, welding, and rigging structural steel, among others.
Involve installing materials like metal decking, miscellaneous metals, and ornamental iron.
Require moving point-to-point during these activities.

Written Notifications for Steel Erection

The controlling contractor must provide written notifications to the steel erector before starting steel erection.
Notifications must confirm the concrete's strength and any repairs or modifications to the anchor bolts.
Both steel and concrete contractors must keep a copy of this notification onsite.

Fall Protection and Load Management

Fall protection is mandatory at heights over 6 feet for all work, including steel erection.
Employers must ensure structures can support construction loads based on qualified structural design advice.
Employees must not work above or near protruding hazards without hazard control measures.

Site Layout and Safety

The controlling contractor must ensure safe access roads, storage areas, and hoisting operation pre-planning.
Employees are prohibited from working under suspended loads, with specific exceptions and control measures.
Site layout should facilitate safe delivery, movement of equipment, and material storage.

EM 385-1-1 Paragraph 28-8 (a.–g.).

28-8. General Requirements. (a.–g.).

a.  Steel erection activities include but are not limited to, hoisting, laying out, placing, connecting, welding, burning, guying, bracing, bolting, plumbing, and rigging structural steel, steel joists and metal buildings; installing metal decking, miscellaneous metals, ornamental iron, and similar materials; and moving point-to-point while performing these activities (see 29 CFR 1926.750 (29 CFR 1926 Subpart R)).  (28-8.a)

b.  Written Notifications.  Before authorizing the commencement of steel erection, the controlling contractor must ensure that the steel erector is provided with the following written notifications:  (28-8.b)

(1) The concrete in the footings, piers, and walls has attained, on the basis of an appropriate ASTM standard test method of field-cured samples, either 75% of the intended minimum compressive design strength or sufficient strength to support the loads imposed during steel erection.

(2) Any repairs, replacements, and modifications to the anchor bolts were conducted according to with contract specifications or project structural engineer of record.

Note. Both steel and concrete contractors must keep a copy of this written notification onsite.

c. The fall protection threshold height requirement is 6 feet (1.8 m) for all work covered by this manual, whether performed by Government or contractor work forces, unless specified differently below. This includes steel erection activities and systems- engineered activities (that is, prefabricated metal buildings).  (See chapter 21) (28-8.c)

d.  Do not place construction loads on a structure or portion of a structure unless the employer determines, based on information from a person who is qualified in structural design, that the structure or portion of the structure can support the loads. (28-8.d)

e.  Do not permit employees to work above or in positions exposed to protruding reinforcing steel, fasteners, or other impalement hazards unless provisions have been made to control the hazard.  (28-8.e)

f.  Do not permit employees to work under bundled material loads or other suspended loads.  Riggers securing lower loads to multi-lift rigging assemblies and workers setting suspended structural components such as beams, trusses, and precast members are excluded from this requirement.  In these cases, work controls must be used to minimize the time spent directly under loads.  (28-8.f)

g.  Site layout. The controlling contractor must ensure that the following is provided and maintained:  (28-8.g)
(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.

Note. This requirement does not apply to roads outside of the construction site.

(2) An adequately compacted, properly graded, drained area readily accessible to the work with adequate space for the safe storage of materials and the safe operation of the erector’s equipment.

(3)  Pre-planning of overhead hoisting operations.  Pre-plan all steel erection hoisting operations.
